Patent number: 5831260Abstract: A hybrid motion tracker captures the motion of a person. Magnetic field sensors and optical sources are placed on a person, each located on different limbs. A fixed transmitter emits electromagnetic energy and infrared light is transmitted from the optical light sources to the fixed optical sensors. The magnetic field sensors sense the magnetic field and a computer calculates each sensor's position and orientation relative to the fixed transmitter. The optical system's Position Sensing Detectors measure the transmitted infrared light and the computer calculates the position and orientation of each optical light source. The position and orientation of each sensor is used to reconstruct the person's motion in real time, which is sent to a host computer. The computer utilizes the optical system which is more precise than the magnetic field system to compensate for the magnetic field system and thereby achieve higher accuracies. The system is a hybrid system using both magnetic fields and infrared light.Type: GrantFiled: September 10, 1996Date of Patent: November 3, 1998Assignee: Ascension Technology CorporationInventor: Per Krogh Hansen

Patent number: 5827956Abstract: A measuring wheel detects forces and moments between the rim and axle of a vehicle wheel with measuring sensors between the rim face and a wheel flange apparatus transmits the energy and data to a measurement evaluation and processing system on the vehicle. The wheel flange and/or the front of the rim consists of a fiber compound, while the apparatus on the wheel for transmitting energy and data are fitted on the inside of the rim bed holding the vehicle tire and extends essentially over its circumference. Thus the static properties and dynamic behavior of the measuring wheel during travel correspond to the greatest degree to the original wheel. Effects which falsify the measurements such as increased wheel weight and the like do not arise.Type: GrantFiled: October 10, 1995Date of Patent: October 27, 1998Assignee: Audi AGInventors: Andreas Beste, Josef Vogler, Frank Hailer, Manfred Muller, Werner Aicher

Patent number: 5824910Abstract: An improved hydrostat constructed on a silicon wafer by microfabrication methods similar to those used for integrated circuits and other devices. A thin section of the wafer acts as a diaphragm, responsive to pressure of ambient water. A lever arm is affixed at its first end to one point on the surface of the wafer and extends over the diaphragm, so arranged that the lever arm will be forced away from the wafer when pressure is applied to the diaphragm. The second end of the lever arm is moved by the diaphragm so that it moves further from the wafer, by a factor of the mechanical advantage of the lever. When the second end moves away from the wafer, it mechanically releases a lock, allowing an ordnance device to which the hydrostat is attached to arm.Type: GrantFiled: April 16, 1997Date of Patent: October 20, 1998Assignee: The United States of America as represented by the Secretary of the NavyInventors: Howard R.

Patent number: 5825326Abstract: A GPS system and method for real-time determination of integer ambiguities in a global positioning system (GPS) receiver and, more specifically, to a GPS system and method for determining integer ambiguities of a GPS solution using a Kalman filter with double difference integer ambiguities as additional states to estimate the ambiguities until they are estimated to within a sufficiently tight variance around their error estimates. Thereafter, all the candidate integer ambiguity values are searched in the range domain, e.g., along the double difference lines-of-sight for each satellite, until one is selected; if the after-the-fit residuals for the selected integers are below a certain threshold, then the selected integers are accepted as the integer ambiguities. If not, another set of candidate integer values are selected and analyzed.Type: GrantFiled: July 9, 1996Date of Patent: October 20, 1998Assignee: Interstate Electronics CorporationInventors: James Russell Semler, Earl Clare Thorndyke, Jr.
