The ultracapacitor may supply power to a grid via the inverter during a reduction of power or a loss in power from the grid.

A multi-layer substrate apparatus includes a first layer configured to provide at least one electrical-based property. A second layer proximate to the first layer is configured to provide at least one mechanical-based property.

An aircraft that includes torque rotor and a lifting rotor, and generates torque from the torque rotor. The torque rotor may optimize drag production while the lifting rotor may optimize lift production limiting compromise between drag and lift production rotor.

A hybrid-like liquid fuel motor (the "motor") may include a port surrounded by a wall. Surrounding the wall are a plurality of chambers and segmented walls to separate the chambers. In some instances, a single helix chamber may surround the wall, and may operate similar to that of a segmental chamber.

A system includes a computing device that generates at least one process script for the modification to a glass ceramic substrate and at least one pattern script that corresponds to the process script. The computing device also merges the process script with the pattern script and generates a plurality of command signals that are based on the merged process and pattern scripts.

Satellite navigation receivers are provided herein. In certain embodiments, a satellite navigation receiver correlates a received RF navigational signal from a satellite with a replica code generated by the receiver.

A signal-of-interest (SOI) may be separated from interference and/or noise using repeated reduced rank minimum mean-square error Fractional Fourier Transform (MMSE-FrFT) filtering and a low rank adaptive multistage Wiener filter (MWF).

A speckle-enhanced discrete Fourier transform spectrometer can include waveguides configured to combine speckle spectroscopy techniques with discrete Fourier transform spectroscopy techniques. A discrete Fourier transform spectrometer section can be a compact, passive, chip-scale optical spectrometer. A speckle spectrometer section can include a multi-mode wave guide.

An aircraft for generating torque. The aircraft includes a motor coupling a lifting rotor and a torque rotor, and is configured to spin the lifting rotor in a first direction to generate lift and spin the torque rotor in a second direction to generate drag-torque.

An artificial intelligence (AI) system is disclosed that employs windowed cellular automata to create plausible alternatives. A cellular automata-based technique may be utilized to perform pattern recognition and assess the best path available (i.e., "instant improv"). Alternative sequences (i.e., "pattern improv") may also be used to determine alternative paths.

A rotary positioning apparatus can adjust the rotational position of a device to be aimed about a desired axis. It can include an device mount that includes the aimed device. A motor can be coupled to the device mount or a shaft extending from the device mount to generate a rotational force to rotate the device mount.

A space transport system includes one or more cyclers orbiting between a first planetary body and another planetary body. The space transport system also includes one or more taxi vehicles, each of which carry cargo, humans, or both.

Artificial intelligence (AI) techniques that map disallowed states and enable access to those states under certain conditions through a search algorithm are disclosed.

A narrowband AJ signaling system includes an AJ processor placed between a high precision analog-to-digital (ADC) converter and a narrowband digital receiver. In another example, the AJ processor is placed between the high precision ADC and a digital-to-analog converter (DAC).

A vehicle comprising a structure, a plurality of heating sources, and a transport mechanism. The structure is comprised of multiple materials, a composite such that some of the material constituents can be extracted leaving behind others via application of energy (such as de-alloying). The extracted material or materials are configured to be re-purposed into a propellant.
