Abstract: A system is provided with an ultrasonic flow meter. The ultrasonic flow meter includes a first ultrasonic transducer disposed about a fluid flow path, and a pressure balancing system configured to pressure balance the first ultrasonic transducer relative to a fluid flow along the fluid flow path.

Abstract: A system is provided with a pressure balancing system configured to protect a flow meter. The pressure balancing system includes a housing configured to surround a fluid conduit to define a fluid chamber around the fluid conduit. The fluid chamber is configured to house the flow meter. The pressure balancing system is configured to at least substantially balance fluid pressure internal and external to the fluid conduit via the fluid chamber.

Abstract: A medical balloon may be configured by at least partially inflating the medical balloon and forming at least one primary wing in the balloon. The primary wing extends from a central portion of the balloon. The primary wing may be manipulated to form a T-shaped wing therefrom. The balloon may then be deflated and the T-shaped wings wrapped around the balloon.

Abstract: The present invention is directed to methods, processes, and systems for roll coating portions of a workpiece as well as to workpieces that have themselves been roll coated in accord with the invention. Under these methods and processes of the invention, one of a roller and/or the workpiece may be moved longitudinally to apply coating to a target surface of a workpiece. In some embodiments, a plurality of rollers may be used and supported by arms. Still further, in accord with the embodiments of the present invention, a dispensing member may be provided to fluidly connect the roller with a reservoir. In still other embodiments, the workpiece may be an implantable medical device and the coating may include a therapeutic.

Abstract: A laser diode optical transmitter and a method of operating the optical transmitter utilize a transistor to quickly enable and disable a laser diode by selectively shorting the laser diode. In an embodiment, the transistor is separated from the laser diode by an inductor. The inductor provides a high impedance between the transistor and the laser diode to at least reduce the effect of a parasitic capacitance associated with the transistor when the laser diode is driven to generate optical signals of different power levels. The use of the transistor and the inductor (i) reduces the amount of leakage light generated by the laser diode when in a disabled state, (ii) shortens the enable and disable times of the optical transmitter, and (iii) allows the laser diode to be modulated at a high rate of speed.

Abstract: A planar waveguide (1) comprises a guiding layer (4) with densified cores (4, 5) for propagation of radiation. The cores (4, 5) are formed by selectively exposing the guiding layer (4) to UV at 222 nm with an intensity of 75 mW/cm?2 at the surface. The guiding layer material comprises components in the methacrylate functional group. There is no need for use of photo-initiator additives in the guiding layer material.

Abstract: A biolistic device for accelerating a carrier gas bearing particles is provided. The device comprises an elongate body (36) with a cylindrical channel (40) extending therethrough, wherein a first end of the channel is adapted to receive gas for acceleration and a second end of the channel is adapted to direct gas to a target. A less dispersive output beam is produced which increases the depth and penetration of the beam for a given gas pressure and provides transfection of cells over a greater depth. The elongate body (60) comprises an accelerating section (80, 82), and an output section (84) the channel (64) extending through both the accelerating section and the output section, wherein the output section has a plurality of apertures extending at an angle from an inner wall of the output section to an outer wall of the output section. These apertures (88) reduce gas turbulence within the output section and result in a laminar flow of carrier gas from the output orifice.

Abstract: A speech recognition system front end interface to provide a subscriber voice control over many voice mail functions. The speech recognition system converts spoken instructions into DTMF instructions for voice mail systems while allowing prompts form the voice mail system and DTMF tones from the subscriber to pass through without any interference by the speech recognition system. To accomplish these pass through functions, the speech recognition system sets up what is know as a hairpin connection between the subscriber, the speech recognition system and the voice mail system.

Abstract: A system and method of positioning a head of a subject to be photographed by a single camera uses a mirror and at least one collimated light beam. The single camera is positioned so that there is a selected specific location in space within a field of view of the camera at which the head or eye of the subject is desired to be positioned. A light source directs a collimated light beam or light sheet so that the light beam or light sheet intersects a line running from the mirror through the selected specific location in space and can be seen by an eye at the selected specific location in space that is looking at the mirror. The user is told to position his head across from the mirror and move his head until he sees the collimated light beam or light sheet and his eye in the mirror. When the subject is so positioned the single camera can take an image of the eye from which the subject can be identified. If desired a second mirror can be used in place of the light source.
