Abstract: A rotary connector (10) employing rolling conductive members (18). Two or more electrically isolated assemblies (15) comprising pairs of printed wiring boards (16a, 16b) or flexprint circuits (16a, 16b) are disposed in a housing (11). The printed wiring boards (16a, 16b) have conductors disposed on adjacent surfaces. The conductors are electrically connected using the rolling conductive members ( 18). An insulating spacer (21) is disposed between the metallic conductors of each of the printed wiring boards (16a, 16b) that hold them in place. The assemblies (15) are disposed adjacent each other, and a shaft (13) is secured to selected printed wiring boards (16a). The shaft (13) is rotatably secured to the housing (11) using a rotary bearing (14), and the other printed wiring boards (16b) are secured to the housing (11). The printed wiring boards (16a, 16b) have electrical wires (31)soldered thereto that permits the flow of electrical signals through the rotary connector (10), and which may be routed to electrical connectors (32) or sensors (32). A retainer (25) secures the assemblies (15) together to maintain pressure between the metallic conductors and the rolling conductive members (18). Thus, the shaft (13) is secured to one set of printed wiring boards (16a) and is rotatable relative to the housing (11) due to the bearing (14). The other printed wiring boards (16b) are fixed relative to the housing (11). The rotation of the shaft (13) therefore causes rotation of the one set of printed wiring boards (16a) relative to the other set of boards (16b), while electrical conduction is maintained between the conductors by means of the plurality of rolling conductive members (18).

Title: Device for monitoring a predetermined level of a liquid in a container
Inventor: GETMAN IGOR
IPC: G01F23/296
Filed: 1996-10-15
Granted: 2000-10-03
Abstract: For monitoring a predetermined level of a liquid in a container an ultrasonic transducer is fitted on the outer surface of the container wall at a measurement point situated at the height of the level to be monitored. The ultrasonic transducer contains a piezoelectric  element  which  generates,  when  excited  by  an alternating voltage pulse having a  given transmission  fre-quency, an ultrasonic transmission pulse which is transferred via  a  diaphragm to  the  container wall  and  which  converts ultrasonic vibrations transferred from the container wall to the ultrasonic transducer into electrical reception signals. The diaphragm comprises on the side facing the container wall protuberances which adjoin the  container wall.  Between the diaphragm and the container wall a coupling layer is arranged, the thickness of which is determined by the height of the protuberances. As a result of this the formation of a layer of air between the diaphragm and the container wall is prevented and a jump in impedance avoided so that a good acoustical coupling exists between the diapragm and the container wall.

Title: Method and apparatus for performing the register functions for a plurality of metering devices at a common node
Inventor: HARDY SAMUEL GRAHAM
IPC: H04B3/54
Filed: 1997-04-14
Granted: 2008-02-19
Abstract: A method and apparatus of the present invention includes a common node of a power line communications system for individually performing the register functions for a plurality of electrical metering devices operably connected to the node. The power line communications system includes at least one node having a plurality of registers, a respective one of which is associated with a respective electrical metering device. The electrical metering devices connected via the power lines to the node measure the power consumption of the electrical load associated therewith and transmit a signal indicative of the measured power consumption to the node and, in particular, to the respective register of the node associated with the electrical metering device. The node individually determines the power consumed by each electrical load operably connected to the node based upon the received signals. The results of such calculations are stored in the register associated with each respective electrical metering device. The stored results are also periodically transmitted to the system control center of the power line communications system. Thus, the register functions for a plurality of relatively simple electrical metering devices may be centralized at a common node.

Granted: 2003-05-20
Abstract: Video data in the form of a plurality of digitised frames, is stored on a plurality of magnetic disks. Each image frame is striped across a plurality of disks and redundant parity information, derived from the stripes, is written to an additional disk. Disk failure is detected and in response to this detection missing data is regenerated from the parity information. This allows the transfer of video data in real time to be maintained for output so that the system remains operational. While data is being read in real time, derived from regenerated data, the regenerated data is written to an operational disk, thereby reprotecting the data in the event of a subsequent failure. Frame supplied to output are labelled as being protected or unprotected and application programs may respond to this status information as considered appropriate.

Patent CA-2223316-C (CA)
Title: Electric power supply management system
Inventor: LIBERMAN ISYDOR
IPC: H02J13/00
Filed: 1997-12-03
Granted: 2008-02-12
Abstract: A communication protocol, designed for centralized power line networks, provides a solution for: automatic network mapping and adaptive routing, for automatic log-on of remote nodes and also for optimization of communication routes and control of the traffic volume. A Central Unit (CU) permanent polls all the known Remote Nodes (RN) and a polled RN replies with a message. A new Remote Node (RN), which hears any polling command from the CU, transmits a Burst Log-On Message direct to the CU. A new RN, which hears a reply of polled RN, but not the polling message itself, transmits a Burst Log-On Message, using the replying RN as a relay. There may be a route of several relays between the new RN and the CU and all of them are registered in the Log On message itself. When the CU receives the message from the new RN, it performs a log on of the RN, stores its route, and starts to poll it. This process continues all the time, enabling an addition of new nodes. RN with no communication behaves as a new one and creates a new route, when the previous is no more available. A permanent improving of the existing routes is achieved by using a special field in a message, that indicates the time the message has already traveled via the network. This field is incremented by each relay on the route, and further used by each RN, which hears the message, to improve its route to the CU. The criteria used by RN is the less the time - the better the route. For data, such as a power demand, which is a function of time and should cover all the day, the quantity of data depends on the resolution in use. The system always tries to achieve the highest possible resolution, but if the collection cycle is too long, and the transmitted data doesn't cover the required period of time, the resolution and the quantity of data are automatically reduced to provide a continuous coverage of time.
