The second mode of operation provides a personal organizer when the flap (104) is in a open position.

Abstract: A rotary control device is provided comprising a light receptor (52), a plurality of light sources (54) radially spaced from the light receptor (52), a light director (14) having means for directing light from the light source (54) to the receptor (52) and means for rotating the director (14) thereby selectively directing light from the light sources (54) to the light receptor (52). In another aspect of the invention, the optical rotary device further comprises an isolator (56) made of opaque material which surrounds four sides of the light receptor (52) and four sides of the light sources (54). In a further aspect of the invention the light director includes a reflector (46) for directing the light from the light sources (54) to the light receptor (52).

Abstract: Briefly, according to the invention, there is provided a shielded speaker. The speaker (10) has a diaphragm (18) coated with a metal layer (28). The coated diaphragm prevents the transmission of unwanted electromagnetic or radio frequency radiation from the front side (22) of the speaker to the rear side (24) of the speaker. In an alternate embodiment of the invention, a shielded electronic device is provided. The device consists of a housing (40) that has an opening (42) for a speaker (10) and a shielding means (44) contained within the housing. The speaker has a diaphragm coated with a metal layer. Disposed within the housing is an electronic device that is susceptible to or emits electromagnetic radiation. The electronic device (46) is coupled to the speaker and the speaker is mounted in the housing such that the metal layer is electrically coupled (48) to the shielding means.

Abstract: A rotary control device is provided comprising a light source (22), at least one light receptor (24) radially spaced from the light source (22), a light director (14) having means for directing light from the light source (22) to the receptor (24) and means for rotating the director (14) so that the light director (14) is in a first position when not directing light from the light source (22) to the light receptor (24) and the light director (14) is in a second position when directing light from the light source (22) to the light receptor (24). In another aspect of the invention, the optical rotary device further comprises an isolator (26) made of opaque material which surrounds four sides of the light receptor (24) and four sides of the light source (22). In a further aspect of the invention the light director includes a reflector (46) for directing the light from the light source (22) to the light receptors (24).

Abstract: An optical rotary control device (10) is provided comprising a light source (12) and at least one light receptor (14) linearly spaced, creating a planar axis with the light source (12). A rotatable light director (16) is provided which includes means for directing light from the light source (12) to at least one optical aperture (22) in the light director (16). The optical aperture (22) refracts the directed light from the light director (16) to the light receptor (14). The optical rotary control (10) device further comprises an isolator portion (20) having recesses (24) for receiving and separating the light source (12) and light receptor (14). The means for directing light may include a cut out section (18) in one end of the light director (16 ).

Abstract: 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.

Abstract: A switch (10) comprises a rotary part (12, 14, 16 and 18) and a bracket (24) for supporting the rotary part. The rotary part comprises a knob (12), a shaft (14), attached to, or formed on, the knob, a detent cam (16) attached to, or formed on, the shaft, and a light director (18), attached to the shaft, for directing light from an external light source to a light receiver when the switch is in a first position and for directing light from the light source away from the light receiver when the switch is in a second position. The bracket comprises a detent spring (17) for making contact with the detent cam to provide operating positions for the switch.

Abstract: The electrical assembly of the present invention comprises an integrally molded member which includes at least one three dimensional connector. Electrical printed circuitry are disposed on the integrally molded member, wherein portions of the printed circuitry comprise electrical contacts of the connector. Electrical components are placed on the integrally molded member and are electrically interconnected via the printed circuitry.

Abstract: An integral electrical interconnection is made between two circuit carrying substrates (100 and 110). The first circuit carrying substrate (100) contains one or more protrusions (102) on the peripheral edge of the substrate (100) which couples to a series of one or more apertures (104) on the peripheral edge of a second circuit carrying substrate (110). Both the tabs and the apertures are covered with conductive materials (202 and 210) also connected to the circuit.

Abstract: The present invention provides for a battery pack (50) comprising a plurality of cells (58) within a housing (52), each cell having a positive and negative terminals (57 and 59). The battery pack (50) further comprises molded-in circuitry means (54) on the surface of the housing (52) for providing interconnection between the plurality of cells (58). Optionally, the housing (52) further comprises molded-in or integral spring fingers (56). The spring fingers (56) are preferably biased toward the positive and negative terminals and provide at least some interconnection for the plurality of cells (58).
