  • Publication number: 20120105091
    Abstract: Disclosed herein is an FPGA board assembly for inspecting a semiconductor, the FPGA board assembly being a programmable logic device (PLD) board for inspecting a semiconductor product design, comprising: one or more FPGA boards, each including an FPGA chip provided with a logic circuit for inspecting a semiconductor and a plurality of connectors for inputting/outputting signals; and a switching board including connectors corresponding to the connectors and selectively connecting signals between the FPGA boards, wherein the one or more FPGA boards and the switching board are connected with each other in the form of a laminate by their respective connectors to inspect a semiconductor product design. The FPGA board assembly is advantageous in that boards can be easily connected with each other and in that various problems, such as difficulties of wiring design, the spatial restriction and the like, can be solved.

  • Publication number: 20090051651
    Abstract: Problem: since a remote pointing system using an image sensor and having a communication function through an infrared remote controller is used in various environments, the various environments have to be considered when designing the system. Solution: a signal reception unit outputs a control signal controlled to operate in a mode that corresponds to an infrared signal received from a remote controller among a remote control mode and a remote pointing mode. When receiving a control signal controlled to operate in the remote pointing mode from the signal reception unit, an image reception unit is operated to obtain a background image during a first signal reception section and obtains an optical image that corresponds to an infrared signal received from the remote controller during a second signal reception section. The infrared signal is not received during the first signal reception section and received during the second signal reception section from the remote controller.
