Abstract: A low pass filter circuit (600) for a radiotelephone which filters harmonic, spectral components of a modulated signal generated by the radiotelephone. The filter circuit is comprised of inductors and capacitors (602, 660) wherein each inductor and each capacitor of the filter is comprised of a distributed-element portion (604, 666) and a discrete element portion (616, 618, 664). The distributed element portions of each inductor and each capacitor of the filter attenuate higher-frequency, spectral components of a signal applied thereto. The discrete element components of each inductor and each capacitor of the filter attenuate lower-frequency, spectral components of the signal applied thereto.

Abstract: A vehicle route guidance system considers driver preferences, vehicle parameters such as speed and performance capabilities in a navigation computer, and outputs flexible guidance instructions based on these considerations. The system monitors vehicle parameters such as current location and speed with sensors such as an odometer (109), a compass (115), and a GPS receiver (113). The system also determines the location of a vehicle manoeuvre and then, considering the former attributes with a model free mechanism, in this case a navigation computer with fuzzy inferencing (101), communicates to the driver instructing him how to manoeuvre.

Abstract: A ceramic dielectric block filter is manufactured by forming a block of uncured dielectric material that includes a plurality of holes formed there through which extend through the dielectric block to intersect top and bottom surfaces of the dielectric block (10), curing the dielectric block by sintering it (10), coating exterior surfaces of the cured dielectric block and surfaces within the holes by at least partially immersing the dielectric block into a viscous, thixotropic electrically conductive liquid (20), heating the dielectric block to dry the electrically conductive liquid (40), and at least locally removing from the top surface of the dielectric block electrically conductive material surrounding at least one hole (50).

Abstract: In an exemplary embodiment, a communication device, such as a radiotelephone (100), has within its housing (106) an apparatus for electrically coupling an electroacoustic transducer (201), such as an earpiece, to ratiotelephone circuitry. The apparatus comprises resilient conductive means, for example conductive barrel springs (213-216), abutting both the conductive contacts on the earpiece (241, 243) and the corresponding conductive contacts on a printed circuit substrate (205, 208 and 206, 207). A bracket (211) manually attached to the printed circuit substrate (203) positions the conductive barrel springs (213-216) while they are compressed between the earpiece (201) and the printed circuit substrate (203) during the assembly of the radiotelephone (100). A plurality of barrel springs (213-216) are used to provide redundant electrical coupling and stability for the earpiece (201). The apparatus advantageously provides for improved manufacturability and convenient replaceability of the earpiece (201).

Abstract: A unique cellular telephone (500) includes audio circuit (502), microcomputer (508), indicators (506 and 507), cellular telephone transceiver (519), and keypad controller (504) for controlling the operating modes thereof and automatically placing and receiving cellular telephone calls dialed in any pattern. The keypad includes numerical keys (0-9, # and *) and function keys (MEM and END/CLEAR) for entering digits of telephone number and key sequences for selecting operating modes. Power is applied to the cellular telephone transceiver (519) in response to concurrent activation of at least two keys. Each telephone number digit is detected and accumulated by microcomputer (508) and, after a pause of four seconds, the accumulated digits are sent via a data bus (511) to cellular telephone transceiver (519) for placing a telephone call. The call is subsequently terminated when the END key is activated or an END command is received by the cellular telephone transceiver (519). Thereafter, power to the cellular telephone transceiver (519) may be turned off in response to activation of the MEM-END key sequence.

Abstract: A Viterbi equalizer (366) for decoding a π/4 DQPSK modulated signal. Because symbol values of adjacent symbols of a π/4 DQPSK signal are offset in phase relative to one another, allowable values of succeeding states of a π/4 DQPSK signal are four in number. The signal paths of the Viterbi equalizer are thereby limited in number to four allowable next-states (600) and the Viterbi equalizer (366) is operative to select certain ones of the paths connecting the states at the adjacent time intervals as survivor paths to form maximum likelihood paths thereby.

Abstract: A simulcast transmission system (10) provides for time synchronizing data transmissions from a plurality of transmission stations (16, 18). The transmission stations (16, 18) include transmission clocks (36) for controlling the time of transmission of synchronization timing signals and data, the synchronization timing signals indicating a local time of transmission which are transmitted in response to system timing signals received from a control station (12). The control station (12) comprises apparatus (20) for generating and distributing the system timing signals, apparatus (26) for receiving the synchronization timing signals from the transmission stations, and apparatus (20, 22, 28) for generating and distributing time adjustment factor signals to the transmission stations (16, 18) in response to receiving the synchronization timing signals. The transmission clocks (36) are adjusted in response to the time adjustment factor signals for controlling the time of transmission of the data signals.

Abstract: Communication between first (38, 40 or 42) and second (38, 40 or 42) portable radiotelephone transceivers is provided in a radiotelephone communication system by generating a paging message (500-512) in response to the first transceiver (38, 40 or 42) registering with a first telepoint base station (32, 34 or 36). The paging message (500-512) is directed to the second transceiver (38, 40 or 42) for which communication is requested, and identifies the first telepoint base station (32, 34 or 36) and the first transceiver (38, 40 or 42). Upon receiving the paging message (500-512), the second transceiver (38, 40 or 42) registers with a second telepoint base station (32, 34 or 36), downloading the information identifying the first telepoint base station (32, 34 or 36) and the first transceiver (38, 40 or 42). The second telepoint base station (32, 34 or 36) establishes communication with the first telepoint base station (32, 34 or 36), after which the first telepoint base station (32, 34 or 36) requests registration of the first transceiver (38, 40 or 42) to complete the communication between first (38, 40 or 42) and second (38, 40 or 42) transceivers.

Abstract: In a radio transceiver (100), an IF stage (110) is formed on a single substrate. A balanced or image rejection mixer (204) having two pairs of inputs and a pair of outputs is integrated on an IC substrate (202). Disposed on the IC substrate are SAW transformers (210, 212 and 214) which provide a desired phase transformation. The SAW transformers comprise piezoelectric layers (228) and metallization layers (230) which are suitably patterned to provide the desired phase transformation and frequency selectivity.

Abstract: A unique process metallizes a substrate surface using a reducing agent including a borohydride to reduce, in a starved reaction, metal oxide particles (300) substantially uniformly distributed and at a controlled concentration in a particle-filled resin (204) to produce catalytic island areas (301). The catalytic island areas (301) formed have a surface resistivity greater than 106 ohms per square. These catalytic island areas (301) are then electrolessly metallized to a predetermined thickness, such that adjacent catalytic island areas (301) are interconnected and form metallic features, such as pads, vias (213), and conductors (210, 211 and 212). The starved reaction limits the reduction of metal oxide particles (300) to catalytic island areas (301) and prevents migration of reduced metal beyond each of the exposed surfaces of particle-filled resin (204) which are to be metallized.
