Title: Navigation apparatus with improved attitude determination
Inventor: BROCKSTEIN ALLAN J
IPC: G01C21/16
Filed: 1995-09-11
Abstract: The navigation apparatus with improved attitude determination is intended for use on a mobile platform.  It combines data from a platform inertial navigation unit and carrier phase data for a plurality of GPS satellite signals received at a plurality of receiving points on the platform for the purpose of obtaining estimates of the navigation states of the platform.  The navigation apparatus comprises a processor which computes estimates of the states from inputs comprising (1) one or more measured phase double-differences calculated from the measured satellite signal carrier phases, (2) the estimated position of the platform, (3) the estimated positions of the receiving points, and (4) the positions of the satellites, a phase double-difference being defined as the difference in phase differences for signals received from two satellites and a phase difference being defined as the difference in carrier phase of a satellite signal received at two receiving points. The navigation and attitude determination solution is obtained by means of a Kalman filter process wherein the observables comprise measured phase double-differences and each predicted phase double-difference is obtained by operating on the Kalman state vector with an observation matrix defined by linearizing  the equations relating the phase double-difference to the navigation states.

Abstract: Sont décrit un système et un procédé perfectionnés pour transmettre des informations par des voies de transmission en phase (I) et en quadrature (Q) dans un système de transmission à spectre étalé. Dans un exemple de mode de réalisation, des premier et deuxième signaux d'information (a¿n?, b¿n?) sont transmis respectivement sur les voies de transmission en phase et en quadrature à l'aide de signaux de transmission à spectre étalé à séquences directes. Des signaux de bruit pseudo-aléatoire en phase (PN¿I?) et de bruit pseudo-aléatoire en quadrature (PN¿Q?), ayant des codes PN prédéterminés (178, 180), sont utilisés respectivement pour étaler le spectre des premier et deuxième signaux d'information (a¿n?, b¿n?). En particulier, les signaux PN¿I? et PN¿Q? sont respectivement combinés avec les premier et deuxième signaux d'information (a¿n?, b¿n?) et un signal de fonction orthogonale (174) pour donner des signaux de modulation de la voie I et de la voie Q (S¿I?, S¿Q?). Ces derniers sont utilisés pour moduler des signaux multiplex en phase (I) et en quadrature (Q) en vue de leur transmission à un récepteur par l'intermédiaire de voies de transmission I et Q, respectivement. Dans un mode préféré de réalisation, le récepteur agit pour produire une estimation d'au moins le premier signal d'information sur la base des signaux multiplex (R¿I?), R¿Q?) modulés sur la voie I et la voie Q et reçus sur les voies de transmission I et Q. Ces signaux multiplex (R¿I?, R¿Q?) modulés reçus sont démodulés et leur spectre est désétalé, les séquences résultantes étant corrélées pour donner des signaux de projection en phase (I) et en quadrature (Q). Un déphaseur sert à fournir une estimation d'au moins le premier signal d'information sur la base de signaux de projection I et Q et d'un signal pilote reçu.

Abstract: The invention provides a code amount controlling method wherein, when code amount control is performed in units of a GOP, data do not remain in a buffer even if data with which a moving picture comes to an end intermediately of the last GOP are compressed. A control parameter setting section gets the number of frames from among all frames of picture data of an object of compression for which coding processing has not been performed, gets the number of frames in one GOP, and discriminates from the remaining frame number and the frame number in the GOP whether or not coding processing comes to an end intermediately of the last GOP. When coding processing comes to an end intermediately of the last GOP, the last GOP and a directly preceding GOP are coupled to vary the frame structure, and an aimed code amount is calculated. Also another method wherein all aimed code amount of the last GOP is compulsorily determined making use of an aimed code amount of the preceding GOP may be utilized. Using the thus obtained aimed code amount, a Q-scale of the macroblocks is calculated and compression coding is performed.

Title: Process for fixing an image
Inventor: EHRET ANNE
IPC: G03F7/004
Filed: 1995-04-25
Abstract: A process for producing and fixing an image uses an imaging medium comprising an acid-generating layer or phase comprising a mixture of a superacid precursor, a sensitizer and a secondary acid generator, and a color-change layer comprising an image dye.  The sensitizer can absorb radiation of a sensitizer wavelength which does not, in the absence of the sensitizer, cause decomposition of the superacid precursor to form the corresponding superacid.  The secondary acid generator is capable of acid-catalyzed thermal decomposition by the first acid to form a secondary acid, and the image dye undergoes a color change upon contact with the secondary acid.  The medium is imagewise exposed to radiation of the sensitizer wavelength, thereby causing the sensitizer, in exposed areas, to decompose superacid precursor with formation of the first acid.  The medium is then heated to cause, in the exposed areas, acid-catalyzed thermal decomposition of the secondary acid generator and formation of the secondary acid.  The components of the acid-generating and color-change layers or phases are mixed so that in exposed areas, the secondary acid causes the image dye to change color.  At least the non-exposed areas, there is reacted with the superacid precursor a reactive material which irreversibly destroys the superacid precursor, thus fixing the image.

Title: Treatment of alzheimer disease by modulation of synapsins
Inventor: GREENGARD PAUL
IPC: A61K31/465
Filed: 1996-05-13
Abstract: The role of synapsin II in both the reformation and the maintenance of synaptic connections in cultured hippocampal neurons can be the basis of therapy for neurodegenerative disorder, particularly Alzheimer disease, which involve the disruption of synapses. When synapsin II expression in neurons is blocked by antisense synapsin II oligonucleotides, the ability of hippocampal neurons to reform as well as to maintain synapses is severely disrupted. Antisense suppression of synapsin II after axon formation but immediately before synaptogenesis prevents synapse formation. Suppression of synapsin II after synaptogenesis disrupts the majority of existing synapses. Re-expression of synapsin II in synapsin deficient neurons achieved after removing the antisense oligonucleotides leads to the re-establishment of synaptic connections, providing direct evidence that synapsin II is required for the maintenance and/or restoration of synapses. Thus, therapeutic methods based on the reformation and the maintenance of synapses, including delivery of the synapsin cDNAS or proteins into the patient's nervous system, use of the synapsin cDNAS to promote the synapse forming ability of cells for grafting, and use of agents that increase the expression of, enhancing the activity of, or mimic the activity of, the endogenous synapsins, can provide treatment of neurodegenerative disorders.
