Title: Method and apparatus for real time compression and decompression of a digital motion video signal
Inventor: KEITH MICHAEL
IPC: H04N19/94
Filed: 1993-03-19
Abstract: A bitstream (100) representative of at least one digital video image is decoded in real time by providing a code-book index from the bitstream (110), applying the code-book index to an index table to determine an index value (120), and comparing the index value to a first predetermined threshold (130). If the index value is greater than the predetermined threshold, then at least one current pixel is determined by copying a corresponding previous pixel into the location of at least one current pixel (140); otherwise the index value is applied to a vector table to determine at least one vector value (150) and a current pixel is determined from the vector value and a corresponding previous pixel (160). A  digital video image is encoded in real time by selecting at least one pixel for encoding and determining at least one difference value between the selected pixel and at least one corresponding previous pixel (344). An index value corresponding to the location in a first table of the difference value is calculated (346). If the index value is equal to a first predetermined value then a run-length counter is incremented by a second predetermined value and the process is repeated until the index value is not equal to the first predetermined value. The run-length counter is then encoded. If the index value is not equal to the first predetermined value then the index value is encoded.

Title: Use of genetic markers to diagnose familial dysautonomia
Inventor: BLUMENFELD ANAT
IPC: C12Q1/68
Filed: 1993-05-25
Abstract: Familial dysautonomia (FD), the Riley-Day syndrome, is an autosomal recessive disorder characterized by developmental loss of neurons from the sensory and autonomic nervous system. It is limited to the Ashkenazi Jewish population, where the carrier frequency is 1 in 30. We have mapped the FD gene to the chromosome region 9q31-q33 by linkage with ten DNA markers in twenty-six families. The maximum lod score of 21.1 with no recombinants was achieved with D9S58. This marker also showed strong linkage disequilibrium with FD, with one allele present on 73 % of all affected chromosomes compared, to 5.4 % of control chromosomes (X2 = 3142, 15 d.f. p < 0.0001). The other nine markers, distributed within 23 cM proximal or distal to D9S58, also yielded significant linkage to FD. D9S53 and D9S105 represent the closest flanking markers for the disease gene. This localization will permit prenatal diagnosis of FD in affected families.

L'extrémité d'échappement que l'on propose, possède une double fermeture qui empêche l'air extérieur d'entrer à l'intérieur du bâtiment et emprisonne une certaine quantité d'air dans un cylindre rotatif situé entre les deux fermetures, agissant ainsi comme isolant thermique entre l'entrée et la sortie de l'extrémité d'échappement lorsqu'elle est en position fermée. Le cylindre possède une plaque agissant à la manière d'un clapet et d'un contrepoids et deux ouvertures rectangulaires dont l'une d'elle située sous le clapet. Le clapet est actionné par le flux d'échappement qui est dévié vers le haut par la conduite d'entrée et poussé faisant ainsi pivoter le cylindre. Le clapet étant poussé vers le haut, le flux d'échappement passe par l'ouverture situé sous le clapet, entre à l'intérieur du cylindre et sort par la seconde ouverture du cylindre ouverte elle aussi lors de la rotation du cylindre. Le flux d'échappement poursuit ensuite son chemin par la conduite de sortie dirigée vers le bas, protégant ainsi le système des intempéries (pluie ou neige ) tout en laissant le flux s'échapper vers l'extérieur du bâtiment.
