A linear energy harvesting device that includes a housing and a piston that moves at least partially through the housing when it is compressed or extended from a rest position. When the piston moves, hydraulic fluid is pressurized and drives a hydraulic motor. The hydraulic motor drives an electric generator that produces electricity. Both the motor and generator are central to the device housing. Exemplary configurations are disclosed such as monotube, twin-tube, tri-tube and rotary based designs that each incorporates an integrated energy harvesting apparatus. By varying the electrical characteristics on an internal generator, the kinematic characteristics of the energy harvesting apparatus can be dynamically altered. In another mode, the apparatus can be used as an actuator to create linear movement. Applications include vehicle suspension systems (to act as the primary damper component), railcar bogie dampers, or industrial applications such as machinery dampers and wave energy harvesters, and electro-hydraulic actuators.

A method for determining the spatial distribution of magnetic resonance signals from at least one of N subvolumes predefines a reception encoding scheme and determines unique spatial encoding for at least one of the subvolumes but not for the entire volume under examination (UV). A transmission encoding scheme is also defined, wherein encoding is effected via the amplitude and/or phase of the transverse magnetization. The temporal amplitude and phase profile of the RF pulses is then calculated and each reception encoding step is carried out I times with variations according to the I transmission encoding steps in the transmission encoding scheme. The method makes it possible to largely restrict the spatially resolving MR signal encoding and image reconstruction to subvolumes of the object under examination without the achievable image quality sensitively depending on imperfections in the MR apparatus.

The present invention relates to a hinge for pivotable connection of two components (1, 2), consisting of at least one first round hinge element (3, 4) at the first component (1) and at least one corresponding second round hinge element (5, 6) at the second component (2), which hinge elements (3, 5; 4, 6) are connected together to be rotatable about the center axis. The first hinge element (3, 4) is a bearing sleeve (7, 8) with a longitudinal gap, by way of which an insertion sleeve (11, 12), similarly provided with a longitudinal gap (13, 14), as second hinge element (5, 6) can be rotated into place in its entirety.

A method for obtaining amplitude and phase dependencies of radio frequency pulses, which are irradiated within the scope of a main magnetic resonance experiment for generating a predetermined n-dimensional spatial distribution (n>=1) of transverse magnetization in an object by means of at least one radio frequency transmitting antenna of a magnetic resonance measuring system in combination with spatially and temporally varying additional magnetic fields which are superimposed on the static and homogeneous base field of the magnetic resonance measuring system and change the transverse magnetization phase in the object in dependence on location and time is characterized in that, prior to performance of the main experiment, a preparational measurement is performed in which the change with time of the transverse magnetization phase in the object under the action of the additional magnetic fields is measured in a position-resolved fashion and the amplitude and phase dependencies of the radio frequency pulses for the main experiment are calculated on the basis of this change with time of the transverse magnetization phase, which is measured in a position-resolved fashion. In this fashion, experimental imperfections in the form of unintentional additional magnetic fields can be measured, taken into consideration and compensated for.

Electromotive furniture drive for displacing parts of a piece of furniture relative to one another. The drive includes a drive element that can linearly move along a linear motion axis. This drive is provided for pivoting a pivotal element, which can pivot about a pivot axis and which, when the furniture drive is in a mounted position, is actively connected to a part of the piece of furniture to be displaced. An element may be provided that, during the displacing motion, maintains the engagement between the drive and the pivotal element at a point P that is essentially fixed along the linear motion axis. The furniture drive can be easily and economically produced and has a sturdy design.
