摘要： A haptic system for providing a gait cadence to a subject comprising a portable telecommunication device with a control unit and a wireless transmission means; a vibrotactile device configured to be tightly worn on a portion of the subject's body, including at least one motor configured to generate vibrations that can be perceived by the subject and an actuation unit configured to actuate the motor. The actuation unit is configured to receive wireless signals from the wireless transmission means of the portable telecommunication device and to cause the motor to produce vibrations responsive to the wireless signals. In the control unit a generation program is resident configured to generate cadence signals and to transmit the wireless signals responsive to the cadence signals by the wireless transmission means to the actuation unit. The generation program is configured to provide corresponding cadence pulses to the motor.

摘要： A device for enhancing a user's grasping capability comprises a belt-like support configured to be tightly fitted about a user's part of the body; an articulated gripping element having a plurality of phalanxes: proximal, fixed to the support, intermediate and distal, which are articulated to each other by articular joints; a motor unit fixed to the support; a winding drum; a tendon partially wound on the drum and extending along the phalanxes and the joints, arranged so that, by pulling it from the drum, the phalanxes rotate about respective articular joints and move the articulated gripping element from an extended position to a gripping bow-shaped position, causing a flexion/extension movement of the articulated gripping element, the joints configured so that by releasing the tendon from the drum, the phalanxes rotate about the respective joints and move the articulated gripping element between gripping bow-shaped position and extended position.

摘要： A system (50) for tracking an object (1) comprises a magnetic field source (10) configured to be fixed to this object (1); a magnetometric data collection unit (20) that uses magnetic field sensors (22) fixed at predetermined positions on a support (23) to form an array (21), and that includes a sensor control unit (25) for controlling the magnetic field sensors (22); a data processing unit (30) configured to receive the magnetic field data from the sensor control unit (25) and to calculate from these data position coordinates of the magnetic field source (10) with respect to the array (21) forming a vector of such position coordinates which minimizes the distance between magnetic field values expected at the sensor positions (22) and magnetic field values collected by the collection unit (20), wherein the magnetic field source (10) is arranged to generate a local magnetic field (4), at the magnetic field sensors (22), of intensity set between 5 and 500 microtesla, so that the magnetic field sensors (22) detect both the local magnetic field (4) and the geomagnetic field (5), and wherein the data processing unit (30) is configured to recognize contributes of the local magnetic field (4) and of the geomagnetic field (5) in the magnetic field data, and is configured to determine location and of orientation coordinates of the magnetic field source (10) with respect to the array (21), as well as orientation coordinates of the array (21) with respect to the geomagnetic field (5). This way, an accurate tracking can be obtained of the displacements of the object (1) even if the array (21) is connected to a support that is movable with respect to an absolute reference system integral to the geomagnetic by fixing array to the subject's head.
