  • Patent number: 6742582
    Abstract: An apparatus for internal climate control. The apparatus comprises an inlet and outlet for air, a tangential fan that rotates about a vertically oriented axis, a fan coil assembly through which air is circulated by the tangential fan from the inlet to the outlet, a barrier to prevent recirculation of the air within the apparatus after it is circulated over the fan coil assembly, and a joint to provide fluidic communication with a source of recirculating fluid. The fan coil assembly is connected in series to the source of recirculating fluid and provides thermal communication between the recirculating fluid and the circulating air.

  • Patent number: 6696299
    Abstract: A photoactive moiety exhibiting an anisotropic transition dipole. The moiety exhibits emission of polarized light in response to energy absorption. In a preferred embodiment, the moiety comprises a particle from the group consisting of a crystalline arrangement of photoactive molecules and a photoactive nanocrystal. The moiety may include a matrix in which photoactive objects exhibiting an anisotropic emission dipole are embedded. The moiety may be photobleached to product the anisotropy and the photoactive objects may have a one dimensional transition dipole in their natural state.

  • Patent number: 6601257
    Abstract: A jewelry brush that exhibits improved jewelry cleaning and includes a plurality of bristles divided into at least two zones. Each zone has characteristics including a surface profile directed to cleaning a particular jewelry profile. The characteristics include modified bristle length, material characteristics, angle, grouping and grouping shape. Additional embodiments of the invention may further include additional zones of bristles trimmed with additional surface profiles. In addition, the brush can be constructed to include a bottle cap in the handle portion, allowing the jewelry brush to be include and retained in a bottle that itself may contain cleaning fluids.

  • Patent number: 6569654
    Abstract: Compositions, methods and systems are provided for the stimulation of biological activities within stem cells by applying electromagnetic stimulation to an electroactive material, wherein the electromagnetic stimulation is coupled to the electromagnetic material. In general the present invention involves attaching or associating the desired cells to or with a surface comprising an electroactive material, and applying electromagnetic radiation directly to the desired area. In preferred embodiments, the stimulation of biological activities within cells results from inducing one or more activities including, but not limited to, gene expression, cell growth, cell differentiation, signal transduction, membrane permeability, cell division, contraction, and cell signaling.

  • Patent number: 6523907
    Abstract: An apparatus and method for producing brushes. The bristle bundles are loaded into a magazine which includes part of a cavity for an injection mold. The magazine is mated with the remainder of the injection mold and the brush handle injection molded around the bristles. The bristles may be profiled, trimmed, end-rounded, fused, or otherwise processed before the handle is injection molded. In addition, the handle of the brush may be formed in two injection molding steps of two different materials. An apparatus is taught which enables the brush to be produced, optionally ornamented, and packaged on a single machine.

  • Patent number: 6488017
    Abstract: An improved spark ignition system. Pressure on a piezoelectric element results in a voltage that, when discharged across a spark gap, causes dielectric breakdown in a fuel air mixture. Additional current to power combustion is supplied by a capacitor circuit. The ignition system increases the combustion rate and decreases emissions of NOx.

  • Patent number: 6485105
    Abstract: A method and apparatus for feeding bristle bundle material into a magazine. The magazine is used in the production of brushes in which not all the bristle bundles extend in the same direction from the face of the brush. The feed apparatus for guiding the bristle bundle material from a supply to the magazine includes a number of transition plates having channels machined at an oblique angle to the surface of the plate. The plates each guide the bristle bundle material through a small angle; the assembled plates can guide the material through a large total angle so that the angle at which the bristle bundles enter the magazine is the same as the angle the bristles will have with respect to the brush.

  • Patent number: 6440389
    Abstract: A fluorescent agent for monitoring organ function, such as glomerular filtration, renal blood flow, or hepatic function. The agent is injected into a subject and the fluorescence monitored in vivo via time-resolved fluorescent techniques. The agent is a lanthanide ion chelated to a polyaminopolyacetic acid analog. A new clearance agent is also proposed based on a tetraazamacrocycle. Such a clearance agent also finds applications in other fields where fluorescence detection is exploited.

  • Patent number: 6305416
    Abstract: Hydraulic actuator. An actuator body includes an inlet, an outlet, a port communicating with a pre-charged diaphragm tank, and a port communicating with a pressure switch. The actuator body includes a movable member which, in a first position, closes the inlet port and provides fluidic communication with the pressure switch port while allowing pressure equalization between the inlet and an interior of the actuator body. In a second position, the movable body opens the inlet port and seals the pressure switch port. A spring is disposed within the actuator body to urge the movable member toward the first position. The invention eliminates the need for multiple springs as shown in one prior art design and eliminates the need for reliance on a hydrostatic force differential to move the movable member.

  • Patent number: 6306142
    Abstract: A system for transplanting a bone plug from a donor site to a recipient site extracts the bone plug from the donor site, and then places a bone plug delivery device having a tip which is at least translucent and, preferably, clear over a tube containing the bone plug. The tip is then placed substantially over a pre-formed hole in the recipient site, whereafter the bone plug is forced from the tube, through the transparent tip, and into the pre-formed hole.
