Patent CA-2333763-A1 (CA)
Inventor: CHARAIS JOHN R
IPC: H04B17/00
Filed: 1999-06-02
Abstract: In a wireless security system, the system controller includes one or more antennas for reception of signals from remote sensor-transmitter units. To detect antenna failure, the system controller generates a test signal with a known parameter and transmits this test signal via a first antenna. The system controller then measures the parameter of the corresponding test signal received, if any, via a second antenna, and compares the parameter of the corresponding test signal received to a predetermined threshold parameter.  When the parameter of the test signal received via the second antenna differs from the threshold by a predetermined amount, or predetermined margin for error, an antenna failure message is generated.

Title: Precision-controlled duty cycle clock circuit
Inventor: WYNEN JOHN
IPC: H03K5/156
Filed: 2001-01-09
Abstract: A clock signal duty cycle control circuit is provided that receives an incoming signal from a clock signal input source and generates an improved output clock signal having an accurately controlled duty cycle. The circuit controls the duty cycle of the output clock signal by comparing the incoming signal to a reference value in a comparator. The reference value is derived from a reference charge stored on a capacitor. The reference charge is built up in the capacitor using the currents from a current source and a current sink, which are controlled using translated output signals from the comparator.

Title: Method and apparatus for effecting telecommunications service features using call control information extracted from a bearer channel in a telecommunciations network
Inventor: MARKMAN ALEXANDER
IPC: H04Q3/00
Filed: 2001-05-28
Abstract: A system and method provide a call service features in response to call control information conveyed by a monitored bearer channel in a telecommunications network. A bearer channel monitor captures the call control information and relays the information to a call control application server. The call control application server analyzes the call control information, and provides call control instructions to a call control node that operates in the telecommunications network to effect the call service. The call control node serves as one or more virtual switching points in the network to directly control call routing without disconnecting a called or calling party, unless required as part of a service feature. Control from a center of the telecommunications network provides rapid and efficient call control without use of edge devices or duplication of bearer channels in the network.

Title: Trust model router
Inventor: MILADINOVIC JOVAN
IPC: H04L29/06
Filed: 2001-06-19
Abstract: A system and method for bridging between trust models allows parties to an e-commerce transaction to use different trust models, while still effecting the transaction with all of the necessary safeguards and comforts which would be available by effecting the transaction within a single trust model. A trust model router implements security technology that provides an interface between existing trust models and provides for the usage of disparate technologies in an e-commerce transaction. The trust model router comprises a set of secure check rules, which determine to which trust model the information should be routed and what type of certification technology should be used. Based on information obtained by an issuing certificate authority, the trust model router of the invention determines the type of trust model to be used in the transaction and follows rules-based procedures consistent with the trust model to properly record and complete the transaction. The trust model router is trusted to perform transaction routing on a behalf of a trusted model, because it is certified by the participating trust model or transaction standards frameworks.
