Appl. No.:

11/939562

Inventors:

Anthony Paul Bata - Denver CO, US
Kenneth Ray Crismon - Bennett CO, US
David Kramer - Westminster CO, US
Randy Lyle Engle - Colorado Springs CO, US

Assignee:

Raytheon Company - Waltham MA

International Classification:

G08C 17/00

US Classification:

370311, 370340, 370310, 370338

Abstract:

A meshing network comprising one full function controller (WDC) and a plurality of nodes (WDN, WSN), that is RF quiet capable with very low power consumption and the ability to quickly heal itself and create new network paths. The network uses an addressing scheme that allows for each node to not have a network map but still be able to route messages. A piping scheme allows a mesh to become a high throughput network. A sensor rail protocol definition allows sensor devices to connect to nodes and route messages through the network.

Abstract:

A wireless mesh network with dynamic back off for reduced power consumption is generally described herein. In some embodiments, the wireless mesh network includes a network controller to configure a data frame comprising a sync period followed by at least one data period and a plurality of network nodes configured to operate in at least one of a network-running mode and a sleep/RF quiet mode. The network controller is configured to transmit synchronization messages during a first portion of the sync period and receive upstream requests from the network nodes during a second portion of the sync period. During the sleep/RF quiet mode, the network nodes are configured to wake up periodically during a listening interval for detection of a synchronization message from the network controller, and return to the sleep/RF quiet mode and increase a back-off time between listening intervals for increasingly longer periods when no synchronization message is detected.

Abstract:

Described are systems and methods to provide agnostic sensor data obtained from a sensor and transmitted to a central database by a transmitter device. In one aspect, a value sensed by a sensor component is converted at the transmitter device to an agnostic value defined by a dimensionless universal scale and offset. The agnostic value is then sent to a data acquisition database where it is converted back to the original value. This is accomplished by first providing the data acquisition database with a sensor definition of a scale and offset used to convert the sensor values in addition to any sensor indicia and other parameters to display the data acquired at the data acquisition database. The wireless sensors database and user interface are also automatically updated when a new sensor type is attached to the network utilizing configuration data that resides in the new sensor that is sent to the database on its first connection.

International Classification:

G06K 7/10

Abstract:

An RFID apparatus is disclosed generally comprising an RFID reader antenna attached to a microprocessor, the RFID reader antenna adapted to receive a first digital signal from a first RFID sensor and a second digital signal from a second RFID sensor. The RFID apparatus further possesses a converter that converts the first digital signal to a first analog output, such as electrical current, and the second digital signal to a second analog output. The apparatus can further possess a first electrical wire adapted carry the first analog output to a control system when the first electrical wire is connected to the control system. Also the apparatus can possess a second electrical wire adapted to carry the second analog output to the control system when the second electrical wire is connected to the control system. The control system is external to RFID apparatus and independent of the RFID apparatus.
