Abstract: A memory system includes a client device and multiple memory devices. The client device communicates an operation request pertaining to a particular data object to one memory device. Referencing a host table, the memory device identifies multiple memory devices associated with an object key of the data object. The memory device communicates the operation request to the identified memory devices to be completed. If one of the memory devices in the memory system becomes inaccessible, the memory system is capable of replacing the inaccessible memory device in the host table. Furthermore, if a new memory device is added to the memory system, the memory system is capable of modifying the host table to associate some of the possible object keys with the new memory device.

Abstract: A roll bar assembly capable of punching through a rear window on deployment comprises a deployable u-shaped roll bar fitted with a pin made of hard material. The pin may be fixed to an upper surface of the roll bar or may be housed inside the top portion of the roll bar and deployed at the appropriate moment by pyrotechnic means.

Abstract: A submersible article comprises a buoyancy body formed from polyurethane foam having a first density, which is at least partly overmolded with a protective skin of polyurethane foam having a second density higher than the first density. The lower density foam of the body gives the article buoyancy, while the higher density protective skin strengthens the article and gives impact resistance. The protective skin can be stiffened, either uniformly or locally, by the addition of glass fiber or other reinforcing material which is arranged over the buoyancy body prior to the overmolding. The article can be made by a two-stage molding process.

Abstract: A method for monitoring information in a network environment is provided that includes receiving one or more packets from a communication flow initiated by an end user. The information associated with the communication flow is then selectively communicated to a plurality of client-aware network elements.

Abstract: A gas and air mixing device receives a pressurised supply of a gas, drawing an air supply from the ambient environment and outputs a pressurised combined mixture of air and said gas. The device includes a turbine with a gases inlet and a gases outlet and a pump with an air inlet and an air outlet. A combined gases outlet receives gases from the gases outlet of the turbine and air from the air outlet of the pump. The combined gases outlet ouputs a combined flow of the gases. The turbine is configured to drive the pump.

Abstract: A gases delivery conduit for the supply of humidified medical gases as formed from an extruded plastic tube. The extruded plastic tube includes at least one heating element embedded within the wall of the tube. The heating element includes a pair of electrical conductors separated by a positive temperature coefficient material wherein the localised resistance of the material is positively related to the localised temperature.

Abstract: A pre-stretch wrapping device consisting of a base, a pre-stretch station, a vertical drive, and a rotatable load causes a pre-stretched web to become wrapped around the load under controlled tension. The pre-stretch station comprises a pair of pre-stretch rollers located on a pivotal frame, a spring which opposes the pivotal movement of the frame relative to the base, a roller motor, and a sensor located between the frame and the base. The sensor monitors relative movement of the frame from the base and a controller in response to signals from the sensor controls the operation of the roller motor.
