Abstract: A one-piece housing for a rectangular battery cell with circuitry disposed on its side is described. The top side of the housing is a protective ledge, covering only the circuitry disposed on the side of the battery cell, where the ledge lies in or below the imaginary plane formed by the top surface of the cell. The housing protects the battery circuitry, is easier to manufacture than a two-part housing, is lighter than a two-part housing, and has a lower profile.

Abstract: A hinge apparatus rotatably couples about an axis of rotation (303) a body portion (101) and a flip element (103) of a foldable radiotelephone (100). The hinge apparatus includes a hinge shaft (205) having an unlatched and latched position on the axis of rotation (303) relative to the body portion (101). The hinge shaft (205) may be removably latched to a front housing portion (231) of the body portion (101) wherein the hinge apparatus may be tested before final assembly of the foldable radiotelephone (100). The hinge shaft (205), accessible through a slot (245) in the body portion (101), may be removably latched from the outside of the body portion (101).

Abstract: A wireless communication device (20) provides a matching state between a radio circuit (28) and an antenna assembly (26) in both its retracted and extended positions, and does so with an elegant design that increases reliability and manufacturability by reducing the number and complexity of components and moving mechanical parts. A matching circuit (30), which is reconfigured according to a switch (32) that is responsive to the antenna's position, provides the matching states. Furthermore, the switch (32) can be integrally formed as part of a feed terminal (36), the feed terminal (36) and a ground terminal (38) can hold the antenna in position, and the ground terminal (38) can hold a guiding tube (52).

Abstract: A battery charger (100) includes a charging pocket (112) capable of receiving either a first battery (102) in a first orientation or a second battery (104) in a second orientation. The charging pocket (112) includes a first set of contacts (170) and a second set of contacts (152). The contacts (172-175) of the first set of contacts (170) have a first spacing so as to mate with contacts (187) disposed on the first battery (102) when the first battery (102) is inserted into the charging pocket (112). The contacts (154-157) of the second set of contacts (152) have a second spacing so as to mate with contacts (199) disposed on the second battery (104) when the second battery (104) is inserted into the charging pocket (112). By providing two sets of contacts (170, 152) in a single charging pocket (112), the battery charger (100) can charge batteries (102, 104) having dissimilarly positioned contacts.

Abstract: A latching mechanism (160) disposed on an accessory (102) for attaching the accessory (102) to a portable device (100) includes a support (164) and a latch (162) disposed about opposite ends (150, 152) that mate with first and second portions (206 and 300, 302) of a retaining device (123) disposed about opposite ends (112, 122) of the portable device (100). The support (164) includes feet (412, 414) having prongs (420) that face a hooked end (404) of the latch (162). The latch (162) includes a spring (502, 510) coupled to the hooked end (404) such that when the latch (162) is extended, the hooked end (404) exerts a force (700) on the first portion (206) of the retaining device (123) drawing the support (164) into abutment with the second portion (300, 302) of the retaining device (123). The exerted force (700), which is in a plane parallel to a front surface (146) of the accessory (102) extending between the ends (150, 152) thereof, maintains the accessory (102) in attachment with the portable device (100).

Abstract: A support base for a display monitor provides for the stable orientation of the monitor over a range of tilt angles. An upper portion of the base includes a concave surface adapted to receive a complementary convex lower portion of the display monitor's cabinet. The concave surface of the base includes a pair of spaced, upraised, parallel, elongated, lateral guide rails adapted to receive and engage respective guide rail assemblies positioned on the convex lower portion of the monitor. The convex lower portion of the cabinet is further provided with a center projection for insertion within an elongated center aperture in the concave support surface positioned between the paired guide rails. The center projection is coupled to the base by means of a stretchable element such as an extension spring for applying a moment to the monitor tending to rotate it in a first direction within the concave surface.

Abstract: An ultra-compact projection television receiver is disclosed comprising in combination cabinet means for enclosing the receiver components including a vertically reciprocable, rear projection viewing screen selectively storable in the cabinet. Precision elevating means provides for raising and lowering the screen between a stored position in the cabinet and a receiver-operable viewing wherein the screen is emerged. A television system has an ON control mode for providing television sound and pictures and an OFF control mode. Control means coupled to the elevating means and the television system provide for sensing the position of the screen in its reciprocation, and obstructions to said reciprocation manifested by increased resistance to said reciprocation, and correlatively controlling the elevating means and the OFF/ON control modes of the television system in response thereto.
