Abstract: An antenna device (10?, 10?, 10??, 10??) for seismic surveys, where the antenna (10?, 10?, 10??, 10??), when in the active position, is located by the seabed (2), and where the antenna (10?, 10?, 10??, 10??) is coupled to one end portion of at least one feed-out hollow element (12a, 12b), the opposite end portion of the feed-out hollow element (12a, 12b) being coupled to a fluid supply (14a, 14b, 16).

Abstract: A method and device for training pelvic floor muscles in order to treat or prevent urinary or fecal incontinence. The device comprises a probe having a pressure sensor and a vibrator, and a microprocessor connected with the sensor and the vibrator. Initially, the probe is inserted into a person's vagina or rectum and the highest force that can be applied by the person contracting the pelvic muscles is ascertained and registered. The contraction of the pelvic floor muscles is repeated at intervals, and the force applied by pelvic floor muscles at each contraction is ascertained and compared with the registered highest value. The vibrator is activated at each contraction of the floor muscles only if the force has a predetermined relationship to the registered value, and only for a predetermined period as long as the predetermined relationship is maintained.
