Patent EP-0292829-A2 (EP)
Inventor: EIBAND KARL
IPC: B60T15/04
Filed: 1988-05-16
Abstract: A dual circuit brake valve, particularly foot-operated brake valve for brake installations of vehicles, works with a pressure limitation on the first and second circuits; this prevents a supply high pressure on the first or the second circuit being fully applied, that is it is able to act as a modulated pressure in the respective brake circuit. For the purposes of limiting high pressures, both the foot-operable piston on the first circuit and the relay piston able to be subjected to the modulated pressure of the first circuit are each fitted with an auxiliary piston (45, 29) which, under the action of a pretensioned spring (47, 35), acts with a valve seat (12, 28) formed on it against the inlet and outlet valve arrangement of the first or second circuit. Also provided between the first and the second circuit is a mechanical application which, if the first circuit fails, allows mechanical actuation of the valve arrangement of the second circuit. <IMAGE>

Abstract: In a servo controlled device such as a disk drive actuator or a robot that is driven by a DC motor and must seek from one position to another position and settle at the target position in a minimum time, a deadbeat control response can effect settling in a minimum number of servo sample times with no steady state error and no ripple between sampling instants. The device design, initial conditions entering the deadbeat controlled mode and the frequency of servo samples can be used to enable deadbeat control by limiting the control current to a value that will not saturate the motor coil or exceed the linear operating range of the controlled device.

Abstract: A digital data transmission system wherein digital data channels are serially multiplexed and in which channel identification is encoded by displacements of zero crossings of the multiplexed data. The multiplexed data stream is differentially encoded so that data bits of one significance are represented by the presence of transitions in the transmitted signal at predetermined times and data bits of another significance are represented by the absence of transitions at said predetermined times. The differentially encoded signals are added to a clock at half the interleaved bit frequency so that the rising and falling edges of the bits are advanced and retarded according to their bit position. The multiplexed data with added clock is then high-pass filtered and linearly added to band limited auxiliary data before transmission.

Abstract: The number of registers (101) allocated to each register window (module) is stored in the memory means (108). Which registers, i.e., how many registers constitute each module is determined in dependency upon the number of allocation. Accordingly, how many registers (101) constitute each module varies in dependency upon the number of allocation in the memory means (108). Namely, in accordance with individual procedures on the program, a working register used on that procedure is determined and the number of registers constituting the working register is determined. 
     In addition, in this invention, memorization of the number of registers allocated to each register window in the memory means is automatically carried out on the basis of address information for a working register. Alternatively, memorization of the number of allocation is carried out on the basis of one of instructions that CPU can execute.

Title: Echo canceller having FIR and IIR filters for cancelling long tail echoes
Inventor: KOIKE SHIN ICHI C O NEC CORPOR
IPC: H04B3/23
Filed: 1990-02-23
Abstract: An echo canceller comprises a finite impulse response filter (6) connected to the incoming port of a hybrid (1), and a tail canceller (7) which includes an infinite impulse response filter (24; 40) having a multiplier (14; 33) for recursively multiplying an output digital symbol from the tapped-delay line (8) of the FIR filter with an attenuation coefficient R. A digital symbol from the IIR filter or one from the tapped-delay line (8) is multiplied with a tap-weight coefficient C i  and summed with the outputs of tap-weight multipliers of the FIR filter to produce a replica of an echo symbol, which is subtracted from a digital symbol y n  from the outgoing port of the hybrid (1), producing a residual echo symbol e n . The coefficient C i  is derived from correlation between residual echo e n  and a symbol from the tapped-delay line. In one embodiment, symbol from the tapped-delay line is further delayed (17) for a unit interval on the one hand, and multiplied (18) with coefficient R on the other, the difference between them being detected (19) and multiplied (20) with a coefficient K, which is either sgn(C i ) or 1/C,, to generate a multiplied difference. Correlation is detected (22) between the difference and residual echo e n  to derive the coefficient R. In a second embodiment, symbol from the tapped-delay line is further delayed (36) for a unit interval and multiplied (37) with K to produce a delayed-multiplied symbol. Correlation is detected (35) between it and residual echo e n  to derive the coefficient R.
