Patent ID: 8433433

Claim:
A system for determining whether an ultrasonic horn is aligned with an anvil of an ultrasonic welding system, comprising: first and second accelerometer sensors being disposed at first and second positions, respectively, on a bracket coupled to the anvil, the first and second accelerometer sensors generating first and second signals, respectively, indicative of first and second accelerations, respectively, of the first and second positions, respectively, in response to the ultrasonic horn vibrating and contacting the anvil; and a microprocessor operably coupled to the first and second accelerometer sensors receiving the first and second signals, the microprocessor determining a difference between an amplitude of the first signal at a first time and an amplitude of the second signal at the first time, the microprocessor storing a first identifier value in a memory device indicating that the ultrasonic horn is aligned with the anvil in response to the difference between the amplitude of the first signal and the amplitude of the second signal being less than or equal to a threshold value.
