  • Patent number: 8548768
    Abstract: The invention relates to a system for monitoring a physiological parameter of players engaged in a sports activity and a method for evaluating and treating players when the parameter exceeds a predetermined level. The system measures, calculates and records the parameter and then alerts trained personnel to apply the method to evaluate and treat players. When the system is configured for use with football, hockey or lacrosse, the system generally includes reporting units, a sideline controller, a database, and a signaling device, such as a wireless personal digital assistant. The physiological parameter data measured and collected by the reporting units are processed by the sideline controller for meaningful analysis or use. When the physiological parameter(s) exceeds a predetermined threshold level the sideline controller generates an alert that is received by the signaling device, which is typically worn by sideline personnel, such as coaching staff or trainers.

  • Publication number: 20130060168
    Abstract: The present disclosure provides system and method for monitoring of at least one physiological parameter of a person engaged in a physical activity, for example, an impact received by a player engaged in a contact sport such as football. The system includes a monitoring unit that actively monitors the physiological parameter of the person, wherein the monitoring unit generates an alert event when the monitored physiological parameter exceeds a threshold of the parameter. The monitoring unit determines whether the parameter exceeds an over-exposure threshold, wherein said threshold is based upon both a single incidence or cumulative incidences.

  • Patent number: 8246354
    Abstract: A new apparatus, system and method for fall prevention training is provided that delivers, studies and analyzes the biomechanics of a disturbance event, such as a slip or trip incident, so that an appropriate response can be executed by the person to reduce or eliminate the number of falls experienced. The apparatus includes a platform that delivers a disturbance event in less than about 500 ms and preferably in the range of about 100 ms to about 200 ms. The method includes a unique protocol for fall prevention training using the apparatus. The disturbance event can create instability in the joint of the individual. An individual's walking gait can be monitored with the portions thereof detected. A disturbance event can be triggered when a given portion of the walking gait is detected. Also, the disturbance even can be triggered manually, at preset intervals or according to preset script.

  • Patent number: 7837640
    Abstract: The present invention provides a novel means of joint and body protection using engineered textiles to provide dynamic kinematic control within the device itself and for the underlying body part. The apparatus may be used in apparel or orthosis wherein a textile is organized about the proximal and distal aspects of a joint or body part and uses the mechanical and material characteristics of the engineered textile to dynamically control the kinetics of the body part and more specifically to prevent the body part from reaching extremes in range of motion. The engineered textiles can be designed to provide non-uniform increases in stiffness in any direction. The engineered textile may incorporate strain or strain rate dependant materials in which case stiffness properties would vary non-uniformly with velocity and/or acceleration within the device allowing for protection from blunt trauma, blast, or ballistic events anywhere on the body.

  • Patent number: 7526389
    Abstract: The present invention provides an apparatus and method for determining the magnitude of linear and rotational acceleration of an impact to a body part. The apparatus can be used with protective sports equipment, such as a sports helmet, wherein the apparatus includes a battery, a number of accelerometers positioned proximate to the outer surface of the head, and an electronic device with a processor and a transmitter to transmit data received from the accelerometers. To maximize the battery life and minimize power consumption by the electronic device, the apparatus includes a power management system with a sensor assembly. The sensor assembly sends a first signal to the electronic device to initiate operation when the sensor assembly detects the presence of an object with the helmet, and a second signal to the electronic device to cease operation when the sensor assembly detects the absence of the object.
