摘要： An acceleration-sensing system for sensing acceleration in a three-dimensional manner is proposed. The acceleration-sensing system includes a first acceleration-sensing unit for sensing acceleration in a two-dimensional manner along first and second directions that are perpendicular to each other and a second acceleration-sensing unit for sensing acceleration in a one-dimensional manner along at least another direction that is perpendicular to the first and second directions.

摘要： A ferrofluidic electromagnetic power generator installed within a rotating object, such as the interior of a vehicular tire generates electric current in an electrical coil wound about an elongated, hermetically sealed housing made of non-magnetic material, partially filled with magnetized ferrofluid. A permanent magnet and two magnetic pole pieces enclosing the housing and the coil in conjunction with the ferrofluid form a magnetic circuit. Rotation and horizontal velocity of the tire will propel the magnetized ferrofluid within the sealed housing causing induction in the electrical coil.

摘要： A ferrofluidic electromagnetic power supply firmly attached to an agitating object, such as the interior of a vehicular tire generates electric current in an electrical coil deposited between and firmly attached to an hermetically sealed housing made of non-magnetic material partially filled with ferrofluid and a permanent magnet axially polarized. The ferrofluid and the permanent magnet form a magnetic circuit extending from the ferrofluid through the coil to the permanent magnet and back to the ferrofluid. Agitation of the power supply will cause dislocation of the magnetized ferrofluid within the sealed housing causing induction in the electrical coil.

摘要： An inductive rotational accelerometer for assisting in servo control of a hard disc drive using a torsional mass-spring system in combination with an inductance sensitive circuit to detect and measure the rotational vibrations imposed on a hard disc drive. The inductive rotational accelerometer includes a frame member coupled to the disc drive, the frame member supporting a pin on which is disposed a rotational mass. The rotational mass supports conductive blocks which with the rotational mass and the frame member provide a path for inductance.
