Abstract: A system (100) for communicating multimedia messages includes a multimedia message server (102) that is operable to transmit (1404, 1406, 1408) visual media, a vibration melody (1200), and an audio segment (1300) that is preferably filtered (1402) to exclude frequencies of the vibration melody (1200) through a network (104) to a client device (106), and is operable to, preferably at a later time, to transmit instructions (1410) to the client device (106) to output the vibration melody (1200), audio segment (1300) and visual media. At the client device, (106) the audio segment (1300) and the vibration melody (1200) and visual media are preferably stored (1504, 1508, 1512) in a memory (608) and in response to the instruction signal are read (1616, 1518, 1520) from the memory (608), decoded (1522, 1524, 1526) and output (1528, 1530, 1532) to a user. The vibration melody (1200) and the audio segment (1300) are preferably applied at least partially concurrently applied to an electromechanical transducer (212).

Abstract: An anechoic chamber (100) is provided with a system for introducing wireless communication signals into the anechoic chamber (100) for establishing wireless signaling with equipment under test (122), without interfering with signals from the equipment under test (122) that are to be measured in the anechoic chamber (100). The system comprises a low reflection cross-section cable (236) that extends through the chamber (100) to a weakly radiating small antenna (242, 502) that is positioned proximate the equipment under test (122).

Abstract: A highly versatile interface that is capable of digital and audio signal coupling is provided. The interface comprises contacts (122, 124, 216, 218) that are used to couple both audio and digital signals, and separate contacts (126, 220) that are used initiate and negotiate signaling mode transitions. Transitions can be effected without creating glitches, e.g., audible noise, in audio signals that are being coupled through the interface.
