Computer sales and service

2019 was a record year for on-site technology projects, with 511 projects completed in Buffalo, Rochester, and Erie, PA.

Some of the 51 different national vendors we provided service for included: Acuative, Ammacore, Atlanta Network Systems, Concert Technologies, Core Technology Solutions, High Wire Networks, InGenius Solutions, KeyMe, Nationwide Fixture Installations, Level 10, Navco, Netcom USA, Netview, NSCglobal, OSBT, Park Place Technologies, Presidio, Randstad Technologies, Single Digits, Source Support and Trextel.

In addition to on-site computer service, we continue to provide web-site hosting with email and domain name registration. Computer repairs and upgrades were performed in our office at 1325 Millersport throughout the year.

We’re continually evaluating and upgrading our timing equipment to reach the ultimate goal of 100% reads with 100% inliers (3 or more reads from each chip passing.)

• June 2019: Our inventory of ChipCards have been upgraded to the larger CR100 (99x67mm) card. Larger ChipCards provide greater visibility than the CR80 (86x54mm) ChipCards. The larger cards allow the use of longer RFID chips, including the Alien ALN-9740 and Smartrac DogBone.
• July 2019: We now have a high efficiency 1000-watt inverter, suitable for running the laptop and two LCD monitors all day from a car battery. This inverter eliminates the need for a noisy generator.
• August 2019: New Logitech C9000 camera provides 1600×1200 (2mp) resolution using a wide angle glass lens for sharper images.
• September 2019: 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 Alien ALN-9740 tags using the higher performance Alien Higgs4 chip.
• October 2019: In addition to the 6dbi circular patch and 14dbi Yagi antenna, we have added a 8.5dbi linear antenna. The linear antenna provides the widest field of view, optimizing the use of quadratic regression by picking up more reads at the edges of the field of view. When combined with other antennas, CrossMgrImpinj can optimize between antenna selection, choosing the antenna with the most chip reads.
• November 2019: The reliable Impinj R220 reader has been replaced with a higher performance Impinj R420 reader using the latest 6.2.1 firmware. While the R220 can perform up to 500 chip reads per second, the R420 offers additional chip reader modes that can read up to 1500 chips per second.

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

• 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.
•  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.
• July 2018: CrossMgrVideo software has been improved with more features for recording and reviewing finish line photos.

Comparison of RFID chip signal strength (RSSI) data points along with curves generated by quadratic regression from the same data. With only 3 chip reads, QR can closely estimate the the signal strength curve for a chip and determine its time in front of the antenna.

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 375 on-site service projects completed in Buffalo and Rochester.

A total of 50 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. These projects required 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.
