Abstract
An advertising article with an automatically activated indicator assembly attached to the article including a piezoelectric sensor, a printed circuit board including a triggerable signal generator, and an LED or speaker. The piezoelectric sensor is attached to the advertising article such that it is responsive to mechanical force experienced by the advertising article during normal use, and, in response to such force, produces an output level sufficient to trigger the signal generator which in turn supplies a signal to activate the LED or speaker which is connected thereto. The signal generator includes device control circuitry for providing a battery-saving sleep state.
