Abstract: A method and a wearable apparatus for disease diagnosis are provided. The method is applied to the wearable apparatus with an image capturing unit and a display unit. In this method, a plurality of input images in a field of view of the wearable apparatus are captured by using the image capturing unit, wherein each of the input images contains an array of pixels. The variations of the pixel values in a time domain are analyzed. The pixel variations within a specific frequency range are magnified and the magnified pixel variations are added onto the original ones to generate an output image. The output image is overlapped with a current image in the field of view of the wearable apparatus and displayed on the display unit.

Abstract: A bioabsorbable polymeric stent with time dependent structure and properties and methods of treating a diseased blood vessel with the bioabsorable polymeric stent are disclosed. The structure and properties of the stent change with time and allow the vessel to be restored to a natural unstented state. The bioabsorbable stent loses mechanical integrity in a controlled manner due to modification of selected structural elements.

Abstract: A drug eluting depot stent is provided. The stent has two free ends and a tubular body connected therebetween. The tubular body includes a series of rings having undulating structures. Each of the undulating structure has a bar arm and a crown connected thereto. The bar arm has a first end portion, a second end portion and a mid-section defined therebetween. The bar arm has opened regions defined at the first end portion, the mid-section, and the second end portion, respectively. The opening ratio of the mid-section is larger than that of the two end portions. With the aforementioned structure, the stress concentration at the crown region can be re-distributed towards the bar arm, and thus effectively prolonging the fatigue life of the stent.

Abstract: An expandable stent is implanted in a body lumen, such as a coronary artery, peripheral artery, or other body lumen. The stent includes a plurality of rings connected by links. The stent has a high degree of flexibility in the longitudinal direction, yet has adequate vessel wall coverage and radial strength sufficient to hold open an artery or other body lumen. The stent can be compressed or crimped onto a catheter to a very low profile since links are integrally formed from a portion of the struts forming the rings. The stent is constructed so that the cylindrical rings are very close together in order to provide maximum scaffolding, and if the stent has a drug coating, to provide a uniform drug delivery over the length of the stent. The connecting links are integrally formed from a portion of the struts forming the rings so that the links can have a maximum length thereby providing increased longitudinal flexibility of the stent.

Abstract: A non-destructive composite material inspection apparatus and method thereof inspect the fiber direction and fracture toughness. The apparatus includes a light module and a stereoscopic microcamera module. The light module generates a polarized light that has a polarization orientation projecting to an inspection area on the surface layer of the composite material. The stereoscopic microcamera module captures the reflection light from the inspection area and outputs an image. When the polarization orientation and the fiber direction are parallel, the image is a bright field image. When the polarization orientation and the fiber direction are orthogonal, the image is a dark field image. The bright and dark field images show the fiber direction and toughened particle distribution and the toughness of the composite material is then predicted.

The number of first interconnection members is different than the number of second interconnection members.
