  • Publication number: 20230231070
    Abstract: An isolation system and isolation device are disclosed. An illustrative isolation device is disclosed to include a transmitter circuit to generate a first current in accordance with a first signal, a first elongated conducting element to generate a magnetic field when the first current flows through the first elongated conducting element, a second elongated conducting element adjacent to the first elongated conducting element so as to receive the magnetic field. The second elongated conducting element is configured to generate an induced current when the magnetic field is received. The receiver circuit is configured to receive the induced current as an input, and configured to generate a reproduced first signal as an output of the receiver circuit.

  • Patent number: 11621364
    Abstract: An isolation system and isolation device are disclosed. An illustrative isolation device is disclosed to include a transmitter circuit, a detector circuit, a first wire bond, and a second wire bond. The detector circuit is configured to generate a first current in accordance with a first signal. The first wire bond is configured to receive the first current from the transmitter circuit to generate a magnetic flux. The second wire bond is configured to receive the magnetic flux. An induced current in the second wire bond is then detected in the detector circuit. The detector circuit is configured to generate a reproduced first signal, as an output of the detector circuit.

  • Publication number: 20130170936
    Abstract: Various embodiments of methods and devices are provided for a self-aligning pick and place collet having proximal and distal ends configured for use with a tape and reel machine. A suction area is located at a distal end of the collet. A pick and place collet contact area is located adjacent to and outwardly from the suction area, and comprises tapered sidewalls that depend downwardly and outwardly away from the outer periphery of the suction area. The tapered sidewalls and the outer periphery of the suction area are configured and dimensioned to cause an electronic device to substantially self-align and center itself with respect to the collet when engaged thereby.
