The game may be the same, but the gear is different: This Saturday, as NFL prospects try to impress coaches at the Combine workouts, a few players will don smart shirts–souped-up sports attire that measures everything from players’ heart rates to g forces of acceleration.
Designed by Under Armour and Zephyr, this sophisticated shirt is called the Under Armour E39. It weighs less than 0.3 pounds and boasts a load of sensors that sit just below the athlete’s sternum; the sensors include a triaxial accelerometer, a heart-rate monitor, and a breathing-rate monitor. As an athlete practices, trainers can follow the player’s vital signs on their smartphones, laptops, or any other device that can receive Bluetooth data. As Wired explains:
“What we have is something very close to the body’s center of mass that’s measuring the accelerometry data from that center of mass,” Under Armour vice president Kevin Haley told Wired.com.
How much time and energy is wasted as drivers circle around blocks and creep down streets, on the prowl for open parking spots? Burning fuel, they simmer silently in their seats, running late for work and appointments. Thankfully, technology has some solutions to ease the pain of finding parking.
Engineers Marco Gruteser and Wade Trappe of Rutgers University have combined ultrasonic sensors, GPS receivers, and cellular data networks to create a handy and ultra-cheap “parking-spot finder.” Their system distributes the task of finding vacant parking spots to sensors placed on a number of roving vehicles, and then combines the info to make a map of all the available parking in a region. That map could theoretically be accessed through smart phones or dashboard navigation devices.
