Title: Burst and packet wireless transmission using product codes with iterative decoding
Inventor: BERGER HARVEY L
IPC: H04L12/56
Filed: 2001-01-10
Abstract: A communication subsystem (300) for transmitting error correction coded data in packets (200) includes an input buffer (302) storing unencoded data, a product coder (304) coupled to the input buffer, and a time division transmitter (306). The product coder (304) outputs product coded data packets (200) having a packet size, and the time division transmitter (306) transmits the product coded data packets (200) in a data section (109) of a frame (104). The data section (109) has a length substantially equal to an integer multiple of the packet size. The communication subsystem (300) may use a (s, t) x (n, m) product code specifically adapted to product code 53 byte ATM cells. A method for communicating error correction coded data in packets includes storing unencoded data in an input buffer (402), product coding the unencoded data (404), and outputting product coded data packets (406) having a packet size. The method also includes time division transmitting (408) the coded data packets in a data section (109) of a frame (104) where the data section length is substantially equal to an integer multiple of the packet size.

Title: Device and method for non-invasively measuring and determining moisture content and density of loose and packaged tobacco
Inventor: KHAZANSKI MICHAEL
IPC: G01N22/00
Filed: 1999-07-30
Abstract: A method and a device which can be used to measure the moisture content and the internal structure of material on a tobacco bale (12), or of a bulk volume of material such as loose tobacco leaves (14), by using microwave radiation. A  microwave radiation source (28) is located on one side of the tobacco, such as the tobacco bale, and an antenna (30) is located on the opposite side of the bale. The radiation source beam (32) is transmitted through a portion of the bale and is received by the receiving antenna (36), which then produces a signal (38). This signal is used to determine the moisture content of that portion of the bale and the mass uniformity of the bale. In addition, the methods and devices described herein can also be used to measure the moisture content of a bulk volume of loose tobacco leaves, for example as these leaves travel through a silo. Also, in a method for analyzing the internal structure of packaged tobacco, the internal structure is analyzed to detect the presence of any foreign objects or matter in packaged tobacco, as well as to confirm the presence of tobacco material throughout the package. The structural data is collected from the received and/or reflected microwaves, which are also analyzed to determine the moisture content. The raw structural data are then analyzed with detection, classification, and/or decision algorithms for analysis of the raw data. Preferably, the data analysis is based on pairs of attenuations (42) and phase shifts (44) obtained by passing, microwaves at a plurality of frequencies through the package of tobacco which features foreign matter or objects, collectively termed "foreign components" and/or non-uniformities. This unique method enables achievement of high levels of accuracy and precision in detection and classification of the sample, in general, and of the foreign components and/or non-uniformities, in particular.

Si tel est le cas, on peut prédire que les protéines contenant ces sites fonctionnels présentent les fonctions biologiques correspondantes. Dans des modes de réalisation préférés, on utilise une bibliothèque de descripteurs de sites fonctionnels afin de vérifier les structures imprécises de protéines, dérivées par des méthodes informatiques d'informations sur les séquences d'acides aminés, pour prédire les fonctions biologiques de ces séquences et des gènes codant pour elles.

Title: Optical mems switch with imaging system
Inventor: RYF ROLAND
IPC: G02B6/35
Filed: 2002-04-30
Abstract: In an all optical switch an imaging system is interposed between the micro lens array and the moveable micro mirrors of a MEMS device to which, or from which, the light beams are directed. This causes an image of the micro lens array to be formed at the MEMS device, or vice-versa, thus effectively eliminating the distance between the micro lens array and the MEMS device. The imaging system may be a telecentric system. The size of the arrangement may be reduced by compacting the optical path, e.g., using appropriate conventional mirrors, and/or employing folded arrangements, i.e., arrangements in which there is only one MEMS device stage that does double duty for both input and output through the use of at least one conventional mirror.  The overall system is arranged to account for any inversions introduced.

Title: System and method for enhanced vertical resolution magnetic resonance imaging logs
Inventor: HAGIWARA TERUHIKO
IPC: G01R33/44
Filed: 2000-10-17
Abstract: An interpretation method and system for NMR echo-train data in thinly laminated sequences. The invention uses geological information obtained at higher vertical resolution, such as using Electric Micro Imaging, to enhance  the vertical resolution of echo-train data, and thus avoids log interpretations in which the hydrocarbon potential of the formation can be misread because low resolution logs tend to provide an average description o f the formation. Such averaging is especially problematic in thinly laminated sequences that consist of highly permeable and porous sand layers and less permeable silt or essentially impermeable shale layers. In a preferred embodiment, using the additional high-resolution formation information one c an estimate the typical T2-spectra of lithological laminae, and significantly enhance the permeability estimate in the laminated sequences. In another aspect the system and method of the preferred embodiment use neural network( s) to further enhance the resolution of a particular log measurement. The metho d and system are applicable to any temporal data from other logging tools, suc h as the thermal neutron decay log and others. The system and method enable proper evaluation of the high potential of thinly laminated formations, whic h may otherwise be overlooked as lowpermeable formations.
