Here’s How On-Field Player Tracking Tech Works

Sensors in sports activities as we all know them will be traced again to 1996’s introduction of the FoxTrax illuminated hockey puck, an augmented actuality enhancement that made it simpler to see the puck on TV. When Mediaweek first reported on the event of the puck in June 1995, Fox Sports’ then-president David Hill would not affirm or deny the story, albeit whereas conceding that Fox was engaged on one thing. “[We are] looking at every opportunity possible to enhance the viewing of the game through technological innovations,” he stated. “People at the networks have tried this sort of innovation before, but the technology of trying what is now being rumored is extremely complex.”

It was actual, although: A puck that glowed blue on TV and picked up a purple path behind it at excessive speeds. Shortly after FoxTrax debuted, a May 1996 Popular Mechanics article broke down the way it labored: An ordinary puck was minimize in half, hollowed out, fitted with a “circuit board about the size of a silver dollar,” and outfitted with 20 infrared emitters.

This was augmented by sensors positioned above and across the rink to find out the puck’s pace and place, whereas 4 Silicon Graphics workstations within the manufacturing truck had been tasked with dealing with the precise visible results. A complicating issue was the battery expertise of the time, as every FoxTrax puck may solely run for 10 minutes, requiring Fox to convey 50 of them for its debut on the 1996 NHL All-Star Game.

Watching FoxTrax in action at present, it does not learn as significantly obtrusive however was largely criticized by sports activities media on the time, and subsequently, it was ditched earlier than the NHL bundle’s 1998 transfer to ABC.

Lumix G9 II Review: A Great Upgrade for Professional Wildlife Photography

Despite not having a fan, the G9 II performs well in terms of overheating. This is because smaller sensors produce less heat. The previous model, the S5 II, could only record for 30 minutes in 6K mode, but the G9 II has no such limitations. To test its performance under extreme conditions, the camera was placed in a non-air-conditioned space with an ambient temperature of around 80 degrees Fahrenheit, and various video modes were tested.

In most common resolutions and framerates, the G9 II handles the workload without any issues. It can keep running until the battery dies, which is around 90 minutes with a full charge. Only at the highest resolutions and framerates does overheating become a possibility. After continuous recording, the grip and viewfinder of the camera become uncomfortably hot, and eventually, the camera shuts down to cool down.

The G9 II managed to run for 54 minutes at the maximum 5.8k resolution before overheating. It also performed well at 4K 60, running for a respectable 50 minutes. However, in the case of 4K 120, the camera could only sustain recording for 19 minutes before shutting down. However, in real-world scenarios, 120 FPS is rarely needed for more than a few seconds at a time, so this limitation may not be a significant issue. If you require better cooling, consider upgrading to the GH6 model.
