Abstract
A status monitoring system includes a status sensor configured to monitor a status of an electronic circuit. If the status monitoring system detects a status that exceeds a threshold, the status monitoring system records the details of the event on the electronic circuit. The status monitoring system operates in a low-power power mode during transit from a manufacturing facility to an installation location.
Claims22
A method for monitoring a status of a printed circuit board (PCB), comprising:
- in a low-power mode of the PCB, providing power to a status sensor from a power source located on the PCB, wherein the status sensor includes a strain gauge integrally formed below an outer surface of the PCB to measure internal stress or strain experienced by the PCB;
- in the low-power mode and using the status sensor, detecting an event impacting the PCB;
- and
- recording details of the event at the PCB.
A printed circuit board (PCB), comprising:
- a base;
- a status sensor located at the base, wherein the status sensor includes a strain gauge integrally formed internally within a body of the PCB to measure internal stress or strain experienced by the PCB;
- a low-power power source providing power to the status sensor;
- and
- a memory and processor connected to the status sensor, the memory including instructions which cause the processor to:
- in low-power mode, detect an event impacting the PCB using the status sensor;
- and
- record details of the event in the memory.
A method for monitoring a status of a printed circuit board (PCB), comprising:
- in a low-power mode, monitoring a status sensor connected to a base of the PCB;
- detecting an event associated with transit of the PCB, the event including a status magnitude that is greater than a threshold status magnitude;
- and
- based on the event, recording the status magnitude on the PCB, wherein the status magnitude detected by the status sensor includes an internal strain magnitude of the PCB associated with the transit of the PCB, wherein the internal strain magnitude is measured by a strain gauge deposited as part of a layer of the PCB.
