  • Patent number: 12318274
    Abstract: A method of making an absorbent composite that includes a first fabric, a second fabric, and particles positioned between the two fabrics and absorbent articles made from the absorbent composite. The particles are secured between the two fabric using adhesive, thermal plastic or combinations thereof. The fabrics are bonded together in a manner that limits particle movement between the fabrics. The bond pattern may define pockets or other shapes. In applications in which the bond pattern forms pockets, the particles may be positioned in the pockets. The particles may be SAP particles or other particles with advantageous properties.

  • Publication number: 20240374897
    Abstract: The present disclosure provides methods and systems for treating affective disorders such as depression and/or anxiety and/or related disorders. Closed-loop therapy is performed with a neurostimulator that records electroencephalographic signals from neural activity associated with symptoms of a neuropsychiatric disorder and delivers electrical stimulation when pre-specified patterns of neural activity associated with a symptom are detected. Methods are also disclosed for mapping the brain of a patient to optimize placement of electrodes for detecting neural activity associated with symptoms of a neuropsychiatric disorder and to optimize placement of electrodes for delivery of electrical stimulation. Methods of monitoring and evaluating the effects of electrical stimulation on clinical symptoms and status are also provided.

  • Publication number: 20240366157
    Abstract: Methods, devices, and systems for assisting individuals with communication are provided. In particular, methods, devices, and systems are provided for decoding words and sentences directly from neural activity of an individual. Cortical activity from a region of the brain involved in speech processing is recorded while an individual attempts to say or spell out words. Deep learning computational models are used to detect and classify words from the recorded brain activity. Decoding of speech from brain activity is aided by use of a language model that predicts how likely certain sequences of words are to occur. In addition, decoding of attempted non-speech motor movements from neural activity can be used to further assist communication. This neurotechnology can be used to restore communication to patients who have lost the ability to speak and has the potential to improve autonomy and quality of life.

  • Patent number: 11361865
    Abstract: A computer aided medical method includes the following steps. An initial symptom of a patient and context information is collected through an interaction interface. Actions in a series are sequentially generated according to the candidate prediction models and the initial symptom. Each of the actions corresponds to one of the inquiry actions or one of the disease prediction actions. If the latest one of the sequential actions corresponds to one of the disease prediction actions, potential disease predictions are generated in a first ranking evaluated by the candidate prediction models. The first ranking is adjusted into a second ranking according to the context information. A result prediction corresponding to the potential disease predictions is generated in the second ranking.

  • Publication number: 20220068297
    Abstract: A system and method provides for false wake abatement. For instance, an audio energy detection controller opens a keyword detection window in response to a detected audio input level reaching a threshold and a keyword detector detects a keyword in response to a detected audio input corresponding to a keyword signature. In response to both a keyword being detected and the detected audio input level indicating a near field source of the speech, a device may be triggered to awaken. In this manner, the incidence of false awakenings due to keywords spoken by proximate third parties is ameliorated.
