Abstract: A delivery door extension that attaches to an existing door jamb and engages with an existing door is provided. The delivery door extension includes a panel having a planar body with opposing front and rear surfaces extending between first and second side surfaces, a top surface, and a bottom surface, wherein the panel body includes an opening. The delivery door extension also includes a delivery window body configured to move between an open position and a closed position, a hinge mechanism attached to the first side surface of the panel, a blocking mechanism on the second side surface that restricts movement of the existing door, and a frame that includes first and second portions.

Abstract: An operating assembly for use with a sink or bathtub having at least one fluid-holding basin and a basin drain includes an actuator and a housing. The housing includes a plug structure at, or near, a bottom portion of the housing for selectively blocking the basin drain and a drain valve comprising an inlet adjacent a bottom portion of the housing controlled by the actuator to be in an open position or a closed position. The inlet of the drain valve is provided on a first side of the housing, and the outlet of the drain valve is provided on a second side of the housing opposite the first side and directs fluid into the plug structure. The plug structure mates with the basin drain to prevent fluid in the basin from escaping into the drain other than through the drain valve.

Abstract: Systems and methods of making and using a sink device fitted with sensors that measure characteristics related to the water cleansing and maintenance of the sink and its turnover and communicate this data to a cloud-based system that automatically or remotely operates mechanisms that control soap dispensation, sanitizer dispensation, liquid level, water temperature and dispensation, water cleanliness (with or without soap or sanitizer in solution) and draining, as required for hospitality regulation compliance. Although three-compartment sinks are the primary subject matter used in the following examples to illustrate the features and functions of the systems and methods, the features and functions provided by the present disclosure may be adapted for use in other sinks, tubs, and the like.
