Abstract
Abstract The electronic device powering system enables a battery powered device to power another device needing power while also powering itself. The accessory power connector (102) makes a connection before breaking it by a spring contact (110) that is more flexible in one end (111) than the other (112). This allows the less flexible end (112) to force the internal power connector (104) in the electronic device to break its connection.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
140 words
An electronic device powering system, a first electronic device being powered by a second electronic device having a battery, electronic components, an internal powering mode, an external powering mode, and accepting external powering means, the electronic device powering system comprising: a first flexible contact coupled to the battery; a second contact coupled to the electronic components and coupled to the first flexible contact in the internal powering mode; and a third, flexible contact located in the external powering means, the third contact having a first protrusion portion coupled to the first flexible contact in the external powering mode and a second protrusion portion coupled to the second contact in the external powering mode, the first protrusion portion being less flexible than the second protrusion portion, thus forcing the first contact away from the second contact in the external powering mode.
Claim 2
Dependent Claim
140 words
An electronic device powering system, a first electronic device being powered by a second electronic device having a battery, electronic components, an internal powering mode, an external powering mode, and accepting external powering means, the electronic device powering system comprising: a first flexible contact coupled to the battery; a second contact coupled to the electronic components and coupled to the first flexible contact in the internal powering mode; and a third, flexible contact located in the external powering means, the third contact having a first protrusion portion coupled to the first flexible contact in the external powering mode and a second protrusion portion coupled to the second contact in the external powering mode, the first protrusion portion being less flexible than the second protrusion portion, thus forcing the first contact away from the second contact in the external powering mode.
Claim 3
Dependent Claim
29 words
The powering system of claim 1 wherein the external powering means is a connector coupled to a cable that supplies power from the battery to the first electronic device.
Claim 4
Dependent Claim
150 words
An electronic device power system, a first electronic device being powered by a second electronic device having a battery, electronic components, an internal powering mode, an external powering mode, and accepting external powering means, the electronic device power system comprising: a first flexible contact coupled to the battery; a second contact coupled to the electronic components and coupled to the first flexible contact in the internal powering mode, the second contact coupled under the first flexible contact; and a third, flexible, substantially U-shaped contact located in the external powering means, the third contact having a first protrusion portion coupled to the first contact in the external powering mode and a second protrusion portion coupled to the second contact in the external powering mode, the first protrusion portion being less flexible than the second protrusion portion, thus forcing the first contact down from the second contact in the external powering mode.
Claim 5
Dependent Claim
150 words
An electronic device power system, a first electronic device being powered by a second electronic device having a battery, electronic components, an internal powering mode, an external powering mode, and accepting external powering means, the electronic device power system comprising: a first flexible contact coupled to the battery; a second contact coupled to the electronic components and coupled to the first flexible contact in the internal powering mode, the second contact coupled under the first flexible contact; and a third, flexible, substantially U-shaped contact located in the external powering means, the third contact having a first protrusion portion coupled to the first contact in the external powering mode and a second protrusion portion coupled to the second contact in the external powering mode, the first protrusion portion being less flexible than the second protrusion portion, thus forcing the first contact down from the second contact in the external powering mode.
