APPARATUSES, SYSTEMS, AND METHODS FOR REDUCING POWER TO PORTS OF ELECTRONIC DEVICES

摘要

Methods, apparatuses and systems for reducing or selectively terminating the power supplied to or the voltage present at the ports of electronic devices are disclosed. Methods, apparatuses and systems for reducing or terminating the power supplied to and, thus, the voltage across electrical contacts of one or more ports of a portable electronic device when the port is not in use may be effected in a variety of ways and may prevent corrosion or other moisture-induced damage to each port, and to the electronic device of which the port is a part.

主权项

1. A voltage control element comprising:
a device detector that detects whether a port of an electronic device is:
connected to a device; ornot connected to a device; a power controller that:
provides a normal voltage state for the port in response to the device detector determining that the port is connected to a device;provides a reduced voltage state for the port in response to the device detector determining that the port is not connected to a device.
