A fluid control system 10 and selector valve 24 for use therein, for controlling a plurality of fluid actuated elements 12, such as valve operators. The fluid actuated elements are controlled from an operating station 52, which is located remotely from the fluid actuated elements 12. Instructions regarding which of the fluid actuated elements 12 it is desired to operate are transmitted by coded signal from the operating station 52 to the selector valve 24, which is positioned proximate the fluid...

The invention relates to a device for reproducing coded keys adapted to machines for reproducing keys by scanning and comprising a rotary cutter and a follower adapted to be displaced simultaneously in two orthogonal directions, wherein said device comprises a support, a first carriage mounted to move with respect to the support, a second carriage mobile with respect to the first and bearing a bar provided with a single notch whose shape is that of the notches of the key to be reproduced, the tw...

The locking system comprises a magnetic key having a plurality of parallel rows of magnets arranged in a pattern one behind the other and forming a locking code of the magnetic key, and a reading device into which the magnetic key can be inserted in the direction of the rows of its magnets. The reading device comprises magnetic field sensors for the serial reading of the locking code formed by the magnets. A control circuit which compares the information of the read locking code with the informa...

A method of processing coded video, for example by inserting generated frames, or adjusting values in timing fields, or adjusting the time at which it is output, to adjust the timing of output of decoded video from a decoder receiving the coded video is disclosed, together with corresponding apparatus. The outputting apparatus may be included in a multiple-source video system, to enable multiple video sources to be synchronized. The output video can be synchronized to a studio reference clock.

A telephone access system provides to the caller connection to an output upon receipt of a coded signal from the caller. Units are connected in sequence for receipt of each member of the coded signal. The caller has a predetermined period of time to enter the correct code or the system automatically hangs up. The system described uses TOUCH-TONE and all components are state of the art.

Improved systems and methods for coded aperture imaging of radiation-emitting sources. According to one aspect, the present invention is directed to reducing and/or eliminating the artifacts that are inherent in previous near field coded aperture imaging systems such that the improved sensitivity and resolution of these systems can be practically utilized. A system and method of the present invention utilizes two projections of radiation from an object, the first through a first coded aperture m...

A receiver for use in deciding which signal points were sent from a transmitter based on corresponding noise affected signals received over a channel, the transmitter including an encoder which encodes a stream of information symbols into the signal points, the noise affected signals carrying information about a particular sequence of possible states occupied in a succession of time intervals by a finite state process. The receiver includes feedback circuitry for generating a plurality of differ...

A method and system for presenting time-based, comparative, patient-specific ECG data in various presentation formats, wherein color-coding is employed as a visual device to communicate vividly different, selected "changed" characteristics in that patient's current ECG-detected status.

An improvement to a modulation system of the kind in which the encoder selects a codeword corresponding to a plurality of modulation signal points on the basis of a block of digital data, the available codewords for a given block being independent of the signal points corresponding to the codeword selected for any other block. In the improvement a constellation of available signals comprises groups with equal numbers of signals, and an encoder is arranged so that the group from which at least on...

Apparatus for sending bits of information over a band-limited channel by modulating a carrier in accordance with a sequence of signal points drawn from a constellation of available signal points, in which the apparatus includes circuitry for accumulating groups of the information bits for encoding into the signal points, different groups having different numbers of information bits from a primary data source, and an encoder for encoding at least the bits of each said group into at least one sign...
