Abstract: A finger placement detection unit 51 detects whether or not a finger is placed on a fingerprint sensor. A finger area detection unit 52 computes area of a finger placed on the fingerprint sensor based on the finger placement detection result for small divided regions of the fingerprint sensor. A finger position detection unit 53 computes a position of the finger on the fingerprint sensor based on the detection result in the finger placement detection unit for the small divided regions of the fingerprint sensor. A finger release detection unit 54 detects whether or not the finger placed on the fingerprint sensor is released and outputs the respective results to a control information generation unit 50. Based on the output results, the control information generation unit 50 generates control information such as accelerator control information, handle control information, brake control information, etc. and outputs it to a game program.

Abstract: A semiconductor device test board solves a problem with conventional test boards in that test results obtained through a burn-in procedure could be identified only before the test board is taken out of a burn-in oven. Hence, conventional test boards required additional steps for checking the test results after removing the test boards from the burn-in oven. This extra step prevents the efficiency of the test from being improved. One embodiment of the present test board has indicator arms, each rotatably mounted on a pivot on the test board, for indicating, in response to a signal on a signal line, the test result of the semiconductor device associated with it. Each of the indicator arms maintains its rest position when no failure has occurred in the semiconductor device associated with it during the test.

Abstract: A test circuit includes a writing unit that outputs m-bit data captured upon receipt of a clock signal, branches the m-bit data n identical m-bit data signals, and stores the n m-bit data signals in a memory device. A function determining unit reads the n m-bit data signals from the memory, compares one of the n m-bit data signals to an m-bit expected value, and determines coincidence or non-coincidence between the n m-bit data signal and an expected value.

Abstract: A semiconductor device capable of solving a problem of a conventional semiconductor device in that a high density integration cannot be expected because each cell, which includes a pair of N and P wells disposed adjacently, requires a countermeasure against latchup individually. The high density integration prevents an effective countermeasure against latchup. The present semiconductor device arranges two cells, which are adjacent in the direction of an alignment of the N wells and P wells, in opposite directions so that two P wells (or two N wells) of the two adjacent cells are disposed successively, and includes an isolation layer extending across the two adjacent cells to enclose the two successively disposed P wells, thereby isolating the two P wells collectively from the substrate.
