Title: Innovations by Joshua Zazzera
Introduction
Joshua Zazzera is an accomplished inventor based in Phoenix, AZ. He holds a total of 6 patents that showcase his expertise in the field of haptic technology. His work primarily focuses on enhancing user experience through innovative feedback mechanisms.
Latest Patents
One of his latest patents is related to the braking control of haptic feedback devices. In this invention, a controller obtains a back electromotive force (BEMF) signal associated with a haptic feedback component. The BEMF signal is generated by the movement of the haptic feedback component. The controller determines a time length for the BEMF signal to cross an amplitude-based window and subsequently calculates a braking amplitude for a control signal to reduce the energy level of the haptic feedback component. This innovative approach allows for more precise control of haptic feedback.
Another significant patent focuses on haptics audible noise reduction. This invention proposes innovative techniques to design and generate haptic waveforms that reduce or eliminate audible noises produced by a haptic actuator during operation. A haptic controller composes a voltage waveform at a resonant frequency of the haptic actuator, generating a corresponding control signal. By including a ramp-down portion in the voltage waveform, the current flowing within the actuator is gradually reduced before entering a high impedance state, effectively minimizing audible noise.
