The present disclosure relates to charging energy stores, for example for charging electrical vehicle batteries. Various embodiments may include methods for controlling charging operations. For example a method for controlling charging operations of a plurality of electric vehicles may include: analyzing a data record including arrival times, departure times, and charging energies of the plurality of electric vehicles during a first time period; determining an upper limit for charging power based on the data record, the determined upper limit for charging power defined by an amount of power required to charge each electric vehicle between its respective arrival time and departure time; and charging the electric vehicles without exceeding the determined upper limit for charging power during a second time period following the first time period.

Method for controlling charging operations

A method for determining the energy consumption of a production system such that the production system can be planned and operated more efficiently in terms of energy, where a load profile of the production system is determined, an energy requirement of the production system is estimated, an energy model of the production system is determined and the energy consumption of the production system is determined.

Method for determining and optimising the energy consumption of a production system

A two-channel magnetic resonance tomography system is provided with a regulation circuit for an amplification system in order to be able to take into account different load situations of the MRI system in a flexible and efficient manner. It is thus possible to improve the MRI measurements greatly if the MRI system is set to the respective load situation beforehand by an idle state measurement. The adaptation may optionally also be carried out during the MRI measurement. Therefore, a multiplicity of completely different load situations may be taken into account in an optimized manner by the regulation circuit.

Two-channel magnetic resonance imaging

A DC voltage source, for example an AC/DC converter, has an output producing a controllable DC voltage for a DC charging station to charge the battery of an electric vehicle. A voltage balancing unit is connected between the output of the converter and the output terminal of the DC charging station. The voltage balancing unit has a controllable switch by which the connection between voltage source or converter and battery can be made or broken as desired. The switch is controlled as a function of the voltage on the input and output side of the voltage balancing unit to the effect that the switch breaks the connection before and while the battery is being connected to the DC output terminal, and makes a connection only when the voltage on the input side of the voltage balancing unit corresponds substantially to the voltage on the output side of the voltage balancing unit.

A circuit arrangement has a bidirectional AC/DC converter connected to a first side of a DC/DC converter at a DC side of the AC/DC converter via first electric switch. The AC/DC converter is connected to a second side of the DC/DC converter at the DC side of the AC/DC converter via a second electric switch. The first side of the DC/DC converter is connected to a third electric switch and can be connected to an energy storing device via said switch. The second side of the DC/DC converter is connected to a fourth electric switch and can be connected to an energy generating device via said switch. The AC/DC converter can be connected to the electric supply grid at the AC side of the AC/DC converter. A control device controls the switches and the converters.

Circuit arrangement

An endoscopy system has an endo-robot that is navigable within an anatomical lumen of a patient by interacting with a magnetic field generated by an extracorporeal magnet system. The patient lies on a patient bed that is movable in one or more directions and/or orientations, and an obstacle detects objects in the movement path of the endo-robot in the anatomical lumen and produces a signal that causes the position and/or orientation of the patient bed to be altered dependent thereon.

Endoscopy system

A charging post at a charging station for charging an electric vehicle can be lowered into the ground by a lifting device such that it does not become a physical obstacle or optically impair the environment and is not damaged by external influences.

A solenoid system for magnetically guided capsule endoscopy, has the following components arranged under a patient table which defines a flat plane: a central coil with normal direction being perpendicular to the flat plane, and four coil pairs arranged in the form of a cross around the central coil with respect to the flat plane. Each pair includes two single coils, the normal directions of which are parallel to the flat plane and offset by 90 degrees in relation to each other.

Solenoid system for magnetically guided capsule endoscopy

A magnetically guided endoscopy capsule is separated from the surface of water with the aim of immersing the capsule completely in water, using the least possible magnetic force. A brief force curve (F_mag(t)) is thereby automatically generated on the capsule by a solenoid system, by one or more force pulses. Assuming that the capsule floats on the water surface at the start of the force curve, a force curve is applied generating an odd number of force pulses having a step profile. Each odd force pulse brings about at least a partial immersion of the endoscopy capsule in the liquid, and each even force pulse bring about at least a partial emersion of the endoscopy capsule out of the liquid.

Separating endoscopy capsule from surface of liquid

A coil system for the contactless magnetic navigation of a magnetic body in a work space, has a plurality of coils and a current controller for controlling the respective currents in the plurality of coils. In order to navigate the magnetic body to a variably predeterminable position in the work space, the current controller is designed such that the currents in the plurality of coils are such that the magnetic forces generated by the currents and acting upon the magnetic body at multiple positions at the edge of a convex environment around the predetermined position are directed into the environment. The coil system has the advantage that a movement of the magnetic body toward a spatial position is achieved without any mechanical movement of the coil system and without a positioning system for determining the position of the magnetic body. The coil system is utilized particularly in a medical device, wherein a magnetic body in the form of a probe is moved in the body of a patient. In this way, fast navigation of the probe in the patient's body can be achieved without mechanical movements of the patient table or of the coil system.

In order to achieve an improved or optimized operation mode of an 'expanded drying section' of a paper machine&#x2014;having the 'actual' drying section, separated, if applicable, into pre-drying and post-drying sections with a size press located therebetween, a steam and condensate system, an exhaust air heat recovery system, a wet press and the white water&#x2014;a model that includes the above system components is proposed, with which mass and energy balances for the system components as well as the specific energy consumption of the drying section are calculated, based on values for parameters relevant for the drying process.

A system includes a capsule body having a casing introduced into a subject to perform, in liquid, examination of or treatment on the interior of the subject, the casing containing a permanent magnet, a mass of the casing excluding the magnet being set to be less than a product of a volume of the casing and a density of the liquid; a magnetic field generator that generates a magnetic attraction for the magnet to guide the capsule body; and a magnetic field generation device that controls the magnetic field generator to generate the magnetic attraction by setting a maximum value of the generated magnetic attraction vertically upward to the capsule body, to be equal to a maximum value of the generated magnetic attraction vertically downward to the capsule body, and by setting the maximum values to be less than a value obtained by multiplying a mass of the magnet by a gravitational acceleration.

Capsule medical apparatus guidance system

A coil system for the contact-free magnetic navigation of a magnetic body with a magnetic dipole moment in a working chamber, a number of coils and a current control unit for controlling the respective currents in the multiple coils. The current control unit generates a force on the magnetic body in a predefined direction by setting the currents in the multiple coils so that the direction of the force generated by the currents on the magnetic body at each position among a number of positions in a volume in the working chamber essentially corresponds to the predefined direction of force. This coil system has the advantage that the position of the magnetic body in the working chamber does not need to be known exactly in order to move the body in a desired direction or to align the body in a desired orientation direction. This coil system suitable for use in a medical device and by special preference in a device for capsule endoscopy. In this situation, the magnetic body is a capsule that can be navigated in the body of a patient and has an imaging system for capturing images of the internal organs of the patient and a transmit module for sending the captured images to a receiver.

Coil system for the contact-free magnetic navigation of a magnetic body in a working space

An endoscopy capsule contains an induction coil that is elongated along a longitudinal axis thereof, the endoscopy coil supplying power to components within the endoscopy capsule. A magnetic element in the endoscopy capsule has a magnetic dipole moment and interacts with an external magnetic field to navigate the endoscopy capsule within the body of a subject. The magnetic element is oriented so that the magnetic dipole element is aligned perpendicularly to the longitudinal axis of the induction coil. The endoscopy capsule has a cross-sectional area, in a plane having a normal aligned in the direction of the longitudinal axis of the induction coil, which contains both a cross-section through the magnetic element and a cross-section through the induction coil. The magnetic element has a length along the longitudinal axis of the induction coil so that the magnetic element projects beyond the induction coil at each end thereof.

Endoscopic capsule

A coil arrangement for contact-free guidance of a magnetic element such as an endoscopy capsule, has a number of individual coils arranged in pairs by which the components of a guidance field are generated. By arranging the individual coils to include coils corresponding to blades at an exterior of a cylindrical surface, the number of degrees of freedom required for guidance can be obtained with fewer individual coils and fewer power amplifiers to operate the coils.
