    Abstract: An anti-cycling luminaire control system may detect repeated lamp-off conditions and interrupt power to the lamp and provide an indication of lamp cycling after a predetermined number of lamp-off conditions has been detected. The control system also provides a cool-off period after a lamp-off cycling event is detected during which time restarting of the lamp is inhibited. If the lamp does not restart after multiple restart attempts and cool-off periods, the system determines that a fault condition exists, and may provide a fault alert. The system may provide for shut-off or dimming of the lamp during the night after a portion of the night has passed. This delayed turn-off may be varied according to the length of the night. Starting and dimming the lamp at a zero voltage crossing of the line current can reduce stress on luminaire and control system components and reduce maintenance.

A command signal is directly transmitted to a controller as a target command increment value. A compensation signal arithmetic unit receives the target command increment value, subtracts the target command increment value from a signal having passed through an inverse transfer function unit having an inverse transfer function characteristic of any low-pass filter, and sends a compensation signal generated by multiplying a result of that subtraction by an adjustment gain to a controlled object. The controller receives the target command increment value and an output increment value of the controlled object, and sends a control input to the controlled object so that the output of the target command becomes coincident with the target command.

    Abstract: A human-machine interface assembly includes a user interface, a first motor, a second motor, a first sector gear, and a second sector gear. The user interface is configured to rotate about a first rotational axis and a second rotational axis that is perpendicular to the first rotational axis. The user interface is responsive to an input force to rotate about one or both of the first and second rotational axes. The first motor is disposed apart from the first rotational axis and generates a drive force about a third rotational axis that is parallel to the first rotational axis. The second motor is disposed apart from the second rotational axis and generates a drive force about a fourth rotational axis that is parallel to the second rotational axis. The first sector gear is coupled between the first motor and the user interface, and the second sector gear is coupled between the second motor and the user interface.

  • Publication number: 20080111516
    Abstract: In a system for controlling rotation of a rotor of a multiphase rotary electric machine in relation to a stator thereof, a superimposing unit superimposes a first frequency signal on the input signal to the multiphase rotary electric machine. The first frequency signal has a first phase and a first period, and the first period is different from a period of rotation of the rotor. An amplitude detector detects an amplitude of a second frequency signal. The second frequency signal is actually propagated in the multiphase rotary electric machine with a second phase based on the superimposed first frequency signal. A rotation angle determiner determines a rotation angle of the rotor so as to eliminate a difference between the detected amplitude of the second frequency signal and a predetermined target amplitude thereof.

    Abstract: A charge controller that includes an input interface that receives input DC electrical signals. A converter section converts the input DC electrical signals to output DC electrical signals. Control means is operably coupled to the converter section. The control means includes means for operating the converter section at an estimated maximum power point of the input DC electrical signals. The estimated maximum power point is derived by a novel control scheme that quickly adapts to changing conditions and thus affords optimum energy harvest from the source and improved energy conversion efficiencies.

    Abstract: A battery pack having a secondary battery; a measurement unit measuring a terminal voltage and a current of the secondary battery; a protection unit preventing the secondary battery from being overcharged when the terminal voltage measured by the measurement unit is equal to or higher than an overcharge detection voltage; and a control unit receiving the terminal voltage and current measured by the measurement unit, the control unit having a first mode and a second mode in which current is less consumed than the first mode. A voltage in a range of from a full charge voltage to less than the overcharge detection voltage is defined as a voltage threshold. The control unit changes from the first mode to the second mode when a state in which a transition requirement is satisfied lasts for a predetermined period of time.
