  • Publication number: 20190195849
    Abstract: A VOC detecting and warning method is provided. Firstly, an actuating-and-sensing module having a gas transportation actuator and a gas sensor is provided. Then, the gas transportation actuator guides a specified amount of gas to the gas sensor for obtaining plural monitored values, each of which is generated according to a result of detecting volatile organic compounds of the gas in each monitoring time interval by the gas sensor. All the monitored values obtained in a unit time period are added together, so that an accumulated comparison value is obtained. If the accumulated comparison value is determined greater than an injury threshold defined according to the VOC inhalation amount affecting the health of a human body, the actuating-and-sensing module issues a warning notification to notify the user to take protective measures.

  • Publication number: 20190151639
    Abstract: A blood glucose monitoring and controlling system includes a detecting device and a liquid supplying device. The detecting device includes a first microneedle patch, a liquid pumping actuator, a sensor and a monitoring and controlling chip. The liquid supplying device includes a second microneedle patch, a liquid supplying actuator, a liquid supplying chamber and a liquid supplying and controlling chip. The detecting device is used to measure the blood glucose level of the user, and the liquid supplying device is used to supply insulin liquid. While the detecting device measures that the blood glucose level of the user is abnormal, the liquid supplying device is actuated to inject the insulin liquid into the user's body, thereby stabilizing the user's blood glucose level constantly.

  • Patent number: 10297455
    Abstract: A method for forming a gate oxide layer on a substrate is provided, in which a region of the substrate is defined out by a shallow trench isolation (STI) structure. An oxide layer covers over the substrate and a mask layer with an opening to expose oxide layer corresponding to the region with an interface edge of the STI structure. The method includes forming a silicon spacer on a sidewall of the opening. A cleaning process is performed through the opening to expose the substrate at the region. An oxidation process is performed on the substrate at the region to form the gate oxide layer, wherein the silicon spacer is also oxidized to merge to an edge of the gate oxide layer.

  • Patent number: 10182205
    Abstract: A method for communication includes establishing multiple communication links over a packet network between a server and plurality of client computers that are to participate in a video teleconference. The client computers may also create secondary communication links that function similarly to links between the server and client computers. The server receives from the client computers uplink audio packets and uplink video packets, which respectively contain audio and video data captured by each of the client computers. The server mixes the audio data from the uplink audio packets so as to create respective streams of mixed audio data for transmission to the client computers and transmits to the client computers downlink audio packets containing the respective streams of mixed audio data. The server relays the video data to the client computers in downlink video packets. The client computers receive and synchronize the video data with the mixed audio data.
