  • Patent number: 8006146
    Abstract: Provided is a test apparatus for testing a plurality of devices under test, the test apparatus including: a data supplying section that concurrently supplies test data to the plurality of devices under test; a writing control section that controls the test data to be concurrently written to the plurality of devices under test; and a reading control section that successively reads the test data from each of the plurality of devices under test. The plurality of devices under test may be a plurality of memories under test.
    Type: Grant

  • Patent number: 7233872
    Abstract: The error of a sensor in motion capture system is corrected. An acceleration sensor determines the direction of gravity (G1) in a still initial state. The direction G1 will never change always if a drift dose not occur. However, actually if an object to which an acceleration sensor is attached moves along a coordinate axis, the direction gradually changes due to a drift with time. According to the invention, after a given time has passed, the acceleration sensor is stopped to determine the direction of gravity. Referring to the data on this determination, the true direction of gravity to be judged is compared with the direction of gravity G1 influenced by the drift. The difference between them is assumed to be an error due to a drift, and the error is subtracted from the determined value to correct the error of the measurement value.
