摘要:
A portable electronic device includes a display-input apparatus (108) for displaying alternate character sets, in correspondence with a selected mode of operation of the device. The display-input apparatus uses first and second cholesteric display layers (302, 304) to display the different character sets. Each cholesteric display layer displays a different character set when active. When not active, the cholesteric display layer is rendered transparent.

A communication device (100) comprising a body portion (110) and a display portion (130) that is rotatably connected to the body portion. A switch (160,161, 162, 163,164) is operable to reverse the modes of the inner (141) and outer (142) bistable clear-reflective layers in response to rotation of the display portion (130) with respect to the body portion (110).

A hinge assembly (2100) includes a hinge body (2102) made of two hinge body halves (900). Each hinge body half is identical so that only one part need be manufactured, and two of them used to form the hinge body. Each hinge body half has a first leg (902) that is longer than a second leg (904). The first leg has a retaining lip (912) at the end which forms a retaining feature. Each leg of the hinge body defines an axis of rotation for the body elements (104, 106). A portion (1508) of a flexible circuit board (1506) is captured between the hinge body halves so as to electrically interconnect circuitry placed in each body element. A detent mechanism is provided to hold the body element in preselected positions with respect to each other, and includes a spring (2106), a cam (2108) and a cap (2110) having cam follower features (2118). The cam is held in place with respect to the body element housing, while the cap is fixed in position with respect to the hinge body. To stabilize the rotation of the body elements, a hook (2404) retains a collar edge (2402) upon rotation of the respective body element.

A control switch for a radio is formed using an electro-mechanical assembly (400) which includes an array of cantilevered beams (402) laminated with piezoelectric film. A movable surface (404) includes protrusions (406) positioned to deflect the cantilevered beams and generate pulsed signals in a coded manner. Electronic circuitry (410) stores the pulsed signals and associates the signals with a position of the switch.
摘要:
An integrated circuit (106) having an optically erasable portion (114) is joined to a substrate (102) such that the optically erasable portion faces the substrate. The substrate (102) includes an aperture (104) that exposes the optically erasable portion (114) of the integrated circuit providing erasing capability to the integrated circuit (106). A plug (110) impermeable to light may be inserted into the aperture (104) to provide a sealed window to the optically erasable portion (114) of the integrated circuit (106).
摘要:
A vehicular adaptor for a portable communications device, such as a cellular telephone, pager, or two-way radio, is disclosed which includes a connector that aligns itself to a mating connector on the communication device. The connector permits spatial alignment of electrical contacts in the connector with electrical contacts in the communications device. A corrugated spring mounting clamp and a locating nest on the connector permit the alignment of connections.

An integral electric switch, for controlling an electronic apparatus, comprises a main housing and a flap portion, rotatably attached thereto. The main housing contains the electronic apparatus. The flap portion has a hinge cam for rotatably attaching the flap portion to the main housing, so that the flap portion is movable from a defined open position to a closed position with respect to the main body. The main housing comprises a plurality of spring fingers making sliding contact with the hinge cam as the flap portion is rotated from the open position to the closed position thus providing a switching function and electrical connection from the housing to devices contained within the flap.

A control and antenna mount assembly (100) includes an antenna mount portion (130) having a top portion (132) for mating to an antenna (142). Assembly (100) also includes an insert member (122), control knob (110) having selector contact (118) and a retainer ring (120) all connected to antenna mount (130), together forming a rotary switch, concentric to antenna mount (130).
