Abstract

The invention relates to a method for operating a broadband lambda probe which has a measuring space that communicates with a measuring gas and which has an electrochemical pump cell with which oxygen can be transported into the measuring space and out of the measuring space according to the total pump voltage (Up) applied to said pump cell and according to a pump current (Ip) which results therefrom, and which has an electrochemical Nernst cell at which the Nernst voltage (Un) is formed according to the ratio of the oxygen content in the measuring space relative to the oxygen content in a reference space of the broadband probe. The method provides a control loop whose actual value is the Nernst voltage (Un), whose setpoint value is a predefined value (UnSet) and whose manipulated variable is the pump current (Ip). In order to protect the pump cell the manipulated variable of the pump current (Ip) is subjected to limitation by an upper limiting value (LL) and/or by a lower limiting value (LR) by means of a further effective loop, the upper limiting value (LL) and/or the lower limiting value (LR) each being determined in a variable fashion in accordance with the pump current (Ip), the pump voltage (Up) and the internal resistance (R) of the pump cell.

Abstract

The invention relates to a method for determining a change in a range of a lidar sensor (1) for a vehicle or a robot. According to the invention, in a reference measurement with a reference target (RZ) situated at a predefined distance (d_0) from the lidar sensor (1), a reference noise level (R_0) of infrared radiation (S) received by means of the lidar sensor (1) and a signal-to-noise ratio of infrared radiation (S) reflected at the reference target (RZ) and received by the lidar sensor (1) are determined. In a driving operation measurement, during driving operation of the vehicle or robot, a current noise level (R_1, R_2) of infrared radiation (S) received by means of the lidar sensor (1) is determined and the current noise level (R_1, R_2) is used to determine a theoretical distance (d_1, d_2) with respect to a position (P_1, P_2) at which the reference target (RZ) would have to be situated if the same signal-to-noise ratio as for the reference measurement were present given the current noise level (R_1, R_2). In a range change calculation, a deviation between the predefined distance (d_0) and the theoretical distance (d_1, d_2) is determined, the deviation corresponding to the change in the range of the lidar sensor (1) relative to the range thereof during the reference measurement.

Abstract

The invention discloses a method and a system (100) of operating a gas sensor 10 in a portable electronic device (50). The gas sensor (10) operates in an ultra-low power mode when the portable electronic device (50) is inactive and the gas sensor (10) operates in a normal power mode when the portable electronic device (50) is active. The method involves storing a baseline resistance value of the gas sensor (10) in the ultra-low power mode. The gas sensor (10) transitions to a normal power mode from the ultra-power mode, when the portable electronic device (50) is active. A rate of stabilization of resistance value of the gas sensor (10) is computed in the normal power mode. A stabilized resistance value of the gas sensor (10) in the normal power mode is estimated based on the rate of stabilization of resistance value of the gas sensor (10) in the normal power mode, the baseline resistance value in the ultra-low power mode and a comparison chart of stabilized resistance values of the gas sensor (10) in the ultra-low power mode and the normal power mode.

Abstract

The invention relates to a method for identifying blooming candidates in a Lidar measurement. According to the invention, a distance-based histogram of points (P1.1 to P1.m, P2.1 to P2.j, P3.1 to P3.k, BP1 to BPn) of a point cloud generated in the Lidar measurement is established. In the histogram, clusters of points (P1.1 to P1.m, BP1 to BPn) having the same distance to a Lidar sensor (1) carrying out the Lidar measurement are identified and intensities of the points (P1.1 to P1.m, BP1 to BPn) of a cluster are evaluated. If the cluster contains points (P1.1 to P1.m), the intensities of which exceed in each case a predefined limit value, those points (BP1 to BPn) of the cluster, the intensities of which do not exceed in each case the predefined limit value and in particular fall below the predefined limit value by more than a predefined threshold value, are classified as blooming candidates.

Abstract

The invention relates to a fuel injection valve (1), particularly characterised in that the sealing of an inlet connection (7) with respect to the receiving opening (12) of a fuel distribution line (4) is improved. According to the invention, a support ring (25) is provided on the inlet port (7), which engages under the sealing ring (5) on the inlet side. The fuel injection valve (1) also has a plastic overmoulding (18) forming at least part of a valve housing (22). According to the invention, the support ring (25) engaging under the sealing ring (5) is positioned on the fuel injection valve (1) in such a way that it rests directly on an upper end face (28) of the plastic overmoulding (18) facing the sealing ring (5), so that the axial support of the sealing ring (5) is provided indirectly via the plastic overmoulding (18). The fuel injection valve is suitable, in particular, for the direct injection of fuel into a combustion chamber of a mixture-compressing external spark-ignition combustion engine.

The lower-level optimizes a variational posterior distribution of the latent variables to approximate the true posterior distribution of the EBLVM, and the higher-level optimizes the neural network parameters based on a modified SM objective as a function of the variational posterior distribution. The method may be applied to train neural networks based on EBLVMs with nonstructural assumptions.

Abstract

A system and method are disclosed for monitoring rides in a vehicle in which a driver of the vehicle picks up a rider at a pickup location and drives the rider to a drop-off destination. The system includes at least one sensor arranged in the vehicle and configured to capture sensor data during the rides, a transceiver configured to communicate with a personal electronic device of a driver of the vehicle, a non-volatile memory configured to store data; and a processor. The system captures sensor data during a ride, determines an activity index indicating an activity level within the vehicle during the ride, and stores the sensor data captured during the ride with the activity index as metadata. In response to an upload request, the system uploads sensor data depending on the activity level.
