Abstract: Systems and methods of controlling traffic including a traffic signal. The traffic signal including one or more lamps configured to each display a plurality of patterns by selectively powering different groups of bulbs. Embodiments of the invention include lamps configured to alternatively display an arrow pattern, a filled circle pattern, a bar pattern or other pattern meaningful to traffic control. The pattern displayed is optionally dependant on available power sources, ambient light, traffic flow, time of day or day of week.

Abstract: A digital camera and image processing system configured for transferring image data. Transferring means including wireless transmission, transmission through a telephone network, and copying image data to detachable memory modules. Recorded images are optionally previewed and selected for transmission prior to actual transmission. Wireless transmission may be through a cellular telephone network and may be to an internet-based image processing system configured to process digital images and optionally delivery them to a client. The digital camera optionally receives data from an internet based image processing system and/or from other digital cameras. In addition to image data transmission optionally includes processing preference data, user identifying data, and address data.

Abstract: An apparatus and method for minimizing ion peak width measurements in a time-of-flight mass spectrometer to thereby minimize the effects of initial ion position distributions and initial ion velocity distributions on the mass resolution of the spectrometer are provided. Where the ion source and ion generation geometries indicate a functional relationship between the initial ion position and initial ion velocity, this relationship is substituted into the time-of-flight equation and the instrument parameters are thereafter optimized to achieve minimization of ion peak width broadening. Experimental results using MALDI indicate reductions in ion peak widths of up to 96% over those observed with traditional MALDI techniques.
