| 20090047919 | RADIO WITH AUTOMATIC TUNING TO MODULATED AUDIO DEVICE - A system and method for automatically tuning an entertainment system to interface with a modulated audio device includes a processor in communication with a tuner, an audio output device and a memory unit containing processor executable instructions. The processor executable instructions of the memory unit configure the processor to tune the tuner to a predetermined frequency, determine if a signal is present at the predetermined frequency and output an audio signal based on the predetermined frequency to the audio output device if a signal is present at the predetermined frequency. | 02-19-2009 |
| 20090103751 | SOUND VOLUME LEVELER FOR SPEED SENSITIVE VOLUME - A system and method for adjusting an output sound signal for an audio device includes a speed sensitive volume transfer unit, a dynamic processing unit and a sound volume update unit. The speed sensitive volume transfer unit is configured to output a volume gain signal based on a speed sensitive volume setting input, a volume gain input and an adjustment signal. The dynamic processing unit is in communication with the speed sensitive volume transfer unit and is configured to output a modified volume signal based upon the adjustment signal and the volume gain signal. The sound volume update unit is in communication with the dynamic processing unit and a raw sound signal. The sound volume update unit outputs a corrected sound signal based on the modified volume gain signal and the raw sound signal. | 04-23-2009 |
| 20090163162 | DIRECT CONVERSION RECEIVING ARCHITECTURE WITH AN INTEGRATED TUNER SELF ALIGNMENT FUNCTION - A direct conversion receiver with an integrated self alignment tuner. The system includes a tank circuit, an analog to digital converter, a digital down converter, a digital up converter, a local oscillator, and a digital to analog converter. The tank circuit receives a radio frequency signal from an antenna input. The analog to digital converter is connected to the tank circuit to digitize the tank output signal and generate a corresponding digital signal. The digital down converter is in communication with the analog to digital converter and generates an intermediate frequency signal based on the digital signal and the output of the local oscillator. The digital up converter is in communication with the digital to analog converter to generate a radio frequency test signal, where the digital to analog converter provides the radio frequency test signal to the antenna input. | 06-25-2009 |
| 20090178084 | SYSTEM AND METHOD FOR AFFINITY MARKETING TO MOBILE DEVICES - A method and system for providing selected content displays to users of mobile electronic devices and more specifically to a method and system for broadcasters to provide a marketing portal presented in the form of displayed customized broadcaster content. | 07-09-2009 |
| 20090278594 | FRAME-BASED LEVEL FEEDBACK CALIBRATION SYSTEM FOR SAMPLE-BASED PREDICTIVE CLIPPING - A feedback calibration system and a method for controlling an electronic signal are disclosed. The feedback calibration system includes an input controller adapted to modify an input signal in response to a control signal and generate a modified input signal, a signal processing block including a signal analyzer, wherein the signal processing block is adapted to process the modified input signal to generate an output signal and the signal analyzer is adapted to detect an undesirable condition of the output signal and transmit a detection signal corresponding to the undesirable condition, a transfer function estimator adapted to model and transmit a transfer function estimate of the signal processing block in real-time in response to the detection signal, and a programmable device adapted to transmit the control signal to the input controller for modifying the input signal, wherein the control signal is based upon the transfer function estimate. | 11-12-2009 |
| 20090320067 | SYSTEM FOR DOWNLOADING AUDIO CONTENT - A method for recording a clean broadcast free of background, such as fade-ins and fade-outs on a receiver includes providing program data associated with an upcoming broadcast, the broadcast being selected by a broadcaster, on the receiver to describe the upcoming broadcast to a user. The receiver records the upcoming broadcast to an internal memory of the receiver in response to either the broadcast being automatically selected based on the user's preferences or the user manually selecting the upcoming broadcast. Start and stop commands, independent of any manual input, are received by the receiver to begin and end the recording of the clean broadcast. | 12-24-2009 |
| 20100130152 | AUTOMATIC BANDWIDTH CONTROL WITH HIGH-DEVIATION DETECTION - A signal processing system and methods for controlling a bandwidth of the signal processing system are disclosed. One method includes the steps of detecting a presence of an adjacent signal on at one adjacent channel relative to a desired channel, detecting a modulation characteristic of the desired channel, measuring a signal strength on the at least one adjacent channel, measuring a signal strength on the desired channel, and adjusting a bandwidth filter applied to the desired channel in response to the measurements and detection steps. | 05-27-2010 |
| 20100151811 | Direct Conversion Pre-ADC Frequency Mixer - A system for single path processing identical, substantially identical, close or interfering frequencies with a single analog-to-digital converter. The system receives a plurality of input signals at various frequencies and front end circuits filter out first and second frequencies. A mixer and a front end oscillator are in communication with one of the front end circuits for mixing a front end frequency with one of the first and second frequencies prior to the analog-to-digital converter. A summer combines the output of the mixer with the output of one of the front end circuits. An analog-to-digital converter is connected to the summer for converting the analog input signal to a digital output signal. The first and second frequencies may be separately processed after they have been combined, even if they were identical frequencies. | 06-17-2010 |
| 20110103435 | HD RADIO DIVERSITY RECEIVER WITH SHARED PROCESSING PATHS - A receiver including a plurality of antennas for receiving at least one radio signal, an analog processing path in signal communication with at least one of the antennas, a digital processing path in signal communication with at least one of the antennas, and a processor for controlling a processing of the at least one radio signal, wherein the at least one radio signal is processed by at least one of the analog processing path and the digital processing path. | 05-05-2011 |
