Abstract:
A system for determining airtime of a moving sportsman includes at least one accelerometer for detecting vibration or acceleration of the sportsman. A processor in communication with the at least one accelerometer processing signals from the accelerometer to determine free-fall. A pressure sensor may be used to determine change in altitude and the processor may process signals from the pressure sensor with the accelerometer signals to determine airtime and drop distance during free-fall. A method for determining airtime of a moving sportsman includes processing data from one or more accelerometers attached to the sportsman, to determine when the sportsman is in free-fall, and determining a time period corresponding to the free-fall.

Abstract:
A location measurement system comprises: a GPS receiver for attachment to a person and for determining earth location of the person; a display for attachment to the person; memory for storing map data; a processor configured to process earth location and the map data to instruct display the person's current location with a map on the display.
Abstract:
A system for determining airtime, speed and/or drop distance of a moving sportsman includes at least one accelerometer for detecting vibration or acceleration of the sportsman and/or a GPS unit. A processor in communication with the at least one accelerometer may process signals from the accelerometer to determine free-fall.
Abstract:
A system assesses activity of a sportsman engaged in board sports. At least one sensor detects movement of the sportsman, and a processor processes data from the sensor to assess activity of the sportsman. Activity of sportsmen engaged in human powered sports is compared. A plurality of activity sensing units is associated with the sportsman. Each of the units (a) attach to one of either the sportsman or to a human powered vehicle ridden by the sportsman, and (b) wirelessly communicate activity to a remote location. The activity comprising one or more of airtime, speed, drop distance, power and energy absorbed. A database, accessible by Internet and connected to the remote location, provides access to the activity via the Internet.
Abstract:
System determines impact of a helmet, comprising: accelerometer and processor, the accelerometer detecting acceleration of the helmet, the processor configured to process the signals from the accelerometer to determine impact of the helmet. System determines athletic performance, comprising: pressure sensor for sensing change in elevation; microprocessor for processing signals from the pressure sensor to determine vertical speed corresponding to the change in elevation; and display for reporting the vertical speed to a user. System assesses athletic performance, comprising: protective housing configured for attachment to a human-powered sport vehicle; GPS sensor configured with the housing for generating earth position signals; microprocessor configured with the housing for processing the signals to determine speed and distance traveled of the sport vehicle; and display configured with the housing for displaying one or both of the speed and distance traveled to a user of the human-powered sport vehicle.
Abstract:
Sensors detects loft time, speed, power and/or drop distance of a vehicle and/or person. The sensors couple with multiple persons during athletic activity. Data from the sensors downloads to a database so that users may compare athletic performances (e.g., speed) between the persons, such as through the Internet.
