Patent EP-0341986-A2 (EP)
Inventor: FARR GLYN PHILLIP REGINALD
IPC: B60T8/1766
Filed: 1989-05-09
Abstract: Fluid is adapted to be released from a brake (11) to an expansion chamber (24) from which a pump (4) is adapted to withdraw fluid to achieve automatic re-application to the brake. The system includes an inlet valve (21) between a master cylinder and the brake (12), a re-application valve (22) between the pump and the brake, and a dump valve (23) between the brake and the expansion chamber (24). The three valves are solenoid-operated and are operable in a predetermined sequence by a control module responsive to signals from means (17) responsive to the behaviour of a wheel (12) braked by the brake. 
     Brake re-application pressure may be held in a "hold" mode by closing the re-application valve (22) to prevent the pump from increasing the pressure within the brake. 
     In a modification a separate, additional, hold valve (53) may be provided to isolate the expansion chamber (24) from the brake.

Abstract: A low frequency pilot signal having predetermined positive and negative excursions is applied to an electrical modulation signal input (26) of a Mach-Zehnder electro-optic modulator (18) together with an electrical input signal. A bias voltage VB selected to bias the modulator (18) at a linear point (Vπ/2) is also applied to the signal input (26). The optical output signal of the modulator (18) is sensed, and the magnitudes of the positive and negative excursions of the output signal which correspond to the positive and negative excursions of the pilot signal are compared with each other. If the modulator (18) is linearly biased as desired, the excursions will have the same relative relationship as the excursions of the pilot signal. If the modulator (18) has drifted away from the linear bias point (Vπ/2), one excursion will have a larger magnitude relative to the other than in the pilot signal, indicating the direction of deviation. The bias voltage VB is automatically adjusted toward the linear bias point (Vπ/2). Where the bias voltage range includes a plurality of linear bias points (Vπ/2) within the limits thereof, the voltage difference (2Vπ) between two of the linear bias points (Vπ/2) is automatically measured at startup. If the modulator (18) drifts into one of the limits, the bias voltage VB is reset to a value spaced from the respective limit by the voltage difference (2Vπ), thereby automatically resetting the bias voltage VB to another linear point (Vπ/2) within the range.

Abstract: The invention relates to a method and apparatus for coding speech signals as digital signals having a low bit frequency. The invention is characterized 
■ in that the analog signal is converted into a first pulse signal composed of pulses at a mutually equal time interval, the pulse amplitude of said pulses corresponding to that of the analog signal at that instant; 
■ in that the first pulse signal is converted into a series of p second pulse signals which are each likewise composed of a fixed number of pulses at a mutually equal time spacing which is, however, a multiple of that of the first pulse signal, while the pulse amplitude likewise corresponds to that of the analog signal at that instant, 
in which connection, of the successive second pulse signals of said series, the position of the first pulse of the respective second pulse signal, viewed in the time domain, is shifted in time with respect to the start thereof over a spacing equal to a multiple n of the said   time spacing of the first pulse signal, n successively increasing from 0 to p; 
■ in that that second pulse signal whose correspondence to the first pulse signal is the greatest is selected from the various second pulse signals and that a first control code for assembling the synthetic signal corresponding to the analog signal is generated in accordance with the time spacing between the start and the first pulse of said selected second pulse signal; 
■ in that the said first pulse signal is compared with a set of various third pulse signals which are each composed of pulses at a mutually equal time spacing equal to that of the second pulse signals, which pulses have various pulse amplitudes and in which connection, of all said third pulse signals, the position of the first pulse of the respective third pulse signal, viewed in the time domain, is shifted in time with respect to the start thereof over a spacing which is equal to that of the selected second pulse signal; 
■ in that that third pulse signal whose correspondence to the first pulse signal is the greatest is selected from the said set and that a second control code for assembling the synthetic signal corresponding to the analog signal is generated in accordance with the order number of said selected third pulse signal. Instead of comparing the first pulse signal with the various third pulse signals from the said set (after which said third pulse signal whose correspondence to said first pulse   signal is greatest is selected from said set) it is also possible (and preferable) for the (previously) selected second pulse signal to be compared with the various third pulse signals (after which that third pulse signal whose correspondence to said selected second pulse signal is the greatest is selected.

Abstract: Methods and apparatus for encrypting and subsequently decrypting an analog or digital signal are disclosed. During encryption the signal waveform is transformed by a substantially continuous non-linear complex function of frequency. The transformation is characterised in that the time duration of a transformed impulse signal is substantially increased. Decryption requires transformation of the encrypted signal by substantially the complex inverse of the encryption function. The transformations may vary in time during encryption/decryption of a signal.

Abstract: In known compressed air systems of this kind, the low pressure part is supplied via a pressure relief valve arrangement. Known pressure relief valve arrangements close gradually as the pressure in the low pressure part approaches the value of the low pressure and thereby cause repeated switching on and off of the pressure generator, resulting in high stress on the components involved. To eliminate this disadvantage, the invention proposes the arrangement of a closing device (10) on the pressure relief valve arrangement (11). In one embodiment, the closing device is actuated by the high pressure which brings about the switching off of the pressure generator (1) and, in another embodiment, it is actuated by the drop in the delivery pressure of the pressure generator when the latter is switched off. One area of application of such a compressed air system is in non-track-bound utility vehicles. <IMAGE>
