Abstract: VIBRATION ATTENUATOR SEAT               Abstract of the Disclosure A vibration attenuator seat includes a seat assembly with a pair of paralleled shafts slidable in horizontally positioned, ultra low friction, linear bearings mounted in a base assembly.          A seat adjustment assembly has a bottom part which is a part of the base assembly and a latch in its top part for engaging the bottom part to lock the top and bottom parts in a plurality of positions.  A pin secured to the top part of the assembly centers the seat assembly relative to the top part by being connected by one preloaded, closed-coil spring to one end of the seat assembly and by a second preloaded, closed-coil spring to the other end.          The body of a shock absorber positioned parallel to the shafts is secured to the pin and the rod is secured to the seat assembly.        The latch allows positioning adjustment of the seat assembly relative to the base assembly and the shock absorber attenuates shocks and vibrations between the base and seat assemblies while the springs provide preloaded biasing towards the adjusted posi-tion.

Abstract: ANALOG-TO-DIGITAL AND DIGITAL-TO-ANALOG     CONVERTER CIRCUITS EMPLOYING CHARGE REDISTRIBUTION     ABSTRACT OF THE DISCLOSURE     Analog-to-digital (A/D) and digital-to-analog (D/A) converter circuits are provided using charge redistribution.  The analog-to-digital converter circuit also employs successive approximation binary search techniques wherein the number of search voltages generated is a minimum.          The analog-to-digital circuit includes a digital-to-analog converter circuit, a comparator circuit and a logic control means.  The digital-to-analog circuit, under control of the logic means, accepts a reference voltage input and produces a sequence of search voltages which are compared with an unknown analog input voltage at the comparator.  The resultant outputs from the comparator are applied to the control logic to determine the search voltage sequence.  The digital-to-analog converter for the aforesaid circuit is provided in one embodiment employing charge-coupled-device technology.  A substrate and two storage electrodes are combined to produce two potential storage wells and a transfer electrode is provided to move charge carriers between the storage wells.  A reference charge packet QR is stored and divided by charge redistribution between the two potential wells to produce a sequence of charge packets of value QR/2, QR/4, QR/8, QR/16 etc. which can be selectively combined to produce analog output of a D/A converter.          In the A/D converter the same sequence of charge packets is used to generate the equivalent of a binary search sequence QR/2, QR?QR/4, ?QR/8 etc.  In another embodiment a bucket brigade device is provided to accomplish the same result.  Because of the technique of charge redistribution wherein precise amounts of charge can be shifted in either direction between storage means, the total number of search value steps is a minimum.

Abstract: ABSTRACT OF THE DISCLOSURE           Electronic damping of a deflectable videotape transducer is effected by apparatus including a deflectable support arm for supporting the transducer and deflecting it in response to an electrical deflection signal.  A signal transducer generates a deflection velocity signal representa-tive of instantaneous deflection velocity of the transducer.          A feedback loop receives the deflected velocity signal, converts it to a damping signal, and applies the damping signal to the deflectable support arm to dampen vibrations therein.

Abstract: TIME-DIVISION SWITCHING SYSTEM     Abstract of the Disclosure A high-capacity low-blocking time-division switching system including a space-division switching network is disclosed for switching serial digital data words synchronously received on time multiplexed lines in a first code format wherein each data word occupies substantially an entire time multiplexed channel time period.  In order to achieve high capacity and low blocking, the space-division switching network is physically large resulting in delays of the digital data words transmitted therethrough, which delays are signifi-cant when compared with the time duration of a time-division multiplex channel and which vary in accordance with the path selected.  The communication paths through the stages of the space-division network are reconfigured each time-division multiplex channel time duration, but due to the transmission delays, the effective transmission period is less than the time duration of a channel.          Accordingly, data words are converted to a second code format, in which a start code is associated with each data word, and transmitted to the space-division network in a period of time less than the duration of a time multiplexed channel.  The start code is utilized to permit asynchronous reception at the network outputs which is necessitated by the variability of time delays through the network.   Additionally, the outputs of the space-division network are reconverted to the first code format for synchronous transmission on an output time-division multiplexed line.
