20110172092 | Biochar Production Method and Composition Therefrom - The invention is directed to a method for producing an oxygenated biochar material possessing a cation-exchanging property, wherein a biochar source is reacted with one or more oxygenating compounds in such a manner that the biochar source homogeneously acquires oxygen-containing cation-exchanging groups in an incomplete combustion process. The invention is also directed to oxygenated biochar compositions and soil formulations containing the oxygenated biochar material. | 07-14-2011 |

20120007511 | AMBIENT AND TASK LEVEL LOAD CONTROL - Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for cooperatively controlling ambient level lighting in a controlled area, and task level lighting for task areas in the controlled area, wherein each task area is a separate sub-area of the controlled area. | 01-12-2012 |
20120112654 | Wireless Adaptation of Lighting Power Supply - Methods, systems, and apparatus, for wirelessly controlling a power supply device that controls a load. A wireless adapter includes a wireless communication device that receives transmissions from a wireless controller, a serial interface for a serial data connection to a power supply processing device integrated in the power supply device, an adapter processing device that receives the control signals the wireless communication device outputs, generates the control commands from the control signals, and outputs the control commands to the serial interface to cause the power supply processing device to control power provided to the load in a manner specified by the control commands, and an adapter power circuit that receives regulated direct current (DC) power from the power supply device and is powered from the regulated DC power received, and provides power to the wireless communication device and the adapter processing device. | 05-10-2012 |
20130200809 | Integrated Ambient and Task Lighting Control - Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for cooperatively controlling ambient level lighting in a controlled area, and task-level lighting for task areas in the controlled area, where each task area is a separate sub-area of the controlled area. | 08-08-2013 |

20130248693 | APPARATUS FOR DETECTING PARTICLES - A particle detection system is provided, including a sensing chamber having an inlet nozzle, an outlet nozzle, and an interrogation zone defined therebetween. Particles in a sampled environmental gas are prevented from escaping the interrogation zone by pressurizing the sensing chamber such that the pressure therein is higher than that in the outlet nozzle. This is accomplished by providing a source of extra gas to the sensing chamber, for example, by diverting gas from an inlet flow path directly to the sensing chamber. | 09-26-2013 |
