International Classification:

G08G 1095

US Classification:

340907, 34081545, 34081565

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.

11/382017

Inventors:

O. David Sparkman - Antioch CA, US
Steven M. Colby - Palo Alto CA, US

International Classification:

G01N 27/62

US Classification:

324464

Abstract:

Systems and methods of generating ions at atmospheric pressure are presented. These systems and methods include spatially dependent analysis of a sample using an effusive ionization source. Systems and methods of isolating samples at atmospheric pressure are presented. These systems and methods include using a barrier to prevent metastables or electrons from an effusive ion source from reaching a sample unless the sample is in an analysis position. Systems and methods of using metastables in collisionally induced dissociation are presented.

Appl. No.:

10/859734

Inventors:

Steven M. Colby - Palo Alto CA, US

International Classification:

G06F 17/00

US Classification:

715257, 715255, 715258, 715200, 715256

Abstract:

Systems and methods of correcting grammatical and spelling errors that involve improper positioning of a whitespace character and/or an extra whitespace character. Removal of an extra whitespace character or repositioning of an improperly positioned whitespace character may result in correction of two misspelled words in a single correction step.

Abstract:

Systems and methods for providing customization in asymmetric communication are disclosed. An excess of information is broadcast from a transmitter to multiple receivers in what is optionally a one-way transmission. The excess of information includes metadata used to select which subset of the excess of information is presented to a user and which subset of the excess of information is discarded. The metadata includes criteria that are compared with various, possibly different, customization factors stored on each of the multiple receivers. This comparison is used to determine which subsets of the excess information are presented and which are discarded. Because the customization factors can be different on different receivers, customization of the presented information is achieved. The customization factors optionally include geographic information resulting in customization based on a receiver location. The excess information optionally includes radio or television signals.
