Abstract: A hydraulic brake master cylinder (10) and a pneumatic-hydraulic brake booster (11) arranged to one side of this together form a control device. The brake master cylinder (10) contains at least one hydraulic pressure chamber (41) which has a connection (53) for a brake circuit and is defined by a mechanically controllable main brake piston (43). A hydraulic auxiliary chamber (74), which is defined by an auxiliary piston (73), is assigned to the brake master cylinder (10). The brake booster (11) contains two pneumatic booster chambers (17, 18), which are separated from one another by a movable wall (15) and when the brakes are operated can be connected by a control valve (70) to sources at different pressures. A booster piston (28), which can be driven by the movable wall (15) in the brake booster (11), defines a hydraulic servo chamber (31). This is connected to the auxiliary chamber (74) so that the pressure in the servo chamber (31) acts via the auxiliary piston (73) to boost the brake force on the main brake piston (43). The control valve (70) is arranged to the side of the brake booster (11) on the brake master cylinder (10), can be mechanically operated together with the main brake piston (43) and is connected to the two pneumatic booster chambers (17, 18) by a respective control line (21, 22). As a result the brake booster (11) can be accommodated anywhere in a vehicle. <IMAGE>

Abstract: A method for determining the total time of flight distance of a light pulse from a generator on a moving airborne platform (1) to a target (6) at or near ground or sea level involves triggering a pulse of primary light radiation from the generator (2) towards a surface (6) at or near ground or sea level. The beam is sufficiently intense and of such spectral composition that the beam causes the surface to absorb light radiation. The secondary light backscatter or the reflected primary radiation backscatter is detected and the outgoing primary light radiation and the returning secondary radiation or the reflected primary radiation are used to operate triggers (25,28) on the start and stop inputs of a timer (21) to determine the time of flight of the light pulse from the airborne platform to the target and back again. The total time of flight distances are used to determine the timing of the opening of the shutter or the optical detector gating of the subsequent pulse before the return of that pulse of induced secondary radiation or reflected primary radiation, and, thus, to circumvent the minimum propagation delay in the electronic circuitry.

Abstract: A novel system (10) for determining the magni­tudes of loads on rotating helicopter components (12) from signals remotely measured on the helicopter fuselage (18) is characterized by a processor (20) which decomposes the measured signals into corresponding Fourier components and extracts selected components therefrom. A programming module (44) performs a multiplication on the respective Fourier components to correlate the measured components with corresponding determinative parameter values. The parameter values are established in a calibration process which is characterized by determination of the independent values of a measured signal set using a Jones orthogonal­ization process. The signals output from the coefficient programming module (44) are provided to a multiplying resolver (48) which receives synthesized reference sinusoids from a digital processor (38) and generates time dependent signal components therefrom. These signals are ultimately summed in an analog summer circuit (52) whose output signal corresponds to the desired parameter signal.

Abstract: There is provided according to the invention a method and apparatus for eliminating or minimizing the error due to amplifier offset or drift error in an integrating dual slope analog-to-digital converter. The converter is provided with a switching and control arrangement whereby the integrating capacitor is charged for one-half of the predetermined charging time as a function of the sum of the levels of the unknown signal and the error signal. The integrating capacitor is charged for the remaining half of the predetermined time period as a function of the difference of the levels of the unknown signal and the error signal so that the capacitor reaches a level of charge which is a function of the level of the unknown signal substantially unaffected by the level of the error signal. During deintegration of the capacitor by a reference signal the polarity of the error signal is inverted during successive or consecutive deintegration cycles so that the error voltage is self-cancelling in two successive deintegrations and is eliminated from the summed digital output.

Abstract: A method for maintaining the integrity of ties and their associated tie groups in a CPU-based, layered communications subsystem in which the connection endpoints in each layer are denoted by a connection control block (CCB), the relationship between CCBs being denoted by ties. Ties and their CCBs can be mapped onto an edge-oriented graph of tie group relations. The arbitrary removal of an edge (tie) in the graph compro­mises graph integrity by possible formation of unenumerated subgraphs or independent graphs. 
     The solution involves enumerating those edges having vertices which no longer reference CCBs within the tie group, removing them, and forming a second tie group. The enumera­tion is conducted over a Eulerian traverse of the remaining n edges of the graph. A Eulerian traverse of a graph is one which traverses each edge exactly once. Such a traverse reduces the number of comparisons M to a range N < M < O(N²). This facilitates maintaining either one or two tie groups per cutting of an edge in the graph.

Abstract: A method and structure for performing data synchronization by delaying the input data for substantially one-half of the VCO signal period and then comparing the phase of the delayed input data to the VCO signal. The phase difference is filtered and controls the frequency of the VCO signal to align the VCO signal with the delayed input data. The delayed input data is clocked into a flip-flop on the opposite phase of the VCO signal to produce an output signal. In a preferred embodiment the delay of the input data for phase comparison, and the delay of the input data for the output flip-flop can be independently selected.
