Abstract: A system that measures the motion of a camera traveling over a living subject by reference to images taken from the camera, while measuring the subject's shape, pose and motion. The system can segment each image into pixels containing the subject and pixels not containing the subject, and ascribe each pixel containing the subject to a precise location on the subject's body. In one embodiment, a computer connected to a camera and an Inertial Measurement Unit (IMU) provides estimates of the camera's location, attitude and velocity by integrating the motion of the camera with respect to features in the environment and on the surface of the subject, corrected for the motion of the subject. The system corrects accumulated errors in the integration of camera motion by recognizing the subject's body shape in the collected data.

Abstract: A system that measures the motion of a platform traveling over water by reference to images taken from the platform. In one embodiment, the invention is comprised of a computer connected to a camera and an Inertial Measurement Unit (IMU) which provides estimates of the platform's location, attitude and velocity by integrating the motion of the platform with respect to features on the water's surface, corrected for the motion of those features. The invention measures the motion of the water features according to equations of surface water wave celerity to measure motion of features across the water, and by measuring the feature motion shear across images or the discrepancy between the navigation estimates and the observed water feature motion to detect boundaries of water currents. The invention is also capable of measuring water depth, wave motion, sea state and current present in the water, whether affixed to a navigating platform or to a stationary reference point.

Abstract: A system for ensuring Automatic Dependent Surveillance—Broadcast (ADS-B) integrity of an aircraft includes a designated aircraft interrogation area, an ADS-B receiver, and an alerting mechanism. The ADS-B receiver is configured to receive ADS-B data from the aircraft when the aircraft is located in the designated area and to send a signal to the alerting mechanism indicating that the aircraft is in the designated area.

Abstract: Small, hermetically sealed pans are leak tested after subjecting the finished device to an environment of trace gas such as helium. During the testing process the pans may lose their helium charge by rapid escape due to massive gross leaks. These cases demand pre-helium mass spectrometer leak detector gross leak testing procedure. The non-helium expansion technique, used in conjunction with a helium mass spectrometer leak detector, provides a reliable and automatic gross and fine leak testing of the pans by a single apparatus. The test pan is placed in a sealed test fixture, and a valve between the test fixture and an expansion chamber is opened. The pressure in the expansion chamber is measured after the valve is opened. When the measured pressure is less than a reference pressure, a leaking test pan is indicated. When a sealed test pan is indicated, a helium mass spectrometer leak test is performed to determine the presence of fine leaks in the test part.

Abstract: A gyroscope is firmly held against the back side of the human hand to reduce or eliminate the effect of naturally occurring tremors such as essential tremor or other tremor. The gyroscope is driven by an electric motor energized by batteries. The batteries are mounted near the periphery of the gyroscope to enhance the gyroscopic action. In a modified form of the invention the motor is not mounted on the back side of the hand but is a separate unit to which the gyroscope can be readily coupled and uncoupled.

Abstract: A ferromagnetic element has current passed through it either by direct electrical connections or by induction. The current through the ferromagnetic element may be far greater than is necessary to heat the element above its effective Curie temperature. As the element is heated and is passing through its effective Curie transition (that is its temperature is rising from below its effective Curie temperature to, or above, its effective Curie temperature) the change in permeability of the element is sensed and the current through the element is cut off. The element then cools. When the temperature falls below the effective Curie temperature, the full current is restored. The heating and cooling process repeats itself indefinitely. The result is that the element is maintained at its effective Curie by a pulsating current fed to the element.
