Patent number: 9687866Abstract: A liquid soap dispenser includes a cap adapted to be mounted onto a container. A cylinder longitudinally and rotatably extends through the cap. A tube is longitudinally connected to a lower end of the cylinder. A discharge tube is partially longitudinally received in the cylinder. The discharge tube has a lower end received in the cylinder and abutting against an inner periphery of the cylinder and is reciprocally moved relative to the cylinder. A push-button is mounted onto a top of the discharge tube. A negative pressure relative to the space in the container is intermittently formed in the cylinder such that the liquid soap in the container will sequentially pass through the tube, the discharge tube and the push-button when the push-button is reciprocally pressed and the piston of the discharge tube is reciprocally moved relative to the cylinder.Type: GrantFiled: February 19, 2016Date of Patent: June 27, 2017Assignee: LIVING FOUNTAIN PLASTIC INDUSTRIAL CO., LTD.Inventor: Ching-Chung Chan

Patent number: 8423481Abstract: A self-learning method for keyword based human machine interaction is disclosed. At least one of a plurality of keywords predetermined in a database is selected and a priority score of the selected keyword is updated and a weighted factor is generated for the selected keyword. A weighted score and the weighted factor of the selected keyword are transmitted to the keywords related to the selected keyword. The selected keyword is pushed to a keyword buffer and linkage strengths between the keywords in the keyword buffer are strengthened. When a keyword has been stored in the keyword buffer for over a predetermined reset time period, a reset operation is performed to remove the keyword from the keyword buffer.Type: GrantFiled: October 6, 2009Date of Patent: April 16, 2013Assignee: Mitac International Corp.Inventors: Yin-pin Yang, Ching-Chung Chan, Xiao-Ming Lin
