CONSTITUTION: This angular velocity sensor includes a liquid inactive mass 1, preferably mercury, capable of rotating relative to a container in which it is enclosed. a magnetic field passing the inactive mass 1, and a pair of electrodes 4, 2, with the inactive mass 1 formed into a sphere so that one 4 of each pair of electrodes between which voltage is measured is located at the center of the sphere to make the direction of the magnetic field invariable in space. | ||||||
| 8 | Angular acceleration sensor | JP10478682 | 1982-06-18 | JPS58221171A | 1983-12-22 | SUGIMOTO HIROSHI |
| PURPOSE:To obtain an angular acceleration sensor having excellent reliability and durability, by filling liquid in the liquid filling hole of a plane annular ring partitioned with a cross section and detecting the relative differential pressure exerted on the other side with respect to the pressure exerted on one side part thereof. CONSTITUTION:Now when a vehicle makes angular accelerative movement while curving left, and the inertia force proportional to the magnitude of the angular acceleration acts on the liquid 2 filled in a liquid filling hole 3. Therefore, the pressure exerted on the right side part of the hole 3 with a partition plate 4 as a boundary increases by as much as the pressure conforming to the magnitude of the angular acceleration than the pressure exerted on the left side part, thereby generating a relative difference in pressure. The relative differential pressure is detected as an electrical signal by pressure sensors 5, 5, and the angular acceleration of the vehicle is detected in a detection part 9 for the angular acceleration. The angular speed sensor having excellent reliability and durability is thus obtd. as there are no disturbance by the terrestrial magnetism or the like and no mechanical moving parts. | ||||||

| This invention relates to high precision, fluid-containing, transducer-based accelerometers that are capable of measuring acceleration, inclination, position and velocity by measuring the electronic response of a transducer to fluid flow caused by external acceleration or by free convection. The accelerometers of this invention are capable of varying the local density of the fluid, thereby creating a volume of fluid with a lower or higher density compared to the rest of the fluid in the accelerometer. The movement of this volume of lower or higher density fluid as a result of external acceleration is measured to determine the external acceleration. | ||||||

| An optical transducer comprises a light source for emitting radiant energy, a base member, and an elongate light collector positioned for receiving radiant energy from the light source. The elongate light collector comprises a tunnel formed in the base member and a collector window that extends along a length of the tunnel. Radiant energy projected by the light source is received in the tunnel through the window and is transmitted along a length of the tunnel. A portion of the transmitted radiant energy exits the tunnel to thereby vary the intensity of light along the tunnel length. At least one photosensor is positioned for detecting the amount of radiant energy at a location in the tunnel. In this manner, the intensity of radiant energy at the tunnel location is indicative of at least relative position between the incident radiant energy and the at least one photosensor. | ||||||
