  • Exercise amount measuring device capable of displaying the amount of exercise to be performed further
    Patent number: 5989200
    Abstract: Total consumed calories are indicated in an upper portion of a display. A life activity intensity of each of the past seven days and an average life activity intensity over the same period are indicated by a bar graph in a lower portion of the display. The life activity intensity is classified into rank I (light), rank II (medium), and rank III (a little heavy). A total exercise amount (i.e., total consumed calories) and a life activity intensity are calculated and automatically displayed at the end of a day.
    Type: Grant
    Filed: April 2, 1998
    Date of Patent: November 23, 1999
    Assignee: Omron Corporation
    Inventors: Manabu Yoshimura, Maki Hasegawa, Tsukasa Hatakenaka, Makoto Tabata, Tsutomu Yamasawa, Masaaki Takenaka, Tomoo Watanabe, Kazuyuki Morita
  • Vibration sensor including a movable magnet positioned between stationary magnets
    Patent number: 5834649
    Abstract: A vibration sensor includes a first stationary magnet, a second stationary magnet, a movable magnet positioned between the first and second stationary magnets, and a sensor for sensing movement of the movable magnet. The movable magnet is disposed in a magnetically repulsive relationship with the first stationary magnet and a magnetically attractive relationship with the second stationary magnet.

  • High speed response temperature sensor
    Patent number: 4688949
    Abstract: In this high speed response type temperature sensor, a base body member is formed as a hollow tube with one closed end and one open end, and a temperature sensitive sensor layer is formed over at least part of its external surface. An electrode layer is arranged at at least a part of the periphery of the open end of the base body member, in contact with a part of the temperature sensitive sensor layer, and a protective cover layer is formed over at least a part of the sensor layer. Thus, since this sensor layer is formed on the external surface of the hollow tubular base body member, the opposing and contacting area between the sensor layer and the object whose temperature is to be measured becomes relatively large, and the distance therebetween is also reduced, so that the efficiency of heat conduction from the object to the sensor layer is greatly improved. Because the base body member is hollow, also, the overall heat capacity is greatly reduced.
