    摘要: Methods and systems are disclosed for determining whether a patient is a responder to cardiac resynchronization therapy. The beginning and ending of the intrinsic ventricular depolarization are determined through signals measured from one or more electrodes implanted in the patient's heart. An interval between the beginning and ending of the intrinsic ventricular depolarization is computed and is compared to a threshold. The threshold may be determined empirically. The pacing parameters of a heart stimulation device, such as a pacemaker, may then be configured, for example, by setting the paced atrio-ventricular delay based on whether the patient responds positively to cardiac resynchronization therapy.

    摘要: The invention provides a system for calibrating phase and gain mismatches of an array microphone. The array microphone is installed in a voice interface device and comprises a plurality of microphones. The system comprises a loudspeaker and a computing equipment. The loudspeaker plays a segment of sound to be received by the array microphone. The computing equipment controlls the voice interface device which converts the segment of sound to a plurality of audio signals with the microphones of the array microphone, records the audio signals outputted by the voice interface device at bypass mode without any signal processing, calculates delays between the audio signals, and instructs the voice interface device to adjust phase mismatches between the audio signals according to the delays.

    摘要: Systems and methods for authenticating Internet-of-Things devices are disclosed. According to certain embodiments, the method includes broadcasting, via a communication network, a connection token. The method also includes receiving, via the communication network, a pairing request from a second device receiving the connection token. The method also includes providing, via the communication network, identification information of the first device to the second device. The method further includes receiving, from the second device, an authentication token generated based on the identification information of the first device.
