Abstract: A signal processing method for cochlear implant is performed by a speech processor and comprises a noise reduction stage and a signal compression stage. The noise reduction stage can efficiently reduce noise in a electrical speech signal of a normal speech. The signal compression stage can perform good signal compression to enhance signals to stimulate cochlear nerves of a patient with hearing loss. The patient who uses a cochlear implant performing the signal processing method of the present disclosure can accurately hear normal speech.

Abstract: A sound localization system includes a multi-mic sound collector and a computing device. The multi-mic sound collector includes a carrier and a plurality of sound receivers removably attached to the sound receivers. The computing device includes a data communicator, a synchronizer, and a processor. The data communicator receives preprocessed audio data from the multi-mic sound collector. The synchronizer synchronizes the preprocessed audio data. The processor analyzes the synchronized audio data to identify and localize a target audio feature. A sound localization method of the sound localization system is also provided. The present invention facilitates monitoring of the functioning or physiological signs of a monitored subject and allows early detection and diagnosis of abnormalities or diseases.

Abstract: A heart rate detection method for calculating heart rate using heart sound from auscultation positions identified by a statistical approach utilizes a down-sampling and filtering process to acquire samples of heart sound from multiple auscultation positions of multiple testees and calculate heart rate with the samples, records time for calculating heart rate from each auscultation position of each testee and record the same from electrocardiogram, calculates a mean error and a standard deviation of the time to identify the auscultation positions allowing faster speed in heart rate detection, and applies a Bland-Altman difference plot and both a coefficient of determination and a Pearson's correlation coefficient to determine the degree of consistency and correlation of the heart rate measured from the multiple auscultation positions to identify the auscultation positions allowing generation of precise heart rate.

Abstract: A system for recognizing physiological sound comprises a receiving module, a feature extracting module, a classifier, and a comparing module. A method for recognizing physiological sound comprises receiving a physiological sound by the receiving module; extracting at least one feature from the physiological sound by the feature extraction module; classifying the at least one feature to identify at least one category by a classifier; and comparing the at least one category with a normal physiological sound and/or an abnormal physiological sound by the comparing module for evaluating a risk of disease. The method and system for recognizing physiological sound can precisely identify the specific physiological sound and exclude the noise.

The first chip includes a separating unit and a reacting unit. The separating unit separates the target object from a non-target object in the fluid. The reacting unit enables the fluid having separated out the non-target object to react with a reagent. The signal source provides a signal passing through the fluid having reacted with the reagent. The second chip disposed at one side of the first chip includes a signal transducing element and a processing unit. The signal transducing element receives the signal passing through the fluid and outputs an electronic signal corresponding to the input signal. The processing unit acquires the concentration of the target object according to the electronic signal.
