  • Patent number: 5285396
    Abstract: A device for evaluating a plurality of race horses' readiness for a race by quantitatively assessing the horses' temperatures without contacting the horses, the evaluation being made prior to the race when the race horses may be viewed in a paddock area. The device may include an infrared sensor for measuring the horses' temperatures at least three times in a random sampling period, an arithmetic operator for calculating characteristics of those measurements such as the maximum, minimum and mean, and various differences among the measured temperatures, and a display for providing a visual comparison of the measured and calculated values. The device may also correct the measured temperatures for the distance from which temperature measurements were taken.

  • Patent number: 4404626
    Abstract: A method and apparatus for controlling the deceleration of a motor driven body in which deceleration is controlled as a function of the difference between the output energy of the driving motor and the kinetic energy of the driven body.

  • Patent number: 4311945
    Abstract: In carrying out location control of a control object by decelerating a driving source for the control object over a suitable number of stages, this invention is based on the conception that inertia and strain occur in the control object, the driving source keeping such output as to allow a uniform motion of the control object and transmission mechanisms connecting them due to the uniform motion of the control object in a preceeding stage, and they exert significant influences over the location accuracy of the control object and wearing of the machine. In the present invention, therefore, the driving source of the control object is brought under deceleration control at such a timing where the strain occurring in the control object and its associated mechanisms becomes minimum.

  • Patent number: 4081732
    Abstract: The invention relates to an automatic positioning apparatus which is primarily adapted to control the position of a movable part of a machine tool such as a tool rest of a lathe in response to an output signal of a means for measuring the distance of travel of the movable part, and the output signal of a setting circuit on which parameters of motion of the movable part may be preset.
