Abstract: A method for generating a series of questions from a presentation that includes receiving information materials for a presentation session, and converting the information materials into a text based data element. The method further includes comparing the text based data elements to a knowledge base directed to topics of interest to score the text based data elements for priority, and transforming text based data elements having a score above a threshold value into plurality of quiz metadata objects. The quiz metadata objects include context from the topics of interest. The method further includes generating quiz questions from the plurality of quiz metadata objects using the context and a set of templates of question types.

Abstract: A heating device for an exhaust system of an internal combustion engine and having: a main tubular body, which contains a combustion chamber delimited by a first base wall and by a second base wall, which are opposite one another; a fuel injector configured to inject fuel; an inlet opening, which can be connected to a fan to receive an air flow, which is directed to the combustion chamber and gets mixed with fuel; a secondary tubular body which is arranged inside the main tubular body and inside the combustion chamber and has a side wall, which is arranged at a given distance from the side wall of the main tubular body so as to divide an initial part of the combustion chamber into a central zone, which is located inside the secondary tubular body, and an annular peripheral zone, which is located around the secondary tubular body.

Abstract: A heating device for an exhaust system of an internal combustion engine and having: a tubular body, where a combustion chamber is obtained on the inside; a fuel injector, which is designed to inject fuel into the combustion chamber; at least one inlet opening, which can be connected to a fan so as to receive an air flow, which is directed to the combustion chamber; a feeding channel, which receives air from the inlet opening, surrounds an end portion of the fuel injector and ends with a nozzle, which is arranged around a spray tip of the fuel injector, from which fuel flows out; and a spark plug, which is mounted through a side wall of the tubular body. An axial distance, namely measured along a longitudinal axis of the tubular body, between the spray tip of the fuel injector and a longitudinal axis of the spark plug ranges from 33% to 100% of an inner diameter of the tubular body.

Abstract: A microelectromechanical gyroscope device has: a detection structure, provided with a mobile mass; and an integrated electronic circuit, coupled to the detection structure and which provides a bias signal to the detection structure to cause its oscillation at a resonance frequency and acquires a detection signal from the detection structure indicative of a detected angular velocity. When the gyroscope device is powered, the integrated electronic circuit implements a start-up phase, following a previous power-down, wherein the mobile mass is biased to have an increase in the oscillation up to a target oscillation amplitude, followed by a maintenance phase at the target oscillation amplitude. The integrated electronic circuit is provided with a time counter stage for measuring a duration of a time interval from the previous power-down and adjusts the bias of the mobile mass during the start-up phase as a function of the measured duration of the time interval.

Abstract: A method and an apparatus for packaging products susceptible of absorbing carbon dioxide, in particular perishable food products. The method comprises the step of inserting a product in a containment package and the step of sealing the package. Before sealing, a preset amount of solid-phase carbon dioxide is introduced in the containment package. The sublimated carbon dioxide is then absorbed by the packaged product, avoiding collapse of the package.

Abstract: A pressing machine arrangement, comprising at least two dies defining a molding cavity is described.The main feature of this machine is to comprise means for adjusting the thrust pressure exerted at least on one of the said dies (22, 255), substantially in every region of the said dies, in order to maintain substantially mating, during the stage of maximum thrust, the contours of the said dies (22, 7, 255, 332) which define the said molding cavity, by means of an analogous deformation for the said two dies. Said means comprise a cylinder (77, 213) whose head (76, 216) acting into the said dies has a relatively reduced thickness, so as to allow its deformation.
