  • Publication number: 20060291171
    Abstract: According to embodiments of the present invention, an optical transponder module generates heat when operating and a heat pipe disposed in the module body performs active heat transfer from a hot end of the optical transponder module to a cooler end of the optical transponder module. A heat pipe disposed in an external clip-in heat sink may remove heat from the optical transponder body.

  • Publication number: 20060285806
    Abstract: According to embodiments of the present invention, an optical transponder module generates heat when operating and at least a copper heat wick and/or a copper block are disposed in the module body to perform passive transfer of heat from inside the optical transponder module to outside the optical transponder module. The heat wick may be soldered to thermal vias in the printed circuit board that is internal to the optical transponder module and positioned over the laser transmitter circuitry. The copper block may be positioned in a cutout in the optical transponder module body to acts as a heat spreader. Thermal grease, compounds, paste, interface material, etc., may be used to help the conduction of heat.

  • Publication number: 20050209602
    Abstract: A method and apparatus for fluidly coupling a reservoir containing a flowable biomaterial to a mold. The flow of the flowable biomaterial into the mold is controlled in accordance with a first operating parameter. At least one injection condition is monitored. The flow of the flowable biomaterial is controlled in accordance with a second operating parameter in response to one or more of the injection conditions reaching a threshold level. The second operating parameter is maintained during at least a portion of the curing of the flowable biomaterial. In some embodiments, the second operating parameter may optionally include permitting a portion of the flowable biomaterial to be expelled from the mold.

  • Patent number: 6663634
    Abstract: A bone fastener which prevents infection that can be used, for example, to attach an external fixation device to bone. The fastener may be partially coated with an antibacterial agent (such as silver) directly deposited on the biocompatible material to prevent infection. The coating can be applied to the fastener in a number of different ways in a wide variety of patterns.

  • Publication number: 20020029043
    Abstract: The present invention relates to a bone pin or screw that can be used, for example, to attach an external fixation device to a bone. The bone pin is made of a biocompatible material and includes a first portion located at a distal end of the pin and having a threaded section for insertion into the bone, a second portion located at a proximal end of the pin, and a third portion located between the first and second portions. The third portion is at least partially coated with an antibacterial agent (such as silver) directly deposited on the biocompatible material to prevent infection. The coating can be applied to the bone pin in a number of different ways in a wide variety of patterns.
