Patent CA-2453754-A1 (CA)
Title: Remote control system for a locomotive
Inventor: HORST FOLKERT
IPC: B61L3/12
Filed: 2003-12-19
Abstract: A system for controlling a locomotive, including a plurality of portable communications units, each unit adapted to generate signals conveying commands indicative of functions to be performed by the locomotive. Each unit is also associated with an operational status; the signals generated by each unit have a characteristic dependent on the operational status associated with that unit. Also, the system includes a controller adapted to receive the signals generated by the plurality of portable communications units, to determine the commands conveyed by the received signals and to control the locomotive on the basis of the decoded commands. By making each portable transmitter unit aware of its operational status, battery power can be conserved and airwave congestion reduced by precluding the transmission of commands that are guaranteed to be rejected because of the lack of command authority of an originating unit.      Meanwhile, the unit which holds command authority continues to be able to send a complete set of commands.

IPC: A61B5/00
Filed: 2002-07-17
Abstract: La présente invention concerne un procédé et un appareil permettant de surveiller les alarmes d'un appareil de diagnostic médical dans lequel une alarme se déclenche lorsqu'une valeur mesurée d'un paramètre physiologique est située en dehors d'une plage spécifiée. Ce procédé calcule en continu une valeur de base et établit des seuils dynamiques liés à cette valeur et ces seuils suivent en continu cette valeur de base. Ce procédé détermine la durée durant laquelle la valeur mesurée dépasse le seuil dynamique et la quantité de dépassement de ce seuil. Des alarmes se déclenchent sur une combinaison de cette durée et de cette quantité de dépassement du seuil. Cette combinaison est, de préférence, une intégrale ou la fonction d'une intégrale.

Inventor: TUNKELANG DANIEL
IPC: G06F17/30
Filed: 2002-08-09
Abstract: Provided is a similarity search method that makes use of a localized distance metric. The data includes a collection of items, wherein each item is associated with a set of properties. The distance between two items is defined in terms of the number of items in the collection that are associated with the set of properties common to the two items. A query is generally composed of a set of properties. The distance between a query and an item is defined in terms of the number of items in the collection that are associated with the set of properties common to the query and the item. The properties can be of various types, such as binary, partially ordered, or numeric. The distance metric may be applied explicitly or implicitly for similarity search. One embodiment of this invention uses random walks such that the similarity search can be performed exactly or approximately, trading-off between accuracy and performance. The distance metric of the present invention can also be the basis for matching and clustering applications. In these contexts, the distance metric of the present invention may be used to build a graph, to which matching or clustering algorithms can be applied.
