Patent CA-2251699-A1 (CA)
Title: Real-time multispecies monitoring by laser mass spectrometry
Inventor: SYAGE JACK A
IPC: H01J49/16
Filed: 1997-04-01
Abstract: A monitor that photo-ionizes trace constituents within a quadrupole ion trap (QIT). The QIT (102) may have a valve (116) that discharges a gas specimen into a trap chamber (106) or a gas line (216) that continuously discharges a gas specimen into the QIT. The trap chamber is surrounded by a ring (104), and an extractor plate (108) that has an orifice (112). The trace molecules within the air may be ionized at the nozzle of the valve by a photo-ionizer (120). Photo-ionizing at the valve nozzle provides a relatively high density of ionized molecules. The photo-ionizer may be either a pulsed light source or a continuous wave light source. The trace molecules are preferably ionized with energy between 8.0 and 11.0 electron volts (eV). The energy is selected to ionize the trace molecules without fragmenting the trace constituents. A radio frequency or other oscillating frequency voltage potential is applied to the ring to trap the ionized trace molecules within the trap chamber. A voltage pulse is applied to the extractor plate to pull the ionized molecules out of the chamber and through the orifice. The extracted ionized molecules are then accelerated (126) to a detector (130). The monitor has a time of flight analyzer (100) to measure the mass of the trace constituents in the specimen.

Patent CA-2253760-A1 (CA)
Inventor: CHAN ERIC K Y
IPC: A61B5/0402
Filed: 1996-05-06
Abstract: Acquisition and analysis of electrocardiogram signals, to non-invasively detect and quantify presence of abnormal cardiac conduction patterns in patients at risk of heart disease. Signals from the orthogonal (X, Y, and Z) surface leads are amplified (44, 36, 48), digitized (40) and either stored for later processing or processed immediately. The incoming beats can either be R  wave triggered, aligned and ensemble averaged for patients at risk for ventricular pathologies, or P wave triggered, aligned and ensemble averaged for patients at risk for atrial pathologies. QRS onset and offset, and P wave onset and offset are calculated for ventricular and atrial post-analysis applications respectively. The windowed Fourier transform of the second derivative (acceleration) of the signal averaged ECG is calculated for regions of interest for each lead. A Spectral Change Index, calculated from the "acceleration spectrum" for each lead serves to quantify the degree of spectral fragmentation within a pre-specified bandwidth.

Abstract: the suction sleeve of a milking inflation includes three axially extending side walls connected together to form a generally triangular cross section. The side walls have a convex section which bulges slightly outwardly such that, where the inflation is installed on a teat cup shell and the side walls are in a full open position, a built-in spring effect is induced into each side wall to bias them toward the full open position and such that the biasing force of this built-in spring must be overcome before the side walls can be moved inwardly toward a closed position in response to the shell chamber being exposed to atmospheric pressure and assists movement of the side walls toward an open position in response to exposing the shell chamber to a subatmospheric pressure.

Patent CA-2271452-A1 (CA)
Inventor: LIPOWSKI JOSEPH THADDEUS
IPC: H04B1/18
Filed: 1999-05-12
Abstract: A receiver desensitization system sets the sensitivity of a receiver by injecting a desensitization signal appearing as noise onto a receive path of the receiver to adjust the noise power level relative to the power level of signals on the receive path. For example, a desensitization source provides a desensitization signal appearing as noise onto a desensitization path. An adjustable attenuator on the desensitization path adjusts the power level of the desensitization signal to provide a desired level of desensitization. The desensitization path is coupled to a receive path of a receiver, and the desensitization signal is injected into the receive path. The desensitization signal desensitizes the receiver by raising the noise power level relative to the signal power level on the receive path. The desensitization signal can be injecting into the receive path after a main amplifier on the receive path. By injecting the desensitization signal after the amplifier, the desensitization system reduces the contribution to the overall noise figure that would occur if any attenuation of the signal were to occur before the input to the amplifier. Depending on the application, the desensitization signal can be injected into the receive path at the radio frequency (RF), intermediate frequency (IF) or baseband stages of the receiver. The desensitization signal can take a variety of forms, such as broadband noise, a continuous wave signal, a modulated signal, or a digital pseudo-random noise sequence.

Abstract: The exhaust gas enters via an exhaust gas line (1) into a washing apparatus (2). In the washing apparatus (2) solid matter particles are predominantly separated. The pre-washed exhaust gas flows from the washing apparatus (2) through a droplet removing conduit (10) to a trickling filter device (11) in order to be subjected to an activated sludge treatment for the separating of gaseous contaminants. In order to reduce the point of condensation and accordingly the absolute humidity of the exhaust gas for the activated sludge treatment either fresh air is added through a feed line to the pre-washed exhaust gas or the washing water which is led in a closed circuit through the washing water line (5) of the washing apparatus (2) is cooled in a heat exchanger (26) in a cooling tower. A portion of the washing water of the washing apparatus (2) is led through a first solid matter removing apparatus (7) of which a portion of the filtrate is led to an activated sludge basin (13) located under the trickling filter device (11). A portion of the water of the activated sludge basin coming from the trickling filter device (11) is led to a second solid matter removing apparatus (17), of which a portion of the filtrate is led in a counter-move to the washing water of the washing apparatus (2).

Title: Controlling aip print uniformity by adjusting row electrode area and shape
Inventor: YOUNG MICHAEL YU-TAK
IPC: B41J2/015
Filed: 1999-05-13
Abstract: An acoustic ink print head includes an array of individual emitters. Each of the emitters have a corresponding transducer with a lower electrode, a separate layer of a piezo-electric material located on the lower electrode, and a separate upper electrode provided on the upper surface of the piezo-electric layer. The upper and lower electrodes are connected to a source of conventionally modulated RF power. A dielectric layer is deposited on top of this structure and lenses are etched into the top of the dielectric layer. The lenses focus energy generated by the transducer to a region of the upper surface of a body of liquid located above the transducer. Tree lenses concentrate sound waves from the transducers thereby disturbing the surface and causing droplets to be emitted. The print head is formed as an array of individual emitters. The upper electrodes of the individual emitter array have varying surface areas dependent upon their location within a row of electrodes and their output efficiencies. The upper electrodes are altered in order to provide a uniform end-to-end print output.

Title: Clampless universal joint and boot assembly
Inventor: LILLEY ALBERT
IPC: F16D3/84
Filed: 1999-08-13
Abstract: A universal joint such as a constant velocity (CV) joint in a drive assembly of a front wheel drive vehicle can require a boot to seal the joint from environmental contaminants found on a highway or other vehicle driving surface. Typically, such boots are attached using a clamp, however it has been found that the crimps extending from the clamp can interfere with a vehicle's ABS sensor. The present invention provides a clampless means of attaching the boot to the CV joint, by providing a continuous rib projecting from inner surface of an end of the boot, and a coincident groove on the end of the universal joint, wherein the rib has a means for cooperating with the groove to retain said rib within the groove. It is contemplated that the present invention can be used on other types of universal joint and boot assemblies.
