Inventor: SEDGWICK NIGEL CHARLES
IPC: G10L21/0208
Filed: 1987-04-01
Abstract: In speech recognition it is advantageous to take account of noise levels both in recognition and training. In both processes signals reaching a microphone 10 are digitised and passed through a filter bank 13 to be separated into frequency channels. In training a noise estimator 18 and a masker 15 are used with a processor 17 to prepare template signals which are held in a store 16. In each region the template signals are made equal to the highest noise level in that region during the whole training process if below this level. In recognition the input signals in each region are made equal to the highest noise level in that region if below this level. "Distance" measurements for each region on which recognition is based depend on the levels of the template and input signals unless either is represented by noise when the relative levels determine how the distance shall be calculated.

Abstract: Apparatus for multiplying a sampled data signal by a sinusoid having a period which is a multiple of the sample rate includes a plurality of sample scaling means (116) to scale the sampled data signal by factors corresponding to the sine of angle ϑ over an angular range of 90 degrees in angular increments of 2π divided by said multiple. A multiplexer (118,120) multiplexes the scaled samples at the sample rate to produce a signal corresponding to the sampled data signal multiplied by the sinusoid. The data sample rate is phase-locked to the sinusoid. An embodiment is described for demodulating the stereo difference signal of a BTSC sound signal with serial-bit digital processing circuitry.

Abstract: In a deflection circuit such as for a CRT display device, modulated current that is generated in a raster control circuit especially for East-West pincushion distortion correction, is coupled to a deflection circuit output stage (100) via a Class A operated amplifier (Q2) serving as a current source having a high output impedance during retrace. The current source prevents coupling of a signal at a retrace frequency during retrace between a high voltage winding (W1) of the flyback transformer (T1) and a retrace resonant circuit (27) that includes the deflection winding (L H ). The high output impedance of the amplifier current source during retrace maintains the average value of the modulated current during retrace unaffected by an amplitude of a retrace voltage that is developed in the retrace resonant circuit (27). In this way, ultor voltage loading variation is prevented from causing "mouseteeth" distortions.

Abstract: A method of making a windshield is disclosed. A first glass template (10) is cut. An opaque material (12) is bonded to a surface of the glass template. A conductive material is bonded to portions of the opaque and portions of the surface of the glass template to form electrically conductive terminals (14,16). A slippage inducing material (22) is placed on portions of the opaque area not having electrically conductive terminal material thereon. A second glass template (24) is cut. The first and second glass templates are placed in a glass bending device (26). The glass templates (10,24) are bent with the electrically conductive terminal areas and slippage inducing material permitting relative movement between the templates during the bending thereof without the production of glass chips. The first and second glass templates (10,24) are separated and an electrically conductive coating is applied between terminal areas of opposite polarity on the first glass template (10). The glass templates (10,24) are reunited with an interposed laminating interlayer and laminated to form a laminated glass windshield.

Abstract: A method for aligning and bonding the outer leads (20) of the conductive fingers (16, Fig.3) of a tape-and-semiconductor-chip sub-assembly to a package substrate (12) is disclosed. Each section of tape is provided with an inner support ring (18) and an outer support ring (22). The conductive fingers extend from under the inner support ring (18) to under the outer support ring (22). The outer support ring (22) is spaced away from the inner support ring (18) to expose portions (23) of the tape outer leads (20) therebetween. The tape-and-chip sub-assembly (10) is positioned over the package substrate (12) so the outer leads (20) are in register with the appropriate package substrate leads (26). A deposit of flux (28) is applied to at least one location (30) between the substrate (18) and outer support ring (22) to bond the sub-assembly to the substrate. The bonded outer support ring prevents the sub-assembly from moving so the leads do not become out of register with the substrate prior to and during the lead bonding process.

Abstract: An electro-optical sensor (10) for measuring distance to a test surface, such as a road surface beneath a vehicle frame on which the sensor is mounted. The sensor includes a modulated light source (12) for directing a light beam onto the test surface, and a photosensitive detector (22) for receiving light diffusely deflected from the test surface and providing a pair of output signals (A, B) indicative of orthogonal position coordinates of reflected light incident on the detector. The detector outputs (A, B) are fed to amplifiers (46, 50) for obtaining sum (A+B) and difference (A-B) signals which are demodulated synchronously with energization frequency of the light source. Distance to the test surface is determined as a function of a ratio (P) of the detector output differential (A-B) to the detector output sum (A+B). In the preferred application of the invention for road profile measurement, a signal indicative of road profile is stored at increments of vehicle motion along the road surface.

Abstract: An atomic ordered sequence of information phase transitions allows for the design of a pure hardware protocol controller for use in a small storage interconnect bus. The information phase transitions follow the sequence: Command Out phase, Data Out phase, and Status In phase. The only other transition sequence allowed is from the Command Out phase directly to the Status In phase. The Command Out phase is actually a header delivering header information. Included in the header are a REQ/ACK offset byte, source destination ID verify byte, frame length bytes, and a checksum byte. The Data Out phase contains any number of bytes that were defined in the Command Out frame length byte. The Status In phase is a single byte which is used to signal the outcome of the attempted data delivery.
