Provided herein are energy storage devices. In some cases, the energy storage devices are capable of being transported on a vehicle and storing a large amount of energy. An energy storage device is provided comprising at least one liquid metal electrode, an energy storage capacity of at least about 1 MWh and a response time less than or equal to about 100 milliseconds (ms).

Electrochemical energy storage devices

Thermal management of liquid metal batteries

According to various aspects, a sensor system is provided comprising a first substrate configured to be coupled to a user, an electric field detector to detect a user electric field and comprising a second substrate, a proof mass positioned above the second substrate, one or more electrodes coupled to the second substrate, and a control circuit coupled to the one or more electrodes, the control circuit being configured to determine a change in capacitance between the proof mass and each electrode responsive to torsional movement of the proof mass responsive to the electric field, and a controller coupled to the first substrate and being configured to receive, from the detector, information indicative of each change in capacitance between the proof mass and each electrode, and determine, based on the information, characteristics of the electric field in at least two dimensions.

Miniature electric field detector

A multi channel beamsplitter system operating over a wide spectral band has high optical performance despite the fact that the incoming and/or exiting light is not collimated and its material is dispersive. This is achieved using wavefront compensators that are matched to the curvature of the wavefronts of the incoming and/or exiting light.

Multi-channel optical system

According to various aspects and embodiments, a growth adaptive expandable stent is provided. The expandable stent includes a stent structure having a cylindrical shape that is self-expanding in a radial direction and includes a plurality of cylindrical rings disposed along a longitudinal axis of the stent structure. The stent structure is configured to exert a continuous outward radial force over time when implanted such that a diameter of the stent structure expands from a first value to a second value that is at least about 1.5 times the first value.

Growth adaptive expandable stent

A potentially small, gimballed, multi-sensor system employs a shared aperture for at least some of the image sensors. Applications include intelligence, surveillance, target acquisition and reconnaissance (ISTAR), and guiding autonomous vehicles. The system can actively blend images from multiple spectral bands for clarity and interpretability, provide remote identification of objects and material, provide anomaly detection, control lasers and opto-mechanics for image quality, and use shared aperture using folded optics.

Compact multi-sensor fusion system with shared aperture

Aspects are generally directed to a compact and low-noise electric field detector, methods of operation, and methods of production thereof. In one example, an electric field detector includes a proof mass, a source of concentrated charge coupled to the proof mass, and a substrate having a substrate offset space defined therein, the proof mass being suspended above the substrate offset space. The electric field detector further includes a sense electrode disposed on the substrate within the substrate offset space and proximate the proof mass, the sense electrode being configured to measure a change in capacitance relative to the proof mass from movement of the proof mass in response to a received electric field at the source of concentrated charge. The electric field detector includes a control circuit coupled to the sense electrode and configured to determine a characteristic of the electric field based on the measured change in capacitance.
