| A rate measuring instrument uses acoustic energy transmitted through a crystalline media (41) to sense rate. Acoustic energy travels along a path (1-31) within the crystalline media and impinges upon an output transducer (45) at an established point after being reflected a number of times from facets (47) of the crystalline media (41). Rate information is detected as a shift in the point of impingement of the greatest amount of acoustic energy upon the output transducer (45). | ||||||

| A device for detecting displacements of a fluid jet is disclosed. The device is particularly suitable for use as part of a fluidic angular rate sensor. The device comprises a wire resistor suspended between a pair of metal posts, a means for producing a magnetic field at the location of the resistor, an alternating current (AC) source electrically connected across the resistor for heating the resistor and for interacting with the magnetic field to cause the resistor to oscillate, and readout electronics for sensing changes in wire resistance which are a function of wire temperature variations associated with fluid jet displacements. The use of a single oscillatory wire resistor eliminates the need for the difficult to achieve and costly wire matching procedures of conventional two wire fluid jet displacement detectors. | ||||||

| An angular rate of change sensing device of the type wherein angular rate of change, movement, or velocity is indicated by sensing a differential fluid velocity relative to a sensing apparatus in an underdeveloped laminar fluid flow field and is characterized primarily in that under conditions of no angular movement, there exists a constant or flat fluid velocity and density profile in a plane normal to the longitudinal axis of the flow channel. The device consists of a fluid flow inlet conditioner, a contoured inlet nozzle, a straight or slightly diffusing flow channel, a flow sensing apparatus inside the channel, and a device for pumping fluid through the flow conditioner and channel. Under conditions of angular rotation the velocity profile of a constant velocity, laminar fluid flow field relative to a sensing apparatus, is distorted due to fluid dynamic inertial effects and due to the effects of a relative velocity differential between sensing elements. Sensing apparatus positioned inside the fluid flow channel responds to a differential fluid velocity and yields output signals proportional to an induced angular movement in a plane which includes the differential sensors and the longitudinal axis of the flow channel. | ||||||

| PURPOSE: Disclosed is a magneto hydrodynamic sensor having an annular sense channel containing a conductive liquid proof mass. CONSTITUTION: The sensor includes an annular sense channel containing a conductive liquid proof mass (11, 12). A radial flow is introduced into an annular channel (14) which, in response to rotation of the device, produces a coriolis force and resulting circumferential velocity of the fluid. An electromagnetic winding produces an alternating electromagnetic field directed perpendicular to the annular channel. First and second electrodes (17, 18) sense a time varying electric potential induced between the center of the annular channel and the circumference of the annular channel. The time varying electrical potential is proportional to the strength of the time varying electric field and rotational velocity of the channel with respect to the proof mass. The transformer (23) connected to the electrodes provides for amplification of the signal representing the rotational velocity of the channel with respect to the proof mass. | ||||||

| A process is disclosed for bending in a determined manner anodically bonded flat composite bodies made of glass and metal or semiconductor materials. After bonding, the composite body is heated for 200 hours up to a temperature from 250 °C to Tg-10 K. Heating causes the glass body to shrink to a determined extent and the composite body to bend. Warp caused during bonding may thus be undone. | ||||||
| 100 | LOW FREQUENCY ANGULAR VELOCITY SENSOR | EP92901295.3 | 1991-11-22 | EP0560880B1 | 1997-04-09 | LAUGHLIN, Darren, R. |
| A magnetohydrodynamic angular rate sensor is described. A housing (30) supports first and second fluid proof masses in respective coaxial annular channels (11, 17), permitting relative motion between the proof masses and the housing. First and second magnets (12, 18) associated with each annular channel (11, 17) result in an electric potential being generated across each channel proportional to the relative circumferential velocity between the proof masses and the housing. The annular channels are connected together to form a continuous pumped fluid circuit which introduces a radial flow velocity in each channel. At low rotational frequencies, a circumferential velocity component is induced in the proof masses due to Coriolis acceleration which results in a measurable electrical voltage across the annual channels. The low frequency response of the sensor is therefor extended to lower frequencies. | ||||||
