    • An inclination sensor includes: a case having a turning shaft section projected in a lateral direction on a front surface thereof; magnetism detecting means fixed on an upper side of the turning shaft section; a pair of magnets fixed in parallel to a rear surface of the case to be located on both sides of the magnetism detecting means; a pendulum axially supported by the turning shaft section to turn freely; and a pair of ferromagnetic bodies fixed on an inward surface of the pendulum. When the case inclines, one of the ferromagnetic bodies approaches the magnetism detecting means, and a magnetic circuit is closed by the pair of magnets and one of the ferromagnetic bodies. Magnetic fluxes of the magnets pass over front and rear surfaces of the magnetism detecting means.

    • A power tool (10) includes a levelling device (30) which includes a rotatable member (40) which seeks an equilibrium position which corresponds to a level position. A rotating device includes a member which enables passage of a beam. An electrical circuit which includes an emitting device (50), a receiving device (52) and an indicating device is electrically coupled such that upon activation, the emitting device (50) emits a beam which passes through the beam passing member. The beam is received by the receiving device (52) which, in turn, activates the indicator device (54). The indicator (54) is generally a light emitting device which has a varying brightness so that the user may view the indicator (54) from all sides of the power tool (10).

    • Tilt and vibration sensor and method for forming the sensor with a piezoresistive membrane (10) having a weight (16) affixed proximate its center for detecting the tilt and vibration of a body. The membrane (10) may include four piezoresistors (12, 14) placed proximate the edges (20, 22) of the membrane (10) at the points of maximum stress when the membrane (10) is subject to a uniform applied pressure. The piezoresistors (12, 14) may form a Wheatstone bridge circuit to generate a first (34) and second output voltage (36) in response to changes in resistance of the piezoresistors (12, 14) under the uniform applied pressure. The first output voltage (34) may be indicative of the angle of inclination of a body and the second output voltage (36) may be indicative of the vibration of the body. The membrane (10) may be fabricated from a silicon wafer using known photolithography and etching processes. The membrane (10) maybe connected with a voltage source and secured within an appropriate housing to be placed in an operational environment.
