Title: Glial cell line-derived neurotrophic factor receptor
Inventor: FOX GARY M
IPC: C07K14/705
Filed: 1997-04-15
Abstract: The present invention relates to glial cell line-derived neurotrophic factor (GDNF), a potent neurotrophin that exhibits a broad spectrum of biological activities on a variety of cell types from both the central and peripheral nervous systems. The present invention involves the cloning and characterization of a high affinity receptor for GDNF. This molecule has been named GDNF receptor (GDNFR) since it is the first known component of a receptor system. Nucleic acid and amino acid sequences are described for GDNFR protein products. A hydrophobic domain with the features of a signal peptide is found at the amino terminus, while a second hydrophobic domain at the carboxy terminus is involved in the linkage of the receptor to the cell membrane. The lack of a transmembrane domain and cytoplasmic region indicates that GDNFR requires one or more accessory molecules in order to mediate transmembrane signaling. GDNFR mRNA is widely distributed in both nervous system and non-neural tissues, consistent with the similar distribution found for GDNF.

Filed: 1998-10-19
Abstract: A method and apparatus for performing high-speed computation of a Montgomery value defined as 2 2k mod(n) for an arbitrary modulus n is disclosed. After loading the value of 2(h*m)+1 into a first register and the value of the modulus n in a second register, the bits of modulus n are shifted in a most significant bit direction before a repeated modular reduction and squaring process. This allows the computation of the Montgomery value for modulus values of arbitrary sizes while reducing the number of computations required by a processor with a limited operand size.

Abstract: On décrit un procédé perfectionné de codage et de décodage, servant à déterminer l'état des extrémités d'un décodage à convolution mettant en oeuvre un algorithme de Viterbi, sans utilisation de binaires d'extrémités. Les binaires d'information de rang supérieur (12) sont d'abord codés à l'aide d'un code à blocs (14). Le mot de code à blocs (14) et le reste des binaires d'information (11) sont alors divisés en plusieurs salves (B-salve). Chaque salve est codée au moyen d'un code à convolution. La partie binaires d'information de rang supérieur du mot de code à blocs est alors placée au commencement de la salve de codage destinée au codeur à convolution et la partie binaires de parité peut être placée entre l'extrémité de la partie binaires d'information de rang supérieur et l'extrémité de la salve de codage. Dans le procédé de décodage à convolution destiné à chaque salve, l'état d'extrémités est déterminé par le mot de code à blocs détecté et valable, après combinaison des procédés de décodage à convolution de toutes les salves. Il est possible d'optimiser les performances du taux moyen d'erreur sur les binaires (BER) ainsi que le taux d'insuccès de détection, en changeant de place les binaires de parité dans chaque salve de codage de messages.

Title: Parallel rf optimization of wireless networks
Inventor: PITTAMPALLI ESHWAR
IPC: H04B7/26
Filed: 1999-06-07
Abstract: Signal markers are placed in critical locations within the wireless network. Critical locations are locations where signals from base stations may be weak due to natural or man-made obstruction and locations where user demand for network resources may be particularly heavy. The signal markers collect data such as the signal strength or amplitude of signals from surrounding base stations, and the amount of user demand for access to the network. The signal markers then communicate this data to the mobile switching center. The mobile switching center analyzes the data and, if the data indicates unsatisfactory performance, determines new parameters for the base stations. The mobile switching center then communications the new parameters to each of the base stations where each of the base stations changes its performance in accordance with the new parameters.  The signal markers then once again collect data and communicate that data to the mobile switching center where further changes to base station parameters are made as necessary.
