| 20100238030 | MOTION DETECTOR HAVING ASYMMETRIC ZONES FOR DETERMINING DIRECTION OF MOVEMENT AND METHOD THEREFORE - A detector, system including a detector and method for sensing motion within a detection region. The detector has a detection element and a focusing element aiming received energy corresponding to a presence within the detection region toward the detection element. The focusing element has a plurality of sections in which each of the plurality of sections establishes a corresponding detection zone within the detection region. The plurality of sections are arranged to allow a motion vector to be determined for an object passing through the detection region. The system includes a detector that generates pulses each time presence in a detector zone is detected as well as a central alarm panel. The central alarm panel receives the pulses and has processor that evaluates the timing between electrical pulses to determine the motion vector. | 09-23-2010 |
| 20090323904 | METHOD AND APPARATUS FOR COMMUNICATION BETWEEN A SECURITY SYSTEM AND A MONITORING CENTER - A method for providing communications between a system control panel at a premises and a central monitoring center comprises transmitting an event code from the control panel to the monitoring center utilizing a first communications format and a network protocol, and causing the control panel to enter a call-back mode. The control panel is enabled to receive in-bound calls utilizing a second communications format. A two-way voice session is established utilizing the second communications format between the monitoring center and the control panel. The two-way voice session is initiated by the monitoring center. | 12-31-2009 |
