Title: Horizontal directional drilling in wells
Inventor: SANFELICE CHRIS
IPC: E21B7/08
Filed: 2001-02-16
Abstract: A method and apparatus for horizontally drilling in wells utilizing a shoe assembly (5) at the down hole end of upset tubing (52). The shoe assembly (5) includes a fixed section (10) and a rotatable section (11) suspended below the fixed section (10). An electric motor (57) and associated batteries (13) and a gyroscope (36) carried on the rotatable section (11) enable an operator on the surface to selectively rotate and position the rotatable section (11) to any desired angular location for drilling a hole in the well casing (20). After one or more holes have been cut in the casing (20), a drill assembly (12) can be removed from the upset tubing (52) and be replaced by a high pressure blaster nozzle to bore into the formation zones. The gyroscope (36) enables the operator to accurately position the rotatable section (11) to the same locations at which the holes have been cut. The drill assembly (12) includes an electric motor (57) with an associated battery (13), flexible drive shaft (59), and a hole saw (61).

Les sondes appartenant au même ensemble sont ligaturées ensemble lorsqu'elles sont hybridées à la séquence d'acide nucléique cible et amplifiées par un ensemble d'amorces appropriées. En utilisant une quantité femtomolaire des sondes un grand nombre d'ensembles de sondes différentes peuvent être utilisées afin de déceler et, en même temps, d'évaluer quantitativement un grand nombre de séquences à haute spécificité correspondantes.
Patent CA-2403945-A1 (CA)
Inventor: CHANDRAN RAVI
IPC: G10L11/02
Filed: 2001-03-02
Abstract: In order to enhance the quality of a communication signal derived from speech and noise (20), the likelihood that the communication signals result from at least some speech is determined. A calculator calculates a first power signal representing the power of at least a portion of the communication signals estimated over a first time period and calculates a second power signal representing the power of at least a portion of the communication signals estimated over a second time period longer than the first time period. The calculator also generates a comparison signal having a value related to the likelihood that the portion of the communication signals result at least from some speech by comparing a first expression involving the first power signal with a second expression involving the second power signal. The calculator also generates a speech likelihood signal having a value representing a first likelihood that the communication signal results from at least some speech in the event that the comparison signal falls within a first range and having a second value representing a second likelihood that the communication signal results from at least some speech in the event that the comparison signal value falls within a second range. The second likelihood is different from the first likelihood.

Inventor: WANG SHEN-GE
IPC: B41J2/52
Filed: 2002-10-23
Abstract: A method of constructing a halftone screen includes selecting a frequency and screen angle of interest. A subcell having spatial vectors which satisfy the selected frequency and screen angle of interest is identified. A supercell comprising an array of the subcells is formed. An integer relationship potentially having numerous solutions exists between the supercell and the subcell. The integer relationship is solved for values of the integers and then tested against the values for the subcell spatial vectors. Although the solution may in some cases be the null set, in many cases there will be numerous solutions. Each resulting solution, if any, is then tested according to any additional constraints or tolerances specified for the particular halftone screen. If any of the resulting supercell solutions satisfies the tests, that supercell may be used to create a halftone screen.

Title: Lottery ticket bar code
Inventor: BEHM WILLIAM F
IPC: G06V30/224
Filed: 2002-10-30
Abstract: Security can be provide for lottery tickets having data printed thereon in a bar code or other machine readable media by covering only a portion of the bar code with a scratch-off material. Removing the scratch-off material, or in some cases only a portion of the scratch-off material, can permit machine validation of the lottery tickets. For bar codes having a specified level of redundancy, it is desirable to cover at least enough of the bar code so as to prevent the machine reading of ticket validation data encoded in the bar code.  Also, a lottery ticket can include a bar code printed on the ticket having both inventory and validation data along with a bar code printed on the front of the ticket including the validation data. All or part of the bar code printed on the front of the ticket can be covered by a scratch-off material.

Inventor: GAGNON GILLES
IPC: A01K61/00
Filed: 2003-03-05
Abstract: Mussels are commonly grown on ropes which have been seeded with immature molluscs. Past techniques for farming mussels have suffered from low product yields because of the low surface area of a mussel rope, and mussel detachment from the rope. Existing devices for solving these problems are cumbersome and difficult to use. The present invention solves the problems by providing a mussel farming device including a planar body with a slot in one side thereof for receiving a rope or mesh bag, an aperture at the center of the body, and a clip in the aperture for attaching the body to the rope or bag. A plurality of such devices are attached to a rope or bag at intervals along its length, thereby providing a large surface area for mussel attachment and creating stable platforms on which the mussels can mature.

Filed: 2001-12-20
Abstract: The present invention provides a method of operating a computer network with fault-tolerant nodes, comprising determining the state of a first and second link between fault-tolerant nodes and other network nodes. Data sent by the fault-tolerant node to other nodes may then be sent over a link that is selected based on the state of the first and second links. In some embodiments of the invention this takes place in an intermediate node in a network, which receives data from an originating node and forwards it to a destination node via a link selected based on the state of the first and second links. In some further embodiments of the invention, fault-tolerant nodes contain network status tables that indicate the ability of the fault tolerant node to receive data from and transmit data to other nodes via each of the links connected to the fault-tolerant nodes.

Title: Therapeutic bedding pad for hospital beds
Inventor: NEIL DORIS
IPC: A47C21/08
Filed: 2003-06-26
Abstract: A therapeutic bedding pad has a central body portion and two laterally spaced elongated side rail bumper pads is disclosed. The body portion is preferably disposed to overlay a bed frame, underneath a bedding mattress, and, when in place between the mattress and the bed frame, the body portion of the bedding pad will thus cover approximately two-thirds of a bottom length of the bed frame. The two side rail bumper pads are symmetrically disposed laterally opposite the body portion and are substantially the same length as a length of the bed frame. The bumper pads are designed to cover the top portions of the full-length side rails attached to the hospital bed in order to protect the legs and arms of bed-ridden patients from bruising, jamming and injury. In this manner, the head of the hospital bed can be raised without disturbing, or dislodging, the bedding pad, and the bedding pad does not interfere with the normal mechanisms and functions of the hospital bed.
