Patent CA-2259963-A1 (CA)
Inventor: AKHAVAN-TAFTI HASHEM
IPC: G01N33/535
Filed: 1997-11-07
Abstract: Cette invention se rapporte à des procédés pour détecter des analytes ou des espèces cibles au moyen de deux partenaires de liaison spécifique à marquage enzymatique, dans lesquels les deux enzymes fonctionnent en association pour produire un signal chimioluminescent détectable. Ces procédés utilisent un partenaire de liaison spécifique marqué avec une enzyme hydrolytique, afin de produire un activateur phénolique à proximité étroite d'un second partenaire de liaison spécifique marqué par peroxidase. Ce procédé est utile pour détecter et quantifier avec une spécificité accrue diverses molécules biologiques, y compris des antigènes et des anticorps, par la technique de l'immunodosage, des protéines par analyse Western blot, et des ADN par analyse Southern blot, et des ARN par l'analyse Northern blot. Ce procédé peut également servir à détecter les mutations d'ADN et les segments de gènes juxtaposés dans des translocations chromosomiques et plus particulièrement à identifier sans ambiguïté les génotypes d'hétérozygotes en un seul test.

Title: System for delivery of drugs by transport
Inventor: KAMEN DEAN L
IPC: A61K9/70
Filed: 1997-09-15
Abstract: A method and apparatus for introducing a fluid agent into body tissue by causing transport of the fluid agent into the dermis of the subject. The outer surface of the skin of the subject is drawn against a plurality of micropenetrators such that microfissures are cloven into the epidermis and fluid may be introduced for diffusion or suction within the dermis. Suction creates a pressure gradient within the dermis to cause fluid take-up by the dermal tissue. The micropenetrators are produced by punching an array of protrusions in the surface of a thin sheet creating sharp edges for penetrating the epidermis.

Title: System and method for selection and retrieval of diverse types of video data on a computer network
Inventor: BROWNELL LONNIE J
IPC: G06F17/30
Filed: 1998-03-13
Abstract: A system and method for the selection and retrieval of various types of video data from distributed delivery sites calls for the deployment of "Smart Mirror" sites throughout a network, each of which maintains a copy of certain data managed by the system. Each "Smart Mirror" site maintains copies of the data in several alternative file formats. Every user is assigned to a specific delivery site based on an analysis of network performance with respect to each of the available delivery sites. Generalized network performance data is collected and stored to facilitate the selection of additional delivery sites and to ensure the preservation of improved performance in comparison to traditional networks. The appropriate file format is automatically selected based on the capabilities of a user terminal making a request for data.

Title: Roll master
Inventor: MARSHALL ANTHONY FREDERICK
IPC: A01K83/06
Filed: 1999-12-13
Abstract: In a device for holding and presenting baitfish, it is known to have a plastic head holder which slides over the head of the baitfish. The baitfish is secured into the device using a toothpick or a plastic pin, which is pushed sideways through the device and the bait's head. There is a hole near the front of the plastic device where the fishing line enters and another hole at the rear of the plastic head where the line exits and hooks are attached. Hooks are set into the baitfish and pulled tight producing a curve which then causes the rolling action which attracts and catches fish. In this invention, a maleable wire is attached to a plastic head holder such that it extends horizontally in a manner which allows the end of the wire to be inserted into the baitfish and guided lengthwise through its entirety with the head of the baitfish sliding finally into the plastic head holder. This wire within the baitfish allows the fisherman to manipulate the baitfish's body, obtaining a number of different rolling patterns. This invention may have varying lengths of wires depending upon the desired size and type of baitfish.

Patent CA-2310305-A1 (CA)
Title: Distortion compensation in optically amplified lightwave communication systems
Inventor: SRIVASTAVA ATUL KUMAR
IPC: H04B10/17
Filed: 2000-05-30
Abstract: Distortion and crosstalk that occurs when operating optical amplifiers in saturation is substantially reduced by passively compensating for gain variations caused by changes in input power to the optical amplifiers. More specifically, in an optical communication system having one or more optical amplifiers, a "reservoir" optical channel is supplied in addition to the other traffic-carrying optical channels. The wavelength of the reservoir channel is selected such that the power level of the reservoir channel varies in response to changes in power levels of the traffic-carrying channels. Because gain variations are typically highest around the gain peak region in an optical amplifier's gain bandwidth, the reservoir channel in one exemplary embodiment is assigned a wavelength around the gain peak region. As such, the reservoir channel can absorb or otherwise receive most of the distortion and crosstalk while the traffic-carrying channels located away from the gain peak region will experience less distortion and crosstalk.  Importantly, this passive compensation scheme can be used in an amplified system which is operating in the presence of nonlinear distortions caused by gain variations, such as inter-modal distortion and saturation induced crosstalk.
