Abstract: A shoe automatic inflatable cushion system is applied to a shoe which includes a shoe body and a bottom part connected therewith. When a weight sensor disposed on the bottom part detects a load, a control module receives an enabling signal and accordingly drives an air pump to operate, so that an inflatable cushion disposed in the shoe body is inflated and expanded. When an air pressure sensor detects the pressure inside the inflatable cushion higher than a specified threshold interval, the air pressure sensor sends a disabling signal to the control module, and the control module receives a disabling signal and accordingly stops operation of the air pump.

Abstract: An air compression apparatus includes an air tank, an air compressor, and a governor. The air compressor delivers compressed air to the air tank by using power of an engine at the time of load running and stops the delivery of the compressed air to the air tank at the time of no-load running. The governor switches between the load running and the no-load running of the air compressor. Furthermore, the governor changes, when an engine speed is equal to or more than a threshold value, switchover timing for switching the air compressor from the no-load running to the load running in comparison with a time when the engine speed is less than the threshold value.

The system includes a pressurized gas tank (2) inside which is mounted a flexible bladder (4) which contains the primary fluid. The space between the gas tank and the bladder is considered a compression chamber (9) which contains a secondary fluid (7) that exerts pressure on the bladder to maintain a minimum pressure upon the primary fluid. The secondary fluid is supplied to and exits tank pressure chamber through a port (6). The flexible bladder is couple to inlet outlet port (8) extending to a pickup tube (10). The system also includes a pump (18), fluid reservoir (14), pressure relief valve (24) and controller (26) which functions to maintain the pressure of the secondary fluid. In a second embodiment, pressure is maintained through a second fluid absorbing and releasing material.

Abstract: An air compressor includes a tank unit that stores compressed air, a motor unit that generates compressed air to be stored in the tank unit, a pressure detection unit that detects a pressure value in the tank unit, and a control unit that drives the motor unit when a pressure value in the tank unit detected by the pressure detection unit is equal to or less than a motor start pressure value, and stops the motor unit when the pressure value in the tank unit detected by the pressure detection unit is equal to or greater than a motor stop pressure value. The control unit changes at least either of the motor start pressure value or the motor stop pressure value every time when a predetermined time passed.

Abstract: The controller for an actuator that is driven by a brushless motor estimates the temperature of the magnet in the brushless motor on the basis of an electric current value and a rotation speed thereof which are obtained by supplying power to rotate the brushless motor in a reverse direction, and limits current flowing through the brushless motor during forward rotation so as to prevent the magnet temperature from rising beyond an allowable maximum temperature. Limiting the current flowing through the brushless motor on the basis of the estimated magnet temperature makes it possible to drive the brushless motor while preventing the magnet temperature from rising beyond the allowable maximum temperature without providing the brushless motor with any temperature sensor for detecting the magnet temperature therein.
