Abstract: Procédé et appareil permettant de corriger la dérive thermique dans des mesures de débit cardiaque qui se fondent sur un signal de température indiquant la variation de température du sang à la sortie du coeur. Dans un premier mode de réalisation préféré de ce système de surveillance (10) du débit cardiaque, le cathéter (14) est pourvu d'un dispositif de chauffage ohmique (22). Un courant électrique présentant une forme d'onde sinusoïdale d'une période comprise entre 30 et 60 secondes est appliqué au dispositif de chauffage, ce qui entraîne une dissipation d'énergie électrique dans le sang à l'intérieur du coeur (12) d'un patient. Un capteur de température (24) disposé à proximité de l'extrémité distale du cathéter produit un signal indiquant la température du sang au sortir du coeur. Ce signal de température et le signal correspondant à l'énergie électrique dissipée dans le dispositif de chauffage (signal d'entrée) sont filtrés à une fréquence  omega n correspondant à la fréquence du courant électrique appliqué, c'est-à-dire la fréquence du signal d'entrée. Un signal de sortie indiquant la température du sang au sortir du coeur, corrigé par rapport aux effets de la dérive thermique, est ensuite calculé. Le signal de sortie de température sanguine est d'abord divisé en deux périodes égales qui se recouvrent. Les deux signaux sont ensuite séparément filtrés de sorte que deux signaux de sortie partiellement indépendants soient produits dans le domaine de fréquence. Ces deux signaux de sortie dans le domaine de fréquence sont ensuite combinés en un seul signal de sortie corrigé dans le domaine de fréquence, duquel les effets de la dérive thermique ont été enlevés. L'amplitude de l'énergie d'entrée, l'amplitude du signal de température corrigé par rapport à la dérive thermique, et leur différence de phase sont ensuite utilisées pour calculer le débit cardiaque.

IPC: H04L9/26
Filed: 1998-07-10
Granted: 2001-05-01
Abstract: A confusion data generator for the generation of non-linear confusion data utilizes a plurality of arrays acting as non-linear state machines to generate a stream of confusion data of a certain width. Each non-linear state machine contributes equally to the overall width of the confusion data. The output bit stream from the confusion data generator is then used with a combiner such as an XOR combiner to generate secure text from plaintext. The confusion data generator can be used to securely store data on a storage medium or transmit data over a communication medium. The confusion data generator is computationally inexpensive, scalable and provides good security when used with a combiner, such as an XOR combiner, to generate secure text.

Abstract: The present invention provides a laser tracking system including a laser generator for generating a beam of laser energy, a beam steerer for steering the beam of laser energy such that it moves in a search pattern, and a receiving device that receives laser energy reflected from a targeted object and that causes the beam steerer to vary the search pattern in response to the reflected laser energy. A tracking method associated with the laser tracking system includes the steps of generating a beam of laser energy, steering the beam of laser energy in a search pattern, detecting a hit spot formed from laser energy being reflected from a targeted object, diminishing the size of the search pattern in response to the detection of the hit spot, and focusing the diminished search pattern on a feature of the targeted object corresponding to the hit spot. The laser tracking system and associated method presented provide a number of advantages over conventional tracking systems. The laser tracking system employs closed loop methodologies allowing the system to accurately track targeted objects using continuously updated tracking data. The laser tracking system is able to seek and lock on to vulnerable features of potential targets. Further, the laser tracking system is able to maintain a desired aim point indefinitely and without operator intervention. This aim point maintenance allows an associated weapon to disable a target, despite any relative tracker-target motion during the munitions launch and flight.

Abstract: A method for efficiently searching free space in a relational database management system. The method limits the search to a finite number of space map pages in the free space map. If the configured number of space map pages in the free space map are searched and a page with free space is not found for the row, the row is inserted on the last page, or if no space is available on the last page a new page is created and the row is inserted on the new page. New rows are then appended until some predefined amount of space is filled before a search is done again. As a result, insertion of a row into the database management system does not incur the worst-case cost of searching the entire free space map.

Abstract: A computer-readable system and method for interpreting and selectively forwarding an interpreted message derived from a user's received electronic message, such as an e-mail, fax, converted voice and pager messages, to a mobile communications device of the user. A structured knowledge base comprises knowledge objects of user-related information and the knowledge objects are interlinked by semantic links to permit dynamic navigation thereof. Navigating means dynamically navigates through the structured knowledge base using the content of the received message and determines key term(s) relating to the content as a result of the navigating. An interpreted message is determined from those key term(s). Prioritizing means determines the priority of the message, selects the second communications device based on the current context of the user and the content of the message in relation to the user-related information and assigns priority indicia to the interpreted message according thereto. Forwarding means forwards the interpreted message to the second communications device when the priority indicia assigned to the interpreted message represents that the interpreted message is to be so forwarded.

Abstract: A snow removal device that picks up snow from the ground and flicks the snow into impeller units that transport the snow into a discharge tube whence the snow is expelled from the system. The system primarily includes a pick-up assembly, an impeller assembly, and a discharge tube. The pick-up assembly has a drum array that includes rows of triple-stepped blade-like fingers distributed evenly around each drum of the array of drums. These fingers are stiffly flexible and can cleanly and efficiently pick up snow from uneven ground surfaces and flick the snow into the impeller assembly that is mounted parallel to the axis of the drum array. The impeller assembly includes a plurality of impeller units that transport the snow into the discharge tube. The impeller units are reversible in direction, allowing the snow to be discharged to the right or the left of the system, or to the right and left simultaneously. The discharge tube and the impeller assembly lie in the same plane and are tilted upward approximately 20° relative to the ground. Thus, the snow is discharged at a relatively low height to the ground. The discharge tube and impeller assembly can be pivotally attached to the floating chassis, allowing the plane of the impeller assembly and the discharge tube to be tilted at a steeper angle relative to the ground. The snow removal device may be pulled or pushed by a prime mover and powered by an externally mounted hydraulic system.

Abstract: Broadband energy incident on a transducer having partially or fully reflective surfaces separated by a gap which is greater than the coherence length of the broadband energy but smaller than one-half a coherence length of a band of energy within said broadband energy causes a portion of the spectral content of the broadband energy corresponding to a coherence length greater than twice the gap length to exhibit interference effects while the average power of the broadband energy remains unaffected. Splitting energy reflected from the transducer into two beams which are filtered at preferably similar center frequencies but with different pass bands yields beams which are radically different in sensitivity to changes in gap length. Analyzing the beams to derive a ratio of powers (since source intensity and fiber attenuation in a common fiber are thus self-cancelling) allows high accuracy and high resolution absolute measurement of temperature, pressure or strain.

Abstract: At least portions of the map of the base stations, i.e., which base stations are neighbors, is discovered and updated using a wireless terminal controlled handoff process. The portion of the map that is discovered by a particular base station is typically its neighbors to which it can possibly hand off a call it is serving. It takes at least one handoff with each such base station neighbor for the particular base station to discover its entire local map, i.e., all the base stations to which the particular base station can perform handoffs. The wireless terminal handoff process is used to supply a base station with information about other base stations with whom the base station can cooperate to perform handoffs. The handoff process may subsequently be performed more expeditiously between the particular base station and such other base stations using the obtained information. As part of the handoff process, the wireless terminal tells the new base station to which it is handing off the call the identity of the previous base station from which control is being handed off. The wireless terminal then completes handoff and begins to be served by the new base station. If the new base station does not have a valid record for the previous base station, it forms a trust relationship with the previous base station and creates a record for it, thus identifying it as a neighbor to which it can perform expedited handoff in response to the control of a wireless terminal.
