Abstract: A method may include receiving an input signal, generating a baseline signal based on the input signal, generating a corrected input signal by subtracting the baseline signal from the input signal, determining a threshold level change of the input signal when the corrected input signal exceeds a level change threshold, and responsive to the threshold level change, updating the baseline signal to the level change threshold.

Abstract: A method for determining sensor parameters of an actively-driven sensor system may include performing an initialization operation to establish a baseline estimate of the sensor parameters, obtaining as few as three samples of a measured physical quantity versus frequency for the actively-driven sensor system, performing a refinement operation to provide a refined version of the sensor parameters based on the as few as three samples, iteratively repeating the refinement operation until the difference between successive refined versions of the sensor parameters is below a defined threshold, and outputting the refined sensor parameters as updated sensor parameters for the actively-driven sensor system.

Abstract: Embodiments described herein relate to methods and apparatuses for controlling an operation of a vibrational output system and/or an operation of an input sensor system, wherein the controller is for use in a device comprising the vibrational output system and the input sensor system. A controller comprises an input configured to receive an indication of activation or de-activation of an output of the vibrational output system; and an adjustment module configured to adjust the operation of the vibrational output system and/or the operation of the input sensor system based on the indication to reduce an interference expected to be caused by the output of the vibrational output system on the input sensory system.

Abstract: A device may include an input for receiving information communicated from a host to the device and a controller configured to recover a device reference clock on the device, the device reference clock proportional to a host reference clock of the host, when clock signaling from the host to the device is unavailable. The controller may recover the device reference clock by measuring a ratio between the host reference clock and the device reference clock of the device by monitoring, with the device, host start-of-frame markers communicated from the host to the device via the input, creating a recovered reference clock based on the measured ratio, and creating local start-of-frame markers that are phase locked with the host start-of-frame markers based on the recovered reference clock.A method for generating a not-yet (NYET) signal in a recovered reference system for recovering a device reference clock on a device, wherein the NYET signal indicates that the device is not yet ready for transition into a low power mode, in order to improve a quality of a recovered reference clock representative of a host reference clock of a host communicatively coupled to the device, may be provided. The method may include detecting receipt of start-of-frame markers from the host to the device, responsive to detecting receipt of the markers, determining whether a condition for NYET generation is being met, responsive to the condition for NYET generation being met, generating the NYET signal to cause the host to continue generating the markers, and responsive to the condition for NYET generation not being met, causing the device to generate an acknowledge signal for transition of the device into the low power mode.
