    Abstract: An LED strip featuring perforations between adjacent LEDs that enable one to break the LED strip at the perforation using mere hand pressure. In another aspect of the invention, not only does the LED strip feature “polarity-correcting” circuitry, but also that each LED proper contains such a polarity-correcting circuit, so that regardless of where the lighting strip is broken, the broken-off portion still features polarity-correcting qualities. In yet another aspect of the invention, the LED strip can be broken at any perforation, and the two broken surfaces will each feature electrical contacts or connectors that can be removably (temporarily) attached to a pair of electrical conductors (e.g., wires), thereby permitting each of the remaining and broken-off sections of the original LED strip to function as a light source, as well as to be able to connect to both “upstream” electrical sources and “downstream” electrical loads such as additional LED strips.

  • Patent number: 8648541
    Abstract: Systems, apparatuses, and methods are provided that include alterable characteristics and such alterable characteristics may be coordinated. Such systems, apparatuses, and methods may include wearable apparatuses and such alterable characteristics may relate to illumination conditions. In one example, a wearable apparatus includes an illumination device that may be manually manipulated between two different illumination conditions. In another example, two wearable apparatuses may each include an illumination device and operation of the two illumination devices may be coordinated. In a further example, operation of an apparatus may be controlled by a third party or venue. Still another exemplary system may include a capturing device for capturing a characteristic of an object and controlling an output device of an apparatus to operate with the same characteristic as the captured characteristic.

  • Patent number: 8602592
    Abstract: Projection apparatus for projecting a radiation spot on a working plane includes a plurality of stacks of diode-laser bars. Each stack provides a beam of laser radiation. The diode-laser bars in each stack are arranged one above another in the fast-axis direction of the diode-laser bars. A corresponding plurality of beam-expanders expands the beam from the corresponding diode-laser bar stack in the slow-axis direction of the diode laser bars only. A focusing lens collects the slow-axis expanded beams and projects the slow-axis expanded beams into the working plane to form the radiation spot.
