His work primarily focuses on enhancing the efficiency and accuracy of devices under test.

Latest Patents

Uematsu's latest patents include a test apparatus designed to test a device under test. This apparatus features a clock recovering section that recovers a clock signal from the output signal of the device. It also includes an acquiring section that captures the output signal at a timing corresponding to the clock signal. Additionally, an adjusting section is present to modify the phase difference between the clock signal and the output signal based on a supplied adjustment amount. The setting memory stores these adjustments in association with various test conditions, allowing for precise testing.

Another patent involves a test apparatus that tests a device with multiple data terminals and a clock output terminal. This apparatus incorporates several first variable delay circuits to delay a reference clock and timing clock generating sections that output a timing clock with a designated phase shift. A timing comparator acquires data signals based on the timing clock, while second variable delay circuits and phase comparators further refine the process. The first and second adjusting sections ensure that the timing comparator accurately acquires data signals based on both the timing clock and the clock signal.
