Title: Data streaming between peer subsystems of a computer
Inventor: MENDELSON RICHARD N
IPC: H04N21/434
Filed: 1995-06-29
Abstract: A data handling arrangement for a computer system, with particular application to multimedia systems, allows device adapters (control units) attached to the system to autonomously (without interrupting the system processor) control processing of a data stream of arbitrary length through memory buffers which are smaller than the stream. In this (stream processing) operation,  data constituting the data stream flows through devices controlled by the adapter in succession, and is held in shared memory buffers as it passes between devices. The adapters are prepared for the stream processing operation by a system processor, indicate their preparation status to the processor, receive  an initiating  signal  from the processor,  and then proceed to direct the operation to completion without further assistance from the processor. In the operation, the adapters coordinate usage of the memory buffers by respective devices. Coordination is accomplished using a notification signalling protocol  defined  during  preparation  of  the  adapters.  For notifying each other of buffer events (filling, emptying, etc.), the adapters use a peer communication feature of a system channel which connects the adapters and devices to the system processor and memory.  This  feature permits one  adapter to directly  communicate  "notification"  information  to  another control unit without involving the system processor. Information furnished to the adapters during their preparation includes descriptors defining the memory buffers and the notification protocol.  It also may include descriptors enabling a control unit to synchronize the processing of data in a stream with events external to the stream; e.g. an external timer function or events associated with the processing of another data stream.     Thus, for instance, video and audio components of a live motion picture presentation could be synchronized.  The controlling functions affecting stream processing are isolated from the controlled devices, and the processing functions performed by each device on data in a stream are performed independent of the functions performed by any other device relative to the same stream; thereby simplifying development of new devices and new processing functions.

Patent CA-2156559-A1 (CA)
Title: Hydraulic circuit for automatic control of a horizontal boring machine
Inventor: KEATING DONALD J
IPC: B23Q5/26
Filed: 1995-08-21
Abstract: A hydraulic circuit (10) is disclosed for use in controlling a horizontal boring machine which requires hydraulic fluid under pressure for rotating a drill bit or back reamer through a rotation circuit and hydraulic fluid under pressure for thrusting the drill bit or backreamer within the bore hole through a thrust circuit. Pressures from both the thrust circuit and control circuit are combined through restrictors in a mixing zone or area (26). The control port of a diversion valve (32) is connected to mixing zone (26) . When the combined pressure in the mixing zone exceeds the adjustable spring bias on the diversion valve, the diversion valve will open, diverting fluid from the thrust circuit to a low pressure zone. This will cause a reduction in the pressure in the rotation circuit as well. The reduction of both pressures will reduce the combined pressure in the mixing zone (26), causing the diversion valve to close and the pressures to increase. The hydraulic circuit maintains a constant maximum output for both circuits for a given horsepower input to the boring machine and productivity is enhanced due to reduced operator fatigue.
