Patent CA-2286018-A1 (CA)
Title: High impact communication and control system
Inventor: CARSTENSEN KENNETH J
IPC: E21B47/18
Filed: 1998-04-07
Abstract: A system and method in accordance with the invention communicate remotely with remotely controllable downhole tools in a well bore at a drilling installation. At the surface, high energy pressure impulses directed into the tubing or the annulus, or both, being at a level to propagate through an interface between very different impedances zones, such as an upper level gas zone and a lower level of mobile fluid media extending down into the desired downhole location. The pressure impulses, provided by directionally gating along the longitudinal confining path a pressure impulse initially having sharp leading and trailing edges, reach the downhole location as physical perturbations forming a discernible pattern that can be detected by one or more energy responsive transducers. With combinations of these signals, one of a number of separate control devices can be remotely actuated. The system avoids the need for physical or electrical connections and concurrently greatly reduces the likelihood of accidental operation.

IPC: B43L13/10
Filed: 1999-11-24
Abstract: A tile marking apparatus for marking the contour of an object to be circumvented by a tile directly onto the tile including a base portion and a contour following rod is described. The contour following rod is so mounted to the base portion as to be laterally and longitudinally movable with respect to the base portion. The rod includes a distal end provided with a contour following tip and a proximate end provided with a pen. The distance separating the tip and the pen correspond to the dimensions of the side of a tile to be marked, and to that effect, the rod is preferably telescopically mounted in order to be adjustable. The tile to be marked is positioned above the tiles previously installed adjacent to the intended position and the base portion is positioned above the tile to be marked. The contour following tip may then follow the contour of the object to cause the pen to reproduce the contour directly onto the tile. A method to use the apparatus is also disclosed.

Title: 3 dimensional imaging of hard structure without the use of ionizing radiation
Inventor: PERELGUT MICHAEL D
IPC: A61B8/08
Filed: 2000-01-26
Abstract: A diagnostic process for generating, recognizing, and remotely examining layers of tooth using prod reflection data from physical waves to produce high-resolution quantitatively measurable 3D images. The present invention examines interior portions of tooth structure. The layers can be considered to be common impedance objects, which are present in a uniform background. Acquire data sets for the area of interest and then acquire a 3 dimensional reflection data volume. This data is then subjected to diagnostic 3 dimensional processing to produce a vertical and horizontal high-resolution matrix. In a similar manner this method of imaging tooth structure can be used to measure other hard structures in the body (i.e. bone) or outside the body (i.e. Cement, concrete, rock etc).

Title: Time-slot interchanger that controls both time-slot access and signal processing features
Inventor: PETTY NORMAN W
IPC: H04Q11/04
Filed: 2000-03-07
Abstract: A time-slot interchanger (TSI 100) is used to control both time-slot access and distribution of signals to physical or virtual signal-processing circuits (106-116). The TSI includes a control table (200) with an entry (202) for each time slot, that specifies the source (204, 205) and destination (230, 231) of signals received during the corresponding time-slot interval and the processing (208-228) of those signals. The TSI is coupled to the signal processing circuits, and sends the received signals to the signal processing circuits for processing along with control signals to effect the processing specified by the corresponding control-table entries. For conferencing, the TSI sends all signals for each conference in sequence to the conferencing circuit (108) before starting and sending any signals for any other conference, thereby allowing a single conference accumulator to support any number of conferences of any size.

Title: Apparatus for electro-surgical tissue removal
Inventor: ABELE JOHN E
IPC: A61B18/12
Filed: 1998-09-25
Abstract: An electro-surgical device (11) for performing tissue resection and cauterization includes an elongated body, a pair of arms extending from a distal end of the elongated body, and an electrode (12) in communication with the pair of arms. The elongated body is adapted to be coupled to a source of energy at a proximal end. The electrode (12) has a first region coated with an insulative coating and a second region for focusing energy emission. The coating can be a diamond-like carbon coating or other coating exhibiting resistance to cracking at high temperatures and high voltages. The coating can be deposited on a base section of a loop electrode (14) while the end sections remain free of the coating. Alternatively, the coating can be unevenly deposited on the electrode. In other embodiments, the electrode can comprise a rollerball and the insulative coating can be deposited on selected or random portions of the rollerball. The insulative coating prevents energy loss to fluid and tissue during the operation, thus allowing resection and cauterization to be efficiently performed.

Patent CA-2307076-A1 (CA)
Inventor: FALCO ROBERT N
IPC: H04R1/10
Filed: 2000-04-28
Abstract: The present invention presents a selective nonlinear attenuating earplug (10). The earplug (IO) is tunable by the wearer and permits the wearer to select the performance of the earplug (10). The earplug (10) of the present invention can function either in a selective attenuation mode or a maximum attenuation mode. The selective capability of the earplug permits a wearer to select the degree of desired sound attenuation depending upon the particular environment surrounding the wearer. In the selective attenuation mode, sound attenuation is low for a specific range of intensities and increases for sounds with intensity above those in the specified range. Selective attenuation is especially effective for the loudest noises. The advantage of a selective attenuation mode is especially realized when the wearer wishes to receive an intelligible speech transmission while being situated in a noisy environment while still protecting the wearer from dangerous noises.

Patent CA-2312939-A1 (CA)
Title: Fabric hydroenhancement method and equipment for improved efficiency
Inventor: LAWRENCE JACKSON
IPC: D04H1/46
Filed: 1998-12-04
Abstract: Improvements in hydroenhancement efficiency are obtained by operating a manifold in relative movement to fabric transported under the manifold so as to deliver a low energy to the fabric per pass in multiple passes on the fabric. This results in greater enhancement efficiency and reduction in wasted energy, and also improves fabric coverage and reduces fabric shrinkage. The low energy-per-pass, multiple-pass approach can be implemented with improved hydroenhancing equipment of reduced equipment size and cost which simulate multiple passes on the fabric. In one embodiment, a jigging hydroenhancing equipment transports the fabric (12) back and forth under a stationary manifold (60a, 60b) between a pair of unwind/windup reels (64, 66) to simulate multiple passes on the fabric. Other embodiments employ a manifold or manifold system that is reciprocated (50), oscillated (50a, 50b; 70a, 70b), or rotated (82) to simulate multiple passes on the fabric. Another variation for improving hydroenhancement includes angling the manifold (30a, 30b) at a diagonal to the fabric.

Title: Binders with a foldable pocket assembly
Inventor: WIEN THOMAS M
IPC: B42F13/00
Filed: 2000-07-26
Abstract: The present invention is generally directed to a foldable pocket assembly that is coupled to a cover of a binder along one of the edges of the pocket assembly.  The pocket assembly has a first portion and a second portion divided by a fold line. The second portion is foldable along the fold line and adapted to releasably hold in the folded position adjacent to the first portion. Each portions may have a pocket or adapted to hold pencils and pens. As such, the present invention makes more efficient use of the space left between the cover and the papers held in the three ring binder to increase the carrying capacity of the binder. Furthermore, some pockets are not visible so that sensitive items may be more securely held in the hidden pockets.
