Publication number: 20250064620Abstract: A nasal dilator for treating breathing problem is provided, which includes a hollow nasal dilator body and a one-way flow resistance unit. The hollow nasal dilator body has a first end opening and a second end opening opposing the first end opening. The hollow nasal dilator body longitudinally extends from the first end opening to the second end opening and being adapted for insertion into a user's nostril with the second end opening placed within the user's nasal passage so that the hollow nasal dilator body supports and dilates the nasal passage. The one-way flow resistance unit is assembled to the hollow nasal dilator body and in proximity to the first end opening and away from the second end opening. The one-way flow resistance unit creates an exhalation flow resistance higher than an inhalation flow resistance such that an expiratory positive airway pressure is generated within the nasal passage.Type: ApplicationFiled: August 31, 2022Publication date: February 27, 2025Applicant: Somnics, Inc.Inventors: Chung-Chu CHEN, Chih-Jung LEE, Chieh-Neng YOUNG, Tung-Ming YU

Publication number: 20240377905Abstract: Embodiments of the present disclosure provide systems and methods to prevent false triggering of the touchpad buttons associated with a touchpad. The false touchpad button mitigation system and method uses executable logic that upon detection of a button press event, determines whether touchpad data is currently being received from the touchpad, and when no touchpad data is currently being received, inhibit the button press event from being processed by an Information Handling System (HIS). Touchpad data refers to data generated by a touchpad when a user's finger is touching the touchpad. Thus, if the user is not actively touching the touchpad, the false button press event may be blocked by the executable logic.Type: ApplicationFiled: May 9, 2023Publication date: November 14, 2024Applicant: Dell Products, L.P.Inventors: Tao-Peng Chu, Chen Hsin Chang, Yi-Chung Chu, Shao-Hung Yu

Patent number: 12143783Abstract: A system configured to perform sound source localization (SSL) using reflection detection is provided. A device processes audio data from multiple microphones to determine timing information corresponding to sound sources. For example, the device may determine cross-correlation data for each microphone pair, determine autocorrelation data for each microphone, and then use the autocorrelation data and the cross-correlation data to calculate quality factors.

Patent number: 12009269Abstract: To provide more test data during the manufacture of non-volatile memories and other integrated circuits, machine learning is used to generate virtual test values. Virtual test results are interpolated for one set of tests for devices on which the test is not performed based on correlations with other sets of tests. In one example, machine learning determines a correlation study between bad block values determined at die sort and photo-limited yield (PLY) values determined inline during processing. The correlation can be applied to interpolate virtual inline PLY data for all of the memory dies, allowing for more rapid feedback on the processing parameters for manufacturing the memory dies and making the manufacturing process more efficient and accurate. In another set of embodiments, the machine learning is used to extrapolate limited metrology (e.g., critical dimension) test data to all of the memory die through interpolated virtual metrology data values.Type: GrantFiled: April 21, 2022Date of Patent: June 11, 2024Assignee: SanDisk Technologies LLCInventors: Cheng-Chung Chu, Masaaki Higashitani, Yusuke Ikawa, Seyyed Ehsan Esfahani Rashidi, Kei Samura, Tsuyoshi Sendoda, Yanli Zhang

Publication number: 20240142563Abstract: A method and a system for wireless positioning are provided. Multiple received signal strengths corresponding to multiple wireless access points are measured by a user device. The received signal strengths include multiple first received signal strengths. A reference positioning position is obtained according to positioning reference information provided by the user device. A first positioning position based on the first received signal strengths is obtained. The reference positioning position is compared with the first positioning position. In response to the distance between the reference positioning position and the first positioning position being greater than a tolerance value, at least one of the first received signal strengths is excluded from the multiple received signal strengths, so as to obtain multiple filtered received signal strengths. A user position of the user device is obtained according to the filtered received signal strengths.Type: ApplicationFiled: February 5, 2023Publication date: May 2, 2024Applicant: Wistron CorporationInventors: Kuo-Chung Chu, CHIEN-MING CHU

Patent number: 11950062Abstract: A system configured to improve sound source localization (SSL) processing by reducing a number of direction vectors and grouping the direction vectors into direction cells is provided. The system performs clustering to generate a smaller set of direction vectors included in a delay-direction codebook, reducing a size of the codebook to the number of unique delay vectors. In addition, the system groups the direction vectors into direction cells having a regular structure (e.g., predetermined uniformity and/or symmetry), which simplifies SSL processing and results in a substantial reduction in computational cost. The system may also select between multiple codebooks and/or dynamically adjust the codebook to compensate for changes to the microphone array. For example, a device with a microphone array fixed to a display that can tilt may adjust the codebook based on a tilt angle of the display to improve accuracy.Type: GrantFiled: March 31, 2022Date of Patent: April 2, 2024Assignee: Amazon Technologies, Inc.Inventors: Wai Chung Chu, Carlo Murgia

Patent number: 11915698Abstract: A system configured to improve track selection while performing audio type detection using sound source localization (SSL) data is provided. A device processes audio data representing sounds from multiple sound sources to determine SSL data that distinguishes between each of the sound sources. The system detects an acoustic event and performs SSL track selection to select the sound source that corresponds to the acoustic event based on input features. To improve SSL track selection, the system detects current conditions of the environment and determines adaptive weight values that vary based on the current conditions, such as a noise level of the environment, whether playback is detected, whether the device is located near one or more walls, etc. By adjusting the adaptive weight values, the system improves an accuracy of the SSL track selection by prioritizing the input features that are most predictive during the current conditions.Type: GrantFiled: September 29, 2021Date of Patent: February 27, 2024Assignee: Amazon Technologies, Inc.Inventors: Borham Lee, Wai Chung Chu

Patent number: 11749294Abstract: A system configured to perform directional speech separation. The system may dynamically associate direction-of-arrivals with one or more audio sources in order to generate output audio data that separates each of the audio sources. The system identifies a target direction for each audio source, dynamically determines directions that are correlated with the target direction, and generates output signals for each audio source. The system may associate individual frequency bands with specific directions based on a time delay detected by two or more microphones. The system may determine a cross-correlation between each direction and the target direction and select directions with strong correlation. The system may generate time-frequency mask data indicating frequency bands corresponding to the directions associated with a particular audio source. Using the mask data, the system generates output audio data specific to the audio source, resulting in directional speech separation between different audio sources.Type: GrantFiled: August 21, 2020Date of Patent: September 5, 2023Assignee: Amazon Technologies, Inc.Inventor: Wai Chung Chu
