Abstract: A leak detection system and a method of detecting leaks are disclosed for detecting a leak in a system, including a pump, a dispenser, a conduit communicating the pump and the dispenser, and a valve in the conduit. The valve includes an electronic flow measurement device for detecting leaks in the system downstream of the device. 
     The system may be operated by a control circuitry, which indicates a predetermined flow of fluid indicating a leak. The present invention is also directed to a method of detecting a leak in a system having a fluid pump, a dispenser, a conduit connecting the pump and the dispenser, a valve in the conduit, and an electronic flow detection system in the valve. The valve is provided with an orifice communicating the conduit with the electronic flow detection system. 
     The method includes the steps of activating the pump and opening the dispenser to dispense a fluid, and then closing the dispenser while continuing the activation of the pump thereby increasing fluid pressure in the conduit. The increase in fluid pressure causes the valve to close, thus isolating the pump from the dispenser except for the orifice in the valve. The electronic fluid detection system senses the flow of fluid through the orifice.

Abstract: A computer system includes a plurality of central processing units (CPUs), a main memory, a system control unit (SCU) for controlling the transfer of data between the CPUs and the main memory, and a service processing unit (SPU) to interface the computer system with the outside world, such as an operator console. The method used for interfacing the SPU and SCU includes delivering a BUFFER FULL handshaking signal from the SPU to the SCU in response to the SPU receive buffer having data contained therein and being unavailable to receive data. The SCU responds to the absence of the BUFFER FULL handshaking signal by delivering a TRANSMIT FRAME handshaking signal to the SCU. A preselected duration of time after delivering the transmit frame, the SCU delivers the actual data in a series of fourteen consecutive clock cycles. Further, the method for delivering data from the transmit buffer of the SPU to a receive buffer of the SCU includes delivering a BUFFER REQUEST handshaking signal from the SPU to the SCU in order to determine if a buffer is currently available in the SCU. When a receive buffer grant becomes available in the SCU, a buffer grant handshaking signal is delivered to the SPU. The SPU responds by delivering the actual data in fourteen consecutive clock cycles.

Abstract: This invention relates to a method to establish a conference connection between a plurality of conference nodes (2, 4, 8) arranged in a telecommunication network (1); and also to a node design (30; Fig 3) of such a conference node. The conference according to this invention is set up on a per call basis. Any of the conference nodes (2, 4, 8) shall, each time it activates, access a free information resource (11) among a plurality of resources (11, 12,...,n) and transmit it's message to this resource; while all the conference nodes during all the conference time, are listening to the messages present on all the activated or occupied resources. The maximum number of active (i.e. transmitting) conference nodes correspond to the total number of information resources. The maximum number of passive (i.e. listening) nodes are unlimited. A node is typically moving from a passive state to an active state and back again to the passive state leaving the resource unoccupied. Each resource may preferably be designed as a ring connection via which all the conference nodes are interconnected as the ring is looped through passive conference nodes, but where each activated ring connection is broken, only at one place, but in a dynamic manner, at the input of the active node associated with just this ring, which active node accesses this particular resource during the activated time period of just this node. The invention is well suited for digital crypto conferences, as speech decoding and decrypting is undertaken at each conference node input, while encryption and speech coding is done at each conference node output. In addition the invention is easily adapted to an Integrated Services Data Network (ISDN). Echo suppression, as well as addition and subtraction of conference signals, are totally avoided. The crypto keys to be used in such a crypto conference, may be distributed among the conference participating nodes before the conference starts; and/or they may be altered during the conference, in short lasting pauses in the conference, or on a free resource, or via the D-channel in the ISDN implementation.
