Abstract:
A lighting device which can be used for illuminating pedestrian crossings or in other applications where it is necessary to form a defined and uniform rectangular pattern includes a parabolic reflector element and a planar screen with an array of cylindrical microlenses or microprisms on a surface thereof.
Abstract:
A method and apparatus of controlling supercharge pressure following rapid acceleration includes the steps of generating a pressure signal related to the value of the supercharge pressure of an engine; generating a reference signal related to a desired supercharge pressure value; generating a correction signal related to a time derivative of the pressure signal; generating an acceleration output signal as a function of a linear combination of the pressure signal, the reference signal and the correction signal; and supplying the acceleration output signal as a control signal.
Abstract:
The light radiation beam emitted by a source of finite dimension, integrated in a transparent plate or in contact therewith, is initially reflected inside the plate by a first surface located on the side of the plate (3) which is more remote from the source. The reflected light rays pass through plate and are again reflected by a second surface having micro projections and then directed outwardly, according to a micro-telescope arrangement.
Abstract:
An advanced driver assistance system (ADAS) configured to assist a driver in low visibility conditions. The ADAS controls operation of one or more automotive systems including an external lighting system, an automotive user interface, and an automotive cruise control system based on the visibility in front of the vehicle. The ADAS system visually assists the driver via an automotive user interface by displaying a streaming video of one or more first front cameras configured to operate in a spectrum visible to the human eye, one or more second cameras configured to operate in a spectrum invisible to the human eye, or a virtual depiction of an environment in front of or surrounding the motor vehicle based on information from an automotive sensory system.
Abstract:
A structural joint between two components of metal material is obtained by carrying out an electrical resistance welding spot between said components and subsequently performing a step of applying a cladding of metal material by an additive manufacturing technology. In one example, after a first step of applying a coarse base cladding, a second step of applying a fine cladding is carried out, again by additive manufacturing technology. The fine cladding can include a distribution of stiffening micro-ribs above the base cladding. The same method can also be applied to a single sheet metal component, rather than to a welded joint.
Abstract:
A gripping device has at least one tendon associated with a gripping arm and guided in a freely slidable manner along a first and second arm portion thereof through a succession of guiding elements. The guiding elements associated with a first proximal arm portion of the arms are carried by an inner yielding panel so that when the inner yielding panel on the inner side of the first proximal arm portion engages against an item or component to be gripped, the guiding elements of the tendon carried by the inner yielding panel cause a tensioning of the tendon, which results in an articulation and/or inflection movement of a second distal arm portion with respect to the first proximal arm portion.
Abstract:
A method for providing a welded joint includes: providing a first metal sheet having a first melting point; providing a second metal sheet having a second melting point, the second melting point being lower than the first melting point; providing a weld material; and joining the first metal sheet and the second metal sheet together by means of the weld material, thus defining a first joining interface between the first metal sheet and the weld material and a second joining interface between the second metal sheet and the weld material. The joining includes heating the second metal sheet at the second joining interface to a temperature higher than the second melting point, but lower than the first melting point.
Abstract:
An internal combustion engine includes an electro-hydraulic system for variable actuation of intake valves where each cylinder has two intake valves, associated with two intake conduits. A first conduit is generates within the cylinder a tumble motion of airflow introduced therein, when the intake valve associated thereto is at least partially opened. The second intake conduit generates within the cylinder a swirl motion of airflow introduced therein when the second intake valve is at least partially opened. A controller of controls one or more control valves to open only one of the intake valves of each cylinder in a condition of reduced engine operation, below a predetermined load and/or a predetermined speed of the engine, and to always open both intake valves in the remaining conditions of engine operation. The first intake valve is the only valve to be opened in the reduced engine operation condition.
Abstract:
System for automatically recognising anomalous situations along roads travelled by motor-vehicles for intelligent motor-vehicle driving speed control along roads. The motor-vehicles are configured to transmit data allowing anomalous situations to be recognised along roads travelled by the motor-vehicles. The system comprises data processing resources configured to: receive and process data transmitted by the motor-vehicles to recognise anomalous situations along the roads travelled by the motor-vehicles based on a recognition algorithm, when anomalous situations are recognised along roads travelled by the motor-vehicles, generate associated alert events and compute reference driving speeds along the roads recognised to be affected by anomalous situations, and transmit data representative of the alert events and of the reference driving speeds along the roads recognised to be affected by anomalous situations. The motor-vehicles are further configured to: receive data representative of alert events and reference driving speeds, and use the received data to implement one or both of the following actions: inform the drivers of motor-vehicles, through automotive user interfaces of motor-vehicles of the anomalous situations recognised along roads travelled by motor-vehicles, and cause current driving speeds of the motor-vehicles to be adjusted to the reference driving speeds along roads recognised to be affected by anomalous situations.
Abstract:
An automotive electronic dynamics control system for an automated motor-vehicle. The electronic dynamics control system is designed to implement two distinct Model Predictive Control (MPC)-based Trajectory Planners comprising a Longitudinal Trajectory Planner designed to compute a planned longitudinal trajectory for the automated motor-vehicle; and a Lateral Trajectory Planner designed to compute a planned lateral trajectory for the automated motor-vehicle. The electronic dynamics control system is further designed to cause the planned longitudinal trajectory to be computed before the planned lateral trajectory.
