Patent CA-2573416-A1 (CA)
Title: Ventilation device for dehumidification
Inventor: LESTAGE MARC
IPC: B29C49/48
Filed: 2007-01-09
Abstract: The present invention relates to a ventilation device and the method of use thereof for dehumidification of residential attached or detached garages, sheds, greenhouses, RVs, motorhomes and other similar structures. This device and method uses an extraction ventilator to dry out the structure's environment, and reduce the interior humidity using a motorized fan to expel moisture latent air out of the structure. The fan continuously runs at minimal speeds to continuously exhaust interior air and ventilate the structure, thereby controlling the garage environment, while eliminating backdrafts, and preventing animals, snow and rain from entering the structure.  The device uses a dehumidistat control to activate the fan to maximum ventilation capacity when the humidity reaches the set point, exhausting ambient air and extracting excess humidity from the structure. Once the humidity drops below the set point, the dehumidistat deactivates and returns the ventilator to minimum speed operator.
Patent CA-2576423-A1 (CA)
Inventor: MACKOOL RICHARD J
IPC: A61F9/007
Filed: 2005-03-08
Abstract: A flexible sheath (32, 34) is attached to an end of a rigid extension tube (20,14). The other end of the rigid extension tube is connected with a surgical handpiece. Two flexible sheaths may be used - one as a barrier against contamination of aspiration tubing (18) and the other as a barrier against contamination of irrigation tubing (12). This is effected by securing two rigid extension tubes between the surgical handpiece and an associated one of the aspiration and irrigation tubings. Each flexible sheath is collapsible and expandable so they may be expanded from a collapsed condition over the associated aspiration or irrigation tubings and secured in the expanded condition. The aspiration and/or irrigation tubings are connected to a cassette of a surgical pack.

Patent CA-2587591-A1 (CA)
Inventor: HARRISON MATTHEW DAMIEN
IPC: D06F37/22
Filed: 2005-11-07
Abstract: The invention provides an automatic balancing device (50; 150; 150a; 250; 350) for counterbalancing an out-of-balance mass present in a body (12) which is rotatable about an axis (18; 118; 118a; 218; 318), the automatic balancing device (50; 150; 150a, 250; 350) comprising a plurality of counterbalancing masses (60, 70; 160, 170, 190; 160a, 170a; 264, 274; 374), each of which is movable in a circular path about the axis (18, 118, 118a, 218, 318) so as to generate a balancing force (FB; FB1, Fb1; FB2). In use, the balancing forces (FB; FB1, Fb1; FB2) combine to produce a resultant balancing force (FR) which is variable between a minimum value and a maximum value. The automatic balancing device (50; 150; 150a; 250; 350) is configured so that, at a first speed of rotation of the body (12) about the axis (18; 118; 118a; 218; 318), the movement of at least one of the counterbalancing masses (60, 70; 160, 170;  160a, 170a; 264, 274; 374) is restrained so that a substantially constant, non-zero resultant balancing force (FR) is produced, the said resultant balancing force (FR) being freely movable about the axis (18; 118; 118a; 218; 318). At a second speed of rotation of the body (12) about the axis (18; 118; 118a; 218;  318), the counterbalancing masses (60, 70; 160, 170, 190; 160a, 170a; 264, 274; 374) are free to adopt a position in which the out-of-balance mass is counterbalanced. The device (50; 150; 150a; 250; 350) allows at least partial counterbalancing of the out-of-balance mass at speeds below the critical speed of the system in which it is used and this reduces the maximum excursion of the body (12) through the critical speeds.

A displaceable support member (30), having a second pair of feet (32), is engaged with the guide formation such that the displaceable support member is slidably displaceable along the guide formation and is automatically frictionally engageable with the guide formation in response to pivoting of the displaceable support member about a pivot axis which is transverse to the guide formation, to anchor the displaceable support member frictionally against sliding displacement relative to the guide formation. A pair of springs (48) is provided to urge the support member downwardly. The support member is located in channel shaped spokes (20) to inhibit swiveling thereof on the guide formation. The guide formation is preferably a pin received in a bushed guiding passage (36) in the support member.

IPC: A61K9/72
Filed: 2006-05-18
Abstract: A method for fabricating a micro-electro-mechanical device (such as a cMUT) is disclosed. The method combines a substrate, a middle spring layer and a top plate using wafer bonding technology or sacrificial technology. A cavity is formed on either the top of the substrate or the bottom of the middle spring layer. A connector is formed on either the top of the middle spring layer or the bottom of the top plate. Upon joining the three layers, the connector defines a transducing space between the top plate and the middle spring layer.  The connector is horizontally distanced from the sidewall to define a cantilever anchored at the sidewall. The cantilever and the cavity allow a vertical displacement of the connector, which transports the top wafer in a piston-like motion to change the transducing space. Multiple device elements can be made on the same substrate.

Abstract: An augmented, adaptive algorithm utilizing model predictive control (MPC) is developed for closed-loop glucose control in type 1 diabetes. A linear empirical input-output subject model is used with an MPC algorithm to regula te blood glucose online, where the subject model is recursively adapted, and th e control signal for delivery of insulin and a counter-regulatory agent such a s glucagon is based solely on online glucose concentration measurements. The M PC signal is synthesized by optimizing an augmented objective function that minimizes local insulin accumulation in the subcutaneous depot and control signal aggressiveness, while simultaneously regulating glucose concentration to a preset reference set point. The mathematical formulation governing the subcutaneous accumulation of administered insulin is derived based on nomina l temporal values pertaining to the pharmacokinetics (timecourse of activity) of insulin in human, in terms of its absorption rate, peak absorption time, and overall time of action.
