Patent number: 7200363Abstract: 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.Type: GrantFiled: January 22, 2003Date of Patent: April 3, 2007Assignee: Motorola, Inc.Inventors: Paul M. Greco, Stephen D. Hunt, Joseph W. Seuck

Patent number: 5397408Abstract: 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.Type: GrantFiled: May 23, 1994Date of Patent: March 14, 1995Assignee: Motorola, Inc.Inventors: Andrzej T. Guzik, Stephen D. Hunt

Patent number: 5173220Abstract: 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.Type: GrantFiled: April 26, 1991Date of Patent: December 22, 1992Assignee: Motorola, Inc.Inventors: David E. Reiff, Dale W. Dorinski, Stephen D. Hunt
