  • Patent number: 10399071
    Abstract: A polymer containing a carboxyl group, a preparation method and an application thereof, a supported catalyst and a preparation method thereof and preparation methods of penem antibiotic intermediate are disclosed. The polymer has high rigidity and hardness, thus the mechanical properties of the polymer is effectively improved. Meanwhile, in the polymer, the carboxyl group is used as a main functional group, and is used as a carrier to prepare, by means of a coordination reaction between the carboxyl group and a heavy metal, a supported metal catalyst which has better connection stability between the metal and the polymer. The above two factors can improve the stability of the supported metal catalyst, such that the catalyst can be recycled without losing the catalytic activity. Meanwhile, loss of a heavy metal active ingredient and production cost can be reduced.

  • Patent number: 10379671
    Abstract: According to a touch event processing method and apparatus, and a terminal device, if a multi-point touch event that is not processed and that is to be discarded exists, and an application program running in a foreground is a key application program, touch points falling within a target control response area of the application program running in the foreground are determined in touch points of the multi-point touch event. Then, a new touch event is obtained according to the touch points falling within the target control response area, and the new touch event is re-transferred to the application program running in the foreground, so that the application program running in the foreground responds to the new touch event. This resolves a problem that, in some scenarios, a touchscreen does not respond to a touch operation performed by a user.

  • Publication number: 20190171737
    Abstract: 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.
