Abstract: An apparatus for detecting the surface profile of a test object includes a light source, a beam splitter, a reflective component, a sensor, and a computing device. The light source emits a light beam. The beam splitter divides the light beam into reference and probing beams. The reference beam is reflected by the reflective component back to the beam splitter. The reflective component is configured so that components of the reflected reference beam travel at different optical path lengths to the beam splitter. The probing beam is reflected by the test object back to the beam splitter. The beam splitter combines the reflected reference and probing beams to result in a heterodyne light beam. The sensor converts the heterodyne light beam into a corresponding electrical signal. The computing device records the converted electrical signal. A method for detecting the surface profile of the test object is also disclosed.

Accordingly, analog-to-digital converters can be replaced for faster sampling. The measuring method and system can be implemented using comparator circuits or pin electronics cards so that the measuring procedure for driver chips is simplified. Measured results are analyzed and verified by application of probability and statistics. As such, testing of liquid crystal display driver chips is more accurate, testing time is reduced, and accuracy level is promoted.

Abstract: A modular AC/DC power conversion module for power sources and loads and a method of driving the same is provided. When an AC/DC converter is electrically coupled to an external power source, a microprocessor is electrically energized by a buck auxiliary circuit, under control of the microprocessor, a DC/DC converter is activated for a certain time period, and then, the AC/DC converter is activated. Thereafter, an output voltage of the AC/DC converter is boosted, and an output voltage of the DC/DC converter is boosted accordingly. Power elements in the downstream side DC/DC converter are activated first, and then power elements in the upstream side AC/DC converter are activated, thereby an inrush current is suppressed. Once the external power source is connected, the buck auxiliary circuit will automatically reduce a voltage of the power input to activate the module. It realizes that the module will autonomously operate after being electrically energized.

Abstract: The present invention relates to a chip transfer device capable of floatingly positioning a chip and a method for floatingly positioning a chip. When a chip is placed in a chip socket, a control unit controls an air pressure switching valve to allow at least one vent hole to be communicated with a positive air pressure source. An air flow from the positive air pressure source blows a lower surface of the chip through the vent hole, so that the at least one chip is air-floated. Accordingly, when the chip socket is communicated with the positive air pressure source, the air flow blows the lower surface of the chip in the chip socket through the vent hole, so that the chip is air-floated in the chip socket to reduce the error displacement of the chip offset.
