Patent number: 7786880Abstract: A smoke detector having a closed internal optical path can detect airborne particulate matter, such as smoke from a fire, via a light scattering sensor and/or a light absorption sensor. The path can be implemented with a plurality of reflectors, such as piezoelectric minors. Input light can be coupled to the path, on a pulsed basis, for example via one of the minors, in a resonant condition.Type: GrantFiled: June 1, 2007Date of Patent: August 31, 2010Assignee: Honeywell International Inc.Inventors: Barrett E. Cole, James A. Cox, Daniel C. Hawkinson

Patent number: 7760359Abstract: A projected beam smoke detector includes circuitry and control software to measure a distance a beam travels between the detector's transmitter and receiver. Either a time-based or a phase-based measurement methodology could be used. A sensitivity parameter of the detector could be set in response to the results of the measurement.Type: GrantFiled: December 10, 2007Date of Patent: July 20, 2010Assignee: Honeywell International Inc.Inventors: Daniel C. Hawkinson, Robert J. Clow

Patent number: 7061392Abstract: An exit path indicating device incorporates at least a first port for receiving an alarm indicating signal. In normal operation upon receipt of the alarm indicating signal, the device outputs a visual or an audible, or both, indicator of the presence of an exit or egress path for use in evacuating the region. A second port disables the operation of the device. The second port can be coupled to a local sensor which provides an indication of a hazardous or alarm condition adjacent to or on the exit or egress path. If the sensor is indicating the presence of a hazardous or alarm condition, the indicating device can be disabled.Type: GrantFiled: December 12, 2003Date of Patent: June 13, 2006Assignee: Honeywell International, Inc.Inventor: Daniel C. Hawkinson

Patent number: 6577232Abstract: A communication protocol facilitates transmission at maximum rates for various types of cables. The protocol can be used to transmit information between a common control unit and a plurality of spaced apart devices coupled thereto. Alternately, the protocol can be used for transmission of information between devices. One control unit or device transmits clock pulses, while in a low impedance state. The devices respond to the clock pulses and transmit data on the communications link, in a low impedance state, when the source of clock pulses assumes a high impedance state. One or more features of transmitted signals can be used to implement one or more synchronized functions.Type: GrantFiled: October 31, 2000Date of Patent: June 10, 2003Assignee: Pittway CorporationInventors: Daniel C. Hawkinson, Mark C. Bohannon, David C. Doll, Robert J. Clow

Patent number: 6462653Abstract: An event detection system has a control element coupled to a plurality of detectors, such as smoke detectors. The control element can be implemented with a programmed processor. The detectors can include a base which removably receives a separable detector housing and electronics. Group boundaries can be specified by incorporating boundary defining electrical elements, such as switches or resistors, into either a respective detector base or into the detector itself. The control element can include instructions for carrying out an automatic addressing process with respect to the detectors. Topology information obtained during the automatic addressing process in combination with the location of the boundary defining elements specifies one or more groups for the control element. In an alternate embodiment, groups can be defined based exclusively on the topology information. In this embodiment, boundary defining electrical elements are not needed.Type: GrantFiled: December 13, 1999Date of Patent: October 8, 2002Assignee: Pittway CorporationInventors: Steven L. Scorfield, Daniel C. Hawkinson, Mark C. Bohanon

Patent number: 6366215Abstract: The members of a multi-processor communication system can be loaded with a common set of control programs. Subsequently, the functionality of the various processors can be specified by providing linking information to the respective processors. The linking information specifies which control programs, in which order, are to be executed by a respective processor. Processors can be associated with or bound to a respective system using encrypted control codes. The functional integrity of one or more modules at a respective processor can be verified.Type: GrantFiled: December 4, 1998Date of Patent: April 2, 2002Assignee: Pittway CorporationInventors: Lee D. Tice, Steven W. McCuen, Edward J. Kurtz, Daniel C. Hawkinson
