Abstract: Image data (U,V) are received from an image source and encoded (CCO′) at a low resolution in both line scan (horizontal) and field scan (vertical) directions, to obtain an array (CAR′) comprising n v  compressed series, each series containing n h  non-standard delta codes (dU,dV). The compressed series (CAR′) are then received in a display apparatus  via  a data channel (120′). Each non-standard delta code (dU,dV) is expanded into H identical standard delta codes (dU′,dV′) to generate n v  longer series of a first expanded type (112′) of delta codes, while the number n v  of series is increased by a factor V by generating intervening series of a second expanded type (174,176) in which groups of H delta codes comprise a mixture of the delta codes from corresponding groups in two successive series of the first expanded type. The expansion provides linear interpolation in the horizontal and (approximately) in the vertical direction, yet it can be performed within a standard low-cost display apparatus such as the Compact Disc - Interactive (CD-I) player.

Abstract: 2.1 In cordless telephones, it is known for each pair of radio stations to agree with one another m radio channels of n possible radio channels. During a test cycle, the mobile part investigates only the agreed radio channels. In consequence, the test time which is required to check only the agreed channels is shorter than the time which is required to check all the channels. If, by chance, all the agreed channels are busy, or such a situation is created by an incorrect function, it is no longer possible to maintain a connection between the base device and the mobile part. 2.2 In the proposed design of a cordless telephone, reliable setting up of a call is ensured in that the agreed m radio channels are tested in a first test phase and all n radio channels are tested in a second test phase. 2.3 One field of application of the invention is in the area of cordless telephones. <IMAGE>

Title: Method and apparatus for automatic write current calibration in a streaming tape drive
Inventor: SHEEHAN MICHAEL SCOTT
IPC: G11B5/008
Filed: 1990-02-28
Abstract: An apparatus and a method for calibrating the write current applied to a write head (110, 114) in a tape drive (100) finds the peak value of the write current applied to the tape head (110, 114) (i.e., the write current value providing the maximum read voltage amplitude on a tape (104)) by indirectly measuring the voltage sensed by a read head (112, 115). The apparatus includes a digital write current control circuit (170, 160) that applies a write current having a magnitude responsive to a digital write current value. An amplifier (190) in a read circuit (180, 182, 184, 190, 196) has a gain responsive to a digital read gain value. The method includes the steps of sampling the output of a pattern detector (146) (e.g., a gap detector) as the digital read gain value is adjusted for each of a number of digital write current data values applied to the write current control circuit (170, 160). The digital read gain value is adjusted to provide a predetermined range of the number of samples wherein the pattern corresponds to a predetermined pattern. The digital read gain value for each digital write current value is inversely related to the amplitude of the signal recorded on the tape (104). The sampled digital read voltage gain values are then stored. The digital write current value corresponding to the minimum stored digital read gain value also corresponds to the peak value of the actual write current. The digital write current value corresponding to the minimum digital read voltage gain value is then selected and stored as the calibrated digital write current.

Abstract: A hydraulically-actuated starting clutch (10) for a continuously variable transmission which is designed to reduce the centrifugal torque of the clutch with respect to the chain belt/sheave torque. This is accomplished by adjusting the diameters of the clutch piston (18) to reduce the resultant clutch torque to a value lower than the chain belt/sheave torque. A pair of oil feed passages (83, 84) are positioned in the clutch assembly to feed oil through openings (82) in the friction plate (78) at all times during operation, even when rotation of the friction plate ceases. Further, an improved retractor spring (64) is utilized in the clutch assembly (10) with circumferentially extending tabs (68) on its inner periphery (66) which extend over the snap ring (62) holding the spring onto the actuating piston (18) to prevent release of the snap ring due to centrifugal force during operation of the clutch.

Abstract: A data storage device includes optical media or magneto-optic media. Formed on the optical or magneto-optic media is an amorphous or a substantially amorphous ZrO₂ layer (102; 204). The ZrO₂ layer is typically formed by sputtering, and includes an additive which renders the ZrO₂ either amorphous or substantially amorphous. Because of the amorphous or near amorphous nature of the ZrO₂ film (102, 204), noise is not introduced into a laser beam signal passing therethrough by crystal grain boundaries in the film (102, 204). In addition, because the film (102, 204) is substantially amorphous, birefringence will not generate noise in the laser passing therethrough caused by polymorphism in the film (102, 204).

Abstract: A video data processing apparatus converts one of NTSC type and VGA type video signals to the other or overlays the two types of video signals and outputs them as either an NTSC type overlaid video signal or a VGA type overlaid video sigal. The processing apparatus has two video memories (156, 174) for storing video signal data. One of the two video memories stores solely VGA type video data. The other video memory stores either VGA type video data or NTSC type video data depending upon the particular function being carried out by the processing apparatus. Video data may be read out from the other video memory using different scan rates so that an individually dedicated memory is not required for each type of video data in performing the above-mentioned conversions and overlays.

Abstract: The present invention is related to speech recognition and particularly to a new type of vector quantizer and a new vector quantization technique in which the error rate of associating a sound with an incoming speech signal is drastically reduced. To achieve this end, the present invention technique groups the feature vectors in a space into different prototypes at least two of which represent a class of sound. Each of the prototypes may in turn have a number of subclasses or partitions. Each of the prototypes and their subclasses may be assigned respective identifying values. To identify an incoming speech feature vector, at least one of the feature values of the incoming feature vector is compared with the different values of the respective prototypes, or the subclasses of the prototypes. The class of sound whose group of prototypes, or at least one of the prototypes, whose combined value most closely matches the value of the feature value of the feature vector is deemed to be the class corresponding to the feature vector. The feature vector is then labeled with the identifier associated with that class.

Abstract: The microcomputer architecture and method provide for automatic conveyance of system memory configuration information to a memory controller (112) which controls a system memory (110) having numerous allowable memory configurations. The system memory (110) is comprised of conventional SIMMs (1-N) which carry varying DRAM capacities. Each SIMM (1-N) bears a number of unused external pins, which can be used to decipher the DRAM configuration pertaining to that particular SIMM. The SIMMs (1-N) are arranged in pairs and only the unused pins of one SIMM per pair are monitored. During the initialization of the system memory (110), data signals from all of the recognized pins are transmitted to a programmable logic array (PAL) (116), which translates the data signals into a control signal encoding the entire system memory configuration. The control signal is transmitted to the memory controller (112), which recognizes the signals through internal software (227). The internal software (227) performs a two-step analysis to determine the system memory configuration and to insure that the configuration conforms to one of numerous preselected allowable configurations.

Abstract: An IC (Integrated Circuit) memory card system having a host processor (100) and an IC memory card capable of storing picture data or similar data. When the host processor (100) rewrites data stored in the memory card, the processor sends (100) an erase signal together with state signals to the memory card with no regard to the type of a memory built in the latter, i.e., an SRAM (Static Random Access Memory) or an EEPROM (Electrically Erasable Programmable Read Only Memory). The memory card (200) with an EEPROM erases data in response to the erase signal, while the memory card with an SRAM awaits data from the host processor by neglecting the erase signal. During the erasure, the memory card (200) with an EEPROM continuously sends a busy signal to the host processor (100) to cause it to temporarily stop sending data. On completing the erasure, the memory card (200) cancels the busy signal, receives data from the host processor (100), and writes them in. In the case of the memory card with an SRAM which does not send the busy signal, the host processor (100) continuously sends data thereto without interruption.
