Patent number: 8350573Abstract: According to the features discussed herein, through a single generalized arc-fault detection algorithm, various types of series and/or parallel arc faults can be detected without any nuisance trip for either AC or DC Electric Power Systems. Running Discrete Fourier Series (RDFS) formulation for nuisance-free operation and cost-effective implementation is developed. Unlike other methods which require numerous source and load-side current and voltage measurements, only source side current is required. An arc detector may include a first detector to monitor variations of a magnitude of a fundamental component of a current, and a second detector to monitor an overload condition based in an i2t calculation.Type: GrantFiled: September 27, 2010Date of Patent: January 8, 2013Assignee: Honeywell International Inc.Inventors: Hassan Ali Kojori, Yang Ye

Patent number: 8352470Abstract: A method for use with an aggregation operation (e.g., on a relational database table) includes a sorting pass and a merging pass. The sorting pass includes: (a) reading blocks of the table from a storage medium into a memory using an aggregation method until the memory is substantially full or until all the data have been read into the memory; (b) determining a number k of blocks to write back to the storage medium from the memory; (c) selecting k blocks from memory, sorting the k blocks, and then writing the k blocks back to the storage medium as a new sublist; and (d) repeating steps (a), (b), and (c) for any unprocessed tuples in the database table. The merging pass includes: merging all the sublists to form an aggregation result using a merge-sort algorithm.Type: GrantFiled: May 23, 2008Date of Patent: January 8, 2013Assignee: International Business Machines CorporationInventors: Ying Chen, Bin He

Patent number: 8344545Abstract: An electrical power distribution system for a vehicle may provide from alternate sources of power to an electrical load. Two solid state power contactors (SSPC's) may provide connectivity paths between two power sources and the equipment. The SSPC's may be interconnected so that power to the load is provided on a first connectivity path between a first source of power and the load, unless and until a power interruption occurs on the first path. In the event of power interruption, the SSPC's actuate a second connectivity path between a second source of power and the load. Transfer of power sources may occur in a time period that is less than an equipment transparency time of the load.Type: GrantFiled: January 20, 2009Date of Patent: January 1, 2013Assignee: Honeywell International Inc.Inventors: Randy Fuller, Ted Gayowsky, David Lazarovich

Patent number: 8328606Abstract: An altitude switch limit assembly has two independent limit switches to monitor cabin pressure and back up performance of the auto and monitor channels on the aircraft. The auto channel closes a first switch upon sensing that a cabin pressure falls below a set value, the monitor channel closes a second switch upon sensing that the cabin pressure falls below the set value. A first independent limit switch may be wired to the auto channel and a second independent limit switch may be wired to the monitor channel. Logic circuitry may determine that the assembly closes an outflow valve regulating cabin pressure when either both independent limit switches sense the condition, or when one of the independent limit switch senses the condition and either the auto channel or monitor channel to which that independent limit switch may be wired senses the same condition.Type: GrantFiled: March 10, 2009Date of Patent: December 11, 2012Assignee: Honeywell International Inc.Inventors: Ed Benkert, Rich Morey, Duane Inscho

Patent number: 8327924Abstract: A heat exchanger fin capable of increasing convective heat transfer by reducing internal conduction along an undesirable direction within the heat exchanger fin itself is disclosed. More specifically, the current invention reduces conduction within the heat exchanger fin along an undesirable direction along the direction of fluid flow because such conduction decreases the performance of the heat exchanger fin. A heat exchanger fin in accordance with the present invention utilizes a plurality of notches within the heat exchanger fin that is perpendicular to the direction of fluid flow to increase the resistance of conduction within the heat exchanger fin itself. By increasing the resistance of conduction in an undesired direction, the heat exchanger fin is capable of more uniform temperature to along the entire surface area to facilitate increase convective heat transfer in the desired direction.Type: GrantFiled: July 3, 2008Date of Patent: December 11, 2012Assignee: Honeywell International Inc.Inventors: Arun Muley, Joe Borghese, Michael Williams

Patent number: 8332955Abstract: A method for carrying out a secure transaction in a 3D virtual space is desired from both an administrator side operating a facility and a user side. It is also desired to solve the problems such as the confidentiality of a transaction in the 3D virtual space and a phishing scam. In the present invention, a copy space of an original space of a facility in the 3D virtual space is created. Since only avatars permitted to enter the copy space can enter the copy space, a secure transaction can be carried out between the facility and a user avatar.Type: GrantFiled: August 25, 2008Date of Patent: December 11, 2012Assignee: International Business Machines CorporationInventor: Shinya Kawanaka

Patent number: 8324906Abstract: Hidden or overlapped peaks may occur when using SSTDR technology to determine ware faults. These hidden/overlapped peaks may cause false negative determinations (no fault) when testing a wire for faults. In one method of the present invention, the symmetrical property of the SSTDR wave envelope is used to resolve hidden/overlapped peaks. In another method of the present invention, the calibrated normalized loop back SSTDR wave envelope may be used to resolve hidden/overlapped peaks.Type: GrantFiled: March 19, 2010Date of Patent: December 4, 2012Assignee: Honeywell International Inc.Inventors: Shaik Shafi Ahamed, Srinivasa Rao Dangeti, Narasimha Rao Pesala, Thappeta Peddaiah, Sreenivasulu Reddy Vedicherla, Vedagiribabu Subramanyam, Zhenning Liu

Patent number: 8321396Abstract: A by-line extraction system detects a set of potential headlines from a title meta-tag of a crawled document, selects a candidate headline from the set of potential headlines, and extracts the by-line information from the document using the location of the selected candidate headline. The system constructs the set of potential headlines based on the title meta-tag. The system selects a candidate headline by evaluating the set of potential headlines in order of the lengths of the potential headlines. The system extracts the by-line information from the document by using the location of the selected candidate headline to extract a string representing a date, a name, or a source located within a minimum distance from the location of the potential headline.Type: GrantFiled: August 15, 2008Date of Patent: November 27, 2012Assignee: International Business Machines CorporationInventors: Stephen Dill, Madhukar R.
