Abstract: A hull-fitted electronic device (2) for a vessel is provided. The hull-fitted electronic device is adapted to be attached to a seat (10) having a through hole (11), the seat being attachable to a hull (20) of the vessel such that the through hole of the seat is aligned with a through hole (12) of the hull. The hull-fitted electronic device comprises a transducer (16) adapted to generate a signal to be transmitted into the water outside the hull, and a housing (14) encapsulating the transducer and having a lower portion (3) and a flange portion (4). The lower portion and at least the portion of the flange portion located closest to the lower portion are covered by a surface (5) of a material (17) being watertight and transparent to the signal generated by the transducer. A portion of the surface forms a window (13) of the housing arranged to transmit the signal of the transducer.

Abstract: The present invention relates to a system (10) operable to evaluate spasticity in a movable extremity (12). The system (10) comprises a fixation device (14) comprising a first part (14.sub.1) connected via a movable joint (16) to a second part (14.sub.2). The fixation device (14) is operable to fix the movable extremity (12) in such a way that the rotational axis of the fixation device (14) is aligned with the rotational axis of the joint of the movable extremity (12). The system (10) also comprises a moving device (18) operable to move the second part (14.sub.2) with a first, constant velocity (V.sub.1), without any reflex contribution, and with a second, constant velocity (V.sub.2) with reflex contribution. The system (10) also comprises a force sensor (20) operable to measure a first force trace in connection with the first velocity (V.sub.1), and a second force trace in connection with the second velocity (V.sub.2).
