    摘要： Wireless devices, and particularly mobile devices such as cellphones, PDAs, computers, navigation devices, etc., as well as other devices which transmit or receive data or other signals at multiple frequency bands utilize at least one antenna to transmit and receive and a plurality of different bands (e.g., GSM cellular communication band; Bluetooth short range communication band; ultrawideband (UWB) communications, etc.). These wireless devices can simultaneously transmit or receive at a plurality of different bands, or simultaneously transmit and receive at different bands. The wireless devices have the ability to use a single physical structure (e.g., an antenna) for transmission and reception of many different bands. The antenna can be either actively tuned or passively tuned using one or more elements.

    摘要： A pickup cable for a stringed instrument can switch between the output of the direct vibrational sound of strings and the output of the sound from the stringed instrument body generated by the vibrations of the strings and can also simultaneously output both the sound components. The pickup cable for a stringed instrument includes an input terminal to be inserted in a jack of the stringed instrument; a microphone to collect and convert sound of an internal space of the stringed instrument into collected-sound electrical signals; and an output terminal to output the collected-sound electrical signals. The microphone is incorporated in the input terminal.
