摘要:
Disclosed are an apparatus and method for controlling a radiation direction of a small sector antenna, used for a small wireless transmission device having limited power and calculation capabilities, capable of operating at a low power consumption with the necessity of simple calculation capabilities or without the necessity of even a few calculation capabilities. The apparatus for controlling a radiation direction of a small sector antenna includes a plurality of capacitance blocks including a plurality of capacitors each having one end commonly connected to corresponding parasitic elements and having a different capacitance. Capacitors having a capacitance corresponding to a radiation direction are selectively connected to corresponding parasitic elements through a plurality of switching units and a controller, thereby simplifying controlling and reducing power consumption for controlling the radiation direction.
摘要:
The present invention relates to a composition comprising a bamboo plant extract for the prevention and treatment of inflammatory or blood circulation disease. The extracts of bamboo plant has potent anti-inflammatory activity by inhibiting NO production and blood circulation-improving activity by inhibiting elastase activity and healing the wound of vascular endothelial cell, activating u-PA expression and inhibiting PAI-1 expression, lowering cholesterol deposit and inhibiting neointima formation, therefore it can be used as a therapeutic or health care food for treating and preventing inflammatory or blood circulation diseases.
