Abstract
Aspects of shutdown control of a device in the presence of moisture are described. In one embodiment, a moisture detection signal is received from a moisture detector. In turn, certain parameters associated with the moisture detector are identified. For example, the location of the moisture detector may be identified. Additionally or alternatively, a probability for damage to the device, based on the location of the moisture detector, may be identified. An evaluation of the moisture detection signal and the identified parameters is performed. Based on the evaluation, one of various power down procedures for the device may be initiated. In certain cases, a quick power down reaction for one or more subsystems of the device, in response to the detection of moisture, may prevent damage to the device.
Claims20
A method, comprising:
- receiving, from a moisture detector associated with a mobile communication device, a moisture detection signal;
- identifying a parameter associated with at least one of the moisture detector or the moisture detection signal;
- and
- initiating, in response to the identified parameter, a power down procedure to power down at least a portion of the mobile communication device.
A mobile communication device, comprising:
- a moisture detector that detects a relative level of moisture;
- a host controller that coordinates operation of the mobile communication device;
- and
- a power controller that:
- coordinates a supply of power from a battery to subsystems of the mobile communication device;
- identifies a parameter associated with at least one of the moisture detector or a moisture detection signal received from the moisture detector, in response to receipt of the moisture detection signal;
- and
- based on the identified parameter, disconnects the supply of power from the battery.
A method, comprising:
- receiving a moisture detection signal;
- identifying, with a controller, a parameter associated with at least one of the moisture detection signal or a moisture detector associated with the moisture detection signal;
- and
- based on the identifying, initiating a power down procedure to power down at least a portion of a mobile communication device based on a probability for damage to the mobile communication device.
