20140267104 | OPTIMIZED ADAPTIVE THRESHOLDING FOR TOUCH SENSING - Methods, systems, computer-readable media, and apparatuses for recognizing touch input for a touch panel are presented. In some embodiments, a method for recognizing touch input for a touch panel includes scanning the touch panel over a first frame including at least one touch panel blob resulting from a touch on the touch panel. The method also includes scanning the touch panel over a second frame including at least one touch panel blob resulting from a touch on the touch panel. The method additionally includes processing the touch panel blob within the first frame based at least in part on a first touch-reporting sensitivity and processing the touch panel blob within the second frame based at least in part on a second touch-reporting sensitivity. The method further includes determining whether a valid touch exists based at least in part on the processing step. | 09-18-2014 |
20140306903 | METHODS OF EVALUATING TOUCH PROCESING - A touchscreen system includes a touchscreen configured to receive touch data from a user, a plurality of modules, and a touch performance profiler module communicatively coupled to at least one of the plurality of modules. The plurality of modules are collectively configured to process the touch data and display an output based on the processed touch data. The touch performance profiler module is configured to monitor the at least one of the plurality of modules in real-time and output performance attributes of the at least one of the plurality of modules based at least in part on the monitoring. | 10-16-2014 |
20140306910 | ID TRACKING OF GESTURE TOUCH GEOMETRY - Systems, apparatus and methods for touch detection are presented. Multiple fingers (two to five) from one hand are tracked based on fast moving fingers being group in a fixed position relative to one another. Touch points are matched from a first time to a second time wherein the matching minimizes relative movement between the tracked fingers. In some embodiments, a touch sensor receives first and second touch data comprising touch detections. A processor matches, for several candidate matches, touch detections from a first set to a second set. For each match, the processor further computes a rotation and translation matrix between the first set and the second set; applies the rotation and translation matrix to the first set to determine a result; and calculate a Euclidian distance between the result and the second set. Finally, the processor selects a match, from the several matches, having a minimum Euclidian distance. | 10-16-2014 |
20150062020 | SYSTEM AND METHOD FOR IMPROVED PROCESSING OF TOUCH SENSOR DATA - Implementations disclosed herein provide systems and methods for improved processing of touch sensor data with improved scalability and reduced standby power. Touch-related algorithms may be partitioned between the touch screen controller and the application processor or host such that the system can function with low standby power and low interface bandwidth while providing a scalable solution for enhanced user experience. In some aspects, a small digital processing engine and memory remains in the analog front end (AFE) of the touch screen controller to perform imagine forming algorithms that are mostly related to noise reduction and filtering schemes. | 03-05-2015 |

20140238197 | SIMULTANEOUS MULTI-MODE GAS ACTIVATION DEGASSING DEVICE FOR CASTING ULTRACLEAN HIGH-PURITY METALS AND ALLOYS - An “in-line” device to continuously remove dissolved gasses from liquid metal is described. The device described herein may contain an apparatus to create a partial vacuum, one or more ultrasonic vibrators below the surface of the liquid metal to evolve gas bubbles within the metal, and a high-frequency vibrating metal plate which the fluid must pass over at a low depth. The device may be used to create high quality metals, including aluminum and aluminum alloy for a number of demanding applications such as pharmaceutical, semiconductor, foil, and aerospace applications including Aluminum-Lithium alloys. | 08-28-2014 |
20150078959 | PROCESS AND APPARATUS FOR MINIMIZING THE POTENTIAL FOR EXPLOSIONS IN THE DIRECT CHILL CASTING OF ALUMINUM LITHIUM ALLOYS - Steam exhaust ports are located around a perimeter of a direct chill casting pit, at various locations from below the top of the pit to the pit bottom to rapidly remove steam from the casting pit with addition of dry excess air. Gas introduction ports are also located around a perimeter of the casting pit and configured to introduce an inert gas into the casting pit interior. | 03-19-2015 |
20150132180 | PROCESS AND APPARATUS FOR DIRECT CHILL CASTING - A process in direct chill casting wherein molten metal is introduced into a casting mold and cooled by impingement of a liquid coolant on solidifying metal in a casting pit including a movable platen and an occurrence of a bleed-out or run-out is detected the process including exhausting generated gas from the casting pit; and introducing an inert gas into the casting pit, the inert gas having a density less than a density of air; reducing any flow of the liquid coolant. | 05-14-2015 |
20150139852 | PROCESS AND APPARATUS FOR DIRECT CHILL CASTING - A system comprising at least one furnace including a melt containing vessel; an intermediate casting product station coupled to the at least one furnace and operable to receive a molten metal from the at least one furnace, the intermediate casting product station including a casting pit, at least one moveable platen disposed in the casting pit, an array of exhaust ports about at least a top periphery of the casting pit, and an array of gas introduction ports about at least the top periphery of the casting pit; and an inert gas source operable to supply an inert gas to the array of gas introduction ports. | 05-21-2015 |
