摘要： A test apparatus for testing an IR sensor of train undercarriage temperatures is disclosed. The IR sensor may be used to obtain infrared IR emission data by sensing a wheel or a wheel bearing of a rail vehicle. The test apparatus may comprise a heat emitter for supplying IR emissions at a reference temperature to the IR sensor. A support may support the heat emitter at a position spaced from the passage of the rail vehicle and in an orientation for directing the IR emissions at the IR sensor.

摘要： A fuel injector provided with: an injection valve comprising an injection nozzle; a mobile needle for adjusting the flow of fuel through the injection valve and ending in a shutting head which engages a valve seat of the injection valve; an actuator for displacing the needle between a closing position and an opening position of the injection valve; a catch element which constitutes an upper end stroke of the needle and defines the opening position; and a mechanical damping device which is interposed between the needle and the catch element and which is adapted to generate on the needle an elastic force which opposes to the movement of the needle towards the opening position when the needle is in proximity of the catch element.

摘要： An electroacoustic earcup for open-back headphones may include: a housing extending in a main direction, wherein the housing includes a first wall with a first opening and a second wall with a second opening, wherein the first and second walls are transverse to the main direction and are connected by a side wall; an air-permeable earpad whose shape mates with that of a human ear, wherein the air-permeable earpad is operably connected in fluid communication with the first opening; an air-permeable cover which is operably connected in fluid communication with the second opening; and a first electroacoustic transducer and a second electroacoustic transducer in the housing, one behind the other in the main direction. Each of the first and second electroacoustic transducers may include a diaphragm, configured to vibrate, facing the first opening. Each of the first and second electroacoustic transducers may define an input surface facing the second opening.
