Patent number: 11429581Abstract: A method and/or system for managing a database that stores space-time context objects is provided. The system receives a query range in a multi-dimensional space. The system maps the query range into a set of fragments of a space-filling curve that fills the multi-dimensional space in all dimensions of the multi-dimensional space. The system uses each mapped fragment in the set of mapped fragments as a key to query the database for space-time context objects that are mapped to the space-filling curve. The system queries the database by identifying one or more context objects that intersect the mapped fragment at the space-filling curve.Type: GrantFiled: December 1, 2017Date of Patent: August 30, 2022Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Ning Duan, Chun Yang Ma, Makoto Tanibayashi, Zhi Hu Wang, Shoichiro Watanabe, Nan Xia, Xin Zhang, Jun Zhu

Patent number: 11249328Abstract: A one-way glass based on the persistence of vision of human eyes includes a double glazing or a single glazing. The double glazing includes a switchable glass with electrically controllable and adjustable light transmittance, and a luminous glass that is electronically controlled to emit light. The luminous glass is a transparent glass. The switchable glass and the luminous glass are controlled by pulse signals of a pulse controller. When the luminous glass emits light, the switchable glass does not transmit light. When the switchable glass transmits light, the luminous glass does not emit light. Dot-matrix LED light sources are uniformly provided on the single glazing. A side of the dot-matrix LED light source facing indoors is provided with a light-shielding layer. A transparent gap is formed between adjacent dot-matrix LED light sources.Type: GrantFiled: December 16, 2019Date of Patent: February 15, 2022Assignee: HANGZHOU QISU TECHNOLOGY CO., LTD.Inventor: Nan Xia
