Abstract: A multi-channel digital video receiver (e.g. DBS) includes a tuning unit with two tuner modules and a decoder unit with two decoder modules. These tuner and decoder units enable the receiver to simultaneously produce decoded video and audio signals for two separately-tuned channels. The signals for the channel currently selected by the user are tuned and decoded by one set of tuner and decoder modules. The decoded signals for the selected channel are sent to an output stage (e.g. encoder), where the signals and their output are encoded for use on an attached presentation device (e.g. television, audio processor, computer, etc.) Simultaneously, a microcontroller predicts the next channel the user will select and causes the other tuner and decoder modules to begin tuning to and decoding the signals for that predicted next channel. A third set of tuner and decoder modules can be added to enable the receiver to begin tuning to and decoding the signals for another likely next channel.

Abstract: A rain cap system which keeps rain, snow, wind, dirt, dust, and other elements from penetrating the assembly junctions of Fast Structures.TM.. Four gaskets are placed (one each) on the four structural bolts at each junction of the Fast Structure.TM. and a rain cap is snapped into place completely covering each junction. The rain cap squeezes the Fast Structure.TM. junction to seal out the weather and to hold itself in place, and thus does not require nuts, screws, bolts, glue nor any other fastening devices.

Abstract: A meter (10) for measuring extremely-low-frequency radiation includes a coil circuit (22) whose output is filtered by a sharp-cut-off high-pass filter (24) to pass standard house-current frequencies but suppress the frequency components that would predominate as a result of movement of the meter with respect to the earth's magnetic field. An integrator (26) compensates for the frequency response of the coil circuit (22), an RMS circuit (35) converts the signal to its root-mean-square value, and a display circuit (28) provides a display determined by the resultant signal.
