摘要： A high resolution analog-to-digital (A/D) converter (14) and a pipelined A/D converter are used in a single system so that unknown offset and gain errors of the pipe-lined A/D converter are determined and corrected. Each stage of the pipelined A/D converter includes a flash A/D converter (16), a corresponding digital-to-analog (D/A) converter (18), and a differential amplifier (20) so that, in each stage the output voltage of the D/A converter is subtracted from a sample of the analog input voltage, to constitute the input signal for the next stage. The flash A/D converter of each stage addresses digital words in memory (22) which, when summed by an adder chain (24), constitute the output signal of the system. The flash A/D converter output signals are also supplied to corresponding stages of a shift register (28 or 28') which accumulates the memory address bits. A comparator and finite state machine (26) receives the memory address bits from the shift register and iteratively compares the digital output signals of the pipelined A/D converter and the high resolution A/D converter and corrects the words in memory addressed by the flash A/D converters to improve resolution of the system.

摘要： Methods for storing and transferring electrical charges between adjacently spaced storage regions in semiconductor substrate are disclosed. In one embodiment, a plurality of adjacently spaced conductor members are insulatingly disposed over a major surface of a semiconductor substrate. Each storage region is separated from each other storage region by an electrical barrier region underlying the spacing between the adjacent conductor members. These barrier regions are controllably lowered by an electrode interposed between adjacent conductor members. Electrical charges stored in one storage region are transferred to an adjacent storage region by applying a voltage signal to the interposed electrode to lower the barrier region between the adjacent storage regions. Direction of charge transfer is controlled by the relative surface potentials of the adjacent storage regions and the magnitude of transfer is controlled by the height of the barrier region when lowered. Means for transferring partial charges are disclosed along with means for periodically regenerating charges to a predetermined level. Methods for transferring electrical charges with high efficiency of transfer are also disclosed.

摘要： A mobile tracking unit capable of operating in a power-starved environment for a vehicle tracking system includes a navigation set for generating data corresponding to a respective vehicle position. The navigation set is periodically energized at a selected activation rate F.sub.G while the vehicle is moving to generate the vehicle position data. The tracking unit includes an electromagnetic emitter which is capable of transmitting the vehicle position data and which is periodically energized at a selected activation rate F.sub.EM while the vehicle is moving to transmit at least the vehicle position data. A motion sensor is employed for generating data indicative of vehicle motion. A tracking unit controller receives the vehicle motion data and controls the navigation set and the emitter based upon the vehicle motion data so that when the vehicle is stationary each of activation rates F.sub.G and F.sub.EM can be respectively decreased by a predetermined factor, thus reducing the overall power consumption of the tracking unit. The tracking unit controller is further designed to return to activation rates F.sub.G and F.sub.EM upon the motion sensor sensing renewed vehicle motion, thus avoiding loss of vehicle position data during times of renewed vehicle motion.

摘要： A simple digital filter having only a single multiplier operates to extract the pilot tone from a demodulated and digitized FM stereo signal. The number of poles in the filter is chosen so that the filter output is also usable to produce a digitized representation of the carrier tone for the left minus right stereo channel. This signal is in turn used to decode the input representation into the desired left and right channel signals. The circuit of the present invention is particularly amenable to fabrication on an integrated circuit chip.

摘要： A system is described which makes use of the fact that in a raster scanned television system a high degree of correlation exists both in the luminance and in the chrominance signals of a pair of adjacent lines. Because of this correlation, the difference between the luminance signals of the two lines is usually much smaller than luminance signal of either line alone, and requires less bandwidth. The present invention takes advantage of the natural correlation in a television picture in the horizontal and vertical directions for bandwidth reduction without significant impairment of the reproduced picture. This is accomplished by processing the television signal for bandwidth reduction in particular ways and transmitting it entirely in the analog domain. The bandwidth requirement is reduced for the transmission of the video signals over a transmission channel such as a cable television channel, a broadcast channel or a storage medium.

摘要： A real time ultrasound imaging system which includes coherent demodulation of echo signals followed by time delay and coherent summation of the demodulated signals is described. As the range from which echoes are being received increases, coherent demodulation is maintained. Demodulation and time delay accuracies are relatively easy to maintain over a large field of view and a long range. The system has high resolution and high sensitivity.

摘要： A first video signal is provided comprising a plurality of lines of a luminance signal, a first color signal and a second color signal, each of the lines having a duration of a first predetermined time. Each of the nonoverlapping pairs of successive lines of the luminance signal are summed and differenced to provide a luminance sum signal and a luminance difference signal. Each of the nonoverlapping pairs of successive lines of the first color signal and also of the second color signal are summed to provide a first color sum signal and a second color sum signal. The luminance difference signal, the first color sum signal and the second color sum signal are bandwidth limited in relation to the luminance sum signal. Corresponding lines of these signals are time compressed to the same bandwidth and then time multiplexed to form a corresponding line of a first compound signal, each line of which has a duration of the aforementioned predetermined time, and alternate lines of which have zero amplitude. A second video signal is similarly processed to provide a second compound signal. The first and second compound signals are interleaved to form a third compound signal such that the time of the non-zero amplitude of the second compound signal occupies the time when the first compound signal has zero amplitude. A carrier is modulated in amplitude by the third compound signal for transmission to a receiving station. The bandwidth of the modulated carrier is comparable to the bandwidth of a carrier that is amplitude modulated by one of the video signals. The carrier is demodulated at the receiving station to recover the third compound signal. The first or second compound signal is recovered from the third compound signal. Inverse operations are utilized to recover the first or second video signals.

摘要： A sampled data transversal filter utilizing charge transfer devices is described. The filter includes a charge transfer shift register including a plurality of stages to which a sequence of packets of charge representing samples of a signal is serially applied and clocked from stage to stage. Charge division and collection means are provided at the various stages of the shift register to divide and collect the fractions of charge appearing in the various stages thereof. These fractions represent the weighting coefficients of the various stages of the shift register. The charge collection means of the various stages are connected together to provide an output representing the sum of the charges collected at the various stages. The output sequence of packets of charge obtained represent the convolution of the input sequence of packets with the weighting coefficients of the various stages of the shift register.

摘要： A conductor-insulator-semiconductor (CIS) structure for a random access surface charge memory system is disclosed. The memory system comprises an array of memory cells including charge storage regions, charge transfer regions and charge receive-source regions formed along the surface-adjacent portions of a semiconductor substrate. A charge-storage line insulatingly overlies the storage regions of a row of memory cells and a bit line, comprising an extended region of opposite-conductivity-type, interconnects the receive-source regions of the same memory cells. Addressing in the Y-direction (word selection) is provided by charge transfer lines insulatingly overlying the charge transfer regions of a column of memory cells. Selected memory cells are addressed for read and write purposes by first activating the word select line which makes available one cell in each row of the memory. The desired row is then selected by means external to the array of memory cells. All cells of the selected word line are refreshed, but only one cell is addressed for read and write purposes. Means for reading, writing and refreshing data in the memory system are also disclosed.
