摘要:
A firearm sound suppressor (50) includes a housing (52) including a front end (54) and a rear end (58). The rear end (58) includes a flange that partially encloses the rear end and defines a rear aperture (60). The firearm sound suppressor (50) also includes a back end member disposed substantially within the rear end of the housing and including a rear surface (64) disposed in abutment with an inner surface (66) of the flange to prevent the back end member from passing through the rear aperture (60).
摘要:
A noise suppressor (1200) for a firearm comprising a front end (1201) and at least one protrusion (1203) extending from the front end (1201). The noise suppressor (1200) can have a plurality of protrusions (1203). For example, a plurality of spikes (1203) can be formed upon the front end (1201) of the noise suppressor (1200). The protrusions (1203) can be configured to be useful for self-defense or other purposes.
摘要:
Various techniques are provided for implementing a lighting device (1100) with selectable output level switching. In one example, a lighting device includes a light source (1115), a controller (1220) adapted to provide one or more signals to control the operation of the light source, a power terminal adapted to receive a power source, and a tailcap assembly (1160). The tailcap assembly includes a tailcap (1190), a push button (1191), and a washer (1170) disposed in the tailcap. The washer includes at least one arm (1171) adapted to be pushed against a surface to selectively connect the controller to the power terminal in response to a manipulation of the tailcap assembly.

Various techniques are provided for programming lighting devices. In one example, a lighting device includes a light emitting diode (LED). The lighting device also includes a microcontroller configured to receive a programming signal generated by the LED in response to illumination of the LED with an externally-supplied light signal modulated with the programming signal.
摘要:
Various embodiments are provided to implement an attachment for a firearm that operates as a flash hider, a muzzle brake, and/or to mount, e.g., a sound suppressor, to the firearm. In one example, a firearm attachment includes a base adapted to couple to a muzzle end of a barrel of a firearm. The firearm attachment includes a plurality of longitudinal tines that extend forward from the base. The base includes a plurality of apertures disposed rearward of the tines and that extend from a bore within the base through an outer circumfery of the firearm attachment. The apertures exhibit a first diameter at the bore and a second larger diameter at the outer circumfery. The apertures are adapted to impart thrust to the firearm attachment in response to combustion gases passed from the bore through the apertures to compensate for muzzle rise associated with the firearm.
摘要:
Illumination devices may be provided with one or more light sources that emit light of the same, similar, and/or different optical spectra within a wavelength range, for example, from the extreme ultraviolet (UV) to the far infrared (IR). One or more of the light sources may be selectively adjusted to control the overall mix of light projected onto a scene of interest. For example, one or more light sources may be used, and sometimes in conjunction with other optical elements, to provide illumination having a particular angular intensity distribution, color temperature, and/or other desired optical properties for a scene within a field of view (FOV) of the camera of a mobile device used for videography and/or photography. One or more illumination devices may also be used as flashlights and/or as sources of electrical power for recharging mobile devices. Related methods are provided.
