Abstract: A system, method and communication device are disclosed for organizing and presenting a plurality of digital flyers. Using flyer stack information, which organizes the plurality of digital flyers into at least one flyer stack, the plurality of digital flyers are presented to allow for inter-flyer and intra-flyer navigation. Moreover, the flyer stack information may be used to allow the inter-flyer and intra-flyer content to be searched. This is achieved by providing a method and communication device that receives the flyer stack information from a server, and presents the flyer stack information in a flyer navigation interface.

Abstract: A system for contextualizing a digital flyer is disclosed. The system includes a polygon mapping module for incorporating contextual information in the digital flyer using polygon mapping information, the polygon mapping information comprising a polygon for defining a polygonal area on a source flyer image of the digital flyer, the polygon being tagged with the contextual information, and a flyer data store for storing the tagged polygon. There is also disclosed for displaying the contextualized digital flyer and generating feedback using the contextualized digital flyer.

Abstract: An interactive flyer system is disclosed. The system includes a flyer image tiler for creating a flyer image tile set, the set including multiple copies of a flyer image segmented into a plurality of flyer image tiles with each copy representing the flyer image at one of a plurality of zoom levels, wherein a copy of the multiple copies is configured to fit within a viewport having a resolution, and a flyer image tile store for storing the flyer image tile set. There is also disclosed a method for displaying the interactive digital flyer.

Abstract: In the present disclosure, there is disclosed a communication device including a pre-loading module configured to retrieve a first and a second set of flyer image tiles from a flyer image tile set stored in memory, the first set of flyer image tiles being associated with the most zoomed-out state and the second set of flyer image tiles being associated with a zoom level of a current viewport. The pre-loading module is further configured to associate the first set of flyer image tiles with an underlay viewport. The communication device further includes a display configured to display the first set of flyer image tiles in the underlay viewport that are visible in the current viewport and overlay the second set of flyer image tiles visible in the current viewport onto the first set of flyer image tiles.

Abstract: A handheld, battery-operated ultraviolet sterilization device having a cold cathode ultraviolet lamp enclosed in a protective chassis. The cold cathode ultraviolet lamp is a low voltage lamp and the power supplied by two AA batteries provides hours of lamp operation.
