Abstract: An audio entertainment system having a primary circuit board with a processor in communication with an antenna input, an audio output and a connector. The processor is configured to detect the presence of the digital audio circuit board and to output an audio signal to the audio output based on the wireless signal. The wireless signal may be an AM, FM or digital satellite signal.

Abstract: Saturation of an RF front end in a radio receiver is prevented when receiving a desired radio broadcast signal via an antenna in the presence of a strong, undesired radio broadcast signal within a passband of the RF front end. An antenna signal from the antenna is coupled to the RF front end, thereby generating an amplified signal. The radio receiver demodulates the desired radio broadcast signal in response to the amplified signal, thereby generating a demodulated signal. A signal-to-noise quality parameter of the demodulated signal is determined. The antenna signal is attenuated prior to coupling it to the RF front end by an attenuation determined in response to the signal-to-noise quality parameter.

Abstract: A method to absorb magnetic fields begins by placing an electronic unit into a fixture. The electronic unit contains at least one electrical component, such as a microchip, that requires a reduction of a magnetic field. The microchip can be surrounded by a containment apparatus, such as a mold, into which encapsulant is poured. Exclusion devices, such as masks, protect components that should not be coated. Once the electronic unit is prepared, it is exposed to magnetic field interference. At this point, encapsulant is poured into all molds on the electronic unit. Ferrite particles comprise a portion of the encapsulant and initially are randomly distributed throughout. When the ferrite particles are exposed to a magnetic field, they migrate along the generated field lines and absorb the magnetic field. After the new distribution of ferrite particles occurs, the encapsulant can be cured.

Abstract: A method of precisely mounting a closure on a vehicle body so that the appearance features of the closure and the body are precisely mated when the closure is closed comprises the steps of attaching a first hinge link to the closure, making a net hole in the second hinge link at a precise location relative a certain appearance feature of the closure, and then installing a fastener between the net hole of the second hinge link and a mating net hole previously provided in the body at a precise location relative a certain appearance feature of the body. More particularly, a door hinge link is mounted on a transverse door surface at a location which establishes the hinge axis at a precise dimension transversely of the door outer surface and establishes the hinge at a precise location vertically from the top and bottom edges of the door.
