POWER SUPPLY EQUIPMENT UTILIZING INTERCHANGEABLE TIPS TO PROVIDE POWER AND A POWER INDICATION SIGNAL TO AN ELECTRONIC DEVICE
First Claim
1. Power supply equipment comprising:
- an adapter to convert power from a power source, external to the adapter, to DC power for powering an electronic device which is external to the power source and the adapter;
a cable having proximal and distal ends, the proximal end being electrically coupled to the adapter and the distal end terminating in a connector;
a power indication circuit which generates a power indication signal for use by the electronic device to control power drawn by the electronic device; and
a tip which includes;
an input connector which is detachably mateable to the connector, andan output connector which is detachably mateable to the electronic device,wherein the tip provides the DC power and the power indication signal to the electronic device, andwherein the output connector has a shape and a size dependent on the shape and size of a power input opening of the electronic device.

Abstract
Power supply equipment includes an adapter which converts power from a power source to DC power for powering an electronic device. The power supply equipment includes circuitry which produces a power indication signal for use by the electronic device to control power drawn by the electronic device. A cable, which is electrically coupled to the adapter, has a connector at its distal end. The power supply equipment further includes a tip which has an input connector and an output connector. The input connector of the tip is detachable mateable to the connector on the distal end of the cable. The output connector of the tip is detachably mateable to the electronic device. The tip output connector has a shape and size dependent on the shape and size of a power input opening of the electronic device. The tip provides the power indication signal, as well as the DC power, to the device.
