Filed: 1983-11-30
Abstract: A unitary disposable conduit extends from the intravenous reservoir along a gravity-flow path to the patient, and incorporates a valve block containing an externally controlled flow-control valve. An electronic controller monitors the drop rate in a drop chamber which is an integral part of the disposable conduit, compares this rate with an operator-selected rate, and controls the valve by varying the current in a shape-memory actuator element whose movements, caused by the resultant Joule heating, are coupled to the valve to proportionally vary the flow rate in the conduit. The valve block is securely received within a recess in the controller, and is automatically coupled to the controller when inserted within this recess. The shape-memory actuator element may be incorporated within the disposable valve block, or may form a part of the controller, with a simple mechanical coupling to transmit its movements to the valve. The valve may be automatically or manually closed when the valve block is removed from the controller, or if power failure occurs.

Abstract: An endoscope sheath having a flexible tube surrounding the elongated core of an endoscope. The flexible tube has a transparent window near its distal end positioned in front of the viewing window of the endoscope. Channels for taking biopsies, injecting air or injecting water to wash the window of the sheath may extend along the endoscope, either inside or outside the sheath. Where the channels are positioned inside the sheath, they may be inserted in a longitudinal groove formed in the endoscope core. The protective sheath may be used with either end-viewing endoscopes or side-viewing endoscopes. In the latter case, the channel for taking biopsies extends through an elongated elastomeric membrane so that a catheter through the biopsy channel may be moved longitudinally by manipulation of an elevator. The protective sheath may be installed by rolling the elastomeric tube into an annular configuration and then unrolling the tube over the core of the endoscope. Alternatively, the tube may be inflated in its unrolled configuration to expand the tube and allow it to be easily slipped onto the endoscope core. A variety of specialized endoscopes may be created by using protective sheaths having a variety of special purpose medical instruments mounted at the end of a biopsy channel and operated through the channel.

Abstract: PURPOSE:To judge any abnormal operation of a control switch surely as well as to secure safety driving by installing an abnormal judging part for judging that an abnormal condition has occurred in operation of the control switch in the case where time detected in a phase time detecting element becomes more than the specified time, in a control part. CONSTITUTION:An actuator 22 for a hydraulic valve selecting a running range of an automatic transmission is controlled by a control means 30. A shift operating means for outputting a range select command to this control means 30 is provided with a stroke contact type control switch 18 on which are setting running range is parallelly installed on the specified locus in regular succession, and this control switch 18, in turn, has a signal generating means outputting a multistage signal, having a phase difference, as a range select command according to operation of this switch. Time generating this phase difference is counted by a phase time detecting element of the control means 30, and when this time becomes more than the specified time, a fact that an abnormal state has occurred in operation of the control switch 18 is judged by an abnormal judging part.

Abstract: A general purpose interface is provided to a file system of a multimedia server for improving datastream throughput by avoiding data copying and context switching. The file system includes an export registration service providing function pointers to the file system's implementation of a predefined set of zero copy interfaces. These interfaces include an initialization service to set up necessary data structures and to place use counts on objects to prevent them from being removed while zero copy operations are in progress. A termination service in the zero copy interfaces cleans up data structures and removes use counts. Additional services validate that a specified file is suitable for zero copy operations, find and record file attributes needed to later acquire buffers at interrupt level. A data structure is defined to hold these attributes for subsequent calls. Another service locks a buffer at an interrupt level and returns the amount of data present, and provides addressability to the buffer in another address space context. A data structure holds these buffer attributes for subsequent calls. A service is additionally provided to unlock the buffer at interrupt level. Finally, a service provides information on changes to the access pattern of the file such as would be needed to support VCR functions. A hash chain emplyoing a singly linked list updated atomically allows for safe buffer lookups at interrupt level. Compare-and-swap locking faciliates this. A mailbox interface useful at interrupt leve provides prefetch and release information to the daemon. In case of a lock collision or where the buffer is not available, the buffer is acquired in a process context. <IMAGE>
