Abstract:
A method for recording data on a recorder that experiences physical shock, power disruption, or both, comprising:conditioning a signal, said conditioning a signal comprising regulating voltage via a voltage regulator having an input and an output, providing a source of energy via a first capacitance and a second capacitance operably connected to said regulator's input and output, respectively, suppressing voltage spikes via a diode operably connected to said voltage regulator's output of said signal conditioning circuit and electrical ground, and providing one way isolation via a diode imposed between the input of said signal conditioning circuit and the power connection, wherein said signal-conditioning provides filtered and regulated power to said recorder; powering components of a digital recorder using said conditioned signal; establishing and providing a clock signal; converting input analog signals into digital form as bytes of data; separating said bytes into a most significant byte and a least significant byte; controlling operations on said bytes using said clock signal and a trigger signal; serially transmitting said separated bytes; storing said separated bytes in non-volatile memory; recombining said separated bytes; and outputting said recombined bytes, wherein said method provides a reliable and efficient means for acquiring, recording, and outputting data obtained while testing in unfavorable environmental conditions.
