20150065748 | PROCESS FOR SEPARATING ARYL CARBOXYLIC ACIDS - In the present disclosure, a process for separating aryl carboxylic acids from a mixture comprising a plurality of aryl carboxylic acids is provided, wherein the process comprising the steps of heating a first mixture that comprises at least two aryl carboxylic acids wherein each of said aryl carboxylic acids having a pre-determined liquefaction temperature and a pre-determined precipitation temperature, with at least one ionic compound, at a pre-determined temperature to obtain a liquefied composition; and cooling the liquefied composition under controlled temperature conditions to fractionally crystallize and precipitate an aryl carboxylic acid. The precipitated aryl carboxylic acid is isolated and the obtained mother liquor is subjected to iterated cooling steps until each of the remaining aryl carboxylic acids precipitates one by one. The mother liquor remains in liquefied form. | 03-05-2015 |

20110109615 | ENERGY SAVING DRIVING SEQUENCE FOR A DISPLAY - A method of writing a display image to a display having an array of pixels according to a selected driving sequence. One driving sequence includes addressing each color row in a line of the array in a sequence before addressing a second line. Another driving sequence includes addressing a first color row of each line in the array before addressing a second color row of each line in the array. | 05-12-2011 |
20140191980 | SYSTEM FOR REUSE OF TOUCH PANEL AND CONTROLLER BY A SECONDARY DISPLAY - This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for controlling a display device that includes a first display, a touch screen disposed on the first display and a second display. In one aspect, the first display may be disposed on a first side of the display device (e.g., the front side) and the second display may be disposed on a second side of the display device (e.g., the back side). The second display may consume less power than the first display. Even when the first display is switched off, a control system may be configured to control the second display in response to input received from the touch screen disposed on the first display. The control system may be further configured to control the first display in response to input received from the touch screen when the first display is switched on or when the second display is not in use. | 07-10-2014 |
20140267029 | METHOD AND SYSTEM OF ENABLING INTERACTION BETWEEN A USER AND AN ELECTRONIC DEVICE - A method and system for enabling interaction between a user and an electronic device includes sensing at least one of position and movement of at least one finger on a physical keyboard, determining position of the finger on the physical keyboard and emulating at least one of a virtual mouse, a virtual touch screen, a virtual hand on a display, and a gesture sensing technique to enable the interaction in accordance to at least one of the position and the movement of the finger. The system includes an electronic device, a communication interface, a memory and a processor. | 09-18-2014 |
