摘要: In an antenna communications unit which, when installed on trucks, allows two-way communications between a driver and fleet logistic centers, historically, a global positioning system (GPS) antenna within a radome has been housed in a cavity beneath a transceiver's messaging antenna. A method and device is provided which moves the GPS antenna from beneath the messaging antenna and places it in an enclosure mounted to the radome.

摘要: A keyboard or keypad assembly has an outer housing of rigid material with an upper panel having a single opening or plural key receiving openings, and a keypad of resilient material located beneath the upper panel, with keys projecting upwardly from the keypad through the panel. A printed circuit board is positioned in the housing beneath the keypad and is secured to the upper panel with the keypad sandwiched between the panel and circuit board. The keypad has a peripheral rim surrounding the key containing area, and an upwardly facing groove is located in the rim. A corresponding, downwardly projecting rib is provided on the upper panel for seating in the groove to form a moisture seal by compressing the resilient material at the base of the groove, so that spilled liquids cannot enter the area in which the circuit board is located via the openings in the upper panel.
