  • Patent number: 8586857
    Abstract: A combined diode, lead assembly incorporating two expansion joints. The combined diode, lead assembly incorporating two expansion joints includes a diode having a first diode terminal and a second diode terminal, a first conductor and a second conductor. The first conductor includes a first terminal that is electrically coupled to the diode at the first diode terminal and a second terminal that is configured as a first expansion joint, which is configured to electrically couple to a first interconnecting-conductor and is configured to reduce a stress applied to the diode by the first conductor. The second conductor includes a first terminal that is electrically coupled to the diode at the second diode terminal and a second terminal that is configured as a second expansion joint, which is configured to electrically couple to a second interconnecting-conductor and is configured to reduce a stress applied to the diode by the second conductor.

  • Patent number: 8203200
    Abstract: A leadframe design for a diode or other semiconductor device that reduces stress on the device and provides increased heat dissipation is provided. According to various embodiments, the leadframe has a contoured profile including a recessed area and a raised surface within the recessed area. The surface supports the device such that the edges of the device extend past the surface. Also provided are device assemblies including the novel leadframes. In certain embodiments, the assemblies include one or more leadframes attached via a solder joint to a device. According to various embodiments, the leadframes are attached to the front side of the device, back side of the device or both. In particular embodiments, the device is a bypass diode for one or more solar cells in a solar module.

  • Patent number: 6049290
    Abstract: A pager including a housing and a control button interface, where the housing has an opening having at least one recess area around a portion of the opening and the control button interface is coupled to the housing and has multiple buttons arranged with at least one of the controlled buttons positioned between the other buttons. One of the buttons is located near the one recess area so as to enable its depression without causing other buttons from being depressed.

  • Patent number: 5016969
    Abstract: An optical coupler for coupling light between an optical fiber core and an electrooptic transducer includes a pin and channel arrangement associated with a mechanism for opening and closing the coupler. At one position the pin engages an end of the channel whereat the coupler is open and safe insertion or removal of the fiber from the coupler is possible. At a second position, the pin engages another end of the channel and an optical fiber previously inserted into the coupler when in its open position is securely locked in the optical coupler.
