Abstract: A system and a method for simultaneous transmission of multiple media streams in a fixed bandwidth network are disclosed herein. The system is comprised of a central gateway media server and a plurality of client receiver units. The input media streams arrive from an external source and are then transmitted to the client receiver units in a compressed format. A state machine on the gateway media server detects if the network bandwidth is close to saturation. In one embodiment, the potential bandwidth saturation is measured by matching the time when the start of unit of media for each stream against the estimated transmission time for that unit.

Abstract: A stretcher (18) has front wheels that are powered by a motor (146). An operator actuates a lever (150) to cause the wheel to be powered. The powered wheels can be moved between a position in which they are constrained to rotate about a common axis extending between the wheels to a position in which each wheel can swivel separately.

Abstract: A system and a method for simultaneous transmission of multiple media streams in a fixed bandwidth network are disclosed herein. The system is comprised of a central gateway media server and a plurality of client receiver units. The input media streams arrive from an external source and are then transmitted to the client receiver units in a compressed format. A state machine on the gateway media server detects if the network bandwidth is close to saturation. In one embodiment, the potential bandwidth saturation is measured by matching the time when the start of unit of media for each stream against the estimated transmission time for that unit. When any one actual transmission time exceeds its estimated transmission time by a predetermined threshold value, the network is deemed to be close to saturation, or already saturated, and the state machine executes a process of selecting at least one stream as a target for lowering total bandwidth usage.

Abstract: A method and apparatus for providing accessing to applications in centralized application system includes processing that begins by having the server execute an application in response to a request and/or inputs by one of the clients to produce application data. The processing continues as the server provides an application interface for interfacing the application data for the requesting client to produce interface data. The processing continues when the server encodes the interface data to produce encoded data. The processing as the server provides the encoded data to the plurality of clients. The processing continues as the targeted client determines that it is being addressed by the encoded data. The processing continues as the targeted client decodes the encoded data to produce display data.

Abstract: A person sitting on a stretcher or a chair has their weight taken by a board 10. That weight is transferred to pistons 20 to urge those pistons 20 down into liquid containers 16 to increase the pressure. The increased pressure from the action of the pistons is passed through to a control and display device 24 to give an indication of the weight of the patient which may comprise an alarm if a predetermined weight is exceeded.
