Abstract: A method and apparatus for suppressing fires in residential attics and basements. The components of one embodiment function in an integrated way so as to suppress residential attic and basement fires more safely and successfully than do traditional methods of the art of residential firefighting. Electronic messages from fire detection devices in residential attics and basements are processed so that a plurality of actions are performed in order to efficiently suppress fire in those residence spaces, thereby minimizing loss of human life and property. Actions include and are not limited to activation of emergency lighting in affected spaces, activation of surveillance camera devices to enable remote visual monitoring by responders, electronic notification of responders as to the existence and location of fire within the residence, alarm notification of occupants of the residence, and deployment of condensed aerosol agents to suppress or extinguish the residential attic or basement fire.

Abstract: A method for using light to indicate locations of inconsistencies on a composite structure. The method generally includes electronically accessing positional data defining one or more inconsistency locations on a composite structure. The positional data may be extracted from a part fabrication file containing numerical control (NC) data that may be used by a material placement machine to fabricate the composite structure. A light source directs light at the composite structure to illuminate the inconsistency locations as defined by the positional data. The information needed by the light source may be stored in a lookup table accessed by a processor of a vision detection system. The light allows the inconsistency locations to be noted for later action.

Abstract: A power tool movement monitor system including a first accelerometer operatively configured to sense movement along a first axis of a power tool and a first high pass filter operatively connected to the output of the first accelerometer. The first high pass filter has an output and a cutoff frequency corresponding to a predetermined acceleration limit capable of being output by the first accelerometer. The power tool movement system further includes a logic circuit operatively configured to generate a warning signal when the first high pass filter outputs a signal having a frequency equaling or exceeding the cutoff frequency of the first high pass filter.

Abstract: A method of detecting a non-fixed object in a system (12) includes applying a light emitting or generating substance to multiple objects. The objects are illuminated with an object illuminator (13). At least one of the objects (10) is determined to be a nonmember within a known pattern of objects and is identified to be a non-fixed object in response to illumination of the objects.
