Abstract: <P>PROBLEM TO BE SOLVED: To provide a position/speed sensorless controller which shortens a regenerating time at restart and lowers the possibility of tripping due to an overvoltage or reduces the capacity of a device for regeneration.  <P>SOLUTION: This controller performs current control which gives a zero current command to a current control system for a PM motor 7 by switching changeover switches 13A and 13B in the idling state of the motor at restart from the idling state of the PM motor. A second magnetic pole position estimating calculation part 14 multiplies a qc-axis voltage command on the control axis of the current control system by a gain to convert it into a frequency, makes the converted frequency as the output frequency of a power converter, and integrates the output frequency to get a phase. The changeover switch 13C switches the phase obtained by the second magnetic pole position estimating means used in the zero current command control into the phase estimated by a first magnetic pole position estimating calculation part after phase stabilization by the first magnetic pole position estimating calculation part 11 becomes stable during the period of zero current command control.  <P>COPYRIGHT: (C)2004,JPO

IPC: G06F21/88
Filed: 2002-08-12
Abstract: PROBLEM TO BE SOLVED: To provide a method and device for theft protection of electronic apparatuses connected to a bus system suitable for use in a digital home network. SOLUTION: At least one of the apparatuses in the network is equipped with a monitoring unit which can be switched between an activated and a de-activated state. In the activated state, the monitoring unit monitors the occurrence of a bus reset which is generated particularly when removing an apparatus from the network. After the occurrence of such a reset, the monitoring unit compares the list of all apparatuses on the bus with a list generated and stored before the reset. When determining differences, an alarm is triggered which can be reproduced particularly by means of the apparatuses which are present, such as, for example, televisions and hi-fi equipment. Furthermore, a separated apparatus can recognize a possible theft by comparing the configuration of the previous bus system with a new bus system into which the apparatus is introduced and subsequently activate a blockade of its own functions.
