System and methods for determining performance data
View Patent ↗The invention determines performance data during activity of a person. A microprocessor and a sensor, such as a GPS sensor, attach to the person or to a vehicle ridden by the person. The sensor and microprocessor may integrate in clothing or in a watch worn by the person. Wireless signals may be generated to a remote base station or to a watch. Performance data may for example include speed, drop distance, airtime and power.
1. A system for determining motion characteristics of a sportsman, comprising:
an accelerometer-based sensor for attachment with the sportsman, the accelerometer based sensor sensing acceleration of the sportsman during movement and processing the acceleration to determine airtime of the sportsman during the movement; and
a watch to be worn by the sportsman, the sensor wirelessly communicating data incorporating the airtime to the watch, the watch receiving the data and indicating the motion characteristics.
2. A system of claim 1 , the sensor further processing the acceleration during the airtime to determine the motion characteristics, the sensor wirelessly communicating the data between the sensor and the watch to report, through the watch, the motion characteristics to the sportsman.
3. A system of claim 2 , the motion characteristics comprising one or both of speed and distance traveled.
4. A system of claim 1 , the sensor further processing the acceleration during the airtime to determine the one or both of distance traveled and speed of the sportsman during the airtime, the sensor wirelessly communicating the data between the sensor and the watch to report, through the watch, at least one of the speed said distance traveled as the motion characteristics to the sportsman.
