  • State machine bus controller providing function and timing parameters to satisfy requirements of asynchronous bus and more than one type of device on the bus
    Patent number: 5944799
    Abstract: A state machine bus controller for interfacing the CPU of a micro-computer based system with memory and I/O device is described. The controller, while capable of interfacing with a bus which is synchronous in nature, can maintain synchronous handshake with more than one type of microprocessor while providing function and timing parameters to satisfy requirements of an asynchronous bus and more than one type of device which reside on the bus.
    Type: Grant

  • Apparatus and methods of detecting injection in a diesel engine
    Patent number: 4090404
    Abstract: The invention relates to an apparatus for detecting the injection into an internal combustion engine, and in particular a diesel engine, comprising an injection pump, by means of an injector and at least one length of connecting tubing between the pump and the injector, this apparatus comprising means for detecting the transverse deformation of the connecting tubing under the pressure of the injected fuel.The detection means are disposed between gripper means for firmly locking the connecting tubing at two non-contiguous zones, and are carried by these gripper means in such a way that the sensitive parts of the detection means are applied, in the operative position of the apparatus, at least to the central part of the tubing between these two zones.
