Abstract: The present invention provides an electric card fastener with elastic metal cantilever, configured to a circuit board, for fastening an electric card. The electric card fastener is formed by a corresponding mounted base. The mounted base includes a cantilever with a restricted portion disposed along and a mounted portion on the button, connecting with one end of the cantilever. After the connection of the cantilever and the mounted portion, the cantilever is elastic for backward and forward movement. Whereby, the electric card fastener fastens the electric card in a predetermined position for preventing poor electrical connection and strengthening the construction of components of the present invention for improving support ability, and the fastening components are used as a short cut for the grounding circuit on the electric card to connect ground.

Abstract: The present invention provides an electric card fixture for fastening the electric card. The electric card fixture comprises a base having an opening and a pivot member, pivotally connecting to one end of the base. By the base on the circuit board, the electric card is restricted by the opening of the base to a predetermined position. Therefore, the electric card is positioned. The pivot member presses the electric card, so that the electric card will not flip upward. Accordingly, the electric card fixture locks up the electric card, so that the electric card will not fall off when shaken and therefore provides prefect electrical connection.

Abstract: A system for monitoring semiconductor testing tools comprises a tester testing a semiconductor device, whereby a test result is derived, a storage device storing a logic function corresponding to the semiconductor device, and a processor receiving the test result and the logic function from the tester and storage device respectively, and applying the logic function to the test result for validation.

Abstract: Within both an electrical test apparatus for electrically testing a substrate, and a method for electrically testing the substrate while employing the electrical test apparatus, there is provided for an automatic selection of an electrical test program, absent operator intervention, once having identified a substrate. Due to the absence of operator intervention, the substrate is more accurately electrically tested.

Abstract: An automatic charging system for charging nickel-metal-hydride batteries is presented. The battery charging system uses a method of detecting the lowest charge current to control its charging process. The system has a constant voltage power supply including a short-circuit protection device, a battery voltage detector, a current detector, a current to voltage converter, a voltage amplifier, an analog to digital converter, a single chip microcomputer, a capacity indicator, a time indicator and a full-charge indicator. The system uses a constant voltage to charge batteries with a floating current according to the quantity of the active ions in the batteries. The battery charge current is converted to a voltage signal which is then amplified and digitized. The microcomputer detects the digitized signal to estimate the magnitude of the charge current.
