Title: Flow responsive time delay pump motor cut-off logic
Inventor: RASMUSON GORDON L
IPC: E21B47/00
Filed: 1998-09-11
Abstract: An automatically controlled fluid flow responsive method for achieving de-energization of an electric motor operatively connected with a downhole pump being connected to a production tubing string of a well when flow from the downhole pump becomes abnormally low. A selective electronic cut-off signal is programmed, representing a selected minimum acceptable rate of discharge flow from the downhole pump. A  flow transducer provides an electronic flow related signal to the control circuitry, representing actual pump discharge flow. The control circuitry is also programmed with a selected electronically controlled time delay period which is initiated when the flow related signal becomes less than the selective cut-off signal. When the flow related signal remains less than the cut-off signal for the duration of the time delay period the control circuitry interrupts the electrical power supply to the pump motor. The time delay motor cut-off control logic is provided with an adjustable "set flow" logic and an adjustable "cut-off delay"  logic which establish parameters of allowable minimum pump discharge flow and the time period that the pump will be allowed to operate below a preset minimum allowable flow rate. A  flow transducer is provided to monitor the pump discharge and continuously provides flow related signals which are received by the control logic. When the preset "minimum flow" and "time period" settings are met the control logic will provide a control signal to de-energize the electrical power circuit of the pump motor, thus shutting down the pump or to shift the pump to a lower operating speed. The pump motor cut-off logic incorporates a start-up delay which maintains the pump cut-off logic in a deactivated state for a period of time which is selected to permit the well production system to reach its operational characteristics.

Title: Orthogonal signal multiplexing system
Inventor: BLEIWEISS SCOTT J
IPC: G06F12/16
Filed: 1997-02-25
Abstract: A dynamically upgradeable disk array chassis (10), a method for dynamically upgrading a data storage system, diplexed computer communications and a diplexer (50) wherein the diplexer (50) and the diplexed communications may be used in the dynamically upgradeable disk array chassis (10). The dynamically upgradeable disk array chassis (10) includes a serial bus (22) having a first bus for passing data in one direction and a second bus (24) for passing data in the opposite direction. A shunt (40) connects the first (22) and second (24) buses in a normal state. The shunt (40) has a switched state in which each of the first and second buses is coupled to a separate output from the chassis. The chassis (10) includes an environmental monitor (30) connected to a communication path (42). Upon connecting a new disk array chassis to an active disk array chassis, the environmental monitor (30) communicates through the communication path (42) before switching the shunt (40) to connect the serial bus with the serial bus of the new disk array chassis. The disk array chassis (10) may include a diplexer (50) for connecting the communication path (42) to the separate outputs of the shunt (40) and for combining the communicaton path signals with the serial path signals in one direction and for separating these signals in the other direction. The diplexer (50) may include an adder for adding the signals from the communication path with those on the serial path and a subtractor for subtracting signals of one path from the other. The environmental monitor path communications and the serial bus communications can take place over a single twinax cable (18). One signal is differentially coupled onto a first pair of conductors. A second signal is common mode coupled onto the first pair of conductors. In the opposite direction on the twinax cable (18), different signals are also differentially coupled and common mode coupled to the return pair of conductors.

Patent CA-2254311-A1 (CA)
Title: Telepad
Inventor: SIEGLE ULRICH
IPC: H04M1/17
Filed: 1998-12-04
Abstract: Using a telephone which has been previously handled by an infected person makes one susceptible to catching contagious viruses. The microphone area of the telephone receiver is an ideal breeding ground for microorganisms. When one is speaking into the microphone of the telephone receiver a transfer of microorganisms takes place. Any person subsequently using the telephone will be breathing in the viruses from the microphone area.      This is a very unhealthy situation as the telephone has been proven to be a common spreader of microorganisms.      To repel an attack of such invaders is to stick a Telepad on to the microphone area of the telephone receiver thus reducing your chances of contracting a contagious virus.

Abstract: An optical switch includes an optical router portion for distributing multi-wavelength optical signals received at input ports of the switch, an optical combiner portion for supplying multi-wavelength signals at the output ports of the switch, and optical fibers for interconnecting the optical router portion and optical combiner portion. Selected ones of the interconnecting optical fibers include wavelength-selective elements, such as fiber gratings, which are capable of transmitting or reflecting individual channels within the multi-wavelength optical signal so that a selected channel of a particular wavelength can be routed from any of the input ports to any of the output ports of the switch. In one exemplary embodiment, the optical router portion includes a plurality of input optical couplers, wherein each input optical coupler is associated with a corresponding input port of the optical switch. Similarly, the optical combiner portion includes a plurality of output optical couplers, wherein each output optical coupler is associated with a corresponding output port of the optical switch. Each input optical coupler together with its associated fiber gratings on the interconnecting optical fibers is used for distributing the signals received via the input ports while each output optical coupler together with its associated fiber gratings is used for combining the signals to be supplied at the output ports of the switch. By controlling the transmissive and reflective operating modes of the fiber gratings, the fiber gratings can facilitate the switching of individual channels of the multi-wavelength optical signals on a wavelength by wavelength basis.
