US Classification:

705 1

Abstract:

An advertising service divides a consumer transaction at a POS location into multiple time frames. The service then determines an advertisement (ad) for display in one of the time frames and displays the ad in one of the time frames. One of the time frames spans one of the following activities: waiting for a consumer to begin a transaction, greeting a consumer, beginning a transaction, selecting a form of payment, swiping a card for a form of payment, entering a security code for the form of payment, identifying a product for purchase, displaying a total cost for products identified for purchase, signing for a purchase, thanking a consumer his purchase, surveying a consumer, promoting an event, applying for a credit card, informing a consumer, identifying a consumer, interacting with a consumer, and passing through an interstitial period. Determining the ad for display in one of the time frames includes transmitting information about the transaction to an ad-management service that then determines the ad for display based on the transmitted information. A response indicates the determined ad.

US Classification:

Abstract:

Graphene-based storage materials for high-power battery applications are provided. The storage materials are composed of vertical stacks of graphene sheets and have reduced resistance for Li ion transport. This reduced resistance is achieved by incorporating a random distribution of structural defects into the stacked graphene sheets, whereby the structural defects facilitate the diffusion of Li ions into the interior of the storage materials.

Abstract:

Aspects of the invention are directed to a method for forming a graphene composite structure. Initially, an encapsulating film is formed on a substrate. The encapsulating film comprises graphene. Subsequently, a plurality of particles are deposited on the encapsulating film, and then a temporary layer is deposited on the plurality of active particles and the encapsulating film. The substrate is then removed. Lastly, the temporary layer is also removed so as to cause the plurality of particles to form a cluster that is at least partially encapsulated by the encapsulating film.

Abstract:

In general, in one aspect, a graphene film is used as a protective layer for current collectors in electrochemical energy conversion and storage devices. The graphene film inhibits passivation or corrosion of the underlying metals of the current collectors without adding additional weight or volume to the devices. The graphene film is highly conductive so the coated current collectors maintain conductivity as high as that of underlying metals. The protective nature of the graphene film enables less corrosion resistant, less costly and/or lighter weight metals to be utilized as current collectors. The graphene film may be formed directly on Cu or Ni current collectors using chemical vapor deposition (CVD) or may be transferred to other types of current collectors after formation. The graphene film coated current collectors may be utilized in batteries, super capacitors, dye-sensitized solar cells, and fuel and electrolytic cells.
