摘要： A method is disclosed for measuring the linear velocity of recording of data recorded a CD using a Hall sensor. A Hall sensor is placed in the spindle motor of a CD drive to produce a signal based on alternating magnetic flux in the spindle motor. An amplified and processed version of the signal output from the Hall sensor during operation of the CD drive is monitored to measure the timing of three successive inversions of the signal. Based on this timing measurement, the rotational speed of the spindle motor is determined. The recording linear velocity of the data recorded on the CD presently mounted in the CD drive is obtained based on the rotational speed determined from the Hall signal and on a reference rotational speed. As a result of using this method for obtaining the recording linear velocity of the data recorded on the CD, no errors are generated based on the number of tracks the pickup is moved across, and the time necessary for measuring the recording linear velocity is reduced.

摘要： The method of the present invention utilizes a microcomputer in combination with a CRT and a multiplicity of transducers for monitoring process parameters in the operation of a reciprocating device having a linear stroke. A profile of the process parameters including pressure and velocity are generated as a function of stroke length and time and are stored in a non-volatile memory and graphically displayed on the CRT as master traces for comparison with current data profiles. The velocity is calculated by dividing distance transversed with time or by use of a velocity position transducer.

摘要： A method of forming a tachometer roller for a tape drive assembly for detecting the speed of a tape moving along a reference axis when the tape is in contact with the roller. The roller includes a cylinder extending in a longitudinal axis and adapted to be fixed in a tape drive assembly for rotation along the reference axis. The periphery of the cylinder defines an air vent groove running obliquely to the longitudinal axis for venting of air captured between the periphery and the tape. The vent groove terminates in respective circumferential grooves formed in respective edge portions of the roller. The vent groove is formed from a single plunge cut of a tool starting at a first circumferential groove and terminating at the other circumferential groove.

摘要： A combined log and speedometer having a digital readout is provided wherein an electronic speed sensor actuates a voltage controlled oscillator so that the frequency of the oscillator is proportional to speed. The output pulses are counted and accumulated to give an indication of the distance traveled and simultaneously the output pulses are sampled for precise periods of time to give an indication of speed. Both speed and distance are displayed digitally.

摘要： A method of recognizing obstacles on operation of a vibratory pile driver of a work machine includes monitoring an acceleration signal of the vibratory pile driver during operation of the vibratory pile operator and analyzing the acceleration signal to determine the presence of an obstacle. The acceleration signal may be monitored over a time period which is determined based on an excitation frequency of the vibratory pile driver. The analysis may include comparing negative and positive half-waves of the acceleration signal. Responsive to the analysis indicating an obstacle, a system operator may be alerted, and/or operation of the vibratory pile driver may be adjusted via controller intervention.

摘要： A speed sensor for detecting a speed of a magnetizable object. The speed sensor (100) can be supplied with an electric alternating signal with a first frequency by an electric signal source. The speed sensor including: a primary coil for generating a magnetic alternating field with the first frequency; first and second secondary coils. The first and second secondary coils can each be magnetically coupled to the primary coil via a magnetizable object. First and second electric signals induced in the first and second secondary coils respectively by the generated magnetic alternating field; a Goertzel filter bank detects first and second amplitude values of respective spectral components of the induced first and second electric signals in the event of a second frequency which differs from the first frequency. A processor determines the speed of the magnetizable object depending on the detected first amplitude value and the detected second amplitude value.

摘要： The present invention discloses a magnetoresistive gear tooth sensor, which includes a magnetoresistive sensor chip and a permanent magnet. The magnetic sensor chip is comprised of at least one magnetoresistive sensor bridge, and each arm of the sensor bridge has at least one MTJ element group. The magnetoresistive gear tooth sensor has good temperature stability, high sensitivity, low power consumption, good linearity, wide linear range, and a simple structure. Additionally, the magnetoresistive gear tooth sensor has a concave soft ferromagnetic flux concentrator, which can be used to reduce the component of the magnetic field generated by the permanent magnet along the sensing direction of the MTJ sensor elements, enabling a wide linear range. Because it is arranged as a gradiometer, the magnetoresistive gear tooth sensor bridge is not affected by stray magnetic field; it is only affected by the gradient magnetic field generated by gear teeth in response to the permanent magnet bias. The magnetoresistive gear tooth sensor of the present invention is able to detect the position of a specific tooth or a missing tooth of a gear. This magnetoresistive gear tooth sensor is also capable of determining the speed and direction of motion of a gear.
