Abstract: Techniques are described for operating an optical system. In some embodiments, light associated with a world object is received at the optical system. Virtual image light is projected onto an eyepiece of the optical system. A portion of a system field of view of the optical system to be at least partially dimmed is determined based on information detected by the optical system. A plurality of spatially-resolved dimming values for the portion of the system field of view may be determined based on the detected information. The detected information may include light information, gaze information, and/or image information. A dimmer of the optical system may be adjusted to reduce an intensity of light associated with the world object in the portion of the system field of view according to the plurality of dimming values.

Abstract: An automatic basting apparatus is provided. The apparatus has a base that defines a cavity. A basting fluid dispensing member is present and defines a passageway in communication with the cavity. The basting fluid dispensing member is rigid. The basting fluid dispensing member is configured for dispensing basting fluid out of an outlet of the passageway at an end of the basting fluid dispensing member. The outlet is oriented to have a component in both the horizontal direction and vertical direction.
