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.

The method includes applying a clock signal (of at least 1 GHz) to an electronic element in a location having first electrical properties. Data is output from the first electronic element; and received at a second electronic element located in a location having second electrical properties. The first and second electrical properties are different by either voltage and clock frequency.

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: A composite film includes a substrate that is not responsive to relative humidity, and also one or more layers of hygromorphic material. The hygromorphic material expands in response to an increase in relative humidity and contracts in response to a decrease in relative humidity. In some cases, the composite film is bi-layer or tri-layer. The composite films are fabricated such that they undergo a desired bending pattern in response to changes in relative humidity. In some cases, these bending patterns are combinations of two bending primitives: a smooth curve and a sharply angled curve. These two primitives are combined to create a variety of shape transformations including 1D linear transformation, 2D surface expansion and contraction, 2.5D texture change and 3D folding. Any type of hygromorphic material may be employed, including living gram positive and gram negative bacterial cells, yeast cells, plant cells, mammalian cells, cell debris, or hydrogel.

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: 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: A user and a merchant register an account with a payment processing system and each receive a unique identifier. When the registered user enters a search query for a product, the search engine system locates a product that matches the search query and that is associated with a registered merchant. The search engine system then confirms that the user and the merchant are registered, and creates a unique product identifier for the product. After associating the unique product identifier with the product, the search engine presents the product to the user with a direct purchase option. If the user selects a direct purchase option, the search engine system communicates with the payment processing system and merchant system to facilitate and verify the purchase transaction. The merchant then provides the product to the user.
