Abstract: An apparatus for training a waist portion of a human body is disclosed. In the apparatus, sprockets are installed on a portion on which a trainer sits and on another portion which his hands grasp, a drive chain extends between the sprockets so as to drive the sprockets in mutually opposite directions. Therefore, transmission loss of the pivotal energy between the two portions is reduced. In addition, a brake drum and pair of brake shoes are provided to adjust resistance to the pivotal movements between the portions, therefor adjustment of the resistance can be achieved without electrical power.

Abstract: In an automatic shift control system for a vehicle equipped with an automatic transmission, during the control of the gear ratio of the automatic transmission in accordance with a shift pattern predetermined in accordance with the driving conditions of the vehicle, the shift pattern is corrected in a gear ratio downshifting direction in response to a curved running detection signal detecting the curved running of the vehicle.

Abstract: A signal proportional to a vehicle speed is applied to one input terminal of a differential amplifier, and the output of the differential amplifier is fed back to the other input terminal of the differential amplifier via a switch the on-time of which is proportional to consumed fuel. Then, the output of the differential amplifier is taken out as a fuel consumption signal for informing a vehicle driver the momentary fuel consumption of the vehicle on a voltmeter or ammeter.

Abstract: A heart pulse rate measuring system comprises a casing, a pair of rod-shaped grip sensors extending outwardly from the opposite sides of the casing for sensing a heart pulse signal, and an electric circuit for calculating a heart pulse rate from the sensed heart pulse signal. Each of the grip sensors is composed of two conductive cylindrical electrodes arranged in an axially aligned relationship and electrically insulated from each other for obtaining a pulse rate utilizing the potentials at four points in a user's body. The electric circuit includes a differential amplifier, having a ground connection to one of the two electrodes of each sensor and two inputs for the remaining electrodes. A filter is used to eliminate noise from the output of the differential amplifier, and a computer calculates the heart rate from the output of the filter.

Abstract: A small portable-type apparatus for checking pulse or heart rate of a person engaged in exercise. Therefore, the apparatus according to the present invention can be used as a pulsimeter or a cardiometer according to the state of a person in motion. The apparatus is provided with a heart sensor having a plurality of cone-shaped conductive rubber electrodes to differentially detect an electrocardiowave voltage signal generated from three different places near the heart and a pulse sensor having a matching infrared-ray emitting diode and infrared-ray receiving phototransistor to detect the light reflected from the blood flowing through capillary vessels under the finger pad. The apparatus additionally functions as a stopwatch or a timer as selected by a mode-selector switch.

Abstract: A method and apparatus for indicating mileage corresponding to remaining fuel for vehicles includes a microprocessor connected to receive input signals respectively indicating a traveled distance and a consumed fuel quantity in a predetermined short period. During such time when quantity of fuel remaining in the tank is above a certain threshold level, the mileage corresponding to the remaining fuel is calculated by multiplying the remaining fuel quantity by a fuel consumption (Km/l) which substantially corresponds to the average fuel consumption during a period between two recent successive fillings of the fuel tank. After the remaining quantity of fuel has reduced below the threshold level, the value of the fuel consumption is updated by increasing the weight of the momentary fuel consumption which reflects the actual running condition.

Abstract: An indication apparatus which detects a plurality of abnormal conditions occurring in a motor vehicle particularly in an automobile, and indicates an indicium corresponding to one of the abnormal conditions. When at least one of a plurality of sensors detects the occurrence of the plurality of abnormal conditions, a motor control circuit drives a motor whereby an indication drum coupled with the motor is also rotated so as to be stopped at a location for indicating the indicium corresponding to the detected abnormal condition. In order to investigate whether abnormal conditions other than the detected one have occurred or not, a switch for forcibly rotating the indication drum can be manually actuated so that the indication drum is further rotated so as to be stopped at a location for indicating another indicium corresponding to one of the other abnormal conditions and thus the other abnormal conditions are indicated successively.

Abstract: An indication system for indicating abnormal conditions on an indication drum. A rotary switch having a plurality of stationary contacts connected to a plurality of sensors and a movable contact connected to the indication drum is provided to control the rotation of the indication drum. Receiving an output signal of one of the sensors, the rotary switch rotates together with the indication drum until the movable contact comes into contact with one of the stationary contacts to which the output signal is applied. The indication drum, then, indicates one abnormal condition represented by this output signal. A manually-operated switch is further provided to forcibly rotate the movable contact. When the manually-operated switch is activated, the movable contact is caused to slide over the stationary contacts so as to detect another output signal representing another abnormal condition to be indicated.

Abstract: An indication apparatus indicates a highest priority one of a plurality of simultaneously occurring abnormal states of a vehicle. When one of a plurality of abnormal state sensors is opened, a drive motor coupled to an indication drum starts to rotate and stops when a position on the indication drum indicating above abnormal state sensor is reached. When another sensor having higher priority than the first sensor is also opened, the indication drum rotates to the position corresponding to the second higher priority sensor, but when a sensor having a lower priority is further opened the indication drum remains fixed at the position corresponding to the first sensor.
