摘要： Various apparatus or methods are arranged to operate a tool in a wellbore, where the tool has a number of acoustic sensors. Scanning images obtained by the tool sensors along the borehole can be combined to increase the contrast of leak location with respect to background noise. A sequence of beamformed images, generated from signals captured by the tool as it moves over a range of depths of the wellbore, can be acquired. Each beamformed image may overlap at least one other beamformed image of the sequence. The beamformed images can be processed and the processed beamformed images can be combined, forming a stitched image. Additional apparatus, systems, and methods operable in providing stitched images can operate in a variety of applications.

摘要： Inverse search systems and methods operate on identifiers of content items in a corpus such as the World Wide Web. In an inverse search, the user submits a query that includes an identifier of a target content item in the corpus and receives information (metadata) about the target content item being returned to the user. Many types of metadata can be returned, including ratings or other metadata related to the target content item obtained from users, popularity data specific to the target content item, information about previously submitted forward search queries that led to the target content item being identified as a hit, and metadata extracted from the target content item.

摘要： Methods, devices and systems for sensor-based wireless communication systems using compressive sampling are provided. L User Equipments (mobile stations) transmit signals with sparsity S and their signals are compressively sensed to M samples by Z remote samplers (a distributed antenna arrangement) and the uplink channel is estimated by a central processor (the "central brain"). For a given system signal to noise ratio, retained samples M and sparsity S, we approximate the loss in sum mutual information due to imperfect knowledge of the channel. The approximation is premised on a lower bound of the mutual information which accounts for the power in the channel estimation error. Also, throughput results are given for adaptively adjusting the sparsity of multiple users' transmit signals based on channel fading.

摘要： A solid precursor delivery assembly (200) generally includes a container (202) having upper and lower portions and chambers defined within the container, including an inlet chamber (238), an outlet chamber (244), and first and second precursor chambers. (240, 242) The first and second precursor chambers are configured for holding precursor material within the container. Sintered frits (248, 250, 252) 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 (206) is coupled to the container for delivering carrier gas into the container, and an outlet (208) is coupled to the container for use in removing vaporized precursor material and carrier gas from the container.
