  • Publication number: 20150182132
    Abstract: A system that continuously monitors cardiovascular health using an electrocardiography (ECG) source synchronized to an optical (PPG) source, without requiring invasive techniques or ongoing, large-scale external scanning procedures. The system includes an ECG signal source with electrodes contacting the skin, which generates a first set of information, and a mobile device having a camera which acts as a PPG signal source that generates a second set of information. Together with the mobile device's processor, configured to receive and process the first and second sets of information, from which the time differential of the heart beat pulmonary pressure wave can be calculated, continuous data related to cardiovascular health markers such as arterial stiffness can be determined. Variations of the ECG source may include a chest strap, a plug-in adaptor for the mobile device, or electrodes built into the mobile device.

  • Publication number: 20140357050
    Abstract: A method of forming an isolation structure and a through silicon via includes the following steps. First, at least a first trench and at least a second trench are formed in the substrate by a single etch step. Then, an insulating layer is formed to simultaneously fill up the first trench and cover a sidewall and a bottom of the second trench. After that, a conductive layer is formed to fill in the second trench. Subsequently, the insulating layer and the conductive layer on a front side of the substrate are removed. Later, a back side of the substrate is thinned to expose the conductive layer in the second trench. The insulating layer in the first trench serves as an insulating filling, and the insulating layer on the sidewall of the second trench serves as a liner of the through silicon via.
