  • Patent number: 9992729
    Abstract: A computer-implemented method for modifying operation of a portable processing device configured to scan for wireless signals under a first scan rate. As wireless signals are received in the portable processing device, characteristics of the wireless signals are analyzed, and if the characteristics match one or more characteristics, the operation of the portable processing device is modified. Under one exemplary embodiment, the first scan rate is modified to a second scan rate, where the second scan rate being different from the first. Under another exemplary embodiment, monitoring capabilities in the portable processing device are activated or modified to collect research data on media data. The characteristics may include identification information or messages/commands that are transmitted wirelessly.

  • Patent number: 9812109
    Abstract: System, apparatus and method for determining semantic information from audio, where incoming audio is sampled and processed to extract audio features, including temporal, spectral, harmonic and rhythmic features. The extracted audio features are compared to stored audio templates that include ranges and/or values for certain features and are tagged for specific ranges and/or values. Extracted audio features that are most similar to one or more templates from the comparison are identified according to the tagged information. The tags are used to determine the semantic audio data that includes genre, instrumentation, style, acoustical dynamics, and emotive descriptor for the audio signal.

  • Patent number: 9711152
    Abstract: Apparatus, system and method for encoding and/or decoding persistent universal media identification (ID) codes embedded in audio. For encoding, a persistent identifier code is generated or received from a registry database, where the code includes data for uniquely identifying a media object. Audio code components including frequency characteristics are generated to represent symbols of the persistent identifier code and the audio code components are psychoacoustically embedded into an audio portion of the media object to include the persistent identifier code within one or more of a plurality of encoding layers. Such embedded audio may be subsequently decoded by transforming the audio data into a frequency domain and processing the transformed audio data to detect the persistent identifier code.

  • Patent number: 9696336
    Abstract: Systems and methods are disclosed for identifying users of portable user devices according to one or more accelerometer profiles created for a respective user. During a media session, the portable computing device collects media exposure data, while at the same time, collects data from the accelerometer and compares it to the user profile. The comparison authenticates the user and determines the physical activity the user is engaged in. Additional data may be collected from the portable computing device to determine one or more operational conditions of the device itself, including the detection of multiple devices being physically carried by one user. Gross motion strings may also be generated by devices and compared to see if strings match, thus suggesting multiple devices are being carried by one user.
