When needed, the sharp edge protector can be moved so as to expose the sharp edges, allowing the flashlight to be used as a weapon. The protectable sharp edges can also be positioned around the tail end of the self-defense flashlight.Type: GrantFiled: January 29, 2008Date of Patent: March 30, 2010Assignee: PentagonLightInventor: John Huang

Patent number: 7674003Abstract: An electrical switch comprises first and second switch elements including respective first and second electrically conductive flexible domes for selectively making electrical connections. The second switch element is disposed adjacent the first switch element with an electrical conductor therebetween. An actuator is movable for exerting force on the second switch element via a spring, and for exerting force on the first switch element via the spring and the second switch element. The second flexible dome may have an actuating force that is less than the actuating force of said first flexible dome.Type: GrantFiled: April 12, 2007Date of Patent: March 9, 2010Assignee: Streamlight, Inc.Inventors: Raymond L. Sharrah, Peter J. Ziegenfuss, Mark W. Snyder

Publication number: 20100033961Abstract: A handheld searchlight for producing a high intensity beam of light output has an elongated housing including a handle portion for gripping by a user. A head has a window opening for transmitting a light beam. There is a mechanical coupling between the housing and the head. A parabolic reflector is mounted in the head facing the window and has an aperture for accommodating a high intensity lamp. The reflector has a longitudinal optical axis. The rotation of the head about the coupling causes movement of the parabolic reflector relative to the lamp along the optical axis thereby changing a spread of the high-intensity light beam. The searchlight further includes a rotatable bezel ring mounted on the head and a filter ring mount connected to the rotatable bezel. An optical filter is mounted in the filter ring mount.Type: ApplicationFiled: August 7, 2008Publication date: February 11, 2010Applicant: Xenonics Holdings, Inc.Inventors: Gary Palmer, Jeffrey Kennedy
