    Abstract: A low temperature radiometer includes a main body, a main cavity, an exit cavity, a suspended thermometer, and an attached thermometer. The main cavity is disposed within the main body and is defined through an off-axis parabolic concentrating cone formed of the inner walls of the main body. The exit cavity is disposed within the main body and is defined through a cylindrical inner surface of the main body. The suspended thermometer is suspended within the exit cavity and is disposed to be in communication with radiation entering the main cavity and being diverted to the exit cavity. The attached thermometer is attached to the outer surface of the main body and is in thermal communication and contact with the main body.

    Abstract: A filtration material comprising a blend of at least two types of fibers: (a) polypropylene fibers and (b) either acrylic or modacrylic fibers. In a preferred embodiment, the blend contains about 50 weight percent polypropylene fibers and about 50 weight percent modacrylic fibers. In another preferred embodiment, the blend contains about 50 weight percent polypropylene fibers and about 50 weight percent acrylic fibers. The fibers can be blended ranging from 90:10 to 10:90 polypropylene to acrylic or modacrylic. At least one type of fibers includes an extractable agent on the outer surfaces thereof. Performance of the blend is superior to the prior art filtration materials, especially at the preferred compositions.

    Abstract: A frequency modulation (FM) radio receiver includes a processing unit that may generate a magnitude value corresponding to a signal strength of each of a plurality of digital samples of a received FM signal. The receiver also includes a noise estimation unit that may filter the magnitude values using a high pass filter and may generate a noise value representative of a noise portion of the received FM signal based upon the filtered magnitude values.

    Abstract: A method and apparatus for enhancing signal quality within a wireless receiver are disclosed. An image of a desired signal is down-converted to a baseband signal by a digital down converter. The energy of the baseband signal is subsequently determined. If the energy of the baseband signal is equal to or greater than a predetermined threshold, then the IF is swapped for any incoming signals. If the energy of the baseband signal is less than the predetermined threshold, then the IF is maintained for any incoming signals.
