Abstract: The present invention provides a flashlight or device having a body with a battery, and a circuit therebetween; recharging terminals for recharging the battery and an adaptor having electrical connectors for connecting to a power supply; structural connection means on the body and or the adaptor to releasably connect the body and the adaptor; and electrical connection means on both the body and the adaptor to releasably electrically connect the terminals and the adaptor. The present invention also provides a flashlight having a body with a light means at one end, a battery, and a circuit therebetween, so that when the circuit is closed the light means will generate light; the light means including a conical reflector, a white light LED emitting a conical light output and a double convex lens portion, the double convex lens portion being located away from the LED so that the outside diameter of the double convex lens portion will a circle of light from the LED which is of substantially the same diameter.

Abstract: A lighting device (30) having a housing (12) which includes a lamp means, a battery housing to receive at least one battery and a switch means to open and close a circuit between said lamp means and terminals of said at least one battery when located in said housing. Said lighting device includes a lanyard (110, 112) attached to said housing (12) characterised by said lanyard having a proximal end attached to said housing (12) and a distal end, whereby said distal end or a portion of said lanyard (110, 112) is adapted to be releasably attached to said housing (12).

Abstract: A portable battery powered appliance accepts at least first and second batteries. The appliance also includes a load. a first circuit. and a second circuit. The first circuit receives power from the first battery and provides a first power. The second circuit receives power from the second battery and provides a second power. The load receives at least one of the first power and the second power.

Abstract: An intrinsically safe flashlight (100) includes a housing (100), a battery receiving region (108), an active electrical circuit (202), and a light source (118). The active electrical circuit (202) uses energy from batteries (110) received in the batter receiving region (110) of the flashlight (100) to power the light source (118). The electrical circuitry of the flashlight (110) is energy limited so that the flashlight is intrinsically safe for use in hazardous locations.

Abstract: An apparatus includes electrical contacts coupled to a LED. The apparatus further includes a positive temperature coefficient resistor in operative thermal communication and electrically in series with the LED. A resistance of the PTC resistor varies as a function of a temperature of the LED.

Abstract: A lighting device has a light source, a light pipe, two convex magnifying lenses, and an adjusting mechanism for moving the two magnifying lenses relative to the light source. The light emitted from the light source is dispersed and directed into the light pipe by a reflector. The light pipe transfers collimated light through the first and second magnifier lenses which redirects the light to produce a circular spotlight beam having uniform intensity. The size of the spotlight beam is adjusted by an adjusting mechanism.

Abstract: An apparatus includes a housing having a first wall and a sliding tray having a second wall that is generally parallel to the first wall. The sliding tray slides between a retracted position and an extended position in which the first and second walls define a battery receiving region in the sliding tray. The apparatus further includes a first battery contact provided in the first wall and a second battery contact proximate to the second wall. The first and second battery contacts electrically communicate with battery charging circuitry, and the second battery contact slides relative to the second wall in a direction that changes a battery receiving distance between the first and second battery contacts.

Abstract: A physical battery charger (104) connects to a computer (102) using a communications link such as a universal serial bus (USB) connection. Application software (114) resident on the computer (102) presents a virtual battery charger (116) on a display (110) associated with the computer (102). The virtual charger (116) provides information regarding the status of the physical charger (104) and allows the user to control the operation of or otherwise interact with the physical charger (104). The physical charger (104) also adjusts the charging rate of batteries (222) being charged based on the available power.
