  • Patent number: 6133885
    Abstract: An antenna assembly (118) for a wireless communication device (100) has a non-telescoping antenna (200), a bushing (204) and a post (202). The bushing (204) has an attachment mechanism (238) to secure the bushing (204) to the device (100). The post (202) has two ends. One end of the post (202) is joined to the non-telescoping antenna (200). The other end of the post adapted to electrically connect the non-telescoping antenna (200) to transceiver circuitry (304) of the device (100). The post (202) is journaled in the bushing (204) to permit to permit radial movement of the non-telescoping antenna (200) without unsecuring the bushing (204) from the device (100).

  • Patent number: 5436802
    Abstract: An electronic device employs a method and apparatus for shielding an electrical circuit (101) that is disposed on a substrate (120). A base member (103) that includes a top portion (104) and a plurality of side portions (105) is electrically coupled to a receptacle area (121) of the substrate (120) such that the plurality of side portions (105) substantially encircle the electrical circuit (101). The top portion (104) of the base member (103) includes a plurality of tab members (108) interposed with a plurality of receptacle openings (109). A substantially planar cover (102) that includes a plurality of protrusions (111) is positioned adjacent to the top portion (104) of the base member (103) such that each protrusion (111) is positioned within a corresponding receptacle opening (109). The cover (102) is then urged until each protrusion (111) interlocks with a corresponding tab member (108) to substantially enclose and, thus, shield the electrical circuit (101).

  • Patent number: 5420759
    Abstract: A support assembly, and associated method, for permitting a reduced-sized, card member to be received by a standard-sized, card reader assembly of a radio telephone. The support assembly is comprised of a frame formed of a standard-sized, card member having a through-hole extending therethrough. The through-hole is of dimensions corresponding to the card member of the reduced dimensions. A thin, support sheet covers a portion of an opening formed by the through-hole on a top surface of the frame to form a front joist thereby, and the thin, support sheet is folded about an edge of the frame similarly to form a rear joist over an opening formed upon a bottom face surface of the frame by the through-hole. The front joist and the rear joist together form a pocket for supporting the card member of the reduced dimensions within the through-hole.

  • Patent number: 5257414
    Abstract: The present disclosure includes a discussion of a Subscriber Identification Module (SIM) chip card reader (201). In the preferred embodiment, the SIM chip card reader is integrated into and sealed to a radiotelephone. A battery (105) for the radiotelephone (103) retains the SIM chip card (401) in the SIM chip card reader (201) while the radiotelephone (103) is operating. The SIM chip card reader (201) also includes a ejector knob (405) for removing the SIM chip card (401) from the SIM chip card reader (201).
