  • Patent number: 10095256
    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.

  • Patent number: 10054932
    Abstract: One embodiment of the invention is a slicing engine that generates two or more slices of a virtual 3D model given a slice plane. The slicing engine then determines connection points on each of the slices that indicate how the 3D model is to be reconnected by the user when the 3D model is fabricated. The slicing engine also determines an optimized layout for the various slices of the 3D model on fabrication material for minimal use of the material. The user is then able to “print” the layout on the fabrication material via 3D printers, and connect the various printed slices according to the connection points to build a physical representation of the 3D model.

  • Patent number: 10042374
    Abstract: Method and apparatus are provided for determining a grid condition, such as a weakened grid condition, and controlling a power plant, such as a wind or solar power plant, in a manner which is appropriate to the grid condition. The method includes measuring (14) output parameters of a generator, such as a wind turbine or PV generator. The measured output parameters include reactive power and voltage. The method further includes determining (16) a relationship between the measured output parameters of the generator. The relationship between the measured output parameters of the generator is indicative of a condition of a power grid to which the plant supplies power. The method allows controlling (18) the plant responsive to the relationship between the measured output parameters of the generator to avoid onset of oscillatory behavior, which could otherwise occur in the power plant in the presence of a weakened grid condition.

  • Patent number: 10012974
    Abstract: A motor control system which makes a tool motor and a workpiece motor rotate in synchronization in a machine tool equipped with a tool motor, a workpiece motor, and a tool shaft movement motor which drives a linear shaft to change an intershaft distance between the tool shaft and the workpiece shaft, wherein when the power outage detector detects a power outage of the power supply during synchronous rotation of the tool motor and the workpiece motor, the operation of the forced deceleration circuit for causing forced deceleration of either one of the tool motor and workpiece motor is made to be delayed by a predetermined time and during that time the tool shaft movement motor is used to drive the linear shaft and separate the tool and workpiece as a retraction operation to thereby prevent damage to the tool and the workpiece at the time of a power outage.

  • Patent number: 9994118
    Abstract: Implementations of the present invention contemplate utilizing a communicative infrastructure represented by a telematics unit of an electric vehicle and a telematics service provider (TSP) communicatively coupled to the telematics unit to control an amount of power reserved for a charging event of the vehicle. Specifically, the TSP utilizes information provided by the telematics unit, electrical power utilities, and electrical power metering devices to determine the characteristics of electrical energy available for charging the vehicle. The TSP can utilize the characteristics of the available energy along with additional information, such as charging preferences established by a subscriber of the TSP and vehicle use schedules, to determine an amount of power to reserve for the charging event. The amount of power reserved for the charging event may be determined based on cost, greenhouse gas emissions, a combination thereof, and on other factors.

  • Patent number: 9948101
    Abstract: The systems and methods disclosed herein relate to management of peak electrical demand as registered by an electrical utility meter of an electrical utility customer. The metered demand level of the customer may be monitored over a first portion of a demand charge measuring period, then a cumulative amount of energy consumed by the customer in the first portion and a projected total energy consumed during the demand charge measuring period may be calculated. Next, an offset energy amount may be determined that is the amount required to bring a net amount of energy consumed by the customer during the demand charge measuring period to lie within a target value range for the demand charge measuring period. A power source such as a battery may then be controlled to provide the offset energy amount to the customer over a second portion of the demand charge measuring period.
