Embodiments relate to a system and a method for a redundant real-time wireless receiver network. A Remote Digital Antenna Digital Receiver ('RDADR') is coupled to multiple Remote Digital Antenna ('RDAs'). The RDADR and the multiple RDAs are coupled via a digital bus. The multiple RDAs attempt to receive one or more digital signals from a transmitter. If the one or more digital signals are received without an error by one of the multiple RDAs, the RDA that received the one or more error-free digital signals sends the digital signals to the RDADR using the digital bus. The redundant real-time wireless receiver network provides a reliable and fault tolerant system to deliver digital audio signals in real-time.

Disclosed is a system and method for the real-time wireless transmission of digital audio signals. A transmitter including a processor may be used to: generate a first digital data stream and a second digital data stream from a digital audio signal and transmit the first digital data stream at a first radio frequency and the second digital data stream at a second radio frequency. A receiver including a processor may be utilized to: receive the first and second digital data streams at the first and second radio frequencies, respectively, and generate the digital audio signal from the first and second digital data streams.

A technique for reducing inherent noise in a real time digital audio wireless system. The technique allows for low power stereo analog to digital and digital to analog converters to be used in a battery operated real time digital audio wireless applications. The audio signal is sent to the left and right channels of an analog to digital converter with a preceding audio amp of different gain at the input to each channel. The signals are simultaneously digitized then combined to generate a new digital value resulting in noise reduction at lower amplitudes. This new data word is then transmitted via radio waves to a digital audio receiver. Once the data is received it is output simultaneously to a stereo digital to analog converter. The digital to analog conversion of both left and right channels is then summed using a resistor network and an audio amplifier. The audio amplifier output is then reduced to create further reduction of noise at all amplitudes.

A temporary vehicle cover includes a transparent cover and means for securing the transparent cover to the motor vehicle. The transparent is shaped to fit over a motor vehicle. The transparent cover includes a transparent cover top surface, a transparent cover bottom surface, a transparent cover first side, a transparent cover second side, a transparent cover rear end and a transparent cover securing end. Lengthwise perforations formed down substantially a middle of the transparent cover and separate the transparent cover first side from the transparent cover second side. The transparent cover first side is separated from the transparent cover second side to remove the temporary vehicle cover from a motor vehicle. A drawstring sewn into a hem of a perimeter of the temporary vehicle cover or an elastic loop may be used for the means for securing the transparent cover to the motor vehicle.

A portable wind tunnel features a tubular test section which has a constant cross-sectional area. The smaller end of a diffuser, which resembles a funnel, is attached to one end of the test section. The other end of the diffuser has a larger cross-sectional area. A flow generator, such as a fan, creates an airflow through the test section. The flow generator has an air inlet and an air outlet. A flow straightener is situated upstream from the air inlet of the flow generator normal to the direction of the airflow. The smaller end of a constrictor, which also resembles a funnel, is attached to the other end of the test section. The other end of the constrictor has a larger cross-sectional area.
