20110309952	ACCESSIBLE PEDESTRIAN SIGNAL SYSTEM - Methods and systems are provided for conflict monitoring and error detection in accessible pedestrian signal systems. A primary conflict monitor and error detector is configured to control output of audible and vibrotactile pedestrian signal indications. The primary conflict monitor and error detector monitors the current traffic state, and verifies audio and vibrotactile control signals against the current traffic state and user settings to determine whether to enable output of audible and vibrotactile pedestrian signal indications. The primary conflict monitor and error detector may transmit information about the audio and vibrotactile control signals to a secondary conflict monitor and error detector, which verifies the information received against the current traffic state and user settings, and inhibits output of audible and vibrotactile pedestrian signal indications in the event of a detected conflict or error.	12-22-2011

20110116090	SYSTEM AND METHOD FOR REAL TIME DETERMINATION OF SIZE AND CHEMICAL COMPOSITION OF AEROSOL PARTICLES - This invention is an apparatus and method of real time determination of particle size and optionally chemical composition or both. An aerosol beam generator focuses a beam containing sample particles that passes through a sizing laser beam of approximately constant width to produce light scattering that is detected by a light detection means, allowing generation of electrical pulses that may be used to compute particle velocity. In being formed into a beam, the particles are accelerated to terminal velocities that are functions of their sizes. The duration of time elapsed while a particle passes through the width of the sizing laser beam is a function of its velocity which, in turn, is a function of its size. Chemical composition of the particle is determined by suitable analytical means included in the apparatus, such as mass spectrometry.	05-19-2011

20080246404	VEHICLE HEADLIGHT BEAM CONTROLS - A method of manually overriding automatic activation of an automatic headlight control system for a motor vehicle, headlamps operable in a high beam state and a low beam state, a high/low beam switch movable from a neutral position to a latched position and from a neutral position to a non-latched position for controlling the state of the headlamps and a headlamp on/off switch comprising a multi-position switch with at least a selectively automatic headlamp position is disclosed. The system includes forward-facing sensor for collecting light emanating from for instance a second vehicle, and a controller for controlling, when the headlamp switch is detected as being in the automatic headlamp position, the headlamp states as a function of the sensed intensity of the beam of light emanating from said second vehicle. The method comprises the steps of: monitoring the states of the headlamps when the headlamp on/off switch is in the automatic position, causing the controller to initiate an override mode if the high beam states is detected (step	10-09-2008
