Abstract:
1. An information handling system comprising: a free fall sensor configured to detect movement in the information handling system; an amplifier and sampling circuit in communication with the free fall sensor, the amplifier and sampling circuit configured to sample data signals from the free fall sensor based on an initial sampling signal and based on a variable sampling signal; a sampling data analyzer in communication with the amplifier and sampling circuit, the sampling data analyzer configured to compare a magnitude of a sampled data point to a predetermined magnitude and to output an alert signal when the magnitude of the sampled data point is below the predetermined magnitude; and a sampling clock generator in communication with the amplifier and sampling circuit, the sampling clock generator configured to send the initial sampling signal to the amplifier and sampling circuit, and to send the variable sampling signal to the amplifier and sampling circuit in response to the alert signal, wherein the variable sampling signal has different frequencies and different durations that vary between different pairs of pulses of the variable sampling signal.
