Patent number: 8456285Abstract: A method for use in a power line communication systems for an electrical distribution system (1) to quickly and accurately poll electrical meters (6) installed at user facilities to determine if an outage has occurred at a facility. An outbound communications message is transmitted to the meter at the facility requesting a short response consisting of a bit pattern that is either partially or completely known to the receiver. Any perceived response from the meter is then processed to ascertain whether or not the meter actually transmitted a message. Receipt of a message indicates that an outage has not occurred at that site, while an indication the message was not received indicates an outage has likely occurred. In processing the received message, two types of errors can potentially occur; i.e., a false positive or a false negative.Type: GrantFiled: August 9, 2007Date of Patent: June 4, 2013Assignee: Aclara Power-Line Systems, Inc.Inventor: Quentin Spencer

Patent number: 8180547Abstract: In one embodiment, a system and method are provided for detecting a slip condition between a vehicle tire and a road surface, processing contemporaneous vehicle data, such as torque or brake pressure applied, to determine a force of friction, and calculating a coefficient of friction. The coefficient of friction and location of the slip are broadcast to other vehicles driving in the proximity of the slip. The broadcasts may be utilized to notify drivers of slippery driving conditions at or ahead of the vehicle, and/or to limit torque and braking pressure applied to vehicle wheels to enhance traction and avoid slip.Type: GrantFiled: March 27, 2009Date of Patent: May 15, 2012Assignee: Ford Global Technologies, LLCInventors: Krishnaswamy Venkatesh Prasad, Christoph Arndt, Thomas Joseph Hermann, David P Boll

Patent number: 7071838Abstract: A power supply controller has two control units for coupling to primary and secondary sides of controlled power supplies, the units being coupled via a transformer which couples signals between the units, a power supply voltage for the secondary-side unit being derived from signals coupled from the primary-side unit. Initially signals are coupled from the primary unit with an increasing duty cycle to charge a secondary-side power supply capacitor. Subsequently signals are coupled in signal frames in alternating directions between the units, each signal frame from each unit indicating whether or not signal frames are correctly received from the other control unit. The signal frames also provide for downloading information for the control units, and other status signals and commands and acknowledgements.Type: GrantFiled: May 2, 2003Date of Patent: July 4, 2006Assignee: Potentia Semiconductor, Inc.Inventors: David Alan Brown, Mircea Cristian Boros

Patent number: 6853310Abstract: A tri-mode telemetry system useful for monitoring patients in a care unit of a health care facility. The system includes an antenna system with a first antenna tuned to receive a signal in a first communication band, a second antenna tuned to receive a signal in a second communication band, a third antenna tuned to receive data signals, a down converter for producing a frequency translation signal, and a mixer coupled to the second antenna. The mixer combines the signal received by the second antenna with the frequency translation signal to produce a signal having a frequency in the first communication band. A combiner coupled to the mixer and the first antenna combines the signal generated by the mixer with the signal received by the first antenna. The combined signals and data signals are delivered to a wiring system.Type: GrantFiled: November 14, 2001Date of Patent: February 8, 2005Assignee: GE Medical Systems Information Technologies, Inc.Inventor: James W.

Patent number: 6401081Abstract: Conventional AMR and DA/DSM systems typically suffer from a lack of extensibility due to the monolithic nature of the master station software. In contrast, this patent describes a system that is comprised of small modules connected using a component object model. This system allows straightforward extension in the areas of applications, communications, metering devices, and databases without requiring recompilation or relinking of the system. Furthermore, this system allows commercial applications such as spreadsheets, word processors, statistical packages, report generators, et cetera to be integrated directly with this system, and allows extension and customization of the system using such packages. Such a flexible open architecture is very attractive to utilities in that it allows easy extension by the utility or other third party developers without the involvement of the original authors of the system.Type: GrantFiled: November 20, 1995Date of Patent: June 4, 2002Assignee: Schlumberger Resource Management Services, Inc.Inventors: Michael Andrew Montgomery, Lloyd Howard Strine, Susanne Kristina Marie Howard, Leor Amikam, Neil MacLean, Mark Alan Hastings
