    Quick Charge

    Quick Charge (QC) is a proprietary battery charging protocol developed by Qualcomm, used for managing power delivered over USB, mainly by communicating to the power supply and negotiating a voltage.

    Quick Charge is supported by devices such as mobile phones which run on Qualcomm SoCs, and by some chargers; both device and charger must support QC, otherwise, QC charging is not attained. It charges batteries in devices faster than standard USB allows by increasing the output voltage supplied by the USB charger while adopting techniques to prevent battery damage caused by uncontrolled fast charging and regulating the incoming voltage internally.
    Most chargers supporting QC Charger 2.0 and later are wall adaptors, but it is implemented on some in-car chargers, and some power banks use it to both receive and delivery charges.

    Quick Charge is also used by other manufacturers' proprietary rapid-charging systems.

  How many kinds of Cosmetic Machinery are there?

    Cosmetic machinery is a necessity for a cosmetics factory. There are many types of them, but they all have one thing in common, that is, they are all used in the production of cosmetics. Including vacuum emulsifiers, liquid filling machines, paste filling machines, perfume-making machines, perfume freezers, lipstick production lines, pressed powder production lines, etc. ; ;

    A vacuum emulsifier refers to the mechanical equipment that stirs and shears the material and finally achieves the emulsification effect. It is the leading equipment and core machine of a cosmetics factory and the lifeblood of a cosmetics enterprise. It is mainly used in the production of creams, lotions, essences, hand creams, skin creams, body lotions, facial cleansers, and other products. In addition, vacuum emulsifiers can also be applied to daily chemicals and pharmaceuticals. It can be regarded as multi-functional cosmetic machinery and equipment. It is also an entry choice for a cosmetics company.

    A liquid filling machine refers to cosmetic machinery and equipment for filling, sealing, and packaging liquid cosmetics. The machine has several filling heads to infuse liquid cosmetics into bottles and other packaging materials through hoses. Some liquid filling machines are equipped with a tail sealing machine, which will seal the bottom immediately after filling and implement one-stop production of cosmetic machinery and equipment.

    The perfume-making machine and the perfume refrigerator are used for perfume production, which can mix, stir, freeze and filter perfume. The volume of the perfume machine is relatively small compared to the vacuum emulsifier mixer.

    Medical device manufacturing: Best practices, applications, and regulations

    The term medical device covers an extensive range of applications from tongue depressors and latex gloves to x-ray machines and further to custom hearing aids and biomedical implanted devices such as heart valves. Traditional manufacturing processes including CNC machining and injection molding are typically used for the many existing medical devices such as prosthetics, surgical tools, and general equipment/tools used by medical professionals.

    The field of Medical Products Making machines ;is rapidly growing and, given the advantages offered by additive manufacturing – highly customizable geometry, low cost, and a wide variety of possible materials – these processes are well suited to fill the demand for the emerging needs of medical device manufacturing.

    Processes used to manufacture medical devices

    Whether additive manufacturing or traditional manufacturing processes is the best solution for medical devices depends on a number of factors including overall schedule and application. ;

    In general, traditional manufacturing processes such as CNC machining or injection molding are best suited for higher volume parts because of the higher start-up costs and longer lead times for tooling. Additive manufacturing is better suited for unique or low-volume parts as well as prototypes or proof-of-concept designs.

    Applications for Medical Products Making Machine

    There's a wide range of applications for Medical Products Making Machine given the broad category of products classified as medical devices – from tongue depressors and latex gloves to x-ray machines and further to custom hearing aids and biomedical implanted devices such as heart valves. ;

Highway Barrier
Precast concrete highway barriers ;are the go-to product for vehicular and construction worker safety, in addition to building security. Precast concrete barriers have the unique ability to not only realign stray vehicles but also reduce their speed. Upon impact, precast concrete barriers partially lift the stray vehicle off the pavement, which decreases the lateral resistance force between tires and pavement. Precast barriers can be installed in permanent or temporary applications.

    What are the advantages of having corrugation in crash barriers?

    The layout of corrugated beam barriers ;is that the beams are corrugated in the longitudinal direction so that it provides higher lateral stiffness with a thinner material. Moreover, the distance between beams posts and crashing vehicles are considerably increased.

    In case the beam barriers are tensioned, it is intended to create a stiff beam erected on relatively weak posts. During vehicle collision, the posts would be separated from the beams and there would be lesser deceleration experienced by the vehicles.

    Guardrail Offset Blocks and Associated Products

    Features and Benefits

    Environmentally safe and eco-friendly, Mondo guardrail blocks ;are made from post-consumer/post-industrial material diverted from the solid waste landfill.

    All guardrail blocks are recyclable; there are no disposal costs for damaged blocks because they can be collected, returned, and recycled.

The round end terminal makes the guardrail an elegant appearance, which has high intensity and is easy to install. W-beam fish end guardrail fixed on the bridge to protect pedestrian safety. Fish end terminals possess high-quality impact resistance.

    Square Head Bolts

    Square head bolts ;are used in applications where visibility is limited but durable fastening is required. These bolts have large, flat sides and are easy to tighten with a wrench. Square heads are best used in tight or dark spaces where a machinist or fabricator must tighten the bolt blind. It is simple to fit a tool over the square shape even when there are no visual markers available.

    Steel Grade 5 Square Head Bolts

    Grade 5 medium-strength square head bolts are used in applications where visibility is limited but durable fastening is required. These bolts have large, flat sides and are easy to tighten machinery and equipment with a wrench. Grade 5 steel hex head screws are marked with three radial lines. Square heads are best used in tight or dark spaces where a machinist or fabricator must tighten the bolt blind. It is simple to fit a tool over the square shape even when there are no visual markers available. These bolts come in a black oxide finish, which is corrosion resistant in dry environments, or are zinc-yellow coated for corrosion resistance in wet environments.

    Anchor bolt

    Anchor bolts ;are used to connect structural and non-structural elements to concrete. The connection can be made by a variety of different components: anchor bolts (also named fasteners), steel plates, or stiffeners. Anchor bolts transfer different types of load: tension forces and shear forces.

    A connection between structural elements can be represented by steel columns attached to a reinforced concrete foundation. A common cause of a non-structural element attached to a structural one is the connection between a facade system and a reinforced concrete wall.


    A cast-in-place anchor bolt

    The simplest – and strongest – form of anchor bolt is cast-in-place, with its embedded end consisting of a standard hexagonal head bolt and washer, 90-bend, or some sort of forged or welded flange (see also stud welding). The last is used in concrete-steel composite structures as shear connectors. Other uses include anchoring machines to poured concrete floors and buildings to their concrete foundations. Various typically disposable aids, mainly of plastic, are produced to secure and align cast-in-place anchors prior to concrete placement. Moreover, their position must also be coordinated with the reinforcement layout. Different types of cast-in-place anchors might be distinguished:

    For all the types of cast-in-place anchors, the load-transfer mechanism is the mechanical interlock, i.e. the embedded part of the anchors in concrete transfers and the applied load (axial or shear) via bearing pressure at the contact zone. At failure conditions, the level of bearing pressure can be higher than 10 times the concrete compressive strength, if a pure tension force is transferred. Cast-in-place type anchors are also utilized in masonry applications, placed in wet mortar joints during the laying of brick and cast blocks (CMUs).


    Post-installed anchors can be installed in any position of hardened concrete after a drilling operation.[3] A distinction is made according to their principle of operation.

    A wedge anchor

    The force-transfer mechanism is based on a friction mechanical interlock guaranteed by expansion forces. They can be furtherly divided into two categories:

    Undercut anchors

    The force-transfer mechanism is based on a mechanical interlock. A special drilling operation allows the creation of a contact surface between the anchor head and the hole's wall where bearing stresses are exchanged.

    Bonded anchors ;

    The force-transfer mechanism is based on bond stresses provided by binding organic materials. Both ribbed bars and threaded rods can be used and a change of the local bond mechanism can be appreciated experimentally. In ribbed bars, the resistance is prevalently due to the shear behavior of concrete between the ribs whereas for threaded rods friction prevails (see also anchorage in reinforced concrete).[9] Bonded anchors are also referred to as adhesive anchors[ or chemical anchors. The anchoring material is an adhesive (also called mortar) usually consisting of epoxy, polyester, or vinyl ester resins. The performance of this anchor's types in terms of 'load-bearing capacity, especially under tension loads, is strictly related to the cleaning condition of the hole. Experimental results showed that the reduction of the capacity is up to 60%. The same applies also to the moisture condition of the concrete, for wet concrete the reduction is 20% using polyester resin. Other issues are represented by high-temperature behavior and creep response.

    Screw anchors

    The force-transfer mechanism of the screw anchor is based on concentrated pressure exchange between the screw and concrete through the pitches.

    Plastic anchors

    Their force-transfer mechanism is similar to mechanical expansion anchors. A torque moment is applied to a screw that is inserted in a plastic sleeve. As the torque is applied the plastic expands the sleeve against the sides of the hole acting as an expansion force.

    Powder-actuated anchors

    They act by transferring the forces via mechanical interlock. This fastening technology is used in steel-to-steel connections, for instance, to connect cold-formed profiles. A screw is inserted into the base material via a gas-actuated gas gun. The driving energy is usually provided by firing a combustible propellant in powder form. The fastener's insertion provokes the plastic deformation of the base material which accommodates the fastener's head where the force transfer takes place

Robot Vacuum Cleaner
A robotic vacuum cleaner ;sometimes called a Robovac or a Roomba as a generic trademark, is an autonomous robotic vacuum cleaner that has a limited vacuum floor cleaning system combined with sensors and robotic drives with programmable controllers and cleaning routines. Early designs included manual operation via remote control and a "self-drive" mode which allowed the machine to clean autonomously without human control. Some designs use spinning brushes to reach tight corners, and some include a number of cleaning features along with the vacuuming feature (mopping, UV sterilization, etc.). More recent models use artificial intelligence and deep learning for better mapping, object identification, and event-based cleaning.

    Marketing materials for robotic vacuums frequently cite low noise, ease of use, and autonomous cleaning as the main advantages. The perception that these devices are set-and-forget solutions is widespread but not always correct. Robotic vacuums are usually smaller than traditional upright vacuums and weigh significantly less than even the lightest canister models. However, a downside to a robotic vacuum cleaner is that it takes an extended amount of time to vacuum an area due to its size. They are also relatively expensive, and replacement parts and batteries can contribute significantly to their operating cost.


    Window Vacuum Cleaners - How to Choose One?

    Window vacuum cleaners ;are types of wet vacuums that are used for cleaning windows, tiles, shower doors, car windows, countertops, and similar, flat surfaces.

    Window vacuums are mostly small and compact handheld units, featuring a squeegee (rubber blade), a vacuum motor for creating suction, and a dirt liquid tank. Depending on the model, they can also feature a detergent tank with spray, microfiber pad, and similar.


    Manual Squeegee vs Window Vacuum Cleaner

    Squeegee is a window cleaning tool that is basically a rubber blade on the handle. As the squeegee traverses the window surface, a rubber blade is pressed onto the glass, removing practically all water/liquids from the glass surfaces, leaving the surface clean and shiny, without marks and streaks. The problem is the removal of that water from the rubber blade itself. Some squeegees also feature a sponge/microfiber pad to help remove excess water, but they have to be squeezed periodically.

    Window vacuums also feature rubber blades like manual squeegees, but the blade is combined with a vacuum motor that creates suction, removing all the liquids that are collected by the rubber blade.

    Note: both manual squeegees and window vacuums can have blades made from other materials like foam or plastic, but the rubber blades are most common as they are both flexible and firm.

    Because of all these features, manual squeegees are lighter and cheaper than window vacuums, but window vacuums generally do their job easier and faster.


    Personal care

    What is personal care?

    Personal care ;is the support and supervision of daily personal living tasks and private hygiene and toileting, along with dressing and maintaining your personal appearance.

    The options for personal care

    Like all forms of care, support with personal care is built completely around your individual needs and personal routines. If you like to wash before breakfast or have a bath before going to bed, a carer will happily follow your schedule, letting you live the way you want.

    With home care, you have the choice of having a visiting carer – someone who visits at set times of the day or even overnight – to provide the support you need. If you require ongoing support, it may be best to have a live-in carer, living at home with you to provide 24-hour care. Read more about what live-in care covers here.

    Many carers support with other tasks in addition to personal care. In fact, they’re also trained to administer medication, help those with limited mobility to move safely around the home (especially using hoists and supports), and can prepare meals, complete household chores, and even offer companionship, ongoing support, and encouragement.


    What is a Water Flosser?

    A water flosser ;is an oral health appliance designed for dental care at home. If you don't like string floss, don't floss often, or find string floss hard to use, a water flosser can be the answer. Many people find water flossing easier and more pleasant than using string floss, and they may floss more often as a result.

    Gum disease prevention and treatment is another reason to use a water flosser. Water Flossers are clinically proven to reduce gingivitis, remove plaque, and improve gum health. Water flossers are especially useful for cleaning braces and other orthodontics, as well as cleaning bridges, crowns, and dental implants. Water flossers are helpful for people with dexterity issues, such as arthritis, who find string flossing difficult.


    What is an Oral Irrigator, and Should You Buy One?

    As we've discussed previously, there are five visible sides to your teeth. Simply brushing your teeth takes care of the front, back, and chewing surfaces, but how do you clean between your teeth? That’s right, by flossing. Flossing prior to brushing removes food debris and allows the toothpaste in between the teeth. However, using floss is no longer the only way to get it done.

    A high-tech solution to a low-tech problem has emerged. Oral irrigator, water pick, water flosser, air flosser. It goes by many names, but it is more or less the same. An oral irrigator is a device with a small nozzle that will shoot water, air, or a combination of both at your teeth and gum line in order to remove plaque and food debris. A 2009 study showed that oral irrigators are very good at removing plaque biofilm from teeth, so there seems to be a compelling argument for getting one. Let's take a closer look at the pros and cons.



    It can be very hard to thoroughly brush your teeth when you have braces, as anyone who has had them can testify. It is harder still, if not impossible, to effectively floss between your teeth when you have braces. Because an oral irrigator is just a stream of water and not a piece of nylon thread, it can help clean between the teeth as well as the brackets of the braces.

    Gingivitis is a mild gum disease caused by plaque where the gums become red, shiny, swollen, and bleed easily. Studies have shown that oral irrigators are more effective at treating gingivitis than flossing, which may be due to the irrigators' ability to work underneath the gum line and provide a more complete clean all the way around the tooth.


    The only real downside to oral irrigators is the price. With most units costing somewhere between $100 and $250, it can be a significant outlay for some people.


    What is an Autonomous Mobile Robot – AMR? ; ;

    Autonomous Mobile Robots, also known as AMR robots, are Mobile Robots that Autonomously navigate with natural feature navigation methods. They are trendy and they are opening new robotics applications thanks to their cutting-edge technology. AMR with 3D LiDAR mapping the environment for navigation

    What does Mobile Robot mean?

    AMRs perform “free” or Natural Feature Navigation, so navigation without the need for hardware installation such as wires, tapes, reflectors. It means that the AMR is not “bonded” to any guide. Before having Natural Navigation, we only had Automated Guided Vehicles (AGVs). AGVs navigate by performing different navigation technologies, for example following a magnetic tape on the floor or triangulating position and movement thanks to a laser navigation technology. These technologies need some kind of hardware or device in the working area to allow correct navigation.

    Autonomous Mobile Robots instead, do not need anything to navigate because they identify and map the surrounding area. They “see” walls, columns, shelves, everything and they perform navigation and positioning with this info.


    Automatic Pet Feeder

    An automatic pet feeder ;is provided for feeding pets a predetermined quantity of food or medication at predetermined times while the owner is absent or otherwise engaged. The pet feeder comprises a base, a feeding bowl with pie-shaped divisions, a timer module, a bowl cover, a handle to a bowl cover and a locking mechanism to hold the entire unit in place. A timer is provided with a voice recording facility and also initiates programmed feeding schedules. The programming of the timer determines when the feeder cover is indexed so that the pet may have access to the food provided in it. ;

Digital Multimeter
What is a Digital Multimeter? Basic information and explanation of how digital multimeters differ from analog testers

    Digital multimeters are measuring instruments that can measure quantities such as voltage, current, and resistance. Measured values are shown on a digital display, allowing them to be read easily and directly, even by first-time users. Some digital multimeters select the measurement range automatically, eliminating the need to choose it manually. Consequently, these instruments are comparatively easy to use, even for beginners. Naturally, analog testers also offer advantages, for example in terms of the ease with which changes in the measured value during measurement can be read and the intuitive ease with which a needle can be viewed in locations where a digital reading might be difficult to see. Since both digital multimeters and analog testers have advantages, you can choose the instrument that’s best for your application by clarifying what you wish to measure.

    How to Use Your Digital Clamp Meter

    Digital clamp meters ;are great tools, whether you're an experienced professional or an amateur who’s just starting out. We think that everyone should have one in their toolbox.

    Inside the hard jaws of your new digital clamp meter is ferrite iron. This is what measures the magnetic field of a current as it flows through a conductor.

    A current transformer senses the fluctuations in the magnetic field and converts the value to an AC reading, which shows up on your display. Clamp meters are great for high AC currents, which make them an ideal tool to have around. If you're familiar with how direct currents work, you might wonder how a clamp meter would help you in a situation when you need to measure DC currents instead of AC. Clamp meters that can measure DC current use the Hall Effect to give you a correct measurement.

    However, digital clamp meters aren't limited to just AC/DC current measurements. Your purchase may have included extra sensors to make the tool even more versatile.

    If that's the case, you can plug test leads into your clamp meter to analyze things like voltage. Here's the best part — unlike old-fashioned test probes, you can use a clamp meter to get a current reading without breaking a circuit. No shutting off circuits, no cutting into wires — just clamp the meter around a wire and get your reading. Safe and convenient.

    What is a non-contact voltage tester?

    A non-contact voltage tester pen ;is an electrical tester that helps to detect the presence of voltage. Voltage presence is useful information to have when troubleshooting or working on a failed asset. The first tool you'll reach for is a non-contact voltage detector.

    How do non-contact voltage testers work?

    Non-contact voltage testers work by sensing a very small amount of current that is capacitively coupled from the live circuit to the tester and back to the ground. Non-contact voltage tester pens light up when they detect this current without needing to make direct contact. ;

    A built-in sensor at the tip of the tester detects the presence of voltage when touching a conductor, outlet, or supply cord. By holding the tool, you are the ground reference through capacitive coupling. When the tip glows red and the unit beeps, you know voltage is present.

    How to use a non-contact voltage tester

    To use a non-contact voltage tester pen you only need to touch the tip of the tester to the wire or, if you're testing an outlet, the tip of the tester needs to be placed on the faceplate of a smaller plug slot. Most testers will light up and/or make a sound to confirm voltage is present. In the Fluke 1AC II Non-Contact Voltage Tester, the tip glows red and a beeper sounds when voltage is detected.

    What Is a Socket Tester?

    A socket tester ;is a portable electrical instrument used to test for correct operation and wiring standards on power outlet sockets. It is typically a hand-held instrument that either plugs directly into the socket with pins mounted on the tester or come equipped with a short lead and plug. Depending on the sophistication of the socket tester, a range of status indications may be returned including disconnected phases, reversed phases, and, in the case of a top-end instrument, earth loop impedance. Most testers display test results on an array of light-emitting diodes (LEDs), and some also allow for an earth leakage test to be carried out with the push of a button. Socket testers are available for most common industrial and domestic voltages and pin configurations.

    Sound level meter

    A sound level meter (also called sound pressure level meter (SPL)) is used for acoustic measurements. It is commonly a hand-held instrument with a microphone. The best type of microphone for sound level meters is the condenser microphone, which combines precision with stability and reliability. The diaphragm of the microphone responds to changes in air pressure caused by sound waves. That is why the instrument is sometimes referred to as a sound pressure level meter (SPL). ;

    Sound level meters are commonly used in noise pollution studies for the quantification of different kinds of noise, especially for industrial, environmental, mining, and aircraft noise. The current international standard that specifies sound level meter functionality and performances is the IEC 61672-1:2013. However, the reading from a sound level meter does not correlate well to human-perceived loudness, which is better measured by a loudness meter. Specific loudness is a compressive nonlinearity and varies at certain levels and at certain frequencies. ;

    Radiation Detection
    Radiation detectors ;and monitoring systems are essential for the detection and monitoring of ionizing radiation (alpha particles, beta particles, gamma rays, and X-rays) and neutrons. These systems are typically based on either direct or indirect (scintillation-based) methods of detecting radiation.

    Direct detection relies on the detector absorbing radiation by itself. The direct method gives better energy resolution than the indirect, but the available detectors are limited in size and can’t be used for large portal systems installed at border patrol locations, for example.

    Indirect detection relies on a scintillator converting the radiation to visible light for the detector to detect. Detectors used in the indirect method vary in size from small to large, so they can be integrated into systems ranging from pocket-sized personal monitors to much larger portal monitors. They also offer high sensitivity and are typically lower in cost.

    DC Power Supplies Information

    DC power supplies ;are power supplies that produce an output DC voltage. Power supplies are devices that deliver electric power to one or several loads. They generate the output power by converting an input signal into an output signal (in this case, a DC output).


    DC power supplies are categorized by the mechanism used to convert and transfer the input power to the output power. There are three main categories:

    Linear power supplies accept AC inputs and provide one or more DC outputs for a wide variety of computer and industrial applications. They use an active element (normally a power transistor) operating in its linear region to generate the desired voltage. The output voltage is regulated by dropping excess input power in ohmic losses (heat) in a series dissipative component (resistor) or a transistor. Linear power supplies provide excellent regulation, very small ripple, and very little output noise.

    Switching power supplies use a switching element or regulator (normally a power transistor) to generate the desired voltage. They are also called switch-mode products or switching mode power supplies (SMPSs). These power supplies incorporate electronic components that continuously switch ON and OFF at a very high frequency. This switching action connects and disconnects energy-storing devices (inductors or capacitors) to and from the input source voltage or the output load. An SMPS design results in high power density (smaller size for the same power output) and reduced power consumption (higher efficiency) in comparison to linear power supplies.

    SCR power supplies use silicon-controlled rectifier (SCR) topology to provide well-regulated voltage and current output. Silicon-controlled rectifiers are four-layer thyristors with an input control terminal, an output terminal, and a cathode or terminal that is common to both the input and output terminals. An SCR circuit is commonly used in applications involving high voltages and currents.
