Filed:

Nov 9, 1999

Appl. No.:

09/437290

Inventors:

Mark Anderson - Littleton CO 80127
Larry Meiners - Rapid City SD 57702

International Classification:

G06W 100

US Classification:

7317026

Abstract:

The present invention is an optical ice detection probe capable of detecting the presence, thickness and continued buildup of ice. The invention works by attaching the probe to the external surface of an airplane such as the wing, fuselage or empannage. The probe has a recessed surface, which is mounted to face directly into the airflow. One or more beams are passed over and parallel to the recessed surface. These beams can be of any useful wavelength, however for best results visible, infrared or ultraviolet beams should be used. Ice on the recessed surface interrupts the beams thereby indicating the presence of ice. If two or more beams are used, then each beam emitter is paired with a beam detector and the corresponding beam detector only detects the beam from that emitter. This can be accomplished by numerous methods. For example, powering each beam emitter alternately and sampling the output of the corresponding detector, electronically modulating the beam to a specific frequency with corresponding detectors designed to respond to the specific frequency or using an optical filter that passes only specific wavelengths.

International Classification:

G01W 100

US Classification:

7317026

Abstract:

An integrated air data probe capable of measuring pressure, temperature, relative humidity, turbulence, heading, air speed, the presence of ice, and other relevant measurements for use in building a real time map of the aircraft flying conditions. The probe is attached to the external surface of an airplane such as the wing, fuselage or empannage and is adapted to collect and relay these measurements to a receiving station. By utilizing these probes on numerous airplanes, real time data from numerous data points can be mapped to provide pilots and airlines complete information regarding flying conditions. Additionally, the probe includes a recessed surface for detecting the presence, thickness, and continued buildup of ice by mounting the recessed surface directly into the airflow. One or more light beams are passed over and parallel to the recessed surface, and if ice is present the beams are interrupted.

Appl. No.:

10/306032

Inventors:

Larry Gene Meiners - Rapid City SD

Assignee:

Phase Technologies, LLC. - Rapid City SD

International Classification:

H02M 112

US Classification:

363148, 363149, 363 38, 363 39, 363 40

Abstract:

A phase converter that converts single phase AC electric power to balanced three phase AC power. Two input terminals are connectable to a single phase AC power source, and connect directly to two output terminals of the converter. The phase converter has a storage capacitor, a charging circuit for controlled charging the storage capacitor and an output circuit for controlled discharge of the storage capacitor to provide single phase AC power to a third output terminal. The charging circuit controls input to the storage capacitor to provide a sinusoidal input current and to step up the voltage to the storage capacitor. The output circuit provides output power to the third output terminal of a predetermined phase and amplitude, relative to the other two output terminals, to result in balanced three phase AC power at the three output terminals.

US Classification:

363 36

Abstract:

A phase converter that converts single phase AC electric power to balanced three phase AC power. Two input terminal connected to the output of a single phase AC power source connect directly to two output terminals of the converter. The phase converter has two serially connected storage capacitors with a common connection, a charging circuit for controlled charging the storage capacitors and an output circuit for controlled discharge of the storage capacitors to provide single phase AC power to a third output terminal. The charging circuit controls input to the storage capacitor to provide a sinusoidal input current and to step up the voltage to the storage capacitors. The output circuit provides output power to the third output terminal of a predetermined phase and amplitude, relative to the other two output terminals, to result in balanced three phase AC power at the three output terminals. The phase converter provides balanced three phase output for leading power factor, lagging power factor, and resistive loads.

International Classification:

H01L 2978

US Classification:

357 23

Abstract:

An improved normally off insulated gate field-effect transistor capable of peration at frequencies in excess of 1 GHz wherein the substrate is a semi-insulating semiconductor. The substrate may be Fe or Cr doped InP or Fe or Cr-doped GaAs. Contacts for the source and drain electrodes are realized by forming n. sup. + contacts for the n-channel device and p. sup. + contacts for the p-channel device. Au-Sn will form n. sup. + contacts while Au-Zn will form p. sup. + contacts.
