Abstract:
An electronic device, physically protected from shock, comprising:a signal conditioning circuit, having an input and an output; said signal-conditioning circuit comprises: a voltage regulator, having an input and an output; a first capacitor operably connected to said voltage regulator's input; a second capacitor operably connected to said voltage regulator's output; a diode, operably connected to said voltage regulator's input, for reverse voltage protection; and a surge-suppressing diode imposed between the output of said signal conditioning circuit and an electrical ground, wherein said signal-conditioning circuit enables provision of filtered and regulated power to said electronic device; a timing source operably connected to said signal-conditioning circuit; an analog-to-digital converter (ADC), operably connected to said signal-conditioning circuit; a trigger for initiating events, operably connected to said signal conditioning circuit, said timing source, and said ADC; a controller, operably connected to each of said signal conditioning circuit, said ADC, said timing source, and said trigger; and a non-volatile memory, operably connected to each of said controller and said signal conditioning circuit, wherein said electronic device acquires data, retains at least portions of said data in said non-volatile memory, and processes said data for output during events subjecting the electronic device to shock, power disruption, or both.
