Acoustic Pulse Recognition technology Input Method Mechanical Positional Accuracy Resolution Accuracy Touch Activation Force Controller Optical Light Transmission Environmental Chemical Resistance Surface Durability Expected Life Finger, finger nail, solid stylus or gloved hand (cloth, leather or rubber) activation 1% maximum error Touchpoint density is based on controllers resolution of 4096 x 4096 Typically 2 to 3 ounces (55 to 85 grams) Board: USB 1.1 90% +/- 5% The touch activation area of the touchscreen is resistant to chemicals such as: ● Acetone ● Toluene ● Methy ethyl ketone ● Isopropyl alcohol ● Methyl alcohol ● Ethyl Acetate ● Ammonia-based glass cleaners ● Gasoline ● Kerosene ● Vinegar Surface durability is that of glass, Hohs' hardness rating of 7. No known wear-out mechanism, as there are no layers, coatings or moving parts. APR technology has been operationally tested to more than 50 million touches in one location without failure, using a stylus similar to a finger. 20 Appendix B Technical specifications
