Abstract: In an outboard motor control system, an electronic control unit executes ordinary navigation in which the operation of at least one among a steering motor, throttle motor and shift motor is controlled in accordance with an operator command inputted from the steering wheel or shift/throttle lever (steering command, shift position change command or engine speed regulation command of the outboard motor) and executes autopilot navigation in which the boat is automatically navigated by controlling the operation of the individual electric motors based on boat position information inputted from a GPS plotter and the desired position of the boat. This simplifies the configuration for conducting both manual navigation and automatic navigation and avoids making the system larger or more complicated to install, while including boat speed regulation and stopping capability among the autopilot features.

Abstract: Described herein are systems and methods for multiplexing pipelined data for backup operations. Various data streams are combined such as by multiplexing by a multiplexing module. The multiplexing module combines the data from the various data streams received by receiver module(s) into a single stream of chunks. The multiplexing module may combine data from multiple archive files into a single chunk. Additional modules perform other operations on the chunks of data to be transported such as encryption, compression, etc. The data chunks are transmitted via a transport channel to a receive pipeline that includes a second receiver module and other modules. The data chunks are then stored in a backup medium. The chunks are later retrieved and separated such as by demultiplexing for restoring to a client or for further storage as auxiliary copies of the separated data streams or archive files.

Title: Techniques de detection de pulsations cardiaques et de reduction de la consommation d'energie dans des capteurs
Inventor: NORDSTROM BRAD
IPC: A61B5/00
Filed: 2005-02-25
Abstract: L'invention concerne des techniques de basse puissance permettant la détection de pulsations cardiaques dans un signal provenant d'un capteur (101). Un bloc (102) de détection de pulsations détecte le signal du capteur et il détermine son rapport signal/bruit. Après comparaison du rapport signal/bruit avec un seuil, le courant d'attaque des éléments photoémetteurs dans le capteur est ajusté de façon dynamique pour réduire la consommation d'énergie tout en maintenant le rapport signal/bruit à un niveau adéquat. La composante de signal du signal du capteur peut être mesurée par identification de transitions systoliques. Les transitions systoliques sont détectées à l'aide d'un mécanisme de calcul de moyenne de dérivée maximum et minimum. Le minimum mobile (301) et le maximum mobile (304) sont comparés à la somme (312, 313) mise à l'échelle du minimum mobile et du maximum mobile pour identifier les transitions systoliques. Une fois la composante de signal identifiée, la composante de signal est comparée à une composante de bruit pour calculer le rapport signal/bruit.

Inventor: SULLIVAN PHILLIP F
IPC: C09K8/68
Filed: 2005-07-01
Abstract: A method is given for treating a subterranean formation penetrated by a wellbore with a viscosified fluid. The fluid contains a solid hydrolysable polyacid that upon dissolution and hydrolysis releases an acid that is a breaker for the viscosifying system. Suitable solid hydrolysable polyacids include polylactic acid and polyglycolic acid. The fluid also contains a pH  control agent, present in an amount sufficient to neutralize any acid present in the solid hydrolysable polyacid before the injection and to neutralize any acid generated by the solid hydrolysable polyacid during the injection, so that the acid breaker is not available to break the fluid during the injection. In one embodiment the viscosifier is a viscoelastic surfactant fluid system and the solid hydrolysable polyacid is of a size selected to be a fluid loss additive, for example in fracturing or gravel packing. In another embodiment, the solid hydrolysable polyacid is used in particles sufficiently small that they enter the pores of the formation. In either case, the viscosifier is broken after the solid releases more acid than can be neutralized by the pH control agent.
