A method and system that recognize include capturing a hand image using an imaging device. Two anti-reaction valve devices are provided between two pipes fluidically connected to a hydraulically powered actuator such that directional relationship of connection of primary and secondary ports is reversed between the two anti-reaction valve devices so that a reaction of the actuator is inhibited quickly and reliably. Furthermore, the bio-1-alkenes may be converted to biolubricants useful in the transportation sector and other areas requiring high puritythermally stable lubricants. The projection portions are fit into corresponding guiding slots of the housing, and stoppers are positioned on top surface of the sliding wedge.
