Abstract: A voltage-controlled oscillator includes a bias circuit and a delay circuit. The bias circuit may generate a bias voltage signal pair having levels that are based on the voltage level of an input voltage signal and that are constrained by the values of a maximum current signal and a minimum current signal that are generated in the bias circuit. The delay circuit generates an output signal having a frequency that varies in response to the bias voltage signal pair. Because an operating frequency range of a voltage-controlled oscillator VCO is limited by a bias circuit, the VCO can operate with reduced gain and can limit the maximum operating frequency to a predetermined level. The VCO may also include a PTAT current generator in the bias circuit which can allow the VCO to compensate for variations of the VCO output frequency based on temperature.

Abstract: A glass-coated amorphous metallic microwire is encoded with multi-bit digital information. Encoding is achieved magnetically, optically or through a combination of magnetic and optical encoding processes. Magnetic encoding is carried out by modifying the constituent magnetic domain structure through selective relief of interfacial stress between the glass coating and the amorphous metallic alloy core.

It is readily achieved by fluorescent element deposition, patterned removal of fluorescent element coating, Bragg grating, and thermally activated pattern deposition. The magnetic and optical multi-bit encoding approaches for glass-coated amorphous metallic microwire can be used individually or collectively in either a redundant or a complementary manner.

Abstract: An encoder uses an input file of data and a key to produce an output symbol. An output symbol with key I is generated by determining a weight, W(I), for the output symbol to be generated, selecting W(I) of the input symbols associated with the output symbol according to a function of I, and generating the output symbol's value B(I) from a predetermined value function F(I) of the selected W(I) input symbols. An encoder can be called repeatedly to generate multiple output symbols. The output symbols are generally independent of each other, and an unbounded number (subject to the resolution of I) can be generated, if needed. A decoder receives some or all of the output symbols generated. The number of output symbols needed to decode an input file is equal to, or slightly greater than, the number of input symbols comprising the file, assuming that input symbols and output symbols represent the same number of bits of data.
