  • Patent number: 10742902
    Abstract: A tracking system is provided. The tracking system comprises a trackable device which comprises a first illuminating module and the first illuminating module emits an infrared (IR) light and a tracking device which comprises an optical sensing module and a processor. The optical module is configured to sense an IR spectrum to capture a first image and sense a visible spectrum to capture a second image, and the IR light is in the IR spectrum. The processor is coupled to the optical sensing module. The processor is configured to search in the first image a first region corresponding to the IR light, locate in the second image a second region associated with the first region in the first image, and calculate a spatial status of the trackable device according to the second region in the second image.

  • Publication number: 20200201782
    Abstract: A memory page management method is provided. The method includes receiving a state-change notification corresponding to a state-change page, and grouping the state-change page from a list to which the state-change page belongs into a keep list or an adaptive LRU list of an adaptive adjusting list according to the state-change notification; receiving an access command from a CPU to perform an access operation to target page data corresponding to a target page; determining that a cache hit state is a hit state or a miss state according to a target NVM page address corresponding to the target page, and grouping the target page into the adaptive LRU list according to the cache hit state; and searching the adaptive page list according to the target NVM page address to obtain a target DRAM page address to complete the access command corresponding to the target page data.

  • Patent number: 10438843
    Abstract: A structure of semiconductor device includes a substrate. A first dielectric layer is disposed over the substrate, wherein the first dielectric layer has an air trench. A plurality of trench metal layers is disposed in the first dielectric layer, wherein the air trench is between adjacent two of the trench metal layers and without contacting to the trench metal layers. A liner layer is disposed on the first dielectric layer to cover the trench metal layers and a profile of the air trench. An etching stop layer is disposed on the liner layer, wherein the etching stop layer seals the air trench to form an air gap between the adjacent two of the trench metal layers.
