Abstract: A carrying tray assembly for the rear of a sport utility vehicle. The assembly is suspended from sections of the sports bar arrangement and permits easy access to any items on the tray of the assembly. The assembly also permits other gear to be placed below the tray on the floor of the rear deck of the vehicle and covered with a tonneau if desired to protect the gear from the elements.      The assembly has front and rear supporting systems that are adjustable to fit a variety of sport bar designs.      Additionally, because the tray is suspended from sections of the sports bar arrangement rearwardly of the driver's and front passenger's seats, traditional half tops and windscreens can also be used on the vehicle at the same time as the carrying tray assembly.

Title: Inferential signal generator for instrumented equipment and processes
Inventor: WEGERICH STEPHAN W
IPC: G01H11/00
Filed: 2001-11-21
Abstract: An improved system and method for producing replacement sensor signals for failed sensors (150), and inferred sensor signals (160) for non-instrumented physical parameters, in processes and equipment having one or more sensors in place for monitoring physical parameters. A data history from a fully-instrumented prototype (110) provides a representative data set of anticipated operating parameters for forming an empirical model for generating "virtual"  signals for a process or machine in real-time. A memory (551) for storing the representative training set, or a transformation thereof, is coupled to a processor (545). The processor (545) receives from an input, data signals embodying real values from sensors on the process or machine. The processor (545) takes a set of readings of the actual sensors from the input, and generates an estimate of one or more desired inferred sensors, using a linear combination of the representative training set sensor data, as weighted by the result of a measure of similarity of the input data to the representative data.

Abstract: La présente invention concerne l'hybridation d'acide nucléique dans des conditions stables par un modèle cinétique dans lequel on considère que l'état intermédiaire est localement monocaténaire. Une expression a été dérivée, et elle relie la structure secondaire d'acides nucléiques à la vitesse d'hybridation d'ARN d'oligonucléotide. Ce modèle considère que l'hybridation des acides nucléiques survient via un état intermédiaire dans lequel la région à hybrider possède une conformation monocaténaire avant la liaison de l'oligonucléotide antisens. Dans cette dérivation, un état stable est supposé. Ce modèle est applicable à un état stable dans des cellules vivantes et à l'étape initiale d'hybridation monotube lorsque l'hybride de pleine longueur n'a pas accumulé de façon importante et que la concentration de complexe de nucléation est approximativement constante. Ce modèle permet de calculer un facteur de vitesse qui est proportionnel à la constante de vitesse d'hybridation entre des acides nucléiques complémentaires. Lorsque des facteur de vitesse sont calculés à l'aide d'un algorithme disponible sur le marché de façon à estimer la structure secondaire d'ARN, ils donnent une bonne corrélation aux vitesses d'hybridation des oligonucléotides antisens (ODN) avec un ARN artificiel de nucléotide 101 qui a été publié et de balises moléculaires rattachées à l'ARNm tat du VIH-1. Pour la renaturation ARN-ARN, les localisations des régions longues de nucléotides 11 qui possèdent le facteur de vitesse maximum coïncident avec des sites de nucléation déterminés expérimentalement. La dépendance du facteur de vitesse maximum par rapport à la longueur de l'ARN antisens est en conformité avec la relation observée entre les vitesses d'hybridation et les longueurs d'antisens. Les facteurs de vitesse calculés pour 32 sites dans l'ARNm d'intégrase de VIH 1 sont également corrélés avec l'hybridation de l'ODN antisens à chaque site lorsqu'ils sont mesurés par clivage dépendant de la ribonucléase H induite par ODN. Ce modèle identifie des sites qui s'hybrident immédiatement sur une plage de concentration ionique de magnésium supposés affecter la structure tertiaire d'ARN, suggérant que cette structure tertiaire est soit absente, soit de peu d'importance dans l'hybridation. Les facteurs de vitesse de site cible calculés correspondent aussi aux données publiée de l'hybridation d'oligonucléotide antisens avec l'ARNm de gènes humains, codant pour la résistance à de multiples médicaments, le récepteur de type 1 d'angiotensine, c-myb, l'acétylcholinestérase et le virus de l'hépatite C. Ces résultats prennent en charge l'applicabilité générale du modèle cinétique et son utilité potentielle pour une identification rapide de sites d'attaque antisens d'ARNm.

Abstract: A method and system for compensating for side effects of cross gain modulation in amplified optical networks, which allows reliable identification of expected and unexpected channels in the network is provided. Each optical channel traveling in the optical network is marked with a unique channel signature (expected channel signature), having one or more dither tone modulated onto the optical channel; followed by detecting a spectrum of tones, including said modulated dither tones and ghost tones thereof produced by the cross gain modulation in the optical network, at various locations in the optical network. Amplitudes of the spectrum tones, which belong to the expected channel signature, are compared with a first threshold, while amplitudes of the remaining spectrum tones, which are not the valid tones, are compared with a second threshold, which is lower than the first threshold. The spectrum tones are identified as valid tones if their amplitudes are above the first threshold; and an alarm signaling that the expected channel signature is missing is generated if the amplitude of the spectrum tone is below the first threshold. Yet another alarm is generated signaling that an unexpected channel is detected in the network if the amplitude of at least one of the remaining spectrum tones is exceeding the second threshold. Alternatively, the other alarm is generated if amplitudes of the remaining spectrum tones belonging to one of the allowable channel signatures in the network are above the second threshold. A corresponding system incorporating the step of the methods described above is also provided. 25
