  • Publication number: 20180195836
    Abstract: A laser sight device for a firearm is provided with a variable power output. In one example, the laser sight device may include a laser assembly configured to provide a laser beam. The laser sight device may include a sensor configured to provide a sensor signal comprising a motion parameter value associated with motion of the laser sight device detected by the sensor while the laser sight device is attached to the firearm. The laser sight device may include a controller configured to provide a control signal to the laser assembly to selectively adjust an intensity of the laser beam in response to the motion parameter value. Additional features and related methods are also provided.

  • Publication number: 20180194021
    Abstract: A handheld lighting device is provided with a detachable knife assembly. In one example, the handheld lighting device may include a light source that generates a light beam to illuminate a scene, such as a work area. The knife assembly may be coupled to the lighting device using an attachment mechanism. The lighting device may include a slot that may receive a sleeve of the knife assembly such that the knife assembly may be secured to the lighting device. The lighting device may illuminate the work area such that a user may readily see the area that a knife of the knife assembly may cut. The light source of the lighting device may be activated using a multi-access user control that may be L-shaped and actuated from one or more locations on the user control. Additional features and related methods are also provided.

  • Patent number: 9618827
    Abstract: 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.

  • Patent number: 9593912
    Abstract: A live-fire simulation system uses a position sensitive detector (PSD) in a weapon-mounted sensor to intercept emitted light from target emitters spatially distributed about a target. Each target emitter 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 caused which interception by using a frequency analysis.

  • Publication number: 20160209025
    Abstract: A lighting device attachment for a mobile device may include a housing that defines a cavity or an external coupling member configured to receive the mobile device, a light source within the housing, and an optical element adapted to project light from the light source to illuminate an external scene. The attachment may include multiple light sources and multiple associated optical elements to generate a combined beam for illuminating the external scene which may include the field of view of a camera of the mobile device. The camera and the light sources may be cooperated to capture still or video images. The attachment may include a battery that provides power to the light sources and/or the mobile device and may charge a battery of the mobile device. The light sources may be operated by a control device of the attachment and/or by the mobile device. Related methods are provided.

  • Publication number: 20160209001
    Abstract: A lighting device may include a light source and a reflective optical element. The reflective optical element may have a reflective internal surface that defines a cavity. The internal surface may include longitudinal undulations. The internal surface may be faceted or non-faceted. The light source may be at least partially disposed in the cavity. The shape profile of the internal reflective surface in any plane containing the surface's symmetry axis may be non-paraboloidal and may exhibit undulations running along its length. The reflective optical element may be a monolithic structure and may be a beam-shaping reflector that generates a light beam that, in comparison with a paraboloidal reflector having the same hole size, aperture size, and light source, is relatively fainter at small off-axis angles, brighter at mid-range off-axis angles, and fainter at large off-axis angles than a light beam generated by the paraboloidal reflector. Related methods are provided.

  • Patent number: 9189537
    Abstract: Some embodiments of extraction of critical information from a database in a networked system have been presented. In one embodiment, a subset of data from the database in the networked system is extracted. The subset of data is indexed to generate an index. Using the index, a preview of the subset of data may be provided to users in response to a user request without accessing the database.

  • Patent number: 9161425
    Abstract: 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.
