Patent number: 7715550Abstract: A telephone line interface and side-tone attenuation circuit includes two opto-electric converters. The first has an input interconnected to receive a signal proportional to a near-end signal, and an output interconnected to modulate a current proportional to the near-end signal onto the subscriber loop. The second has its input interconnected to provide a signal proportional to a current on the subscriber loop, including the current proportional to the near-end signal, at its output. A summing amplifier receives signals proportional to the output voltage of the second opto-electric converter and a signal proportional to the near-end signal. The output voltage of the second opto-electric amplifier includes a component that is substantially 180° out of phase with the near-end signal, allowing the near-end signal to be cancelled at the summing amplifier.Type: GrantFiled: September 8, 2005Date of Patent: May 11, 2010Assignee: Tyco Safety Products Canada Ltd.Inventor: Reinhart K.

Publication number: 20100066487Abstract: A system and method are disclosed for using a single key to authenticate a user with respect to multiple user access points and to allow a single access point to authenticate multiple keys having different physical characteristics. The system may comprise an access control system that includes an insertion receptacle for receiving a physical key, and a translation device for observing the physical characteristics of the key and translating those characteristics into electrical signals. In a learning mode, the electrical signals are transmitted to a processor and stored in memory. In a verification mode, the electrical signals are transmitted to the processor and compared with the previously-stored signals. If the processor concludes that the signals match the signals stored in memory, then the processor instructs a lock actuation mechanism to actuate an access control device to allow the user access to a location.Type: ApplicationFiled: May 11, 2009Publication date: March 18, 2010Applicant: Tyco Safety Products Canada Ltd.Inventor: DWAYNE A.

Patent number: 7583726Abstract: A method for transferring data over a communication link using a data rate and a voice modem not designed to provide communications at the data rate, includes generating, in a processor, a modulated Frequency Shift Keying (FSK) signal from an outgoing data stream. The voice modem, in playback mode, plays the modulated FSK signal over the communication link. The voice modem, in record mode, receives voice data from the communication link and sends the voice data to the processor, which demodulates any FSK signal that is present in the voice wave data to produce an incoming data stream.Type: GrantFiled: September 20, 2005Date of Patent: September 1, 2009Assignee: Tyco Safety Products Canada Ltd.Inventors: Jeremy Elliott, James Long

Publication number: 20090146801Abstract: An emergency evacuation and fire safety system has a plurality of signal devices. The clock source frequencies are tuned using the method and system such that the signals flash in synchronization continuously at a preset flashing interval upon detecting an alarm condition. A synchronization signal including a calibrated time position is broadcast at each predetermined time interval to all notification appliances. A time difference is computed between a local time position and the received calibrated time position by each of the notification appliances at each predetermined time interval and tuning the flashing of each of the one or more notification appliances by adjusting the preset flashing interval based on the computed time difference by each of the one or more associated notification appliances.Type: ApplicationFiled: December 6, 2007Publication date: June 11, 2009Applicants: SimplexGrinnell LLP, Tyco Safety Products Canada Ltd.Inventors: Joseph Piccolo, III, Maxime Fortin, Laurent Veilleux, Daniel Lauzon

Patent number: 7474226Abstract: A method for calibrating a smoke detector includes adjusting the sensitivity of the smoke detector to get a consistent predetermined response over the expected operating range. The sensitivity is generally consistent for all detectors and an independent offset value is determined for each detector. This offset value basically corresponds to the signal from the detector in a clean atmosphere. The sensitivity of the smoke detector is determined by measuring the response at different levels of obscuration and then appropriately adjusting the output of the light source of the detector. This process is repeated until the desired sensitivity is achieved. Thereafter, the offset value is measured or calibrated and stored in the smoke detector for use in setting alarm values.Type: GrantFiled: April 9, 2007Date of Patent: January 6, 2009Assignee: Tyco Safety Products Canada Ltd.Inventors: Zhexin Mi, William J.
