Publication number: 20230247356Abstract: A frequency-dependent signal limiter using a paired combination of a bandpass filter (or “selection filter”) and an attenuating equalizing filter (or “cutting filter”) limit the amount of distortion generated by an audio output device in an acoustic rendering system. A bank of one or more of these pairs in series can be used to limit selected frequencies identified as primary causes of distortion in the audio output device to specified levels that avoid distortion.Type: ApplicationFiled: January 28, 2022Publication date: August 3, 2023Inventors: Christopher Ian BOROWSKI, Eric MIDDLETON, Chun Beng GOH, Jani Samuli KUIVALAINEN, Dana William BOURKE, Kevin Juho VENALAINEN

Patent number: 11245985Abstract: A host device is connected via universal serial bus (USB) connections to one or more external devices with respective speakers. The host device synchronizes playback of audio through the speakers of the USB-connected external devices by requiring devices to implement a deterministic latency between receipt of a start playback request, and requiring devices to slave their audio clocks to USB start-of-frame tokens, and determining a buffered start time for starting data transmission to the respective USB devices. The buffered time equates to the current time of the USB host plus an additional time buffer. The host device waits until the buffered start time, and then starts transmitting the audio stream to the external devices, which, in turn, begin playing the audio data on the next available clock cycle, frame, or microframe.Type: GrantFiled: March 27, 2019Date of Patent: February 8, 2022Assignee: Microsoft Technology Licensing, LLCInventors: Christopher Ian Borowski, Kevin Juho Venalainen

Patent number: 10739993Abstract: A computing device includes a touch-sensitive user interface configured to present a unified collaborative session for two or more users, and an authentication module configured to simultaneously identify and authenticate multiple users physically co-located within a collaborative environment, allowing each of the multiple users to interact with the touch-sensitive user interface. A content module is configured to simultaneously provide one or more content portals within the unified collaborative session for each authenticated user. Each content portal is configured to enable an authenticated user to access, retrieve, and present user-owned content files within the unified collaborative session. In this way, multiple users may simultaneously access, retrieve, and present their own content files on a single computing device.Type: GrantFiled: January 19, 2017Date of Patent: August 11, 2020Assignee: Microsoft Technology Licensing, LLCInventors: Stanley T. Birchfield, Avronil Bhattacharjee, Kevin Juho Venalainen, Arthur Baker

Patent number: 10649060Abstract: Techniques are described herein that are capable of performing sound source localization (SSL) confidence estimation using machine learning. An SSL operation is performed with regard to a sound to determine an SSL direction estimate and an SSL-based confidence associated with the SSL direction estimate based at least in part on a multi-channel representation of the sound. The SSL direction estimate indicates an estimated direction from which the sound is received. The SSL-based confidence indicates an estimated probability that the sound is received from the estimated direction. The multi-channel representation includes representations of the sound that are detected by respective sensors (e.g., microphones). Additional characteristic(s) of the sound are automatically determined.Type: GrantFiled: July 24, 2017Date of Patent: May 12, 2020Assignee: Microsoft Technology Licensing, LLCInventor: Kevin Juho Venalainen

Patent number: 10313798Abstract: An electronic device with directional MEMS microphone assembly is provided, including a MEMS microphone capsule with a PCB affixed thereto, and a housing affixed to the PCB. The microphone assembly includes a first internal port and a second internal port through the PCB, wherein the first and second internal ports fluidically communicate with the MEMS microphone capsule. The microphone assembly further includes first and second external ports through the housing, wherein the first external port is offset from the first internal port in an offset direction perpendicular to a thickness direction of the microphone assembly. The microphone assembly further includes first and second cavities located between the PCB and the housing, wherein the first cavity fluidically communicates with the first internal port and the first external port, and the second cavity fluidically communicates with the second internal port and the second external port.Type: GrantFiled: May 26, 2017Date of Patent: June 4, 2019Assignee: MICROSOFT TECHNOLOGY LICENSING, LLCInventors: Kevin Juho Venalainen, Brian W. Aznoe, Dana William Bourke

Patent number: 10283135Abstract: Suppression of tapping noise caused by tapping an acoustically coupled touchscreen. When a tapping event is detected on the touchscreen, a tapping noise suppressor is alerted of the event, and responds by at least temporarily mitigating the tapping noise in the audio stream. The suppression occurs temporarily for at least part of the duration of surge in audio levels that occurs as a result of the tapping event, and in a manner that reduces the psychoacoustic impact on the conversation. Suppression may be performed by first placing the tapping noise suppressors in an alert mode when a tapping event occurs. The tapping noise suppressor then monitors the audio stream generated by the microphone for the beginning of the tapping event—which will be represented in the form of a surge in volume. The tapping noise suppressor then temporarily applies the suppression window.Type: GrantFiled: December 22, 2016Date of Patent: May 7, 2019Assignee: Microsoft Technology Licensing, LLCInventors: Kevin Juho Venalainen, Sylvain Angrignon
