Patent CA-2298483-A1 (CA)
Inventor: TRAIN RUSSELL H
IPC: G09F19/22
Filed: 2000-02-16
Abstract: The invention is a novel and improved method of illuminating and displaying stationary images, so as to create the illusion, to an observer in a state of relative motion, that the image or images being viewed are those of an optically focused, singular image or animation sequence. The invention of the novel animation display system, consists of a combination of; image re-digitization process specifications as well as design specifications for the associated, parallax light filtering system. Application of the inventions methods and design specifications, permit the invention to simulate the effect of modern day video or motion pictures. It is the application of two key processes that produces a stable image or the illusion of animation. First image frames are re-digitized or re-pixilated, in-order to counteract the blurring effects of viewing discrete images in motion, particularly when viewed at close range. Secondly, to allow an observer to view a longitudinal scan of an appropriate series of pixels in a predetermined sequence, a plurality of parallax scanning filters are used to mask the images. The scanning filters allow the viewer to apply the concepts of persistent vision and to perceive the re-formatted imagery as an optically focused, singular image or animation sequence.

Title: Sterilizer including air purging system and pressure actuated door seal
Inventor: STEWART PHILIP M
IPC: A61L2/07
Filed: 2000-03-03
Abstract: A sterilizer including a sterilization chamber for receiving articles to be sterilized and a door supported on a horizontal pivot at an access opening of the sterilizer chamber. The door includes a seal plate and a resilient seal member supported on the seal plate wherein the seal member includes an annular lip extending transversely to the plane of the seal plate. The lip extends into the sterilizer chamber wherein pressure within the chamber exerts a force biasing an opposing surface of the lip into engagement with an inner surface of the chamber. The sterilizer door is movable between a fully closed and a fully open position and includes a mechanism for holding the door in a partially open position. In the partially open position, the lip extends into contact with a surface of the sterilizer chamber to thereby form a bridge between the door and chamber and prevent condensation from dripping down away from the chamber and door. A controller is provided for controlling sterilization cycles and actuates the door to move to the partially open position at the end of a sterilization cycle. In addition, a pressure actuated lock is provided for preventing the door from opening when the chamber is pressurized. The controller further automatically controls purging of air from the sterilizer chamber during a steam generation mode of a sterilization cycle wherein the controller senses the temperature and pressure during the sterilization cycle, and in response thereto, opens a purge valve to release air when the conditions within the sterilizer deviate by a predetermined amount from preset conditions monitored by the controller.

Title: Strategy for negotiation of telecommunication resources
Inventor: PREISS BRUNO R
IPC: H04L12/911
Filed: 2000-03-10
Abstract: A telecommunication system and method provides for negotiation between participants in a desired communication to establish the communication. The desired communication is defined by a set of parameters arranged in a hierarchy of stages and values for the parameters of each higher stage are negotiated before negotiation of those in the next lower stage. When values for all parameters in all stages have been agreed, the communication is established. If one or more parameter values cannot be agreed at a stage, forensic information is provided to the participants who can retry or abandon the negotiations. In one embodiment, a failed negotiation is restarted by a participant modifying a value for a parameter in a previously agreed stage and restarting the negotiation at that stage with the new value.  Various negotiating disciplines can be employed to negotiate the stages, including a Round Robin negotiating discipline. Further, two or more participants can compete within a stage and the participant with the most favorable terms is selected for inclusion in subsequent stages while the others are removed from the negotiation.

Title: Integrated guided-tissue-regeneration barrier for root-form dental implants
Inventor: SCHAPPERT DOUGLAS ALAN
IPC: A61C8/00
Filed: 1998-12-10
Abstract: An integral guided tissue regeneration barrier for root form dental implants is herein described. The barrier is meant to facilitate osseointegration of implants placed with trans-mucosal healing elements immediately into tooth extraction sites. The barrier comprises an absorbable circumferential membrane arranged to exclude epithelial cells but not osteoblasts from the tooth extraction socket in which the implant is placed. As a result of this arrangement, the implant becomes osseointegrated into the jaw of the patient. If an increase in bone volume around the implant is required, the membrane may be supplemented by a sheet membrane of titanium mesh or foil or absorbable material such as bovine or porcine collagen or synthetic polymer. That is, both the integral guided tissue regeneration barrier and the supplementary sheet membrane are composed of materials that do not need to be removed, thereby reducing to one the number of surgeries required to progress from a dentulous site to a site with a loaded implant.

Title: Hydrologic cells for the exploitation of hydrocarbons from carbonaceous formations
Inventor: HSU KENNETH J
IPC: E21B43/24
Filed: 1999-03-11
Abstract: Fluid and/or heat are induced to flow from one natural or artificial underground aquifer (11), which extends vertically, at an incline or horizontally, across a host-rock formation to a well (12).  Alternatively, fluid and/or heat are induced to flow from a well (14) across the host-rock formation to a natural or artificial aquifer (13).  The aquifer and well constitute the polarities of a hydrologic cell, like the electrodes of a battery or electric cell. An aquifer can be formed by fracturing the host formation and by injecting proppants into the fracture. Fluid and/or heat is injected into the source of the hydrologic cell and is induced to flow across the hydrocarbon bearing host formation within the cell such that the displacement of the injected fluid or heat causes the hydrocarbon to flow into the sink of the hydrologic cell. Aquifer(s) or well(s) can serve as either the source or the sink of the hydrologic cell. At least one aquifer serves as one of the polarities of the hydrological cell.

Title: Image transmitting system for transmitting dynamic image data
Inventor: EJIRI SATORU
IPC: H04N21/2343
Filed: 2000-12-07
Abstract: An image transmitting system which maintains the same image resolution even when a line speed is set to a low speed. The image transmitting system basically comprises an image data conversion block, a quantization block, a variable-length coding block, smoothing buffers, output selectors, and a dequantization block. The image data conversion block converts input image data into a coefficient suitable for coding. The quantization block quantizes the coefficients obtained through conversion. The variable-length coding block codes the quantized coefficients. The first smoothing buffer smoothes the generated amount of data with respect to a first frame in a block, the second smoothing buffer smoothes the generated amount of data with respect to a second frame in the block, and the third smoothing buffer smoothes the generated amount of data with respect to a third frame in the block. The first output selector is used when selecting a line speed of 96 Kbps, and the second output selector is used when selecting a line speed of 128 Kbps. The quantization block reproduces the previous frame for use in an interframe conversion.

Title: Optical transmission system including performance optimization
Inventor: AL-SALAMEH DANIEL YOUSEF
IPC: H04B10/14
Filed: 2001-02-21
Abstract: Vulnerability of an optical network to channel impairments or the like, is addressed by utilizing real-time monitoring and control of one or more prescribed optical channel impairments. The one or more impairments are compensated for by employing an optimization process in the optical network such that the optical signals from the source or sources of the impairments are controllably adjusted at any particular node in the network. In a specific embodiment of the invention, the optical signals are attenuated more or less at the source node of the associated optical channel, e.g., wavelength .lambda., in order to optimize performance of the corresponding optical channel in the network. This is realized by employing a variable optical attenuator at the .lambda. laser source of optical channel having the impairment. More specifically, in a particular embodiment of the invention, the optical signal impairment is measured at a receiving node and the source node of the associated optical channel is determined. Then, a control message is transmitted to the identified source node indicating that a variable optical attenuator associated with the corresponding optical channel light source, e.g., .lambda. laser source, is to be adjusted to insert more or less attenuation as the case may be.    This measurement and adjustment process is iterated until the corresponding optical channel yields optimum performance for the impairment being measured. In this embodiment of the invention, the control messages are transmitted in an optical supervisory channel. In another embodiment of the invention, a VOA in a remote node associated with the .lambda. laser source of the associated optical channel is first adjusted. Thereafter, if necessary, a VOA in the local node associated with the optical channel being monitored is adjusted to further optimize the prescribed metric of the optical channel being monitored. This adjustment of the local VOA is iterated until the performance of the associated channel is optimized. In still another embodiment of the invention, either a VOA in a remote node associated the .lambda. laser source of the associated optical channel adjusted or a VOA  at a local node associated with the received prescribed optical channel is adjusted or both VOAs are adjusted depending on an evaluation of the prescribed metric of the prescribed optical channel to optimize the prescribed metric of the prescribed optical channel. In yet another embodiment of the invention a VOA in a remote node associated the .lambda. laser source of the associated optical channel adjusted and a VOA at a local node associated with the received prescribed optical channel are substantially simultaneously adjusted to optimize the prescribed metric of the prescribed optical channel.
