摘要： Apparatus for sensing linear displacement of an object between first and second locations along an axis is used to sense conditions that can be made to vary displacement of an object in accordance with the condition, such as temperature, pressure and rotary motion. A light beam projected along an incident light path to the object is reflected along a reflective light path by a reflector affixed to the object. A photo-sensor array in the reflective light path intercepts the reflected light beam and produces samples of the intensity of the reflected image at multiple positions along a line across the array. An imager coupled to the array converts the light samples to representative electrical samples. The resultant light intensity information is provided to an electronic processor which determines a first centroid of the reflected image when the object is at a first location and a second centroid when the object is at a second location, and employs the difference between the first and second centroids to determine the displacement of the object.

摘要： The signal processing apparatus includes a plurality of multiplying or charge splitting stages connected in series. A plurality of pairs of control words are provided, one word of each pair being the complement of the other word of the pair. Each pair of words is associated with a respective multiplying stage and represents the multiplying coefficient of a respective multiplying stage. Means are provided for forming a plurality of quantities of charge, each representing a respective sample of an analog signal. Each of the quantities of charge is introduced in sequence into each of the multiplying stages in which it is processed and then passed on to the next multiplying stage. The process operation in each of the multiplying stages includes dividing the quantity of charge in a series of splitting operations under the control of the pair of words associated with the stage into two parts. All of the first parts of each of the quantities of charge in each of the stages is summed. All of the second part of each of the quantities of charge in each of the stages is summed. A signal is derived representing the difference of the two sums of charge. The two parts of each quantity of charge are combined and passed to the next multiplying stage.

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 filter utilizing charge transfer devices for providing recursive transfer functions with a transmission zero at d.c. or zero frequency is described. The filter includes a circular charge transfer shift register having an even number N of stages, greater than two, and first, second, third and fourth linear charge transfer shift registers. All five shift registers are clocked at the same frequency. A first input sequence of packets of charge representing positive weight components of a signal, and a second sequence of packets of charge representing negative weight components of the signal are provided. Means are provided for dividing each of the packets of charge of the first input sequence into a first part and a second part and for applying each of the first parts of the packets of the first input sequence to the input stage of the first shift register and for applying each of the second parts of the packets of the first input sequence to the input stage of the second shift register. The charge packet in the first charge storage cell in the K.sup.th stage of the first shift register is combined with the charge packet in the first charge storage cell of the N.sup.th stage of the circular shift register. The combined packet of charge is divided into two portions, a first portion being stored in the first charge storage cell of the K.sup.th stage of the first shift register from which it is clocked out and sensed and a second portion being stored in the first charge storage cell of the N.sup.th stage of the circular shift register. The charge packet in the first charge storage cell of the L.sup.th stage of the second shift register is combined with the charge packet in the M.sup.th stage of the circular shift register, where M is an integer less than N/2 and L=K+M.Means are provided for dividing each of the packets of charge of the second input sequence into a first part and a second part and for applying each of the first parts of the packets of the second input sequence to the input stage of the third shift register and for applying each of the second parts of the packets of the second input sequence to the input stage of the fourth shift register. The charge packet in the first charge storage cell in the K.sup.th stage of the third shift register is combined with the charge packet in the first charge storage cell of the (N/2).sup.th stage of the circular shift register. The combined packet of charge is divided into two portions, a first portion being stored in the first charge storage cell of the K.sup.th stage of the third shift register from which it is clocked out and sensed and a second portion being stored in the first charge storage cell of the (N/2).sup.th stage of the circular shift register. The charge packet in the first charge storage cell of the L.sup.th stage of the fourth shift register is combined with the charge packet in the (N/2+M).sup.th stage of the circular shift register.A first output sequence of packets of charge representing the positive components of an output signal is obtained at the output of the first shift register. A second output sequence of packets of charge representing the negative components of the output signal is obtained at the output of the second shift register. The output signal is obtained by differentially summing corresponding charge packets in the first and second output sequences.

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.

摘要： A charge-coupled device (CCD) multiplying digital-to-analog converter mullies a bipolar analog signal, representing as a charge, by a digital word, and produces a four-quadrant analog product, also represented as a charge. An analog signal S is added to or subtracted from a bias, resulting in signals S+B and -S+B, which are converted into corresponding positive charges, Q.sub.S +Q.sub.B and -Q.sub.S +Q.sub.B, which are transferred into potential wells at X.sub.i and Y.sub.i, respectively. A digital word may be represented as b.sub.1 b.sub.2 b.sub.3 . . .b.sub.N, where N is the word length. The CCD converter comprises N parallel devices, each of which performs the function of multiplying the signal S by either 0 or 1/2.sup.i. A gate between X.sub.i and Y.sub.i is controlled by the binary bit b.sub.i. Equilibration occurs or does not occur depending on whether b.sub.i equals 0= or 1. The charges left in X.sub.i and Y.sub.i are then transferred to two other potential wells, which have channel stops diffused into them. The charges in the outer portions in each well are dumped to ground, while the remaining charges in each of the N devices are summed in a common potential well, to form a product as a sum of terms.
