  • Patent number: 10099191
    Abstract: Provided is a method of making colloidal metal nanoparticles. The method includes the steps of: mixing a metal aqueous solution and a reducing agent to form a mixture solution in a reaction tank; heating the mixture solution and undergoing a reduction reaction to produce a composition containing metal nanoparticles, residues and gas, wherein the amount of the residues is less than 20% by volume of the mixture solution, and guiding the gas out of the reaction tank; dispersing the metal nanoparticles with a medium to obtain colloidal metal nanoparticles. By separating the reduction reaction step and the dispersion step, the method of making colloidal metal nanoparticles is simple, safe, time-effective, cost-effective, and has the advantage of high yield.

  • Patent number: 9875191
    Abstract: An electronic device having a scratchpad memory and a management method are provided. A recording circuit records multiple counter values which correspond to entries in a Translation Lookaside Buffer (TLB). A virtual address is matched with a first entry. If a cache miss occurs, the recording circuit updates a first counter value corresponding to the first entry, and determines if the first counter value meets a threshold criterion. If the first counter value meets the threshold criterion, the recording circuit transmits an interrupts signal to a processing unit, and the processing unit moves data into the scratchpad memory. If the first counter value does not meet the threshold criterion, the data is moved into a cache.

  • Patent number: 9372802
    Abstract: A data writing method, a hard disc module, and a data writing system for writing data into the hard disc module are provided, wherein the hard disc module includes a plurality of memory units. The data writing method includes the following steps. A cache data is received and a data class of the cache data is determined. If the data class of the cache data belongs to a first type, the cache data is distributed and written to the memory units. If the data class of the cache data belongs to a second type, the cache data is written to one of the memory units.

  • Patent number: 9146876
    Abstract: A caching method and a caching system using dual disks, adapted to an electronic apparatus having a first storage unit and a second storage unit, are provided, in which an access speed of the second storage unit is higher than that of the first storage unit. In the method, a data access to the first storage unit is monitored, a data category of the data in an access address of the data access is identified and whether the data category belongs to a cache category is determined. If the data category belongs to the cache category, an access count of the data in the access address being accessed is accumulated and whether the accumulated access count is over a threshold is determined. If the access count is over the threshold, the data in the access address is cached to the second storage unit.

  • Publication number: 20120189819
    Abstract: An odorless composite floor tile suitable for indoor or outdoor use is formed from elastomer particles. The composite floor tile has a lower layer that is formed by binding a first group of elastomer particles with an adhesive, and is stabilized with meshes of fiberglass fibers. The composite floor tile also has a laminated upper layer. The laminated upper layer is formed by binding a second group of elastomer particles with the adhesive, or formed from synthetic rubber and/or natural rubber, polymeric materials, or fiber materials. The composite floor tile has shock absorption and anti-slippage properties. The composite floor tile has an attractive upper surface that includes a variety of color patterns. Further, the composite floor tile also has a shock absorbing lower layer providing an air cushion effect that is also permeable to air and liquids which reduces or eliminates the breeding and spread of bacteria and mildew.
