摘要： A method and apparatus for evaluation and inspection of a composite-repaired structure generates a frequency-varying electrical signal to test and evaluate the composite-repaired area. The electrical signal is converted into a mechanical signal and transmitted through the composite-repaired area of the structure. The transmitted mechanical signal is received and converted into an electrical signal for processing. The processed signal is compared with a baseline reference signal to determine whether the composite-repaired area is damaged or undamaged. The baseline reference signal is obtained at the time of the composite repair of the structure.

摘要： A computer, responsive to user input, controls the presentation of an audio-visual work to a user. Through the selection of several interactive learning options, support and reinforcement of the learning process is provided. In particular, the computer interacts with the user to challenge the user's understanding of the audio-visual work. In connection with the presentation of foreign language works, the user interacts with the computer in role playing, transcription, translation, fill-in-the-blanks and speech repetition activities designed to teach the user to speak the foreign language. Furthermore, as the audio-visual work is presented, a computer generated transcription or translation is displayed for user contemplation, and the user may interact with the computer by requesting the display of grammatical, cultural and geographic notes the further assist in the learning process.

摘要： An RF antenna (201) and an associated receiver (207) are proximately located in an integrated antenna/receiver unit (200) thereby eliminating the need for baluns and inter-component cabling characteristic of prior designs. Integration of the receiver (207) with the antenna (201) provides for improved sensitivity as the need for utilizing signal dissipating and noise introducing cables and baluns to transmit the signal received by the antenna to the receiver is eliminated. Direct coupling of the antenna and receiver on a single gallium arsenide integrated circuit (243) maintains balanced impedance from the antenna to the receiver.

摘要： A method and apparatus is provided for deriving the direction of a received signal from a signal source using first and second orthogonally-mounted loop (12, 14) antennas and an omnidirectional antenna (16). In operation, output signals from each of the antennas are generated and repeatedly supplied to signal processing circuitry in a cyclical fashion as the receiver is rotated to locate the transmitter. The amplitudes of the output signals from the first and second loop antennas are then compared (94) to determine whether the signal source is located in a null of the first loop antenna. If so, a null indication signal is generated. The phases of the output signals from the second loop antenna and the omnidirectional antenna are compared to determine whether the received signal is being received in a predetermined region of the second loop antenna. If so, an ambiguity indication signal is generated. The null indication signal and the ambiguity indication signal are then logically combined to generate a visual output (122) representing the direction of the signal source.
