Abstract: A sensor for a nuclear magnetic resonance device includes a magnetic field generation apparatus with a planar magnet arrangement for generating a static magnetic field in a useful volume. The planar magnet arrangement has a plurality of magnetic poles on a front side facing the useful volume, which are arranged adjacent to each other along an extension direction of the planar magnet arrangement with alternating orientation, and a measuring apparatus for measuring a signal based on nuclear magnetic resonance of a material sample arranged in the useful volume. The measuring apparatus includes an electrical coil having a winding for generating an alternating magnetic field in the useful volume, the winding arranged between two directly adjacent magnetic poles of the planar magnet arrangement such that the alternating magnetic field of the electrical coil is superposed with the static magnetic field of the planar magnet arrangement orthogonally in the entire useful volume.

Abstract: A wireless, handheld electrical therapy device delivers electrical pulses to a treatment area of a patient. In one embodiment, the device comprises a microcontroller-based pulse generator circuit selectively operable in a plurality of therapeutic modes. The device comprises an ergonomic housing adapted to be comfortably grasped by a user. A plurality of electrodes are disposed on a surface of the housing. In operation, a user brings the electrodes into contact with a patient's skin at a location on the patient to be treated. Electrical pulses are delivered between the electrodes, thereby electrically stimulating neural tissue at the treatment location. In one embodiment, the device is operable in a manual mode wherein the user selects from among a plurality of therapeutic regimens each corresponding to a set of predetermined operational parameters. Among the variable operational parameters are pulse amplitude, frequency, duration, damping, and shape.
