Patent CA-2428587-A1 (CA)
Inventor: BAILEY TIMOTHY J
IPC: G01D5/353
Filed: 2001-11-29
Abstract: An apparatus and method for interrogating fiber optic sensors non-intrusively sensing fluid flow within a pipe includes a two beam interferometer which comprises an optics circuit for generating a series of discrete light pulses that are directed at sensors positioned between pairs of low reflectivity fiber Bragg gratings. The successive light pulses are split into first light pulses and second light pulses and the second light pulses are delayed a known time period relative to the first pulses. The first and second light pulses are combined onto a single optical fiber and directed through the low reflectivity gratings and the sensor positioned between the gratings.  Reflected pulses from the series of pulses impinge on a photoreceiver and interrogator wherein the phase shift between the reflected first light pulses from the second grating and the reflected second light pulses from the first grating for each sensor are determined. Phase shifts from successive pulses for each sensor are compared and a change in a measured parameter of the fluid is determined.

IPC: G02F1/295
Filed: 2003-10-14
Abstract: The apparatus and the method for modifying two sub-sets of properties of optical signals independently of each other, the two sub-sets preferably being optical port number and wavelength. The apparatus redistributes an input optical signal carrying many wavelengths between two or more output ports, the sub-signals at different wavelengths being routed arbitrarily and independently from each other. The apparatus is constructed out of inexpensive elements having translational symmetry and thus re-directing beams of light only in one plane. Further, the device can use either MEMS array or electro-optical steering array as optical switching means. The electro-optical steering array can include thin electro-optical film in a gradient electric field or be based on a stack of birefringent beam deflectors.

Abstract: The invention is used to employ a known method in quilt making. The said method requires a grid of prescribed measurements to be drawn on the fabric being used for the quilt that is being constructed. The invention is a flat rectangular template made of rigid material, such as acrylic. It has holes of approximately 1/16" in diameter drilled through in prescribed locations. The location for each hole is where the horizontal and vertical lines of the grid to be drawn will intersect. The template is placed flat on the said fabric and the user places the tip of a writing implement, such as a pencil, through each said hole, therefore marking the fabric with a series of dots. The resulting markings are then used as guidelines for the user to draw the vertical and horizontal lines required to form the prescribed grid of specific measurements.

Title: System for measuring material properties from a moving construction vehicle
Inventor: SCOTESE MICHAEL J
IPC: G01N33/42
Filed: 2002-09-19
Abstract: A system is for sensing a property of a material mat from a construction vehicle. The system includes a sensor for sensing the material property and a positioning mechanism connected with the vehicle and with the sensor. The mechanism displaces the sensor between first and second positions with respe ct to the vehicle as the vehicle displaces with respect to the material mat. Th e first sensor position is spaced a substantial distance above the mat upper surface. The second sensor position is located proximal to or on the mat surface such that the sensor is able to sense the material property in the second position. A controller operates the mechanism to sequentially displac e the sensor from the first to second positions, permit the sensor to remain disposed at the second position for a period of time, and displace the senso r from the second to first positions after the period of time.

Title: Tertiary filter septic system and method
Inventor: KERNS CURT
IPC: B01D24/20
Filed: 2004-09-17
Abstract: This application relates to an apparatus and method for treating effluent. The effluent may be derived, for example, from an upstream secondary treatment plant. The apparatus employs a plenum positionable within a fluid-impervious container. The plenum includes a fluid filter portion containing a hydrophilic material, such as peat, capable of transporting effluent by capillary action and a fluid collection portion for receiving effluent from the upstream effluent source. The apparatus also includes a fluid wicking conduit containing hydrophilic material for wicking effluent from the fluid collection portion. The fluid wicking conduit may be configured so that any appreciable amount of effluent introduced into the apparatus will be wicked even if the amount is substantially less than the fluid holding capacity of the fluid collection portion of the plenum. This enables the apparatus to operate substantially continuously and passively so long as some effluent is resident in the plenum. At the same time, the fluid holding capacity of the fluid collection portion can be sized to accommodate periodic surges in effluent flow. The apparatus may further include a dispersal mound of soil and vascular aquatic plants covering or adjacent to the plenum.  The invention functions as a vegetative tertiary filter.
