  • Portable radio battery latch
    Patent number: 5620242
    Abstract: A latch (202) for a battery (10) includes a beam (2) supported at opposite springing (418) ends (8). A protrusion (52) located between the opposite ends of the beam selectively latches onto a fixed hook (152).
    Type: Grant
    Filed: April 19, 1993
    Date of Patent: April 15, 1997
    Assignee: Motorola, Inc.
    Inventors: Robert Leon, Kok H. Chong, Kuruvilla Valakuzhy
  • Apparatus for RF shielding radio circuitry
    Patent number: 5596487
    Abstract: First and second shielding portions (110, 112) formed of electroless plated plastic enclose a radio frequency (RF) board (108). Bosses (148) extend from inner surfaces (130, 142) of the first and second shielding portions (110, 112) to make contact with compressible ground clip members (126) located on the RF board (108).

  • Integrated battery contact and retentive protrusion
    Patent number: 5457376
    Abstract: A battery (10) includes at least one cell (71) which is contained in a housing (16). Mating mechanisms, located on the housing, selectively attach the battery to the radio. The mating mechanisms include a protrusion (36) selectively receivable (64) by the radio. For electrical coupling, at least one electrical contact (18) is located on the protrusion (36).

  • Electronic assembly incorporating a three-dimensional circuit board
    Patent number: 5424921
    Abstract: An electronic assembly (100) includes a first circuit board (120) which houses electronic components (122), a second circuit board (140) being three-dimensional and having integral members (143) to receive and position the first circuit board (120), and an electrical connector (130) between the first circuit board (120) and the second circuit board (140).

  • Door cover assembly
    Patent number: 5316168
    Abstract: A detachable self-contained door cover assembly (105) includes a housing (101) with an integral socket (160), a hinge member (140) having a rotation track (153), and a door cover (120) having an integral hinge shaft (123). The hinge shaft (123) engages the rotation track (153) to rotatably couple the door cover (120) to the hinge member (140) about an axis of rotation extending through the hinge shaft (123) and the rotation track (153). The hinge member (140) is attached to the socket (160), and is detachable when a force exceeding a threshold value is applied to the hinge member (140), thereby disengaging the hinge member (140) from the socket (160) without substantial damage to the hinge member (140) or to the housing (101).
