John C. Dirkson has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 7406247
    Abstract: Devices, systems and methods for thermal testing of optoelectronic modules are disclosed. The device includes a frame member, a thermoelectric cooler, a plate in thermal contact with the DUT, a heat sink in thermal contact with the frame, and a metallic clip for attaching the thermal testing device to the module (DUT). The clip secures the thermoelectric cooler to the DUT. The method includes the steps of providing a testing apparatus having a printed circuit board with a test circuit formed thereon. The test board also has an electrical interface disposed in electrical communication with the test circuit, and a thermal testing assembly. A temporary electrical connection is formed between the DUT device and the interface. The thermal testing assembly is used to maintain a test temperature of the DUT device. A data stream is transmitted through the DUT device and then evaluated for adherence to a defined specification.

  • Patent number: 7378834
    Abstract: An electronic assembly tester for testing an electrical component of an optoelectronic device. The electrical component includes a transmit and receive port. The tester includes of a base, an arm, and a hinge. The arm includes a flex circuit and cables. The arm is rotated into a closed position to form a temporary electrical connection between the electrical component and the flex circuit. Other configurations for forming a temporary electrical connection between the test circuit and the electrical component are possible. The electrical component is evaluated by providing a data signal to the transmit portion of the electrical component and evaluating a return data signal obtained from the receive portion of the electrical component.
