Title: Hydraulic drive system
IPC: B23Q5/00
Filed: 1988-10-15
Granted: 1991-01-16
Abstract: A hydraulic drive system for a punching or an embossing tool comprises a double-acting hydraulic drive cylinder with piston surfaces of various sizes. The fast feed, working feed and fast retrun are controlled by the joint or alternating application of pressure by the piston surfaces. For this purpose, a surface-switching valve switches over from differential drive to unilateral application of pressure to the largest drive surfaces when the drive pressure exceeds, for example, 90 % of the maximum output pressure of the pressure supply aggregate. The surface-switching valve comprises a nonreturn valve which is acted on in the direction of opening by the working pressure prevailing in the smallest drive pressure chamber. The elastic closing force of the nonreturn valve is equivalent to an opening pressure equal to approximately 90 % of the supply pressure. The surface-switching valve comprises a hydraulic slide valve with a valve body in the form of a differential piston which the body of the nonreturn valve. When the nonreturn valve is closed, the pressure acts on the smallest drive pressure chamber and the pressure prevailing in the largest drive pressure chamber acts on the largest step of the differential piston. The ratio of the surface area of the largest step of the piston to the area covered by the seat of the nonreturn valve seat is geater than the ratio of the largest to the smallest surface area of the piston of the hydraulic cylinder.

Title: Method and apparatus for speech signal detection
IPC: G10L11/02
Filed: 1989-04-25
Granted: 1992-12-16
Abstract: The method disclosed comprises the steps of: cutting up the signal into frames, sampling each frame to obtain a digital signal comprising a determined number n of samples, pre-emphasizing the digital signal, filtering the pre-emphasized digital signal by means of a high-pass digital filter to obtain a filtered digital signal, measuring, in each frame, the maximum energy of the pre-emphasized signal and the maximum energy of the filtered digital signal, to achieve an energy ratio R between the maximum energy of the filtered digital signal and the maximum energy of the pre-emphasized digital signal. The method also comprises the steps of computing, between two limits, the mean long-term values of the maximum value of the energy of the filtered signal and of the energy ratio and of computing, on the basis of the mean long-term values, four threshold values, two of them being maximum values, forming two lower limits of the speech state for the filtered signal and the energy ratio respectively, and two of them being minimum signals, forming two upper limits of the noise state for the filtered signal and the energy ratio respectively, to compare, with these threshold values, the maximum energy of the filtered signal and the energy ratio, to decide on the presence of the vocal signal in the noise-infested signal when the maximum energy of the filtered digital signal, or the energy ratio, is respectively greater than their maximum threshold values.

Abstract: A packet switch receives data and processes it for assembly into packages. A bus allows communication between each of the data processing units of the switch and one or more storage units for storing the data packets. Arbitration for deciding which of the processing units will be granted access to the bus is performed by a system which selectively and alterably designates any of at least two different levels of priority of access to the bus for each of the processing units, and the relative percentages of time of access for the different priorty levels. The system assures greater access to the bus by those of the processing units having the higher level of priority. If communication is provided by two buses, the requests for access are alternated between them. The arbitration system provides selective access to the bus in any of a plurality of bus cycles including a read cycle, a write cycle and a read/modify/write cycle, and grants a request for access from a higher priority processing unit within one bus cycle.
