Title: Variable torque clutch control
Inventor: DANIELS JOHN
IPC: F16D37/00
Filed: 1989-09-26
Abstract: A method of remotely controlling torque transfer from a rotatable shaft (S) to a surrounding core via a variable torque clutch, makes use of a variable clutch mounted on the shaft between the shaft and the core, a primary power supply to cause torque transfer by the clutch and carried to the clutch via the shaft (S) and a secondary supply including a coded signal also carried by the shaft to the clutch to allow remotely controlled variation of the magnitude of torque transferred. By using a coded signal, which may be superimposed on the power supply it is possible to control independently a plurality of clutches on a single shaft whilst using the shaft to carry a common primary power supply. In one embodiment an electro- rheological fluid is located between electrodes (H) and (F), the inner body of the clutch engages the shaft (S) by a key (J), and the outer body (A) drives the core via a gripper mechanism such as a friction plate, the torque transfer being controlled by electronic means (G). Alternatively the clutch may be controlled by an electro-pneumatic transducer, the primary power supply being provided by a high pressure air line. <IMAGE>

Title: Knocking detection system for an internal combustion engine
Inventor: SOGAWA YOSHIYUKI
IPC: G01L23/22
Filed: 1992-01-30
Abstract: A knocking detecting system comprises a microcomputer with an A/D converter 4 which receives a frequency signal processed in accordance with the vibration signal of a knock sensor 1. The microcomputer carries out the A/D conversion steps (S1 - S4, Fig 2, not shown) of continuously sampling digital values, the steps (S5 - S9) of integrating the differences between the digital values and a background level over a detecting period, and the steps (S10 - S12) of comparing the integrated value with a judgement level, thereby to judge the presence of knocking and to evaluate a knocking level. The background level is determined by the microcomputer by averaging digital values from the A/D converter and a data number in a predetermined range, calculating a weighted average of the averaged digital value and multiplying the weighted average with a coefficient. Thus, the knocking is detected, and the background level is calculated at high precision. <IMAGE>

Abstract: An SS communication device useful for suppressing demodulation errors to a minimum value, oven if there exist a plurality of narrow band disturbing signals, is disclosed. In the transmitter (T), a first PN code (i) from a first PN code generator (1) and a second PN code (ii) having a delayed phase coming from a shift register (3) are inputted to an MPX (2) and switched according to an exclusive logic sum of data (xxii) coming from an EOR (17) with a disturbing signal. In this way an HF signal is modulated by a modulator to be transmitted. In the receiver (R), a correlation output (viii) from a correlator (9) is detected by a detector (12) and a detection output thereof is digitized by a voltage comparator (13). A correlation pulse (xii) thus obtained is applied to AND gates (14, 15). Time window pulses are applied to MPXs (18, 19) and switched by a control signal to also be applied to these AND gates (14, 15). Pulses (xv, xvi) from these AND gates (14, 15) are counted by an up- and down-counter (16) in a demodulating circuit to demodulate the data. <IMAGE>

Title: Resynchronization of encryption systems upon handoff
Inventor: DENT PAUL WILKINSON
IPC: H04L9/00
Filed: 1992-12-18
Abstract: A system for the synchronization of encryption (203, 206) and decryption (204, 205) in a duplex cellular radio system in which an encrypted call (203, 206) may be switched from one cell to another. At the instant of handoff, a rapid first resynchronization means temporarily seizes the voice channel in one direction only and transmits synchronization information in such one direction. The first resynchronization means ceases to transmit the synchronization information and releases such one direction of the voice channel as soon as an indicator of successful resynchronization is detected in the other direction. Transmission of speech traffic in such one direction is then resumed after such detection of successful resynchronization. To avoid occupying such one direction with continuous transmission of the synchronization information in the event successful resynchronization has occured but has not been detected due to faulty transmission in the other direction, an upper limit is set on the length of time which the first rapid synchronization means may cease such one direction. After such timeout, resynchronization information may be provided by a second resynchronization means at a slower rate through a slow rate control channel bit stream which is multiplexed (209 & 211) with the traffic data. <IMAGE>
