Patent CA-1281822-C (CA)
Inventor: ITOH NORIO
IPC: H04B7/14
Filed: 1987-09-17
Granted: 1991-03-19
Abstract: Abstract of the Disclosure:         In a repeater station (20) for receiving a first downward signal from a next preceding station (21) with a propagation delay and for transmitting a second downward signal to a next succeeding station, a first delay circuit (15) gives a fixed delay to the first downward signal to produce a delayed signal for use as the second downward signal.  The first downward signal has a frame period and includes a reference signal and a number signal representative of an integer for the repeater station.  The fixed delay is rendered equal to an integral submultiple of the frame period minus the propagation delay.  A first detector (17) detects the reference signal to produce a first detection signal.  A second detector (23) detects the number signal to produce a second detection signal representative of the integer.  Responsive to the second detection signal, an internal delay circuit (24) gives an internal delay to the first detection signal to produce a delayed detection signal.  The internal delay is decided in consideration of the integer.  Responsive to the delayed detection signal, a multiplexer (25) processes a first upward signal received from the succeeding station into a processed signal.  A second delay circuit (26) gives the fixed delay to the processed signal to produce a second upward signal which should be received by the preceding station with the propagation delay.  The repeater station may be used as a terminal station.

Title: On-line paper sheet formation characterizing method and device
Inventor: CHASE LEE M
IPC: G01N21/86
Filed: 1987-10-27
Granted: 1994-06-21
Abstract: ABSTRACT OF THE DISCLOSURE A device for characterizing the formation of a sheet material is described.  The device comprises a basis weight sensor for measuring the basis weight of the sheet material as the material passes through the sensor and signal processing circuitry which receives a signal from the basis weight sensor indicative of the measured basis weight and which produces three types of outputs, which outputs characterize: (1) the magnitude of variation in the sheet basis weights (2) the strength of  the weakest portion or portions of the sheets and (3) the size of the flocs comprising the sheet.  The basis weight sensor includes a light pipe which is held against the sheet, as the sheet moves through the sensor, and which directs a small spot of light transmitted through the sheet to a light detecting device.  The magnitude of variation in the sheet basis weight is computed to be proportional to the true root-mean-square variation in the basis weight of the sheet.

Abstract: OUTPUT SPEED SENSOR DIAGNOSTIC CONTROL FOR A MOTOR VEHICLE TRANSMISSION     Abstract of the Disclosure A transmission diagnostic control effective when there is an apparent loss of the transmission output speed signal for determining if failure is real, and if so, the cause of the failure.  When an apparent loss of the output signal is observed, the transmission is successively upshifted through its various forward speed ratios while the transmission input speed is monitored to detect the occurrence of an upshift-related reduction thereof.  If the shifting fails to produce a reduction in the transmission input speed by the time the transmission has been shifted to the highest available speed ratio, a total transmission failure is indicated.  If the shifting produces a decrease in the transmission input speed, a total failure of the transmission is ruled out, and the diagnostic control determines if the failure is transmission or sensor related.  If the output speed signal is still absent and the input speed is high enough to generate vehicle motion, a speed sensor related failure is indicated.  If the output speed signal indicates normal vehicle movement, the diagnostic control is terminated and all forward ratios lower than the current ratio are indicated as failed.

Abstract: ABSTRACT            A method for the rapid preparation of a whole blood sample for photooptical analysis.  A whole blood sample, lytic reagent system and stain are contacted in a reaction vessel with gentle, asymmetric vortex mixing.  This method conserves the endogenous constituents of the sample, since the preparation of the sample occurs within a common vessel and any excess, unconsumed or unreacted, reagents and stain are not separated from the sample during preparation, thus avoiding the multiple wash steps traditionally employed.  The lytic agent preferably is acidic and stromatolyzes the erythrocyte fraction of the whole blood, leaving the leukocyte sub-populations in an unlysed, near native state.  The lysing can occur, before, simultaneous with, or after the staining in an elapsed time of 90 seconds or less.

Abstract: "Bit and Symbol Timing Recovery for Sequential Decoders"    ABSTRACT OF THE DISCLOSURE In a sequential decoding apparatus, a sequential decoder performs sequential decoding on convolutional code symbols stored in a data buffer according to the maximum likelihood algorithm. When the buffer is overflowed due to random noise, the sequential decoder skips a portion of the stored symbols, clears its internal state and initiates a stepwise decoding of newly arrived symbols. A sync detector detects that a count of symbols that have been decoded after the occurrence of the overflow is lower or higher than a predetermined value. If the overflow condition still exists following the stepwise decoding, a portion of the stored symbols is further skipped and the stepwise decoding is repeated. If the overflow condition ceases to exist and if the decoded symbol count is still lower than the predetermined value, the symbol skipping and stepwise decoding are repeated until it becomes higher than the predetermined value to cause the sequential decoder to resume normal operation.
