Abstract: Abstract of the Disclosure:     An echo cancelling circuit is composed of digital circuits, An echo canceller is supplied with lower send-in and receive-in components derived from a send-in and a receive-in digital signal, respectively, in a lower frequency band below a predetermined frequency,  The echo canceller produces a lower digital signal component which is free from a lower echo signal component, The echo canceller furthermore produces a control signal indicative of presence and absence of a lower voice signal component in the lower send-in component,  Controlled by the control signal and supplied with a higher send-in component of a frequency band higher than the predetermined frequency, an adjustable attenuator produces a higher digital signal component in which a higher echo signal component is suppressed with no attenuation and either a constant or a variable positive attenuation given to the higher send-in component when the control signal indicates presence and absence of the lower voice signal component, respectively, The lower and the higher digital signal components are combined into a send-out signal exempted from the echo signal, which may or may not comprise a reverberation signal introduced into the send-in digital signal by audible sound reproduced from a voice signal carried by the receive-in digital signal.

Abstract: ABSTRACT     An apparatus for fluid handling and delivery in a medication infusion system is disclosed.  The apparatus generally contains a pulsatile pump in combination  with at least an accumulation flow restrictor.  The pulsatile pump is economical in electrical consumption by virtue of the use of a spring force pumping action.  The accumulator flow restrictor smooths the output from the pulsatile pump so that medication is delivered in a manner compatible with human or animal body needs.  As an example, for infusion of medication such as insulin, the medication infusion system can provide an infusion flow profile which mimics that of insulin production in a normal person.

Abstract: ABSTRACT OF THE DISCLOSURE           Sudden accidental or unintended movement of an automatic transmission into reverse with the engine running is prevented by substituting for the usual unitary control rod a two part arrangement, one being movable by the shift lever and the other being movable by a spring separator from the shift lever but arranged to exert a force only in the direction of a parking pawl and never in the reverse direction against any member connected to the detent plate.          Thus it is impossible for a yieldlng cam spring to ever drive the linkage unexpectedly into reverse should a driver carelessly position a shaft lever between its reverse and park positions.

Abstract: ELECTRONIC SOUND DETECTING UNIT FOR LOCATING MISSING ARTICLES            Inventor:  Edward B. Bayer ABSTRACT OF THE DISCLOSURE   A miniature,   battery-powered   electronic   unit adapted to be attached to a common article such as keys or eyeglasses.  The unit is responsive to a plurality of  sounds  for  emitting  audible  tones  to  enable  a misplaced article to be located.  A sound detecting and indicating  circuit provides  the  audible  tones  upon receipt  of  a  sequence  of  sounds  falling  within predetermined  frequency,  time  spacing  and  amplitude ranges.  The correct sequence of sounds is generated by the user by clapping,  whistling or making any other loud sounds, and no additional transmitting device is required.   Improper sequences of sounds are prevented from producing false activation of the unit.  Extremely low power  consumption,  resulting  in  part  from  CMOS technology, allows the unit to remain on continuously for  a  period  of  six  to  nine months  using  standard camera (button cell) batteries.   Special battery-saver circuitry  prolongs  battery  life.    The  unit  can  be fabricated using gate array or custom chip technology, which results in extremely small size and low cost of manufacture.  A visual indicator (270) allows the user to learn proper operation.

Abstract: Abstract of the Disclosure A swept interference canceller including a multiplexed interference cancelling receiver coupled to a scanned notch antenna and an omni-directional antenna as well as an estimator type of angular beam splitting system for accurately measuring angular bearing or a plurality of sequentially received radiating sources in a dense communication environment.  A difference signal between the signals received by the two antennas is developed which is then split into a plurality of equal time samples which are then simultaneously fed into two synchronous multi-stage shift registers.  The output stages of one of the shift registers operate so that they all have the same output states.  The output stages of the other shift register, however, operate so that the first half have the same output state as the first shift register while the second half are of the opposite output state.  The outputs from the two shift registers are summed and fed to a logic gate which operates to generate an output signal following the occurrence of the middle time sample which is a time corres-ponding to the position of the boresight axis of the signal received from a radiating source.

Abstract: Abstract of the Disclosure A robotic manipulator has three linearly extensible arms mounted on a frame in a triangular array and carrying at their remote ends a connector interface coupling the arms to a tool for manipulating parts to be positioned or for other work.  The structure is such that the location of the connector is determined solely by the lengths of the arms, while its orientation is determined primarily by controllably rotating the connector with respect to the arms.  The decoupling of position and orientation minimizes the computation required to accurately position a tool.  In the preferred illustrative embodiment, the rotation is performed by driving motors for the arms which are located at the arm ends adjacent the frame; this minimizes the mass, and thus the inertia, that is located at the connector end, and enables high acceleration and rapid motion of the connector head and its associated tool.  Further, a three-point suspension for the arms provides high stiffness, thereby enabling the system to carry substantial loads at high speed and with good positioning and orientation accuracy.

Abstract: ABSTRACT OF THE DISCLOSURE          Increased forward and rearward flex of a skate boot about the ankle joint is provided while maintaining sufficient lateral support.  This flex is provided by preferrably removing a portion of the skate in the achilles tendon region above the heel.  The flex characteristics can further be improved by providing notched areas at the front of the skate to avoid buldging when the skate is flexed forwardly.  A reinforcing member is applied to the cut-out region to provide supplementary lateral support but is constructed to accommodate forward and rearward flexing.  A skate of this design significantly reduces damage to the soft tissues adjacent the achilles tendon caused by restricted pivoting movement of the leg about the ankle.
