Abstract: A logic device for use with data signals having a continuously or semi-continuously varying waveform of substantially fixed frequency. The device provides a logical output from at least one of the data inputs and comprising a first pair of inputs each to receive a data signal having one of a predetermined set of values representing analog, discrete, or digital states. A combiner stage is used to combine the inputs and produce a signal therefrom. A filter stage is utilized to receive the signal and produce a conditioned signal representative of one of a pair of binary states. The conditioned signal is combined with a second control input. The resultant signal is passed to an output.

Abstract: A shaped chip-type snack comprising excluded portions that form holes, notches, and sides. Chips can include combinations of hole, notches, and sides. Holes are preferably the size of an average human adult finger, an average child finger, or larger than a finger. The holes, notches, and sides can be any desired shape, including geometric and non-geometric shapes. Any type of chip can be used. Chips are preferably made from any edible material.

Abstract: A tunable electromagnetic field frequency filter which includes a bus waveguide that carries a signal having a plurality of frequencies, including at least one desired frequency, and a receiver waveguide. A resonator-system is coupled to the bus and receiver waveguides via couplers, such as directional couplers, and transfers the desired at least one frequency from the bus waveguide to the receiver waveguide while allowing transmission of the remaining frequencies in the bus waveguide. The signal in the bus waveguide is coupled from the bus waveguide to the resonator-system by a first coupler. The first coupler splits the input signal into preferably equal parts and directs each part into the resonator-system. The resonator-system supports at least two system modes, and includes at least three reflectors (G1, G2, G3) with at least two different reflectivity spectra. Two resonators (R1, R2) are defined by the three reflectors.
