It is an object of the present invention to maintain high brightness of output light while ensuring sufficient color reproducibility in a liquid crystal display device. The video surveillance system including at least two sensing units. A second end of the microstrip is coupled to a second varactor diode. By repeatedly pulling the bottom surface of the pliable member across the hair tangentially to the surface of the person’s scalp, the plurality of spaced-apart bores disposed in the bottom surface cause clumps of hair to be formed at substantially regular intervals that are a function of the distance between ones of the spaced-apart bores. The compounds provided herein are useful in treating obesity, osteoporosis and in improving muscle mass and muscle strength. A method within an adhoc mesh network for two devices to quickly determine roles while establishing a security association is provided for.
