Definitions

• the present invention relates to an electronic performance- measuring device, e.g. a personally carried ergometer which measures the physical work or the physical stress a person is subjected to.
• a personally carried ergometer which measures the physical work or the physical stress a person is subjected to.
• Such an ergometer can he used for measuring the physical activity during daily activity as well as during intensive physical activities, e.g. in connection with participation in sports.
• the described disadvantages are circumvented and a number of advantages obtained.
• the momentary value of the acceleration is sensed continually and a time integral formed to attain the speed and also a further time integral for obtaining the magnitude of the displacement.
• the vertical acceleration is measured.
• the mentioned factor can then include information as to age, weight, length sex or other personal data which, in a mode already known, constitute parameters for physical performance.
• age, weight, length sex or other personal data which, in a mode already known, constitute parameters for physical performance.
• the mentioned factor can then also contain an increment for this development of energy, put in relation to the values for movement upwards in the case where only upward movement is measured.
• Other factors can also be incorporated in this factor, e.g. the efficiency of a certain kind of work.
• the disadvantages discussed are avoided and the above-mentioned advantages obtained by the ergometer in accordance with the invention containing an accelerometer.which is adapted for giving a continuous signal corresponding to the momentary acceleration, and that the ergometer includes means for calculating force, power and/or energy.
• the ergometer contains a multiplier, adapted to multiply the acceleration signal with a factor for the purpose of obtaining a measurement of the force causing the acceleration.
• the ergometer also includes means for integrating the acceleration signal with respect to time for the purpose of obtaining a signal for the momentary velocity and development of power.
• the ergometer in accordance with the invention includes means for integrating the signal for the momentarily developed power for a given period of time for the purpose of obtaining a value for the work developed during the period.
• the ergometer can further include an indication means, arranged in a digital or analogue form for showing the values for force, momentary power and/or developed work and the amount of corresponding energy expended by a person.
• the ergometer includes memory or registering means adapted for storing values for force, momentary power and/or developed work at different times during a defined period of time.
• the ergometer includes means arranged to give a signal in response to a definite value of the momentary power or effort and/or work developed.
• the ergometer in one embodiment includes means for measuring the acceleration in at least two directions, there are also being means adapted for calculating force, power and/or work developed in said directions.
• the developed work inputs measured in the different direc tions can be combined into a value for total work performed.
• the ergometer also includes, in a seventh embodiment, a means for measur ing and/or registering the number of heartbeats.
• a means for measur ing and/or registering the number of heartbeats In this way, values of force, power and/or developed work in relation to heart activity can be obtained, which gives in- teresting information concerning the heart response to the work performed during a day's work, for example, or during some executed physical performance.
• a pocket ergometer in this embodiment opens the way for ob taining a quantitative measurement of different types of stress.
• this comprises, in accordance with the in vention, a polarized ceramic spring, one end of which is rigidly fixed.
• the spring can be provided with a mass, e.g. of lead, at its free end.
• the signal from the ceramic spring is taken out via two terminals, one on either side of the spring at its place of fixation.
• the accelerometer for measuring the movement acceleration is denoted by the nume ral 1.
• the signal corresponding to the acceleration is taken to component 2 which is an electronic calculating unit for processing all the data with which the ergometer operates.
• the electronic computer 2 is also supplied with the signal from a transducer 3 for giving heart-pulse signals.
• Prom a plurality of components, denoted by the numerals 4—9 there are fed in values for gravitational force/acceleration, movement resistance, mass or burden, personal information such as body weight, efficiency and calibrating constants.
• the computor is fed limiting values from a component 10 for different values, e.g. signal values, e.g. signal values of momentary power and work executed.
• Prom the electronic computer 2 output signals are taken to a display 11, which can have three different indication areas, such as 11a for force, 11b for momentary power development and 11c for work performed.
• a memory unit can be connected to the computer output, said unit storing the calculated measured values possibly presented in the display 11, or other values at given times or during a given period of time.
• the computer is finally connected to an acoustical or optical signal transmitter 13, coming into function when set limiting values from the unit 10 are attained.
• the signal from the accelerometer 1 can be multiplied in the computer 2 by a factor which is dependent, for example, on values obtained from the component 6 for mass and com ponent 9 for calibration constants, whereby the force which causes the acceleration can be calculated and whown on the display 11.
