A tracking device (20, 20′) for tracking a tip (14) of an interventional instrument such as a catheter (10) during an interventional procedure performed on an associated subject (12) and monitored by magnetic resonance imaging includes a resonant circuit (22) disposed at the tip (14) of the catheter (10). The resonant circuit (22) includes a coil (32, 32′) having a coil inductance and a light-sensitive metal-insulator-semiconductor capacitor (30) optically coupled with an optical fiber (36) and having a selected capacitance determined by an intensity of light delivered by the optical fiber (36). A selected resonance frequency of the resonant circuit (22) is determined by the coil inductance and the selected capacitance. The resonance frequency is adjusted by modulating the intensity of light delivered to the light-sensitive metal-insulator-semiconductor capacitor (30).

An automatic transmission includes a single-pinion first planetary gear mechanism including a first sun gear, a first ring gear, and a first carrier that each correspond to one of first to third elements in a velocity diagram. A double-pinion second planetary gear mechanism includes a second sun gear, a second ring gear, and a second carrier that each correspond to one of fourth to sixth elements in a velocity diagram. The fifth element is connected to the second element to form a first connected body that is connected to an input shaft. A single-pinion third planetary gear mechanism includes a third sun gear, a third ring gear, and a third carrier that each correspond to one of seventh to ninth elements in a velocity diagram. The eighth element is connected to an output member, and the ninth element is connected to the third element to form a second connected body.

摘要:
A method of manufacturing an electronic device that comprises a microelectromechanical (MEMS) element, the method comprising the steps of: providing a material layer (34) on a first side of a substrate (32); providing a trench (40) in the material later (34); etching material from the trench (40) such as to also etch the substrate (32) from the first side of the substrate (32); grinding the substrate (32) from a second side of the substrate to expose the trench (40); and using the exposed trench (40) as an etch hole. The exposed trench (40) is used as an etch hole for releasing a portion of the material layer (34), for example a beam resonator (12), from the substrate (32). An input electrode (6), an output electrode (8), and a top electrode (10) are provided.

An automatic transmission includes first to third single-pinion planetary gearsets. The second ring gear and third sun gear are coupled to the first carrier and first ring gear respectively to constitute first and second rotor units. Input and output shafts are coupled to the second sun gear and third ring gear respectively. A first clutch selectively couples the first sun gear to the first carrier. A second clutch selectively couples the second sun gear to the third carrier. A third clutch selectively couples the second carrier to the second rotor unit. A fourth clutch selectively couples the second carrier to the third carrier. A first brake selectively holds the first sun gear stationary. A second brake selectively holds the third carrier stationary. At least eight forward gear ratios and one reverse gear ratio are obtained by simultaneous application of three of the clutches and brakes.

The invention relates to a solar cell that comprises a planar semiconductor substrate with a front and a back; a multitude of holes that interconnect the front and the back; and current-collecting electrical contacts that are exclusively arranged on the back. The front comprises highly doped regions and lightly doped regions of a first type such that in each case the holes are situated in a highly doped region or adjoin such a region. According to a first aspect of the invention, the highly doped regions are arranged locally around the holes. According to a second aspect of the invention, the front comprises at least one region without holes, and the highly doped regions comprise one region or several regions that extends/extend to the at least one hole-free region. The invention furthermore relates to methods for manufacturing such solar cells.

A solar cell device includes a solar cell with a semiconductor having at least one p-doped region and at least one n-doped region. Electrical p-contacts and n-contacts on the back of the solar cell are connected to correspondingly doped regions of the semiconductor. At least one p-busbar is connected to the electrical p-contacts and at least one n-busbar is connected to the electrical n-contacts. The busbars collect current of the electrical contacts and form a direction of longitudinal extension and a connection arrangement providing an electrically conductive connection of at least one busbar of the solar cell to at least one busbar of an adjacent solar cell. The connection arrangement includes at least one first connection section extending essentially perpendicular to the direction of longitudinal extension of the busbars, which connection section, by way of connection regions, is connected in a point-like manner with at least one busbar.
