Patent CA-2367690-A1 (CA)
Title: Advanced ship autopilot system
Inventor: TUER KEVIN
IPC: G05D1/02
Filed: 2000-04-20
Abstract: A navigation controller and method for performing navigation control are provided. According to the method, a time varying prediction model is determined based on a predictor having a model component and a correlation processor component. The time varying linear prediction model is then used to formulate a predictive controller or to update the controller in use. The controller is then used to control navigation. Because of the correlation processor, the predictor is better adapted to compensate for shortcomings inthe model thus making the automated navigation control superior. In use, the method controls vessel navigation in any of a number of predefined modes such as cruising and turning modes. Moreover, through the selection of the operational scenario, the controller can be made to adapt to differing control objectives - for example tight tracking or increased operational efficiency of the vessel.

Patent CA-2370567-A1 (CA)
Inventor: KELLY FRANK
IPC: H04B7/185
Filed: 2001-04-12
Abstract: A system for managing return channel bandwidth in a two-way satellite communication network is disclosed. A plurality of transceivers (109) are configured to transmit backlog information over a return channel via a satellite (107). The backlog information specifies an amount of queued traffic for the respective transceivers (109). A hub (113) is configured to receive the backlog information and to allocate a predetermined amount of return channel bandwidth to each of the plurality of transceivers (109). The hub (113) determines whether additional return channel bandwidth is available to accommodate a remaining backlog such that a bandwidth allocation amount is set to a level associated with one of the plurality of transceivers (109) having the largest backlog. The hub (113) selectively identifies a transceiver (109) among the plurality of transceivers (109) having a next largest backlog based upon the determined available return channel bandwidth. The hub (113) selectively adjusts the bandwidth allocation amount to a level associated with the transceiver (109) with the next largest backlog. The hub (113) allocates the additional return channel bandwidth to the plurality of transceivers (109) based upon the adjusted bandwidth allocation amount if the adjusted bandwidth allocation amount reduces at least a portion of the backlog of the plurality of transceivers (109).

Abstract: A totally implantable cochlear prosthesis is presented. Said prosthesis is designed to function for hours or days without any external components. An externally-activated subcutaneous pressure switch enables the user to adjust  the perceived volume by pressing against the skin with a finger. A similar second pressure switch provides a safety "off/on" feature. A pliable bridge connecting two hermetically sealed housing sections, and corrugated conducto r lines, provide for future dimensional changes due to head growth. A titanium  encapsulated microphone is positioned underneath the skin in the posterior wall of the external auditory canal. A modiolus-hugging electrode array is inserted into one of the cochlea scala. Periodic charging of the implanted battery (contained within one of the housing sections) is required, such charging accomplished via an external mechanically held head-mounted device containing an external coil, said external coil inductively coupling electrical power to an implanted receiving coil. The external and implanted coils can also be used as a communication link to program the implanted electronics.

Title: Vascular filter system with encapsulated filter
Inventor: BOUCHER DON
IPC: A61F2/01
Filed: 2002-09-26
Abstract: A vascular filter system with encapsulated filter comprising a guidewire, a tip attached near the distal end of the guidewire, a filter attached near the proximal end of the tip, and actuating means for causing the filter to move between a smaller first diameter for insertion into the lumen of a vessel, and a second larger diameter for expanding to substantially equal the diameter of the lumen and to be placed in generally sealing relationship with the lumen. The actuating means comprises a catheter and a capsule attached near the distal end of the catheter. The capsule/tip combination protects the filter during insertion, and facilitates pushing and tracking the system through the vasculature. The design of the capsule and catheter increases column strength and reduces profile, thereby enhancing flexibility of the system in tortuous anatomy, and minimizing deployment forces.
