  • Patent number: 12278424
    Abstract: A method of constructing an antenna of a portable communication device. The method includes wrapping a conductive element around a flexible support, coupling the conductive element and the flexible support to a rigid connector to assemble an antenna core, and coating the antenna core with a room temperature vulcanizing (RTV) silicone layer. The method further includes fitting a first half of a silicone rubber sheath and a second half of a silicone rubber sheath around the antenna core, compression molding the first half of the silicone rubber sheath and the second half of the silicone rubber sheath around the antenna core, and bonding, by the RTV silicone layer, the silicone rubber sheath to the antenna core.

  • Patent number: 7200363
    Abstract: A communication device such as a cellular telephone (200) includes a heat-generating device (206) that generates heat energy. In thermal proximity to the heat-generating device (206) is a scent package (208) that includes a scented substance that is activated by the heat generated by the heat-generating device (206). In one embodiment of the invention, the heat-generating device (206) is a power amplifier. In another embodiment of the invention, a method of providing a scent in a communication device comprises providing a heat-generating device and placing a scent package in thermal proximity to the heat-generating device. The heat-generating device can be a power amplifier used by the communication device, or other electrical circuit found in the communication device.

  • Patent number: 5397408
    Abstract: A method for ultrasonically welding two plastic parts together. One part (30) has a weld joint feature (23) that is covered with a metal layer (27), and the other plastic part (25) has a complimentary weld joint feature. The two parts are joined together by ultrasonically welding the two weld joint features to each other. A force (40) is applied to the first and second plastic parts prior to the step of welding. The force is substantially in excess of that required to cause the two weld joint features to contact each other. This method creates an ultrasonic welded metallized plastic assembly. Each part of the assembly has a weld joint feature, at least one of which was covered with a metal layer prior to welding. Portions of the each of the two weld joint features are deformed to form a plastic weld joint through the metal coating.

  • Patent number: 5173220
    Abstract: A method for producing a three dimensional plastic article having an insert. The three dimensional plastic article (20) is formed by exposing a liquid photopolymer or other material (14) capable of selective solidification or curing to a source of energy (10), preferably a laser beam (30). A portion of the three dimensional plastic article is formed by selectively exposing portions of the surface (12) of the liquid photopolymer to the laser beam. The insert (26) is placed onto the partially formed article (20), and the remainder of the article is formed by selectively exposing additional portions of the surface (16) of the liquid polymer to the laser beam, creating successive layers, whereupon a plurality of the layers form the three dimensional article (20). The insert (26) becomes an integral part of the completed three-dimensional article.
