Abstract: A reclosure article is configured for permanent attachment to a flexible container. The article includes a resilient, elongated strip including first and second fasteners proximate each of two opposed ends, wherein at least the first fastener includes a slot configured to receive one of first and second opposite side edges of the flexible container. A method is described for closing a flexible container using a reclosure article that is permanently attached to the container. The method includes inserting one of first and second opposite side edges of the flexible container into a slot of the article.

Abstract: An ergonomic handle may include an approximately straight section configured to be grasped by one or more of a user's index finger, middle finger, and/or ring finger. The ergonomic handle may further include a widened section that may include an inward curve and a concave curve. The remaining fingers of the hand which may include the middle finger, ring finger, and/or little finger may push against the widened section when the hand is holding the ergonomic handle. The widened section, inward curve, and concave curve may all assist the user in allowing the user to hold the ergonomic handle in a natural hand position. The widened section may allow a larger area for the remaining fingers to push against and the inward curve and concave curve may align with the natural shape of the user's fingers making the ergonomic handle more comfortable to use.

Abstract: An air inlet duct connected to an air inlet of a burner assembly of a water heater system includes an outlet connected to the air inlet of the burner assembly, a duct inlet for receiving air, a main conduit connecting the duct inlet and the outlet, a branch connected to the main conduit, and a pressure relief mechanism connected to the branch. The pressure relief mechanism opens when the main conduit reaches a predetermined pressure value. The air inlet duct is adapted to mitigate effects from leaks that develop in the water heater system.

Abstract: A retrofit infuser may be configured to be used with a drinking container to allow material, held within the infuser, to be infused within a liquid of the drinking container. The material may be fruits, vegetables, teas, coffee beans, coffee grounds, or other food and drink related items. The infuser may include a lid. The lid may be configured to removably secure the infuser within a neck of the drinking container or to float atop a liquid in the drinking container. The infuser may include a cage configured to hold the material to be infused and to allow the material to be infused into the liquid of the drinking container. The cage may be configured to be removably secured within the lid of the infuser. The infuser may further be configured to removably secure to a straw of the drinking container.

Abstract: A system and method for configuring a water heater. The method includes capturing, with a mobile device a scannable feature of a rating plate, establishing a network connection between the mobile device and a server, transmitting information captured from the scannable feature by the mobile device to the server over the network connection, receiving from the server to the mobile device a plurality of water heater configurations in response to the information, receiving, with the mobile device, an input indicative of a configuration selection selected from the plurality of water heater configurations, and transmitting configuration information from the mobile device to the water heater to configure the water heater based on the configuration selection.
