Abstract:
One embodiment of a toy (22) having a plurality of balls (12) inside a container (26). Demonstrating ball interactions without the balls (12) making physical contact with one another can be accomplished with a flat, surface (20). To operate the toy (22) the user moves it and therefore its operation does not require the use of an auxiliary object with specific properties. Electrical charge migration in the toy (22) can cause the balls (12) to form patterns that can be used to play games. When the toy (22) is flipped upside down, the balls (12) can roll on the flat surface (18) located above them, which appear to the user as if the balls (22) are defying gravity. Other embodiments are described and shown.
Abstract:
A system and method for power delivery through a barrier may include a source for directing thermal energy through a first side of a barrier of sufficient intensity to raise the temperature of at least a region of the barrier and propagate therethrough to a second side thereof, and a thermoelectric generator positioned adjacent the second side of the barrier proximate the region to receive the thermal energy from the source and convert the thermal energy into electricity. A method for delivering power through a barrier may include directing thermal energy upon a first side of a barrier, the thermal energy being of sufficient intensity to raise a temperature of at least a region of the barrier and propagate therethrough to a second side thereof, receiving the thermal energy from the source through the barrier adjacent the second side, and converting the thermal energy to electricity adjacent the second side.

Abstract:
One embodiment of a method for producing a plurality of nanostructures embedded in a host comprising the steps of: assembling a first preform, drawing said first preform into a first fiber, cutting said first fiber into a plurality of pieces, assembling said pieces of said first fiber into a second preform, and drawing said second preform into a second fiber. The host is made of a low thermal conductivity material such as a polymer or combination of polymers. The host can assume the form of a plurality of nanotubes which further reduces the host's thermal conductivity due to enhanced phonon scattering. The host can exhibit anisotropic thermal conductivity which reduces its thermal conductivity perpendicular to the direction in which it was drawn. The nanostructure-host composite can be cut into pieces and assembled into efficient thermoelectric devices for use in cooling or electric power generation applications. Other embodiments are described and shown.
Abstract:
An optical phase modulator and modulation method is disclosed. An optical splitter diverts a portion of an input light signal into at least one diverted light signal, and at least one optical amplifier amplifies the at least one diverted light signal to provide at least one amplified light signal. At least one static phase shifter statically phase shifts the at least one amplified light signal to provide at least one phase-shifted diverted light signal, and an optical combiner combines the input light signal with the at least one phase-shifted diverted light signal to provide a phase-shifted combined light signal.
Abstract:
A particular method includes applying light pulses to an optical fiber and receiving backscattered light at a phase-sensitive optical time domain reflectometry (OTDR) device. The backscattered light includes portions of the applied light pulses that are backscattered by the optical fiber. The method also includes determining a difference between the backscattered light and a backscatter pattern associated with the optical fiber. The method also includes determining a communication signal encoded in the backscattered light based on the difference, where the communication signal is encoded in the backscattered light responsive to mechanical waves applied to the optical fiber at a location remote from the phase-sensitive OTDR device.

An electric power generation system employs a thermoelectric generator placed between an aircraft inner skin and an aircraft outer skin. The thermoelectric generator is configured to utilize a thermal differential between the inner and outer skin to generate electricity. An electrical interface is provided for access to the electricity generated by said thermoelectric generator.
Abstract:
An apparatus (e.g., a communication assembly) includes a waveform detector operable to detect a waveform. The apparatus also includes a membrane encircling the waveform detector. The membrane has a first portion that is at least partially transparent to the waveform and has a second portion that is at least partially reflective of the waveform. The apparatus also includes a support member coupled to the waveform detector. The support member is configured to moveably support the waveform detector within the membrane at a location that enables the waveform detector to detect a portion of the waveform that is reflected by the second portion of the membrane.

Abstract:
A particular method includes directing wave energy toward a collection region inside a collector by receiving the wave energy from outside the collector through an at least partially transparent portion of the collector and reflecting the wave energy toward the collection region using an at least partially reflective portion of the collector. The method also includes receiving the wave energy at a receiver disposed in the collection region.
