A comprehensive, wireless multimedia surveillance and monitoring system provides a combination of megapixel digital camera capability with full motion video surveillance with a network, including network components and appliances such as wiring, workstations, and servers with the option of geographical distribution with various wide area carriers. The full service, multi-media surveillance system is capable of a wide range of monitoring techniques utilizing digital network architecture and is adapted for transmitting event data, video and / or image monitoring information, audio signals and other sensor and detector data over significant distances using digital data transmission over a LAN, wireless LAN, Intranet or Internet for automatic assessment and response including dispatch of response personnel. Both wired and wireless appliance and sensor systems may be employed. GPS dispatching is used to locate and alert personnel as well as to indicate the location of an event. Automatic mapping and dispatch permits rapid response. The wireless LAN connectivity permits local distribution of audio, video and image data over a relatively high bandwidth without requirement of a license and without relying on a common carrier and the fees associated therewith. The surveillance system may be interfaced with a WAN (wide area Network) or the Internet for providing a worldwide, low cost surveillance system with virtually unlimited geographic application. Centralized monitoring stations have access to all of the surveillance data from various remote locations via the Internet or the WAN. A server provides a centralized location for data collection, alarm detection and processing, access control, dispatch processing, logging functions and other specialized functions. The server may be inserted virtually anywhere in the Intranet / Internet network. The topology of the network will be established by the geographic situation of the installation. Appropriate firewalls may be set up as desired. The server based system permits a security provider to have access to the appliance and sensor and surveillance data or to configure or reconfigure the system for any station on the network.

A system and a method for creating a stable and reproducible interface of an optical sensor system for measuring blood glucose levels in biological tissue include a dual wedge prism sensor attached to a disposable optic that comprises a focusing lens and an optical window. The disposable optic adheres to the skin to allow a patient to take multiple readings or scans at the same location. The disposable optic includes a Petzval surface placed flush against the skin to maintain the focal point of the optical beam on the surface of the skin. Additionally, the integrity of the sensor signal is maximized by varying the rotation rates of the dual wedge prisms over time in relation to the depth scan rate of the sensor. Optimally, a medium may be injected between the disposable and the skin to match the respective refractive indices and optimize the signal collection of the sensor.

A system and method for delivering increased speed, security, and intelligence to wireline and wireless systems. The present invention includes a new generation Fast Circuit Switch (packet / circuit) Communication processors and platform which enables a new Internet Exchange Networking Processor Architecture at the edge and core of every communication system, for next generation Web Operating System or Environment (WOE) to operate on with emphasis of a non-local processor or networking processor with remote web computing capabilities.

A data access, replication or communications system is distributed across a terminal-side executable running on a terminal and a server-side executable. Together the terminal-side executable and the server-side executable form a client to a larger server and collaborate by sending messages using a message queuing system over a network. The larger server can be, for example, a mail server. Splitting the client into a terminal-side executable and a server-side executable allows a terminal, such as mobile device with limited processing capacity, power, and connectivity, to enjoy the functionality of full-featured client access to a server environment using minimum resources on the mobile device by distributing some of the functionality normally associated with the client onto the server side executable, which is not so resource constrained.

In embodiments of the present disclosure improved capabilities are described for increasing the bandwidth in a large area broadband LTE wireless network, where regional optimization servers are incorporated near the wireless network in association with the public data network gateway, thus reducing the time-latency for applications being run from a mobile cellular device. Further, by associating additional optimization servers at base stations, application functionality may be optionally transferred from the regional optimization server to the local base station optimization server in instances where a number of mobile cellular devices are requesting the same data via their access through the same cell, and in other instances, to the effect that back haul network bandwidth utilization is reduced or eliminated.

Ultrasound applicators able to both image a treatment site and administer ultrasound therapy include an array of transducer elements that can be focused. In several embodiments, an electronically phased array is used for controlling the focal point of an ultrasound beam. The ultrasound beam produced thereby can also be electronically steered. To reduce the quality factor or Q of the array when the array is used for imaging, an electronic switch is selectively closed, placing a resistance in parallel with each of the array elements. A flexible array is employed in several embodiments and is selectively bent or flexed to vary its radius of curvature and thus control the focal point and / or a direction of focus of the array. In another embodiment, each of the transducer elements comprising the array are individually mechanically pivotable to steer the ultrasonic beam produced by the transducer elements.

A method includes polling a first plurality of one-hop gateway serves for available bandwidth and available number of CPU cycles for each respective one-hop gateway server, receiving a request to provide data to a media sink in a desired format, determining a bandwidth requirement and an estimated number of CPU cycles required for servicing the media sink, determining a second plurality of one-hop gateway servers having an available bandwidth greater or equal to the bandwidth requirement and an available number of CPU cycles greater or equal to the estimated number of CPU cycles, determining a one-hop gateway server from the second plurality of one-hop gateway servers appropriate for providing the data to the media sink and configured to receive data in a second format, and transcoding the data from a first format to the second format. An example gateway server and a computer program product usable therewith are also provided.

The disclosed embodiments disclose techniques for restoring an archived file in a distributed filesystem. Two or more cloud controllers collectively manage distributed filesystem data that is stored in one or more cloud storage systems; the cloud controllers ensure data consistency for the stored data, and each cloud controller caches portions of the distributed filesystem. Furthermore, cloud controllers may archive infrequently-accessed files in an archival cloud storage system. During operation, a cloud controller receives a request from a client system to access an archived file, and restores this archived file from the archival cloud storage system.

A high performance imaging system for diffuse optical tomography is disclosed. A dense grid utilizing sources, e.g., light emitting diodes (“LEDs”), that achieve high performance at high speed with a high dynamic range and low inter-channel crosstalk are complemented by a system of discrete, isolated receivers, e.g., avalanche photodiodes (“APDs”). The source channels have dedicated reconfigurable encoding control signals, and the detector channels have reconfigurable decoding, allowing maximum flexibility and optimal mixtures of frequency and time encoding and decoding. Each detector channel is analyzed by dedicated, isolated, high-bandwidth receiver circuitry so that no channel gain switching is necessary. The resulting improvements to DOT system performance, e.g., increased dynamic range and decreased crosstalk, enable higher density imaging arrays and provide significantly enhanced DOT image quality. A processor can be utilized to provide sophisticated three dimensional modeling as well as noise reduction.
