Patent number: 7890301Abstract: Representative embodiments are directed to distributed sensor systems from which measurement data is extracted using mobile devices. Representative embodiments record access attempts by the mobile devices and calculate the probabilities of future access by a mobile device to sensor devices using the recorded information. Collection points are selected in response to the probabilities of future access. Additionally, memory management and data prioritization may occur that is at least partially dependent upon the probabilities of future access.Type: GrantFiled: June 24, 2004Date of Patent: February 15, 2011Assignee: Agilent Technologies, Inc.Inventors: Jogesh Warrior, John C.

Patent number: 7242294Abstract: A system and method are provided that use mobile collectors for accessing a wireless sensor network. In certain embodiments, one or more mobile collectors having mobility that is unpredictable to a wireless sensor network are deployed for use in accessing the wireless sensor network. Thus, rather than relying on an access technique having certainty designed therein with regard to the access of a wireless sensor network, certain embodiments utilize an access technique that relies on statistical probability for accessing the wireless sensor network. For instance, by deploying a plurality of mobile collectors that are operable for accessing a wireless sensor network, a statistical probability exists that at some point (or at various points in time) at least one of the mobile collectors will travel within range of the wireless sensor network to enable access thereof.Type: GrantFiled: September 17, 2003Date of Patent: July 10, 2007Assignee: Agilent Technologies, IncInventors: Jogesh Warrior, John C.

Publication number: 20050216227Abstract: Embodiments of the present invention are directed to sensor nets from which data is extracted using mobile devices. Sensor devices within the sensor nets record access attempts by mobile devices. Using the recorded access attempts, the probabilities of future access to respective sensor devices are calculated. Collection points are selected using the calculated probabilities. Also, the probabilities of future access are distributed through the sensor nets. Routing of measurement data within the sensor nets may occur using the calculated probabilities.Type: ApplicationFiled: March 23, 2004Publication date: September 29, 2005Inventors: Jogesh Warrior, John Eidson, Jerry Liu

Publication number: 20040233069Abstract: A wireless device displays a view of location data to a user. The location data includes readily recognizable features in a geographical area, such as a geographical map or a list of cities, neighborhoods, businesses, intersections, streets, or landmarks. A user selects a particular location data from the view and the selected location data is displayed in more detail. The process of selecting particular location data and displaying that location data in more detail continues until a location can be specified from the displayed view.Type: ApplicationFiled: June 28, 2004Publication date: November 25, 2004Inventors: Jogesh Warrior, Jerry J.

Patent number: 6654356Abstract: A distributed system with an architecture based on synchronized clocks that provides accurate coordination of control functions. The distributed system includes a set of nodes coupled to a communication link. Each node has a clock which holds a real-world time. The nodes participate in a synchronization protocol on the communication link for synchronizing the real-world time in each clock. The architecture of the distributed system is such that the synchronization of control functionality in the distributed system is based upon the real-world time in the clocks. A variety of examples of applications for this architecture are set forth.Type: GrantFiled: October 29, 1998Date of Patent: November 25, 2003Assignee: Agilent Technologies, Inc.Inventors: John C.

Patent number: 5960375Abstract: A circuit for compensating variables in a measurement transmitter. Within the transmitter, a sensor senses a primary process variable such as differential pressure and a converter digitizes the sensed process variable. The sensor senses pressures within a span of pressures values. A memory inside the transmitter stores at least two membership functions, each membership function having a non-zero value over a predetermined region of the process variable span and a substantially zero value over the remainder of the span. The memory also stores a set of compensation formulas, each formula corresponding to a membership function. A selection circuit in the transmitter selects those membership functions which have a non-zero value at the digitized process variable and a correction circuit provides at least one correction value, each correction value calculated from a compensation formula corresponding to a selected membership function.Type: GrantFiled: May 30, 1997Date of Patent: September 28, 1999Assignee: Rosemount Inc.Inventors: Jogesh Warrior, Scott E.

Patent number: 5825664Abstract: A smart field-mounted control unit, for controlling a process, receives signals and sends a command output over a two-wire circuit which powers the control unit. An input section receives the signals, which can be instructions representative of commands or instruction sets, process variables sensed by external control units or setpoints representative of a desired process state. The instructions are representative of a control requirement of the process and adjust a controlling section in the control unit to generate the command output in conformance with the control requirement. The command output can be a function of the difference between the process setpoint and a process variable, or a function of a linear combination of a process variable and its calculated time integral and time derivative functions. A sensing section in the control unit can sense and scale a process variable for generating the command output as well.Type: GrantFiled: June 7, 1995Date of Patent: October 20, 1998Assignee: Rosemount Inc.Inventors: Jogesh Warrior, Vincent C.
