Abstract: The movement of a part of human body, e.g. a limb, is monitored. The movement includes N iterated rotations in a plane. A sensing device is fixed to the limb and provides data indicative of the limb movement. These data are processed to generate a rotation signal. Then, portions of the rotation signal corresponding to each movement iteration are identified. To this purpose, a plurality of null-velocity instants is identified, wherein the angular velocity of the sensing device is null. Then, each null-velocity instant is classified as a candidate start/end time or a candidate peak time. Then, a start time, end time and peak time for each iteration are determined as a combination of two candidate start/end times and a candidate peak time that fulfils certain conditions on the values of the rotation signal in correspondence of candidate start/end times and candidate peak times.

Abstract: A diesel engine system includes a diesel engine, an exhaust line, a particulate filter interposed in the exhaust line and an electronic control unit for controlling fuel injectors associated with cylinders of the engine. When an accumulated particulate mass in said filter reaches a predetermined threshold, a filter regeneration mode is activated, including activating post-injections of fuel by controlling said injectors, to determine a start of an automatic filter regeneration step, which is caused by an increase in temperature of exhaust gases fed to the filter. The temperature increase is sufficient to burn particulate in the filter. The post-injections of fuel are deactivated whenever a critical condition occurs for at least a first period of time, the critical condition being one in which a temperature value upstream of the filter exceeds a first threshold value. In this case, the regeneration mode is resumed following disappearance of the critical condition.

Abstract: Particulate accumulation in a particulate filter in the exhaust line of an engine is calculated by an electronic engine control unit. When the estimated accumulated particulate mass exceeds a predetermined threshold, an automatic regeneration step of the filter is activated. An actual instantaneous burned particulate mass is calculated as a function of values indicative of the state of the filter. A temporary correction factor representing an error between a theoretical value and the actual value is calculated. The temporary correction factor is stored in a second map of correction factors, based on the engine operating conditions. During an accumulation step, the estimated instantaneous particulate mass, calculated according to the first map based on the operating conditions of the engine, is multiplied by a correction factor calculated according to the second map based on the operating conditions of the engine.

Abstract: A motion capture system includes a wearable device (e.g. a glove) suitable for being worn by a user and including one or more markers having respective colors. A video camera acquires a sequence of color frames of the user moving while wearing the glove, while a range camera acquires corresponding depth frames of the same scene. A processing unit processes both color frames and depth frames for reconstructing the 3D positions of the markers. In particular, the depth information provided by the depth frames are used for isolating a validity area within the color frames, and the markers are searched based on their colors, exclusively within the validity area of the color frames. The movements of the user are then captured as a sequence of positions of the markers. Combined use of color information and depth information provide a very reliable and accurate motion capture.
