Abstract: A display system for a welding helmet that includes a darkening filter layer, a high-dynamic range (HDR) camera system to capture an HDR light field, and an optical image stabilization subsystem. Captured images are displayed on an HDR electronic display within the welding helmet without risk of overexposure of ultraviolet radiation to the operator. In some examples, dual electronic displays are used to display different HDR images to each eye of the operator.

Abstract: An anti-theft system and method for encoding power for distribution to a load (e.g., a house) and a decoding of the encoded power at the load for consumption. A meter with an integrated decoder may be installed proximate a house (or another load). In some embodiments, the combination meter/decoder system may be configured to replace a traditional meter on a standard service panel, to minimize any impact or changes to the home or other building. In other embodiments, an add-on decoder system may be configured for installation between a standard meter and a service panel (optionally, plug and play). Alternatively, an add-on decoder system may be installed with the meter positioned (electrically) between the add-on decoder system and the service panel of the house (or other type of load or consumer).
