چکیده
The purpose of this application note is to describe the best design practices when developing capacitive touch applications in noisy environments. This application note will begin by defining the problems caused by noise, and explain how that noise typically affects systems. Hardware guidelines will then be provided to help maximize the natural signal-to-noise ratio (SNR) of the application. Software techniques are then covered to describe some of the common methods used to filter a sensor’s signal to increase the SNR further, and then to make a decoding decision based on the behavior of the capacitive sensor.

متن کاملMapping of McGraw Cycle to RUP Methodology for Secure Software Developing
Designing a secure software is one of the major phases in developing a robust software. The McGraw life cycle, as one of the well-known software security development approaches, implements different touch points as a collection of software security practices. Each touch point includes explicit instructions for applying security in terms of design, coding, measurement, and maintenance of softwar...
متن کاملAn Alternative Stability Proof for Direct Adaptive Function Approximation Techniques Based Control of Robot Manipulators
This short note points out an improvement on the robust stability analysis for electrically driven robots given in the paper. In the paper, the author presents a FAT-based direct adaptive control scheme for electrically driven robots in presence of nonlinearities associated with actuator input constraints. However, he offers not suitable stability analysis for the closed-loop system. In other w...
متن کاملSoloTouch: A Capacitive Touch Controller with Lick-based Note Selector
This paper describes the design of a guitar-inspired, pocketsized controller system SoloTouch. SoloTouch consists of a capacitive touch trigger, and an automated note selector program. Requiring only one finger, the touch trigger allows intuitive execution of both velocity sensitive notes and aftertouch messages. The automated note selector program selects consecutive consonant notes from prepr...
