20080211455 | Rechargeable Power Supply, Battery Device, Contactless Charger System And Method For Charging Rechargeable Battery Cell - A system, method and apparatus for contact-less charging of battery operated devices is presented. There is a host charger with a power converter and resonant tank circuit and a portable device where the battery is located, with a battery charging control IC. The method obviates the need for a voltage controller in each of both the host and the portable stages, thus decreasing complexity and increasing efficiency. The charging of the battery in the portable device is controlled by a charging controller therein, which is in continual electric communication with the host, whose output power the control IC dynamically monitors and controls. Two embodiments for the charging circuitry in the portable device are presented. In one embodiment component count is minimized but battery charging is not optimized when the battery voltage is very low. In the other embodiment charging efficiency is maximized regardless of the output voltage of the battery, but additional components are utilized. | 09-04-2008 |
20080303479 | Contact-Less Chargeable Battery and Charging Device, Battery Charging Set, and Charging Control Method Thereof - The present invention relates to a wireless charger for a mobile communication terminal, which allows charging a plurality of batteries in a conveniently way without any terminal connection of the batteries to chargers for various mobile communication terminals such as a cellular phone and PDA and also allows intercepting electromagnetic waves while the charger is used, by means of Faraday's law. | 12-11-2008 |
20090102419 | WIRELESS CHARGER DECREASED IN VARIATION OF CHARGING EFFICIENCY - A wireless charger charges a storage battery of a portable electronic device in a wireless manner (non-contacting or contact-less) so that a variation of charging efficiency is not serious though the storage battery is placed any position of the wireless charger. The wireless charger is provided with a primary coil for generating a magnetic field so as to charge a subject, which is provided with a secondary coil, by means of inductive coupling with the secondary coil. The primary coil includes an outer coil arranged with a predetermined winding number and a predetermined size; and at least one inner coil arranged to be included inside the outer coil. The outer coil and the inner coil are arranged so that, when a primary current is applied to the outer coil and the inner coil, magnetic fluxes generated in the outer coil and the inner coil are formed in the same direction. | 04-23-2009 |

20140172382 | Pipeline Network Optimization Using Risk Based Well Production - Systems and methods for pipeline network optimization are presented. The pipeline network can be represented through a flow model, which can include a plurality of modeled wells operatively coupled to production facilities through one or more flowlines. Risk profiles of the one or more flowlines can be determined based on flowline attributes of each flowline and based on a simulation of the flow model that uses production variation in wells connected to the respective flowline as a parameter to generate flow profile of the flowline. Understanding the risk profile of each flowline through a risk metric can help assess the production potential of each flowline and wells associated thereto and optimize the network cost of operation or maintenance. | 06-19-2014 |
