摘要： An electronic device has a chassis, and a printed wiring board (PWB) having a hole. A fastener is installed in the hole thereby securing the PWB to the chassis. A pair of conductive traces is formed in the PWB. A cap, being an amount of conductive glue, covers a part of the fastener and fills an electrically insulating gap between the two traces, to thereby form a conductive path that connects the two traces. A sensing circuit is coupled to the traces, to detect a change in impedance of the path and signal a tamper event alert. Other embodiments are also described and claimed.

摘要： Embodiments disclosed herein provide systems, devices, and methods for detecting the occurrence of consumer abuse events in electronic devices. In one embodiment, a system includes one or more sensors coupled to an abuse detection sub-system for detecting the occurrence of an abuse event, wherein upon detecting an abuse event, a record of the abuse event is stored by the abuse detection sub-system. The system further provides a communication interface configured to provide a first mode of diagnostic communication and a second mode of non-diagnostic communication through a common input/output port. When using a diagnostic device, the diagnostic mode of communication may be enabled, thus allowing the diagnostic device to access consumer abuse event data stored by the abuse detection sub-system.
