Abstract: An active vibration insulator includes an electromagnetic actuator, a control-signals generating device, a driver, a calculator, and a judging device. The electromagnetic actuator generates vibrating forces depending on electric-current supplies. The control-signals generating device generates cyclic control signals based on cyclic pulsating signals output from a vibration generating source of a vehicle. The cyclic control signals actively inhibit vibrations generated by the vibration generating source from transmitting to a specific part of the vehicle. The driver drives the electromagnetic actuator by making the electric-current supplies variable based on the cyclic control signals. The calculator calculates an estimated transfer function composed of estimated values of a transfer function for a transfer system including the electromagnetic actuator and the driver. The judging device judges an inoperative malfunction of the electromagnetic actuator based the estimated transfer function.

Moreover, the actuating-signal output device outputs a signal for turning off one of them, and outputs a pulse-width-modulated actuating signal for actuating the other one of them by means of pulse-width modulation when the cyclic control signals are negative.

Abstract: An active vibration insulator includes an electromagnetic actuator, a controller, and a bad-roads processor. The electromagnetic actuator generates vibrating forces depending on electric-current supplies. The controller carries out vibrating-forces generation control. In the vibrating-forces generation control, the electric-current supplies are made variable so as to actively inhibit vibrations generated by an on-vehicle vibration generating source of a vehicle from transmitting to a specific part of the vehicle based on cyclic pulsating signals output from the on-vehicle vibration generating source. Thus, the controller lets the electromagnetic actuator generate the vibrating forces. The bad-roads processor stops the vibrating-forces generation control effected by the controller when the vehicle travels on bad roads.

A group management server places a plurality of content processing apparatuses in terms of a unit of an owner into a group registration and issues a notification of a group ID of the group. A content recording apparatus adds a recorder ID thereof to production content produced thereby. Further, a content reproduction apparatus controls reproduction of content based on a recorder ID read out from content and a reproduction permission ID list. If the different processing apparatuses have the same group ID, the recorder ID can be added to the reproduction permission ID list.
