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: 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.

Abstract: In some embodiments, an electrical accessory can be configured to transmit one or more first data signals to a receiving device.

Abstract: A cable organizer includes an upper surface, a lower surface, multiple channels, and at least one side surface. Other embodiments are disclosed herein.

Abstract: Some embodiments concern a method of transmitting electrical signals. The method can include: using a global positioning satellite receiver to determine a first location of a first electrical device; using a first transmitter to transmit the first location to a first server; using a receiver to receive information identifying at least one first unused frequency at the first location from the first server; selecting a first transmission frequency from the at least one first unused frequency; and communicating the first transmission frequency to a user. Other embodiments are disclosed in this application.

Abstract: A system for interfacing with an audio player comprises a housing (110, 410) containing a first connector (111, 411), a transmission device (120, 420) including a second connector (121, 421) capable of removable engagement with the first connector, a power interface (130, 430) electrically coupled to the housing, and an audio interface (140, 440) electrically coupled to the housing and capable of being coupled to the audio player. The transmission device is connectable both to the housing and to the audio player directly, and is capable of transmitting an audio signal generated by the audio player to a playback device such as a radio.
