Introduction to Polygon Tech Polygon Tech was found to research and develop

wireless test equipment with the latest technologies,such as URLLC (ultra reliable low latencycommunications),Witricity, etc.

Polygon Tech’s product focuses to address the need ofthe industrial testing & measurement market

Polygon’s first generation wireless acquisition system isin shipment to our customers.

Polygon is planning to open a R&D office in China. Wehave hired two engineers so far and will grow the teamrapidly.

Product - System Introduction

The URLLC system is design for contact-free transfer of strain gage signal at high-speed rotation machine to a stationarydata acquisition receiver. Thecommunication latency is design for afixed latency of 0.5ms. System consists of:1. System Hardware: Low distortion, low

1. System Hardware: Low distortion, lownoise strain gage amplifiers, an URLLCreal-time wireless transmitter , awireless receiver and a data recovery,display and storage system.

2. Data acquisition software3. Post-Data processing software

Product-System Hardware

Ultra-reliable in the industrial environment

Clock-synchronized TX & RX

Fixed Latency at 0.5ms or less

System is extendable to 80 channels

Transmitter Remote Control GainGain

Calibration

Enable Zeroing/Re-Zeroing

When the local acquisition unit is turned off, the remote gage amplifier will beturned off automatically to save power.

Transmitter Remote Status Reporting Can report 16 different status

Low battery power

Temperature & Humidity ( used at post-data processing to compensate the straingage temperature variation.)
