摘要:
Some embodiments disclose an electrical accessory configured to transmit one or more first data signals from a first electrical device to a receiving device. The electrical accessory is also configured to transmit second data signals to the first electrical device. The first electrical device can include a first electrical connector and a second electrical connector. The electrical accessory can include: (a) a power acquisition unit configured to receive electrical power from an external power source; (b) a first electrical interface electrically coupled to the power acquisition unit and configured to mechanically and electrically couple to the first connector to provide the electrical power to the first electrical device; (c) a second electrical interface configured to mechanically and electrically couple to the second connector, the second electrical interface is configured to transmit the second data signals to the first electrical device and to receive the first data signals from the first electrical device; (d) a transmittal mechanism electrically coupled to the second electrical interface and configured to provide the first data signals to the receiving device; and (e) a first microphone electrically coupled to the second electrical interface and configured to receive sounds and convert the sounds into the second data signals. Other embodiments are disclosed in this application.

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.
摘要:
In some embodiments, an audio receiving device can be configured to couple to and produce an output signal for a portable media device. The audio receiving system can include: (a) a first microphone; (b) a second microphone; (c) a housing; and (d) an audio interface configured to electrically couple to the portable media device and provide the output signal to the portable media device. The first microphone can be coupled to the housing such that the first microphone can be rotated relative to the housing. Similarly, the second microphone can be coupled to the housing such that the second microphone can be rotated relative to the housing. Other embodiments are disclosed in this application.
