Laparoscopic direct vision dissecting port

A laparoscopic direct vision dissecting port for providing safe entry into a body cavity, as well as being operative to serve as a standard laparoscopic port for use in laparoscopic surgery. The device comprises an elongate laparoscopic port within which a laparoscope may be positioned. The distal-most end of the tip is transparent in nature and operatively transitional between a closed configuration and an open, operative configuration, the latter of which causing tissue to be selectively dissected in a layer-by-layer fashion while under the direct vision of the laparoscope disposed therein. The port may further optionally assume an anchor configuration once positioned within the patient to enable the same to remain securely in position during the laparoscopic surgical procedure.

NaY-type molecular sieves and preparation method thereof

The invention discloses microcrystal NaY-type molecular sieves and a preparation method thereof. In the microcrystal NaY-type molecular sieves, the molar ratio of SiO2 to Al2O3 is 4.0 to 6.0, and the average particle size is 100 to 700 nanometers. The microcrystal NaY-type molecular sieves are prepared by a method combining low-temperature synthesis directing agent, low-temperature synthesis gel and two-stage variable-temperature dynamic crystallization. The NaY-type molecular sieves have a relative crystallinity of over 80 percent after being roasted in the air at 600 DEG C for 3 hours or after undergoing hydrothermal treatment with vapor at 650 DEG C for 1 hour, as well as high thermostability and hydrothermal stability.

III-nitride light-emitting device with increased light generating capability

InactiveUS6844571B2Excellent current spreadingLow series resistanceStatic indicating devicesSolid-state devicesPeak valueElectricity
The present invention is an inverted III-nitride light-emitting device (LED) with enhanced total light generating capability. A large area device has an n-electrode that interposes the p-electrode metallization to provide low series resistance. The p-electrode metallization is opaque, highly reflective, and provides excellent current spreading. The p-electrode at the peak emission wavelength of the LED active region absorbs less than 25% of incident light per pass. A submount may be used to provide electrical and thermal connection between the LED die and the package. The submount material may be Si to provide electronic functionality such as voltage-compliance limiting operation. The entire device, including the LED-submount interface, is designed for low thermal resistance to allow for high current density operation. Finally, the device may include a high-refractive-index (n>1.8) superstrate.

Integrated illumination assembly for symbology reader

This provides a plurality of novel features that can be applied variously to a reader. In one embodiment, the light pipe is constructed from durable polycarbonate for increased shock resistance and can define a rectangular cross section. The chamfered end of the light pipe is textured or frosted to further diffuse refracted light passing through the end so as to present a more even effect. The conical / tapered diffuser within the light pipe is illuminated by a reflector with a white textured surface that reflects a plurality of rearward-directed illumination sources back into the diffuser. The reflector can define a predetermined cross section that directs further light into the forwardmost, remote regions of the diffuser to generate a better spread of light and alleviate spotting effects. The textured surface on the chamfered light pipe end can be employed to better project indicator light. The illumination sources are arranged in a ring at the inner end of the pipe, and can be multi-colored sources that respond to the controller to project and appropriate color and / or blink in an appropriate pattern to indicate various conditions, such as read success or failure. The controller is adapted to provide indications between image acquisitions. The controller can operate individual portions of the ring so that only corresponding portions of the light pipe perimeter are illuminated in a particular color (quadrants, for example) at a given time. Different quadrants may be simultaneously illuminated in different colors in one example

High alcohol content foaming compositions with silicone-based surfactants

This invention relates to a “high lower alcohol content” (>40% v / v of a C1-4 alcohol) liquid composition able to be dispensed as a stable foam with the use of non-propellant foam dispensing devices from non-pressurized containers. The liquid compositions comprise a C1-4 alcohol, (>40% v / v), a silicone-based surfactant of at least 0.001% by weight for foaming to prepare a foamable composition, 0-10% w / w of additional minor components added to obtain the desired performance (a foamable composition), and the balance being purified water. The compositions may include emulsifier-emollients and mosturizers, secondary surfactants, foam stabilizers, fragrances, antimicrobial agents, other type of medicinal ingredients, and the like ingredients or additives or combinations thereof commonly added to alcohol gels or foams, aerosol compositions or to toiletries, cosmetics, pharmaceuticals and the like.
