Abstract: Various systems and apparati as well as devices and structures are provided which may be used or incorporated into air handling systems (e.g. (air) ventilation systems and apparati) for the manipulation or control of air in a enclosure such as a building, a room of a structure such as a residence, and the like. Such air handling systems (e.g. ventilation apparati or systems) may for example include an element for the transfer of heat from warm exhaust air (taken from inside an enclosure e.g. a building) to cooler exterior fresh air (drawn into the enclosure e.g. building). The present invention further relates to air handling systems (e.g. ventilation systems and apparati) which may not only exhaust stale interior air to the outside of an enclosure but as desired or necessary also intermingle a portion of such stale air with fresh air for delivery of the intermingled air back into the enclosure (during cold or warm weather). The present invention in particular relates to air handling systems (e.g.  ventilation systems and apparati) which may exploit warm interior air as defrost air for defrosting the system during cool weather.
Patent CA-2636419-A1 (CA)
Inventor: CULLY EDWARD H
IPC: A61M29/00
Filed: 2007-01-12
Abstract: The present invention relates to a non-evertable blood filter that divides the transverse cross sectional area of a venous vessel into three annular regions or zones. The inner zone, the region immediately surrounding the longitudinal axis of the vessel, is maintained in a relatively open state with only minimal interference from the members making up the filter device so that blood flow can be maintained at a relatively normal rate. Concentrically surrounding the inner zone is the intermediate zone, to which captured emboli are directed out of the bloodstream passing primarily through the inner zone. Finally, concentrically surrounding the intermediate zone is the outer zone adjacent to the vessel wall. This is also intended to be kept free of emboli, so that emboli in the bloodstream immediately adjacent the vessel wall are directed away from the wall by the filter design and into the intermediate zone, thereby avoiding the accumulation of emboli adjacent the vessel wall that might otherwise result in stenosis. The blood filter is intended primarily for use as an inferior vena cava filter, although it can be made in a range of sizes allowing its use in blood vessels and particularly venous vessels of differing diameters. The filter is preferably removable.

Patent CA-2639457-A1 (CA)
Inventor: SHEEHAN BRIAN D
IPC: F16K31/12
Filed: 2008-09-11
Abstract: A valve is disclosed for use in a system and process for controlling vehicle loading on a multi-axle vehicle and improving maneuverability. The valve partially exhausts air from an axle air bag when the vehicle is maneuvering at slow speed, reduces the load on the axle, and thus reduces damaging forces that affect tire wear and suspension component wear. The valve is a normally open, pilot operated valve that delivers supply air pressure upon receiving a sustained air pressure input of a pilot signal. Using an inversion function, the valve then dumps the delivery pressure through a high capacity exhaust upon receiving the pressure input of a secondary control signal. The hold function of the valve traps a reduced amount of delivery air pressure by closing the exhaust valve, and the hold function is actuated at a predetermined delivery pressure to trap a volume of air in the associated air suspension system until the valve member is returned to a supply position.

IPC: B25C5/06
Filed: 2007-01-23
Abstract: A spring energized stapler includes a "high start" design wherein a striker has a rest position above the staple track. A handle is pressed to energize a power spring while the striker remains stationary. At a predetermined position of the handle, the striker is released to eject a staple. A subassembly of a cage and the power spring provides a preload to the power spring in the rest position. The subassembly is separately movable from the handle to allow a handle pressing end to move farther than the striker's distance of travel. The handle includes a movable pivot location to enable enhanced motion of the handle pressing end. Alternatively, an optional lever links the striker to the power spring to provide leverage upon the power spring. A release latch may be mounted in front of the striker to be engaged by the lever or the handle.

Title: Client/bridge and method and system for using same
Inventor: LEVY PHIL
IPC: H04W84/12
Filed: 2009-02-27
Abstract: The transmission of data is accomplished across a network having wireless and wired interfaces. Data is transferred through a wireless interface from an Access Point to a Client/Bridge and then to one of a Intelligent Electrical Device (IED) connected to the Client/Bridge through a wired connection. Data is transferred from the Access Point to the Client/Bridge through a 4 address mode wireless interface having originator, transmitter, receiver and destination address fields. The originator address uniquely identifies an IED  in the overall network, the transmitter address identifies the AP transmitting the data, the receiver address identifies the Client/Bridge receiving the data through the wireless interface while the destination address refers to one of the IEDs connected to the Client/Bridge through the wired interface. Communication can also be performed in reverse from one of the IEDs connected to the Client/Bridge through the wired interface to an IED in the overall network. The Client/Bridge determines context cache information representing the media access control numbers of each of the IEDs connected to the Client/Bridge through the wired interface and transfers this context cache information to the AP. In the event of a failure of the Client/Bridge, the context cache information stored at the AP can be transferred to the Client/Bridge using the wireless interface to facilitate recovery of the Client/Bridge.
