Abstract
Described is a method wherein a computer terminal is coupled to a power supply through a docking arrangement. The docking arrangement includes a protection circuit. A current supplied to the computing terminal is detected. When the current is greater than a predetermined value, the computer terminal is decoupled from the power supply. After the computer terminal is decoupled from the power supply, the computer terminal is recoupled to the power supply, and the method repeats beginning with detecting the current supplied to the computing terminal.
Claims23
A method, comprising:
- (a) coupling a computer terminal to a power supply through a docking arrangement, the docking arrangement including a protection circuit;
- (b) detecting a current supplied to the computing terminal;
- (c) when the current is greater than a predetermined value, decoupling the computer terminal from the power supply;
- (d) after step (c), recoupling the computer terminal to the power supply;
- and
- (e) performing steps (b), (c) and (d), wherein a time between subsequent performances of step (b) increases after each performance of step (e).
A docking arrangement, comprising:
- a cradle for receiving a computing terminal;
- a power supply providing a current to the terminal;
- a protection circuit detecting a current supplied to the computing terminal when the terminal is coupled to the power supply via the cradle,
- wherein, when the current is greater than a predetermined value, the protection circuit decouples the terminal from the power supply, and
- wherein the protection circuit recouples the terminal to the power supply to periodically monitor the current after recoupling, wherein a time period between subsequent instances of recoupling and monitoring increases as the protection circuit continues to detect that the current is greater than the predetermined value.
A system, comprising:
- a docking arrangement for coupling a power supply to a computing terminal, the power supply supplying power to the computing terminal;
- and
- a circuit detecting a current being supplied to the computing terminal,
- wherein, when the current is greater than a predetermined level, the circuit decoupling the power supply from the computing terminal for a predetermined time, wherein, after the decoupling, the circuit coupling the power supply to the computing terminal to monitor the current wherein the predetermined time increases as the circuit continues to detect that the current is greater than the predetermined level.
