Abstract: A shock-absorbing package includes a box and a base. The box is configurable to enclose an item and has a box bottom panel. The base has a base bottom panel and defines a recess sized to accommodate a portion of the box including the box bottom panel. The base interfaces with the box in a transport configuration so that the box bottom panel is held separated from the base bottom panel and a volume of air is disposed between the base bottom panel and the box bottom panel. An impact force applied to the base bottom panel generated by dropping the shock-absorbing package onto a surface induces relative movement between the box and the base that expels air from the volume air and decelerates the box at a rate less than a desired maximum deceleration rate.

Abstract: An edible structure may comprise a gelatin film and fiber strips. The gelatin film may have a higher density of gelatin in a first layer of the film than in a second layer of the film. The fiber strips may be attached to the first layer, and may have an initial orientation, thickness and density. The structure may be configured to undergo a shape transformation when the apparatus hydrates. During the transformation, the film may transform from a flat film into a curved, 3D film. Which specific shape results from the transformation may depend, at least in part, on the initial orientation, thickness and density of the fiber strips. The film may include flavorings or other additives. In some cases, the transformation may change a texture of the structure. In some cases, the transformation may be caused, at least in part, by a change in temperature.

Abstract: The invention relates to nano-sized complexes formed by associating or attaching amorphous calcium phosphate (ACP) and/or amorphous calcium fluoride phosphate (ACFP) with an amphiphilic polymer surfactant (APS) and a bioadhesive polymer. The bioadhesive polymer may serve as a connector or an anchor to attach the nano ACP-APS or ACFP-APS to the tooth surface and to chemically bond the calcium in the enamel to the calcium ions in the nano ACP-APS or ACFP-APS complexes, thus allowing for more controlled release of remineralizing components into the oral cavity. Methods of use of the composition and kits are also disclosed.

Abstract: A network computer system selects a service provider for individual order requests by predicting an order preparation time of the respective supplier for the order request. During a time interval that precedes the order preparation time, the computer system matches an arrival time of a service provider to the respective supplier of an order request. The network computer system estimates an order delivery time for the requester based at least in part on the predicted order preparation time and on a location of the supplier relative to a location of the requester.
