Abstract: A communication system (100) is provided for transmitting data to mobile receivers utilizing a subcarrier within a commercial FM channel of a radio station (55). The data transmitted is first encoded in encoder (112), utilizing a forward error correction code. The sequence of the encoded data is altered in interleaver (116), subdivided into a plurality of subframes, in framing and synchronization circuit (120), which also adds channel state bits to each subframe. The framed data is modulated onto the subcarrier in the differential quadrature phased shift keying modulator (130), the output of which is coupled to the FM modulator (52) of radio station transmitter (50). The transmitted radio frequency signals may be received by a vehicle antenna (12) for coupling to the vehicle's FM receiver (80). The modulated subcarrier is recovered from the FM demodulator (84) of the receiver (80), the modulated subcarrier being demodulated to recover the encoded digital data therefrom. The channel state bits included with the data are extracted from the digital data and utilized to form a data reliability factor for each bit of the encoded data. The data reliability factors thus obtained are associated with each bit of the data in a deinterleaver (360). Deinterleaver (360) provides each data bit in proper sequence, with its associated data reliability factor to decoder (370). The decoded digital data is provided to a vehicle traffic computer (90) for processing and presentation of traffic information to a user on a display (92).

Abstract: A single chip microprocessor 1 comprises a CPU 2 and a sub-processor 5 for implementing peripheral functions of the microprocessor 1 by software. The sub-processor 5 includes electrically writable internal storage devices called a microprogram memory unit 13 and a sequence control memory unit 62 for storing the software. Peripheral functions to be implemented by the sub-processor 5 can be defined or modified by writing software into the memory units 13 and 62. Accordingly, the time it takes to define or modify the peripheral functions is the same as the time it takes to program the memory units 13 and 62. 
     The sub-processor 5 also includes an execution unit 16 for executing a plurality of tasks and an address control circuit 14 for providing addresses to the microprogram memory unit 13 in addition to the microprogram memory unit 13 for providing microinstructions to the execution unit 16. The sequence control memory unit 62 is part of the address control circuit 14 which also includes a plurality of address registers MAR0 to MAR11. The sequence control memory unit 62 is used for storing information on what order the multiple address registers MAR0 to MAR11 are to be selected in sequentially. One of the address registers MAR0 to MAR11 is selected at every read cycle performed on the sequence control memory unit 62. A microaddress stored in the selected one of the address registers MAR0 to MAR11 is then supplied to the microprogram memory unit 13. Task null information can also be stored in the sequence control memory unit 62. The selection of one of the address registers MAR0 to MAR11 at every read cycle allows the sub-processor 5 to operate on an event driven basis.

Abstract: A high side current sense amplifier (21) comprises a first resistor, a second resistor, an amplifier (22), and a darlington transistor pair. The first resistor has a first input and a second input coupled to a non-inverting input of the amplifier (22). The darlington transistor pair has a collector coupled to the non-inverting input of the amplifier (22), a base coupled to an output of amplifier (22), an emitter. The second resistor is coupled between the emitter of the darlington transistor pair and ground. A differential voltage is applied across the first input of the first resistor and an inverting input of the amplifier (22). The darlington transistor pair converts an output voltage of the amplifier (22) to a feedback current for generating a voltage across the first resistor. Under stable conditions the voltage across the first resistor is equal to the differential voltage. The voltage gain is the ratio of the second resistor to the first resistor. The high side current sense amplifier (21) has excellent common mode voltage rejection and minimizes common mode error due to semiconductor wafer process variations.

Abstract: An assembly for controlling the position of a lens in an optical data storage and retrieval drive includes a carriage that suspends a lens holder using a plurality of flexures. A lens is mounted in the lens holder such that the center of mass of the suspended lens holder lies on the optical axis of the lens, and also coincides with the center of mass of the lens. The lens holder is capable of relative motion with respect to the carriage with at least one degree of freedom. The center of mass of the carriage lies within 0.1 mm of the optical axis, proximate the center of mass of the lens holder. Suspensory forces acting on the lens holder are symmetric about the optical axis. A coarse magnetic drive moves the carriage in a tracking direction, and exerts forces on the carriage that are balanced and symmetric about the optical axis, so that moments about the center of mass of the carriage are effectively absent. Inertial forces acting on the carriage, and forces reactive to the magnetic drive forces are also balanced and symmetric with respect to the optical axis, and produce insubstantial moments about the center of mass of the carriage. There is a fine tracking and a focusing drive for the lens holder. Both of these drives produce balanced and symmetric forces about the optical axis, such that moments about the optical axis are absent. Inertial forces and reactive forces acting on the suspended lens holder are also symmetric about the optical axis. As a result the objective lens moves along its optical axis, and in its tracking direction without change in attitude, and its focal point can be precisely controlled with respect to the surface of a storage medium being read or written.

Abstract: An acoustic correction apparatus 20 processes a pair of left and right input signals to compensate for spatial distortion as a function of frequency when said input signals are reproduced through speakers in a sound system. The sound-energy of the left and right input signals 26 and 28 is separated and corrected in a first low-frequency range and a second high-frequency range. The resultant signals are recombined to create image-corrected audio signals 27 and 29 having a desired sound-pressure response when reproduced by the speakers in the sound system. The desired sound-pressure response creates an apparent sound image location with respect to a listener. The image-corrected signals 27 and 29 may then be spatially-enhanced to broaden the apparent sound image.
