| A device for determining the rotational speed of an object (10) adapted to rotate about a predetermined rotation axis (12). The device is particularly useful as a servo control for motors, such as motors having optical tachometers, tone wheels and for brushless DC motors in which the commutation Hall sensors (16) are being used in lieu of a tachometer. Sensor and other positional errors are substantially eliminated by sensing the time intervals between at least two rotational positions of the rotor through a full rotation of the rotor, and averaging the time intervals of each time measurement between succeeding rotor positions over the prior revolution of the rotor. The average is compared to a preset value representative of the desired speed, and the current applied to the servo control circuit is adjusted, if necessary, in order to increase or decrease the speed of the rotor to the desired speed. | ||||||

| 105 | Apparatus for measuring flowing gas or air stream parameters | EP82300215 | 1982-01-15 | EP0057069A3 | 1982-08-11 | Nuspl, Steven Paul |
A device which can determine either the velocity pressure or the velocity of a flowing gas or air stream and average same over a predetermined period of time is disclosed. The device utilizes a three-hole yaw probe or similar sensing means which is immersed in the stream to provide measurements of both static pressure differential and velocity pressure. The device includes a null threshold detector (14) which permits the processing of velocity pressure measurements only when the static pressure differential is within a pre-set range thus ensuring the proper alignment of the probe or other sensing means in the stream. A square root extractor (20) and switching means (22) are also provided permitting the measurement and averaging of the square root of the velocity pressure measurement, i.e., velocity of the stream, by the device. The velocity pressure measurements or the square root thereof are exhibited on a first digital display (28) permitting the operator to monitor the measurements as they are taken. The measurements are subsequently averaged over a predetermined period of time by an arithmetic processor (18) and the resulting average is exhibited on a second digital display (30). |

| An article and method are described that measure the average speed of an object. A timer measures the time an object takes to travel from a start to a finish. A goniometer measures the angle between the start, the article, and the finish. A wave generator determines the distances from the article to the start and finish. Using a geometric identity, the distance traveled by the object from the start to the finish can be determined and, using the time, the average speed can be calculated. The article and method are especially suitable for quickly measuring the average speed of objects moving below about 10 m/s and without defining a predetermined path. An electronic processor can be used to automate the method. | ||||||

The sensor includes a tubular housing which extends across the interior of the conduit. An electromagnet is arranged in the housing and produces an electromagnetic field in the fluid, the axis of the field extending normal to the direction of fluid flow. A plurality of electrodes are arranged in spaced relation along the length of the housing and in diametrically opposed pairs on opposite sides of the housing.
