Abstract: A vehicle cockpit component, for example a vehicle seat, is equipped with a heating and cooling device incorporated in the padding and/or upholstery of the component, and whose operation is based on the Peltier effect. The padding and/or upholstery of the cockpit component comprises a foam element containing one or more intrinsically electrically conductive polymers which are altered so as to create p-type regions and n-type regions. The device has several advantages, including in particular a reduced number of components, reduced energy consumption, reduced emission of pollutants, elimination of moving fluids, and, more generally, moving parts, and quicker heating/cooling, with consequent improvement of the user's comfort.

Abstract: A sound transmission system for a headrest has a bone conduction speaker and bone conduction microphone mounted on the same printed circuit board. Additional components of the bone conduction two-way sound transmission system, such as a control unit, contact sensors or proximity sensors, and an antenna for communication with external electronic devices can be mounted on the same printed circuit board.

Abstract: A headrest having a bone conduction two-way sound transmission system is provided. The system has a bone conduction speaker and bone conduction microphone mounted on the same printed circuit board. Additional components of the bone conduction two-way sound transmission system, such as a control unit, contact sensors or proximity sensors, and an antenna for communication with external electronic devices can be mounted on the same printed circuit board. Assembling the components of the system is easy and subsequent assembling the two-way sound transmission system inside the headrest is simpler, faster, and less subject to human errors, thus increasing the quality of the final product while keeping the manufacturing costs low.

Abstract: A vehicle cockpit component (10, 12, 14, 16, 18) with a heating device that comprises a polyurethane-based foam charged and/or impregnated with an electrically conductive filler (1) which is directly connected to means for generating a potential difference (7a, 7b; 11a, 11b; 13a, 13b) for generating heat by Joule effect is provided. The polyurethane-based foam charged and/or impregnated with an electrically conductive filler (1) is used for manufacturing the padding or the upholstery of the vehicle cockpit component (10, 12, 14, 16, 18) or one or more portions of the padding or upholstery. The heating device is intrinsic to the vehicle cockpit component and does not require the provision of additional, separate components.

Abstract: Technical solutions are described for optimizing current injection profiles used for solenoid injectors, such as during fuel injection. An example fuel injector system includes a solenoid injector and a controller that receives a request for energizing the solenoid for an energizing time. The controller, in response to the requested energizing time exceeding a predetermined threshold, holds an electrical current applied to the solenoid injector at a predetermined minimum holding value for a holding phase. Further, the controller in response to the requested energizing time being less than the predetermined threshold, applies a predetermined peak-current value to the solenoid injector.
