Abstract: A wrist-pose isolation system can infer a wrist pose (e.g., the user's hand position relative to her forearm) and can reduce wrist-induced jitter for projection casting in an XR environment. A user's projection cast can be determined as a combination of a “low-wrist contribution” component (e.g., a body-and-arm component) and a “high-wrist contribution” component (e.g., the pose of the wrist with respect to the arm). Using input from a gesture-tracking system, the contribution of the user's wrist pose to the user's current projection cast is calculated as a “wrist-contribution vector.” A projection cast direction can be determined as the interpolation of the current low-wrist contribution component and the high-wrist contribution component. This interpolation can be performed by weighting each by a specified amount and combining them.

Abstract: Food processing equipment, food contact surfaces, and non-food contact surfaces are sanitized or disinfected using an acid-anionic surfactant solution that has efficacy in hard water, is non-corrosive, and is stable at elevated temperatures. The sanitizing/disinfecting solution is prepared as a highly concentrated liquid and diluted to end use concentrations prior to application to food processing equipment or food or non-food contact surfaces. Efficacy in hard water is important for sanitizers and disinfectants that are diluted by the end user using potentially hard water. Stability at elevated temperatures is important for long-term storage and transportation. The diluted sanitizing/disinfecting solution exhibits strong antimicrobial activity against gram positive and gram negative bacteria even when dilated in hard water. The sanitizing/disinfecting solution exhibits low toxicity to humans and the environment since it is prepared from low toxicity ingredients that are readily biodegradable.
