Patent CA-2006294-A1 (CA)
Title: Operator-defined dialog boxes and processing logic for computer systems
Inventor: GUTH GARY R
IPC: G06F17/21
Filed: 1989-12-21
Abstract: A computer system is provided for obtaining and recording information by presenting selected data, warnings and inquiries on a computer display monitor, prompting selected responses to the warnings and inquiries as desired, and integrating newly obtained information with other data to create a completed document. The system creates "dialog boxes" which are defined by an expert operator. To create a dialog box, the operator defines a location in the document in which a question is to be asked or information provided to the user. The operator also defines the question or information, and can also provide several responses to the question. The operator can specify the number of answers which can be accepted in response to an inquiry, and can specify that certain information, such as a date or the like, be provided. The dialog boxes can be arranged in an information tree structure having multiple branches. The branches of the tree which are actually used are determined by the responses received to inquiries as information is obtained. Macros can also be integrated into the tree structure, if desired. The operator's selection of sequential responses to the questions thereby determines how the document develops. As questions are answered, the information obtained is inserted into the text of the completed document, and the inquiries are erased. In this manner, someone having expert knowledge in a field other than computer programming can develop a system which persons with less knowledge in the field can use to obtain information and assemble it in an integrated and easy to understand narrative text format.

Title: A predictive access-control and routing system for integrated services telecommunication networks
Inventor: KHERADPIR SHAYGAN
IPC: H04M3/00
Filed: 1990-02-09
Abstract: A predictive access-control and routing system for a telecommunications network operating in uncertain environments and capable of handling heterogeneous traffic. The system is a real-time, state-dependent network traffic control system in which the control strategy is a function of both real-time congestion levels and real-time traffic profiles. At specific time epochs, the system, using real-time measurements of source-destination arrival dates and trunk group link occupancies, generates predictions of all network trunk group occupancy levels for the next epoch as a function of routing and access control. It then minimizes a projected cost function, such as blocking, to generate a traffic control policy to be implemented during the next time interval.

Abstract: S P E C I F I C A T I O N               "A Railway Wagon Retarder"               ABSTRACT OF THE DISCLOSURE           The retarder  is  installed  adjacent  a railway track for  reducing the speed of a wagon rolling along the track and additionally has the capability  of boosting the speed of  a wagon.  The retarder includes a hydraulic unit having a portion adapted to be  deflected out  of the path of  a  wheel  of  the  wagon  when  directly or indirectly engaged by the  wheel  before  returning  to  its original position.    The unit  has  adjustable  hydraulic damping capable of resisting such deflection to  retard the wagon, and a  wagon speed  responder for  adjusting the hydraulic damping of the unit to retard  a wagon  travelling at high speed.    The  retarder  further  includes  a regenerative source of hydraulic fluid under pressure  connected to the unit by  a selector  valve such  that, when a wagon passes over the unit  travelling  at  high  speed,  the resultant retarding operation of the unit results in charging of the regenerative source with hydraulic fluid , whereas, when a wagon subsequently  passes over the unit travelling at low speed, hydraulic fluid under  pressure is  supplied to the unit  from  the  regenerative  source to cause boosting of the speed of the  wagon by  forced return  displacement of the portion  in direct or indirect engagement with a wheel of the wagon.

IPC: H04J3/08
Filed: 1990-06-15
Abstract: In the transmission of digital signals in time-division multiplex via a transmission link with repeater stations at which time slots are either only dropped are also reoccupied, the problem arises of continuing to maintain the information transmission even with an alarm triggered in a repeater station. The invention provides for a bypass circuit (11) via which the repeater station is bypassed when an alarm is triggered in it. If a reoccupation of the time slots is intended, the bypass circuit (11) in this arrangement can send a message to the neighbouring repeater stations and/or the line terminating device for allowing the reallocation of time slots which have not been reoccupied in the repeater station. If the time-division multiplex signal contains a service channel, messages can be sent to the neighbouring repeater stations and follow-up measures initiated via this channel. <IMAGE>
