An automotive radio receiver includes an over-the-air radio tuner and a network interface. When a broadcast received at the radio receiver, it includes embedded information that can be used to identify the radio station providing the broadcast. The radio receiver uses the embedded information to identify a streaming station that corresponds to the broadcast station. The radio receiver transmits information associated with the streaming station to a web service, which returns an address at which the radio receiver can access the streaming station. The address of the streaming station is stored in a memory accessible to the radio receiver for later use. The next time the radio receiver is tuned to the same broadcast station, the radio receiver instead connects to the streaming station at the stored address.

Disclosed is a digital radio frequency (RF) signal receiving apparatus including an RF filter configured to convert multichannel wireless signals received through an antenna into signals available for digital sampling, an analog-to-digital converter configured to perform digital sampling on the multichannel wireless signals converted by the RF filter, a digital processor configured to perform filtering on each of the digital-sampled multichannel wireless signals into a plurality of bandwidth signals within a maximum bandwidth range simultaneously, and down-convert the filtered multichannel wireless signals to be signals in a baseband, a data formatter configured to format the down-converted signals based on an input/output data form of transmission interfaces, and a data transmitter configured to simultaneously transmit each of formatted signals to a corresponding processing platform.

Systems and methods are presented for increasing throughput between mobile transmitters/receivers (e.g., between an Unmanned Aerial Vehicle and a ground station) using orthogonally polarized transmission channels. The system may first calibrate the receiver and transmitter antenna pairs using pilot signals and then may update look up tables for feedforward correction. The system may decouple and predict the cross polarization interference due to relative dynamic movement between the transmitter and the receiver. The system may perform a closed-loop suboptimal estimation to generate refined corrections by minimizing a difference between a training vector and a pilot-signal feedback. Cross-polarization discrimination between the transmission and reception antennas may then be Cancelled to improve signal to noise and interference ratio and performance of the system.

A radio-frequency module includes a mounting board having first and second major surfaces opposite to each other and a duplexer including a transmit filter coupled to a node and a receive filter coupled to the node. The transmit filter is mounted on the first major surface, and the receive filter is mounted on the second major surface. When the mounting board is viewed in a plan view, a footprint of the transmit filter at least partially overlaps a footprint of the receive filter.

Various data transmission detection systems are described. A receiver input through which a wireless data transmission signal is received may be present. A plurality of mixers in communication with the receiver input may be present, which may be digitally implemented. A data transmission detector may be present that receives a mixed wireless data transmission signal from each mixer and creates a plurality of scores. A match detection module may be present that receives the scores and identifies a highest score. The signal mapped to the highest score to be selected for further processing.

A system for providing shower entertainment. The system includes a horizontally extendable shower rod including a first portion and a second portion, wherein the second portion is configured to retract into and extend from a channel disposed within the first portion, a plurality of lights disposed along an exterior surface of the shower rod, a plurality of speakers configured for playing sounds, a processor communicably coupled to the plurality of lights and the plurality of speakers, the processor configured for receiving audio data, via radio frequency, and playing said audio data on the plurality of speakers, and activating and deactivating the plurality of lights; and a rechargeable battery configured for providing power to the plurality of lights, the plurality of speakers and the processor.
