The embodiments include a magnetic resonance device having a head antenna unit configured for acquiring magnetic resonance signals, and a projection unit that has a presentation surface unit for presenting picture elements and a first projection surface unit for presenting a projection of the picture elements. The receiver has on each outer side a groove or ridge for use in initial engagement of the test adapter with the receiver. The first coil of the array has two solenoidal sections that are separated from one another along a common axis. The pour aperture has a curved configuration extending laterally on each side of a central axis line that bisects the closure body, and the vent aperture is further defined by a downwardly extending vent tube. The radio unit further comprises a coefficient computation engine configured to calculate coefficients used by the digital pre-distortion engine to pre-distort the modulated digital data signal. During a focusing operation the area of interest within the constraints of the Data Pane window is expanded, and related or more detailed data is presented to the user.
