  • Publication number: 20090078216
    Abstract: Methods and apparatuses are provided for deterring animals from entering or remaining in an area, comprising a motor which twists a twistable member, causing a noise generating member to generate noise by contacting the surface of a container, or a number of objects in the container. A method is also provided for deterring animals by generating randomly varying noises at randomly varying and aperiodic intervals. The method may further be implemented by causing an accumulation of torque in a twistable member, which at aperiodic or randomly varying intervals causes a noise generating member to move against a surface or against objects to produce randomly varying noises.

  • Publication number: 20080083618
    Abstract: Methods and devices for determining the concentration of a constituent in a physiological sample are provided. The blood sample is introduced into a test strip with portions of the blood sample being directed to both a first capillary and a second capillary. The first capillary configured to electrochemically determine a concentration of a first analyte in a blood sample by measuring a signal across a set of electrodes. The second capillary is configured to determine a hematocrit value of the blood sample by measuring a signal across a second set of electrodes.

  • Publication number: 20070089987
    Abstract: A system for measuring a glucose level in a blood sample includes a test strip and a meter. The test strip includes a sample chamber, a working electrode, a counter electrode, fill-detect electrodes, and an auto-on conductor. A reagent layer is disposed in the sample chamber. The auto-on conductor causes the meter to wake up and perform a test strip sequence when the test strip is inserted in the meter. The meter uses the working and counter electrodes to initially detect the blood sample in the sample chamber and uses the fill-detect electrodes to check that the blood sample has mixed with the reagent layer. The meter applies an assay voltage between the working and counter electrodes and measures the resulting current. The meter calculates the glucose level based on the measured current and calibration data saved in memory from a removable data storage device associated with the test strip.

  • Publication number: 20070048878
    Abstract: An improved multi-layered diagnostic sanitary test strip for receiving a heterogenous fluid, such as whole blood, to test for presence and/or amount of a suspected analyte in the fluid by facilitating a color change in the strip corresponding to the amount of the analyte in the fluid, wherein the test strip includes fluid volume control dams to prevent spillage of the fluid from the strip and a chemical reagent solution that facilitates end-point testing.

  • Publication number: 20070007126
    Abstract: A cylinder containing electrolyte is rotated at a very high speed, which facilitates dissociation of the electrolyte, producing oxygen and hydrogen as well as generating an increased potential difference between an insulated, central cathode and grounded, peripheral, multiple, moving anodes. When the anodes are close to the cathode, there is an easier rupture of the hydrated dipoles and separation into the component gases. As a central shell of hydrogen grows bigger around the cathode, the anodes, controlled by an electromagnetic device or mechanical gears move away from the cathode to the periphery of the cylinder, continually providing a short distance of migration of the described ions. As the molecules dissociate, the temperature drops. This collateral energy could also be used, adding to the efficiency of the apparatus.

  • Patent number: 5321945
    Abstract: The present invention relates to a distributed fuel system, wherein a plurality of fuel tanks used for storing fuel are distributed in different locations.The fuel tanks are connected to each other via a manifold which permits fuel to flow therein. The distributed fuel system includes a plurality of control components interposed at predetermined points of the manifold to permit or restrict the flow of the fuel contained in the manifold in response to control signals. A method for distributing the fuel between the fuel tanks to achieve predetermined levels in each of the fuel tanks comprises the steps of determining the status and condition of the fuel system. The functions to be performed are then selected. Based on the system status and the functions to be performed, the configuration of the control elements is selected to perform the functions to be performed.

  • Patent number: 4932871
    Abstract: A method for preparing chromogenic .alpha.-amylase substrate compounds at substantially high preparative yields in a relatively short period of time by the transglucosylation of a chromogenic glucoside compound to a maltooligosaccharide chain. The concentration of the maltooligosaccharide compound is greater than about 3 times the concentration of the chromogenic glucoside compound to result in at least about 50% of the chromogenic glucoside compound being converted to the desired chromogenic .alpha.-amylase substrate compound.

  • Patent number: 4823004
    Abstract: Methods and apparatus for interacting carriers with a structure of matter employ an electrode for emitting said carriers at a distance from a surface of that structure, and cause such carriers to travel along ballistic trajectories inside that structure by providing along the mentioned distance a gap for performance of a process selected from the group of carrier tunneling and field emission and injecting carriers emitted by the mentioned electrode and that process ballistically into the structure through the gap and the mentioned surface. The carriers are collected or analyzed after their travel along ballistic trajectories in the structure of matter. Pertinent information on the inside of the structure is obtained by conducting inside that structure what conventionally would have been considered external ballistics, while performing the carrier-propelling internal ballistics conversely outside that structure.
