  • 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.
