  • Patent number: 9297071
    Abstract: A solid precursor delivery assembly generally includes a container having upper and lower portions and chambers defined within the container, including an inlet chamber, an outlet chamber, and first and second precursor chambers. The first and second precursor chambers are configured for holding precursor material within the container. Sintered frits are fixedly coupled and sealed to an interior portion of the container, and define at least part of the chambers within the container. At least one of the sintered frits is configured for retaining precursor material thereon within the first precursor chamber, and at least one of the sintered frits is configured for retaining precursor material thereon within the second precursor chamber. An inlet is coupled to the container for delivering carrier gas into the container, and an outlet is coupled to the container for use in removing vaporized precursor material and carrier gas from the container.

  • Patent number: 9286879
    Abstract: A scheme for localizing a wireless user equipment (UE) device's relative position with respect to a spatial configuration based on audio signatures received via a multi-channel audio system, e.g., an audio system of a vehicle or home entertainment system. The wireless UE device is configured to capture the audio signatures received from a head unit that are placed in an out-of-hearing band of a captured signal. The wireless UE device includes a persistent memory module having program instructions for processing the captured signal including the out-of-band signatures, which may comprise either channel-specific pseudo-random noise (PN) sequences or single-frequency tones, in order to compute time delays or power levels associated with the speaker channels. A localization module is configured to estimate the wireless UE device's relative position based on the time delays or power levels.

  • Publication number: 20160070609
    Abstract: In one embodiment, a system includes at least one processor and logic integrated with and/or executable by the processor, the logic being configured to instantiate, using an interface definition language (IDL) on a first server, a remote procedure call (RPC) function to exchange information between the first server and a second server, generate at least one stub on the first server using the RPC, and generate at least one stub on the second server using the RPC, wherein the at least one stub generated on the second server does not perform any marshalling or un-marshaling of data when endianess of the two servers is the same. Other systems, methods, and computer program products for exchanging information between servers using RPCs are described in more embodiments.

  • Publication number: 20160051841
    Abstract: A method of image-guided radiotherapy for treatment of a radio-resistant or radio-sensitive tumor. A three-dimensional visualized tumor image is obtained and the boundary of the tumor is identified. A boosted radiation dose of treatment is designated and applied to a boost region within the tumor boundary. A predetermined prescribed radiation dose is simultaneously applied with the boosted radiation dose within the tumor boundary and in a planning target volume region, which is outside of the tumor boundary. The boosted radiation dose outside of the boost region decreases at a boost dose decreasing rate such that the boosted radiation dose is equal to the predetermined prescribed radiation dose at the tumor boundary.

  • Publication number: 20150304161
    Abstract: A scheduler may run a script. The script may have a plurality of configuration commands for a network device. A first configuration command of the plurality of configuration commands may be called to begin. A script engine may determine whether a termination request has been received. The script engine may run the first configuration command when it is determined the termination request is not received. While the first configuration command is running, the script engine may receive the termination request. Instead of terminating immediately upon detection of a termination request, the first configuration command may complete.

  • Patent number: 9165547
    Abstract: A scheme for localizing a wireless user equipment (UE) device's relative position with respect to a spatial configuration based on audio signatures received via a multi-channel audio system, e.g., an audio system of a vehicle or home entertainment system. The wireless UE device is configured to capture the audio signatures masked within a background audio signal received from a head unit. The wireless UE device includes a persistent memory module having program instructions for processing the background audio signal including the masked signatures, which may comprise either channel-specific pseudo-random noise (PN) sequences or single-frequency tones, in order to compute time delays or power levels associated with the speaker channels. A localization module is configured to estimate the wireless UE device's relative position based on the time delays or power levels.
