摘要:
An uninterruptible power supply (UPS) (100) has a housing (111) that supports the major electrical components of the UPS (100), i.e., a transformer circuit (207), a switching circuit (217), and a battery (209). Furthermore, a connector (107;115;117) affixed to the housing (111 ) is capable of removably affixing the UPS (100) to an alternating-current (AC) outlet (102).

An electronic device such as a radiotelephone (100) includes a bottom housing (108) defining a first hinge aperture (2207) and a slot (2208) adjacent the first hinge aperture. A top housing (102) defines a second hinge aperture (2223) having an inner rotation surface (2226). A shaft (2210) extends from the first housing at the first hinge aperture. The shaft is sized for insertion in the second hinge aperture and terminates in a bearing surface (2216), the inner rotation surface pivoting on the bearing surface as the second housing moves in relation to the first housing. The shaft and the bearing surface both define a shaft slot (2218) aligned with the slot in the first housing for routing a flexible circuit element (216) between the first housing and the second housing.
摘要:
A communication device (10) with a dual-sided liquid crystal display (12) located with a housing (14) having two viewports (18,22). The display (12) includes a liquid crystal panel (50) with an associated driver circuit (52). The panel (50) has a first side (60) for viewing a top portion (62) of the display (12) from the first viewport (18) and a second side (64) for viewing a bottom portion (66) of the display (12) from the second viewport (22). A top reflective layer (68) is disposed on the top portion (62) of the panel (50) on the second side (64) of the panel (50). A bottom reflective layer (70) is disposed on the bottom portion (66) of the panel (50) on the first side (60) of the panel (50). A processor (82) is coupled to the driver circuit (52), wherein the processor (82) directs the display (12) through the driver circuit (52) to provide user interface information for operating the communication device (10). The present invention provides a dual-sided display (12) on a single LCD panel (50) using one driving circuit (52).
摘要:
An antenna assembly (200) for use in a portable radio (100). The antenna assembly (200) includes first and second housings (113 and 203), a helical antenna (301) and a terminal (205). The first housing (113) is telescopically moveable with respect to the second housing (203) between a retracted and an extended position. The helical antenna (301) has a first dimension when the first housing (113) is moved to the first position and a second dimension when the first housing (113) is moved to the second position. The terminal (205) is coupled to the helical antenna (301) for replaceably coupling to the portable radio (100) by a user. Additionally, a pin (303), covered with a thickened solution (304), is disposed within the helical antenna (301)to dampen mechanical vibrations of the helical antenna (301) and a detenting mechanism retains the first housing (113) in the first and the second positions.
摘要:
Apparatus for routing a flexible circuit element (216) between a top housing (102) and a bottom housing (108) in an electronic device such as a radiotelephone (100). The flexible circuit element includes a termination at a tab (2712) off the edge of the flex strip, oriented at an angle from the direction of trace routing. This provides the minimum possible flex width so that the flex may be routed through minimally sized openings, in turn minimizing the size of the electronic device.
摘要:
An keypad comprises at least first and second actuators formed of a substantially translucent elastomeric material. A barrier (103) disposed within the first actuator (200) permits light, emitted by a first light source (105), present inside the first actuator (200) to substantially illuminate at least a portion of the first actuator (200) without substantially illuminating the second actuator (505) and permitting light, emitted by a second light source (503), present outside the first (200) and second (505) actuators, to substantially illuminate at least a portion of the first actuator (200) and at least a portion of the second actuator (505). A method for making a selectively illuminated keypad is also disclosed.
摘要:
A telephonic handset housing assembly for a cordless telephone. The housing assembly comprises a carriage and a clip which is releasably engageable with the carriage. Because the clip is releasably engageable with the carriage, when the handset is not to be carried with an object, the clip may be removed so as not to form a portion of the handset housing assembly.
