  • Publication number: 20240099639
    Abstract: A method of computing a heart rate value compensates for noise derived from the subject, the sensor, the transmission, and/or other variables that can lead to false R-peak detection or missed R-peak detection. The method computes an updated heart rate based on a window of approximately ten seconds of digitized ECG readings broadcast from a sensor. A new value is calculated approximately every second such that the window of ECG readings overlaps considerably between consecutive calculations. The method compensates for noisy data by discarding heart rate samples that differ by more than a threshold amount from a previously calculated heart rate value. The threshold is adjusted based on a standard deviation of differences between heart rate samples. Prior to calculating a heart rate value, a forward-looking, pre-filter logic may be applied in situations where the raw data has an extremely low signal-to-noise ratio.

  • Publication number: 20240074158
    Abstract: A variety of applications can include an apparatus having a memory device in which, during fabrication of the memory device, processing a dielectric isolation region about an active area of a memory cell is controlled to provide enhanced electric isolation of a data line contact to the memory cell with respect to a cell contact to the memory cell. A portion of the dielectric isolation region can be recessed, creating a corner between the dielectric isolation region and a conductive region, where the conductive region is material for the active area. The corner can be filled with a dielectric material and the data line contact can be formed contacting the dielectric material and coupled to the conductive region. The cell contact can be formed to the memory cell contacting the dielectric material such that the dielectric material is between the cell contact and the data line contact.

  • Publication number: 20240002781
    Abstract: Described herein is a method for encapsulating single cells using alternating current electrospray technology in tip streaming mode. The encapsulation efficiency is over 80% and natural (alginate, collagen) and synthetic (NorHA) hydrogels and various cell types can be used. The encapsulated cells can be implanted and are protected from the host's immune response. In addition, the coating allows better tissue growth in laboratory cell cultures with a conformal mechanical support that allows molecular and nutrient transport.

  • Patent number: 11854116
    Abstract: Techniques for masking images based on a particular task are described. A system masks portions of an image that are not relevant to a particular task, thus, reducing the amount of data used by applications for image processing tasks. For example, images to be processed using a hair color classification model are masked so that only portions that show the person's hair are available for the model to analyze. The system configures different masker components to mask images for different tasks. A masker component can be implemented at a user device to mask images prior to sending to an application/task-specific model.

  • Patent number: 11626107
    Abstract: Devices and techniques are generally described for inference reduction in natural language processing using semantic similarity-based caching. In various examples, first automatic speech recognition (ASR) data representing a first natural language input may be determined. A cache may be searched using the first ASR data. A first skill associated with the first ASR data may be determined from the cache. In some examples, first intent data representing a semantic interpretation of the first natural language input data may be determined by using a first natural language process associated with the first skill.

  • Publication number: 20230068798
    Abstract: A system can operate a speech-controlled device to perform active speaker detection to detect an utterance using image data showing a user speaking the utterance. This enables the device to perform utterance detection using the image data and/or determine which user is speaking the utterance. To perform active speaker detection, the device processes the image data to determine expression parameters associated with the user's face and generates facial measurements based on the expression parameters. For example, the device can use the expression parameters to generate a 3D model including an agnostic facial representation and determine a mouth aspect ratio by measuring a mouth height and a mouth width of the agnostic facial representation. As the mouth aspect ratio changes when the user is speaking, the device can determine that the user is speaking and/or detect an utterance based on an amount of variation of the mouth aspect ratio.

    Abstract: Devices and techniques are generally described for three dimensional mesh generation. In various examples, first two-dimensional (2D) image data representing a human may be received. In various further examples, bounding box data identifying a location of the human in the first 2D image data and joint data identifying locations of joints of the human may be received. Second 2D image data representing a cropped portion of the human may be generated using the bounding box data and the joint data. A three-dimensional (3D) mesh prediction model may be used to determine a pose, a shape, and a projection matrix for the human. The 3D mesh prediction model may be used to determine a transformed projection matrix for the portion of the human represented in the second 2D image data.
