  • Patent number: 9630510
    Abstract: In one embodiment, an engine management system (EMS) can use a human machine interface (HMI) to modify operating parameters of a set of engine generators controlled by an engine control unit (ECU). The HMI can permit authorized users to adjust a plurality of operating parameters of the engine generators in accordance with an authorization level of the authorized users. The ECU can be a standalone system operable independent of the EMS. A communication network (e.g., ARCnet) can link the EMS to the ECU, wherein the changes of the operating parameters input via the HMI are maintained over a power-cycle of the EMS. Further, changes of the operating parameters input via the HMI can be maintained even when communications over the communication network linking the engine.

  • Patent number: 9634576
    Abstract: A power conversion system includes at least one multi-level power converter and a controller coupled to the at least one multi-level power converter. The controller includes a first CMV injection module and a second CMV injection module. The first CMV injection module generates a first CMV signal for modifying at least one voltage command to achieve a first function in association with operation of the power conversion system. The second CMV injection module generates a second CMV signal based at least in part on a local limit either for modifying the at least one voltage command or for further modifying the at least one modified voltage command to achieve a second function in association with operation of the power conversion system.

  • Patent number: 9634549
    Abstract: A magnetic component having intermixed first and second regions, and a method of preparing that magnetic component are disclosed. The first region includes a magnetic phase and the second region includes a non-magnetic phase. The method includes mechanically masking pre-selected sections of a surface portion of the component by using a nitrogen stop-off material and heat-treating the component in a nitrogen-rich atmosphere at a temperature greater than about 900° C. Both the first and second regions are substantially free of carbon, or contain only limited amounts of carbon; and the second region includes greater than about 0.1 weight % of nitrogen.

  • Publication number: 20170105683
    Abstract: A cluster database includes existing, ECG datasets organized into clusters, wherein each existing ECG dataset includes an existing ECG waveform with at least one corresponding existing feature and existing interpretation. Each cluster is comprised of existing ECG datasets having a common existing feature. The duster training module is executable by the processor to receive a new ECG waveform and a feature extracted from the new ECG waveform. The cluster training module then selects a cluster interpretation module based on the feature, wherein the cluster interpretation module is trained on one of the clusters from the duster database. The duster training module processes the new ECG waveform and/or the feature to provide a duster interpretation output. The cluster interpretation output is then displayed on the user interface, and the cluster training module receives clinician input via the user interface accepting or rejecting the cluster interpretation output.

  • Publication number: 20170107812
    Abstract: A system and method are described which are useful for monitoring parameters of drilling fluid within a drilling system comprising a drilling assembly. The drilling assembly is connected between a drilling platform and a wellhead and is useful for more safely drilling a wellbore necessary for hydrocarbon exploration and production by signaling the occurrence of a kick. The drilling assembly comprises a reader module for reading data information of at least one RF tag dispersed in a returned drilling fluid. The data information of the RF tag is transmitted to a controller via a communication link to calculate related parameters of the returned drilling fluid. A method for monitoring parameters of drilling fluid, and an allied blowout preventer for a drilling system are also provided.

  • Publication number: 20170105678
    Abstract: A method of directing positioning of ECG electrodes on a patient includes receiving at a processor an image of the patient with one or more electrodes and determining with the processor an actual location of each of the electrodes on the patient based on the image. The method further includes determining with the processor whether the actual location of each of the electrodes is correct and providing information via a user interface regarding the actual location of the electrodes.
