  • Patent number: 5336984
    Abstract: The electronic device powering system enables a battery powered device to power another device needing power while also powering itself. The accessory power connector (102) makes a connection before breaking it by a spring contact (110) that is more flexible in one end (111) than the other (112). This allows the less flexible end (112) to force the internal power connector (104) in the electronic device to break its connection.

  • Patent number: 5243355
    Abstract: An antenna apparatus for a radiotelephone (100) comprises a shroud (207), an antenna (209) and releasable latch means (231, 219, 223, 229). The shroud (207) is movable between a first and a second position. The antenna is an extendable helical coil (209) having a shortened axial length when the shroud is moved to the first position and a lengthened axial length when the shroud is moved to the second position. The extendable helical coil (209) exerts biasing forces on the shroud (207) when the shroud is moved to the second position to urge the shroud (207) towards the first position.

  • Patent number: 5151643
    Abstract: A charging apparatus for a multiunit system includes a portable unit (101) and a base unit (103). The portable unit (101) includes first and second conductive contacts (119, 120) disposed on the portable unit (101) essentially opposite each other, and rechargable energy storage means (311) electrically coupled to the first and second conductive contacts (119, 120). The base unit (103) includes an indentation (124) formed in the base unit (103) and having a receiving surface shaped to receive at least a portion of the portable unit (101), first and second conductive protrusions (127, 129) extending outwardly beyond the receiving surface essentially opposite each other, and energy source means (131) electrically coupled to the first and second conductive protrusions (127, 129). The first and second conductive protrusions (127, 129) contact the first and a second conductive contacts (119, 120), respectively when at least a portion of the portable unit (101) is placed in the indentation (124).

  • Patent number: 5117073
    Abstract: A hinge actuated switch apparatus initiates a control signal responsive to the rotational movement of a flip element (103) on a radiotelephone unit (100). The radiotelephone unit's circuitry senses of whether the flip element (103) is in a closed or open position. The integrated miniature switch comprises a pin (223) attached eccentrically to one end of a hinge (221) on the flip element (103). As the flip element (103) is rotated, the pin (223) drives a push rod (203) to compress a conductive elastomeric pad (205) thereby electrically connecting normally open conductive circuit pads (234 and 236), on the surface of a printed circuit board (201).

  • Patent number: 5028083
    Abstract: A latch assembly for maintaining a battery in position upon a portable telephone. The latch assembly includes a latch body having at least one face surface forming a latching surface for abuttingly engaging with the battery to maintain the battery in position. A spring member exerts a spring force for maintaining the latch body and, hence, the latching surface formed thereupon in the abutting relationship with the battery. A downward force exerted upon the latch body causes translation thereof to remove the latching surface from the abutting engagement with the battery.

  • Patent number: 4963812
    Abstract: A battery charger for charging batteries of varying sizes is disclosed. Batteries to be charged are inserted into a recess in the battery charger housing and are captivated by a lip portion which extends into the recess. The lip portion has a plurality of surfaces, one of which surfaces contacts a surface of a battery of one size and maintains the position of the battery against the charging contacts of the battery charger. Different size batteries contact different lip surfaces.

  • Patent number: 4746242
    Abstract: Unique flex-lock dovetail mounting apparatus (300) is described that may be advantageously utilized for mounting radio transceivers (100) and accessories (200) in harsh environments. The housing of the radio transceiver (100) includes on one side thereof at least two channels (101 and 105) producing a dovetail. The mounting apparatus (300) includes a top plate (304); a slide plate (308) attached to the top plate (304), having on at least one end a cut-out portion (310) producing a gap (320, 321 and 322) between the cut-out portion (310) and the top plate (304), and having at least two rails (301 and 305) producing a dovetail and each adapted to insert into a corresponding one of the channels (101 and 105); and locking apparatus including a lever (306) or a thumb screw (706) coupled to the top plate (304) and the cut-out portion (310) of the slide plate (308) for flexing the cut-out portion (310) toward the top plate (304) thereby locking the rails (301 and 305) in position in the channels (101 and 105).

  • Patent number: 4711361
    Abstract: A housing having sides interlocking at the corners is disclosed in which covers are provided inwardly curved edges having a G-shaped cross-section which slideably mate with a curved edge and inside slot of a side structured member of the housing. Upon fastening, a volume is created within the mated joints to captivate chips and burrs generated by the fastening process.

  • Patent number: 4440478
    Abstract: A slide tray position sensing arrangement is provided for slide projector apparatus. The slide tray position sensing arrangement is arranged at a detection station. A coded aperture ring is provided that moves in a manner correlated to the movement of a slide tray turntable. The slide tray turntable carries the slide tray that holds the slides for projection and also functions as a tray transport arrangement. The coded aperture ring includes two circumferential arrays of apertures. Each of the apertures in the first array corresponds to a controlled slide position of a first tray type; e.g., an 80 slide tray. Each of the apertures in the second array corresponds to a controlled side position of a second tray type; e.g., a 140 slide tray. The slide tray position sensing arrangement is controllable to selectively sense the appropriate array of apertures corresponding to the slide tray type being utilized.

  • Patent number: 4429963
    Abstract: A slide transfer and shutter control arrangement is provided for a slide projector including a simplified shutter control arrangement and a positive acting slide sensor arm that is slidably mounted for shifting translation. Slide transfer is accomplished by a vertically movable lifter arm operated by a level wind screw. The level wind screw also operates a cam actuator. The cam actuator moves up and down with the lifter arm to actuate a slider member. The slider member controls the position of the slide sensor arm and provides shutter latch control. The slide sensor arm retains the shutter in the closed position when no slide is present and the slider member is actuated by the cam actuator to release the shutter latch. When a slide is sensed by the slide sensor arm, the slide sensor arm releases the shutter for projection of the slide at the slide transfer station. Slide face tension is appropriately provided by a face tension arrangement under the control of the cam actuator.
