Abstract: An LED lamp that can take the place of incandescent lamps. An elevated light source is positioned above a screw-type base. A first plurality of LEDs is connected in a series on one side of a flat substrate and a second plurality of LEDs, equal in number to the first, is connected in series on an opposite side of the substrate. Each LED of the first and second plurality of LEDs is mounted proximate a heat sink and a drive circuit is provided for the LEDs, with the drive circuit being located proximate and electrically connected to the screw base.

Abstract: Multiple films of red-green-blue (RGB) luminescent silicon nanoparticles are integrated in a cascade configuration as a top coating in an ultraviolet/blue light emitting diode (LED) to convert it to a white LED. The configuration of RGB luminescent silicon nanoparticle films harnesses the short wavelength portion of the light emitted from the UV/blue LED while transmitting efficiently the longer wavelength portion. The configuration also reduces damaging heat and/or ultraviolet effects to both the device and to humans.

Abstract: A direct driver system is disclosed for powering and regulating LED lamps. An LED driver is configured to serve as a linear regulator/switcher, thus minimizing the need for the use of switched-mode power supplies, flybacks or pulse-width modulation (PWM) in LED driver circuitry. The direct drive is configured with a voltage source, a resistive element or apparatus, and a predetermined number of LEDs optimized to produce customizable features in relation to driver efficiency, power factor and regulation. When dimming circuits are used, an active region for the LED can be defined using a phase angle of the dimming circuit.

Abstract: The system and method for providing a data update and synchronization via a wireless system disclosed herein. The system includes a mobile transceiver assembly having an LCD and a menu navigation device, and an operations center operatively coupled to the mobile transceiver assembly via the radio frequency link. The method includes receiving a database update from the mobile transceiver assembly, detecting actuation of “edit profile” request of the mobile transceiver assembly, causing a notification signal to be transmitted to the facility controller, causing an identity and the location of the mobile transceiver assembly to be transmitted to the facility controller; and enabling a synchronized response action to be initiated by an operations center database Server located at the operations facility, thus causing the update of both databases simultaneously.

Abstract: The invention disclosed herein is a dynamic dummy load to allow a phase control dimmer to be used with LED lighting. The invention includes providing a dynamic dummy load to provide a load to the dimmer when the LED electronics do not provide sufficient load due to start up issues or ringing in the circuit, the dynamic dummy load providing a reduced flow of current when the LED and its converter electronics provide sufficient current draw from the dimmer. The system generally includes a power source electrically connected to a phase control dimmer, the phase control dimmer electrically connected to converter circuitry to convert the AC power output of the dimmer to DC power output for powering the LED lighting, a dynamic dummy load electrically connected in parallel with the converter circuitry, the dummy load varying its current draw in response to operation of the converter circuitry.

Abstract: A system and method for providing emergency response via a wireless link. In a limited and localized coverage area, a plurality of mobile pendant units is provided in communication with a local node and router. The mobile pendant units each include a wireless transceiver for communication with a wireless transceiver of the local node and router. The local node and router includes an interface to traditional networks, such as wired, wireless or satellite, which permits communication between an operations center and one or more of the mobile pendant units. Once one of the mobile pendant units is activated, its location is known and verbal communication is facilitated between the mobile pendant unit, the local node and router, and an operations center, as well as between the mobile pendant units.
