Patent CA-2296829-A1 (CA)
Inventor: PRENTICE JOHN
IPC: G05F3/26
Filed: 2000-01-25
Abstract: A low voltage MOSFET-configured current sink/source has an output node coupled to the drain of an output MOSFET, that is current mirror coupled with a diode-connected reference current MOSFET. The output MOSFET has its gate resistor-coupled to the gate of the reference current MOSFET and its drain coupled to the source a third V GS-feedback control MOSFET of a feedback circuit, that includes a further current mirror circuit. This third MOSFET has its gate electrode coupled in common with the drain-gate connection of the reference current MOSFET. The V GS-feedback control MOSFET is coupled with a further current mirror, the output of which is coupled to the gate-coupling resistor. In response to a drop in the drain-source voltage V DS of the output MOSFET so that the point that output MOSFET no longer operates in its saturation region, the V GS-feedback control MOSFET turns on, causing the flow of drain current in the feedback control MOSFET. The further current mirror circuit mirrors this drain current through the gate-coupling resistor, causing a voltage drop across it, so that the value of gate-source voltage applied to the output MOSFET is increased.

Title: Improvements in or relating to sound detection
Inventor: LANGDON ROGER MARTIN
IPC: G01S17/88
Filed: 1999-01-18
Abstract: Detection of remote acoustic signals is achieved using a pulse to pulse coherent laser beam (20) which is projected from a telescope (19) to a remote region (21) that contains acoustic signals from a nearby source (not illustrated). Light from the beam (20) is scattered in the region (21) and a resultant signal (23) collected by a telescope (24). The signal (23) and a reference (27) are applied to an interferometer (26) and the resultant interference pattern (28) applied to a photoreceiver (29).  An alternating current (30) is produced across the photoreceiver (29) which corresponds to the scattered light from the beam caused by the periodic movement of acoustic signals through a region (21). The detector (10) can be used to determine the curvature of an acoustic signal wavefront and to detect the location of a source producing the acoustic signals.

Title: High efficiency intracavity doubled laser and method
Inventor: MACKINNON NEIL
IPC: H01S3/109
Filed: 1998-09-10
Abstract: An intracavity doubled single longitudinal mode laser is disclosed which provides stable (i.e., low amplitude variation in its output beam intensity), efficient operation. An associated method is also disclosed. A lasant material (36) is positioned in the cavity for producing light at a desired fundamental wavelength and possibly other, unwanted wavelengths. Polarizing means (38) and a type I doubling material (36) are also positioned in the cavity. During operation of the laser, the polarizing means polarizes the desired fundamental wavelength as well as the unwanted wavelengths of light produced by the lasant material. The type I doubling material then produces output wavelengths at twice the frequency of any wavelengths passing therethrough. The type I  doubling material and the polarizing means are arranged such that they cooperate in a way which causes the unwanted wavelengths to be subjected to losses which result in the unwanted wavelengths being extinguished while the desired fundamental wavelength is subjected to a level of loss above a lasing threshold so that the desired fundamental wavelength lases, thereby producing the desired output wavelength. In one aspect of the invention, blue light may be produced as the output wavelength.

Filed: 1999-12-28
Abstract: A filter that has captured live bacteria is treated by an extraction reagent and a luminous reagent, an emission status of the filter is imaged by a television camera (1) comprising an optical system and an imaging means (such as CCD), the number of luminescent points is counted from image data of microorganism-derived fluorescent luminescent points via an image processor (3) and data analyzer (4), and the results are displayed on a display (5). If luminescent points exist around and adjacent to one luminescent point during the data analysis, a group of these luminescent points are counted as one point. Effects by a diffused light generated from a luminescent point with a large luminance are also removed. Accordingly, counting errors that might be encountered when a shape of a luminescent point derived from one microorganism is complicated or that might be caused by effects by a diffused light generated due to a large luminance can be minimized.

Filed: 2000-12-27
Abstract: In a valve operating system in an internal combustion engine, one of adjacent rocker arms is provided with first and second support walls with the second support wall disposed on the side of the other rocker arm, anal a roller is disposed between the first and second support walls to come into rolling contact with cams. A cylindrical roller shaft, on which the roller is rotatably supported, is provided between the first and second support walls, so that a switchover pin of an associative- operation switchover means can be slidably fitted into the roller shaft in response to the movement thereof to an associatively operating position. The roller shaft is press-fitted into at least second one of the first and second support walls, and a press-fit margin for the roller shaft press-fitted into the second support wall on the side of the other rocker arm is set smaller than a press-fit margin for the roller shaft press-fitted into the second support wall on the side of the roller. Thus, the roller shaft supporting the roller and guiding the switchover pin can be fixed easily to the rocker arm, while avoiding an increase in number of parts and an increase in number of processing steps. Moreover, during movement of the switchover pins to the associatively operating position, the deformation of an end of the roller shaft receiving the switchover pin due to the press-fitting is suppressed to a small level, thereby smoothening the press-    35  fitting of the switchover pin into the roller shaft to smoothen the associative operation of the adjacent rocker arms and the releasing of the associative operation by the switchover pin.
