Therefore, a probability of a false warning can be reduced.

Abstract: A wheel condition-monitoring system comprises transmitters (1) installed on individual rotatable wheels, for transmitting conditions of the wheels, and a receiver (11) installed on the side of a vehicle body, for receiving the conditions of the wheels sent from the transmitters. The rotation speed of the wheels are detected, and data that indicate the conditions of the wheels are sent from the transmitters (1) to the receiver (11) at intervals in accordance with the rotation speeds detected, or data that relate to a pressure etc. are sent for a predetermined number of times at a transmission interval of a first cycle that assumes a high speed range. At the same time, data transmission of a predetermined number of times corresponding to the transmission interval of the first cycle is repeated for a predetermined number of times at a transmission interval of a second cycle that assumes a low speed range and is longer than the first cycle.

Abstract: The sensor unit is operated based on a first timing signal with a first interval. If there is no second timing signal with a second interval longer than the first interval, a tire internal-pressure information signal is transmitted when the alarm device judges a moving of a vehicle based on a signal from the tire rotational-movement detecting means, the signal having the tire internal-pressure data with a start bit, and the transmission of the tire internal-pressure information signal is stopped when the device judges a non-moving of said vehicle. If there is the second timing signal, the tire internal-pressure information signal is transmitted when the device judges the moving of the vehicle and N pieces of tire internal-pressure information signals are transmitted at third intervals (N is a natural number not less than 2) when the device judges a non-moving of the vehicle, each tire internal-pressure information signal having the tire internal-pressure data with said start bit.

Abstract: A vibration isolating apparatus and a vibration isolating table for reliably controlling vibration of an object of vibration isolation. A coil-mounting main body is mounted on the vibration isolating table and a yoke-mounting main body is mounted on a floor. A coil of the coil-mounting main body is disposed in a gap of a yoke where magnetic flux passes through, in a state in which the coil does not contact the yoke. An acceleration sensor for detecting a vibration is mounted on the vibration isolating table and is connected to a controlling device. The controlling device receives an acceleration detecting signal from the acceleration sensor and controls an electric current applied to the coil such that vibration acting on the vibration isolating table becomes zero.

Abstract: Disclosed is a vibration control method being largely effective in vibration-proof even when a natural frequency is relatively low and its transmissibility of vibration is high and being thus effective in reducing vibration in a wide range of frequencies; and its apparatus. In the above method, vibration information of a vibration source as a reference signal and vibration information of a vibration-proof object as an error signal are inputted into an adaptive filter. The reference signal is processed by regenerating a filter coefficient on the basis of adaptive algorithm, to form a feedforward signal. In the other hand, vibration information of the vibration-proof object is inputted in a feedback calculating means, and a feedback control signal is formed on the basis of a feedback control rule. The feedforward control signal and the feedback control signal are synthesized, to form a drive signal for a vibration exciting means.
