Abstract: A multi-function electronic compass incorporates multiple sensors in addition to magnetometers inputting sensed data to a microprocessor system which calculates a variety of results from the sensed data in addition to direction. Direction indicia and other results are output for a user on a display. Additional sensors include one or more of an inclinometer, an altimeter, an accelerometer, and a barometer. In one aspect the compass has a tilt-up lid with a sighting port and an adjacent mirror, and the microprocessor system displays directional indicia backwards so the reflected indicia in the mirror adjacent to the sighting port are directly readable by the user using the sighting port. In one model a laser beam is included as an aid in sighting.

Abstract: A magnetic field sensor element comprises an elongated core of high-magnetic permeability material having a coil of electrically-conductive wire wound around and along a central axis of the core. The sensor, due to inductance of the core which changes with application of a local magnetic field, exhibits a characteristic of delaying an electrical input as a function of the strength of a magnetic field in the direction of the axis of the core, and the delay is measured as a function of the strength of the magnetic field. Appropriate circuitry provides at least one step-function voltage input to the coil such that the resulting delay in current charge-up into the coil creates a voltage across the coil which decays to a known reference value. The time delay for the voltage decaying to the reference value varies as a monotonic function with the strength of the applied magnetic field to be measured.

Abstract: A process and apparatus for thermally decomposing silicon containing gas for deposition on fluidized nucleating silicon seed particles is disclosed.Silicon seed particles are produced in a secondary fluidized reactor by thermal decomposition of a silicon containing gas. The thermally produced silicon seed particles are then introduced into a primary fluidized bed reactor to form a fludized bed. Silicon containing gas is introduced into the primary reactor where it is thermally decomposed and deposited on the fluidized silicon seed particles. Silicon seed particles having the desired amount of thermally decomposed silicon product thereon are removed from the primary fluidized reactor as ultra pure silicon product.An apparatus for carrying out this process is also disclosed.
