Patent CA-2116538-C (CA)
Inventor: JAEGER NICOLAS AUGUST FLEMING
IPC: G02F1/01
Filed: 1992-09-01
Granted: 2002-03-26
Abstract: A slow-wave electrode structure suitable for use in integrated optical modulators having a pair of spaced substantially parallel integrated optical waveguides in a compound semi-conductor substrate (such as gallium arsenide (GaAs) or indium phosphide (InP)) is formed by a pair of substantially parallel conductor strips on the surface of the substrate each in a position for interaction with its respective adjacent of said waveguides. The conductor strips are capacitively interconnected by narrow fins each integral with one of the strips and extending between the strips whereby the conducting strips and fins may be applied as a single layer to the substrate. The narrow fins significantly increase the capacitance per unit length between the strips without an equivalent decrease in inductance per unit length along the strips such that the phase velocity of the microwave signals is reduced.

Abstract: A multi-cavity dielectric filter 30 having a single housing 32 for a plurality of resonant cavities 65. The dielectric filter 30 has a plurality of dielectric resonators 42 placed inside housing 32, instead of in individual housings, wherein the resonators 42 are spaced a quarter wave apart and are electrically isolated from one another by conductive isolation plates 44 positioned therebetween. The isolation plates 44 do not make continuous mechanical contact with the interior conducting surface of housing 32, but rather are spaced from the inner surface 77 of housing 32, thereby making assembly of the filter much simpler than if a solid RF connection had to be made. The resonators 42 are positioned inside the housing 32 between the isolation plates 44 and are supported by low loss, low dielectric constant spacers 46. End walls 59 complete the cavity formation at the termination ends 79 of housing 32. For a band reject filter, the cavities are joined by coupling loops connected to a transmission line while for a bandpass filter, apertures are placed in the isolation plates (44') so as to couple electromagnetic energy between adjacent cavities (65).

Abstract: A saturating-inductor (112) or transformer (114) is used to shape input current flowing into an alternating current (AC) to direct current (DC) power supply (100) to correct the power factor for the supply. If a saturable inductor (112) is used, it is connected to feed current into the power supply (100) and a capacitor (113) is connected across the input of the power supply. The capacitor precharges the saturable inductor to a point just short of saturation during a preliminary portion of each sinusoidal half cycle of the input AC power. For steady state operation, this is the point at which current will start to flow into the AC to DC power supply and the inductor will saturate. Since the inductance falls in accordance with the permeance curve characteristic of material used to construct the inductor, the current will continue to flow at the same or an increasing level despite the declining voltage level of the AC input power.
Patent CA-2140726-C (CA)
Title: Lancing device with automatic cocking
Inventor: PURCELL D GLENN
IPC: A61B5/15
Filed: 1995-01-20
Granted: 1995-08-04
Abstract: The present invention is a lancing device with an automatic cocking feature. The automatically cocking lancing device utilizes a firing button loaded with a firing button spring and a drive spring connecting the firing button to a plunger. As the user presses the firing button and compresses the firing button spring, the user also moves the plunger until the plunger engages a latching mechanism. The latching mechanism holds the plunger in a latched position, and, as the user continues pressing the firing button, the user compresses the drive spring connected to the plunger. Before firing, the drive spring is compressed enough such that the biasing force of the drive spring is sufficient to cause the plunger to strike and drive a lancet into the user's finger. At that point, the pressing of the firing button causes the lancing device to fire. The plunger unlatches and drives the lancet into the user's finger under the biasing force of the drive spring. At firing, the firing button spring is compressed, and, once the user releases the firing button, the firing button spring returns the plunger and the firing button to the cocked position under the biasing force of the firing button spring.

Abstract: The present invention provides a method of controlling fluid loss to a permeable formation penetrated by a wellbore.      A novel fluid loss agent is prepared by forming a crosslinked polymer gel which then is sheared to break the gel into discrete particles. A slurry then is formed of the particles by dispersing the particles in an aqueous fluid having a density similar to that of the gel particles . The slurry then is introduced into contact with the permeable formation and a filter cake of the particles is formed upon contact with the formation and loss of the slurrying fluid to the formation.      The filter cake provides further fluid loss control to the permeable formation.

Abstract: The present invention is a smart tray for an in-home audio player adapted to play pre-recorded music stored on a semiconductor music chip storage medium. Music chips are loaded into the smart tray which holds a predetermined number of chips and is inserted as part of the audio player. Each tray will have a low cost, low power microprocessor on board to handle routing and accessing of the music from an individual chip on the tray. For instance, the tray level microprocessor will be able to cue up a next song selection while a digital signal processor (DSP) within a base portion of the audio player finishes decoding the current selection. The smart tray minimizes music selection search times and allows the DSP to focus on processing the encoded music from the chips thereby minimizing housekeeping activities performed by the DSP and increasing efficiency. The smart tray allows for active music selections by the user so that the user can select a particular artist, song, music style, etc. with the touch of a button. This can be done since the music chips self-register content and music style to the smart tray upon power up. The audio player can be expanded by adding additional smart trays up to a predetermined limit.
