Abstract: An infant play mat with a flexible central mat portion having a fabric surface that forms a first infant play area and including multiple flexible flaps extending from straight edges of the play mat. The infant play mat has a polygonal perimeter with multiple straight edges, with two of the edges defining a corner therebetween. Multiple flexible flaps extend from a respective one of the perimeter edges and define a fold line. Each flap has an upper flap surface exposed when the flap is extended, and hidden when the play mat is folded at the fold line to cover a region of the central mat portion. The central mat portion and lower surfaces of the flaps together form a second infant play area when the play mat is folded at all of the fold lines. Two of the flaps extend from the two edges to define the corner and are shaped such that, when overlaying the central mat portion, the two flaps do not overlap.

Abstract: This disclosure relates to water treatment devices that utilize photocatalytic oxidation to generate oxidizing agents. A water treatment device is configured to be connected in line between a water supply and a washing machine. Wash water from the water supply passes into the device and through a conduit of the device. A reaction chamber includes an ultraviolet lamp and a catalyst cell for generating the oxidizing agents. The generated oxidizing agents are injected into the wash water as it passes through the conduit. The water treatment device also includes a flow sensor placed in line with the conduit to determine when the device should be activated to generate the oxidizing agents.

Abstract: A child development toy including a box and a set of flexible sheets. The box defines an interior compartment and an aperture extending into the interior compartment through a side of the box. Each flexible sheet has a corner with a bounded slit surrounded by material of the sheet configured to receive the corner of another sheet inserted through the slit. The set of sheets is configurable as a chain of sheets. Each two adjacent sheets of the chain is releasably connected by a connection formed by a corner of one of the two adjacent sheets inserted into the slit of the other of the two adjacent sheets.

Abstract: A child play pitcher-container set includes a pitcher and a container that defines an interior volume and an upper rim. The pitcher includes a base upon which the pitcher is supportable, a side wall, and a handle. The side wall extends from the base and forms a spout extending outwardly to a spout tip at an upper edge of the side wall, the spout having an outer surface defining in side view a slope. The handle is secured to the side wall opposite the spout. The outer surface of the spout defines a notch extending across the spout at an elevation along the slope. The notch is configured to interface with the upper rim of the container during pouring of liquid from the pitcher to the container. The interior volume is sufficient to receive all liquid volume containable in the pitcher with the pitcher upright on a horizontal surface.

Abstract: Described is an air and surface purifying device having a purifying cell structured for maximizing the realized photocatalytic reaction at a photocatalytic surface without using an additional ultraviolet bulb. The purifying cell positions at least three photocatalytic surfaces about a single ultraviolet bulb such that the photocatalytic surfaces substantially encompass the ultraviolet bulb and are saturated by ultraviolet light radiating from the ultraviolet bulb. Because the photocatalytic surfaces are saturated, the potential photocatalytic reaction at the photocatalytic surfaces is fully realized. Stated differently, the realized photocatalytic reaction is maximized. Because the purifying cell maximizes the realized photocatalytic reaction, the purifying cell maximizes the purifying capacity of the photocatalytic surface and, thus, the purifying cell itself.

Abstract: Apparatus for providing activated treated water to washing machines with a water treatment conduit connected between a water supply and an inlet of the washing machine, having a reactor chamber with a UV lamp and a coated metal target that generates oxidizing gases that communicate by an injector into the conduit and a transparent portion of the conduit treats the oxidated water by illumination from the UV lamp. A disinfector injects disinfecting silver ions into the treated oxidated water. A controller activates the apparatus during flow of water through the conduit. A method of activating and treating water for washing machines is disclosed.
