Method of enabling a wireless information device to automatically modify its behaviour
An end-user enters time sensitive information into an application; this, for example, may be an entry (e.g. ‘meeting’, or ‘lunch with Bob’) against specific times in an agenda or calendar application. Then, a different application on the device can utilize that information to modify the device behaviour appropriately. For example, say the ‘meeting’ in the calendar application is listed to last between 10 am and 11 am; then, during that hour, the telephone application in the device (that enables telephone functions of the device to be controlled) could automatically be set to a ‘silent’ profile so that the device does not ring on an incoming call, but instead only vibrates. |

Fuel cell system, control method for the fuel cell system, and vehicle equipped with the fuel cell system
A fuel cell system includes a fuel cell, a secondary cell, and a control portion that controls the amount of electricity generated when the fuel cell is started. A start-time target voltage is set so as to avoid the overcharged state of the secondary cell. A voltage adjustment portion that adjusts the output voltage of the fuel cell between an open-circuit voltage and a high-potential-avoiding voltage adjusts the amount of electricity generated at the time of starting the fuel cell, on the basis of the start-time target voltage. |

Voltage regulator for DC motors
A voltage regulator for a pair of electric motors has an input for a signal indicative of the desired speed for the motors and a pulse width modulation control circuit device. A control module provides a conditioning signal to the control circuit to output to the motors a square wave voltage having a duty-cycle which varies according to a predetermined function of the signal applied to the input of the regulator. The control circuit device has first and second electronic solid state switches associated with the motor and controlled by the control module. |

Electric power tool
An electric power tool includes a motor that rotary drives an output shaft; an operation unit to input a drive command of the motor; a torque setting device that sets an upper limit value of a rotational torque of the output shaft in accordance with a torque setting command; and a control device that drives the motor in one of a forward direction and a reverse direction in accordance with the drive command, and stops driving of the motor when the rotational torque of the output shaft has reached the upper limit value set by the torque setting device during driving of the motor. The torque setting device is configured to set the upper limit value such that the upper limit value during driving of the motor in the forward direction and the upper limit value during driving of the motor in the reverse direction are different. |

Method for starting an electronic drive circuit of an electric motor and circuit arrangement therefor
The invention relates to a method for starting an electronic drive circuit for the windings of an electric motor. A control unit, which is connected to a voltage source, is provided as well as a capacitor connected via a system switch element to the connecting terminals of the voltage source. The capacitor is connected across the input terminals parallel to the drive circuit. An operating circuit controls the system switch element. In order to start the motor, the operating circuit closes the system switch element and charges the capacitor and after the charging of the capacitor, opens the system switch element again. A test step is then started by the control unit, the drive circuit being supplied exclusively by the capacitor voltage (UC) during the test step. |

Motor drive apparatus
In a motor drive apparatus for driving a three-phase AC motor, a first mounting part of a heat sink is formed along an end. A second mounting part is formed in a direction perpendicular to the first mounting part and includes a first column part and a second column part. Three motor relay FETs are mounted on the first mounting part. Six inverter FETs and two power relay FETs are mounted on the second mounting part. Leads of the FETs are electrically connected to an electric circuit substrate. Heat generated by the FETs is radiated to the heat sink through an insulating and heat radiating sheet. By thus arranging the FETs, the motor drive apparatus is reduced in size. |
