Abstract: A retractable ear bud case having a separate plug wire and ear bud wire is disclosed. Each wire is wound about a separate spool assembly. The spool assemblies provide for electrical connection between the wires, even as they rotate about one another in order to allow for independent payout of either wire. A lock assembly provides for smooth, controlled noiseless payout and immediate locking once a desired distance is reached. Each wire is automatically retracted upon release of the locking assembly. The case may provide housings for ear buds, a male plug, and a microphone, all of which may be components of the invention according to certain embodiments.

Abstract: An wireless communication device with an antenna (400) for sending and receiving signals in a plurality of frequency bands generates a plurality of resonances in the plurality of frequency bands and includes a first radiating element (402) that generates a first resonance in a first frequency band, a second radiating element (404), coupled to and extending at an angle from the first radiating element (402), that generates a second resonance in the first frequency band, and a third radiating element (406), coupled to and extended at an angle from the first radiating element (402). A capacitive coupling between the second radiating element (404) and the third radiating element (406) generates a loop with a third resonance in the first frequency band, and the third radiating element (406) generates a fourth resonance in a second frequency band independent of the loop at the second frequency band.

Abstract: An antenna for sending and receiving signals in a plurality of frequency bands generates a plurality of resonances in the plurality of frequency bands and includes a first set of radiating elements (302) that generates at least one resonance in a first frequency band, and a second set of radiating elements (304) that generates at least one resonance in a second frequency band. At least one resonance is generated in a capacitive loop that exists at certain frequencies between at least two radiating elements belonging to a combination of the first set and the second set of radiating elements.
