    摘要: A protecter for a riser connected to an underground water pipe and sprinkler head attached at a top portion thereof includes an elongate hollow body member having an upper portion with an upper opening and a lower portion with a lower opening, each opening being defined by a rim on respective upper and lower portion. The body defines an interior space for housing a riser and sprinkler head therein and has a lower portion including a pair of slots formed therein for fitting the body over an underground water pipe, and an upper portion further including a concave hood member extending laterally outwardly and downwardly of the rim of the upper opening and defining a cavity. The hood member has a lower edge portion for engaging a ground surface to limit downward travel of the protecter. The slots have an open lower portion and an arcuate upper portion for engaging the upper surface of an underground water pipe. The protecter also includes a plurality of spaced flanges extending beneath the hood member and engaged with the body to inhibit rotative motion of the hood member by positioning the flanges into a ground surface. The lower edge portion is located in a plane beneath an underground water pipe.

    摘要: A method for plant breeding by identifying, balancing, and combining multiple traits is provided. The method enhances the profitability of a hybrid corn seed production system by providing traits having high impact on decreasing cost of production on female parent and traits having low impact on decreasing cost of production and end users traits on the female and/or the male parent. The invention also provides a hybrid corn seed produced by such method.

    摘要: An occupancy sensor that provides improved performance by the inclusion of a microprocessor that controls the sensing transducers and processes the received signal to optimize desired detection performance. The occupancy sensor includes a quadrature detection technique and automatic sensitivity adjustment that reduce false detection caused by air flow, hallway traffic and other noise sources. A fault detection method executed periodically detects fault conditions in the sensor or sensing area caused by component failure or obstructions in front of the sensor. Transmitter power is varied depending on the size of the desired coverage area. Since various ambient parameters such as line voltage, light level, and temperature may be easily and usefully monitored, the microprocessor may use these variables to make intelligent decisions in controlling electrical loads, such as building lighting and ventilation.
