摘要： A neuromodulator includes one or more coil sets. Each of the coil sets has three coils aligned to produce magnetic and electric fields in three different directions. A plurality of conductors couple the coils of the one or more coil sets to one or more input signals such that each of the coils is independently activated via an individually selectable current applied through the conductors. The individual activation creates a resultant field that is a combination of the magnetic and electric fields in three different directions for each of the coil sets.

The at least one water reservoir comprises an input and an output, wherein water in the at least one water reservoir is reduced below a threshold concentration during a desalination operation mode. The at least one negative-ion electrode comprises a first solution and is configured to accept, and have, a reversible redox reaction with at least one negative ion in the water, and the at least one positive-ion electrode comprises a second solution and is configured to accept, and have, a reversible redox reaction with at least one positive ion in the water.

摘要： The system and method described below allow for real-time control over positioning of a micro-object. A movement of at least one micro-object suspended in a medium can be induced by a generation of one or more forces by electrodes proximate to the micro-object. Prior to inducing the movement, a simulation is used to develop a model describing a parameter of an interaction between each of the electrodes and the micro-object. A function describing the forces generated by an electrode and an extent of the movement induced due to the forces is generated using the model. The function is used to design closed loop policy control scheme for moving the micro-object towards a desired position. The position of the micro-object is tracked and taken into account when generating control signals in the scheme.

摘要： A metamaterial-based phase shifting element utilizes a variable capacitor (varicap) to control the effective capacitance of a metamaterial structure in order to control the phase of a radio frequency output signal generated by the metamaterial structure. The metamaterial structure is configured to resonate at the same radio wave frequency as an incident input signal (radiation), whereby the metamaterial structure emits the output signal by way of controlled scattering the input signal. A variable capacitance applied on metamaterial structure by the varicap is adjustable by way of a control voltage, whereby the output phase is adjusted by way of adjusting the control voltage. The metamaterial structure is constructed using inexpensive metal film or PCB fabrication technology including an upper metal “island” structure, a lower metal backplane layer, and a dielectric layer sandwiched therebetween. The varicap is connected between the island structure and a base metal structure that surrounds the island structure.

摘要： A lightweight deployable antenna assembly for, e.g., microsatellites including multifilar (e.g., quadrifilar) antenna (MHA) structures rigidly maintained in an array pattern by a lightweight linkage and collectively controlled by a central antenna feed circuit and local antenna feed circuits to perform phased array antenna operations. The linkage is preferably an expandable (e.g., flexural-scissor-grid) linkage capable of collapsing into a retracted/stowage state in which the MHA elements are maintained in a closely-spaced (e.g., hexagonal lattice close-packed) configuration optimized for payload storage. To deploy the antenna for operation, the linkage unfolds (expands) such that the MHA elements are moved away from each other and into an evenly spaced (e.g., wide-spaced hexagonal) pattern optimized for phased array operations. The MHA structures utilize modified helical filar elements including metal plated/printed on polymer/plastic beams/ribbons, or thin-walled metal tubes. The helical filar elements are radially offset (e.g., by 90°) and wound around a central axis.

摘要： A wastewater treatment plant that employs an activated sludge process and a method of operating the same is described. Wastewater influent is provided to a bioreactor configured to perform activated sludge processing to develop mixed liquor suspended solids (MLSS). The MLSS is passed from the bioreactor to a hydrodynamic separator (HDS) system, where separation operations are performed on the MLSS. The separation operations generate a low concentration MLSS stream and a high concentration MLSS stream. The low concentration MLSS stream is passed from the hydrodynamic separator system via a first output to a clarifier, and the high concentration wastewater stream is passed via a second output back to the bioreactor. The clarifier performs clarification operations on the cleaned wastewater stream and then outputs an effluent flow.
