  • Publication number: 20140269472
    Abstract: Techniques for determining if it is safe for a mobile device to transition directly from a traffic session to a paging mode and for avoiding network re-synchronization procedures in stationary M2M devices are disclosed. It may be safe for direct transition if before-call and in-call network parameters correspond. If safe, the mobile device may transition from the traffic session directly to the paging mode to begin immediately monitoring the paging channel. In stationary M2M devices, paging information is stored before the traffic session and, once the traffic session is complete, the M2M device may be configured to receive paging messaging based on the stored paging information. The M2M device may also store system access information and confirm the validity of the information before returning to the sleep state. The stationary M2M device avoids network re-synchronization procedures. Other aspects, embodiments, and features are also claimed and described.

  • Patent number: 8695369
    Abstract: A heat pump system is provided and may include a compressor, a first heat exchanger in fluid communication with the compressor, a second heat exchanger in fluid communication with the first heat exchanger and the compressor, and a flash tank fluidly coupled to the first heat exchanger and the second heat exchanger. A first conduit may extend between the first heat exchanger and the second heat exchanger. A valve associated with the first conduit may operate in an open state to permit flow along the first conduit between the first heat exchanger and the second heat exchanger to at least partially bypass the flash tank and may operate in a closed state to prevent flow along the first conduit between the first heat exchanger and the second heat exchanger to direct flow into the flash tank.

  • Patent number: 8154656
    Abstract: A system, method, and computer readable medium for avoiding underflow of a caption buffer in a digital video encoding device. The method receives a sequence of digital video frames, and captions that correspond to the digital video frames in the sequence. The method receives first captions in a first caption carriage, and encodes the first captions, and the corresponding digital video frames, in a compressed video format. The method detects a switch from the first caption carriage to a second caption carriage, and stores second captions in the capture buffer, where each second caption is received in the second caption carriage and corresponds to one of the digital video frames in the sequence. The method examines the capture buffer and the second captions to determine whether underflow of the capture buffer is present or absent. When underflow is absent, the method encodes the second captions, and the corresponding digital video frames, in the compressed video format.
