Process Field Instrument With Integrated Sensor Unit And Related System And Method
US Patent:
2009010, Apr 30, 2009
Filed:
Oct 30, 2007
Appl. No.:
11/981194
Inventors:
Jeffrey M. Becker - Scottsdale AZ, US
Assignee:
Honeywell International Inc. - Morristown NJ
International Classification:
G01N 1/22
US Classification:
73 232
Abstract:
A sensor is integrated with a field instrument in a process control system. For example, the sensor can be at least partially housed in a housing of the field instrument. The sensor could also receive operating power from a power source in the field instrument. The sensor could further communicate using a wired interface and/or a wireless interface of the field instrument. Multiplexing techniques could be used to allow normal communications for the field instrument and information associated with the sensor. For instance, field instrument data and sensor data could be transmitted over different interfaces or multiplexed in time for communication over a single interface. Sensor data could also be included as at least one diagnostic or configuration variable along with the field instrument data. The field instrument could represent a gas meter associated with a gas distribution network, and the sensor could represent a gas sensor.
System And Method For Providing Self-Locating Wireless Sensors
US Patent:
2010002, Feb 4, 2010
Filed:
Jul 31, 2008
Appl. No.:
12/183263
Inventors:
Jeffrey M. Becker - Scottsdale AZ, US
Assignee:
Honeywell International Inc. - Morristown NJ
International Classification:
G08B 5/22
US Classification:
34082549
Abstract:
A wireless sensor network is disclosed that comprises a plurality of wireless sensors and a wireless sensor base station. The wireless sensor base station sends a request to one of the wireless sensors requesting the location information for the selected wireless sensor. The wireless sensor determines its location using a location information determination method, associates its identity information with the location information, and sends the identity information and the location information to the wireless sensor base station. The wireless sensor continuously sends updated location information to the wireless sensor base station as the wireless sensor moves within the wireless sensor network. The wireless sensor base station displays the identity information and the location information of the wireless sensor on a display unit.
Apparatus And Method For Providing A Failsafe-Enabled Wireless Device
A method for operating a failsafe-enabled wireless device is provided that includes monitoring a signal quality for a wireless signal between a failsafe-enabled wireless device and a controller. A determination is made regarding whether the signal quality is poor. A failsafe procedure is initiated when the signal quality is poor.
