  • Publication number: 20220013528
    Abstract: A semiconductor device, a method of fabricating the semiconductor device and a memory are disclosed. In the provided semiconductor device, bit line contact plugs partially reside on insulating material layers in gate trenches in active areas and thus can come into sufficient contact with the active areas. This ensures good electrical transmission between the bit line contact plugs and the active areas even when there are internal voids in the bit line contact plugs. Such bit line contact plugs allowed to contain internal voids can be fabricated in an easier and faster manner, thus allowing a significantly enhanced memory fabrication throughput.

  • Patent number: 11151720
    Abstract: The present invention provides a physiological information detection method for calculating a physiological value by using changes of a dynamic image. The detection method includes: acquiring detection data from a gray-scale value of the dynamic image, and transforming the detection data into frequency data. The detection method further includes: determining whether the frequency data meet a preset condition, and using a transformation model of a corresponding transformation combination accordingly to transform the frequency data into a physiological value. The present invention further provides a physiological information detection device applying the detection method.

  • Patent number: 10835135
    Abstract: A non-contact heartbeat rate measurement system includes an image sensor, a target region selecting module, a heartbeat signal calculating module, a spectrum analyzing module, a vibration detecting module, a heartbeat peak selecting module. When a signal quality indicator is greater than a threshold value, and a first peak with global highest signal intensity in a heartbeat spectrum is similar to a face vibration frequency, the heartbeat peak selecting module selects a second peak with local highest signal intensity from a part frequency band of the heartbeat spectrum as an output heartbeat frequency. A non-contact heartbeat rate measurement method and an apparatus are disclosed herein.

  • Publication number: 20190209083
    Abstract: A monitoring system for infant includes image sensors, a face region determination module, a human face identification module, a non-contact physiological information measurement module and a physiological information determination module. The image sensors are configured to capture images consecutively. The face region determination module is configured to determine whether images include a face region. When not include, the face region determination module outputs a first warning information and when include, the human face identification module is configured to identify a monitored person in images to extract the historical information. The non-contact physiological information measurement module is configured to calculate color difference of each pixel of the face region, output heartbeat waveform and calculate physiological information.
