摘要： A method and apparatus for synchronizing digital chronometers is provided in a distributed digital system having a number of nodes and a global clock for generating clock pulses. A subset of those nodes is coupled to a corresponding synchronizer while other nodes with chronometers are coupled to other synchronizers. Each synchronizer is coupled to at least one other synchronizer and receives clock pulses from the global clock and includes a counter holding a count. A sync signal is propagated in a forward direction from a first synchronizer to a last synchronizer through a chain of synchronizers. The sync signal is received and thereafter the synchronizer count is incremented at each received clock pulse. At the last synchronizer, the asserted sync signal is propagated back as an echo signal in a reverse direction from the last synchronizer to the first synchronizer through the chain of synchronizers. After receipt of the echo signal at a synchronizer, the synchronizer count is halted. Eventually the echo signal is received at the first synchronizer. After receipt of the echo signal at the first synchronizer, a decrement signal is propagated in the forward direction. At each synchronizer after first receipt of the decrement signal, a divided count is decrement upon receipt of each subsequent clock pulse. The divided count is one-half of the count immediately after the count was halted after receipt of the echo signal. When the divided count is decremented to zero, the chronometer associated with the synchronizer is started.

摘要： A parallel processing computer system having an improved architecture for communication of information between nodes. The computer system of the present invention comprises at least three nodes; each of the three nodes for processing information. Each of the nodes comprises a routing means for routing information between nodes. The routing means allow reservation of a route through the network of nodes. Messages may then be transmitted from an origin node to a destination node over the reserved route. Use of a route reservation system reduces requirements for buffering of information at intermediate nodes on a route, improves message passing latency and increases node-to-node bandwidth. The present invention teaches communication of messages between nodes in a synchronous manner.

摘要： An adaptive routing means and method useful for transferring messages on a number of multi-dimensional network topologies that connect distributed multi-processing systems. A plurality of processing nodes comprising processing means for processing information and router means for routing messages are connected in a multi-dimensional network (A) with an identical or redundant message passing multi-dimensional network (B) of routers being connected to network A. Each router comprises four types of channels for message passing: 1) a channel to transfer information between a router and a processor coupled to the router, 2) a channel to transfer information in an X direction, 3) a channel for the Y direction, and 4) a channel for the Z direction. This connectivity allows messages to pass between nodes within network A, between routers within network B, or between network A and network B by passing through a router. Messages are routed in networks A and B by routing first in the X dimension and then in the Y dimension. The present invention transitions between A and B networks when contention is encountered in the X or Y direction, if the appropriate Z channel is available. If an X or Y channel is not immediately granted, a request is made for the Z channel. Both the request for an X or Y channel and the request for the Z channel are maintained until one request is granted. The message is then routed on the granted channel and the other request is withdrawn. The router does not commit to routing on a particular channel until one channel is available.

摘要： An electronic system is disclosed that is particularly useful for synchronizing motion picture and sound recordings. The system includes a sensor that is positioned contiguous to a movie camera during filming and contiguous to a movie projector during film playback to sense a characteristic indicative of film movement and, responsive thereto, producing an electrical output signal. During filming, a sensor, such as a microphone or induction coil, may be positioned contiguous to the movie camera such as by placing the sensor in a cylinder screwed into a camera tripod socket. During playback, the sensor, such as a light sensor, may be positioned to sense light bursts of a running movie projector. A control unit receives the electrical output signal from the sensor and utilizes the same in controlling operation of an associated tape recorder. During filming, the control unit controls operation of the associated tape recorder and causes a timing signal to be recorded on the tape for synchronizing purposes with sound associated with the motion picture also being recorded on the tape recorder. In the control unit, the electrical output signals produced by the sensor during filming is processed utilizing envelope detection as well as filtering in a band pass filter to produce the desired timing signal for synchronization purposes. During playback, the electrical output signal from the sensor and the timing signal from the tape recorder are processed and coupled to counters the output from which controls operation of the tape recorder to automatically achieve and maintain synchronization of picture and sound during playback.

摘要： A method and apparatus for reserving and releasing routing paths in a parallel processing computer system. The present invention eliminates the need to restart the computer system to recover from a system seizure or an application stall. A plurality of signals are provided which convey various message transmission information to source, intermediate and destination nodes and routing elements. A first signal is used by a source node to reserve a route to a destination node. A second signal is used by the destination node to indicate that the message has reached the destination node and later that the entire message has been transmitted. A third signal is used by the destination node to signal that an error in transmission has been detected. Through various combinations of the signals transmission information is obtained and nodes in the route may be reserved and released.

摘要： A conical contact of a male plug is biased by a coil spring which rides on a cylindrical tail. A bushing compresses the spring, but is held captive on the tail by a pin passing radially through the bushing and a slot through the tail. A female receptacle has a conical hole to receive the conical contact. A sleeve extends from the hole, providing two ramp shaped slots to engage the protruding ends of the pin on the male plug. When the connector is mated, the bushing is inserted into the sleeve and the ends of the pin engage the slots in the sleeve, causing the conical contact to enter the conical hole. Rotation of the bushing causes the ends of the pin to ride the ramp shaped slots inward, causing the conical contact to rotate as the spring compresses, forcing the conical contact into the conical hole. When fully mated, the ends of the pin fall into detent positions at the ends of the slots, locking the connector. Biased by a spring, the matching tapers of the conical contact and conical hole provide a low-resistance, high-current non-compliant connection, while the detents lock the connector, eliminating accidental dis-connection.
