A radio frequency ('RF') repeater system can receive, from a connected home device, an original RF signal that is unable to propagate through an object. The RF repeater system can demodulate the original RF signal to extract a data stream that includes data captured by the connected home device, can change an original data rate of the data stream to a new data rate that matches an ultrasonic frequency capable of propagating through the object thereby creating an ultrasonic data stream, can transmit, by a first surface transducer, the ultrasonic data stream through the object to a second surface transducer, can receive, by the second surface transducer, the ultrasonic data stream, can change the data stream from the new data rate back to the original data rate, can modulate the data stream to create a new RF signal, and can transmit the new RF signal towards the destination.

A system, apparatus, method and computer program product to obtain comprehensive vehicle radio listener statistics based on parameters such as radio status (e.g., on/off status and CD/Tape/AM/FM setting), radio volume, station preset information, current frequency setting (i.e., station identification), and Global Positioning Satellite (GPS) system coordinates is disclosed. A vehicle-mounted field unit for collecting and transmitting such parameters to a base station is also disclosed. The system monitors and stores all events related to the occupants' interaction with the vehicle's radio, including automatic detection of the selected radio station through a speaker port. The stored data is then transmitted to a base station's central collection computer for immediate compilation and analysis. The system is capable of producing detailed reports containing error-free, unbiased, audience measurement statistics which can be made available to subscribers such as broadcasters, corporate advertisers, advertising agencies and the like.

System and method for obtaining comprehensive vehicle radio listener statistics

A method and apparatus for measuring a characteristic of a communication signal modulated with a composite video signal without the need for a synchronizing device. Samples are taken of an intermediate signal derived from the received communication signal that represents the power spectrum of the communication signal at different instants of time. From a priori knowledge of the spectral characteristics of the communication signal modulated with a composite video signal, predetermined features of the communication signal are identified based on the relative values of the samples collected over a period of time equal to an entire frame of the composite video signal. The sample with the maximum value of a plurality of sample values collected for one frame is coincident with the occurrence of a vertical synchronization pulse of the composite video signal, which occurs when no modulation is present, and therefore is representative of the power of the communication signal at the visual carrier frequency. Once the sample with the maximum value sample is identified, the beginning of a frame is known, and therefore the power level of any other portion of the composite video signal can be measured based on the power level of the communication signal at a particular point in time with respect to the point in time that the maximum value sample occurred.
