In 1932 three systems were used: official hand timing, hand started photo-finish times, and the Gustavus Town Kirby timing device, which was designed by Kirby to determine the correct order of finish in horse races. The official report for 1932 Olympics states: "In addition to hand timing, two auxiliary electrical timing devices were used.
When drivers are preparing to race, they move the vehicle and interrupt light beams 7 in (180 mm) behind the starting line. Crossing this beam activates the top half of the blue lights; on typical trees, which were used at national events prior to April 2011, and still used for regional and club events, this is the top set of two small amber bulbs, labelled "Pre-Stage".
Transponder timing (also called chip timing or RFID timing) is a technique for measuring performance in sport events. A transponder working on a radio-frequency identification (RFID) basis is attached to the athlete and emits a unique code that is detected by radio receivers located at the strategic points in an event.
The Jaguar system was introduced in August 2008 after beta testing at 50 events. [6] [7] ITS holds a patent for using a foam backing to separate transponders from the sweat-covered skin of athletes, [8] among other inventions. In addition to offering Jaguar timing systems and a variety of transponders, ITS also manufactures race clocks. [9]

In particular, 802.1AS defines how IEEE 802.3 , IEEE 802.11 , and MoCA can all be parts of the same PTP timing domain. [14] SMPTE 2059-2 is a PTP profile for use in synchronization of broadcast media systems. [15] The AES67 audio networking interoperability standard includes a PTPv2 profile compatible with SMPTE ST2059-2. [16]
In an external combustion engine, such as a steam engine, the control of the valve timing is by the valve gear. In a typical piston valve arrangement, the timing of the intake and exhaust events for each cylinder are inextricably related as they are governed by the movement of a single piston uncovering two ports. However, the duration of the ...
The sale included 17 acres of adjacent, undeveloped land.
