The invention relates to an amusement ride, such as a roller coaster, comprising a vehicle track and a speed trim system for reducing the speed of the passenger vehicle traveling along the vehicle track. The speed trim system comprises a magnet arrangement located on the passenger vehicle, at least one trim brake located along the track, one or more sensors for measuring the speed of the passenger vehicle approaching and/or passing the trim brake, and a control system. According to the invention, the trim brake comprises a pivotable supported induction blade, that can be pivoted about an induction blade pivot axis between an active position, for trimming the speed of the passenger vehicle while it passes the trim brake, and an inactive position.

An apparatus has a first portion of a magnetic braking system with a first element disposed thereon. The first portion rotates about an axis. The position of the first element is a fixed distance from the axis. A second portion of the magnetic braking system has a second element disposed thereon. A spring biases the rotatable first portion a first distance from the second portion. Upon application of a force to one of the portions, the relative position of the rotatable first portion to the second portion is reduced to a second distance less than the first distance.

Die Erfindung bezieht sich auf ein Schienenfahrzeug mit mindestens einem aus einem Traktionszwischenkreis (3) gespeiste, elektrische Fahrmotoren aufweisenden Motorwagen (1) und mindestens einem nicht angetriebenen Wagen (7;8), der durch mittels des Bremsstromes der Fahrmotoren erregbarer Wirbelstrombremsen mit vorgeordnetem Bremssteller (10) abbremsbar ist. Um ein solches Schienenfahrzeug verbrauchs- und kostengünstig herstellen zu können, ist der Bremsteller (10) der Wirbelstrombremsen über eine Anordnung (9) zur Bereitstellung einer Gleichspannung an eine Zugsammelschiene (5) mit einer erheblich unter dem Spannungsniveau des Traktionszwischenkreises (3) liegenden Gleichspannung (Uz) angeschlossen, wobei die Zugsammelschiene (5) über einen Umrichter (4) mit dem Traktionszwischenkreis (3) verbunden ist. Die Anordnung (9) zur Bereitstellung einer Gleichspannung und der Bremssteller (10) sind in dem nicht angetriebenen Wagen untergebracht.

Systems and methods for energy storage and management may be useful for a variety of applications, including launch devices. A system can include a direct current (DC) bus configured to operate within a predetermined range of voltages. The system can also include an array comprising a plurality of ultra-capacitors connected to the DC bus and configured to supply the DC bus with energy. The system can further include an input configured to receive energy from a power grid, wherein the power grid is configured to supply fewer than 250 amps of power. The system can additionally include an output configured to supply more than 250 amps of power. The system can also include a controller configured to control charging and discharging of the array of ultra-capacitors and configured to control the DC bus to remain within the predetermined range of voltages.

The invention relates to an eddy current brake (5; 105; 205; 305) for braking a rotating element (2), in particular a shaft, comprising at least one rotor disk (6; 106; 206; 306). In order to ensure that the strength and stiffness of the rotor disk are not detrimental to the magnetic permeability of the rotor disk and the electrical conductivity of the rotor disk, the at least one rotor disk (6; 106; 206; 306) according to the invention has a first partial disk (31; 131; 231; 331) and a second partial disk (32; 132; 232; 332), wherein the two partial disks differ in regard to the material of which they are composed. The invention further relates to an assembly, in particular a rail vehicle, comprising such an eddy current brake.

This eddy-current retarding device includes: a magnet holding member that is coaxially provided to a rotating shaft and holds plural permanent magnets in a circumferential direction; a brake member that includes paired disk portions disposed on both sides of the magnet holding member in the axial direction of the rotating shaft, a connecting portion that connects the paired disk portions, and an eddy-current generating portion that causes eddy current due to rotation of the permanent magnets, and this brake member being supported in a relatively rotatable manner with respect to the rotating shaft; and a friction brake that causes a friction member to press against the brake member at the time of braking to bring the brake member to a stop.

Exhaust gases can bypass a turbocharger (10) to reduce its speed, but energy in the gases is then lost. A brake for a turbocharger can be implemented using at least one rotor (30) driven by the turbocharger rotatable shaft (15) and at least one stator (40). Either the rotor or stator are magnetic, the other being ferrous, such that rotation of the shaft induces eddy currents in the ferrous part, thereby extracting energy from the shaft. The magnetic field experienced by the ferrous part can be adjusted in response to an input parameter to control the level of braking.
