Title: Bicycle with rhomboidal gear
Inventor: RUNNELS DAVID J
IPC: B62M3/06
Filed: 1996-02-13
Abstract: A bicycle is disclosed with a rhomboidal (preferably 60<o> - 120<o>) drive sprocket gear (10) and a circular driven sprocket on the rear driven wheel (26). This gear arrangement varies the overall power input from the drive sprocket (10) to the driven gear (32). The shape of the drive sprocket (10) and the location of the drive pedal (27) changes the gear ratio so that a low gear ratio is utilized during the horizontal portion of movement of the cyclist's legs and a high gear ratio is utilized during the vertical movement of the legs. The gear ratio with the rhomboidal gear (10) is relatively constant during horizontal movement and abruptly changes at the approach to and during vertical movement of the cyclist's legs. While the rhomboidal gear is shown primarily for bicycles it may be used in other systems for converting reciprocal to rotary movement with a change in gear ratio. <IMAGE>

Title: Micromachined electrostatic actuator with air gap
Inventor: GOODWIN-JOHANSSON SCOTT HALDEN
IPC: G02B6/35
Filed: 2000-05-19
Abstract: A MEMS (Micro Electro Mechanical System) electrostatic device operated with lower and more predictable operating voltages is provided. An electrostatic actuator, an electrostatic attenuator of electromagnetic radiation, and a method for attenuating electromagnetic radiation are provided. Improved operating voltage characteristics are achieved by defining a non increasing air gap between the substrate electrode and flexible composite electrode within the electrostatic device. A medial portion of a multilayer flexible composite overlying the electromechanical substrate is held in position regardless of the application of electrostatic force, thereby sustaining the defined air gap. The air gap is relatively constant in separation from the underlying microelectronic surface when the medial portion is cantilevered in one embodiment. A further embodiment provides an air gap that decreases to zero when the medial portion approaches and contacts the underlying microelectronic surface. A moveable distal portion of the flexible composite is biased to curl naturally due to differences in thermal coefficients of expansion between the component layers. In response to electrostatic forces, the distal portion moves and thereby alters the distance separating the flexible composite from the underlying microelectronic surface. Structures and techniques for controlling bias in the medial portion and the resulting air gap are provided. The electrostatic device may be disposed to selectively clear or intercept the path of electromagnetic radiation. Materials used in the attenuator can be selected to pass, reflect, or absorb various types of electromagnetic radiation. A plurality of electromagnetic attenuators may be disposed in an array and selectively activated in subsets.

Title: Methods and apparatus for preventing rounding errors when transform coefficients representing a motion picture signal are inversely transformed
Inventor: SUZUKI TERUHIKO
IPC: H04N19/136
Filed: 1994-03-01
Abstract: Mismatch error occur in the local decoder of a MPEG-standard compressor for a motion picture signal, and in an MPEG-standard expander for a compressed motion picture signal. This is because of the lack of a standard for rounding results of *.5 (* is an integer) obtained when a set of transform coefficients resulting from compressing the motion picture signal is inversely orthogonally transformed. The invention prevents mismatch errors by preprocessing the set of transform coefficients prior to the inverse orthogonal transform. The transform coefficients in the set are summed, and the parity (odd or even) of the sum is judged. When the parity of the sum is judged to be even, the parity of one of the transform coefficients in the set is inverted to provide a parity-inverted transform coefficient. This makes the parity of the sum odd. Then, when the set of transform coefficients including the parity-inverted transform coefficient is inversely orthogonally transformed, none of the results of the orthogonal transform will have a value of *.5.

Title: Improved enhancement of chemiluminescent assays
Inventor: BRONSTEIN IRENA Y
IPC: C07C69/00
Filed: 1994-03-15
Abstract: Chemiluminescent bioassays for the presence or concentration of an analyte in a sample use 1,2-dioxetanes as substrates for the enzyme of an enzyme complex that bind to the analyte. The chemiluminescence obtained from the decomposition of the dioxetane triggered by the enzyme through the formation of the corresponding 1,2-dioxetane oxyanion of the enzyme complex is enhanced by the addition of TBQ as an enhancement agent. Other polymeric quaternary onium salts can be used as enhancement agents in conjunction with enhancement additives which improve the ability of the enhancement agent to form hydrophobic regions in the aqueous sample, in which regions the 1,2-dioxetane oxyanion and its chemiluminescent decomposition products can be sequestered. A kit for performing such assays is also provided.
