  • Patent number: 11624771
    Abstract: The present disclosure provides an apparatus for illumination inspection of micro LEDs. An apparatus for illumination inspection of micro LEDs includes a surface-contact probe making a surface contact, through an electrical resistive material, with a front surface of an LED assembly of multiple micro LEDs arranged forwardly and interconnecting LED electrodes at both ends of the micro LEDs, probe electrodes to be in line contact with one side and the other side of the surface-contact probe for supplying electric power, an imaging unit for photographing the LED assembly from an opposite surface of the surface-contact probe, to where the surface-contact probe is contacted, and a control unit for supplying electric power to the probe electrodes forwardly along the micro LEDs as aligned and for inspecting the micro LEDs illumination based on images of the LED assembly photographed by the imaging unit before and after supplying the electric power.

  • Publication number: 20110202163
    Abstract: Provided is a plant protection system, which determines initiation of protective actions for the plant, and more particularly to the plant protection system including four channels which controls systems that shut down the plant or mitigate consequences of abnormal conditions of the plant by detecting non-permissible plant conditions with the result of bistable logic comparing process parameters with their setpoints assigned to each channel. Accordingly, common mode failure and cyber security vulnerability caused by software are removed since the system is composed of FPGA and other types of hardware without central processing units and software in determining the initiation of plant protective actions.

  • Patent number: 7991134
    Abstract: An intelligent telephone set is disclosed that includes a caller-ID circuit that extracts a call identifier from an incoming call. A call processing circuit in communication with the caller-ID circuit assigns the incoming call to a caller category associated with the call identifier. Subsequently, it selects a call processing action corresponding to the caller category and processes the incoming call using the selected call processing action. The intelligent telephone set allows users to set criteria for receiving and processing calls based on CID data. One such call processing action is to use CID data to forward an incoming call to a predetermined location.
