Provided is a method of booting an electronic device including a host central processing unit and a security module. In one embodiment, the system comprises a vehicle accelerator movable between a maximum speed position and a minimum speed position, and a sensor configured to determine the rate of travel of the accelerator toward the minimum speed position. A keyboard window is displayed on the touch sensitive panel and includes a keyboard having a plurality of user selectable keys. In this regard, the edible films can be utilized to deliver or release the medicaments into an oral cavity, thereby providing effective oral treatment with respect to, for example, oral cleansing and breath freshening. The movable side electrode of the variable capacity capacitor is driven directly by the drive motor so that the impedance matching device is made to be compact and response of impedance matching to a fluctuation of a load impedance such as a behavior of a plasma load is improved, and the life is lengthened and degrees of freedom of installation is widened.
