Abstract: Electronic devices may be accidentally exposed to liquid during operation. To detect liquid intrusion events, an electronic device may be provided with one or more electronic liquid contact sensors. The liquid contact sensors may have electrodes. Control circuitry may make measurements across the electrodes such as resistance and capacitance measurements to detect the presence of liquid. Liquid contact sensor data may be maintained in a log within storage in the electronic device. The liquid contact sensor data can be used to display information for a user of the electronic device or can be loaded onto external equipment for analysis. Liquid contact sensor electrodes may be formed from metal traces on substrates such as printed circuits, from contacts in a connector, from contacts on an integrated circuit, or from other conductive electrode structures.

Abstract: A series pass circuit conducts a pass current between a first side and a second side. A power source is coupled to the first side, while a capacitor is coupled to the second side. A system component whose power supply input is coupled to the capacitor may exhibit pulse-type activity. A control circuit increases the resistance to the pass current, in the series pass circuit, in accordance with a reporting signal that indicates whenever the system component is more active or less active. Other embodiments are also described and claimed.
