Abstract
A system for detecting liquid on a battery or on an electronic device connected with the battery is presented. The battery has an electrical contact for transferring current from the battery to the electronic device. The system includes a sensor for detecting liquid on the battery or on the electronic device and sensor circuitry connected with the sensor. The sensor circuitry prevents current from flowing through the electrical contact of the battery upon detecting liquid.
Claims20
An electronic device comprising:
- a housing having a first contact;
- a battery having a second contact connected with the first contact;
- a sensor for detecting liquid;
- and
- sensor circuitry in communication with the sensor, wherein the sensor circuitry prevents current from flowing between the first and second contacts upon the sensor detecting the liquid.
A system for detecting liquid on a battery or on an electronic device connected with the battery, the battery having an electrical contact for transferring current from the battery to the electronic device, the system comprising:
- a sensor for detecting the liquid on the battery or on the electronic device;
- and
- sensor circuitry connected with the sensor, wherein the sensory circuitry prevents current from flowing through the electrical contact of the battery upon the sensor detecting the liquid.
A method for detecting liquid on a battery, comprising:
- detecting the presence or absence of liquid on a surface of the battery using a sensor;
- and
- preventing current from flowing through an electrical contact of the battery upon detecting the presence of liquid.
