For 2018, there have been upgrades to the CrossMgr/Impinj RFID timing system that provide improved quality results.

•  April 2018: CrossMgrImpinj software was upgraded to support quadratic regression (QR) analysis. This allows CrossMgr software to use 3 or more RFID chip times to calculate the time on the finish line with 1/100 second precision, yielding 6-inch accuracy at 34mph.  Prior to quadratic regression, CrossMgr used only the first time reported by an Impinj reader, resulting in finish times up to 10 feet before the finish line.  Since  Impinj RFID readers support up to 600 tags per second, individual tags can be read up to 20 times while passing the antenna, providing plenty of data to calculate a high precision time with very high confidence.
• May 2018: RANSAC (random sample consensus) processing logic was added to improve the results of quadratic regression analysis. RANSAC analysis eliminates spurious outlier data collected from the RFID chip reader due to signal reflection.
• June 2018: Support has been added for higher resolution cameras.
• CrossMgrVideo software has been improved with more features for recording and reviewing finish line photos.
• March 2018: We’ve added an ultra low light camera with an AR0130 sensor. This camera is so sensitive to light that it is used for photographing distant stars at night.
• July 2018: In addition to the Impinj H47 tags that use the Impinj Monza 4 RFID chip and True3D dual dipole antenna, we also have more sensitive Smartrac Dogbone tags using the higher performance Impinj Monza R6 chips. These chips provide improved performance when wet and also when moving above 30mph.

Comparison of RFID chip signal strength (RSSI) data points along with curves generated by quadratic regression from the same data.

Here are the results of research on selected available camera sensors. For lenses, the varifocal 5-50mm lens with an 8 to 80 degree field of view provides the widest range.  A 2.8-12mm lens with 28 to 130 degree field of view is another option.

For comparison, the human eye has a 2.97mm focal length with a 128 degree field of view.

Sony produces the IMX sensors. ON Semiconductor (formerly Aptina Research) produces the AR sensors. OmniVision produces the OV sensors.

2017 was a busy year, with over 375 on-site service projects completed in Buffalo and Rochester.

More than 20 different national service providers assigned us projects this year, including: Trextel, BLM Technologies, Concert Technologies, Netcom USA, Netview, BlackBox, Ammacore, Reliable IT, One Source Building Technology, nFrastructure, Randstad Technologies, Core Technology, CompuCom, Pomeroy, SourceSupport Services, Sequenza, HighWire Networks, Dimension Data, Presidio, Velocity Network Services and Vital Network Services.

These companies represent national brands, and relied on us to provide local service for their customers in a variety of industries. Many of these service projects involved testing and “turning-up” Internet and network connections, involving testing and troubleshooting network connections between routers, switches, servers and Internet providers.

In the hospitality market, we serviced Starbucks, Tim Hortons, Panera Bread, McDonalds, Checkers, Mortons Steak House, Hampton Inn,  and Embassy Suites.

Banking clients we serviced included: HSBC, M&T Bank, Key Bank and Citizens Bank.

In addition to providing on-site timing services in NY, PA and OH, we also provide remote support to timers using CrossMgr software and J-Chip RFID hardware in other locations.

For the Red Rock Time Trial in Las Vegas, Nevada, we provided remote support for CrossMgr to Danny Leberger from HIE Cycling.

For the The Guam Cycling Federation and Tour of Guam, we provided remote support to Matt Ellis for multiple races using J-Chip RFID hardware and CrossMgr software.

For Danny Matusczak in Florida, we provided remote support for new software created to link Race Director timing software with J-Chip RFID hardware.

Starting in 2016, we began using a new RFID timing system we developed and named ChipCard RFID timing. In addition to the J-Chip active timing system we have been using since 2012, our new ChipCard timing system provides a unique set of capabilities.

At the heart of this timing system is a durable new plastic ChipCard that is capable of being read 100,000 times and is rated with 50-year reliability.  Each ChipCard is assigned a number that can be matched to the the racers bib number, ensuring that every racer can be accurately identified.

The ChipCard is attached to the seatpost with a pair of hook and loop straps.  Attaching the ChipCard to the seatpost provides a consistent location on the bike that is 48″ from the front edge of the tire.

The ChipCard is read using an antenna mounted at the side of the road, allowing us to provide timing for any size finish.  The antenna is also offset 48″ from the finish line so that the chip time is calculated when the front edge of the tire is on the finish line. With two high gain antennas on one side of the road, no mat, cable or truss is needed on the road.

ChipCards are given to racers at no charge as part of our timing service.  Lost or missing chip cards can quickly and easily be replaced on race day, and cards can be tested anytime before a race starts.

The ChipCards are read using an Impinj RFID reader that can process up to 600 chips per second, allowing each chip to be read up to 20 times as it passes by the antenna. Using quadratic regression analysis, the chip timing software calculates the chip time with 1/100 second precision.
