    Abstract: A taut armature reciprocating impulse transducer (100) which typically provides a non-linear hardening spring response is adapted to provide a non-linear softening spring response by the addition of magnetic damping elements (106). Two or more taut armature reciprocating impulse transducers (100) can be utilized to produce a mechanical acoustic crossover network (700) which operates to produce a wide frequency response when at least one of the two taut armature reciprocating impulse transducers (100) is adapted to provide a non-linear softening spring response. The mechanical acoustic crossover network (700) allows multiple taut armature reciprocating impulse transducers (100) to be operated together from a signal input. When the mechanical acoustic crossover network (700) is enclosed in a housing (812), the mechanical acoustic crossover network (700) can be operated as a headphone to deliver an audio output.

    Abstract: A mode tracking transducer driver (100) for a non-linear electromagnetic transducer (102) includes a voltage controlled oscillator (104) coupled within a phase lock loop to a transducer driver (106) and a mode detector (112, 108). The voltage controlled oscillator (104) generates a variable frequency output signal, and is responsive to a frequency control signal for controlling the frequency of the output signal. The transducer driver (106) generates a transducer drive signal (502) which is coupled to the non-linear electromagnetic transducer (102) to generate a tactile alert. The mode detector (112, 108) detects a mode change between at least the first operating mode and the second operating mode of the non-linear electromagnetic transducer (102), and in response thereto generates the frequency control signal (118) which establishes a quasi-resonant frequency (204) at which the tactile energy delivered by the non-linear electromagnetic transducer (102) is maximized.

    Abstract: A molded thermoplastic housing (100) includes base (102) and cover (104) members joined by a living hinge (106). The base member (102) includes a peripheral wall (108). Four solderable printed circuit patterns (112, 114, 116 and 118) are vacuum deposited onto the interior and exterior surfaces of both housing members. The printed circuit patterns on opposing surfaces of the base and cover members are joined by conductive through-holes (e.g., 120 and 122), while the printed circuit patterns on the interior surfaces of the base and cover members are joined by an interconnecting printed circuit pattern (124) which is vacuum deposited onto the living hinge. Mylar sheets (132) are adhered to the exterior surface of the housing to insulate the exterior printed circuit patterns. An antenna pattern (126) is also vacuum deposited onto an exterior surface of the housing. A switch (136) and battery contact (152) are integrally formed with the housing and an integrally molded structural support means strenghthens the housing members. The housing is manufactured "opened up" and, at the final assembly stage, the cover member is rotated about the hinge until it contacts the upper surface of the peripheral wall (108B). Snap-fit connectors (e.g., 110) join the cover to the base.

    Abstract: A communication receiver (10) including a display (22) having a predetermined number of displayable characters, a decoder (14) for receiving and processing data messages, a plurality of control switches (20) for operating the decoder (14), and a memory (16) for storing a plurality of received data messages. The decoder (14) selects a data message to display from the memory (16), arranges the data message into a plurality of screens, computes an individual variable screen timeout value for each screen, and displays each screen on the display (22) in a predetermined order for the screen timeout value computed. The screen timeout value computed on the basis of the message content of the screen, the presence of control characters in the data message, or the generation of input signals from the control switches (20). The screens can be displayed in a forward direction or a reverse direction. Each direction can either be at a fast or a slow rate.

    Abstract: An assembly for a pager having a main housing that is generic to a family of pagers having different outputs. A subassembly housing contains the output circuitry for each member of the family of pagers. A generic circuit is mounted on a circuit board that is slideable within the main housing between a first and second position. The circuit board, in a first position, allows the subassembly housing to mate with the main housing. The subassembly housing is locked into mated engagement with the main housing when the circuit board is slid from its first position to its second position. The locking engagement is provided by a tongue-like projection mounted on the circuit board which is received by a slot in the subassembly housing when the circuit board slides to its second position. In conjunction with this a flange mounted on the subassembly housing engages a first end of the circuit board.
