  • Patent number: 7484981
    Abstract: A submersible electrical connector assembly (300) includes an electrical connector (301) mounted to a first substrate (309) where a second substrate (311) adjoins the first substrate (309). The second substrate (311) is comprised of a pliable material that acts as a seal. The first substrate and second substrate are positioned within a compartmentalized area of an electrical device housing for preventing water or other fluid from entering an aperture within the housing. Although water may inadvertently enter the electrical connector (301), the connector assembly (300) is substantially submersible since water is prevented from entering the housing (400) as used for an electronic device.

  • Patent number: 7249861
    Abstract: A keypad assembly (100) for a communication device (200) utilizes two boards, a main circuit board (102) with electronic components including light emitting diodes (LEDs) (104) and a keypad board (108). A lightguide (106) is sandwiched between the two boards (102, 108), the lightguide having window protrusions (112) to accommodate the LEDs (104). The keypad board (108) has openings (116) within which the window protrusions (112) align in order to provide backlighting and sealing to the communication device (200).

  • Patent number: 6787695
    Abstract: A shield (100) having an outer surface (104) and a plurality of sidewalls (106) is disclosed. The plurality of sidewalls (106) extends from the outer surface (104). At least a portion of the plurality of sidewalls (106) are designed to retain the shield to at least a portion of a substrate (102). Further, at least a portion of the plurality of sidewalls (106) are designed to deflect away from the substrate (102) when pressure is applied to the outer surface (104) in such a manner that the outer surface (104) assumes a concave position (202).

  • Patent number: 6305540
    Abstract: A holster (100) includes an adjustable depth pocket (101) for receiving at least a portion of a portable radio (102) in the pocket (101). The portable radio (102) includes an interface, such as a user interface (120, 122), and the holster (100) includes access openings (124, 126). An adjustable false bottom (130) in the pocket (101) is adjustable to provide a variable depth in the pocket (101). When the portable radio (102) is received in the pocket (101) the user interface (120, 122) and the access openings (124, 126) are substantially aligned thereby the user interface (120, 122) is accessible from outside the holster (100) via the access openings (124, 126).

  • Patent number: 6225777
    Abstract: A latching mechanism is provided. The latching mechanism includes a first member (2) having a first catch (4) and lateral catches (6), and a second member (1) having a notch (7) and lateral catches (8). In a first position, the first catch of the first member engages the notch of the second member. In a second position, the lateral catches of the first member engage the lateral catches of the second member. Further, when in the first position, the first catch and the notch are disengaged by squeezing one of the members at lateral points while sliding the members relative to one another until the lateral catches are engaged and the members are in the second position. Also provided is a battery pack (1, 2) having such a latching mechanism. Additionally, there is provided an electronic device that includes an operational unit (3), a tray (2) for holding battery cells, and a cover (1). The tray is removably coupled to the operational unit, and the cover is removably coupled to the tray.
