Latest Patents

One of Calvin's latest patents is focused on control system methods and apparatus for inductive communication across an isolation barrier. This invention improves control apparatus and methods that transfer information between devices, such as controllers and field devices. The technology utilizes a modulator that generates a pulse width modulated (PWM) signal containing information to be transferred from the controller to the field device. A transformer or other inductive device is employed to transfer the PWM signal across the isolation barrier, where it is demodulated to analog form for application to the field device. Additionally, information transferred from the field device back to the controller can be sent using an amplitude modulated (AM) signal, utilizing a fixed duty cycle output of the modulator that generates the PWM signal.
