  • Patent number: 11719213
    Abstract: Systems and methods for preventing activation of a starter when engine speed is above a threshold engine speed value are disclosed. In examples, an engine driven power system includes an engine and a current transformer to generate an induced current in response to an excitation current from an excitation circuit. As the excitation current is induced in response to rotational movement of the engine, the excitation current and the induced current exhibits characteristics corresponding to engine speed. A control circuit receives a signal from the current transformer representing characteristics representative of engine speed and determines the engine speed, compares the characteristics to a list of values that correlates current characteristics to engine speed, compare a list of threshold engine speed values to the calculated engine speed value, and prevents activation of an engine starter if the control circuitry determines that the engine speed exceeds the threshold engine speed value.

  • Publication number: 20150203860
    Abstract: Methods and compositions for increasing the starch content in green tissues of a plant are provided. The method comprises down-regulating me activity of starch degradation enzymes in a plant. The resulting transgenic plants of the invention have increased starch content in green tissues and exhibit a starch excess phenotype. In one embodiment the method involves manipulating a monocot plant to down-regulate the activity of a starch degradation enzyme. The plants are useful for improving the yield of free sugars from plant biomass and increase dried green tissue storage stability.

  • Patent number: 8167483
    Abstract: Temperature measurement instruments and methods are provided for visually identifying a selected area of a target with a light beam. After imaging infrared radiation from a measurement area on a target, a selected area satisfying a temperature criterion is determined. An actuator system moves a light beam relative to the instrument and measurement area to visually identify the selected area. In some embodiments the actuator system may repeatedly move the light beam to visually identify the selected area of the target as the instrument is moved and the selected area's position changes within the measurement area.
