Energy packet switches (EPS) employing supercapacitors as storage provide aggregation and delivery of energy to users based on shared-capacitance in a digital power grid. The EPS aggregates energy from one or multiple energy sources, stores and dispatches the energy in discrete amounts as energy packets to one or multiple users. The payload of the energy packet is adjusted by the voltages of the supercapacitors which are used as energy containers for both the EPS and the users. The EPS has a control plane where data transmitted is used to control the operation of the EPS, and a power plane to receive and transmit energy between ports. The power and data planes work in parallel and with a parallel data network. Control and management of the EPS are based on a request-grant transport protocol. The data network is used to receive energy requests and grants, and a granting scheme is used to select which loads are granted energy. By sending addresses of granted loads on the data network and energy on the energy grid, energy is delivered to addressed destinations.

Energy packet switches

Methods and apparatus for packetized energy distribution are provided. A data and power delivery network, called a digital grid, is provided to facilitate delivery of power upon request. Energy bits (quanta) serve as a means to deliver energy as well as coding. Voltage pulses of varying time scales are used for coding and current levels help to accurately meet customer's demand. Energy is sent as packets (a combination of energy bits), and specific energy packets are addressed to specific customers permitting accurate monitoring and distribution of electrical energy.

Packeted energy delivery system and methods

Methods, devices, systems and/or articles related to techniques for forming a graphene film on a substrate, and the resulting graphene layers and graphenated substrates are generally disclosed. Some example techniques may be embodied as methods or processes for forming graphene. Some other example techniques may be embodied as devices employed to manipulate, treat, or otherwise process substrates, graphite, graphene and/or graphenated substrates as described herein. Graphene layers and graphenated substrates produced by the various techniques and devices provided herein are also disclosed.

Graphene deposition and graphenated substrates

A non-periodic reflection beamsplitter or reflector for use in an interferometer. The interferometer employs non-periodic reflectors or a non-periodic beamsplitter in order to produce interference patterns to analyze. The non-periodic reflectors or beamsplitters may be concentrically arranged reflectors having equal area. The beamsplitter consists of two adjacent non-periodic structures having complementary reflection and transmission patterns.

Non-periodic wavefront dividing interferometer

Methods to infer the density of defects in high &#x3ba; dielectric films in a non-contact, non-invasive and non-destructive manner. THz radiation is employed to measure the change in electrical conductivity of the films before and after illumination with visible light, where the visible light photoionizes the defects thereby changing the electrical conductivity and changing the transmission (or reflection) of THz radiation from the films. The disclosed techniques can be employed to make measurements as soon as wafers are fabricated. The technology is applicable to wafers of any size.

A dipole array is provided for use as an Ultra Short Pulse (USP) transmitter or receiver in UWB communications systems, which reduces the output pulse dispersion. Instead of having all the dipole elements serially fed by a transmission line, the feeding in the array is made independently through a central point and the radiation is emitted and received broadsided with respect to the array plane. This configuration minimizes the relative time delay between radiating resonance frequencies.

Independently center fed dipole array

An active coating system capable of collecting, analyzing, managing and adapting to data and/or its environment in real time. An exemplary embodiment of our inventive active coating system is corrosion resistant and includes a flexible sensor layer, a switch layer and a visual display layer. Operationally, the flexible sensor layer senses particular environmental conditions and the visual display layer provides visual indication of the condition(s) sensed.

Smart coating system

A multilayer coplanar waveguide having a fine-patterned conductive top cover coated with a photosensitive material for optically controlling the phase shift within the waveguide. The multilayer coplanar waveguide comprises a conductive ground plane, a first dielectric layer formed on the conductive ground plane, a second dielectric layer formed on the first dielectric layer, a conductive signal carrier and a pair of conductive floating ground planes flanking the conductive signal carrier formed on the second dielectric layer, a third dielectric layer formed on the conductive signal carrier, the pair of conductive floating ground planes, and the second dielectric layer, fine-patterned conductive strips formed on the third dielectric layer, and a photosensitive material layer formed on the fine-patterned conductive strips and the third dielectric layer. The photosensitive material, when illuminated, generates free electrons which drift toward the conductive strips thereby increasing the resistance between the conductive strips and increasing the phase delay of signals propagating through the waveguide. Thus, the phase shift within the multilayer coplanar waveguide is optically controllable.
