Abstract: Methods and systems for creating, storing, transferring and manipulating electronic data layers employ computer hardware and software including instructions embodied in program code encoded on machine readable medium to provide, for example, one or more first layers of electronic data and one or more second layers of electronic data associated with a predetermined portion of the first layer of electronic data. The first and second layers of electronic data are stored independently of one another on the same or different databases, and the first layer of electronic data can be accessed and presented by a viewer application on a client device together with the second layer of electronic data in association with the predetermined portion of the first layer of electronic data.

Abstract: Methods and systems for annotation documents are disclosed. For example, a method for annotating a document includes creating a collaboration, adding a document to the collaboration, adding a user to the collaboration, selecting the document, creating an annotation, associating the annotation with the document, and storing the annotation on a processor-based device.

Abstract: An elastic dog leash and coupler utilizes brightly colored florescent latex tubing for a major portion of the leash and coupler. The tubing is mounted between rings. A monofilament nylon line is mounted within the tubing and connected to the rings. The monofilament line has a length significantly greater than the unstretched length of the tubing, and limits the degree to which the tubing may be stretched. With respect to the leash, a nonstretchable webbing handle is attached at one end and a stop section of the leash is attached at the other end. The coupler is comprised of a plurality of sections of tubing mounted to a ring, which may be attached to the end of the leash. The other ends of the tubing of the coupler are provided with nonstretchable webbing material which may be utilized as a stop section for the coupler leash. The webbing material may be provided with a reflective stripe for additional safety at night.
