Patent CA-2054361-C (CA)
Inventor: SAGEY WILLIAM E
IPC: H04W88/08
Filed: 1991-10-28
Granted: 1995-02-07
Abstract: A spread spectrum processing system (10) that employs wide bandwidth spread spectrum radio transmissions overlaid over the existing cellular voice signals to simul-taneously provide additional cellular services without causing objectionable interference to current users of the cellular voice channels. The spread spectrum radio transmis-sions also support a large number of low rate digital messages. Both vehicle location and massaging functions are obtained without sacrificing any of the existing voice channel capacity. The cell site processor (40) is designed to share the existing cellular frequencies, real estate, antenna towers, antennas (31), and low noise amplifiers (32) used in the cell site radio frequency receiver chain. The only additional cell site equip-ment is the spread spectrum signal processor (3240 The processing system provides a means for achieving vehicle location accuracies that are improved by greater than two orders of magnitude over that which is possible by the current transmissions in that band. It provides a means of achieving transmit power control of the vehicle transmit-ter (11, 12) to combat the extremely large variation (dynamic range) of radio signal path loss to the receiving sites. It also provides a means of excising at the receiver the ex-cessively strong conventional voice cellular signals that are not under power control which ordinarily might interfere with the successful reception of the new broadband signals.

Title: Gain stabilized fiber amplifier
Inventor: ZIRNGIBL MARTIN
IPC: H01S3/13
Filed: 1991-11-29
Granted: 1994-07-26
Abstract: GAIN STABILIZED FIBER AMPLIFIER Abstract In this invention an optical fiber doped with a rare earth element and coupled to be pumped with a laser is coupled to an optical feedback loop. The feedback loop couples the output signal of the fiber amplifier to the input of the fiber amplifier. A narrow bandwidth filter coupled to the feedback loop allows a selected wavelength of the amplified spontaneous emission to pass from the output of the fiber amplifier to the input of the fiber amplifier. The feedback signal has a wavelength which is different from that of the pump signal and the wavelengths of the signals to be amplified. In operation, when bursts of optical signals from at least two discrete word or frequency division multiplexed channels are amplified in the fiber amplifier, the undesired fluctuations of gain of the output signals normally due to transient saturation of the erbium-doped filter amplifier are substantially eliminated.
Patent CA-2057317-C (CA)
Title: Liquid level measurement system
Inventor: MARSH NORMAN F
IPC: G01F23/16
Filed: 1991-12-09
Granted: 1996-05-14
Abstract: A system for measuring level of liquid material in a containment vessel that includes a hollow conduit composed of a first conduit section having an upper end coupled to a pressure sensor and a lower end disposed within the vessel.  A second conduit section is coupled to the lower end of the first conduit section and extends downwardly therefrom at least to a minimum material measurement level within the vessel.  The second conduit section has a vertical height coordinated with the maximum desired material measurement level within the vessel such that pressure of air captured within the first conduit section at such maximum material level prevents entry of the liquid material into the first conduit section.  The cross sectional area of air flow within the second conduit section is at least ten times, and preferably at least sixteen times, greater than the cross sectional area to air flow within the first conduit section.  Thus, the volume of air captured within the air column formed by the first and second conduit sections is minimized, thereby minimizing the effects of temperature-induced fluctuations of column air pressure.          On the other hand, liquid level within the air column remains at all times within the conduit section of larger diameter, thereby reducing the likelihood of clogging of the small-diameter conduit section due to sediments or the like carried by the liquid.
Patent CA-2057419-C (CA)
Title: Inhalation actuated dispensing apparatus
Inventor: BLASNIK WILLIAM
IPC: A61M13/00
Filed: 1991-12-11
Granted: 1996-06-04
Abstract: Movement of the cover relative to the housing spring loads and latches a piston carrier in the armed position. Inhalation causes a passageway door to open, releasing the carrier latch to permit the carrier to be moved toward the canister by the spring.  The piston moves with the carrier, due to a fluid connection therebetween, applying a compression force on the spring loaded canister valve stem and causing it to dispense the inhalant through an opening in the piston which functions as a nozzle.  After the inhalant is dispensed, the carrier fluid vents permitting the spring of the canister valve stem to move the piston relative to the carrier, and thus release the force applied to the valve stem by the piston.  The sensitivity of the toggle linkage between the door and the carrier latch is adjustable.  The linkage can be manually tripped for testing purposes.

Filed: 1990-10-25
Granted: 2002-02-05
Abstract: An in vitro method is provided herein for detecting the response of intact animal cells to an extra-cellular, exogenous cell activator substance, the activator substance being a substance which when in contact with the intact cells, activates an intracellular enzyme. The method includes contacting the cells in vitro in the presence of a substrate for the activated enzyme with the activator substance immobilised onto a solid support. The consequent activity of the activated enzyme in the presence of the enzyme substrate is then detected. Such contact takes place in one or more wells of a microtiter plate.  The well or wells of the microtiter plate, in which the contact takes place between the intact cells, the immobilised activator and the enzyme substrate has or have (each of them) a vertical side wall height of 1 to 2 mm. The method is carried out such that the reaction of the internal diameter of the well (in mm.) to the volume of the sample (in µ1.) is at least 0.1:1, and the ratio of the vertical height of the well to the vertical height (depth) of the sample in the well is in the range 1.1: 1 to 5:1.

Inventor: MIDLAND RICHARD W
IPC: H01J9/42
Filed: 1992-09-08
Granted: 2002-04-02
Abstract: An optical interrogation system has camera arrays useful for determining the locations of a plurality of apertures on a flat tension shadow mask and fiducial marks on a screened front panel of a CRT.

Title: Electronic thermostat having correction for internally generated heat from load switching
Inventor: ADAMS JOHN THOMAS
IPC: G05D23/19
Filed: 1993-03-24
Granted: 2000-11-07
Abstract: The apparatus controlling operation of a digital thermostat (13) mounted in an enclosure (15) corrects the internally measured temperature for heat generated within the thermostat enclosure by the switching element (33) controlling operation of the load, typically a HVAC unit.      The actual ambient temperature is derived by subtracting from the internal temperature a correction value which follows the fraction of total time the switching element (33) conducts power for the HVAC unit (duty cycle). The duty cycle is preferably multiplied by a scale factor and the difference between the ambient temperature as currently calculated and the internal temperature to form the correction value.

Granted: 1998-02-24
Abstract: Controllable polarisation transformer comprising a passive mode converter (4), a controllable phase shifter (5) and a controllable Mach-Zehnder interferometer (7). The mode converter (4) converts the first signal component of one polarisation (TE or TM) of a light signal entering via an input (1) into a signal component of the other polarisation without affecting the second signal component of the other polarisation (TM or TE), the conversion taking place to another order of the guided mode. Phase control by means of the phase shifter (5) controls the intensity distribution of the light signal over the two branches (8, 9) of the interferometer (7). Optical wavelength control in the interferometer (7) controls the phase with which the signals through the branches come together in the output (2).
