Abstract
An electronically controlled, motor-driven device is able to issue locally perceptible acoustic alerts by causing the electric motor to vibrate, which in embodiments can include vibrations at a resonant frequency of the device. Embodiments encode information relevant to the alert as amplitude and/or frequency modulations of the acoustic vibrational alerts. The motor can be an AC motor or a DC motor. In embodiments, the motor-driven device is an electronically controlled valve actuator or electronically controlled pump. The device can be in communication with a remote monitoring station, or the electronic controller can be remotely located.
