I-Point operates as a variable resistor, providing rate control in various form factors. In the case of I-Point, there are four variable resistors that operate to provide directional control in four quadrants. By producing different resistances, which equate to different voltages at the analogue to digital converter, many vectors, or directions, are produced. Although cost and reliability are critical for mass market control applications, I-Point's performance characteristics are exceptional. This level of accuracy and performance exceeds that required by all but a very few mission critical applications.
Form factor is another important consideration.
VTI offers a complete documentation package that describes Varatouch Technology, including I-Point, in great detail. Please contact our Sales and Marketing department for more information. Patents have been awarded for key aspects of I-Point technology. Additional patents covering I-Point are applied for. It is anticipated that supplementary patents will be applied for in the future, both domestically and internationally.
