  • Patent number: 11847084
    Abstract: CMOS output stages, electrostatic discharge (ESD) protection circuits and input bus-keeper functions are provided that block dc and ac leakage paths within inactive powered-down integrated circuits used in redundant high-reliability system configurations employing cold-sparing to provide backup circuitry. These circuits and methods avoid both undesirable power consumption in a cold-spared backup unit and loading of connected active units when powered down, without compromising performance or functionality of the backup unit when in its active powered state. Inputs and outputs using an analog majority voting principle to implement in-circuit redundancy for on-chip fault tolerance are also provided, incorporating the low-leakage principles of the invention for low power dissipation when powered down. Such on-chip redundancy can harden an IC against various faults, such as single-event effects in high-radiation environments, while maintaining the other advantages in a cold-sparing system.

  • Patent number: 11825573
    Abstract: In an auto vibrancy mode, a vibrancy value for a lighting load may be automatically determined based on a selected color setting for the lighting load. The automatically determined vibrancy value may also be configured to emit light from the lighting load at or above a target CRI value for the selected color setting. The selected color setting may be a CCT value on the black-body curve or an x-y chromaticity value. If the selected color setting is CCT value on the black-body curve, the automatically determined vibrancy value may be a pre-defined vibrancy value that is configured to emit light from the lighting load at or above the target CRI value for the selected CCT value. If the selected color setting is an x-y chromaticity value, the automatically determined vibrancy value may be based on the distance between the selected x-y chromaticity value and the black-body curve.

  • Patent number: 11815789
    Abstract: Introduced here are light sources for flash photography configured to produce high-fidelity white light that is tunable over a broader range of correlated color temperatures (CCTs) than conventional flash technologies. The light source can include multiple independently controllable color channels representing illuminants (e.g., light-emitting diodes) of different colors with varying degrees of saturation. Operating collectively, the multiple color channels can produce a high spectral quality white light corresponding to different CCTs (e.g., “warm” white light having a red hue, “cool” white light having a blue hue). Operating independently, these same color channels can be pre-flashed in a variety of prescribed sequences to probe the spectral characteristics of a scene, thereby allowing for an enhanced, spectrally matched white flash as well as collecting per-pixel reflectivity data that can be later used in during post processing of the captured image.
