The present embodiments relate to a gantry for the beam guidance of a particle beam with at least one beam guidance element. According to one embodiment, the display panel is placed in the lower possible refresh rate that can be supported. The dry electrolyte is configured to be activated by a first biological fluid to electrically connect the first anode and the first cathode to generate an electrical current. A lighting driver circuit is to be coupled to a light source and coupled to receive the ac signal from the control circuit. In this way, decrease in whole thickness is achieved. In some embodiments, the computer provides the recorded video and information to other locations and parties, for example, to a director remotely overseeing filming.
