Abstract: A short wavelength visible light-emitting toothbrush with an electronic interlock control device preventing operation when the toothbrush is removed from the user's mouth. The electronic interlock control over operation is necessary to prevent accidental eye exposure to the high intensity light source with a wavelength in the range of 400 nm to 500 nm. The light-emitting toothbrush activates upon entering the user's mouth but deactivates immediately when removed, thus protecting the user's eyes from direct exposure to the high power light source contained in the brush head.

Abstract: A short wavelength visible light-emitting toothbrush with an electronic interlock control device preventing operation when the toothbrush is removed from the user's mouth. The electronic interlock control over operation is necessary to prevent accidental eye exposure to the high intensity light source with a wavelength in the range of 400 nm to 500 nm. The light-emitting toothbrush activates upon formation of an electrical circuit between the brush handle in contact with the users hand and the brush head or brush bristles in contact with moisture contained in a human mouth such as saliva or water mixed with toothpaste but deactivates immediately when removed from the mouth, thus protecting the user's eyes from direct exposure to the high power light source contained in the brush-head.

Abstract: An oil pourer includes a spout shell that is configured to be connected with a bottle of culinary oil and a collapsible funnel section connected with the spout shell and moveable with respect to the spout shell between an open position and a closed position. When the funnel section is in the open position, the funnel section and the spout shell define an oil-filling opening. When the funnel section is in the closed position, the funnel section seals against the spout shell to close the oil-filling opening. A method of using an oil pourer is also disclosed.

Abstract: A dish drying rack includes a basin, a side bay pivotally connected with the basin for movement about a side bay pivot axis, and a plate rack pivotally connected with the basin for movement about a plate rack pivot axis. The basin includes a basin floor. The side bay moves between a collapsed position and an extended position. The side bay includes a side bay floor. When the side bay is in the extended position, the side bay floor is positioned with respect to the basin such that water drains from the side bay floor toward and onto the basin floor. The plate rack pivot axis is transverse to the side bay pivot axis. The plate rack is movable between an upright position and a flattened position.
