A pneumatic shuttle valve for a ventilator is disclosed. The pneumatic shuttle valve selectively connects one of two inlet openings to an outlet opening. The shuttle valve has a plug that is forced by gas pressure entering the second inlet opening, to move to and seal against a first sealing surface, thereby forming a passageway between the second inlet opening and the outlet opening. The plug is forced by gas entering the first inlet opening, to move to and seal against a second sealing surface, thereby forming a passageway between the first inlet opening and the outlet opening.

A vacuum cleaner with a cyclone module assembly comprises a cyclone separation chamber for separating dust and debris from air, a dirt cup for collecting dust and debris that is separated from the air in the cyclone separation chamber, and a vortex stabilizer. The vortex stabilizer can be pivotally mounted to the cyclone separation chamber to allow access to the cyclone separation chamber when the dirt cup is removed from the cyclone module assembly.

An electrical connector for providing a watertight electrical connection between a flat, single or multi-traced, rigid and/or flexible printed circuit and a separate electronics unit. The electrical connector is comprised of a plug having one or more keyhole-shaped slots which serve to mechanically secure the connection between the one or more traces of the circuit and one or more fixed pins on the body of the separate electronics unit. The plug is placed over the one or more pins such that the pins are inserted up through the wider portion of the slots and in a push or pull action, the pins are slid into the narrower portion of the slot such that the pins are locked into place. The conductive traces are then secured into contact with the electrical contacts of the separate electronics device.

A system and method to prevent the improper installation of the inlet fittings for a ventilation system is disclosed. The ventilator has two inlet openings configured to accept two different inlet fittings (also called inlet fixtures). The inlet openings are different such that each inlet opening will only accept its corresponding inlet fitting. The difference between the two inlet openings can be a difference in size, shape, the inclusion of a key feature, or a combination of the above.

A ventilator system is disclosed. The ventilator has an inlet fixture configured to connect to an oxygen source and an inlet fixture configured to connect to a compressed air source. Both inlet fixtures are placed on the side of the ventilator system allowing easy access for a user to connect the two gas sources to the ventilator. The ventilator system also uses an oxygen filter and a compressed gas filter. The filter elements used in the two filters must be replaced periodically. Both filters are located on the bottom of the ventilator system and are exposed for easy access to the filter elements. A drain on one of the filter elements may use a self-sealing connector.

An integrated regulator mount for a ventilator is disclosed. The ventilator has the regulator mount built into a manifold. The regulator mount is formed into the manifold on two opposite faces. One face is configured to mount the valve seat for the regulator. The valve spring assembly is held against the valve seat by a valve spring retaining plug mounted in the manifold. The regulator case and diaphragm assembly mount on the opposite face of the manifold.

A data storage system includes controller nodes and a storage component. The controller nodes couple the storage component to a host. The storage component includes a controller and sleds with disk drives. The host and the storage component form an arbitrated loop. When the arbitrated loop is down, the controller removes the storage component from the arbitrated loop so the controller, the sleds, and the disk drives form an internal loop. When the internal loop is also down, the controller tests each of the sleds individually and marks those that are not responding properly. If a sled is responding properly the controller tests each of the drives in that sled individually and marks those that are not responding properly. The controller adds back into the internal loop the sleds and the drives that are not marked as bad, and then the storage component back into the arbitrated loop.

One embodiment of the present invention is a structure useful for testing circuits that includes: (a) a flexible substrate having contactors on a first side and pads on a second side; (b) a rigid substrate having vias aligned with the pads on the second side of the flexible substrate; (c) an adhesive layer comprised of a compliant adhesive material having vias aligned with the pads on the second side of the flexible substrate; the adhesive layer being affixed to the flexible substrate and the rigid substrate; (d) a card; (e) electrical connectors that are retained in the vias of the rigid substrate and the adhesive layer, which electrical connectors have first and second retractable ends, wherein the first retractable ends contact pads on the substrate, and the second retractable ends contact pads on the card; and (f) a clamp that is adapted to fit over the substrate and the adhesive layer, the clamp having an opening to provide access to the contactors, wherein the clamp is connected to the card.
