  • Patent number: 11328161
    Abstract: A system for identifying and timing an athlete during a timed sporting event. The athlete is timed using image recognition technology in which one or more images of the athlete taken during the sporting event by a camera (106a, 106b, or 106c) is time-stamped to generate a finish time for the athlete. The athlete is identified by comparing one of the images taken during the sporting event with a profile image of the athlete.

  • Patent number: 11327710
    Abstract: A computer-implemented method for audio signal processing includes analyzing a foreground audio signal to determine metrics corresponding to audio slices of the foreground audio signal. Each such metric indicates a value for an audio property of a respective audio slice. The method further includes computing a total metric for an audio slice as a function of a set of the metrics corresponding to a set of the audio slices including the audio slice. The method further includes adding a key frame to a track based on the total metric. The track includes the foreground audio signal and a background audio signal, and a location of the key frame corresponds to a location of the audio slice on the track. The key frame indicates a change to the audio property of the background audio signal at the location on the track, and the key frame is utilizable for audio ducking.

  • Patent number: 11322165
    Abstract: When compressing an HOA data frame representation, a gain control (15, 151) is applied for each channel signal before it is perceptually encoded (16). The gain values are transferred in a differential manner as side information. However, for starting decoding of such streamed compressed HOA data frame representation absolute gain values are required, which should be coded with a minimum number of bits. For determining such lowest integer number (?e) of bits the HOA data frame representation (C(k)) is rendered in spatial domain to virtual loudspeaker signals lying on a unit sphere, followed by normalisation of the HOA data frame representation (C(k)). Then the lowest integer number of bits is set to ?e=?log2(?log2(?{square root over (KMAX)}·O)?+1)?.

    Abstract: Auditory communication devices and related methods are described herein. An example auditory communication device can include a microphone configured to collect acoustic energy and convert the collected acoustic energy into an audio signal, a processor operably coupled to the microphone, and a memory operably coupled to the processor. The processor can be configured to receive the audio signal from the microphone, create a time-frequency (T-F) representation of the audio signal, classify each of a plurality of T-F units into one of N discrete categories, and attenuate the T-F representation of the audio signal. A respective level of attenuation for each of the T-F units is determined by its respective classification. The processor can be further configured to create a synthesized signal from the attenuated T-F representation of the audio signal.

  • Patent number: 11209979
    Abstract: Techniques for obfuscating selection of an option during user-input of sensitive information, involving displaying several targets, such as via a virtual keyboard, on a device display, where each target corresponds to one of multiple options. When a first visual indication of a current user target moves to a first target in response to a first user navigation input, an obfuscation system can concurrently or soon thereafter move a second visual indication of a first distractor target to another target. The current user target is thus obfuscated as two different visual indicators move through the targets.

  • Patent number: 11200023
    Abstract: Apparatus and methods for processing an audio signal. The apparatus may include a digital signal processor (“DSP”) configured to receive an audio signal from a vehicular audio signal line. The audio signal may include a flat component and a compensatory component. The flat component may correspond to the audio signal in a state before combination with the compensatory component. The compensatory component may include an OEM EQ component. The apparatus may include a microprocessor in electronic communication with the DSP. The microprocessor may be configured to retrieve from the memory a restorative signal component. The microprocessor may be configured to instruct the DSP to apply the restorative signal component to the audio signal to reduce the audio signal to the flat component.

  • Patent number: 11199457
    Abstract: An measuring instrument for a physiological heat quantity emitted from a human body includes a heat flux sensor, and a calculator. The heat flux sensor includes a sensor main body portion and a moisture absorbing member. The sensor main body portion has multiple through holes penetrating through the sensor main body portion from a first surface to a second surface. The sensor main body portion is disposed on a human body such that the first surface is adjacent to the human body when in use, and outputs a sensor signal according to a heat flux passing through the sensor main body portion from the first surface toward the second surface. The moisture absorbing member is stacked on the second surface of the sensor main body portion. The calculator calculates the physiological heat quantity based on the sensor signal.

  • Patent number: 11197096
    Abstract: Systems and methods for media playback via a media playback system include detecting a first wake word via a first network microphone device of a first playback device, detecting a second wake word via a second network microphone device of a second playback device, and forming a bonded zone that includes the first playback device and the second playback device. In response to detecting the first wake word, a first voice first voice utterance following the first wake word is transmitted a first voice assistant service. In response to detecting the second wake word, a second voice utterance following the second wake word is transmitted to a second voice assistant service. Requested media content received from the first and/or second voice assistant service is played back via the first playback device and the second playback device in synchrony with one another.

  • Patent number: 11197068
    Abstract: An electronic device stores a shared playback queue for the shared playback session, the shared playback queue comprising one or more media content items, including a first media content item requested by a first user. While the shared playback queue includes the first media content item, the device receives a second request, from a second user, to add a second media content item to the shared playback queue. The device determines an order of the shared playback queue based at least in part on the musical preferences indicated in a profile of a third user of the plurality of users participating in the shared playback session. The device provides, for playback in the shared playback session, the first media content item and the second media content item based on the order of the shared playback queue.

  • Patent number: 11190896
    Abstract: An audio system and a method of using the audio system to determine an interaural head-related transfer function (HRTF) parameter, are described. The audio system can generate binaural recordings using microphones that are worn by a user in everyday scenarios. The audio system can measure interaural parameter values of selected segments of the recordings, and the measurements can be accumulated over time. The interaural HRTF parameter can be estimated based on the measurements. The interaural HRTF parameter can be used to adapt a generic HRTF to generate an individualized HRTF for the user. Other aspects are also described and claimed.
