Abstract: A bathtub closure system may include a step configured to be retrofit onto a bathtub and a plug. The step may include a first side panel, a second side panel, and an elongated platform defining a cavity configured to facilitate ingress and egress into the bathtub, and a first attachment recess extending downward from the first top surface less than an entire height of the first side panel or extending downward from the second top surface less than an entire height of the second side panel. The plug includes a body and a first attachment member affixed to the body and corresponding to the first attachment recess defined by the step. The plug cooperates with the step to form a substantially watertight seal when the first attachment member is mated with the first attachment recess and the body of the plug is positioned at least partially within the cavity.

Abstract: Systems and related methods are disclosed for characterizing physical phenomena. In an embodiment, the system includes a frame defining an active volume, a camera configured to capture an image of the active volume, and a controller coupled to the camera. In an embodiment, the controller is configured to: track an object within the active volume via the camera, analyze a motion of the object within the active volume, and output a visual depiction of the object and one or more vectors characterizing the motion of the object on a display.

Abstract: Embodiments described herein include a bathtub closure system having a step, the step having a first side panel, a second side panel, and an elongated platform defining a cavity, where the cavity can be configured to facilitate ingress and egress into a bathtub. The bathtub closure system can include a closure, where the closure can be coupled with the step and can cooperate with the step to form a substantially watertight seal when the closure is in a closed position. The bathtub closure system can include a support portion, where the support portion can be co-molded with the step and have a substantially U-shaped configuration extending in a generally downward direction from the step to support the step during use.
