Abstract: A motion recognition device includes a sensing unit and a processing unit. The sensing unit generates a sense signal in response to a body motion occurring at a specific position on a user's body, wherein the sense signal includes a first sense signal portion and a second sense signal portion different from the first sense signal portion, and the body motion belongs to a motion segment of a motion type. The processing unit processes the sense signal to generate a motion parameter signal structure including a fusion signal of the first and the second sense signal portions, and recognizes the specific position to determine an effective reference signal for recognition of the motion type based on the motion parameter signal structure.

Abstract: A photosensitive porphyrin-based dye is adapted to be used in a photoelectric converting device such as a dye-sensitized solar cell. The photosensitive porphyrin-based dye has a porphyrin center, at least one electron donor unit, at least one electron acceptor unit and an optional blocker unit wherein the units are directly connected to the porphyrin center or connected to the porphyrin center via ethynyl-bridges. The photosensitive porphyrin-based dye having a structural formula (I): where D represents an electron donor unit, A represents an electron acceptor unit and P represents a blocker unit.

Abstract: This invention provides a dynamic heat conduction system comprising a base, a resilient unit, a heat conduction block, and at least one securing unit. The base accommodates the resilient unit and the heat conduction block and the at least one securing unit secures at least a portion of the base and the resilient unit within the base. The heat conduction block comprises a heat conduction surface for forming a contact with an electronic device and accomplishes preferably efficient heat conduction by conducting the heat produced by the electronic device through the heat conduction surface, the heat conduction block, and a side surface of the heat conduction block to the base. Still, this invention provides a dynamic heat conduction system comprising a heat conduction board for accommodating a plurality of heat conduction blocks and a plurality of bases for forming a preferable heat conduction path with a plurality of electronic devices having different shapes or sizes.
