  • Patent number: 10294838
    Abstract: An exhaust cleaning filter has an exhaust gas inflow passage and an exhaust gas outflow passage disposed in alternating fashion; and a porous partition wall for setting the exhaust gas inflow and outflow passages at a distance from each other. A small pore region is sectioned off on the upstream side and a large pore region is sectioned off on the downstream side of the partition wall. The average pore diameter of the partition wall in the large pore region is greater than in the small pore region, and is set so that ash contained in the exhaust gas is able to pass through the partition wall. The exhaust purification filter has a promoting member for promoting the passing of exhaust gas that has flowed into the exhaust gas inflow passage, through the partition wall in the small pore region, and promoting inflow into the exhaust gas outflow passage.

  • Patent number: 10108361
    Abstract: The embodiments provide facilitate storage of content from a terminal device in a cloud environment. Storage servers, a front server, and terminal devices are connected to a network. Each terminal device carries out an operation to the front server to store created content. The front server acquires the account of each of the storage servers in advance. The front server splits received content into split files, and stores the split files on different storage servers, respectively. The terminal device requests the front server to download the stored content. The front server acquires the split files from the storage servers, restores the content, and sends the restored content back to the terminal device. The front server encrypts and stores, with a public key of the terminal device, meta information for decrypting the content from the split files.

  • Publication number: 20180046319
    Abstract: Disclosed is a method for determining an intentional touching event on a touchscreen, including a touchscreen virtual keyboard, by individualizing and/or adjusting a touch signal threshold value to obtain a calibrated value, wherein the touch signal threshold value is used in determining an intentional touching event by determining if a strength of a touch signal associated with a touching event falls above or below the calibrated threshold value. Adjusting the touch signal threshold value may be based on the user's active input, and may be statistically determined based on at least one sample of touch signal values.
