Abstract: The disclosure is directed at a configurable light emitting diode (LED) driver/dimmer for controlling a set of light fixture loads comprising: a power circuit; a primary digital controller for controlling the power circuit; a set of output current drivers, each of the set of output current drivers connected to one of the set of light fixture loads for controlling the associated light fixture load; a secondary digital controller for controlling the set of output current drivers; wherein the secondary controller transmits LED control information to control outputs of the set of output current drivers; and wherein the secondary digital controller provides digital feedback control information to the primary digital controller.

Abstract: A self-provisioning antenna (SPA) system and method provides for automatic simultaneous remote optimization of one or more field antenna terminals over a wireless network. A central server communicates with a field controller to modify configurations of any directional radiating elements, filters settings, and low noise amplifier settings associated with one or more remotely located antenna banks, determines the optimal configurations based on readings of field signal quality metrics including RSSI, EC/IO, and date rate standard samples, and allows a human operator to select a configuration.

Abstract: A bootstrap assist circuit and a startup circuit comprising a voltage controlled switch and a startup ramp voltage generator connected to the voltage controlled switch that will control a high side switch, a dimming interface or an enable/disable input function. Said system is used to provide a bootstrap technique to continuously switch a floating high side switch (MOSFET) by continuously charging a capacitor and then “level shifting” said capacitor voltage across the gate and source of the said high side switch to turn the switch on.

Abstract: A particulate respirator facepiece has photocatalyst in the airflow path and a light source that illuminates the photocatalyst. Photocatalyst may include titanium oxide, tin oxide and other semiconductor photocatalysts. Strong oxidizers generated by the illuminated photocatalyst kill infectious agents and decompose toxic organic compounds. The particulate respirator facepiece can be used outdoors, illuminated by natural sunlight; indoors, illuminated by ambient lighting, and; in the dark, with the built-in light source. Light emitting diodes (LEDs) or another source of light built in to the particulate respirator facepiece illuminates the photocatalyst. Light conductors may be incorporated to distribute light from the built-in light source over the photocatalyst.

Abstract: An optical temperature compensated material level-interface sensing and control system which comprises an insertion probe (10), control circuitry and a housing enclosure (72). The probe (10) makes use of a pair of emitters and detectors, in which one pair is positioned across a channel (26) through which material passes and the other pair are mounted in a sealed tubular bracket. The first emitter and detector pair are optically active with respect to sensed material, and the other pair is optically isolated, but thermally active. The resulting signal is a function of the material's linear coefficient of absorption with the thermal influence being effectively canceled out. The outputs of the control circuit are user selectable and changeable. The device is able to detect material presence and identity for use in interface-level control applications through a wide range of pressures and temperatures in industrial applications.
