    Abstract: A device includes, in part, an antenna adapted to receive an RF signal that includes modulated data, a splitter/coupler adapted to split the received RF signal, a receiver adapted to demodulate the data from a first portion of the RF signal, and a power recovery unit adapted to convert to a DC power a second portion of the RF signal. The splitter/coupler is optionally adjustable to split the RF signal in accordance with a value that may be representative of a number of factors, such as the target data rate, the DC power requirement of the device, and the like. The device optionally includes a switch and/or a power combiner adapted to deliver all the received RF power to the receiver depending on any number of operation conditions of the device or the device's distance from an RF transmitting device.

    Abstract: A nanoelectromechanical systems (NEMS) oscillator network and methods for its operation are disclosed. The NEMS oscillator network includes one or more network inputs configured to receive one or more input signals. The NEMS oscillator network also includes a plurality of NEMS oscillators coupled to the one or more network inputs. Each of the plurality of NEMS oscillators includes a NEMS resonator and produces a radio frequency (RF) output signal that oscillates at a particular frequency and a particular phase. The NEMS oscillator network further includes a plurality of connections that interconnect the plurality of NEMS oscillators. The NEMS oscillator network further includes one or more network outputs coupled to the plurality of NEMS oscillators and configured to output one or more output signals.

    Abstract: A method and system provide the ability to compile computer source code. The source code is pre-processed to generate pure source code that includes definitions required for interpretation. The pure source code is formalized in a compiler, into assembly language that is processor specific. The formalization includes determining a set of two or more optimization routines, randomly selecting a selected optimization routine from the set of two or more optimization routines, and applying the selected optimization routine to each segment of the pure source code in a serialized manner. An executable binary file is then output and executed based on the formalized pure source code.
