  • Patent number: 9955636
    Abstract: An irrigation mitigation runoff system that includes an irrigation system having at least one water outlet and a sensor that detects flow of water through a boundary. A controller is operatively coupled to the irrigation system and the sensor. Responsive to the sensor detecting flow of water through the boundary above a pre-defined threshold, the controller signals the irrigation system to pause irrigation.

  • Patent number: 8907604
    Abstract: An optimized pseudo-random period pattern can reduce audible noise in a system that includes an inverter circuit configured to provide power to an electric machine. A system can include a PWM optimization module (POM) comprising the PPP. A carrier period for a carrier signal used to provide PWM inverter drive signals can be selected in accordance with the PPP. The PPP can be expressed as an array of 200-400 elements, each element a period belonging to a finite set of 2 or more predetermined periods. A period can be selected by index from the array, and the index incremented to progress through the PPP, which can be repeated upon its completion. The PPP can be optimized to reduce audible noise while mitigating inverter losses. Modeling techniques can determine the number of array elements, the number of possible periods, and the period values that optimize the PPP.

  • Patent number: 4217780
    Abstract: A fluid sampling nozzle is spatially fixed, and adapted to be supplied by fluid to be sampled. A nearby actuating switch, manipulated by the operator, energizes a sequence of sampling, cleaning, and drying steps. In particular, once fluid is withdrawn, the sample is removed. A waste removal sink pivots to a point beneath the nozzle, and in a series of motions by a probe washer assembly, the nozzle is successively washed, inside and out. The apparatus is then returned to its initial position, ready for successive sampling operations.
