Abstract: In one embodiment, a rechargeable battery pack can be configured to power an electronic device having a first battery. The rechargeable battery pack can comprise a second battery supplemental to the first battery, an external power input configured to couple to an external power source, a power output for powering the electronic device. The rechargeable battery pack can also comprise a first circuit comprising a first power path between the external power input and the power output, a second power path between the second battery and the power output, and a power switch set. When the external power source is decoupled from the external power input, the first power path is disabled by the power switch set, and the second power path is enabled by the power switch set. When the external power source is coupled to the external power input, the first power path is enabled by the power switch set, and the second power path is disabled by the power switch set. Other examples and embodiments are described herein.

Abstract: In one embodiment, an electronic accessory for coupling electronic devices to an external power supply includes: (a) a holder having: (1) a cradle section configured to couple to at least two of the electronic devices, the cradle section comprising a power coupling; and (2) two or more side supports, each of the two or more side supports configured to removably couple to the cradle section; and (b) a power unit electrically coupled to the power coupling and configured to removably couple to the external power supply. At least a first one of the two or more side supports is configured to provide support to a first one of the electronic devices when the first one of the electronic devices is coupled to the cradle section. At least a second one of the two or more side supports is configured to provide support to a second one of the electronic devices when the second one of the electronic devices is coupled to the cradle section. Other embodiments are disclosed in this application.

Abstract: An audio mixer for a portable media device includes: (a) an audio receiving mechanism capable of receiving audio signals from a plurality of components of a user's media system, modifying the characteristics of the received audio signals, summing the modified audio signals into a master audio signal, and outputting the master audio signal to a portable media device to be saved to the portable media device as a recording; (b) a docking station to receive a portable media device; and (c) a portable media device operating system.

Abstract: The present invention provides a method and system for providing a user with feedback as to the status of the command they have initiated by depressing a button, series of buttons or sequence of buttons on a human interface device (“HID”) for a time period beyond a fraction of a second to activate a function. In one embodiment, feedback provided for a press and hold (“P+H”) operation informs the user that their button press action has been detected by a multi-function device (“MFD”) and a visual and/or audible indication is provided, informing him or her to continue pressing the button or buttons on the HID to activate one or more functions. A graphical display with a periodically updated progress bar displays how much longer the user should continue pressing the button or buttons to successfully transmit a command to the MFD with an animation showing which command will be activated.

Abstract: A holder, electrical supply, and optional radio frequency transmitter unit to hold, supply power to, and receive a data signal from an operating electronic device when the device (e.g., MP3 player) is held in the unit is disclosed. Electrical power enters the unit's power acquisition portion (e.g., cigarette lighter adapter) from an external source and flows to the electronic device via the holder. A data signal from the electronic device is processed by an radio frequency transmitter in the unit, and the resulting radio frequency signal is broadcast by an antenna (e.g., gooseneck) that preferably forms a repositionable mechanical connection between the holder and the power acquisition unit.
