  • Patent number: 9910079
    Abstract: A grounding resistance measurement apparatus measures a grounding resistance at an AC power terminal, and is electrically connected to an equipment input terminal which provides an AC power source. The grounding resistance measurement apparatus includes a DC power generation circuit and a DC voltage detection circuit. The DC power generation circuit receives the AC power source at the equipment input terminal and converts the AC power source into a DC power source. The DC power source is provided to produce a DC resistance voltage across the grounding resistance. A voltage difference between the equipment input terminal and an equipment grounding point is equal to the DC resistance voltage so that the grounding resistance is calculated according to the zero DC component in an AC power loop.

  • Patent number: 9302593
    Abstract: An electric vehicle supply equipment receives an external AC power source. The electric vehicle supply equipment includes a relay apparatus and a controller. The relay apparatus has a master relay, an auxiliary relay, and a controllable switch. The master relay is connected to a master power loop. The controllable switch is connected in series to the auxiliary relay to form a series path and connected to an auxiliary power loop. When the controller detects the external AC power source, the controller turns on the auxiliary relay. Afterward, when the controller detects that the external AC power source is in a zero-crossing condition, the controller drives the controllable switch to be turned on. Accordingly, the relays are controlled in coordinated timing, and further the external AC power source is detected, thus implementing the zero-voltage and zero-current turning on of the relay apparatus.

  • Publication number: 20160093085
    Abstract: A scanning booth with a user interface. The interface receives user identification or registration data and provides instructional prompts for the user to assume various predefined positions, stances and postures. Image data of each pose is captured using scanning devices in the booth. A three dimensional avatar is generated based on the mapping or morphing of image data to a generic avatar model. Data from the generated model is transmitted to a server where it is stored in a database for later account application in, for example, garment sizing, display or fitting, or health monitoring.

  • Patent number: 9182446
    Abstract: A relay detection apparatus includes at least one relay, a voltage detection module, and a voltage comparison unit. The relay has an input contact, an output normally-open contact, and an output normally-close contact. The voltage detection module has a first voltage detection unit and a second voltage detection unit. The first voltage detection unit receives a voltage of the input contact and produces a first output voltage. The second voltage detection unit receives a voltage of the output normally-close contact and produces a second output voltage. The voltage comparison unit receives the first output voltage and the second output voltage and then compares the two voltages, thus detecting normal and/or abnormal contact statuses of the input contact, the output normally-open contact, and the output normally-close contact of the relay.

    Abstract: A laser scriber with a self-correcting mechanism comprises a laser scribing unit, a detection unit, a control unit and a drive unit. The laser scribing unit scribes a pattern on a solar panel according to a drive signal. The detection unit detects the pattern to generate a correction signal. The control unit corrects a scribing program based on the correction signal. The drive unit generates the above-described drive signal based on the scribing program. A self-correction method of a laser scribing process comprises the steps of: setting a scribing program on a laser scriber; fixing a solar panel to the laser scriber and performing a position calibration procedure; scribing a pattern on the solar panel via the laser scriber based on the scribing program; examining whether the pattern corresponds to a specification or not; and if no, automatically generating a patch program to replace the scribing program.

    Abstract: A backpack has at least one air cushion and a backpack structure. At least one strap is mounted on the backpack structure and the air cushions are mounted onto the strap and backpack structure. The air cushion is mounted with a bladder having an air valve and an inflating device. A person uses the inflating device to add air into the bladder that is then capable of cushioning impacts by the bag and providing a perfect fit to the person. Accordingly, the backpack volume is minimized by pressing the air valve to discard the air and is convenient for storing.
