| 20120098672 | ARC Fault Detection Method and Apparatus - Load current from an electrical AC supply circuit is monitored so that both high frequency (10-100 kHz), and low frequency (60 Hz) signal current components are measured over certain time periods. A high frequency energy component is measured in an integral fashion, e.g., summing a plurality of samples taken. A certain amount of high frequency energy during a half-cycle is required to indicate an arc event. A certain number of these arc events per half-cycle must occur within a specific time period to indicate the presence of an arc. The root-mean-square (RMS) value of the low frequency energy component is used to determine the severity of the arc. The higher the amperage of the load current arc, the faster the arc fault circuit interrupter (AFCI) will respond by disconnecting the arcing load from the AC supply circuit, e.g., fewer number of arc events necessary for tripping of the AFCI. | 04-26-2012 |

| 20080253133 | Reflectors for luminaires - Reflectors for luminaires that are operative to reflect light provided by a lamp are described. The reflectors have a first side operative to reflect light and a second side operative to reflect light. The first side and the second side each include a number of steps. The first side and the second side form a substantially parabolic shape. The first side may be coupled to the second side via a flat portion that is configured to couple the reflector to a luminaire housing. The steps may comprise first steps and a second step, where the first step is coupled to the flat portion, and the second step is coupled to the first step. The second step may include a plurality of steps. | 10-16-2008 |
