Abstract: Described herein are photonic communication platforms that can overcome the memory bottleneck problem, thereby enabling scaling of memory capacity and bandwidth well beyond what is possible with conventional computing systems. Some embodiments provide photonic communication platforms that involve use of photonic modules. Each photonic module includes programmable photonic circuits for placing the module in optical communication with other modules based on the needs of a particular application. The architecture developed by the inventors relies on the use of common photomask sets (or at least one common photomask) to fabricate multiple photonic modules in a single wafer. Photonic modules in multiple wafers can be linked together into a communication platform using optical or electronic means.

Abstract: A liquid phase enhanced oil recovery system that, in a stimulation phase, pumps a liquid mixture of propane (C3) and butane (C4) having a starting ratio of C3 to C4 into a well. During a subsequent production phase, liquid C3 and liquid C4 is recovered by a stabilizer from the produced oil, and, in addition, C3 and C4 can be recovered from the produced hydrocarbon vapor and liquefied, The ratio of liquid C3 to liquid C4 can then be re-adjusted and may not be the same as the starting ratio. All of the liquid C3-C4 can be recycled back into the well in subsequent stimulation phases. The method works at relatively low pressures, so that a pump or pumps can be used for stimulation treatment. The site equipment is compact enough that it can be mounted on one or more skids to ensure transportability to be used on other wells.

Abstract: A liquid phase huff and puff method of enhanced oil recovery (EOR) applied to multiple groups of existing horizontal or vertical wells in a shale or tight rock reservoir resulting in additional oil recovery. The method utilizes a pumping phase for a chosen pumped well group, and a production phases for the remaining well groups. The production phases typically last longer than the pumping phases. The method operates such that while one of the well groups is pumping, the remaining well groups are producing, A new pumped well group is chosen from the production well groups upon completion of each pumping phase, with the previous pumped well group being converted to a producing well group.

Abstract: A liquid phase enhanced oil recovery system (EOR) that pumps a liquid mixture consisting mostly of propane (C3) and butane (C4) into a horizontal or vertical well during the stimulation treatment phase to recover additional hydrocarbons from the reservoir. During the subsequent production phase a liquid mixture is produced that includes water, hydrocarbon vapor, and hydrocarbon liquids which include oil and C3 and C4. The C3 and C4 is recovered from the hydrocarbon vapor and can be liquefied, combined with the liquid C3-C4 recovered from the produced liquid hydrocarbon stream and then all the C3-C4 can be recycled back into subsequent stimulation treatment phases. The method works at relatively low pressures so that a pump can be used for stimulation treatment. The site equipment is light enough that it can be mounted on one or more skids to ensure transportability to be used on other wells.

Abstract: A method and apparatus is provided for converting the frame rate of digital video data from one frame rate to another frame rate without introducing motion artifacts into the converted video data stream. A high frame rate video stream is converted into a lower frame rate video stream by selecting whole frames from the high frame rate video stream and outputting the selected frames as the lower frame rate video stream. To insure that only whole frames are selected from the high frame rate video stream, the frame rate of the high frame rate video stream is locked to the frame rate of the lower frame rate video stream. A frame cycle is defined to be an integer number of frames in the higher frame rate stream. The higher and lower frame rates are locked by repeatedly selecting and outputting as the lower frame rate video stream, over a time period that is substantially equal to one frame cycle, an integer number of frames from each frame cycle of the higher frame rate.
