Patent CA-2084886-A1 (CA)
Inventor: CAMBIER JAMES L
IPC: H05G1/60
Filed: 1991-06-07
Abstract: ABSTRACT OF THE DISCLOSURE       An X-ray generator and associated method are disclosed. The X-ray generator and method are provided for inspection of objects which are conveyed into an inspection station which includes an X-ray device and image processing device.  The X-ray device directs high-energy, short-pulse X-rays toward an object as the object moves into a desired position.  This X-ray radiation is received by a video camera and the resulting image is then digitized and transmitted to an image processing device which analyzes the information and determines whether of not the object conforms to a predetermined standard threshold.  One aspect of the apparatus includes a rejection device which will remove objects which do not pass inspection thresholds.

Title: Detection of electrode/patient motion and fast restore limits
Inventor: SJOQUIST STEVEN E
IPC: A61N1/36
Filed: 1992-12-17
Abstract: DETECTION OF ELECTRODE/PATIENT MOTION        AND FAST RESTORE LIMITS                      Abstract of the Disclosure A defibrillator/monitor (10) is disclosed employing a motion detection circuit 18 and control and processing circuit (20) that cooperatively detect motion at a patient-electrode interface. In that regard, an impedance measurement circuit (24) produces an output indicative of the impedance of the interface. This output is then processed by a number of filter elements before being analyzed by a motion detection routine (52). The motion detection routine includes subroutines (62 and 64) that compare the impedance against distinct upper and lower limits and then monitor the time at which the signal is above and below the limits. Basically, motion is indicated if the signal undergoes relatively large variations for a short time, or smaller variations for a longer time. A third motion clear subroutine (66) is used to determine when motion is no longer detected. Finally, a similar scheme (102) is employed to quickly restore the various filter elements after saturation.

Title: Optical communications system and method for transmitting information through a single optical waveguide
Inventor: BROOKS WILLIAM M
IPC: H04B10/572
Filed: 1991-12-19
Abstract: An optical communication system for communicating information.  The system includes a source of continuous wave laser light (30) and one or more acoustic beams (51) which are frequency or amplitude modulated by data. The laser light beam and the acoustic beams are input to an acousto-optical modulator (50) for producing an undiffracted laser light beam and one or more diffracted laser light beams (52). The diffracted laser light beams are frequency shifted from the undiffracted laser light beam and contain the data to be transmitted. The diffracted and undiffracted beams are combined (60), and transmitted over an optical fiber (16) for demodulation at a distant location by a receiver. The receiver includes a photodiode (70) which heterodynes the diffracted and undiffracted beams and produces signals having the frequencies of the acoustic beams. Tuning circuitry (74) separates the signals and demodulators (80) reconstruct the data transmitted. By using two such communication systems with a single optical fiber and by allocating the available bandwidth, simultaneous, bidirectional multi-channel communications are achieved.

Title: Switching methods for satellite communication system
Inventor: PATTERSON DAVID P
IPC: H04L12/56
Filed: 1992-11-06
Abstract: The Switching Methods for a Satellite Communication System overcome the limitations encountered by conventional packet switching using virtual circuits. The present invention utilizes a ''datagram'' approach that routes every packet (22) conveyed by the system independently at every node in the network. The packets (22) are directed along an optimized pathway through the network by a fast packet switch (38) that directs traffic based on instructions from an adaptive routing processor (14) that continuously runs an adaptive routing algorithm (16). This adaptive routing processor (14) works together with an input packet processor (28) and a routing cache memory (20) to monitor the rapidly changing topology of each satellite (S) in the constellation and the distribution of traffic among its nodes and links. The input packet processor (28) functions like a gatekeeper or guide that extracts the destination node address (32) from each packet (22) and uses it to access routing information stored in the routing cache memory (20).

Abstract: A water turbine comprises a turbine chamber, an inlet port and an outlet port opening into the chamber, and two or more rotors arranged within the chamber with their axes of rotation parallel so as to be rotatable in the water flow passing between the inlet port and the outlet port. Each of the rotors has two or more substantially equiangularly distributed lobes and the arrangement is such that the rotors rotate in opposite directions with their lobes in mesh with one another under the action of water impinging on the lobes of the rotors. Such a turbine can be constructed to operate efficiently with a low head of water, and is additionally of simple construction and therefore inexpensive to produce.
