Abstract: Apparatus and methods directed to a hand holdable flashlight having a grooved rear cap for being secured to an object, through utilization of an interface device securable to the rear cap and to the object. The grooved rear cap also implements securement of a removable guard for protecting a rear end switch actuator from being accidentally actuated in situations when the flashlight is not secured to the interface device.

Abstract: An apparatus and method for easily, quickly and reliably attaching a noise suppressor or other auxiliary device to the muzzle end of a firearm barrel, and in particular to a flash suppressor affixed to the muzzle end of the firearm, and for easily, quickly and reliably removing the noise suppressor or other auxiliary device therefrom.

Abstract: An accessory mount for a firearm having a longitudinal barrel, a first support and a second support forwardly of the first support.

Abstract: An anti-vandal door lock apparatus in which a cylinder lock such as a mortise lock cylinder is employed for unlatching a cylindrical lock assembly. In a preferred embodiment, the mortise lock cylinder is mounted to the outside of a door trim such as a pull plate, with the cylindrical lock mounted to the inside of the trim, and the pull plate is mounted to the door, in such manner as to effect an anti-vandal door lock assembly. Preferred embodiments may include a hold-back feature, as well as a feature for facilitating secured removal of the mortise lock cylinder as for re-keying.

Abstract: Flashlights having selectively controllable brightness levels, preferred embodiments of which comprise in combination: a battery; a switch having an OFF position not connected to the battery, a first ON position connected to the battery, and a second ON position connected to the battery; an electrical component (such as a resistor or an inductor) in circuit with the battery when the switch is in its first ON position and not in circuit with the battery when the switch is in its second ON position; a light emitter assembly; and a controller in circuit with the battery, the switch and the light emitter assembly, for detecting whether or not the electrical component is in circuit with the battery when the switch is in either one of its first ON position and its second ON position, and for controlling electrical power to the light emitter assembly for producing a first light output when the electrical component is detected and for producing a second light output when the electrical component is not detected.

Abstract: Double-sided sleeves and album pages for holding flat items such as compact discs or photographs, including an embedded synthetic paper strip with exposed write-on areas in respective positional association with the pockets of the sleeve or album page.

Abstract: An accessory mount for a firearm, and a method for installing the accessory mount to the firearm.

Abstract: A light beam modifier device for attachment to a light beam generator apparatus such as a flashlight or a weapon light. The light beam modifier includes an easily operable clamp for facilitating securement and removal of the light beam modifier device to and from the light generator. The device provides a positive locking closure between the flip-open door and the clamp, and further includes a spring hinge for permitting at least one and preferably two flip-open positions of the door out of the path of the light beam.

Abstract: Apparatus and methods directed to a hand holdable flashlight including a battery housing having an undercut groove to which is removably fitted a head of an interface device which itself is removably securable to the object.

Abstract: A match number game for being played by a single player or by a plurality of players, preferably at video terminals.

Abstract: Apparatus and method for adjusting orientation offset of a light source housing of a light beam generator mounted to a firearm, in such manner as to preclude inadvertent rotational displacement of the light source housing. The apparatus includes a coupler secured to the light source housing and adapted for being longitudinally placed for interfacing with and fastenable to the battery housing for incrementally adjusting orientation offset of the light source housing.

Abstract: An apparatus and method for concealing a loudspeaker, in which frame modules simulating books are juxtaposed for forming a housing for the speaker. The housing appears as a row or stack of books, and the quantity of frame modules or simulated books may be adjusted for accommodating speakers of different widths or heights.

Abstract: Accessory mounts for firearms, including a combined handgrip and accessory mount for a shotgun, as well as detachably securable rails and modified Picatinny rails for mounting accessories to shotguns and other firearms.

Abstract: A firearm illuminator for selectively providing low intensity illumination to assist the firearm user to navigate his or her surroundings in dark environments, as well as for selectively providing high intensity illumination of a target. The preferred embodiment includes a vertical handgrip having a battery compartment in the handgrip. A battery retainer cap assembly for the battery compartment includes a battery enable/disable mechanism and a safety latch is provided on the handgrip or battery housing for assuring the retainer cap assembly's secure attachment to the battery housing.

Abstract: An electrical appliance having a removably securable switch device, a preferred embodiment of which is an illumination apparatus for being mounted to a firearm and which includes a switch device mechanically and electrically removable from an illuminator device. The removable switch device preferably includes two momentary switches which, when the switch device is mechanically and electrically secured to the illuminator device, may be manually actuated for causing energization of either of two light sources or of both light sources simultaneously.
