  • Patent number: 10459424
    Abstract: Provided is a numerical controller capable of shortening cycle time while maintaining machining accuracy of a rigid tap. The numerical controller includes: a rigid tap control unit that executes a rigid tap by synchronizing rotational speed of a spindle with feedrate; a synchronization error monitoring unit that starts or terminates monitoring of a synchronization error between the rotational speed of the spindle and the feedrate at a point R set to a height equal to or higher than a top of a workpiece; and a workpiece top detection unit that detects a position of the workpiece top.

  • Patent number: 10245967
    Abstract: A system and method for managing vehicle charging stations such that when at least two of a plurality of electric vehicle charging stations (also known as electric vehicle service equipment, or EVSE) occupied with vehicles awaiting a charge, the present system manages the charging of individual vehicles in cases where the aggregated demand for charging exceeds the capacity of the circuits supplying the plurality of EVSE. By cycling so that only a few of the vehicles are charging at a time, the demand on the circuits is kept below a predetermined limit. In cases where a load shedding event is in progress, the limit can be further reduced. In cases where the cost of electricity is varying dynamically, the system considers a driver's explicit charging requirements (if any) and preferences for opportunistic charging when the price of electricity is not too high.

  • Patent number: 10126738
    Abstract: Methods and systems for improving tire uniformity through identification of characteristics of one or more candidate process effects are provided. The magnitudes of process harmonics associated with one or more candidate process effects can be identified by combining uniformity measurements for a set of tires to achieve an enhanced resolution for a sampling of the process harmonic. The enhanced resolution approach can combine uniformity measurements for a set of a plurality of tires that are slightly offset from one another to generate a composite process harmonic sampling. In particular, the composite process harmonic sampling can be generated by aligning the uniformity measurements for each tire in the set of tires based on the azimuthal location of the maximum magnitude of the process harmonic on each tire. The magnitude of the process harmonic can then be determined using the composite process harmonic sampling.

    Abstract: On receiving a request to reduce power consumption such as a request for power conservation, a power control device controls power used in a power consumption system including a plurality of devices so that a user can use enough consumable power while saving power in the most comfortable manner possible. The plurality of devices is classified into controllable devices and control-difficult devices. An information acquisition unit acquires amounts of power used by the controllable devices and an amount of most recently measured power of the entire power consumption system. When an amount of an upper limit power is set for the entire power consumption system, a demand control unit controls the amounts of power used by the controllable devices based on evaluation functions set for the respective controllable devices and differential equations set for the respective controllable devices.
