Abstract: A light comprises: a light body and a laser light source supported by the light body; and a laser light source adjustment arrangement having two adjusting screws at an acute angle to each other. The two adjusting screws bear against the laser light source for adjusting, e.g., the azimuth and elevation of the laser light produced thereby. Alternatively and/or additionally, a tail cap assembly may include a housing shell defining one or more cantilevered supports and a resilient material sealing the housing shell while leaving the actuators flexibly cantilevered. Alternatively and/or additionally, the light may include a mode selecting face cap that is rotatable on the light body for selecting operating modes, including OFF.

Abstract: A light comprises: a mode selecting face cap that is rotatable on the light body for selecting operating modes, including OFF. Complementary electrical contacts on the light body and face cap enable operating modes including, e.g., ON and an optional detent retains the face cap in a rotational position for the OFF mode. Alternatively and/or additionally, the light may include a tail cap assembly including a housing shell defining one or more cantilevered supports and a resilient material for sealing the housing shell while leaving the actuators flexibly cantilevered and/or a laser light source having two adjusting screws at an acute angle to each other.

Abstract: A light comprises: a light body and a light source supported by the light body; and a tail cap assembly including one or more actuators configured for actuating one or more electrical switch contacts internal to the light body for energizing the light source. The tail cap assembly may include a housing shell defining one or more cantilevered supports extending from the housing shell with the one or more actuators at respective ends thereof. The tail cap assembly may further include a resilient material for sealing the housing shell while leaving the actuators flexibly cantilevered. Alternatively and/or additionally, the light may include a mode selecting face cap that is rotatable on the light body for selecting operating modes, including OFF, and or a laser light source having two adjusting screws at an acute angle to each other.

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.

Abstract: A lighting circuit includes a controllable electronic device in series with a power terminal of a controller, wherein operation of a switch causes the controller to maintain the electronic device conductive, whereby the controller then remains powered; and wherein the controller responds to a subsequent operation of the switch to render the electronic device nonconductive, whereby the controller is then unpowered even when electrical power is received. The lighting circuit is suitable for use, e.g., in a portable or other battery powered light.

Abstract: A battery charger comprises: a housing having at least one cradle; a connector port for receiving at different times electrical plug connectors having different contact configurations; electrical receptacles in the connector port for receiving at different times electrical plug connectors associated with different electrical power supplies, plural electrical receptacles having different contact configurations; the plural electrical receptacles being closely adjacent such that an electrical connector inserted into one electrical receptacle physically prevents an electrical connector from being inserted into the other electrical receptacle; and an electrical circuit coupling electrical power received at the electrical receptacles to the at least one cradle.

Abstract: A connector comprises: an elongated connector body defining a longitudinal direction with an electrical connector frame at one end thereof; the elongated connector body having a longitudinal alignment feature on the elongated connector body configured for aligning the elongated connector body, a guide feature defining a unique orientation thereof, and a retaining feature configured for retaining the elongated connector body in a connector guide.

Abstract: A light for mounting on an implement is provided. In particular, a light configured to be releasably attached to a firearm is provided. The light includes first and second light elements. A selector switch is operable to select which of the two light elements is energized when a primary switch is actuated.
