GOLF DEVICE AND METHOD
First Claim
1. A portable computing system for monitoring the performance a sportsman performing a plurality of motor acts, the system comprising:
- a portable main device containing at least a timing device, a signal processing unit, a computing unit and a display unit,an external sensor unit attachable to an object used by the sportsman in said motor acts, the sensor being responsive to movement and arranged to generate a sensor output signal,wireless communication means adapted to enable wireless communication of the sensor output signal from the external sensor to the main device,whereinthe signal processing unit is arranged to extract data on the course of each of the motor acts from the sensor output signal, said data including key time points of the motor acts,the computing unit is arranged to calculate at least one statistical value representative of the users repeatability of the series of motor acts using said extracted data from the signal processing unit; and
the display unit is arranged to display the at least one of the statistical value calculated by the computing unit.

Abstract
The invention relates to a portable device and a method for monitoring the performance a sportsman performing a plurality of motor acts, such as golf swings. The device comprises at least one sensor providing an output signal, the sensor being responsive to body movements of the sportsman. A signal processing unit is used for extracting data on the course of each of the plurality of motor acts from the sensor output signal, and a computing unit is used for determining, based on the data on the course of the plurality of motor acts, at least one characteristic number describing the repeatability of the motor act. By the means of the invention, the handicap number of the golfer can be predicted with good accuracy by monitoring several his or her subsequent swings.

12. A method of monitoring the performance a sportsman performing a plurality of motor acts, the method comprising:
-
attaching a portable main device containing at least a timing device, a signal processing unit, a computing unit and a display unit, to a body part of the sportsman, attaching an external sensor unit to an object used by the sportsman in said motor acts, the sensor being responsive to movement and arranged to generate a sensor output signal, wherein the portable main device and external sensor unit comprise wireless communication means adapted to enable wireless communication of the sensor output signal from the external sensor to the main device, wherein the method further comprises; extracting data on the course of each of the motor acts from the sensor output signal in said signal processing unit, the extracted data including key time points of the motor acts, computing at least one statistical value representative of the users repeatability of the series of motor acts in the computing unit using said extracted data from the signal processing unit; and displaying the at least one of the statistical value calculated by the computing unit on the display unit. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
