  • Publication number: 20230369425
    Abstract: a transistor and an interconnect structure disposed over the transistor. The interconnect structure includes a first dielectric layer, a first conductive feature in the first dielectric layer, a first etch stop layer (ESL) disposed over the first dielectric layer and the first conductive feature, a dielectric feature disposed in the first ESL, an electrode disposed over the dielectric feature, and a second ESL disposed on the first ESL and the electrode.
    Type: Application

  • Publication number: 20180042819
    Abstract: A systems and methods for determining a position of a medical tube within a patient is provided. In one example, systems and methods are provided for a self- detection positioning system that is capable of determining a location of a distal end of a medical tube placed within a patient, and notifying a physician of the location of the distal end of the medical tube.

  • Patent number: 8517350
    Abstract: An improved venturi apparatus for the incorporation of air into a liquid as it is poured from a bottle. The preferred embodiment of the invention comprises an entry section, a constricted intermediate section, and an outflow section. Lateral tubes extend from the constricted intermediate section so as to form an acute angle relative to both the central and cross-sectional axes of the constricted intermediate section, thereby preventing leakage of liquid out through the lateral tubes during use and subsequent handling. The device includes a ventilation tube with a ventilation cavity for capturing backwash of the liquid as pouring is terminated, and for preventing leakage from the ventilation port.
