20120043922 | Variable Freqency Drive with Dielectric Fluid-Immersed Transformer - A variable frequency drive system for controlling the frequency of a high-voltage power source supplied to a first electric motor includes a transformer section that includes a motorized loadbreak switch system, control power transformers, a controller programmed with control logic to ensure that the motorized loadbreak switch system opens contacts between the high-voltage power source and the variable frequency drive system once the power source is removed, and a tank containing a dielectric fluid, wherein the tank also contains, within the dielectric fluid, a manual isolation switch to supply or remove power to the transformer section, an impedance for use in soft-starting the variable frequency drive system, a primary winding, and a plurality of phase-shifted secondary windings. | 02-23-2012 |
20120182089 | Passive Harmonic Filter for Power Distribution Systems - A subsea power distribution system includes a three-phase AC power source; multiple variable frequency drives having inputs and outputs, with their inputs connected to the AC power source; an electric motor connected in series to the output of each variable frequency drive; and a passive harmonic filter system having its input connected, in parallel with the variable frequency drives, to the AC power source. The filter system includes multiple harmonic filters, each harmonic filter tuned to a specific harmonic frequency. Each harmonic filter includes a plurality of sub-filters. Each sub-filter includes a reactor connected in series to a main capacitor and one or more detuning capacitors. Each of the multiple harmonic filters is tuned to a different specific harmonic, and includes sub-filters also tuned to the same respective harmonic, and each sub-filter is sized to equally share the kVAR load of its respective harmonic filter. | 07-19-2012 |
20150241881 | SUBMERSIBLE PUMP CONTROL - A system can include an interface to receive sensed data and economic data; a production control framework that includes a module for modeling motor efficiency of an electric submersible pump, a module for modeling gas composition of a fluid being pumped by an electric submersible pump, a module for modeling solid dynamics in a fluid being pumped by an electric submersible pump, a module to update one or more of the modules for modeling in response to receipt of data via the interface; and an interface to output control commands to a controller for an electric submersible pump based at least in part on data received by the interface and analyzed by the production control framework. Various other apparatuses, systems, methods, etc., are also disclosed. | 08-27-2015 |

20130297504 | TRANSACTION DATA TOKENIZATION - A system and method of tokenizing sensitive cardholder payment information for use in cashless transactions includes receiving a request to process a cashless transaction between a merchant and a purchaser using first payment data stored with an electronic wallet provider on behalf of the purchaser. First payment data is retrieved from the electronic wallet provider. The first payment data is tokenized into a payment token, and provided to the merchant for use in completing the cashless transaction. The merchant issues a request to process payment for the cashless transaction using the payment token. The payment token is detokenized into second payment data, with correspondence between the first and second payment data being indicative of payment token authenticity. Payment for the cashless transaction is processed using the second payment data, and the merchant is provided with a response indicating either the success or failure of the payment processing. | 11-07-2013 |

20110050360 | WIDEBAND ELECTROMAGNETIC CLOAKING SYSTEMS - Arrangement of resonators in an aperiodic configurations are described, which can be used for electromagnetic cloaking of objects. The overall assembly of resonators, as structures, do not all repeat periodically and at least some of the resonators are spaced such that their phase centers are separated by more than a wavelength. The arrangements can include resonators of several different sizes and/or geometries arranged so that each size or geometry corresponds to a moderate or high “Q” response that resonates within a specific frequency range, and that arrangement within that specific grouping of akin elements is periodic in the overall structure. The relative spacing and arrangement of groupings can be defined by self similarity and origin symmetry. Fractal based scatters are described. Further described are bondary condition layer structures that can activate and deactive cloaking/lensing structures. | 03-03-2011 |
