  • Patent number: 8828733
    Abstract: The compositions and methods relate to an organic polymer-inorganic particle sensor material for detecting analytes. Interactions between the polymer and the particles are affected by the presence of analyte, which displaces the polymer and increases its free volume. This change in free volume can be detected, e.g., using an embedded piezoresistive microcantilever (EPM) sensor. Analytes that can be detected include noxious substances, such as hydrogen cyanide gas and carbon monoxide.

  • Publication number: 20130156979
    Abstract: A columnar structure comprises a generally hollow laminate core, an outer composite skin, and a sleeve-like reinforcement. The sleeve-like reinforcement surrounds the laminate core and is sandwiched between the laminate core and the outer composite skin for reacting compressive loads imposed on the columnar structure.

  • Publication number: 20100143196
    Abstract: Microcantilever sensors having protected microcantilever arms are described. The sensors are well suited for analyte detection and measuring other small movements. The protected arm reduces damage due to handling and assists in assembly of the microcantilever sensor with a transducer.

  • Publication number: 20070249059
    Abstract: A device is disclosed which is a highly sensitive and selective sensor. The device is comprised of a sensor material secured into a fixed position on substrate, a deformable arm and a signaling component which creates a detectable signal in response to movement of the arm. The sensitivity of the device is enhanced by using a sensor material which undergoes a dramatic change in volume which may be accompanied by a phase change in response contact with a target such a molecule of interest. The selectivity of the device is enhanced by incorporating highly specific binding receptors (e.g. antibodies) into the sensor material which receptors bind to specific targets (e.g. peptide epitopes). The binding of the target molecule to the receptor causes the sensor material to change dramatically in volume thereby moving the arm causing the signaling component (e.g. a piezoresistor) to create a detectable signal (e.g. change in resistance) thereby indicating the present of the target.

  • Publication number: 20070104745
    Abstract: Aqueous dispersions of crystalline polymers based on hydrophobic monomers, preferably on a mixture of hydrophobic and hydrophilic monomers which contains a crosslinking monomer, particularly side chain crystalline (SCC) polymers. The dispersions are useful for providing coatings on substrates, particularly on seeds (whose dormancy is thus extended) and on fibrous substrates, particularly human hair (which thus becomes heat-settable).

  • Patent number: 7159498
    Abstract: The invention relates to an improved miter box for guiding a handheld portable circular saw. The miter box facilitates several conventional workpiece trim cuts using a handheld portable circular saw, including 45 degree and 90 degree straightcuts, as well as 45 and 90 degree straightcuts with a 45 degree undercut. The invention includes an I-beam that is formed from a rigid base plate having opposing first and second base plate edges disposed along its elongated length. A first and second flange can be respectively attached to the opposing first and second base plate edges. Each of the flanges can include a pair of opposing support faces. One or more transverse guide members can extend either 45, 135, or 90 degrees from one support face of the first flange to another support face of the second flange. The transverse guide member(s) and the support faces provide a friction reduced medium by which the bottom of a handheld portable circular saw's shoe can glide with greater ease and stability.

  • Patent number: 5809791
    Abstract: A process that converts heat energy to kinetic energy comprising at least two fluid cycles thermally joined in which these fluids act as refrigerants. An initiating cycle capable of performing reversed Carnot refrigeration is the major source of heat energy driving the process, and does so by giving off heat energy largely obtained through evaporating and superheating its fluid by condensing its fluid to a reclaiming cycle by causing said reclaiming cycle to boil its fluid, and this boiled fluid expands and moves invoking kinetic energy with the use of a turbine or similar means which is utilized by applicably selected means. The fluid in the reclaiming cycle is then condensed by giving off remaining heat energy and may comprise options of being recycled in the process, rejected out of the process, or used to drive additional reclaiming cycles, or another Remora II process.
