Patent number: 8811231Abstract: Wireless communication systems using transmitter initiated communications methods. Several devices in the system listen by following a common frequency hopping sequence. When communication is desired, a transmitting device sends a request to send signal to an addressee; if available, the addressee sends a clear to send signal, and the transmitting device and the addressee then perform communications using a separate frequency hopping sequence. Methods for adding new devices are also included. In an example, a new device uses a discovery frequency hopping sequence to ping a number of frequencies until the common frequency hopping sequence is discovered. In another example, a new device listens on a single frequency forming part of the common frequency hopping sequence until the common frequency hopping sequence overlaps the single frequency.Type: GrantFiled: October 21, 2005Date of Patent: August 19, 2014Assignee: Honeywell International Inc.Inventors: Ramakrishna S.

Patent number: 8681676Abstract: A system, apparatuses, and methods support simultaneous connectivity between devices in an industrial control and automation or other system. For example, a data publisher can publish or provide data to multiple data subscribers. This can be done using a multicast group associated with the multiple data subscribers. The data publisher transmits a data message using a network address associated with the multicast group. Each data subscriber associated with the multicast group receives a copy of the data message. As a particular example, the data publisher could represent a wireless sensor or wireless actuator in the industrial control and automation or other system. Also, the data subscribers could represent multiple controllers or actuators in the industrial control and automation or other system. In this way, the multicasting functionality allows for simpler connectivity or interaction between devices in the industrial control and automation or other system.Type: GrantFiled: October 30, 2007Date of Patent: March 25, 2014Assignee: Honeywell International Inc.Inventors: Ramakrishna S.
