摘要： A frame stripping algorithm for use in a ring communication network utilizing early token release wherein multiple frames can exist on the ring at one time. The algorithm introduces two new strip terminating conditions which supplement two of the three conditions applicable to a normal token release scheme. The first of these conditions occurs when the source address in a received message is not the same as the receiving station's address and no code violation errors have been detected. The second condition occurs when the receiving station detects an isolated ending delimiter without a preceding starting delimiter.

摘要： A method and apparatus for enabling the transmitter to decide the number of variable length frames that can be trasmitted within the token holding timer (THT) window. The last frame decision algorithm enables the transmitter to set the intermediate frame bit in the ending delimiter to the right state to indicate the status of each frame in the transmitted frame sequence. A look-ahead technique is used to check the remaining transmit time available in the THT time window, therefor, no ring bandwidth is wasted on partially transmitted aborated frames, effectively optimizing the throughput of the network. Since key variables in the last frame decision algoritm are softwar programmable, the algorithm is independent of ring speed. The algorithm counts transmitted octets instead of measuring transmission time in deciding whether to transmit an additional frame. The algorithm can be applied to either signal frame or multi-frame transmit mode and to either normal or early token release. It is applicable to both the IEEE 802.5 local area network standard for token ring networks and the AnSI X3T9.5 standard for FDDI.

摘要： An air bag system to protect occupants of automobiles against injury in case of collision. An air bag is housed, when empty, in a tapered open container in the passenger compartment of the car. It is inflated by compressed air from an air tank in the vehicle. Inflation is controlled by solenoid valves actuated by switches responsive to excessive brake pedal pressure, harness tension, or force against the front bumper. The speed of inflation may vary. A manual switch controls a deflation pump which deflates the bag and also mechanically draws it back into its container. Normal repeated use of the brake pedal operates air pumping means to keep up the pressure in the air tank.

摘要： An adaptive regeneration system is provided for reconstructing a signal received in the form of a multi-level composite data and clock signal which has been degraded with respect to amplitude and timing. The system includes a local clock circuit for outputting a plurality of phase-delayed local clock signals, and a clock recovery circuit for receiving the received multi-level signal and the plurality of phase-delayed clock signals and extracting a phase-delayed local clock signal which most accurately represents the phase shift between the received multi-level signal and the local clock signal. A threshold level selection circuit receives the extracted phase-delayed local clock signal and the received multi-level signal and outputs in real time a data amplitude reading and a plurality of multi-level threshold levels corresponding to the amplitude levels of the received multi-level signal. A data regenerator receives the data amplitude reading, the plurality of multi-level threshold levels and the extracted phase-delayed signal and reconstructs and outputs the received multi-level signal essentially in its originally transmitted form.

摘要： A multi-frame stripping method for use in a token ring network utilizing early token release with multiple frames transmitted by multiple stations circulating around the ring. The method recovers the ring with minimum loss of data after detection of an error condition resulting in frame corruption. The transmitting station is responsible for removing its own frames from the ring. With one or more of its frames corrupted, a station terminates frame removal after the transmitter has finished transmitting when a frame is received from another station without code violation errors in the frame header if the frame counter has returned to its initial value. The station terminates stripping when only a single frame is transmitted and then becomes corrupted if an isolated ending delimiter is detected at the station. The station also terminates stripping in the multi-frame case when the ending delimiter of the last frame transmitted by the source station is received without code violation error in the I-bit, if each preceding ending delimiter is correctly detected regardless of data corruption occurring in any frame header. The method is applicable to the IEEE 802.5 and ANSI X3T9.5 (FDDI) standards.

摘要： A method and apparatus for preparing a moving vehicle for impending impact with another vehicle or object which incorporates the extending of the air bag to fill in the space between an extendible bumper. A detection apparatus senses a dangerous speed of the vehicle or an approaching object in the path of the vehicle and extends the bumper forwardly or rearwardly from the body of the vehicle while at the same time filling the space between the body and bumper with an inflated air bag. Should the impact not take place, or the dangers facing the vehicle have decreased, the apparatus retracts to its initial inoperative condition. One form incorporates a first filled bag which is filled at all times, and then a second bag which is inflated when the bumper is extended. A modified form moves an elongated bag into position with its longer dimension filling the space between the body of the vehicle and the bumper, and correspondingly returns the bag so that its shorter dimension fits in between the retracted bumper and the body of the vehicle.

摘要： A network interface card for attaching computers, work stations or the like to a Local Area Network (LAN) includes a device which indicates an address compare if selected bits in a first part of an address, in the address field of a received frame, matches bits stored in the network interface card and at least one bit of a code word stored at a particular address of an index RAM is set to a predetermined state. The particular address in the index RAM is identified by a second part of the address in the received frame. The range of address which can be recognized is further extended by a contents addressable memory (CAM) coupled to the device. The CAM makes a parallel compare between an input address and its contents and outputs a match signal if a match is found. A programmable control register is used to activate or deactivate the CAM or the device.
