Title: Remote supervisory and controlling equipment
Inventor: NAGASAWA HIROSHI
IPC: H04Q9/00
Filed: 1986-05-22
Abstract: PURPOSE:To shorten time required for troubleshooting by issuing the alarm when there is a logical conflict between the contents of a control command from a master station and the state of a device on a slave station side, transmitting the states of equipments configuring a slave station as stored information and checking them. CONSTITUTION:In case of abnormality such as control jamming, the operation is normal until an 'input' control signal is transmitted to a comparator B11. However the current state of the equipment is actually in an 'input' state, and information showing the effect is transmitted to the comparator B11. In such case, conditions that the control command is an 'input' control in the comparator B11 and the current state of the equipment is 'input' hold are satisfied. Here an arithmetic processing circuit B3 outputs an alarm signal to the display panel A1 in the master station A through a code output circuit B7, a modulator circuit B8, a transmission line L2, a demodulator circuit A10 and a code reception circuit A9, and the display panel 1 warns. Simultaneously the contents in a memory B4 storing the state of the equipment in the slave station B are transmitted to the side of the master station A through the route the same as the alarm signal. Thus the troubleshooting of control jamming can be made easily and quickly.

Title: Method and device for active muffling for vehicle
Inventor: SEKIGUCHI OSAMU
IPC: G10K11/16
Filed: 1993-05-21
Abstract: PURPOSE:To effectively continue a muffling operation by predicting the level of the rapid change in a reference signal at a certain degree in advance with a preview sensor when the reference signal is rapidly changed. CONSTITUTION:At the time when the state of a road has suddenly changed, preview sensor outputs 10 and 11 are digitized by an A/D converter 60, this preview sensor is monitored, and muffling control is stopped only in a block where the preview sensor signal rapidly changes. The state of the road can be speedily grasped since the preview sensors 10 and 11 are arranged before a vibration sensor fitted to a suspension. Therefore, since it is shown that the outputs of acceleration sensors 20-23 are enlarged when the outputs of the preview sensors 10 and 11 rapidly change, no second-order sound is outputted and the muffling device does not run away by turning the respective values of coefficients for the adaptive filter of the muffling device to zero.
