Abstract: A data collection system for surfing which includes a data collection device mounted on the upper torso of the surfer or on the surf board. The device includes a clock, GPS unit, three dimensional accelerometers, three dimensional gyroscopes, and a microprocessor and data store for processing the signals from the GPS unit, three dimensional accelerometers and three dimensional gyroscopes. The microprocessor is programmed to identify and collect signal data to derive information identifying one or more parameters including number of waves passed up, power of each wave, size and frequency of the waves, time when a wave is caught, number of paddles required to catch a wave, time between catching the wave and the surfer standing up, distance travelled and speed during ride, time when rider exits the wave, acceleration during each manoeuvre during the ride, g force and speed during turns.

Abstract: An electronically trackable ball consisting of a cover, an inflatable bladder, a valve in the bladder a mounting structure attached to said valve and extending inwardly of the valve toward the center of the inflated bladder and an electronic transmission device on said mounting structure remote from said valve. The mounting structure is preferably a lightweight polymeric cylinder with the electronics fitted at the end remote from the valve and close to the center of mass of the ball. The device is within the ball, and is constrained from moving around inside the ball.

Abstract: A system for monitoring a plurality of individuals engaged in a sporting activity includes a base station; a plurality of individual participant monitors, affixed to each individual and wirelessly communicating with said base station; a plurality of sensors in each said monitor or on each individual, in communication with each monitor and configured to sense a physiological or activity parameter of the individual; each monitor transmitting data relating to parameters sensed by said sensors to the base station; one or more group monitoring devices communicating wirelessly with said base station to receive said sensed parameter data. The system displays, during said activity, data relating to one or more sports parameters of one or more individuals as well as displaying the operational status of one or more of each monitor, each sensor, and the base station.

Abstract: A system for tracking balls in sports in which players kick, pass, bounce, strike or carry a ball. The ball is equipped with two beacons pulsing in the 5-10 Hz range at a frequency which is not attenuated by the body of the players. one beacon has a very short range of 40-120 cm and the other has a range of 1-5 meters. A data logger worn by the players includes a clock, location and speed sensors, a receiver for the beacon signals and a micro controller to record the data from all the sensors. The micro controller is able to record whether the player is in possession of the ball or is contesting the ball. The path of the ball from player to player is tracked relative to the playing field. An impact or pressure sensor may be fitted to the players footwear, glove or a bat stick, club or racquet to register a kick or ball strike.

Abstract: A data logger for a monitoring sports which includes an accelerometer, a gyro sensor to sense angular displacement, a GPS unit to sense position and velocity, a magnetometer to sense direction of movement, a heart rate monitor, and a controller programmed to manipulate the data and provide a display of the heart rate, speed, and other sport parameters. The data can be stored or transmitted to a remote computer for use by the coach. The device is useful in football codes, athletics, swimming, snow sports and cycling.

Abstract: Analysing fluid samples for target biological or chemical species comprising a detector unit with a body incorporating a SAW sensor (29) for said target species, in a microfluidic channel (27) and a reader unit adapted to receive the detector unit. The reader unit includes electrical contacts with said SAW sensor and a processor to analyse the sensor signals to determine if the target is present. The detector unit includes a storage reservoir (23) for the calibrating and sample solutions arranged so that the fluid flows through the microfluidic channel over the SAW sensor to a storage reservoir. The sensor is calibrated by using a first liquid having a known quantity of a form of the target species to provide a first frequency change and then a sample solution to be measured and measuring a second frequency change and using the first and second measurements to calibrate the sensor and determine the quantity of the target in the sample solution.
