An LED lighting device comprises: a thermally conducting body having an at least one opening that connects with a cavity within the body and a plurality of LEDs mounted in thermal communication with a face of the body and positioned around the opening. One or more passages pass through the body from the cavity to an outer surface of the body and are configured such that in operation air moves through the cavity by thermal convection thereby to provide cooling of the body. Each passage is configured in a direction that extends in a direction at an angle of about 45° to a line that is parallel with the axis of the body toward the outer surface of the body away from the face. The body can be configured such that its outer surface has a form factor resembling an incandescent light bulb or halogen reflector lamp.

Thermoelectric devices having enhanced thermal characteristics are fabricated using multilayer ceramic (MLC) technology methods. Aluminum nitride faceplates with embedded electrical connections provide the electrical series configuration for alternating dissimilar semiconducting materials. Embedded electrical connections are formed by vias and lines in the faceplate. Methods are employed for forming tunnels through lamination and etching. A portion of the dissimilar materials are then melted within the tunnels to form a bond. Thermal conductivity of the faceplate is enhanced by adding electrically isolated vias to one surface, filled with high thermal conductivity metal paste. A low thermal conductivity material is also introduced between the two high thermal conductivity material faceplates. Alternating semiconducting materials are introduced within the varying thermal conductivity layers by punching vias within greensheets of predetermined thermal conductivity and filling with n-type and p-type paste. Alternating semiconducting materials may also be patterned in linear or radial fanout patterns through screening techniques and lamination of wire structures. A liquid channel within the faceplate is used to enhance thermal energy transfer. Thermoelectric devices are physically incorporated within the IC package using MLC technology.

A camera based vision system that recognizes and maximizes belt area utilization. A plurality of cameras are positioned at flow entry points of feed conveyors and at the singulator. The control algorithm recognizes individual items area, the rate at which individual objects are passing, and the area utilization of the collector belt. The video camera and computer based conveyor package management system monitor and control the number and size of the packages present on the infeed conveyors, collector conveyor, singulator conveyor and sorting conveyor in a package handling system wherein the camera data is used to measure the available area or space on the conveyors to maintain a desired density of packages on selected conveyor(s). The conveyor speed is controlled as a function of occupancy on a collector or just prior to a singulator or receiver.

A supplemental gas delivery device is described for a mask assembly having at least one supplemental gas port, the at least one supplemental gas port including an aperture in communication with an interior of the mask assembly. The mask assembly may include an aperture communicating with an interior of the mask assembly, and a cannula for communicating with the supplemental gas port. The cannula is positioned to deliver supplemental gas adjacent to the patient's nares and / or mouth, to increase an efficacy of treatment for the patient by more directly applying the flow of supplemental gas to the patient's nares. An optional bridging portion may be included to provide a connection between supplemental gas port and the cannula.

Cross stream thrombectomy catheter and system for fragmentation and removal of thrombus or other material from blood vessels or other body cavities. High velocity saline jets emitted from a toroidal loop jet emanator or other jet emanator in a catheter distal end entrain fluid through inflow orifices, and with flow resistances create a back-pressure which drives cross stream streams through outflow orifices in a radial direction and thence radially and circumferentially to apply normal and drag forces on thrombotic deposits or lesions in the blood vessel or other body cavity, thereby breaking apart and transporting thrombus particles to be entrained through the inflow orifices, whereupon the high velocity jets macerate the thrombus particles which then transit an exhaust lumen or recirculate again via the outflow orifices.

A tamper-evident package with pressurized contents which includes a closure and associated container which cooperate to provide desired tamper-evidence upon initial removal of the closure from the container, while promoting convenient and comfortable removal and use by consumers.

An improved venturi apparatus for the incorporation of air into a liquid. The preferred embodiment of the invention comprises an entry section, a cylindrical section, and an outflow section. Lateral tubes extend from the cylindrical section so as to form an acute angle relative to both the central and cross-sectional axes of the cylindrical section, thereby preventing leakage of liquid out through the lateral tubes during use and subsequent handling. The entry section includes a breather tube connected to the cylindrical section.

A metal cutting drill bit has a shank portion, a flute portion defining a helix angle and a tip. The tip has a primary cutting edge extending to an outer periphery of the drill bit. The primary cutting edge has a rake face defining a rake angle. The rake angle is different from the helix angle at the tip of the drill bit.

A rotary adsorber for continuous bulk separations is disclosed. The rotary adsorber includes an adsorption zone in fluid communication with an influent adsorption fluid stream, and a desorption zone in fluid communication with a desorption fluid stream. The fluid streams may be gas streams or liquid streams. The rotary adsorber includes one or more adsorption blocks including adsorbent structure(s). The adsorbent structure adsorbs the target species that is to be separated from the influent fluid stream. The apparatus includes a rotary wheel for moving each adsorption block through the adsorption zone and the desorption zone. A desorption circuit passes an electrical current through the adsorbent structure in the desorption zone to desorb the species from the adsorbent structure. The adsorbent structure may include porous activated carbon fibers aligned with their longitudinal axis essentially parallel to the flow direction of the desorption fluid stream. The adsorbent structure may be an inherently electrically-conductive honeycomb structure.
