Abstract: Methods and apparatus are described. A long term evolution-advanced (LTE-A) wireless transmit/receive unit (WTRU) includes a transceiver and a processor. The transceiver receives discontinuous reception (DRX) configuration information. The processor, in response to the received DRX information, controls the transceiver to monitor LTE-A physical downlink control channels (PDCCHs) in subframes in a first frequency band during an active time. The processor further, in response to detecting a downlink assignment in an LTE-A PDCCH in the first frequency band during the active time, wherein the downlink assignment indicates a second frequency band and assigned subcarriers within the second frequency band, to receive an LTE-A physical downlink shared channel (PDSCH) K subframes after a transmission of the downlink assignment. The second frequency band is different than the first frequency band.

Abstract: A fluid control device for hydraulic systems is provided having closure means movably positioned within a valve housing and adapted to selectively close a fluid passageway in response to a predetermined pressure level. The closure means includes a piston body slidably located in the valve housing for reciprocating movement therein and a spring adapted to bias the piston body away from a shoulder to maintain the fluid passageway open during normal operation. The piston body includes a conical nose and a plurality of flow channels (or apertures) which allow fluid to pass through the piston body during normal flow. When the fluid pressure is large, indicating a downstream break or leak in the flow line, the fluid pressure will overcome the force exerted by the spring and force the piston body against the shoulder, thereby blocking the flow pathway and stopping flow through the device.

Abstract: A fluid shutoff device for use as a safety device to cut off the water supply to a building in the event of overly high water consumption due to a leak or break in the plumbing in the building is provided with a motor that is responsive to remote actuation to rotate a three position selector valve to a desired flow setting. The selector valve is settable in a position which allows water to flow freely through the safety flow control device as if it were not there, a position which diverts water through a safety flow pathway, or a position that prevents water flow into the main water line entrance of the building, thereby allowing the invention to act as a shutoff valve. At least one optoelectronic device is included in the safety device to monitor the flow position of the selector valve by detecting the absence or presence of light reflected off a sensor drum that rotates in synchronism with the selector valve.

Abstract: A device for use as a safety device to cut off the water supply to a house or building in the event of overly high water consumption due to a leak or break in the plumbing in the house or building is disclosed which has only three moving parts and is of simple and inexpensive to manufacture construction. The safety flow control device of the present invention has a three position selector valve which selectively either allows water to flow freely through the safety flow control device as if it were not there, diverts water through a safety flow chamber, or acts as a shutoff valve by preventing the flow of water into the main water line entrance of the house or building.
