Abstract: A method and system for improving security of a mobile terminal can be used to determine whether the obtained slide-to-unlock operation matches with prerecorded slide-to-unlock operation habits of an owner of the mobile terminal, thereby determine whether the current user is the owner, and perform corresponding processing. With this method and system, it is not required to remind a user to input verification information, such that the current user cannot perceive that verification is currently in process. Therefore, the validity of the verification can be ensured and the security of the mobile terminal can be improved effectively.

Abstract: An apparatus and method for covering the optical system of a moving head light fixture with a filter or diffuser when the lighting fixture is turned off is provided. The filter or diffuser is positioned in the optical path between a lighting element and a lens. A retraction device is energized to retract the filter or diffuser from the optical path during normal operation. Upon removal of power to the fixture, the filter mechanism automatically returns the filter or diffuser to its position in the optical path. In this way, the optical system of the fixture can be protected from damage caused by impinging strong light and/or sunlight when the fixture is not in use.
