Abstract: Electronic devices, such as mobile communication devices, may include several enhancements and modification not found on traditional electronic devices. Parts of the electronic device can be welded together to provide structural support and or functional connections between operating components of the electronic device. Within a band, a back plate can support multiple operable components of the electronic device. The band, the welds, and/or the back plate can provide electrical connections between components. Conductive pathways provided by the welds can be provided with adequate strength and durability to reduce and avoid breakage so that sensitive components, such as a compass module, can operate without alterations that would cause interference. The welds can be provided in a sequence that mitigates the effects of heating during the welding process.

Abstract: A clamp for a water bottle cage having a mounting plate with spaced apertures comprising a first part having a rear hemispherical cavity, a front face having threaded bores having the same spacing as the apertures on the plate and a rear face having spaced threaded bores receives threaded fasteners for fastening the plate to the clamp. A second part having a front hemispherical cavity and spaced apertures receives threaded fasteners for clamping a water bottle cage to tubing such as the handlebar of a bicycle.

Abstract: A selective call receiver (900) includes a ceramic substrate (820) for conveying an electrical signal. The ceramic substrate (820) has at least one solder pad which includes a solder pad area (110) of an electrical conductor (120) on the ceramic substrate and a solder wettable layer (210). The electrical conductor (120) consists essentially of a conductive ceramic material. The solder wettable layer (210) is attached to the solder pad area (110). The solder wettable layer (210) includes at least 50% indium by weight. A circuit device (410) has at least one circuit terminal which is soldered to the at least one solder pad of the ceramic substrate (820) for electrical interconnection to another circuit device (410) in the selective call receiver (900).

Abstract: A solder pad for mechanically and electrically coupling solder terminals (420) of electronic devices (410) to a non-conductive ceramic substrate (130) includes a solder pad portion (110) of a conductive runner (120) and a solder wettable layer (210). The solder pad portion (110) of the conductive runner (120) is on the non-conductive ceramic substrate (130). The conductive runner (120) consists essentially of a conductive ceramic material. The solder wettable layer (210) is attached to the solder pad portion (110). The solder wettable layer (210) includes at least 50% indium by weight.

Abstract: A conductive adhesive (120) for electrically and mechanically bonding circuit terminals (105) includes a polymer (121) having a predetermined curing temperature range, a first conductive particulate material (125) suspendable in the polymer (121) for providing substantially uniform conductivity throughout the conductive adhesive (120), and a second conductive particulate material (130) suspendable in the polymer (121) for metallurgically bonding together particles of the first particulate material (125). The first conductive particulate material (125) provides substantially uniform conductivity throughout the conductive adhesive (120) and includes metallic particles having a melting point above the curing temperature of the polymer. The second conductive particulate material (130) welds together particles of the first particulate material (125) and includes metallic particles having a melting point within the curing temperature range of the polymer (121).

Abstract: A full color high contrast image projection system with oil coupled dichroics and a single projection lens is disclosed. The invention includes a unitary optical tank in which a prepolarizer and dichroic separators are mounted in fixed alignment relative to a main polarizing prism. The prepolarizer acts on the incident light from a source to polarize the green light and reflect the S component out of the system. The red and blue components are transmitted unchanged. The main polarizer is mounted at a 90.degree. twist relative to the prepolarizer so that it reflects the green light to a first light valve via a first dichroic separator. The polarized red and blue components are transmitted to second and third light valves via a second dichroic separator. The light valves modulate the polarization state of incident light before returning it to the second beamsplitter. The second beamsplitter then recombines the individual beams into a single output beam.
