Abstract:
An information handling system includes a free fall sensing system having an amplifier and sampling circuit, a sampling data analyzer, a sampling clock duration controller, and a sampling clock generator. The amplifier and sampling circuit is configured to sample data signals from the free fall sensor based on an initial sampling signal and based on a variable sampling signal. The sampling data analyzer is configured to compare a magnitude of sampled data point to a predetermined magnitude, to output an alert signal when the magnitude of the sampled data point is below the predetermined magnitude. The sampling clock duration controller is configured to vary a duration and a frequency of a sampling signal control in response to the alert signal. The sampling clock generator is configured to send a variable sampling signal to the amplifier and sampling circuit in response to the variation of the duration and the frequency of the sampling signal control.
