Title: Intelligent prompting
Inventor: GOLTRA PETER S
IPC: G16H70/60
Filed: 1997-02-25
Abstract: A method and apparatus for helping health care professionals create clinical protocols or assist in direct entry of medical finding into a chart by intelligently prompting a health care professional with medical findings associated with at least one medical finding which has already been entered in the protocol, is disclosed (fig. 2). First of all, at least one medical finding for a patient is inputted into the system (10) wherein each findings is assigned a point of value for each diagnosis within a knowledge base (22).  A total number of points for each diagnosis is then totalled for all the findings which have been entered into the system (10). The possible diagnoses are then ranked in descending point total and predetermined plurality of the highest ranked diagnoses are selected. Once the higher ranked diagnoses have been selected, the health care professional is prompted with additional findings associated with the selected diagnoses which have not yet been inputted into the clinical protocol.

Title: Fourier detection of species migrating in a microchannel
Inventor: PARCE J WALLACE
IPC: G01N21/85
Filed: 1997-07-14
Abstract: The present invention provides a microfluidic system (100) for fast, accurate and low cost electrophoretic analysis of materials in the fields of chemistry, biochemistry, biotechnology, molecular biology and numerous other fields. Light from periodically spaced regions along a channel (110) in the microfluidic system are received by the photodetector (130). The intensity of light received by the photodetector is modulated by the movement of species bands (123) through the channel under electrophoretic forces. By Fourier analysis, the velocity of each species band (123) is determined and the identification of the species is made by its electrophoretic mobility in the channel (110).

Inventor: COSENTINO CHRISTOPHER
IPC: A47C7/46
Filed: 1999-02-02
Abstract: A connection between a tensile element and an object is described having a slotted plate, a connector and a retainer. The slotted plate is attached to or part of the object and the slot has a first part and a second part.  The connector has a first end that is engageable with the tensile element and a second end that can be inserted into the second part of the slot and slid towards the first part of the slot to engage the first part of the slot.

Title: Method of controlling paging in a plurality of mobile switching centers in a radio telecommunications network
Inventor: HOUDE MICHEL
IPC: H04W68/12
Filed: 1997-12-09
Abstract: A method of paging for a mobile station operating in a radio telecommunications network having a serving mobile switching center (MSC) (13), a home location register (HLR) (12), and a plurality of border MSCs (15, 17). The method comprises the steps of paging for the mobile station in the serving MSC, and sending an intersystem paging message (26, 27) from the serving MSC to each of the plurality of border MSCs. The intersystem paging message includes an instruction to page the mobile station (56), an indication of a number of page attempts to perform (55), and an indication of a page response time for each page attempt (57). A total page response time is calculated in the serving MSC by taking into account the entry time of a Routing Request Invoke message, the signaling delay in the border system, the average time for designation of a voice channel, and an additional average time for transferring the call to voice mail in the event of a no page response condition. If a page response (31) is received in one of the border MSCs (15) prior to expiration of the maximum time period for completion of the page attempts, the method stops internal paging in the serving MSC and may send a release message (37) from the serving MSC to the non-responding border MSCs (17) from which no response was received, to release paging resouces in the non-responding border MSCs. If no page response is received within the maximum time period allowed, the HLR may initiate transfer of the call to voice mail.

Abstract: L'invention concerne un procédé permettant d'attribuer une identification internationale temporaire unique à une station mobile durant l'établissement et le rétablissement d'une liaison logique entre une station mobile et le noeud support (SGSN) du service général de radio par paquets (GPRS) serveur. L'identification internationale temporaire unique permet de passer les frontières sans utiliser l'identité internationale de station mobile (IISM), c'est-à-dire de sortir de la zone de couverture du réseau mobile terrestre public (PLMN) de rattachement. L'invention suggère de constituer une nouvelle identité comprenant l'ancienne identité temporaire de liaison logique (TLLI), l'ancienne zone d'acheminement (RA) et l'identité du réseau PLMN propriétaire de l'ancienne TLLI et le pays auquel appartient le PLMN. La nouvelle identité est utilisée comme identité sur l'interface radio, comme identité à l'intérieur du SGSN actuel et pour l'identification de l'ancien SGSN.

Abstract: An apparatus and method for determining a program neighborhood of a client node in a client-server network is described. The program neighborhood of the client node includes application programs hosted by application servers on the network. The present invention enables a user of a client node to learn of these application programs. The user is not required to know where to find such applications or to manually establish links to such applications. To make the client node aware of its program neighborhood, a host server collects application-related information corresponding to application programs hosted by the servers in the network. The application-related information can include the application name, the server location of the application, minimum capabilities required of client nodes for executing the application, and those users who are authorized to use that application. User credentials are received from the client system. The user credentials are used to filter the application-related information. Information representing those application programs that are available to the client node is transmitted from the host server to the client system for display. In a Windows-based client node, the information can be represented by a graphical icon for each available application Program.
