Aspects of the disclosure provide an apparatus having a first connector and a signal processing circuit. The first connector is configured to receive a second connector so that connecting terminals at respective portions of the first and second connectors are coupled together. The signal processing circuit is configured to generate a first output signal at a first amplification gain, determine a first load resistance value at a first connecting terminal of the second connector that is configured to receive the first output signal when coupled to the first connector, and set the first amplification gain based on the first load resistance value.

Apparatus for and method of generating output signal based on detected load resistance value

To limit motion in an electromechanical system, an input signal is filtered using an adaptive filter, such as an infinite impulse response filter, to yield a predicted motion, and the input signal is attenuated by an amount controlled by the predicted motion. The filtering may further yield a predicted temperature, and the amount of attenuating may be further controlled by that temperature. Components of the input signal at selected frequencies may be removed, and a portion of the input signal from which the components have been removed may be mixed with a portion of the input signal from which components have not been removed. The removing of components at selected frequencies may include applying a notch filter, and the two portions may be equalized. phase-adjusting the unfiltered portion to account for phase delay introduced by the notch filter. The notch filter may operate at a resonant frequency of the system.

Detection of an anomalous event in an electronic apparatus includes detecting accelerations acting on the electronic apparatus, establishing a normal-mode range of accelerations that corresponds to normal operation of the apparatus, and detecting the anomalous event when a level of acceleration of the electronic apparatus exits the normal-mode range and remains outside the normal mode range for more than a defined duration. The method includes displacing the normal-mode range toward a current level of acceleration of the electronic apparatus while the level of acceleration remains outside the normal-mode range. Additionally, the normal-mode range is increased toward a maximum size while the level of acceleration remains outside the normal-mode range, and is decreased toward a minimum size while the level of acceleration is within the normal-mode range.
