    摘要: Display apparatus comprises a display screen (400) and a drive circuit (401) connected to the display screen (400) to generate an image on the display screen (400) in response to an input video signal (R,G,B). A timer (405) generates a count in response to a clock signal. A detector (403,404,402) also receives the input video signal and resets the timer (405) on detection of a change in image content between successive frames of the input video signal (R,G,B). Control means (402) is connected to the timer (405) and to the drive circuit (401) for at least partially disabling the drive circuit (401) in response to the count stored in the timer (405) exceeding a predetermined threshold.

    摘要: An interposer probe includes a main board having a first side and a second side. A lower riser board mounted to the first side of the main board and in electrical contact therewith is configured to engage an integrated circuit socket on a device to be tested. An upper riser board mounted to the second side of said main board and in electrical contact therewith, is configured to receive an integrated circuit package. A retention frame mounted to the first side of said main board engages the integrated circuit socket on the device to be tested.
