Patent number: 10750420Abstract: Provided are methods and systems of managing vertical handoffs in a wireless communication network. Embodiments include analyzing wireless device usage to determine usage patterns, which may include locations and times at which the wireless device is typically accessing the network. The network may recognize points in the usage patterns at which signal quality parameters are typically reduced. Such reductions in signal quality parameters may lead to inefficient vertical handoffs. The network may decrease adverse effects of inefficient vertical handoffs by reducing ping ponging, selecting links between wireless devices and network nodes, or indicating to a user of the wireless device that delays and/or data loss may occur.Type: GrantFiled: August 6, 2018Date of Patent: August 18, 2020Assignee: General Electric CompanyInventors: John Erik Hershey, John Anderson Fergus Ross, Michael James Hartman, Richard Louis Zinser

Patent number: 10666623Abstract: Provided are methods and systems of using division-free duplexing (DFD) in a cable communication network. Techniques for applying DFD in a cable communication network may enable data to be transmitted and received over a coaxial cable without using division duplexing techniques. For example, the cable communication network may include DFD enabled network nodes and each subscriber to the cable network may be equipped with a DFD system configured to operate in a DFD mode. In some embodiments, oppositely propagating signals may be transmitted over one frequency channel, and DFD techniques may be used to recover originally transmitted signals. Further, in some embodiments, DFD techniques may be used with encryption methods to increase the security of data transmitted in the cable communication network.Type: GrantFiled: June 9, 2014Date of Patent: May 26, 2020Assignee: General Electric CompanyInventors: John Anderson Fergus Ross, Michael James Hartman, John Erik Hershey, Richard Louis Zinser

Patent number: 9727671Abstract: In an example embodiment, a method of calculating end-of-life (EOL) predictions for a physical asset is provided. A state-space model for the physical asset is obtained, the state-space model being a physics-based model describing a state of the physical asset at a particular time given measurements or observations for the physical asset. Then a current state of the physical asset is inferred. Then a long-term prediction is derived for the physical asset based on the inferred current state of the physical asset and the state-space model for the physical asset. Then an EOL probability distribution function is generated for the physical asset based on the long-term prediction, the EOL probability distribution function describing a range of estimates of EOL for the physical asset and their corresponding confidence intervals.Type: GrantFiled: February 26, 2015Date of Patent: August 8, 2017Assignee: General Electric CompanyInventors: Satish Giridhar Iyengar, John Anderson Fergus Ross, Frederick Wilson Wheeler, Naresh Sundaram Iyer, Paulo Ricardo dos Santos Mendonca, Ashok Sundaresan, Yujiao Zheng

Patent number: 9369260Abstract: Provided are methods and systems of using division-free duplexing (DFD) in a communication network. Techniques for applying DFD in a communication network may decrease bottlenecks in the network by allowing one or more network nodes to transmit and on substantially the same frequency and at substantially the same time. In one embodiment, one or more nodes in the network may be DFD enabled, and may be configured to operate in either a conventional mode or a DFD mode. The mode of operation of DFD enabled nodes may depend on the quality of signals transmitted to and/or received at the DFD enabled nodes. Further, the mode of operation may change dynamically, and may be substantially controlled by any suitable processor in the network.Type: GrantFiled: April 9, 2010Date of Patent: June 14, 2016Assignee: General Electric CompanyInventors: John Anderson Fergus Ross, Michael James Hartman, John Erik Hershey, Richard Louis Zinser

Patent number: 9355670Abstract: Techniques are provided for increasing spectral efficiency over data channels in a storage or communication system. In some embodiments, data may be encoded and transmitted over multiple channels. The transmitted data from the multiple channels may be considered together as a channel bundle, thereby increasing the edge transitions of the group of signals to improve clock recovery and reduce coding constraints. In some embodiments, the channel bit size is reduced to maximize data rates based on the reduced coding constraints. Furthermore, the channel bundle has only one channel with timing markers, so that a receiver may receive information from the channel bundle and recover clocking based on the timing markers in the one channel.Type: GrantFiled: April 7, 2015Date of Patent: May 31, 2016Assignee: General Electric CompanyInventors: John Anderson Fergus Ross, Michael James Hartman, John Erik Hershey, Richard Louis Zinser, Xiaolei Shi

Patent number: 9318145Abstract: The present techniques provide systems and methods for decoding an optical data signal in an optical system to retrieve source information while decreasing errors resulting from optical and electronic noise in the optical system. The techniques involve using decoding algorithms to estimate the a posteriori state probabilities and the a posteriori transition probabilities of the data encoding, and estimating bit state probabilities. The probability density function used to estimate bit states is parameterized by the expected optical and electronic noise in the optical system. Different optical and electronic noise variances, or different probability densities, may be stored in registers or look-up tables to be accessed by a decoder while decoding the optical data signal.Type: GrantFiled: March 30, 2009Date of Patent: April 19, 2016Assignee: General Electric CompanyInventors: Aria Pezeshk, John Anderson Fergus Ross

Patent number: 8891343Abstract: The present techniques present methods and systems for increasing a data reading rate on optical data disks using a single reading head. The methods take advantage of the difference between a mean focal distance (MFD), or minimum spacing that the detector can distinguish between bits, and the minimum separation of bits in a single track to increase the reading speed. As the bits may be more closely spaced across adjacent tracks or layers, these techniques may be used to increase the reading speed of the disk. Specifically, the data symbols that make up a single bit-stream may be stored in a pattern horizontally across adjacent tracks, or vertically across adjacent layers. Accordingly, the focal point of the detector is scanned across the disk in the same pattern to read the individual data symbols.Type: GrantFiled: December 17, 2008Date of Patent: November 18, 2014Assignee: General Electric CorporationInventors: John Anderson Fergus Ross, Kenneth Brakeley Welles, John Erik Hershey, Brian Lee Lawrence, Xiaolei Shi, Victor Petrovich Ostroverkhov
