Patent CA-2756625-A1 (CA)
Inventor: NODA WAYNE A
IPC: A61M1/36
Filed: 1999-04-16
Abstract: A catheter is adapted to exchange heat with a body fluid, such as blood, flowing in a body conduit, such as a blood vessel. The catheter includes a shaft with a heat exchange region disposed at its distal end. This region may include hollow fibers which are adapted to receive a remotely cooled heat exchange fluid preferably flowing in a direction counter to that of the body fluid. The hollow fibers enhance the surface area of contact, as well as the mixing of both the heat exchange fluid and the body fluid. The catheter can be positioned to produce hypothermia in a selective area of the body or alternatively positioned to systemically cool the entire body system.

Title: A feed shaft for feeding particulate material to a mill
Inventor: PETERSEN LUIS
IPC: B02C17/18
Filed: 2010-03-24
Abstract: A description is given of an inclined feed shaft  (1) for feeding particulate material to a mill (2). The feed shaft (1) is peculiar in that it is configured for rotation about its longitudinal axis. It is hereby obtained that any incipient formation of coatings on the wall of the shaft will continuously be cleaned off and dislodged from the wall by the larger descending material particles in the feed material so that the feed shaft will be of a self-cleaning type. This is due to the fact that during the rotation of the shaft (1) the entire circumference of the shaft (1) will intermittently be located at the bottom of the cross-sectional profile of the shaft (1), and thereby be cleaned off by the descending material. As a result, coatings continuously being formed during the rotation of the shaft on those parts of the shaft wall not located at the bottom will continuously be cleaned off when these parts pass the bottom of the cross-sectional profile of the shaft (1).

Title: A method for database driven channel quality estimation in a cognitive radio network
Inventor: GURNEY DAVID P
IPC: H04W52/36
Filed: 2010-06-22
Abstract: A method of determining operating parameters for a secondary system transmitter is described. The transmitter characteristics, including location and operating frequency band, are provided to a geo-location database. The database determines the maximum allowable transmission power that meets various specifications for different channels and conveys the power and channel(s) to the transmitter. The database estimates channel incumbent signal strengths based on the transmitter location and primary and higher-priority secondary incumbent systems, estimates the splatter levels, determines whether adjacent and co-channel interference protection ratios are met, and adjusts the allowable power level accordingly. The database also estimates aggregate co- and adjacent channel primary and secondary incumbent system interference levels at the transmitter location and predicts channel quality for each allowable channel. The estimated levels are updated using measurements of actual levels at the transmitter location. The database dynamically allocates channels using the secondary system priorities.

Title: Systems and methods for seasoning meat
Inventor: BOWSMAN CLOYD D
IPC: A23L13/70
Filed: 2010-11-03
Abstract: The systems and methods described herein relate to automatically seasoning meat. In particular, the systems include a seasoning dispenser positioned over a moving conveyor. The conveyor is coupled to a partially perforated drum having agitator structures. The rotatable drum is coupled with a seasoning collector and a return conveyor, which in turn is coupled back to the seasoning dispenser. During operation, the seasoning dispenser dispenses seasoning into the cavities of meat that are disposed along the conveyor. The seasoning-filled meat falls into the rotatable drum and tumbles about while striking the agitator structures and the walls of the drum, thereby distributing the seasoning across interior and exterior surfaces of the meat. Excess seasoning is collected through the perforations in the drum by the seasoning collector and returned to the seasoning dispenser by the return conveyor for re-use.
