摘要： A method of recording a plurality of audio signals associated with an entertainment sound system (42) of an automotive vehicle (12) includes an audio input (20). A plurality of audio signals (18) is transmitted from the audio input (20) to a controller (24) within the automotive vehicle (12). A preferred plurality of audio signals (36) is acoustically played on the entertainment sound system (42). A recorder (28) is actuated to record the preferred plurality of audio signals (34) onto an electronic medium (30) within the vehicle (42). Consequently, the preferred plurality of audio signals (34) is recorded onto the electronic medium (30). An acoustical transmission of the preferred plurality of audio signals (34) received from said audio input (20) is halted at a halting point. Finally, the acoustical transmission is resumed from the electronic medium (30), from the halting point simultaneously as the plurality of audio signals (18) continues being recorded.

摘要： A reliable, high data rate, downhole acoustic telemetry system is disclosed. In one embodiment, the acoustic telemetry system includes a tubing string with an acoustic transmitter and an acoustic receiver mounted on it. The acoustic transmitter transmits telemetry information by modulating an acoustic carrier frequency that propagates along the walls of the tubing string. The transmitter is preferably mounted at a selected position relative to the end of the tubing string. The selected position is preferably less than &lgr;/4 from the end or approximately n&lgr;/2 from the end, where &lgr; is the wavelength of the carrier frequency in the tubing string, and n is a positive integer. In a more preferred embodiment, n may be the lesser of 4 times the number of cycles in the modulating toneburst and 40. The receiver is preferably mounted at approximately (2n−1)&lgr;/4 relative to the end of the tubing string, where n is a positive integer. Such positioning prevents reflections of the acoustic signal from significantly degrading the received signal. The acoustic signaling advantageously employs pulse shaping to further improve system performance. To enhance data transmission rates, the acoustic receiver advantageously includes an equalizer that compensates for signal dispersion and intersymbol interference while simultaneously minimizing other forms of signal corruption such as additive noise and channel nonlinearities. The equalizer is preferably an adaptive, nonlinear equalizer that may also be fractionally spaced. Such equalizers eliminate any requirements for spacing intervals which allow signal reflections to die out. The resulting system is capable of higher data rates. When error correction codes are employed, no reliability losses are incurred.

摘要： A survey system (52, 154) is configured to identify radio stations (92) to which tuners (26) are tuned. The tuners (26) have predetermined signals (30) emitted therefrom. In one embodiment, the survey system (52) employs a method (86) which includes selecting one of the predetermined signals (30), receiving at a receiver (54) a second signal (116), and determining that one of the tuners (26) is tuned to one of the radio stations (92) when a harmonic (44, 46) of the fundamental frequency (42) of the predetermined signal (30) is detected within the second signal (116). In an alternative embodiment, the survey system (154) employs a method (182) that includes generating and broadcasting a survey signal (162) that is a one of the predetermined signals (30) modified to incorporate a signal identifier (212, 216). The method (182) further includes detecting a harmonic (44, 46) of the fundamental frequency (42) of the predetermined signal (30) within a received second signal (164) and determining that one of the tuners (26) is tuned to one of the radio stations (92) when the detected harmonic (44, 46) includes the signal identifier (212, 216).

摘要： A method and system for identifying data locations or uniform resource locators associated with physical observations in the real world. The method and system includes selecting certain physical parameters based upon an observation of real world objects and events and associating such physical parameters with data locations on the Internet or other computer network. When the real world object is observed or a real world event occurs, physical parameters relating to the object or event are sensed and recorded. These stored physical parameters are then communicated to a database, which returns a data location corresponding to the observed physical parameters. Thus, the present invention allows a user to “click” on objects or events in the real world in order to find data locations related to the objects or events in the on-line world.

摘要： A method and apparatus for data communication in an oil well environment, wherein the method comprises detecting an acoustic signal transmitted along an acoustic channel, the acoustic signal being distorted from transmission through the acoustic channel, generating a transmitted data signal in response to the acoustic signal, inputting the transmitted data signal to an adaptive equalizer and adaptively equalizing the transmitted data signal to produce an equalized data signal related to the transmitted data signal by a mathematical function. The detecting step may include positioning an acoustic receiver in a communication unit along the acoustic channel. The communication unit may be positioned downhole and the adaptive equalizer may be positioned remotely relative to the communication unit or may be placed in the communication unit. The adaptive equalizer may be a frequency domain filter, a neural net adaptive equalizer or a nonlinear recurrent neural net equalizer. The acoustic signal may comprise a plurality of discrete transmissions which may be a training sequence for training the adaptive equalizer and may comprise a first discrete transmission transmitted repeatedly. The method of data communication in an oil well environment may comprise the steps of transmitting an acoustic signal from a first location along an acoustic channel, detecting the acoustic signal at a second location along the acoustic channel, generating a transmitted data signal in response to the acoustic signal, inputting the transmitted data signal to an adaptive equalizer and adaptively equalizing the transmitted data signal to produce an equalized data signal related to the transmitted data signal by a mathematical function. The transmitting step may further comprise positioning an acoustic transmitter in a first communication unit along the acoustic channel downhole or elsewhere. The method may further comprise acquiring data, generating an original data signal in response to the acquired data and inputting the original data signal to the acoustic transmitter. The acoustic signal may comprise a series of acoustic training signals for training the adaptive equalizer. The acoustic training signals may be transmitted at a predetermined time. A stored training signal may include a series of stored training data signals corresponding to the series of acoustic training signals. At least a portion of the stored training signals may be cross-correlated to the transmitted data signal. The acoustic signal may comprise a notification signal for notifying the adaptive equalizer of a training session.
