Abstract:
A picking system comprises a radio frequency identification (RFID) tag, a case, a two-wire conductive strip, at least one identifying unit and a processing unit. The two-wire conductive strip is electrically connected between the identifying unit and the processing unit. The identifying unit reads tag information within the RFID tag for actively and instantly controlling the authorization of an operating staff assigned for particular items thereby improving the accuracy of picking items.
Abstract:
An optical touch system includes a substrate, at least one sensor, a processing unit and an analysis unit. The substrate has a touch region. The at least one sensor is used for capturing a full-size image of the touch region, wherein the full-size image includes a central region image near a light axis of the at least one sensor, and a side region image. The processing unit is used for sampling the central region image to obtain a central compressed image and transmitting the central compressed image and the side region image under a normal mode. The analysis unit is used for analyzing the central compressed image and the side region image to obtain a touch point coordinate.
Abstract:
An embodiment of the disclosure includes a conductive bump on a semiconductor die. A substrate is provided. A bond pad is over the substrate. An under bump metallurgy (UBM) layer is over the bond pad. A copper pillar is over the UBM layer. The copper pillar has a top surface with a first width and sidewalls with a concave shape. A nickel layer having a top surface and a bottom surface is over the top surface of the copper pillar. The bottom surface of the nickel layer has a second width. A ratio of the second width to the first width is between about 0.93 to about 1.07. A solder material is over the top surface of the cap layer.
Abstract:
A communication headset includes a housing having an upper cover defining a pivot hole and a locating hole. An earpiece and an ear hook are disposed on the top of the upper cover. A microphone arm has a raised portion received in the pivot hole. The bottom center of the raised portion defines an aperture. A locating cavity is defined at the bottom of the microphone arm. A pivot frame fixed in the housing defines a receiving can to accept a spring shaft, around which a spring winds for providing a torsion force to the microphone arm. An end of the spring shaft forms a locking portion fixed in the aperture. And a limiting body having a buckling block is mounted in the housing for limiting rotation of the microphone arm which is driven by the torsion force when the buckling block is forced to withdraw from the locating cavity.
Abstract:
An electrical connector assembly includes an insulating housing, a plurality of first contacts received in the insulating housing, at least one detecting pin and a controlling circuitry. At least partial first contacts unitarily includes first contacting portions transferring first data signals and second contacting portions transferring second data signals. The detecting pin produces two sets of different detecting signals corresponding to the first data signals and the second data signals. The controlling circuitry controls said data signals output data signals through different output terminals.
Abstract:
A system for universal serial bus (USB) image capturing with two isochronous transfers includes a USB image capturing device and a host. The USB image capturing device has two endpoints for transferring a video stream through a USB. The host has a driver for receiving the video stream through the USB. The driver receives the video stream, and creates a read extension data structure for the endpoints. The driver manages and dispatches the packets of the endpoints, and copies data of the packets into a first buffer and a second buffer, respectively. When a first end frame flag in a packet of the first endpoint is set and a second end frame flag in a packet of the second endpoint is set, the driver combines data of the first and the second buffers into a frame and sends the frame to the host.
Abstract:
A DC power system is provided to generate the power from renewable energy and directly supplies the DC power to DC household appliances, thus saving energy that would be wasted during the conversion of DC to AC and back to DC and saving the cost of a rectifier or power factor corrector. The DC power system includes a generator, a DC/DC converter, a battery bank, a bi-directional inverter, a DC load and a controller.
Abstract:
This invention relates to use protein-polymer conjugates described in the specification to treat various diseases, including disease is idiopaic myelofibrsis, polycythaemia vera, and essential thromobocythaemia.
Abstract:
A memory cell with surrounding word line structures includes an active area; a plurality of first trenches formed on the active area in a first direction, each first trench has a bit line on a sidewall therein; a plurality of second trenches formed on the active area in a second direction, each second trench has two word lines formed correspondingly on the sidewalls in the second trench; and a plurality of transistors formed on the active area. The word line pairs are arranged into a surrounding word line structure. The transistor is controlled by the bit line and the two word lines, thus improving the speed of the transistor.
Abstract:
An exemplary power supply circuit configured for supply power for a load includes: a main power supply configured for converting received voltages into required direct current voltages; a microprocessor configured for providing control signals; a stand-by control circuit configured for controlling the main power supply; an energy storage circuit configured for supplying the stand-by control circuit. When the load stops operating, the microprocessor outputs a control signal to the stand-by control circuit, the stand-by control circuit outputs a corresponding control signal to turn off the main power supply. In response to when the load starts operating, the stand-by control circuit outputs a corresponding control signal to turn on the main power supply, and the main power supply charges the energy storage circuit.
