    摘要： A hydration sensor is provided that includes a circulator having a plurality of ports, an amplitude-modulated coherent source connected to a first port of the circulator, a rectifier or other power sensor connected to a second port of the circulator followed by an RF baseband low-noise amplifier, a coupling structure connected to the third port of the circulator, and a demodulator connected to the output of the rectifier. The hydration sensor can include an RF low noise amplifier between the circulator and rectifier, and/or a second amplitude modulator between the circulator and the coupling structure. The coupling structure can be either a guided-wave near-field structure or an interfacial capacitive or inductive element. In the former case, the hydration is determined by measuring the reflectivity of the guided-wave radiation, and in the latter case it is determined by measuring the change of reflectivity (through change of impedance) of the interfacial element.

    摘要： A system is disclosed for wirelessly detecting movement of a target. The system comprises a reference oscillator, a transmitter, a receiver, a demodulator, and a processor, wherein: the reference oscillator generates references frequencies for the transmitter, the receiver, and the demodulator; the transmitter generates a continuous-wave signal at a frequency based on the transmitter reference frequency and wirelessly transmits it to the target; the receiver wirelessly receives a reflected signal from the target having a phase angle corresponding to movement of the target and converts the reflected signal into an intermediate frequency signal based on the receiver reference frequency; the demodulator demodulates the intermediate frequency signal into an in-phase component and a quadrature component; and the processor converts the in-phase component and the quadrature component into a movement signal corresponding to movement of the target.

    摘要： Machine semantic perception is discussed. One example system can comprise an environmental knowledgebase (KB) associating features with properties, and an interface component receiving sensor data associated with observed properties. The KB and sensor observations can be encoded in bit-matrix and bit-vector representations, respectively, for efficient storage and computation. A perception component can perform semantic perception on observed properties based on the KB. The perception component can determine explanatory features associated with the observed properties through abductive reasoning, and determine discriminatory properties associated with the explanatory features through deductive reasoning. These can be executed in an iterative and interleaved Perception Cycle for efficient computation of minimum actionable explanations of observations. The bit-matrix and bit-vector representations are presented for efficient computation of minimum actionable explanation using perception cycle, the iterative and interleaved application of hybrid abductive and deductive reasoning to seek contextually relevant discriminatory observations to systematically narrow explanatory features.

    摘要： The subject innovation is directed to hierarchical structures characterized by ultrahigh surface area and methods of fabricating the same, as well as attachment of functional species to these structures to alter interactions of these hierarchical structures with their environments, such as by making them permanently or reversibly hydrophilic. One such example hierarchical structure can include a solid substrate, an intermediate layer, at least one plurality of nanoscale attachments that are strongly bonded to the intermediate layer, and an oxygen containing species coating the at least one plurality of nanoscale attachments.
