  • Emergency lighting device
    Patent number: 9107269
    Abstract: An emergency lighting device includes a backup power supply for illuminating a light during a power loss. The lighting device includes a transmitter, which transmits a signal to a receiver during a power outage. When the receiver receives the signal, the source of power switches from the primary power source, e.g., AC utility power, to a backup power source, e.g., DC battery power. The lighting device may include an LED lamp in which AC-LEDs are selectively illuminated when primary power source is delivered and DC-LEDs which are selectively illuminated during a power outage.

  • Mapping system and method for determining optimal radio transponder placement
    Patent number: 7541925
    Abstract: A mapping system and method. The mapping system comprises an electromagnetic field generator, a layer of electromagnetic field absorbing material over an object, and an infrared camera. The electromagnetic field generator is adapted to generate an electromagnetic field and expose the electromagnetic field absorbing material and object to the electromagnetic field. The layer of electromagnetic field absorbing material is adapted to absorb the electromagnetic field and generate areas of thermal differences within the electromagnetic field absorbing material. The infrared camera is adapted to detect the areas of thermal differences.
