Patent number: 10099191Abstract: 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.Type: GrantFiled: June 22, 2017Date of Patent: October 16, 2018Assignee: TRIPOD TECHNOLOGY CORPORATIONInventors: Lin Lu, Kuei-Sheng Fan, Chen-Hsiang Wang, Chun-Lun Chiu, Ta-Wei Chang, Cheng-Ding Wang, Jim-Min Fang

Patent number: 9875191Abstract: 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.Type: GrantFiled: November 13, 2015Date of Patent: January 23, 2018Assignee: NATIONAL CHENG KUNG UNIVERSITYInventors: Ta-Wei Chang, Ing-Chao Lin, Wen-Yu Su, Yu-Shiang Chien

Patent number: 9372802Abstract: 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.Type: GrantFiled: June 4, 2014Date of Patent: June 21, 2016Assignee: Acer IncorporatedInventors: Po-Wei Wu, Ta-Wei Chang, Hsung-Pin Chang

Patent number: 9146876Abstract: 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.Type: GrantFiled: April 16, 2013Date of Patent: September 29, 2015Assignee: Acer IncorporatedInventors: Po-Wei Wu, Hsin-Yu Chen, Hsung-Pin Chang, Ta-Wei Chang
