Abstract: PHN. 10.658               10 ABSTRACT:           Transmission circuit for a telephone set for DTMF-tone selection.  The required second-order tone filter is formed by arranging the speech filter (12) during the dialling procedure in series with a fixed first-order tone filter (10) by means of a switch (11). The resultant attenuation of the group II of high fre-quencies of the dialling tones is compensated for by increasing the amplitude of the dialling tones of the high-frequency group II and  by an additional increase in the sub-group II(2) of the two highest frequencies of this group.

Abstract: ABSTRACT      In a bolt assembly for inertial operating automatic fire-arms using the kinetic recoil energy, of the type comprising a locking bolt head and a floating bolt element with a spring interposed between them, the locking bolt head is a rotatable head having a cylindrical portion (1) and a shank (2) narrowed with respect to the cylindrical portion.  The cylindrical portion (1) has two radial crescent shaped diametrically opposite pro-jections (6),  (7) adapted to engage each an associated groove (12),  (13) provided in the barrel (9) and to disengage therefrom by passing through two associated recesses (10),  (11) having a shape corresponding to that of the two crescent shaped projections (6),  (7) of the head. The shank (2) of the locking bolt head is received in a cylindrical bore (21) of the floating bolt element (19) and engages by means of a pin (5) projecting therefrom a helical slot (20) of the floating bolt element (19).  Interposed between the shank (2) of the rotatable locking bolt head and the floating bolt element (19) is a spring (30).  When the arm is locked the projections (6),  (7) of the cylindrical portion (l) of the locking bolt head are in the associated grooves (12),  (13) of the barrel (9).  At firing, at the beginning the floating bolt element (19), because of its reaction to the recoil of the arm, advances and compresses the spring.  Immediately after the spring (30) spreads out and causes the floating bolt element (19) to move back which unlocks the rotatable locking bolt head and causes the pin (5) to slide in the helical slot (20) thus disengaging the rotatable locking bolt head from the barrel (9) and causing the projections (6), (7) of the cylindrical portion (l) of the head to pass through the two recesses (10),  (11) of the barrel (9).          The arm is thus open and reloads itself automatically in a conventional manner.

Abstract: ABSTRACT          In a transmission system for transmitting voice signals each signal being sampled and coded to derive therefrom blocks of samples and  short term power  spectrum characteristics or each block, a voice activity detection process is proposed wherein an energy representative information is derived from each   block   of   sample,   which   energy   representative information is compared with a predetermined threshold and said   threshold   is   adjusted   accordingly.   Then   an active/ambiguous decision is taken based on the relative magnitude of  the energy information with respect to  the adjusted  threshold,  which  ambiguity  is  then  eventually resolved through analysis of the magnitude of variation of the short term power spectrum characteristics.

Abstract: ABSTRACT    Disk or Wafer Handling and Coating System A system for handling and individually processing a plurality of thin substrates is described.  The system includes a main chamber, entrance and exit load locks, a plurality of processing stations, a load lock load/unload means, a vertical transport means, and a horizontal transport means.  In one embodiment the processing stations are deployed in a U-shaped configuration, allowing the entrance and exit load locks to be positioned at the same end of the machine.  Idle stations between processing stations may also be employed.  The substrates are vertically oriented and are raised and lowered into and out of load locks and processing stations by means of dedicated lift blades.  Substrates are transferred within the main chamber from lift blades of one station to lift blades of an adjacent station by means of substrate carriers affixed to a walking beam mechanism.  Substrates are transferred from the entrance load lock side of the machine to the exit load lock side by means of a reversing mechanism, which may be a rotating beam mechanism, or which may be a transverse motion mechanism which affects a rotationless substrate transfer.  A lift blade symmetrically engages a substrate nearer the lower half of its periphery, holding the substrate securely with the aid of gravity, and negligibly obscuring or eclipsing either surface of the substrate.  The lift blades carry the substrates into the processing stations and hold them in place during processing, or simultaneous processing of both sides of the substrates may be carried out.     Such a procedure is highly desirable in vacuum coating of magnetic disks.  Sealing means associated with the lift blades serve to isolate all processing stations and load locks from the main chamber and from each other during processing, and dedicated vacuum pumping means may be employed for the main chamber, the load locks, and the processing stations.  Cross-contamination due to a variety of processes occurring simultaneously may therefore be greatly reduced.  Any number of the individual processing stations may be serviced without breaking vacuum of the main chamber or other processing stations, whereby system downtime due to such servicing may be greatly reduced.

Granted: 1987-12-01
Abstract: Abstract of the Disclosure A speech recognition method and apparatus employ a speech processing circuitry for repetitively deriving from a speech input, at a frame repetition rate, a plurality of acoustic parameters.  The acoustic parameters represent the speech input signal for a frame time. A plurality of template matching and cost processing circuitries are connected to a system bus, along with the speech processing circuitry, for determining, or identifying, the speech units in the input speech, by comparing the acoustic parameters with stored template patterns.  The apparatus can be expanded by adding more template matching and cost processing circuitry to the bus thereby increasing the speech recognition capacity of the apparatus.  The speech processing circuitry establishes overlapping time durations for generating the acoustic parameters and further employs a sinc-Kaiser smoothing function in combination with a folding technique for providing a discrete Fourier transform.  The Fourier spectra are transformed using a principal component analysis which optimizes the across class variance.  The template matching and cost processing circuitries provide distributed processing, on demand, of the acoustic parameters for generating through a dynamic programming technique the recognition decision.  Grammar graph structures reduce the computational load by allowing activation and deactivation of patterns of the graph depending upon the cumulative scores associated therewith.
