Patent number: 10568846Abstract: Compositions are described that include a betacryptoxanthin extract, rich in trans-betacryptoxanthin, which are prepared by a cost and time effective process and are for use in methods of enhancing cardio-respiratory fitness for physical performance and exercise endurance and to maintain healthy lung function. Betacryptoxanthin extract is prepared by a cost and time effective process of saponification and column chromatography, in which saponification cycle time, solvent amount, column separation time and silica amount are reduced, thus making it industrially viable. Betacryptoxanthin compositions increase exercise time, endurance performance, and lung capacity and maintain healthy lung and cardiovascular function during such physical activities. The compositions also improve physical performance, attenuate muscle fatigue, and enhance aerobic respiration utilization capacity.Type: GrantFiled: April 27, 2016Date of Patent: February 25, 2020Assignee: OmniActive Health Technologies LimitedInventors: Jayant Deshpande, Abhijit Bhattacharya, Vijaya Juturu, Khadija Ghanam, Vandita Srivastava, Vallabh Mulay

Patent number: 9361822Abstract: The present disclosure relates generally to systems and techniques for applying color adjustments to a display. In certain embodiments, the color adjustment techniques may be employed to transition current color correction values, which are based on a previously detected temperature of the display, to target correction values, which are based on a presently detected temperature of the display. Adjustment increments for each color channel of the display may be determined based on the color channel that has the largest difference between the current color correction value and the target color correction value. In particular, the number of adjustment steps may be determined so that the adjustment increment for each channel is less than or equal to a maximum adjustment increment.Type: GrantFiled: November 9, 2011Date of Patent: June 7, 2016Assignee: APPLE INC.Inventors: Kelsey Yukio Ho, Abhijit Bhattacharya, Christopher William Baldwin, Gabriel Gheorghe Marcu, Jesse Michael Devine

Patent number: 6324353Abstract: In a multifunctional printing method and printing system, printed material is checked, verified and tracked. For that purpose different test equipments are located in-line with a printing line. Magnetic information being printed by a printing station onto the recording carrier using magnetic ink character readable toner may be in-line tested by a magnetic test equipment, which reads information from the magnetic recording zone on the carrier. Optical information may be tested by an in-line mounted optical test equipment, respectively. Further in-line test equipment is proposed such as a laser bar code scanner and an address reader. The printing line may have additional devices such as print preprocessing unwinders or print postprocessing stackers, folders or cutters.Type: GrantFiled: August 29, 2000Date of Patent: November 27, 2001Assignee: OcéPrinting Systems GmbHInventors: Thomas Laussermair, Abhijit Bhattacharya, Michael Schmitt, Tony Ribeiro, Frank Lorenz, Leon T.
