Head Impact Telemetry System
Head Impact Telemetry System (HITS) is a hardware and software system intended as a shock detector and logger; the hardware is embedded in football helmets and transmits data to a computer. The system was developed by Simbex, based on Lebanon, New Hampshire, in collaboration with Virginia Tech Virginia Tech (formally the Virginia Polytechnic Institute and State University and informally VT, or VPI) is a public land-grant research university with its main campus in Blacksburg, Virginia. It also has educational facilities in six re ..., starting around 2000. By 2006 the system weighed about six ounces and had six sensors, a small computer, a battery and a radio; helmets including the system were marketed by Riddell and a set of 40 cost around $50,000 at that time. At that time nine NCAA football teams and a high school team were testing it, and the NFL had decided it not well validated enough to use.

Shock Detector
A shock detector, shock indicator, or impact monitor is a device which indicates whether a physical shock or impact has occurred. These usually have a binary output (go/no-go) and are sometimes called ''shock overload devices''. Shock detectors can be used on shipments of fragile valuable items to indicate whether a potentially damaging drop or impact may have occurred. They are also used in sports helmets to help estimate if a dangerous impact may have occurred.Harris, C. M., and Peirsol, A. G. "Shock and Vibration Handbook", 2001, McGraw Hill, ISBN 0-07-137081-1 By contrast, a shock data logger is a data acquisition system for analysis and recording of shock pulses. Overview Shocks and impacts are often specified by the peak acceleration expressed in g-s (sometimes called g-forces). The form of the shock pulse and particularly the duration are equally important. For example, a short 1 ms 300 g shock has little damage potential and is not usually of interest but a 20 ms ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shock And Vibration Data Logger
A shock data logger or vibration data logger is a measurement instrument that is capable of autonomously recording shocks or vibrations over a defined period of time. Digital data is usually in the form of acceleration and time. The shock and vibration data can be retrieved (or transmitted), viewed and evaluated after it has been recorded. In contrast with a shock data logger, a shock detector is used to indicate whether or not the threshold of specified shock has occurred. Functions A logger comprises sensors such as accelerometers, storage media, a processor and power supply. The sensors measure and store shocks either as the entire waveform, summary data, or an indication of whether a threshold value was observed . Some devices have accelerometers built into the unit while others can use external accelerometers. The processor processes the measured data and saves it on the storage media together with the associated measurement times. This allows the measurement data to be ...

Football Helmet
The football helmet is a piece of protective equipment used mainly in gridiron football, although a structural variation has occasional use in Australian rules football. It consists of a hard plastic shell with thick padding on the inside, a face mask made of one or more plastic-coated metal bars, and a chinstrap. Each position has a different type of face mask to balance protection and visibility, and some players add polycarbonate visors to their helmets, which are used to protect their eyes from glare and impacts. Helmets are a requirement at all levels of organized football, except for non-tackle variations such as flag football. Although they are protective, players can and do still suffer head injuries such as concussions. Football helmets have changed dramatically with the modernization of the sport to facilitate technological changes and to improve the safety of the game. Despite lower rates of some injuries, serious traumas to the head are still common, and determini ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lebanon, New Hampshire
Lebanon is a city in Grafton County, New Hampshire, United States. The population was 14,282 at the 2020 census, up from 13,151 at the 2010 census. Lebanon is in western New Hampshire, south of Hanover, near the Connecticut River. It is the home to Dartmouth–Hitchcock Medical Center and Dartmouth College's Geisel School of Medicine, together comprising the largest medical facility between Boston, Massachusetts, and Burlington, Vermont. Together with Hanover, New Hampshire, and White River Junction, Vermont, Lebanon is at the center of a Micropolitan Statistical Area, encompassing nearly 30 towns along the upper Connecticut River valley. History Lebanon was chartered as a town by colonial governor Benning Wentworth on July 4, 1761, one of 16 along the Connecticut River. It was named for Lebanon, Connecticut, from where many early settlers had come or would come, including the Rev. Eleazar Wheelock, who arrived in 1770 and founded Dartmouth College.

Riddell Sports Group
Riddell Sports Group is an American company specializing in sports equipment for American football. It was headquartered in Rosemont, Illinois. In 2017, the company relocated to a new facility in adjacent Des Plaines, Illinois. The company was started by John Tate Riddell. He first invented the removable cleat, and then went on to invent the first ever plastic suspension helmet in 1939. In 2008, Dan Arment was appointed president of Riddell. Arment previously worked as executive vice-president and general manager of mass-market business for BRG Sports, Riddell's parent company, which is owned by private equity firm Fenway Partners.
