The invention relates to a measuring method and a measuring system, particularly suited for measuring the function of at least one organ of a user non-invasively. The system comprises a transmitter unit (200) attached to the user's body, and a receiver unit (202). The transmitter unit (200) transfers its measurement data associated with at least one organ to the receiver unit (202), and at least one sensor (208, 210 to 214) measures other properties than the function of the user's organs when the user uses an exercise device. The measuring system includes a holder (206) having a data collection unit (204). The receiver unit (202) is secured to the holder (206), and at least one said sensor (208, 210 to 214) transfers its measurement data to the data collection unit (204). The data collection unit (204) transfers the collected measurement data to the receiver unit (202) by means of inductive interaction.
A measurement apparatus includes a speed sensor, a cadence sensor and a display portion. The apparatus further includes a transmit portion for wirelessly transmitting signals detected by the speed sensor and the cadence sensor to the display portion. The transmit portion is provided with a shaft portion extending in one direction, which rotatably supports the cadence sensor and the speed sensor. A measurement body portion including the speed sensor, the cadence sensor and the transmit portion is mounted on chain stay. The display portion is mounted on a portion of a handle in the field of vision of a rider of the bicycle, and it has functions of receiving and processing signals transmitted from the transmit portion, and displaying prescribed information. Thus, the measurement apparatus that can easily be mounted to a bicycle and the sensor apparatus applied thereto are obtained.
A system for advising an exerciser about his physical activities, associated either with displacement of the exerciser itself or of an object displaced by the exerciser, or an object displaced simultaneously with the exerciser. The system comprises a first unit for monitoring the activities. This unit is not in physical contact with the exerciser or the object, displaced by the exerciser. The first unit is capable to collect raw data defining the activities either in terms of distance or acceleration. The first unit transmits the collected raw data in a wireless fashion to a second unit, which receives the transmitted raw data, processes it and calculates various parameters, defining the said physical activities, and represents the calculated parameters in a form recognizable by the exerciser. The system enables tracking, recording and updating the relevant information, provides improved feedback and thus helps to the exercising individual to improve his performances.
A method for quantifying activity levels of an individual within a predetermined time period including measuring a plurality of activity variables from an individual during a predetermined time period, providing a plurality of activity variables with minimum and maximum threshold values and a weighing factor, calculating a subindex for each of the activity variables as a function of the minimum and maximum threshold values and the weighing factor, and calculating a sum of the activity variables to determine an activity index of an individual. A personal activity level analysis system is configured to execute the method for obtaining an activity index used in quantifying an activity level of an individual.
