Patent number: 11972087Abstract: A method may include generating a graphical user interface (GUI) that includes a canvas visually displaying a virtual audio environment representing an arrangement of speakers in a real-world audio environment. The virtual audio environment may include an audio object that represents sounds that are grouped together to provide a particular sound effect. The method may include obtaining, via the GUI, a selection of a particular audio object displayed in the virtual audio environment and user input relating to the audio properties associated with the selected audio object. The method may include performing an audio computation based on the user input and updating the selected audio object represented in the canvas. The method may include displaying, via the GUI, the updated audio object in the canvas.Type: GrantFiled: March 7, 2023Date of Patent: April 30, 2024Inventors: Rainer Brodersen, John Trudeau, Robert Aric Marshall, Kenneth Pearce, Michael Plitkins, Calin Pacurariu

Publication number: 20220211294Abstract: A communication device (100), for monitoring breathing, includes a microphone unit (110), a monitoring unit (120) and an output unit (130). The microphone unit receives an acoustic signal (105), which indicates the breath sounds (350) of a communication device user (102), from a surrounding area (112) of the microphone unit, and converts same into a digital input signal (114). The monitoring unit is configured to receive the digital input signal and to split the indicated breath sounds into individual breaths (124) based on an amplitude- and/or frequency-dependent pattern recognition (122) and to determine a respective breath duration (125) of a breath. The monitoring unit triggers a breath alarm state (126) of the communication device as a function of a consecutive sequence of breath durations. The output unit is configured to output an alarm output (132) indicating the breath alarm state after a triggering of the breath alarm state.Type: ApplicationFiled: January 4, 2022Publication date: July 7, 2022Inventors: Mohamed Houssem HARBI, Timo TRALAU, Michael BRODERSEN, Hauke KASTENS

Patent number: 11170622Abstract: A device includes a gas-measuring unit and a sound-measuring unit. The gas-measuring unit has a gas sensor detecting a first measured variable, and a gas analysis module determining a gas concentration from the first variable and comparing the concentration with a first threshold value, to output a first signal based thereon. The sound-measuring unit has a sound detection unit detecting a second measured variable, and a sound analysis module determining a status variable, from the second variable, indicating a noise exposure, and comparing the status variable with a second threshold value to determine a first parameter indicating a current sound level and/or determining a second parameter indicating a sound exposure accumulated over a time interval. The sound analysis module may determine the status variable, the first parameter and/or the second parameter as a function of the comparison of the gas concentration and the first threshold value.Type: GrantFiled: April 23, 2020Date of Patent: November 9, 2021Assignee: Drägerwerk AG & Co.

Patent number: 11107454Abstract: An audio processing device (100) includes a correction microphone (110), a reference microphone (120), a classification unit (130), an active noise cancellation (ANC) unit (140), and a speaker (150). The correction microphone is arranged in an area adjacent to an ear of a user of the device and picks up acoustic signals in the area and outputs same as a correction signal. The reference microphone picks up surrounding noises (124) from a surrounding area of the user and outputs same as a reference signal. The classification unit receives the reference signal and splits the reference signal corresponding to a spectrum and amplitude thereof into signal components of two or more classes and outputs a classified signal. The ANC unit receives and processes the correction signal based on the classified signal and outputs a corresponding audio signal. The speaker receives the audio signal and provides a corresponding acoustic signal output.Type: GrantFiled: March 16, 2020Date of Patent: August 31, 2021Assignee: Dräger Safety AG & Co.

Patent number: 10532233Abstract: A head simulator, for testing respirators, has a head simulator body (2) with a simulated oral aperture (6) and with a simulated oral cavity (4), which is located behind the simulated oral aperture (6) in the head simulator body. A loudspeaker (8) is arranged in the simulated oral cavity (4). An audio unit (20) is connected to the loudspeaker (8) for reproducing speech via the loudspeaker (8). The head simulator includes a simulated trachea (10), which is in connection with the simulated oral cavity (4) and opens into the simulated oral aperture (6). An air delivery device (30) is provided, which can be operated to allow air to flow through the simulated trachea (10) and the simulated oral aperture (6).Type: GrantFiled: December 7, 2017Date of Patent: January 14, 2020Assignee: Dräger Safety AG & Co.

Patent number: 5452308Abstract: A method for monitoring symmetrical two-wire bus lines and two-wire bus interfaces and a device for carrying out the method provides pulse weighting of low to high transitions or high to low transitions of the two wires operated in phase opposition of a two-wire bus line. The pulse chains thus obtained are used for step sequencing. In each case, one multistep shift function which is assigned to the first bus wire, is supplied with a first, constant logic read in state and can be reset to a second logic state in all-step fashion and, for all-step resetting of a similar second multistep shift function assigned to the second bus while, and vice versa, the step last achieved for each multistep shift function characterizing the respective fault state of the other bus wire. The pulse weighting is achieved by differentiation or high-pass filtering or by pulse generation controlled by state transition.Type: GrantFiled: April 6, 1993Date of Patent: September 19, 1995Assignee: Mercedes-Benz AGInventors: Detlef Kaminski, Thilo Kuhner, Wolfgang Kremer, Bernd Haussler, Max Reeb, Rolf Adomat, Michael Brodersen, Alexander Dorr, Herbert Fiessinger
