    摘要: Electrode structures for transvascular nerve stimulation combine electrodes with an electrically-insulating backing layer. The backing layer increases the electrical impedance of electrical paths through blood in a lumen of a blood vessel and consequently increases the flow of electrical current through surrounding tissues. The electrode structures may be applied to stimulate nerves such as the phrenic, vagus, trigeminal, obturator or other nerves.

    摘要: Microstructures can be formed as patterned layers on a substrate and then erecting the microstructures out of the plane of the substrate. The microstructures may be formed over circuits in the substrate. In some embodiments the patterned layer provides resiliently-flexible members such as cantilevers or springs that can be buckled to permit an edge defined by the patterned layer to engage a surface of the substrate. In some embodiments deformation of the resiliently-flexible members results the edge being forced against the substrate. Such microstructures may be applied in a wide range of applications including supporting optical elements, sensors, antennas or the like out of the plane of a substrate. Examples of accelerometer structures are described.

    摘要: Methods for detecting defective pixels in imaging arrays involve establishing probabilities that individual pixels are defective and updating those probabilities by analysing images acquired by the imaging arrays. Probabilities may be evaluated for each of two or more defect conditions. The methods may be used to detect defects such as stuck-low, stuck-high, high-sensitivity, low sensitivity, hot, and defect-free conditions. Other more complicated defect conditions can also be detected. Apparatus for detecting defective pixels may be integrated with a camera or other imaging device or provided separately.

    摘要: A vein locator comprises an energy source for directing incident energy toward organism tissue. At least a portion of the incident energy is reflected from structures within the organism tissue as reflected energy. The vein locator comprises an energy detector connected to detect energy reflected from the organism tissue. The incident energy is moved across a scan region a first time and the energy detector produces a corresponding first signal representative of at least one characteristic of the first reflected energy. A controller receives the first signal, identifies an extremum in the first signal and determines a threshold level based on the identified extremum. The incident energy is then moved across the scan region a second time and the energy detector produces a corresponding second signal representative of at least one characteristic of the second reflected energy. The controller compares the second signal to the threshold level to determine whether a current location of the incident beam represents a location of a vein.

    摘要: This application relates to a process for controllably placing two or more microspots on a target substrate in close proximity to one another. The microspots may then be simultaneously irradiated and the resulting ions detected by mass spectrometry, such as time of flight mass spectrometry. In one embodiment the size and spacing of the microspots on the substrate may be controlled by using an electrodynamic balance during the deposition step. The deposition procedure ensures that at least some of the microspots are spaced-apart on the substrate a distance less than the focused output of a single laser. Simultaneous irradiation of the adjacent microspots may cause desorption plumes of the microspots to interact in a gas phase, such as by ion-molecule reactions. The microspots may be configured to improve the ionization yield of the sample material in the gas phase and/or to increase the frequency of ion-molecule collisions in the gas phase. This allows for desorption of particular classes of compounds to be optimized independently of ionization. Different microspots could include different amounts or types of matrix compounds to enable simultaneously detection of compounds of varied physical and chemical properties within the same sample. One or more of the microspots may include calibrants or other additives for improving detecting accuracy or quantitation. Organized array of closely packed microspots may be created for use as standard reference materials or analyte detectors.

    摘要: This invention relates to novel photochromic and electrochromic monomers and polymers based on 1,2-dithienylcyclopentene derivatives and method of using and synthesizing same. The compounds are reversibly interconvertible between different isomeric forms under suitable photochromic or electrochromic conditions. The electrochromic conversion may be catalytic. The application also relates to ultra-high density homopolymers prepared using ring-opening methathesis polymerization (ROMP) where the central ring of the 1,2-bis(3-thienyl)-cyclopentene is incorporated directly into the polymer backbone. The monomer units may be readily functionalized to enable the synthesis of polymers with diverse structural and electronic properties. The compounds have many potential applications including high-density optical information storage systems, photoregulated molecular switches, reversible holographic systems, ophthalmic lenses, actinometry and molecular sensors, photochromic inks, paints and fibers and optoelectronic systems such as optical waveguides, Bragg reflectors and dielectric mirrors.
