Abstract: A bidirectional resonant DC/DC converter comprising a full-bridge coupled to an CLLLC resonant tank and a power transformer and rectifier stage, said full-bridge comprising two pairs of power switches S1/S2 and S3/S4, configured such that in a first mode of operation: switches S1 and S4 are driven by the same two pulse pattern with a phase shift ?1, said two pulse pattern comprising a first pulse P1 of width t1 and a second pulse P2 of width t2, P1 and P2 being separated by an off-time t3, and switches S2 and S3 are driven by the same single pulse pattern comprising pulse P4 of width t4 with a phase shift ?2. This converter can be used in battery chargers, in particular, for electrical vehicles.

Abstract: A charger operable to charge a battery of an electric vehicle from an electric power grid. The charger includes a first connector unit operable to connect the charger to the electric power grid, an AC/DC converter, a set of filters provided between the first connector unit and the AC/DC converter, a second connector unit operable to connect the charger to the battery, and a configurator provided between the first connector unit and the set of filters, the configurator being provided with a set of switches and/or relays operable to switch between a three-phase operation and a single-phase operation to charge the battery from the electric power grid.

Abstract: Disclosed herein are cargo carrying nanoparticles and pharmaceutical formulations thereof. The cargo carrying nanoparticles can self-assemble from cargo molecule subunits and/or targeting subunits. The cargo carrying molecules can be configured to induce macropinocytosis in a cell when a targeting moiety specifically binds a binding partner on the surface of a cell. The pharmaceutical formulations containing the cargo carrying nanoparticles disclosed herein can be administered to a patient for the treatment or prevention of cancer.

Abstract: A pneumatic system designed to minimize the high coefficient of water friction, known in the nautical industry as “skin resistance” or “drag,” against the submerged hull (10) area of a vessel. This system directs pressurized air from a shipboard compressor (30) through many distributing pipes (60). These distributing pipes (60) are arranged longitudinally and are evenly spaced transversely, adjacent to the internal hull (10) section that lies below the waterline. A plurality of smaller ejection pipes (70) project from the distributing pipes (60). Calibrated nozzles (80) connect the ejection pipes (70) to the vessel's exterior, releasing a constant flow of pressurized air as bubbles between the water (A) and the hull (10) surface. This layer of bubbles reduces the undesired effect of skin resistance (drag) caused by the viscosity of the medium through which the vessel navigates.
