Abstract:
A load control system for controlling the amount of power delivered from an AC power source to a plurality of electrical load includes a plurality of energy controllers. Each energy controller is operable to control at least one of the electrical loads. The load control system also includes a first broadcast controller that has a first antenna and a second antenna. The first antenna is arranged in a first position and the second antenna is arranged in a second position that is orthogonal to the first position. The broadcast controller is operable to transmit a first wireless signal via the first antenna and a second wireless signal via the second antenna. Each of the energy controllers is operable to receive at least one of the first and second wireless signals, and to control the respective load in response to the received wireless signal.

Abstract:
Convenience of a control device for controlling an operating state of electrical equipment is enhanced. To achieve the enhanced convenience, a control device for controlling an operating state of electrical equipment includes a receiver, a tough-panel liquid crystal display, and an operation controller. The receiver receives power demand information transmitted from a broadcast station. The liquid crystal display receives user setting information indicating settings for operation of the electrical equipment. The operation controller controls the operating state of the electrical equipment in order to adjust power consumption of the electrical equipment, based on the power demand information received by the receiver and the user setting information input to the liquid crystal display.
Abstract:

Abstract:
A communication apparatus including a reception unit that receives a measurement value related to an amount of electric power, which is periodically transmitted to a first destination through a first pathway from an electric power meter through a second pathway that is different from the first pathway, and a transfer unit that transfers the received measurement value to a second destination that is different from the first destination, through a third pathway that is different from the second pathway.
Abstract:
This HEMS (200) is provided with a control unit (230) that, if an operation directive does not go through a server (600) provided externally to a customer's home (10), identifies said operation directive as having come from within the customer's home, and if the operation directive does go through the server (600) provided externally to the customer's home (10), identifies the operation directive as having come from outside the customer's home.
Abstract:
A controller includes a request acquisition unit that receives an operation permission request from a device, a calculation unit that calculates margin electric power derived from measurement by a measurement unit and an upper limit electric power, and a suppression unit that instructs the device to lower electric power consumption. When the margin electric power is less than the required electric power, the controller suppresses electric power consumption in devices in lower priority order stored in a priority storage unit within the suppression unit, such that electric power consumption increase in the management area may remain within the margin electric power. Then the controller issues the requesting device permission-or-denial for the operation, from the calculation unit.
Abstract:
A load control system for controlling the amount of power delivered from an AC power source to a plurality of electrical load includes a plurality of independent units responsive to a broadcast controller. Each independent unit includes at least one commander and at least one energy controller for controlling at least one of the electrical loads in response to a control signal received from the commander. The independent units are configured and operate independent of each other. The broadcast controller transmits wireless signals to the energy controllers of the independent units. The energy controllers do not respond to control signals received from the commanders of other independent units, but the energy controllers of both independent units respond to the wireless signals transmitted by broadcast controller. The energy controller may operate in different operating modes in response to the wireless signals transmitted by the broadcast controller.
