Sep 2, 2005

Appl. No.:

11/219248

Inventors:

John Bruce Stratton - Santa Rosa CA, US
Leon Kenneth Werenka - Mukilteo WA, US

International Classification:

G06F 13/36

US Classification:

710312000

Abstract:

A legacy interface module that enables legacy instruments to function in instrument systems based on synchronized time. A legacy instrument module according to the present teachings adapts a legacy interface of a legacy instrument to an instrument system based on synchronized time without modifications to the legacy instrument.

International Classification:

G08B 29/00

US Classification:

340506000

Abstract:

Sensors in a network each have a geographical location and they each periodically broadcast this information to all the sensors in the network. Each receiving sensors then builds a list of sensors (neighbor list) that are closest to that sensor by computing the distance between itself and the other sensors. This list can then be used along with a decision algorithm to decide whether that sensor should act or perform a command when it receives a message from other sensors. In one embodiment, a sensor can use the neighbor list to command a specific other sensor(s) to perform a specific function.

Abstract:

Timing information comprised of a network-based time synchronization protocol is exchanged over the network in order to synchronize a receiver clock in each RF receiver to a common network time. Each RF receiver generates a status parameter characterizing the synchronization of its receiver clock to the common network time when the receiver transmits a message over the network. A central processing device and each RF receiver that receives a message analyzes the status parameter to determine the synchronization status of the transmitting RF receiver.
