A wireless power transmission system includes first source conductor that generates a first electromagnetic near field in response to a power source. A first source element resonates in response to excitation from the first source conductor. A second resonant source element resonates in response to excitation from the first source conductor. A first resonant load element resonates in response to excitation from the first resonant source element. The first resonant load element generates a fluctuating field when resonating. A second resonant load element resonates at the second resonant frequency in response to excitation from the second resonant source element. The second resonant load element generates a fluctuating field when resonating. A first load element generates a first current applied to a first load in response to resonance in the first resonant load element and the second resonant load element.

A diffusion sampler includes an elongated tubular support structure, a top end cap, a bottom end cap, a first coupling device, at least a first membrane and a reservoir mechanism. The support structure has an outer wall that defines an interior space therein. The outer wall defines a plurality of openings. A membrane is disposed around the outer wall at least in the area of the upper portion of the support structure and is configured to allow at least one first selected type of molecule to pass therethrough. A reservoir mechanism is coupled to a bottom portion of the support structure and is configured to define a reservoir in the lower portion of the support structure that prevents a selected liquid from flowing out of the lower portion of the support structure.

A communication element includes a high electron mobility transistor including a gate layer. A graphene layer is disposed on the gate layer. A communication system includes a signal source, a plasmonic transmitter, a first plasmonic antenna, a second plasmonic antenna, a plasmonic receiver and a signal detector. The signal source generates a transmitted signal. The plasmonic transmitter generates a first surface plasmonic polariton wave signal corresponding to the transmitted signal. The first plasmonic antenna generates an electromagnetic signal corresponding to the surface plasmon polariton wave signal. The second plasmonic antenna generates a second surface plasmon polariton wave signal corresponding to the electromagnetic signal. The plasmonic receiver generates a received signal corresponding to the second surface plasmon polariton wave signal. The signal detector detects the received signal.

A generator for harvesting energy from water in motion includes a sheet of a hydrophobic material, having a first side and an opposite second side, that is triboelectrically more negative than water. A first electrode sheet is disposed on the second side of the sheet of a hydrophobic material. A second electrode sheet is disposed on the second side of the sheet of a hydrophobic material and is spaced apart from the first electrode sheet. Movement of the water across the first side induces an electrical potential imbalance between the first electrode sheet and the second electrode sheet.

In a countermeasures control interface for use in deploying countermeasures in response to user commands, which are deployed from a first countermeasure dispenser that deploys a first type of countermeasure and a second countermeasure dispenser that deploys a second type of countermeasure different from the first type. A user interface receives user commands regarding countermeasures deployment and includes a display that shows a user-selectable image formats. At least one of the user-selectable image formats includes a graphic representation of a loadout of the first countermeasure dispenser and the second countermeasure dispenser, as well as a graphical representation of currently-available countermeasures deployment options. The user interface also receives input regarding a user countermeasure deployment choice and generates a signal corresponding to the countermeasure deployment choice. An electronic circuit controls the display and generates the user-selectable image formats, receives the countermeasure deployment choice from the user interface and activates the countermeasure dispensers.

In a method of filtering an image from data received from a CMOS camera, image data is loaded by a computational device from the camera. Camera parameters corresponding to the CMOS camera are loaded. Fixed pattern noise associated with the camera is removed based on the camera parameters. A readout noise estimation based on characteristics of the camera and filtering estimated readout noise from the image data is generated. Sparse filtering: selecting sub-frames within the image that have similar features; applying a three-dimensional transform on the sub-frames transforming the sub-frame data into a non-two-dimensional domain and generating a first transformed data set; filtering noise data from the first transformed data set to generate a first thresholded image data set; and applying a reverse three-dimensional transform on the first thresholded image data set so as to generate an image.

In a method for recycling energy from stairs, a step platform is moveable between an upper and lower position. An energy storage device, coupled to the platform, stores energy when a downward force is applied thereto, causing the step platform to move to the lower position. The energy storage device (also releases stored energy as the step platform moves from to the upper position. A controllable locking mechanism (locks the step platform in the lower position when the downward force has caused the step platform to move into the lower position. A sensor determines when a downward force has been applied to the next higher step platform. A controller signals the controllable locking mechanism to unlock the step platform when the step platform is in the lower position, and when the downward force has been applied to the next higher step platform.

A modular commercial structure includes a first exterior module defining a first interior space therein in which office furnishings are disposed in the first interior space. The first exterior module has an interior elongated side that defines an opening for customers to access to the first interior space. A second exterior module defines a second interior space for conducting business activities therein, including an interior elongated side that opens to facilitate interaction between the customers and employees. A conveyance mechanism moves the first exterior module and the second exterior module between a first position and a second position to prevent access to the first interior space and to the second interior space while in the first position and to provide access to the first interior space and to the second interior space while in the second position.

In a method of warning of a hazardous electrical condition at a dock with wiring coupled to a voltage source via a dock breaker, an electric voltage between a ground and at least one of the dock frame or the water is detected. A plurality of voltage values of the electric voltage is stored. When at least two successive voltage values of the plurality voltage values exceeds a baseline safe voltage by a preset margin, then a shock warning signal is asserted, a dock breaker is opened and a shock warning indication is transmitted to a remote unit via a communication chipset. When at a voltage is sensed in the dock wiring system after the dock breaker has been opened, then a faulty dock breaker warning indication is transmitted to the remote unit via the communication chipset.
