  • Publication number: 20070272041
    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.

  • Publication number: 20060245712
    Abstract: Embodiments of the present invention provide devices, systems and methods to test optoelectronic modules. In one embodiment, the testing device can include a printed circuit board (PCB) and a first portion attached to the PCB. A second portion can be attached to the first portion. The second portion can include at least one testing device that can be used to test an optoelectronic module disposed between the first portion and the second portion. The optoelectronic module can be electrically and mechanically connected to at least one of the PCB and the first portion.

  • Publication number: 20060070789
    Abstract: A decorative rotatable accessory includes one or more rotatable decorative elements mounted about a cylindrical vehicle component, such as an automobile exhaust, a motorcycle fork, a head lamp, handle bar, or the like. In one implementation, an assembly comprises an interface that is mounted to the vehicle component. A rotator, which is operably coupled to one or more decorative elements, is coupled to the interface component in such a way that the one or more decorative elements can rotate in response to a wind or air force. In particular, when an air force, such as wind or exhaust pushes against one or more of the decorative elements, or against one or more impeller blades coupled to the decorative elements, the decorative elements rotate, creating a decorative motion effect.

  • Patent number: 7024329
    Abstract: An evaluator board for testing a printed circuit board assembly device subcomponent includes one or more receiving surfaces mounted on the evaluator board, and a securing mechanism positioned over at least one of the one or more receiving surfaces. The receiving surfaces can include a connection base and an electronic receptacle for receiving conductive elements of the subcomponent to be tested. In one implementation, at least one of the one or more receiving surfaces is configured to receive an edge connector of a form factor pluggable printed circuit board. In addition, one or more active and passive circuitry components can be mounted on opposing surfaces of the evaluator board in order to minimize the size and number of components used in the testing of the PCBA subcomponent.

  • Publication number: 20050025449
    Abstract: An assembly and method for testing an optical subassembly by locally heating or cooling the optical subassembly. Locally heating or cooling the optical subassembly can include using a thermal transfer assembly. The thermal transfer assembly can include a thermoelectric cooler. A clamping assembly is provided to place the optical subassembly in electrical communication with a testing assembly. The thermal transfer assembly can be associated with the clamping assembly. After achieving the desired temperature, a data stream is transmitted through the optical subassembly and evaluated for compliance.
