The Winning Time chip timing system is designed around the TIRIS RFID (radio frequency identification) technology developed by Texas Instruments, which delivers proven and highly reliable performance. We've successfully timed everything from large marathons, densely-packed nordic ski racing and cycling races where sprinters cross the finish line at 40mph. There are three main elements to our system: The Chip, Box and Antenna.The ChipThe Winning Time transponder (known as a "Chip") is an extremely light passive radio transmitter, without any battery. It consists of a micro antenna and an integrated circuit which can transmit a unique 20 digit code. The Chip is inserted into a special hard plastic casing and can be worn by the athletes on an adjustable easy-on/ easy-off Velcro ankle strap. The chip can also be mounted on a bicycle's front fork with a special lightweight support case.The BoxThe controller boxes are used wherever athlete data must be captured: starting lines, split check points and finish lines. The controller box houses the TIRIS RFID modules (chip readers), which are controlled by Winning Time's proprietary CPU. The boxes also contain long-life internal batteries that are easily recharged between events.Our weatherproof controller boxes connect to multiple mat antennas – a Winning Time exclusive – that capture chip data (ID code & race time) as athletes pass over them. Numerous communications ports provide connectivity options between the controller boxes and the scoring computer. The robust design and construction of the boxes allows them to withstand the rigors of constant use and transportation. They are built to last!The AntennaThe Winning Time antennas are made of plastic and covered with a robust non-deformable rubberized material. A single Winning Time antenna mat measures 160 cm long by 120 cm wide and weighs only 20 pounds. Because of its unique design each antenna mat is lightweight, easy to handle by just one person and non-deformable. They are easily joined together to create any required configuration for starts, finish lines or intermediate check points.
