Patent CA-2174177-A1 (CA)
Inventor: UEDA KEIICHI
IPC: H04B17/18
Filed: 1996-04-15
Abstract: In response to a testing instruction from a PHSC, the cell range of CS 4a is expanded from a range indi-cated by a solid line to another range indicated by a broken line in which CS 4a can communicate with CSs 4b, 4g and 4f as well as other CSs not shown adjacent to CS 4a.  Under the control of the PHSC, test calls are successively produced from CS 4a and transmitted to CSs 4b, 4g, 4f and all other adjacent CSs not shown to confirm the normality of connection.  Then, in a simi-lar manner as described above, the PHSC repeats this operation successively for all CSs and confirms. the normality of the CSs from obtained results.  When an abnormal condition is found out in a test result, the PHSC analogizes from a combination of test routes to specify the abnormal CS.

Inventor: TAKEFMAN MICHAEL LEWIS
IPC: H04N21/258
Filed: 1995-11-08
Abstract: A central station (24) of a cable television distribution network (10) transmits TDM frames comprising distribution information and overhead information downstream to customer terminals (26), and determines corresponding upstream TDMA frames by includ-an upstream frame identity in the overhead information of each downstream frame. Each terminal buffers asynchronous information for upstream transmission, and stores an upstream frame identity which it is assigned. On detecting this frame identity in the downstream overhead information, the terminal transmit a buffer queue size in an assigned time slot of the corresponding upstream frame The central station uses the queue sizes from the terminals to allocate time slots in the upstream frames to terminals, by including their terminal addresses in the downstream overhead information, for transmission of the buffered asynchronous information. The central station can also assign time slots to the terminals for transmission of isochronous information.

Patent CA-2196989-A1 (CA)
Title: Method and system therefor of establishing an acceptance threshold for controlling fraudulent telephone calls
Inventor: JORDAN DAVID P
IPC: H04M3/22
Filed: 1995-09-18
Abstract: The present invention advanced voice application system takes advantage of information, or attributes, built into a telecommunications network to determine the risk that a call is a fraudulent call in a voice recognition and verification system. To achieve this end, information relating to the telecommunications network is stored in a database as various risk factors.  Thus, depending on the type of risk factors associated with a particular call, the risk assigned to that call can be raised or lowered so that the network would not reject a valid caller even though the voice pattern of the caller does not match exactly with the prestored enrolled voice print of the caller.  Such risk assessment allows the management of the network to tighten the security of the system without overburdening the caller with questions and also permits calls to be completed for valid subscribers that otherwise would have been rejected. Past calling history may be added to the database as it relates to the different risk factors so that constantly updated risk factors may be used for further assessing whether a call is to be completed.

Title: Secure method and system for communicating a list of credit card numbers over a non-secure network
Inventor: BEZOS JEFFREY P
IPC: G06Q20/14
Filed: 1996-05-17
Abstract: A method and system for securely indicating to a customer one or more credit card numbers that a merchant has on file for the customer when communicating with the customer over a non-secure network. The merchant sends a message to the customer that contains only a portion of each of the credit card numbers that are on file with the merchant. The message may also contain a notation explaining which portion of each of the credit card numbers has been extracted. A computer (38) retrieves the credit card numbers on file for the customer in a database (40), constructs the message, and transmits the message to a customer location (10) over the Internet network (30), or other non-secure network. The customer can then confirm in a return message that a specific one of the credit card numbers on file with the merchant should be used in charging a transaction. Since only a portion of the credit card number(s) are included in any message transmitted, a third party cannot discover the customer's complete credit card number(s).

Abstract: In order to protect members adjacent to an invasive procedure on a body, the member to be protected is illuminated preferably with infrared light energy and the entire site of the invasive procedure is viewed through an optical system that conducts both infrared and visible light energy to one or more video cameras (127). Various structures may be employed to separate the visible and infrared light energies so that the signals representing such light energies may be processed separately and differently if desired and then recombined for display or separately displayed on a video color monitor (128). The site is illuminated by light from, in one instance, an endoscope (129). Situated between the source and the endoscope is a filter that blocks infrared light energy and provides color correction of the light provided to the camera(s).
