Methods and systems are disclosed for determining speed, power and/or impact (sporting characteristics) of persons involved in activity. Wireless signals may be generated indicative of the sporting characteristics for receipt and display on a watch worn by the user or on a remote display. Sensors may attach to the person or to a vehicle ridden by the person, to gauge activities such as jogging, hockey, biking, football and aerobics.

No. 6,498,994) and entitled Systems and Methods for Determining Energy Experienced by a User and Associated with Activity, which is a continuation of U.S. application Ser. No. 08/867,083, filed on Jun. 2, 1997 (now U.S. Pat. No. 6,266,623) and entitled Sport Monitoring Apparatus for Determining Loft Time, Speed, Power Absorbed and Other Factors Such as Height, which is a continuation-in-part of U.S. application Ser. No. 08/344,485 filed on Nov. 21, 1994 (now U.S. Pat. No. 5,636,146) and entitled Apparatus and Methods for Determining Loft Time and Speed, each of which are hereby incorporated by reference.
A method and apparatus for estimating a motion parameter corresponding to a subject element employs one or more accelerometers operable to measure accelerations and a processing system operable to generate a motion parameter metric utilizing the acceleration measurements and estimate the motion parameter using the motion parameter metric.
A system determines impact of a helmet. The helmet includes at least one accelerometer and a processor. The accelerometer detects acceleration of the helmet. The processor is configured to process the signals from the accelerometer to determine impact of the helmet.
An approach to monitoring, evaluation, diagnosis, treatment or conditioning of animals such as horses does not require use of restrictive equipment such as treadmills or force plates and that can provide either or both of more or less immediate or continuous processing of data to perform the monitoring or diagnosis. One or more wireless sensors are attached to the animal, for example, to measure motion-related parameter associated with one or more parts of the animal. Sensor data is received from the sensors and processed to identify a characteristic of the motion of the animal, such as a quality of gait. The sensor data can also be used to avoid injury to the animal and/or the rider, and to verify the identity of an animal.

An activity monitor, comprises housing for attachment to a person; at least one accelerometer disposed within the housing; and a processor disposed within the housing, for processing signals from the accelerometer to assess activity of the person. A method assesses activity of a person, including: sensing acceleration at a first location on the person; processing the acceleration, over time, to assess activity of the person; and wirelessly communicating information indicative of the activity to a second location.
