Abstract: In an embodiment, a system includes base stations and a server. Each base station has a respective fixed position, and is configured to broadcast information that a mobile station can use to determine a position of the mobile station. And the server is configured to communicate with the base stations and to track a position of a mobile station. An example of such a system is an Aeronautical Mobile Airport Communications System (AeroMACS), which includes base stations that are located in respective fixed, known positions within and around an airport, and at least one server that communicates with the base stations and tracks the positions of moveable stations within and around the airport. The base stations can provide information that allows both GNSS-enabled and non-GNSS-enabled mobile stations to determine their positions without adding significant cost or complexity to the AeroMACS.

Abstract: Drug eluting stents, methods of making, using, and verifying long-term stability of the drug eluting stents, and methods for predicting long term stent efficacy and patient safety after implantation of a drug eluting stent are disclosured. In one embodiment, a drug eluting stent may include a stent framework; a drug-containing layer; a drug embedded in the drug-containing layer; and a biocompatible base layer disposed over the stent framework and supporting the drug-containing layer. The drug-containing layer may have an uneven coating thickness. In addition or in alternative, the drug-containing layer may be configured to significantly dissolve/dissipate/disappear between 45 days and 60 days after stent implantation. Stents may reduce, minimize, or eliminate patient risks associated with the implantation of a stent, including, for example, restenosis, thrombosis, and/or MACE.

Abstract: An optical system for assisting image positioning. The system comprises a light source (1), and further comprises a dot pattern or an interface beam-splitting pattern which is arranged on a light-emergent light path of the light source (1) and generates an interface beam-splitting projection light ray for indicating a text or an image after being projected by emergent light of the light source (1). By means of a combination of a light source (1) and a dot pattern or an interface beam-splitting pattern, a word line, a cross line, or the other patterns which can generate a beam-splitting interface can be projected. Furthermore, by virtue of a DOE moulding lens, of which an emergent face is a spherical face or an aspherical face, a specific linear light beam or the other patterns which can generate the beam-splitting interface are generated. Rapid positioning and capturing of a specific part of an image or a specific image are realized, and the accuracy is high.
