Patent number: 10679131Abstract: Endpoint device, central data collection point, and associated methods for collecting data over a communication network between endpoints and the central collection point. Actual measurements from a sensor are obtained by the endpoint device at a relatively fine time granularity. The endpoint device generates reports for receipt by a central data collection point. The reports include regular reports containing a portion of the actual measurements representing sensor measurements at a relatively coarse time granularity, and exception reports, containing information representing one or more of the actual measurements that differ in frequency or granularity of regular report measurements. Each of the exception reports is generated in response to a determination that at least one of the actual measurements differs from a predicted value for that at least one of the one or more actual measurements by an amount that exceeds a pre-established limit.Type: GrantFiled: July 12, 2012Date of Patent: June 9, 2020Assignee: Eaton Intelligent Power LimitedInventor: Roger K.

Patent number: 10278113Abstract: In a self-organizing wireless multihop network, each node device selects operation among short-range (SR) and long-range (LR) communication modes, among which the SR mode uses a higher data rate than the LR mode. Each node device advertises connectivity link availability for neighboring node devices, and selectively initiates a link in response to connectivity availability advertised by at least one neighboring node device. The availability advertising is performed in the SR and the LR communication modes, according to a periodicity that is dynamically-variable in response to prevailing circumstances in the local neighborhood. The link initiation is selectively performed in one of either the SR or the LR communication mode based on selection criteria that include data throughput performance associated with different neighboring node devices with which connectivity is available via a certain communication mode.Type: GrantFiled: June 27, 2017Date of Patent: April 30, 2019Assignee: Eaton Intelligent Power LimitedInventors: Roger K.

Patent number: 10222232Abstract: A sensor data collection system includes a plurality of sensors operatively coupled to a corresponding set of endpoints, the endpoints configured to communicate sensor data to a central data collection point via a data communication protocol. A proxy service-enabled endpoint facilitates interoperability with the data collection system for the benefit of endpoints that are otherwise incompatible with the data communication protocol. The endpoint includes a remote endpoint interface module configured to receive communications from at least one of the incompatible endpoints containing incompatible endpoint sensor data. A remote endpoint virtualization module operatively coupled to the remote endpoint interface module and associated with the at least one of the incompatible endpoints.Type: GrantFiled: May 9, 2017Date of Patent: March 5, 2019Assignee: Eaton Intelligent Power LimitedInventor: Roger K.

Technique for least cost routing for mobile satellite systems employing a GSM network infrastructure
Patent number: 6067452Abstract: A system and method for achieving least cost call routing (i.e., shortest terrestrial path between mobile terminal and a fixed terminal) for a mobile communications system by integrating a cellular satellite communications system with an existing GSM network to form an extended satellite GSM system and an enhanced satellite GSM system. The extended satellite GSM system incorporates the advantages facilitated by the GSM network with the extended coverage capability of the mobile satellites, and achieves least cost call routing by registering a mobile terminal with one designated gateway (i.e., home gateway). In accordance with another embodiment, the enhanced satellite GSM system achieves least cost call routing for all mobile terminal originated and terminated calls by minor modifications to the mobile terminal and home location register.Type: GrantFiled: May 28, 1996Date of Patent: May 23, 2000Assignee: Comsat CorporationInventor: Roger K.
