Capacitive sensors work by detecting the change of capacitance introduced by the finger touching near the electrode. Such change is so small that detecting it unambiguously is challenging, and has ...

Figure 7 provides the typical design flow for implementing capacitive sensing. Firmware (F/W) Development, Tuning, and Production Fine Tuning are the critical phases in the life cycle of a ...

• Trapped acoustic resonance is most simply described with an analogy: the ringing of a bell. • Microprocessors control the frequency of the mechanical resonance and monitors its decay. • A thicker ...

Engineers developing heavy equipment such as tractors, cranes, wood chippers, and construction equipment need to include incline sensors and indicators—both to ensure that workers do not operate the ...

A 1-op-amp circuit for processing the signal from a piezoelectric accelerometer. Accelerometers are used in instrumentation applications to measure a change in velocity with respect to time or an ...
