20130264247 | PROCESS OF REDUCING VISCOSITY OF HEAVY CRUDE OIL BY REMOVAL OF ASPHALTENE USING A PRECIPITATING AGENT - A process and system for reducing the viscosity of heavy and extra heavy crude oils, and more particularly to a process for reducing the viscosity of heavy and extra heavy crude oils by means of total or partial oil deasphalting using a precipitating agent in order to obtain an upgraded crude oil of lower viscosity that can be pumped without the use of diluents. The upgrading also includes a reduction in metals and sulfur associated with asphaltene removal. The process consists of relatively simple equipment such as static mixers and stirred tanks and operation temperature is low and pressure is moderate. | 10-10-2013 |

20090024756 | MEDIA CONVERTER AND A SYSTEM FOR MUTUALLY CONVERTING A PACKET-BASED DATA STREAM INTO A SERIAL DATA STREAM - A media converter, a system and a method for converting packet based data into serial data and vice versa are provided. The media converter comprises a first interface configured to receive and provide a first type of data stream based on data packets, a second interface configured to receive and provide a second type of data stream based on a continuous serial bit stream, and a signal processor connected to the first and second interfaces and configured to convert said first type of data stream into said second type of data stream and vice versa on the basis of a block encoding/decoding algorithm and a line encoding/decoding algorithm. Thus, enhanced bit error rate may be obtained, thereby allowing the use of optical transmission channels of increased length. | 01-22-2009 |

20100249496 | MEDICAL DEVICE FOR EXPLORING AND OPERATING ON THE ABDOMINAL CAVITY AND THE PELVIC CAVITY - The invention relates to a medical device including a trocar with a hollow tip for the passage of a camera, a light source and a miniature camera at the tip thereof, which transmits images to an LCD screen. The invention also includes two or more working channels on the sides thereof, for the introduction of surgical equipment for the removal of the appendix or other similarly sized structures. The camera is connected to a cable which is, in turn, connected to an LCD screen, such that the surgeon has the impression of looking at the patient's abdominal cavity through a window. | 09-30-2010 |
