The Sport Sensors Glove Radar is a small inexpensive Doppler radar velocity sensor which attaches to a baseball or softball glove to measure the speed of the ball just before it is caught. It is easily attached to, and removed from virtually any ball glove. The clever design of this sport radar gun results in a small, versatile, low-cost device, affordable for youth and senior level teams and individual players.
The purpose of Sport Sensor Glove Radar is to assist in developing players' throwing capabilities by providing a measure of velocity improvement which results from using proper throwing techniques. By learning the proper way to condition, train, warm-up, and throw, players can achieve their best accuracy and velocity performance, while reducing the risks of injury to their arm and body. The SportSensor Glove Radar can aid any player - infielders and outfielders, as well as pitchers and catchers, throwing from any distance. Professional and amateur players can use the Glove Radar when warming-up. Young ballplayers will benefit from velocity information when tossing or training, and will have fun using it.
When worn by the receiver of the ball, or by multiple tossing partners in non-game situations, the Glove Radar responds to the approaching ball just before it reaches the glove. Thus, unlike most "radar speed guns", a long range capability is not required. Powered by a single cell lithium battery, the Glove Radar transmission level is well below that of most "wireless" consumer products such as cellular and portable telephones, for example. Transmission characteristics are well within FCC requirements and prescribed safety levels. The Sport Sensors GloveRadar is microprocessor controlled, like a mini-computer, and indicates calculated miles-per-hour ball speed on a liquid crystal display (LCD). Subsequent international models will display appropriate units of measure.
The Glove Radar is packaged in a rugged plastic housing assembly, sealed to protect the internal electronics from dust, dirt and moisture which can be encountered during normal use. However, the unit is not hermetically sealed and is not intended to be immersed in water.
Two screws hold the cover in place, which can be removed to replace the internal battery. A strong, weather-resistant nylon cord, facilitates attachment to virtually any ball glove. (Attachment details are discussed on the Glove Attachment page.) A rubber pad, molded onto the housing surface adjacent to the glove, absorbs impact "shock" forces from the ball being caught.
The internal electronics are in "sleep" mode until activated by depressing the push-button "on" switch. This action applies electrical power from the battery to the radar transmitter. The liquid crystal MPH display will indicate the last velocity reading. Depressing the push-button again will cause the display to show a flashing "00", indicating that the Glove Radar is transmitting. Upon receipt of a velocity signal produced by a ball about to be caught in the glove, the ball speed is calculated and shown on the display in miles-per-hour. Receipt of a velocity signal turns off the radar transmitter until the "on" switch is depressed. If a velocity signal is not received within 20 seconds after depression of the push-button "on" switch, electrical power is automatically removed from the radar transmitter until the switch button is again depressed. Limiting the "on" time of the radar transmitter conserves battery power in order to maximize battery life. The last velocity reading continues to be displayed. However, the Glove Radar goes into the sleep mode after an inactivity period of about a minute.
