  • Publication number: 20210270577
    Abstract: In an electronic dazzling element having at least one optical emitter with at least one electronic light-emitter for emitting light pulses, the light-emitter of the at least one optical emitter is controlled in such a way that a light pulse sequence emitted by the light-emitter is adapted to the physiology of the human eye.

  • Publication number: 20210254936
    Abstract: An electronic dazzling element has at least one optical emitter for emitting light pulses, which contains an electronic light-emitting device for generating light pulses, and a control device for controlling the light-emitting device of the optical emitter. In order to reduce the brightness reduction of the light pulses as a distance from the dazzling element increases, the optical emitter is configured to emit a collimated light beam. In order to simultaneously achieve the dazzling effect in as large a spatial region as possible, a beam direction of the collimated light beam may be changed.

  • Publication number: 20210254937
    Abstract: An electronic irritation device includes a plurality of electronic irritation signal modules. Each of the modules has at least one emitter for emitting optical or acoustic irritation signals, and additionally a connection device for coupling the plurality of irritation signal modules to one another and an unlocking device for automatically unlocking the connection device in order to decouple the plurality of irritation signal modules from one another and thereby distribute them spatially. Distributing a plurality of irritation signal modules makes it possible to increase the probability of an irritation effect upon deployment of a single irritation device.

  • Patent number: 10966672
    Abstract: A sliding arrangement for mobile X-ray devices enabling functionality for tomosynthesis acquisitions on systems without this functionality. The sliding arrangement substitutes a conventional X-ray collimator mount for fixing an X-ray collimator onto the gantry of a mobile X-ray system, and which adds the supplementary mechanical functionality that is required to perform tomosynthesis acquisitions.

  • Patent number: 10898156
    Abstract: A radiation image capturing system includes a processing unit that determines at least three distances between at least one first distance sensor provided at a radiation generation unit and at least three second distance sensors provided at a detection unit based on one or more signals emitted by the first distance sensor, and that determines an orientation of the radiation generation unit and the detection unit relative to each other based on inclination information provided by a first sensor unit provided at the radiation generation unit and a second sensor unit provided at the detection unit. Alternatively, the processing unit determines distances between at least three first distance sensors provided at the radiation generation unit and at least three second distance sensors provided at the detection unit based on signals emitted by the at least three first distance sensors to determine an orientation of the radiation generation unit and the detection unit relative to each other.

  • Patent number: 8987672
    Abstract: An apparatus and a corresponding system and method for reading out X-ray information stored in a storage phosphor plate includes a receiving device, in particular a cassette, for receiving the storage phosphor plate, a removal device for removing the storage phosphor plate from the receiving device, and a reading device for irradiating the storage phosphor plate removed from the receiving device with stimulation light and for detecting emitted light excited thereby in the storage phosphor plate. In order to permit as reliable a removal and/or return of the storage phosphor plate from and to the receiving device as possible while providing a simple design, the removal device has at least one removal element, which can be coupled to the storage phosphor plate and which can move along a curved path.

  • Patent number: 7498598
    Abstract: A system for reading out X-ray information stored in a phosphor layer, includes: a read-out unit having components for irradiating the phosphor layer with stimulation radiation which can stimulate the phosphor layer to emit emission radiation dependent upon the X-ray information contained in the phosphor layer, and for collecting the emission radiation stimulated in the phosphor layer; and a carrier onto which the read-out unit is mounted. At least one of the components of the read-out unit is mounted onto the carrier over at least one first bearing which has a translatory degree of freedom in a first direction.
