  • Patent number: 8228384
    Abstract: The invention discloses a circuit testing apparatus for testing a device under test. The circuit testing apparatus includes a filtering circuit, an amplifying circuit, a comparing module, and a result-examining module. The filtering circuit filters an analog output signal generated from the device under test to generate a filtered signal. The amplifying circuit amplifies the filtered signal to generate an amplified signal. The comparing module compares the amplified signal with at least one reference level to generate at least one result signal accordingly. The result-examining module examines the result signal to determine a test result for the device under test.

  • Patent number: 8209818
    Abstract: A handle unit includes a handle, a connector, a bolt, a latch, a button and a spring. The handle includes two lugs. The connector includes a lug. The lug of the connector is located between the lugs of the handle. The bolt is inserted in the lugs so that the handle is pivotally connected to the connector. The latch is connected to the bolt and located in a non-circular opening of the second lug of the handle. The button is connected to the bolt. The spring is compressed between the button and the first lug of the handle to make the latch partially enter a non-circular opening of the connector to position the connector relative to the handle. The button can be pressed to make the latch leave the non-circular opening of the connector.

  • Publication number: 20110260415
    Abstract: A tool includes a chuck connected to a handle. The chuck includes a mandrel including a non-circular cavity defined therein, a slit in communication with the non-circular cavity, a first bore in communication with the non-circular cavity, and a second bore in communication with the slit. A bit with a non-circular profile can be inserted in the non-circular cavity. A flat bit can be inserted in the slit. A ball is located in the first bore. A pin is located in the second bore. A movable sleeve is movably rotationally located around the mandrel and formed with a thread. A rotary sleeve is rotationally located around the mandrel and formed with a thread engaged with the thread of the movable sleeve. By rotating the rotary sleeve, the movable sleeve pushes the ball into the non-circular cavity and the pin into the slit.

  • Patent number: 7882769
    Abstract: An insulating screwdriver includes a handle, a drive shank having a first end mounted in the handle and a second end protruding outwardly from the handle, an insulating jacket mounted on the second end of the drive shank, and an identification insulating sleeve mounted between the second end of the drive shank and the insulating jacket. Thus, when the insulating jacket is worn out or broken due to friction or hit, the identification insulating sleeve is still located outside of the drive shank to provide a secondary insulating effect to the drive shank so as to protect the user when operating the drive shank.

  • Publication number: 20110025243
    Abstract: A robust method for detecting a relative position of a feedback device, such as an encoder or resolver, coupled to a shaft, such as a motor shaft, is provided. To detect the relative position, electrical commands are issued in an open loop mode to spin the motor shaft an amount greater than the apparent rotational angle between two consecutive markers of the position feedback device, such that the net mechanical rotation is equal to or greater than the total rotational angle between two consecutive markers.
