| 21 | Apparatus for visually indicating the travel route of an automotive vehicle | US385671 | 1982-06-07 | US4531123A | 1985-07-23 | Katsutoshi Tagami; Tsuneo Takahashi; Shinichiro Yasui; Akira Ichikawa |
| An apparatus for use in an automotive vehicle for visually indicating the travel route thereof. A current travel route of the vehicle is arithmetically obtained in terms of two-dimensional coordinates for a unit travel distance of the vehicle on the basis of outputs from a travel distance detecting unit and a gas rate sensor. The thus-obtained locational data on the current location of the vehicle, varying from time to time, is stored in sequence, and the current travel path of the vehicle is continuously visually indicated. A timer unit is provided for starting the supply of power to the gas rate sensor a sufficient amount of time prior to starting the vehicle to permit the sensor to reach a stable working temperature in advance. | ||||||

| A heating wire is wound around a casing within which a sensor body is placed. Thermo-sensitive switch means is connected to the heating wire, which is responsive to the temperature within the casing to control the rate at which electric current is supplied to the heating wire so as to keep the temperature at a constant value. The casing may be placed within an airtight housing which is made of an insulating material. A further heating wire may be arranged on the inner wall of the airtight housing, which is controlled by further thermo-sensitive switch means so as to keep the temperature within the housing at a constant value. | ||||||

| 26 | Temperature stabilized fluidic angular rate sensor | US655345 | 1976-02-05 | US4020699A | 1977-05-03 | Max A. Schaffer |
| The measurement bridge of a fluidic angular rate sensor in which a pair of temperature sensitive resistive elements are differentially cooled by a jet of fluid, the direction of which lags the position of the resistive elements when the rate sensor is rotated in the plane of sensitivity, is driven by a constant voltage source through resistances substantially equal to the rate sensing resistive elements so that as the resistive elements increase in resistance with temperature, the voltage also increases, so the power consumption and therefore the heat generated in the resistive elements remains constant, thereby tending to maintain a constant temperature differential of the resistive elements above the ambient, and in turn reducing changes in thermally-induced mechanical stress and resulting motion; further, lack of tracking between the two resistive sensing elements over wide temperature ranges is compensated by coupling some of the resultant temperature-dependent voltage to a bridge node to compensate for the temperature-dependent mismatch, said voltage being nulled at normal temperature by coupling of fixed voltage of opposite polarity to the same node. | ||||||
| 27 | Method for measuring a rotational velocity and a gyrometer for the practical application of said method | US39441573 | 1973-09-05 | US3909706A | 1975-09-30 | GRESCINI JEAN; GLENAT HENRI; SALVI ANTEINE |
| A homogeneous and steady directing magnetic field is produced in the direction about which a rotational velocity is to be measured. An electrical signal is delivered by a nuclear magnetic resonance magnetometer probe which is placed in the magnetic field and rotates at said velocity. The difference between the frequency of the signal and the detected frequency of resonance or reference frequency serves to determine the value of rotational velocity.

| Golf performance and equipment characteristics may be determined by analyzing the impact between a golf ball and an impacting surface. In some examples, the impacting surface may be a golf club face. The impact between the golf ball and the surface may be measured based on sound and/or motion sensors (e.g., gyroscopes, accelerometers, etc.). Based on motion and/or sound data, various equipment-related information including golf ball compression, club head speed and impact location may be derived. Such information and/or other types of data may be conveyed to a user to help improve performance, aid in selecting golf equipment and/or to insure quality of golfing products. | ||||||

| Angular rate sensors cause a stream of fluid to flow by heating the fluid. A trajectory of the stream of fluid is deflected by Coriolis forces. Apparatus according to some embodiments provides two heaters spaced apart along a channel. A stream of gas can be made to flow along the channel by operating one of the heaters. The flow can be periodically reversed by alternating operation of the heaters. Temperature sensors may be applied to detect deflection of the flowing gas. Angular rate sensors may be fabricated inexpensively by micromachining techniques. | ||||||

The composite is heated after bonding, for up to 200 hours to a temperature of from 250.degree. C. to Tg-10 K. As a result of this heating, controlled compaction of the glass body and, hence, bending of the composite, are achieved to reduce or reverse any distortion that has occurred during bonding. | ||||||
| 40 | Surface jet angular rate sensor | US410855 | 1995-03-27 | US5780738A | 1998-07-14 | Steven E. Saunders |
| An apparatus for sensing an angular rate of motion includes a body which defines a surface having a protuberant portion, and an orifice through the surface and proximate to the protuberant portion through which a fluid jet is directed along an initial jet axis. The protuberant portion directs the fluid jet in a path along the surface in accordance with the Coanda effect. A first flow sensor is fixed relative to the body and proximate to the path of the fluid jet along the surface of the body. The first flow sensor produces a first indication of a rate of flow of a first portion of the fluid jet proximate thereto. A second flow sensor is fixed relative to the body and proximate to the path of the fluid jet along the surface of the body. The second flow sensor produces a second indication of a rate of flow of a second portion of the fluid jet proximate thereto. The angular rate of motion of the body is sensed in dependence upon the first indication and the second indication. | ||||||
