Abstract: An electric vehicle charging system includes an interleaved DC-DC control system configured to facilitate providing electric charge to an electric vehicle battery and includes a controller communicatively coupled to the interleaved DC-DC control system. The interleaved DC-DC control system includes an inrush current limiting circuit, three parallel boost converters that are each configured to operate in a discrete phase, and unidirectional current circuitry. The controller includes electronic control circuitry configured to control the interleaved DC-DC control system and vehicle communication circuitry configured to establish charging protocols between the interleaved DC-DC control system and the electric vehicle battery.

Abstract: Engine control apparatus includes, but is not limited to a determining device for determining whether or not the engine is operated under predetermined deceleration operating conditions or predetermined acceleration operating conditions and for individually deactivating two or more cylinders in a disenabling sequence which is different from the firing sequence if the engine is operated under predetermined deceleration operating conditions, and/or for individually reactivating two or more of the cylinders in a reactivating sequence which is different from the firing sequence if the engine is operated under predetermined acceleration conditions.

Abstract: Passive shroud cooling of rotor blades (5) is accomplished by a multitude of cooling-air flows introduced into the hot-gas flow upstream of the rotor blades on the outer circumference, these cooling-air flows, depending on the aerodynamic and geometrical conditions, being orientated at a defined radial angle and a circumferentially related tangential angle such that the cooling air primarily and essentially hits the thermally highly loaded bottom surface (11) of the outer shrouds (6) allover. In the apparatus for the performance of the method, cooling air passages (9) tangentially and radially orientated to the hot-gas flow are provided in an area of a casing section (3) which protrudes beyond the stator blades (1) in the downstream direction, this casing section (3) interrupting the transport of cooling air in the axial direction.

Abstract: A telecommunication network is monitored for fault conditions. In order to correlate the alarms to established which alarms have a common cause, a logical connectivity model is used in which a logical property is transferred between related logical elements in response to the element being alarmed. If as a result of such transfer the value of the logical property exceeds a threshold value for any element a correlation is established and the element highlighted as the probable cause of the alarms.
