| The invention detects the loft time and/or speed of a vehicle, such as a sporting vehicle, during activities of moving and jumping. A loft sensor detects when the vehicle leaves the ground and when the vehicle returns to the ground. A microprocessor subsystem converts the sensed information to determine a loft time. A display shows the recorded loft time to a user of the system. In addition, a speed sensor can detect the vehicle's speed for selective display to the user. The invention is particularly well-suited to sporting activities such as snowboarding where users loft into the air on ski jumps and catch nullairnull time but have no quantitative measure of the actual time lapse in the air. Therefore, users in skiing can use invention to record, store, and playback selected information relating to their sporting day, including the total amount of nullairnull time for the day and information such as dead time, i.e., time not spent on the slopes. | ||||||
| 88 | Process and a device for the rotation-angle-monitored tightening or loosening of screw connections | US171712 | 1993-12-21 | US5476014A | 1995-12-19 | Markus Lampe; Torsten Schmidt; Edgar von Hinueber |
| The invention relates to a process and a device for the rotation-angle-monitored tightening or loosening of screw connections by means of power driven tools. The absolute rotation angle swept over in the screwing operation with respect to a fixed point about a swivel axis through the rotation axis of the screw connection is measured. An advantageous, relative-position free, absolute measurement of the rotation angle is effected by the use of an absolute rotation-rate measuring sensor. The rotation-rate sensor can herein be configured as a mechanical, compass-like gyroscope, as a rotation sensor or as an acceleration sensor, by means of which a measured value correlated with the absolute rotation angle can be recorded. | ||||||
| 89 | Method for reverberation suppression | US101949 | 1993-08-04 | US5365492A | 1994-11-15 | William H. Dragoset, Jr. |
| A method for reducing the effects of reverberation on noisy seismic wavefields recorded from within a moisture-laden environment. The wavefield manifests itself as a pressure signature and a velocity signature that contains an embedded nose signature. The pressure signature is adaptively filtered and subtractively combined with the velocity signature to isolate a nearly pure noise signature. The nearly pure noise signature is added back to the original velocity signature with opposite sign to clear away the embedded noise, leaving a refined velocity signature. The refined velocity signature iteratively is scaled and summed with the pressure signature, incrementing the scale factor at each iteration and autocorrelating the sum. A coefficient of convergence is calculated after each summation. The coefficient of convergence that most closely approaches unity identifies the preferred scale factor. | ||||||
| 90 | Tachometer noise reduction system using a pickup coil to cancel the noise from the tachometer signal | US396581 | 1989-08-21 | US5045784A | 1991-09-03 | Frank A. Pizzarello; Clifford D. Dax |
| A current carrying drive coil in a magnetic field is moved by the field. An attached tachometer coil, passing through the same field, produces a voltage from which the speed of the coils may be calculated. Changes in the drive coil current produce noise in the tachometer coil. This noise is offset by combining the tachometer voltage with the voltage produced by a stationary pickup coil, which picks up only the noise. | ||||||
| 91 | System for determining the movement of a track vehicle | US133001 | 1987-12-15 | US4815319A | 1989-03-28 | Gilles Clement; Jean-Marie Detriche; Eric Villedieu |
| A system determines the movement of a track vehicle along the ground, the track vehicle having at least a first rotatable, endless track for supporting the vehicle on the ground, a drive for causing the movement of the vehicle, and a turning system for changing the direction of the movement of the vehicle. The system has a first traction-improvement device for mounting on the track vehicle. It bears on an inner-surface side of the first track with sufficient pressure for a small-surface portion on the opposite side of the first track to engage the ground with a higher pressure than any other portion of the first track, whereby to locate a pivoting axis of the track vehicle in the vicinity thereof. A first speed sensor for mounting on the track vehicle in the vicinity of the small-surface portion on the opposite side of the first track senses the speed of movement of the track vehicle along the ground only in the direction of the rotation of the first track and provides a first information thereof, whereby the movement of the track vehicle may be deduced therefrom. Preferably the vehicle has two tracks, and the system has two such traction-improvement devices and speed sensors respectively for the two tracks. | ||||||
| 92 | Resonant vibrating structures with driving sensing means for noncontacting position and pick up sensing | US7033 | 1987-01-27 | US4806859A | 1989-02-21 | Robert E. Hetrick |
| A vibration type sensor can make a noncontacting measurement of position or pick up the passage of an object past a point. The sensor has a coil of wire placed on a vibrating structure. As an object with an attached magnet approaches the coil, an emf is induced in the coil indicating position. Alternatively, the magnet remains fixed with respect to the vibrating coil while a material of high magnetic permeability approaches the coil and magnet combination thereby perturbing the magnetic field and changing the induced emf. This method can be used to obtain a linear variation of sensor output with position or to enable the use of the device as a pickup sensor. | ||||||
| 93 | Apparatus and method for measuring the speed of a movable system with respect to a data carrier | US186295 | 1980-09-11 | US4379256A | 1983-04-05 | Christian Maury |
| The relative speed of a movable head and a magnetic disc memory for data orded on a plurality of tracks, each having addresses written in a plurality of reference zones, is determined by reading the addresses read with the head at predetermined sampling times. The speed of the head is calculated as a function of the difference between the addresses read by the head and the interval between the sampling times. | ||||||
| 94 | Tachometer system | US883131 | 1978-03-03 | US4216419A | 1980-08-05 | Rudolf A. A. F. van Dam; Kornelis A. Immink |
| A tachometer system for supplying a control signal indicative of positional and/or speed errors of a rotatable element comprises a tachometer on which marks are arranged in a closed track and a detector responsive thereto to produce n tacho-pulses per revolution of the tachometer. The tachometer system further comprises a memory device with n locations in which n correction signals are stored. The correction signals are obtained by driving the tachometer at an accurately constant speed, measuring the phase difference between the tacho-pulses and the reference signal, and storing the phase-error signals related to the consecutive tacho-pulses in separate locations of the memory device. When the tachometer system is used in a servo control loop these correction signals are used to correct the phase-error signals then measured, yielding a correction in respect of the deviations in these phase-error signals owing to positional tolerances of the marks on the tachometer. | ||||||

| 96 | Method and apparatus for attitude detection and stabilization of an airborne vehicle using the electrostatic field in the earth{3 s atmosphere | US30136372 | 1972-10-27 | US3868074A | 1975-02-25 | HILL MAYNARD L |
| A method and apparatus for utilizing the earth''s static electric field as a reference for generating an information-bearing electrical signal. In a particular embodiment, the invention provides a differential static voltmeter having spaced voltage sensing probes and a differential static amplifier which determines the difference in voltage sensed by the probes. Since the probes measure the static voltage which occurs as a vertically oriented gradient in the earth''s atmosphere, the voltage difference signal produced by the differential static amplifier is a measure of the disposition of the probes relative to a line usually parallel to the earth''s surface, the voltmeter thereby being particularly useful as a pitch and roll stabilization reference and control system for airborne vehicles. In other embodiments, the invention also provides apparatus for defining a horizontal reference plane in the atmosphere and apparatus for sensing the roll or pitch rate of an airborne vehicle.

| 97 | Device for measuring vehicle speed by measuring disturbance of the earth{3 s magnetic field | US43756574 | 1974-01-29 | US3860869A | 1975-01-14 | PARKS JACK G |
| The disclosure shows a vehicle speed measuring device using a magnetometer located a known distance from the vehicle path. Vehicle movement disturbs the earth''s magnetic field, and the vertical component of the response, measured by the magnetometer, is fed through electronic circuitry which measures the elapsed time between the maximum signal thus generated and half of the maximum and measures that time against the distance covered, computing the vehicle speed and registering the speed on a visual readout.

| 98 | Apparatus measuring relative velocity of movable members including means to detect velocity from the position encoder | US15728371 | 1971-06-28 | US3839665A | 1974-10-01 | GABOR A |
| A transducer coupled to a motor shaft provides both position and velocity information for use in a closed loop control system. The transducer includes a disk with deposited metallic parallel conductors each conductor carrying current in a direction opposite to the adjacent conductor. Relative movement of one disk with respect to another produces a position signal in a manner well known in the art. However, multiple windings are used to provide multiple position signals displaced in space phase which are then processed by differentiation and commutation to provide a velocity signal used as a control voltage in the control loop. A reference signal is also derived by commutation from the position signal.
