摘要:
Various structures are provided that may be advantageously used in one or more illumination device designs. In one example, a lens is movable among a plurality of light sources to facilitate selection of which light source is used to provide light for the illumination device. In another example, electric power is provided only to the light source that is used to provide light for the illumination device. Rotation of a bezel of the light source can determine which light sources provides light for the light source and which light source receives electric power.

A firearm sound suppressor (10) includes a housing (12) and an interior member (32). The interior member (32) is disposed within the housing (12) so as to define a chamber between an exterior surface of the interior member (32) and an interior surface of the housing (12). The interior member (32)includes a lumen (144) and a plurality of vents (146) extending through the interior member between the lumen (144) and the chamber. The firearm sound suppressor (100) also includes a blast deflector (148) disposed between the vents (146) and the interior surface of the housing (112). The blast deflector (148) is adapted to prevent the combustion gases from impinging directly on the interior surface of the housing (112).

Various techniques are provided for firing blanks from firearms. In one example, a blank firing adapter includes a mount assembly operatively configured to be attached to a muzzle of a firearm. The blank firing adapter also includes a main body having an interior chamber. The blank firing adapter also includes an escape port positioned longitudinally forward of the interior chamber and not in communication therewith. The blank firing adapter also includes a barrier interposed between the escape port and the interior chamber. The blank firing adapter also includes a projectile receiving area positioned longitudinally forward of the escape port and configured to slow down a projectile from the muzzle therethrough.

Various techniques are provided for implementing a variable control for a lighting device, such as a flashlight, that uses a variable inductor. The lighting device may include a tail cap, a battery terminal, and a variable inductor mounted in the tail cap and electrically connected in series with the battery terminal. The lighting device may also include a user operable switch configured to selectively bypass the variable inductor. The variable inductor may include, for example, a magnetic coil comprising a wire coil and a core. The variable inductor may also include a ring comprised of ferrous material and having a substantially elliptical inner circumfery and surrounding the magnetic coil, wherein the ring is adapted to be rotated relative to the magnetic coil in response to user actuation of a rotatable user control.

摘要:
A live-fire simulation system uses a position sensitive detector (PSD) in a weapon- mounted sensor (105) to intercept emitted light from target emitters (110) spatially distributed about a target (115). Each target emitter (110) is modulated with a unique frequency. The system can thus not only determine the points of interception on the PSD but also determine which emitter (110) caused which interception by using a frequency analysis.
摘要:
Various techniques are provided for implementing a lighting device variable control using a variable inductor. In various examples, the variable control may be implemented with a plurality of continuous or stepped settings. The variable control may be adjusted by a user-actuated movement of a part of the lighting device, such as the depression of a tail cap or another appropriate physical control to change the inductance of the variable inductor. An oscillating signal may be induced in a variable inductor circuit that includes the variable inductor. The oscillating signal may exhibit characteristics, such as frequency, that change with the inductance of the variable inductor. Such characteristics may be measured to determine a setting of the variable control and which may be used to adjust the brightness or other attributes of the lighting device.
摘要:
A user wearable device may be implemented with a light source to provide illumination to an area of interest. In one example, the light source may be selectively operated by switches, physical displacement (e.g., movement) of the device, or other approaches. In another example, the device may be implemented as a wristwatch to display time, date, or related information to a user. In another example, the device may be implemented with appropriate processing or communication components to perform other tasks. In other embodiments, various methods of using, operating, or manufacturing such devices are provided.
