A text classifier and building the text classifier by determining appropriate parameters for the text classifier.

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.

A new football helmet includes: a jaw flap attached to the ear flap of the helmet, and the jaw flap overlies the sides of the lower jaw of football player; and a face guard connector which includes a shock absorbing member.

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.

The protective helmet (1) comprises a deformable foam liner (7), a plurality of shell segments (9), and joining means made of flexible material performing joining between the shell segments (9). The shell segments (9) are arranged on the foam liner (7) so as to form at least one crown segment (9a), at least one occipital segment and a plurality of transverse side segments (9c). The shell segments (9) and the joining means made of flexible material are joined to the foam liner (7) in such a way as to allow a slight sliding between the foam liner (7) and at least a part of the shell segments (9). The helmet (1) preferably comprises a headband adjustment means (14) designed to adjust the size of the helmet (1) and to optimize user comfort.

This invention relates to active protective garments which are inconspicuously worn by an individual and which activate upon certain conditions being met. Activation causes inflation of regions of the active protective garment to provide padding and impact cushioning for the wearer. The invention is an active protective garment such as pair of shorts or pants, a jacket, a vest, underwear, and the like. The garments comprise multiple layers of material that constrain pockets or regions that are inflatable by a source of compressed gas or foam. The garments also comprise sensors to detect ballistic parameters such as acceleration, distance, relative acceleration, and rotation. The sensor information is used to determine whether activation is required. Detection and activation are accomplished in a very short time period in order to offer maximal protection for the individual wearing the garment. The system comprises a computer or logic controller that monitors the sensor data in real time and coordinates the information from all sensors. The system calculates velocity, distance, and rotational velocity. A rule-based system is used to detect a complex fall in progress and discriminate said fall in progress from the events of every day life. The pockets or inflatable regions of the garment protect the individual against falls and other impacts that may cause bone fracture or organ damage.
