Abstract: A method (200) of assembling a mobile communications unit (120). The method (200) includes the steps of producing (212) a universal base component (118) at an assembly facility (110) and shipping (214) the universal base component (118) to a separate facility in which the separate facility contains a selection of user interfaces (122). The user interfaces (122) are used to initiate a feature in the mobile communications unit (120), and the selection of user interfaces (122) includes user interfaces (122) associated with different customers (114). The method (200) also includes selecting (216) a user interface (122) from the selection of user interfaces (122) and incorporating (218) the selected user interface (122) into the universal base component (118) at the separate facility.

Abstract: A latch (16) for latching or locking a battery housing (14) to a portable radio housing (12) automatically locks into place when it is placed in the radio, and automatically ejects the battery housing when it is unlocked. The latch is movable from a first position, in which the battery housing is locked to the portable radio, to a second position, in which the battery housing is unlocked from the radio, and movable from the second position to the first position. The latch comprises a spring biasing apparatus (18) for attaching the latch to the housing, retainer apparatus (22) for locking the battery housing to the radio, and a spring finger member (20) for ejecting the battery housing from the radio housing when the latch is moved from the first to the second position.

Abstract: An apparatus for mounting a noise cancelling microphone (34) within a communication device comprises a housing having a front portion (36), a back portion and side portions (40). The front portion (36) and one of the side portions (40) have apertures (38 and 40). Within the housing lies a receptacle (32 or 50 or 100) for retaining a microphone or transducer (34). The receptacle is arranged and constructed to form a chamber (32) between the apertures (38 and 40) in the front portion (36) and the side portion (40) of the housing.

Abstract: A slide switch (10) comprises a housing (12) having at least one cantilever beam (22 and 23) integrally formed in the housing (12). A keypad (24 and 25) is arranged and constructed below at least one of the cantilever beams (22 and 23). A horizontal slide actuator (30) is arranged and constructed to slide over the cantilever beam (22 and 23) for substantially biasing the cantilever beam (22 and 23) toward the keypad (24 and 25).

Abstract: An RF interconnect assembly includes a ground plane (124) and a radio circuit (109), and an RF connector (126) having a signal conductor (127) and a ground conductor (130) where the ground conductor (130) is coupled to the ground plane (124). Located a predetermined distance (d) above the ground plane (124), a spring contact (140) provides a constant impedance transmission line connection between the RF connector (126) and the radio circuit (109).

Abstract: An environmentally sealed battery connector (100) includes a battery contact member (102) having a battery contact location (108). Battery connector (100) also includes a resilient seal member (118) having a battery mating ridge (110) which compresses against battery (204) and environmentally seals the point of contact between battery (204) and battery contact location (108).

Abstract: A spring clip arrangement is disclosed for a portable battery powered device which provides an efficient chassis retention feature for a slideably removable electrical chassis in unassociated housing. This retention is accomplished without machine screws and no special tools required. This spring clip arrangement also serves as the electrical contact interface for the associated battery power source insertable in a provided battery compartment.
