Abstract: The present invention relates to a method and system for identifying templates or forms for interpreting data input thereto on an interactive device in communication with one or more mobile devices. The interactive device comprises template overlay, having an identifiable feature, is aligned with an interactive surface. The mobile device has a reader that reads the identifiable feature and produces a template identifier that is retrieved from a content server. Input into the template overlay is recognized and interpreted into labels or equations. Subsequent input is then automatically calculated using the equation.

Abstract: An electric saw device includes a first saw blade and a second saw blade. The first and the second saw blades are respectively driven by a small transmission shaft and a large transmission shaft to rotate in opposite directions. A round rib is disposed on an inner end surface of the first saw blade, and at least three recessed holes are arranged in a top end surface of the round rib at equal angle intervals. A steel ball is accommodated in each of the recessed holes, and protrudes out of the recessed hole. Protruding ends of the steel balls urge against an inner surface of the second saw blade, so as to limit a distance between the first saw blade and the second saw blade, and form a rolling friction when the first and the second saw blade rotate in the opposite directions. Further, a power output shaft of the electric saw device is joined with the small transmission shaft of the first saw blade through a key connection structure, so as to ensure that the saw blades do not tilt after installation.

Abstract: An electric heating wire and applications thereof with the electric wire consists of a core made from a plurality strands of graphite fibers. The core is wound by an oblate insulation layer which has two wing flaps on the left and right sides for stitching and anchoring use. The core of the electric wire that consists of graphite fiber can generate heat when energized. The electric wire thus made may be anchored on blankets quickly to form an electric blanket, and can prevent rupture resulting from fatigue caused by temperature variations. The electric wire and the electric blanket thus formed have improved safety when in use and have a greater durability.

Abstract: An electrically heating cable of the invention comprises a central core formed from the assembly of a plurality of graphite fibers. The central core is covered with a nylon layer. Around the nylon layer is wound a temperature sensing wire made of nickel in a helicoid manner. Ultimately, the electrically heating cable is encapsulated within an insulating layer made of polyvinyl chloride. Thereby, the electrically heating cable is provided with a sufficient toughness and flexibility to prevent cracks and ensure a safe use.

Abstract: A heating substrate useful in an electronic blanket or a hot compressing pad is provided. The heating substrate includes a flexible fiber layer and a graphite thread. The graphite thread is wound on the flexible fiber layer with a given winding distance. The graphite thread is stitched onto the flexible fiber layer by use of a positioning wire. A slot is formed appropriately on the flexible fiber layer for forming a given number of the graphite threads and the layer thereunder as a unit of the heating substrate of the invention. Thereby, the thick flexible fiber layer is prevented from being distributed unevenly when in use.
