Publication number: 20140122375Abstract: A parking pricing with occupancy feedback control for achieving an optimal occupancy level for a parking space area, so that at least one space is available and circling is not necessary. The parking pricing with occupancy feedback control system proposes to implement a market based parking pricing from an occupancy control approach. The parking price system seeks to maintain a desired occupancy level by measuring real-time parking space occupancy and using controller to automatically adjust parking rates to change with real-time demand. Occupancy feedback control is used to adjust parking space pricing so that the occupancy level approaches a target capacity level. Parking space sensors measure the presence of the vehicles, a parking control engine compares the real-time occupancy of the parking spaces to the target occupancy of the parking spaces, and adjusts the parking pricing to regulate the demand, so that the parking space occupancy converges to its target.Type: ApplicationFiled: November 1, 2012Publication date: May 1, 2014Applicants: Palo Alto Research Center Incorporated, Xerox CorporationInventors: Faming LI, Haitham Hindi, Daniel H.

Patent number: 8708450Abstract: An indirect media flatness measurement system, and method, by which the appropriate level of hold-down force may be determined with some degree of quantitative accuracy. In an ink jet printer that is operative to subject a substrate media to a hold down force during printing, the method including printing a predetermined test image having a predetermined pattern on a substrate media using an ink jet print apparatus to produce a test print. Optionally, pattern may be an array of test symbols. The test symbol may include a line printed on the substrate media in a direction perpendicular to a process direction of the printer.
