Abstract: This invention relates in general to target games and methods for animating a target game and playing an animated target game. In the present invention, a game with an animated component comprises a target structure having a first target surface and a second target surface. In some embodiments, the first target surface is separated from the second target surface by a joint. An animation mechanism is provided for moveably connecting the first target surface to the second target surface at the joint.

Abstract: The invention relates to a system and method for providing feedback to a user on his or her running style or running technique. The system employs a pressure sensitive surface to record a gait line of the center of pressure exerted by the user's foot on an underlying surface during a footstep period. In case of a fore or mid-foot landing the gait line may be observed to move backwards with respect to the sagittal plane. From a backwards-going gait line two time stamps are determined. The first timestamp T1 is the time that the foot strikes the ground. The second timestamp T2 is the time that the gait line reaches the most backward position. From the time difference between these two timestamps a loading time dT is determined. The reactivity of the running style describes the viscoelastic behavior of the muscle-tendon unit and may be calculated as a function of this loading time and/or the distance moved by the center of pressure backwards towards the heel.

Abstract: The invention is a trigger pull training device for improving trigger pull technique. The device has a frame with a trigger track opening and a trigger which goes through that opening. A proximity sensor or a plurality of proximity sensors are placed proximate the trigger track opening. The sensors are connected to an indicator whereby pulling the trigger such that the trigger is within the sensing zone causes the proximity sensor to emit a signal. A plurality of sensors can be lined along the trigger track opening to indicate the accuracy of any pull.

Abstract: A method and system for measuring energy expenditure of individuals by measuring force from a plurality of foot-borne force sensitive resistors and calculating incline from a foot-borne tri-axial accelerometer.

Abstract: This invention relates to impact sports, and to articles of clothing and for detection systems used to monitor and registering the intensity, location and sources of impacts in contact sports such as boxing, martial arts, fencing, and so forth.

Abstract: A practice device comprising a plurality of striking targets arranged about a frame in an overall configuration which approximates the shape of an opponent. The targets are individually articulated to the frame, so that each individual target reacts independently in response to a strike. The targets are each in communication with a common force sensor, through a load transfer shaft movable relative to the frame and bearing on a force sensor such as a load cell, which provides feedback to the athlete regarding the force of each strike.
