  • Publication number: 20240027623
    Abstract: The disclosure relates to a method for determining a profile section of an object and/or space by means of a 2D laser scanner having a laser rangefinder, including: recording mutually assignable distance measurement values and distance measurement directions by means of the laser rangefinder in a measuring plane traversed radially by a laser beam of the laser rangefinder, determining the profile section, from the distance measurement values and distance measurement directions, determining an angle of inclination of the measuring plane with respect to a reference plane, and correcting the profile section using the angle of inclination of the measuring plane. According to the disclosure, the angle of inclination of the measuring plane is determined by using the laser rangefinder. The disclosure also relates to a 2D laser scanner and to a system.

  • Publication number: 20230362559
    Abstract: An audio processing path receives an audio signal from a microphone of an ear-wearable device and reproduces the audio signal at a receiver that is placed within an ear of a user. A deep neural network (DNN) is coupled to the audio processing path that performs speech enhancement on the audio signal. An audio feature detector is operable to detect an audio change via the processing path that triggers a change of state of the DNN. The change of state affects resource consumption by the DNN. The change of state is applied to the DNN, and the DNN performs the speech enhancement in the changed state.

  • Publication number: 20230292074
    Abstract: An ear-wearable device stores a plurality of neural network data objects each defining a respective neural network. A sound signal received from a microphone of the ear-wearable device is digitized. An ambient environment of the digitized sound signal is classified into one of a plurality of classifications. Based on the classification, one of the neural network data objects is selected to enhance the digitized sound signal. An analog signal is formed based on the enhanced digitized sound signal. The analog signal is reproduced via a receiver of the ear-wearable device.

  • Publication number: 20230276182
    Abstract: A system includes a mobile device that receives an audio signal from a microphone of the mobile device. The mobile device processes the audio signal via a neural network to obtain a speech-enhanced audio signal. The system includes an ear-wearable device comprising a data interface operable to communicate with the external data interface of the mobile device. The ear-wearable device includes an audio processing path coupled to the data interface and is operable to receive the speech-enhanced audio signal and reproduce the speech-enhanced audio in an ear of a user.

  • Patent number: 11539889
    Abstract: The disclosure relates to a method for the noise optimization of a camera, in particular a handheld thermal imaging camera. Images are captured by means of the camera in at least one method step; at least one movement characteristic variable is detected by means of at least one sensor unit of the camera in at least one method step; and image data of captured images is averaged by means of a computing unit of the camera in at least one method step. At least a number of images to be averaged are determined by means of the computing unit of the camera at least on the basis of an intensity of the detected movement characteristic variable, in particular a change rate, in at least one method step.

  • Patent number: 10911043
    Abstract: A device and a method for switching over a semiconductor switch with a switching signal acting on a control connection of the semiconductor switch, the switching signal being switched over as a response to registering a switchover of an activation signal; a down time being ascertained between the start of the switchover of the switching signal and the switchover of the semiconductor switch; the switchover of the semiconductor switch being delayed by a waiting period, for example by delaying the output of the switching signal and/or changing the signal level, so that an actual switching time, corresponding to a setpoint switching time, between the registration of the switchover of the activation signal and the switchover of the semiconductor switch is obtained.
