Abstracts of our patents include:

US6246469: Sensing Apparatus

An apparatus for determining various physical quantities such as temperature, pressure, stress, strain, distance and the like in a manner such that a change in the physical quantity of interest result in a measurable change in the frequency of oscillation of a signal generated within the apparatus.

US5012049: Position Determining Apparatus

An apparatus for precisely locating the position of a transmitter either along a line or a surface or within a three dimensional space. More particular the apparatus of the invention is adapted for use of a computer and includes a pen sized moveable transmitter, or mouse, whose exact position can be determined without any use of physical connection between the transmitter and the balance of the apparatus.

US5764161: Sensing Apparatus Using Frequency Change

An apparatus and method for determining various physical quantities such as temperature, pressure, stress, strain, distance and the like in a manner such that a change in the physical quantity of interest results in a measurable change in the frequency of oscillation of a signal generated within the apparatus.

US4932270: Torque Sensor Having a Spoked Sensor Element Support Structure

Piezoelectric sensor devices are attached across pairs of circularly arranged spokes arrayed on the periphery of an annular ring. The sensor devices each include a preloaded steel ball mounting arrangement for mounting a piezoelectric sensor element. A first circular interface plate on one side of the sensor structure attaches to alternate ones of the spokes, and a circular interface plate attaches to the remaining spokes.

US4885433: Position Determining Apparatus

An apparatus for precisely locating the position of a transmitter within either a plane or within a three dimensional space. More particular the apparatus of the invention is adapted for use with a computer and includes a pen-sized moveable transmitter, or mouse, whose exact position within a plane or three dimensional space can be determined without the use of any physical connection between the transmitter and the rest of the apparatus.

US5590059: Position Encoder System Which Utilizes the Fundamental Frequency of a Ruled Scale on an Object

A position encoder system is disclosed for determining the position of an object. The system includes a camera, a ruled scale, and a control system. The system first obtains a pixel brightness image of the ruled scale attached to the object and downloads this data image to a computer. The computer, running a fast position determination, determines the fundamental frequency of the image through the use of a Fourier transform of the pixel brightness variations in the image. The phase difference between the fundamental frequency and a reference is then converted into an actual position of the object since the spacing of the individual rulings on the scale is known and one cycle of the fundamental frequency corresponds to one spacing interval on the rulings. With this measurement of the actual position, the control system compares it to the desired position and, if necessary, corrects the position of the object.

US55635917: Sensing Apparatus

An apparatus for determining various physical quantities such as temperature, pressure, stress, strain, distance and the like in a manner such that a change in the physical quantity of interest results in a measurable change in the frequency of oscillation of a signal generated within the apparatus.

US5026008: Fluid-Loop Reaction System

An improved fluid actuating system for imparting motion to a body such as spacecraft is disclosed. The fluid actuating system consists of a fluid mass that may be controllably accelerated through at least one fluid path whereby an opposite acceleration is experienced by the spacecraft. For full control of the spacecraft's orientation, the system would include a plurality of fluid paths. The fluid paths may be circular or irregular, and the fluid paths may be located on the interior or exterior of the spacecraft.

US4682508: Inlet Valve for Probe Apparatus

A valve assembly for allowing entry of a sampling device or probe device from an ambient atmosphere to a vacuum chamber comprises an electromagnet means which controls a ball made of magnetic material. Upon entry of the device into an entry inlet of the apparatus, the ball is seated in response to activation of the electromagnet means so as to seal an aperture leading to the vacuum chamber. As the device is moved toward the vacuum chamber, the magnetic force is removed. This allows the ball to drop away from the aperture allowing entry of the device into the vacuum chamber. Upon withdrawal of the device from the vacuum chamber, the ball is actuated by the electromagnet to seal the aperture, thereby maintaining the integrity of the vacuum system.
