Patent number: 7126494Abstract: An electronic meter incorporates a TCP/IP protocol suite and an HTTP server to provide two-way access to the meter data. Alternatively, the TCP/IP protocol suite may be incorporated into a gateway serving multiple meters connected through a power line or wireless two-way network. The gateway may incorporate an HTTP server for accessing data from multiple meters and for transmission of data to individual meters. Other aspects of the disclosed system include the use of a common gateway interface for remote access to meter data and to set meter parameters using HTML forms in HTTP browsers; remote reading and setting of multiple meter parameters using a TCP/IP protocol suite; a TCP/IP protocol suite implemented in designated nodes in a CEBus LAN with remote access through TCP/IP to routers and brouters and to individual meters on the LAN; and an SLIP-PPP enabled gateway for remote TCP/IP access through a serial interface to a single or multiple meter parameters.Type: GrantFiled: June 7, 2004Date of Patent: October 24, 2006Assignee: Elster Electricity, LLCInventors: Sasan H. Ardalan, David E. Van den Bout

Patent number: 6900737Abstract: An automatic meter reading (AMR) system collects readings from multiple or individual meters or sets parameters in individual or multiple meters using the Short Message Service (SMS) in digital cellular networks. The individual meters incorporate interfaces to the SMS network so that parameters within the meter can be read and written to/from external devices that also interface to the SMS network. Communications gateways incorporate a single interface to the SMS network, which a set of non-SMS-enabled meters can access via a local area network (LAN).Type: GrantFiled: February 12, 1998Date of Patent: May 31, 2005Assignee: Elster Electricity, LLCInventors: Sasan H. Ardalan, David E. Van Den Bout, Arnold W. Bragg

Patent number: 6867707Abstract: The invention is directed to a method and system for verifying an installation of an meter, for example, an electric power meter. The inventive method includes identifying the electric power meter to a central computer using a mobile computing device. The electric power meter receives computer-executable instructions from the central computer via the mobile computing device, and transmits meter information (e.g., power consumption readings, meter identification information, and meter location) to the central computer. The meter information received from the central computer is compared with meter information available at the electric power meter. The comparison may be accomplished visually by reading the meter and comparing the readings with the information received on the mobile computing device. Also, the comparison may be accomplished automatically by the mobile computing device based on the information it receives from the central computer and the information it receives from the electric power meter.Type: GrantFiled: April 24, 2002Date of Patent: March 15, 2005Assignee: Elster Electricity, LLCInventors: Raymond H Kelley, John C. Sutton, III, Donna L. Bruce, Sasan H. Ardalan

Patent number: 6633900Abstract: A system for multi-crew management comprises an enterprise computing system, a mobile field unit, and wireless communication network which supports terminal control protocol/internet protocol (TCP/IP). The enterprise computing network comprises application programs through which work orders may be assigned and managed, various server machines containing data related to the work orders, a local area network (LAN) connecting the server machines, and a gateway to the TCP/IP wireless network. A mobile field unit comprises a computing device and modem for communicating over the wireless network to the enterprise computing system. A mobile field unit and each machine in the enterprise computing system has a unique IP address assigned to it. Accordingly, commands and data can be communicated freely between all machines.Type: GrantFiled: April 26, 2000Date of Patent: October 14, 2003Assignee: ABB Inc.Inventors: Amir Khalessi, Sasan H.

Patent number: 4677668Abstract: A parametric echo canceller comprising two transversal filters is employed to recursively model the echo path. The first transversal filter receives the input signal, the fed-back echo residual signal and a first set of Kalman gain coefficients to produce a first intermediate result. The second transversal filter receives the echo signal, the fed-back echo residual signal and a second set of Kalman gain coefficients to produce a second intermediate result. The second intermediate result is subtracted from the first to yield an estimated echo replica. The estimated echo replica is then subtracted from the echo to yield an echo residual. The taps of the first and second transversal filters are weighted in accordance with first and second sets of weighting coefficients, which are generated in accordance with the Fast Kalman Algorithm.Type: GrantFiled: May 1, 1984Date of Patent: June 30, 1987Assignee: North Carolina State UniversityInventors: Sasan H.
