  • Patent number: 11222653
    Abstract: The present invention relates to a system and a method for determining a stroke based on a voice analysis. According to the present invention, voice data of subjects are collected to extract and analyze voice onset times to determine stroke patients based on voices. The system for determining a stroke generates and collects voice data from test subjects reading a predetermined word that includes a plosive sound. The system for determining a stroke extracts and calculates voice onset times from the voice data to calculate probability parameters for the voice onset times of each of a normal group and a stroke patient group. The system for determining a stroke uses a set of probability parameters to determine an integration section, and calculates probabilities of being in the normal group and the stroke patient group. The system for determining a stroke applies the calculated probabilities to the Bayes theorem to determine whether the subjects are stroke patients.

  • Patent number: 6393024
    Abstract: An ATM switch network with an expansible optical ring, in which each switch forms several paths with a vertical ring, a horizontal ring and an expansible ring. The network has a large-capacity and a small switching interval, minimizing cell delay deviation and rendering the network suitable for high-speed multimedia service. A group switch node is formed by grouping the switches forming the vertical and horizontal rings, thereby enhancing reliability within a transmission interval by bisecting the wavelength division multiplexed logical paths and by using two optical lines. The network discriminates between I/O terminals for matching data having a low-speed small capacity and wavelength division I/O terminals for matching data having a high-speed large capacity. By using a node's I/O terminals, the network interconnects nodes via wavelength division multiplexing optical lines, thereby forming an automatic adaptive network.
