A system for communicating content streams (i.e. voice, video, data) between a content server connected to a power-line communications network and a remote electronic device having ultra-wide band connectivity with an interface module. The interface module is a power-line communication / ultra-wide band (PLC / UWB) module preferably connected to a conventional power outlet upon the power-line network. The interface module converts the power-line signals from the server to ultra-wide band signals which are broadcast for reception by the wireless electronic device. Return communications with the server from the wireless electronic device are also preferably supported. The power-line communication and / or ultra-wide band signal can also be encrypted for improved security. The content server and interface module are preferably configured to communicate content streams only within the portions of the bandwidth allocated by a bus master, which may comprise a content server with programming for controlling bandwidth use on the physical power-line communications network.

The present invention provides a system and method for real-time communication signaling between HTML5 endpoints and the IMS Core of a telecommunication network. The system includes a WebRTC Session Controller (WSC) that terminates Web communications with the client-side, parses, and normalizes the Web communications into an internal protocol suitable for communication with telecommunications network systems. The client-side controller provides a JavaScript API which encapsulates the signaling aspect of a communication session of the HTML5 application, including gathering media description, establishing signaling channels, and exchanging media descriptions with the WSC, populating the relevant WebRTC objects, managing the call after it has been established. The JavaScript API, which is more flexible than widgets that provide rigid capabilities, thereby simplifies development and implementation of real-time communication Web applications, enabling the developers to concentrate on the business logic implementation and innovate on user interface designs.

The present invention provides a surgical footswitch that includes a base, a pedal, an encoder assembly, a wireless interface, and an internal power generator. The pedal mounts upon the base and pivots. The encoder assembly couples to the pedal. As the pedal pivots, the encoder assembly translates the mechanical signal of the pedal into a control signal based on the pedals position and / or orientation. The wireless interface couples the encoder assembly to receive the control signal. The wireless interface also couples the surgical footswitch to a surgical console operable to control and direct surgical equipment. The wireless interface passes the control signal from the encoder to the surgical console, which then directs the surgical equipment based on the control signal. This wireless interface eliminates the tangle of wires or tethers, which may be a hazard in the surgical theater. The internal power generator translates footswitch movement into stored energy to eliminate potential failures of the footswitch during a procedure and overcome the need to replace batteries within the footswitch.

A multi-layered spectral purity filter improves the spectral purity of extreme ultra-violet (EUV) radiation and also collects debris emitted from a radiation source.

A volatile dispenser is provided, including a reservoir containing a quantity of volatile liquid having a viscosity of no greater than 3.9 centipoises. Each of its individual components has a vapor pressure of no less than 0.008 mm Hg. The dispenser also includes an emanator fluidly coupled to the reservoir (either directly or through a wick) that is comprised of elongated oriented bonded fibers, the fibers being impermeable to the volatile material.

An architecture and method for efficient termination of variable length keys in a PATRICIA trie is disclosed. By adding a null-labeled link, it is possible to terminate such variable length PATRICIA trie nodes, allowing to overcome the need for complex termination solutions. Specifically, a ternary PATRICIA block is introduced.

A respiratory mask (10) that comprises a mask body (12) and a harness (21) that includes a carriage (22) and a strap (24). The mask body (12) lacks a rigid insert, is non-elastomeric, and is adapted for fitting over a person's nose and mouth. The mask body (12) has a nose portion (14), a chin portion (16), first and second cheek portions (18 and 20), and an axis (32) that extends from the nose portion (14) to the chin portion (16). The mask body (12) is constructed to deform such that the first and second cheek portions (18 and 20) move towards each other about the axis (32). The carriage (22) is joined to the mask body (12), and the strap (24) is joined to the carriage (22) for supporting the mask body (12) over a person's nose and mouth. When tension is applied to the strap (24) and an opposing force acts at the nose and chin portions of the mask body, the first and second cheek portions (18, 20) exhibit movement about the axis (32) towards each other. The respirator mask is beneficial in that it is lightweight, easy to manufacture, and maintains a good fit to a person's face.

A sensor 40 that detects a chemical such as an organic vapor. The sensor 40 includes a film that has a film body 58 that includes a detection layer 48 and that is responsive to the presence of a chemical by providing a color change. The film also includes an occluding layer 54 that has a first major surface 59 and that is bound to the film body 58 but is inert to the detection layer 48 to preclude the occluding layer 54 and the chemical from causing a color change in the film body 58 in an area 42 normal to the first major surface 59 of the occluding layer 54. A sensor having this construction can provide a distinctly visible image on the sensor, which may be helpful in evaluating the remaining life of a filter cartridge.

Disclosed are HSV-1 amplicons that supply all necessary helper functions required for rAAV packaging and methods for their use. These HSV-1 amplicons have been shown to be capable of rescuing and replicating all forms of rAAV genomes including rAAV genomes introduced into cells by infection of rAAV virions, rAAV genomes transfected into cells on plasmids or proviral rAAV genomes integrated into cellular chromosomal DNA. Also provided are methods for preparing high-titer rAAV vector compositions suitable for gene therapy and the delivery of exogenous polynucleotides to selected host cells.

The boat control system is a propulsion system for controlling the direction of passage of a vessel underway at low speeds. Six thruster nozzles are installed around the hull so that, used individually or in combination, the boat can be maneuvered forward, backward, laterally or turned on its axis. Each impeller is driven by a water-cooled reversible DC electric motor, which allows the thruster apparatus to operate for long periods. In some embodiments, the motors are installed concentrically within their respective thruster ducts, with water flow through the ducts cooling the motors during operation. The system is controlled by a joystick located at the operator's station of the boat.

A Direct Write method of forming components on a substrate by deposition of ink by thermally curing the ink in situ, which method overcomes the need for curing by placing the substrate in an oven. The curing is performed in an exemplary embodiment using an induction coil (6) through which an oscillating current is passed. The coil (6) is placed above the region in which Direct Write ink has been deposited. The oscillating current induces eddy currents in the ink to cause heating of the ink and thus fix the ink by curing, sintering etc.

A convertible media and document storage system uses elements of common pallet rack framing and is convertible between open slot and container storage. The container storage includes pilasters hanging from horizontal beam elements of the framing, and vertically spaced apart pairs of adjustable wireform racks engage the pilasters and provide horizontal ledges for supporting containers of various sizes. The use of hanging pilasters minimizes strength and material requirements. The open slot storage includes tall vertical drawers riding on overhead rails attachable to the same horizontal beam elements and individually horizontally drawn for access to the stored material such as data tape and disk media. The storage system optimizes utilization of space and allows large facilities to reconfigure storage between open slot and container storage when demands change.
