  • Publication number: 20160360467
    Abstract: A relay device communicably connects an upper-level air conditioning system and a lower-level air conditioning system that use different protocols. An upper-side communicator is connected to a first bus, and transmits and receives communication packets to and from the upper-level air conditioning system. A lower-side communicator is connected to an outdoor device that is a master device, and transmits and receives communication commands to and from the lower-level air conditioning system. An association information memory stores association information obtained by associating an address in the upper-level air conditioning system allocated to each device in the lower-level air conditioning system with identification information on each device in the lower-level air conditioning system. A processor performs a mutual conversion on the communication packets and the communication commands based on the association information stored in the association information memory.

  • Patent number: 9383438
    Abstract: A presence detection system is equipped with a transmitter that transmits a multipath wireless signal and a receiver that detects the presence of a person by receiving the transmitted wireless signal, within a prescribed space. On the basis of the reception level for a wireless signal received intermittently at the beginning of a first interval, the receiver determines whether there has been a change in the present/absent state of a person. When it is determined that there has been a change in the present/absent state of a person, the receiver determines whether a person is present/absent on the basis of variation in the reception level for a wireless signal received at the beginning of a second interval, which is shorter than the first interval.

  • Publication number: 20160147295
    Abstract: An inclination of a first unit is detected based on an output from a first acceleration sensor provided in a first unit of a controller, and an inclination of a second unit is detected based on an output from a second acceleration sensor provided in a second unit separate from the first unit. A difference between the inclinations of the first unit and the second unit is detected, and game control is performed using the detected difference. Thus, with a game apparatus using a plurality of acceleration sensors or a plurality of sensors capable of detecting a motion or a posture, a dynamic play is made possible with a high degree of freedom of motion and an intuitive motion input is realized.

  • Publication number: 20160105019
    Abstract: A current path of a first transistor is connected in series to a communication line. When the electric current through the current path of the first transistor becomes equal to or greater than a set electric current, a current-limiting controller limits the electric current through the current path by controlling the first transistor to increase the resistance of the current path. When the end-to-end voltage of the current path of the first transistor becomes equal to or greater than a set voltage, a load limiter switches the first transistor off.

  • Publication number: 20160091538
    Abstract: A power measurer measures, for each current transformer CT, electric energy supplied to equipment or electric energy supplied from the equipment based on a current measured by a current measurer and a voltage measured by a voltage measurer. A sign memory stores, for each current transformer CT, information indicating whether the electric energy measured by the power measurer when the current transformer CT is disposed in a correct direction on a power line shows a positive sign or a negative sign. A determiner determines that, when the sign stored in the sign memory differs from the sign of the electric energy measured by the power measurer, the current transformer CT is disposed in an incorrect direction on the power line.

  • Publication number: 20160054359
    Abstract: This current measurement device includes a conductor, a first terminal block, a pair of detection coils and a current calculator. A magnetic field, proportional to the magnitude of a conducted to-be-measured current, is generated around the conductor. The first terminal block has a placement surface on which the conductor is disposed. The pair of detection coils has the configuration, connected in series and in opposite polarities, and disposed on the placement surface of the first terminal block such that the conductor is between the pair of detection coils, and each coil is spaced from the conductor by an insulating distance. The detection coils output an inductive voltage signal produced by the magnetic field generated by the conductor and an external magnetic field which is magnetic noise. A current calculator calculates the value of the to-be-measured current on the basis of the inductive voltage signals from the pair of detection coils.

  • Publication number: 20150377939
    Abstract: A voltage/current verifier computes, for each phase, a phase difference between phase voltage and phase current from the phase of phase voltage and the phase of phase current computed for each phase by a phase acquirer, and determines conformity if all of the computed phase differences are within a preset range. A current/current verifier computes phase differences between phase currents from the phase of phase current computed for each phase by the phase acquirer, and determines conformity if all of the computed phase differences are less than 180°. A reporting device reports that a current transformer is incorrectly placed on a power line unless both the voltage/current verifier and the current/current verifier do not determine conformity.
