Abstract: A sensor system for positioning, orienting, and/or aligning a sensor assembly to a target object are provided. In some embodiments, the sensor system can include a sensor assembly and a control and processing module coupled to the sensor assembly. The control and processing module can be configured to process signals generate by the sensor assembly. The sensor system can include a mounting assembly configured to receive the sensor assembly and to position the sensor assembly relative to a surface of a target object. The mounting assembly can include a retaining element configured to translate along a first axis.

Abstract: Systems, methods, and devices for positioning, orienting, and/or aligning a stress sensor assembly are provided. In some embodiments, a sensor assembly can be received within a retaining element of a sensor mounting assembly. The sensor mounting assembly can include the retaining element, an adjustment mechanism, a first member, a second member, and a third member. The adjustment mechanism can allow the sensor assembly to be displaced linearly in a proximal and/or distal direction. The first and second members can be pivotally coupled to enable the sensor assembly to be rotated about a first axis, and the second and third members can be pivotally coupled to allow the sensor assembly to be rotated about a second axis.

Abstract: A method for detecting the opening of a passive pressure control valve, which conducts fuel from a common rail system back to a fuel tank, in which the rail pressure (pCR) is automatically controlled by calculating a correcting variable for acting on the controlled system from a rail pressure control deviation via a pressure controller, and in which, starting from a steady-state rail pressure in normal operation, a load reduction is detected when the rail pressure exceeds a first limit. Opening of the pressure control valve is detected after the first limit is exceeded if a steady-state operating state is subsequently detected again, and if a characteristic of the closed-loop control system deviates significantly from a reference value.

Abstract: In a method for detecting the opening of a passive pressure limiting valve for releasing fuel from a common rail fuel injection system to a tank with a fuel supply including a throttle wherein, based on a stationary rail pressure present during manual operation, a load reduction is detected when the rail pressure exceeds a first limit value and, as a result, a PWM signal for controlling the suction throttle is temporarily increased, the opening of the pressure limiting valve is recognized if, as a result, the rail pressure exceeds a second limit value and increases still further.
