  • Multi-prong power tip adaptor
    Patent number: 8821199
    Abstract: Consolidated power tips allow a power adaptor to be connected to disparately sized input ports of electronic devices. The consolidated power tips may be sized to balance insertion and pull-out forces for the disparately sized input ports. Deformable members may be added to the consolidated power tips for more desirable insertion and pull-out forces and improved electrical contact. For input ports with different electrical requirements, a mode selector may be added to the consolidated power tip to select between the electrical requirements of the different input ports. The consolidated power tips may be combined into a multi-prong power tip. The multi-prong power tip allows users to interface with a large number of disparate devices without changing power tips.

  • Multi-sleeve power tips
    Patent number: 8550827
    Abstract: Consolidated power tips allow a power adaptor to be connected to disparately sized input ports of electronic devices. The consolidated power tips may be sized to balance insertion and pull-out forces for the disparately sized input ports. Deformable members may be added to the consolidated power tips for more desirable insertion and pull-out forces and improved electrical contact. The consolidated power tips may be combined into a multi-sleeve power tip. Each sleeve comprises a device interface for a different set of input ports. Unused sleeves may be retracted into the housing of the power tip. Manual or automatic extension mechanisms may be provided for extending the device interfaces from the housing. The multi-sleeve power tip allows users to interface with a large number of disparate devices without changing power tips.
