Abstract: A technique for determining particulate density in a fluid monitors the changes in the speed of sound. Since the speed of sound is intimately related to the composites of the air mixture and since the speed of sound of clean air at any temperature and humidity can be calculated exactly, it is possible to estimate the density of any foreign particulates in the air by observing changes in the speed of sound. Formulations are derived that correlate the change in the speed of sound of the air mixture to their density fluctuations, thus allowing people to estimate the mass density of foreign particulates under any temperature and humidity. Alternatively, the change in density of the air mixture can be detected, thereby indicating the presence of contaminants and a possible alarm, even if the contaminants are not yet identified.

The tire deflation warning system can prevent a deflation alarm for a vehicle with a heavy load.

The clutch facilitates transfer of power to an output gear stage when the actuator motor is energized, but disengages the output gear stage when the actuator motor is de-energized.

Abstract: In association with a solenoidal coil 10 being energized to unlock a shift lever, a first movable core 9 and a second movable core 11 magnetically stick together so as to rotationally move in unison from an original position in which the first movable core 9 engages with the second movable core 11. Because the first movable core 9 and the second movable core 11 stick together before unlocking the shift lever, it is possible to avoid the first movable core 9 from hitting the second movable core 11 so as to eliminate an operational noise which would otherwise be produced by hitting the first movable core 9 against the second movable core 11. A lock plate 7 and a link plate 8 are rotatably provided around a rotational center 6 in relative to the solenoidal coil 10. This prevents the lock plate 7 and the link plate 8 from moving rotationally in unison with the solenoidal coil 10, thus enabling the lock plate 7 and the link plate 8 to a smooth and quick rotational movement.
