Abstract
A measuring system (1) comprises a sensor (6) arranged to be attached to a subject for obtaining a measured value representing a physical or a physiological quantity of the subject. The measuring system further comprises means for deriving a subject-related value from the measured value. The sensor is arranged to be attached at one of a plurality of positions on the subject. The measuring system further comprises means for establishing the position of the sensor on the subject. The means for deriving the subject-related value is arranged for deriving the subject-related value also in dependence on the position of the sensor on the subject.
Claims20
A device for monitoring activity of a subject, the device comprising:
- a sensor attachable to a plurality of positions on a body of the subject, the sensor comprising an accelerometer configured to provide a measurement value descriptive of a motion of the subject;
- a processor in communication with the sensor;
- and
- a non-transitory storage medium storing instructions that, when executed by the processor, cause the processor to:
- determine a current position of the plurality of positions on the body of the subject at which the sensor is positioned;
- determine whether the current position is a predetermined reference position;
- when the current position is determined to be the predetermined reference position, compute an activity parameter of the subject from the measurement value;
- and
- when the current position is determined not to be the predetermined reference position, compensate the measurement value for a difference of the measurement value at the current position and a corresponding value at the predetermined reference position, and compute the activity parameter from the compensated measurement value.
A non-transitory machine-readable medium storing instructions for execution by a processor, the non-transitory machine-readable medium comprising:
- instructions for receiving a measurement value from a sensor attached to a body of a subject, wherein sensor comprises an accelerometer and the measurement value is descriptive of a motion of the subject;
- instructions for determining a current position of the sensor from a plurality of positions on the body of the subject based on the measurement value;
- instructions for determining whether the current position is a predetermined reference position;
- instructions for computing an activity parameter of the subject from the measurement value when the current position is determined to be the predetermined reference position;
- and
- instructions for compensating the measurement value for a difference of the measurement value at the current position and a corresponding value at the predetermined reference position, and computing the activity parameter from the compensated measurement value, when the current position is determined not to be the predetermined reference position.
A method for execution by a processor for adapting an activity monitor to a placement of a sensor of the activity monitor on a body of a subject, the method comprising:
- receiving a measurement value from the sensor attached to a body of a subject, wherein sensor comprises an accelerometer and the measurement value is descriptive of a motion of the subject;
- determining a current position of the sensor from a plurality of positions on the body of the subject based on the measurement value;
- determining whether the current position is a predetermined reference position;
- when the current position is determined to be the predetermined reference position, computing an activity parameter of the subject from the measurement value;
- and
- when the current position is determined not to be the predetermined reference position, compensating the measurement value for a difference of the measurement value at the current position and a corresponding value at the predetermined reference position, and computing the activity parameter from the compensated measurement value.
