Abstract: SAMPLE AND HOLD CIRCUIT Abstract of the Disclosure A sample and hold (S/H) circuit that produces an output signal having essentially zero offset voltage error is disclosed. The S/H circuit includes a pair of operational amplifiers (OA3 and OA4) that are connected in circuit during both the sample and the hold modes of operation. In the sample mode of operation one of the operational amplifiers (OA3) receives the incoming signal through a first resistor (R1) and in accordance therewith controls the magnitudeof an inverted voltage stored on a storage capacitor (C1); and, the other operational amplifier (OA4) senses the stored inverted voltage and, in accordance therewith, applies a feedback voltage to the signal input of OA3 through a second resistor (R2). In the hold mode of operation OA4 senses the voltage stored on C1and, in accordance therewith, via R2 and OA3 controls the output voltage, which has the correct polarity due to the inverted voltage being inverted by OA3. In addition, during the hold mode of operation, the output voltage is fed back through R1 to the input of OA3 receiving the output of OA4. If the resistance ofR1 equals the resistance of R2, the magnitude of the voltage stored by C1 is equal to the input signal voltage. If the resistance ratio of R2 to R1 is greater than one, the magnitude of the stored voltage is greater than the input signal voltage, even though the output voltage is equal to the input signal voltage. Storing a higher level voltage reduces the effect of capacitor leakage and OA4 drawing current from C1 on the output voltage.

Abstract: SPECIFICATIONS OF Edwin M. Petryk Jr.   A RECEIVER APPARATUS FOR CONVERTING OPTICALLY ENCODED         BINARY DATA TO ELECTRICAL SIGNALS                      ABSTRACT OF THE DISCLOSURE There is disclosed herein an apparatus for receiving optically encoded binary data transmitted over an optical fiber from an optical transmitter device coupled to another data processing system. The receiver apparatus is used to convert the light signal carrying the subject data into TTL level digital logic signals. The receiver apparatus is comprised of circuity for converting the optically encoded data into electrical signals in serial format, and circuitry for converting these electrical signals into TTL level digital signals in parallel format for use by a user device. The primary advantage of the apparatus disclosed herein is the ability to substitute a single optical fiber for a plurality of parallel copper wires for carrying data between one data processing device and another with little or no loss in speed due to the larger band-width of optical fibers. Another significant advantage is the ability to couple data processing systems directly over much larger distances than possible with average cost parallel copper wire electrical cables. Higher noise immunity and communications security is also enjoyed. In the preferred embodiment, the receiver apparatus comprises a photodiode for converting the light signal into an electrical signal followed by an amplifier for changing the electrical signal to TTL digital logic levels. A clock generator and header detector recover a clock signal and detect the receipt of a header signal indicating transmission of a serial format data packet has commenced. A serial in and parallel out shift register/data latch storage buffer combination utilizes a signal derived from the recovered clock signal to shift the incoming data bits into the shift register and latch them into the data latch output buffers in parallel format when a counter signals that an entire data packet has been received.

Abstract: Abstract of the Disclosure The present invention relates to a method for the manufacture of a high-tensile-strength light waveguide with a plastic layer on the optical fiber, in which a hardenable polymer precursor stage is applied to the optical fiber.  Uniform, thick layers are produced in a single operation in a process comprising applying an oligomeric and/or polymeric polyaddition or polyconden-sation product to the optical fiber from a solution and subsequently irradiat-ing with actinic light and/or performing a thermal treatment.  The polyaddition or polycondensation product is made from a carbocyclic or heterocyclic compound which carries two functional groups suitable for addition or condensation re-actions, and a diamine, a diisocyanate, a bis-acid chloride or a dicarboxylic acid.  The carbocyclic or heterocyclic compound has in a position adjacent to the functional groups partially ester, amide, urethane or urea groupings which may be of an unsaturated nature.  The light waveguides made by the method according to the invention are suitable particularly for purposes of optical information transmission.

Abstract: CONTROL CIRCUITRY USING A PULL-DOWN TRANSISTOR FOR HIGH VOLTAGE SOLID-STATE SWITCHES            Abstract of the Disclosure To switch a first gated diode switch (GDS) to the "OFF" state requires a voltage applied to the gate which is more positive than that of the anode or cathode and the sourcing of current into the gate which is of the same order of magnitude as flows between the anode and cathode.  Control circuitry, which uses a second GDS coupled by the cathode to the gate of the first GDS, is used to control the state of the first GDS.  The state of the second GDS is controlled by a branch circuit having a relatively modest current handling capability.  An n-p-n junction transistor has the emitter and collector coupled to the cathode and gate, respectively, of the first GDS, and has the base coupled through a p-n-p transistor to the input terminal of the control circuitry.  The n-p-n transistor facilitates a quick turn-on of the first GDS by rapidly bringing the potentials of the gate and cathode of the first GDS to levels which are close together.

Abstract: METHOD AND APPARATUS FOR P _V NTING ERRORS IN PCM SIGNAL                 PR~CESSING APPARATUS     ABSTRACT OF THE DISCLOSURE         A technique is disclosed-for preventing errors in a PCM error-correction decoder of the type supplied with successive transmission blocks, each comprised of time-interleaved PCM,error-correction and error detection words, wherein the transmission blocks are selectively supplied from first and second data sources such that an error interval is produced as a function of the transition period during which the selection of the data sources is changed over from one to the other.  According to this technique, the presence of an error in a supplied transmission block is detected, and each of the time-interleaved words included in that transmission block is identified as being erroneous.  The transmission block is time de-interleaved to recover a de-interleavec block comprised of de-interleaved PCM and error-correcti words.  An erroneous PCM word in the de-interleaved block is corrected as a function of the remaining  non-erroneous PCM and error-correction words in that de-interleaved block.  However, the correction of a PCM word is inhibited if the block in which that word is disposed contains at least one word derived from the first data source and another word derived from the second data source.
