MUMBAI, India, June 30 -- Intellectual Property India has published a patent application (202441102484 A) filed by Qualcomm Incorporated on December 24, 2024, for Excursion Protection For Linear Resonant Actuators.
Inventors include Venkata Mohana Vamsi Voora; Hari Vasudevan; and Shyama P.
The application for the patent was published on June 26, 2026, under issue no. 26/2026.
Abstract: ABSTRACT A device includes a memory and one or more processors coupled to the memory. The memory is configured to store, in a voltage buffer, voltage values representing samples of a control signal for a linear resonance actuator (LRA). The one or more processors are configured to use a model to estimate, based on a set of multiple voltage values from the voltage buffer, a set of multiple displacement values representing predicted motion of the LRA. The one or more processors are configured to determine a predicted gain value based on a previous gain value, a displacement threshold associated with the LRA, and the set of multiple displacement values. The one or more processors are configured to generate an output voltage value based on a voltage value of the set of multiple voltage values and a gain value, where the gain value is based on the predicted gain value.
