Actuating mechanism and electronic device
11466710 · 2022-10-11 · ·

An actuating mechanism includes a target, a smasher, an elastic component, and a blocker. The smasher is movably disposed at a side of the target. The elastic component is configured to provide an elastic force to drive the smasher to move toward the target. The blocker is movably disposed corresponding to the smasher. When the blocker contacts the smasher, the blocker clamps the smasher. When the blocker is moved to a position where the clamping to the smasher is released, the smasher is driven by the elastic force to move toward and smash the target. An electronic device is also provided.

Chip tampering detector

A chip tampering detector is disclosed. The chip tampering detector includes a plurality of resistor-capacitor circuits. Each resistor-capacitor circuit includes a capacitor having a planar area that covers a sensitive area of an integrated circuit of the chip. The resistor-capacitor circuits can be probed with an input signal to generate output signals. The output signals can be measured to determine respective time-constants resistor-capacitor circuits. Tampering with a chip can alter the capacitance of a capacitor covering a sensitive area. Accordingly, a significant change of a time-constant of one or more of the resistor-capacitor circuits can be used to detect chip tampering.
