  • Patent number: 10378702
    Abstract: A portable light may comprise: a light body having an illumination, e.g., white, light source and a laser light source supported thereby, each source being selectively energizable for producing light; and a switch for selectively energizing the illumination light source and/or laser light source. The laser light source is configured to provide a plane of laser light, so as to create a line of laser light on objects illuminated by the plane of laser light. The laser light source may include a cylindrical lens to create the plane of laser light. The plane of laser light may be rotatable relative to the light body. A TIR optical element may also be disposed in front of the illumination light source for receiving the light produced thereby.

  • Patent number: 10326292
    Abstract: A method for charging a battery may comprise: setting an initial low charge current level; repetitively interrupting charging in a periodic cycle, and: measuring an open circuit battery voltage when charging is interrupted, determining from the open circuit battery voltage a corresponding predetermined charging current; applying the predetermined charging current; and repeating the periodic cycle. A method may also comprise: setting an initial charge current level, measuring the supply voltage, and decreasing the charge current level if the measured supply voltage is less than a predetermined voltage.

  • Publication number: 20190003658
    Abstract: A portable light may comprise: a light body having an illumination, e.g., white, light source and one or more laser light sources, each light source being selectively energizable for producing light; and a switch for selectively energizing the illumination light source and/or the laser light sources. The one or more laser light sources provide diverging narrow beams of laser light, so as to appear as spaced apart dots or spots of laser light on objects illuminated by the beams of laser light. Because the laser light beams diverge, the distance between the dots is proportional to the distance to the object which the dots illuminate. A TIR optical element may also be disposed in front of the illumination light source for receiving the light produced thereby.
