  • Publication number: 20240135102
    Abstract: A method of this disclosure may include performing a named entity recognition on text information related to requirements for a wireframe by a first artificial intelligence (AI) model, so as to extract entities and relations of the entities from the text information. The method may further comprise inputting the extracted entities and relations to a second AI model to generate the wireframe, wherein the second AI model is trained so that a difference between resultant relations of the entities of the generated wireframe and the extracted relations of the entities from the first AI model is decreased.

  • Patent number: 11880533
    Abstract: A power management circuit can comprise a direct-current-to-direct-current (DC-DC) converter and a guard buffer. The guard buffer can be referenced to a system ground and configured to generate a guard ground. The power management circuit can comprise a supply capacitor coupled to the DC-DC converter that can be referenced to system ground in a first mode and referenced to the guard ground in a second mode. A regulator can be coupled to the DC-DC converter and referred to system ground in the first mode, and decoupled and referred to guard ground in the second mode. The DC-DC converter can generate a first voltage in the first mode and a second voltage in the second mode, the second voltage greater than the first.

  • Patent number: 11677838
    Abstract: The embodiments of the present application disclose an acquisition method, apparatus, device and storage medium for applet data, relating to the technical field of the IoT, which are specifically implemented by: establishing a network connection with a data server according to an interface address of the data server corresponding to the applet when a trigger operation for starting the applet is detected; sending a data request message to the data server directly through the pre-established network connection after the applet is started, and receiving, from the data server, a data response message that contains requested data. Therefore, excessive time consumption caused by failing to pre-establish network connection before the first data request is sent can be avoided, and the acquisition efficiency of applet data can be improved.

  • Patent number: 11586425
    Abstract: The technical solutions relate to the technical field of compilation of applications, and particularly to the technical field of mini programs. A developer tool constructs a first compilation result of the hosted APP before compilation optimization and a second compilation result of the hosted APP after the compilation optimization respectively based on a source code of the hosted APP, and uploads them to a management platform. The management platform sends the corresponding compilation results according to environment data of the hosted APP running environment provided by the host APP, so that the host APP uses the hosted APP running environment provided by the host APP to run the obtained compilation result.

  • Patent number: 11199933
    Abstract: Some touch screens can be formed by at least partially integrating touch sensing circuitry into a display pixel stackup. In some examples, noise can be introduced into touch sensor panel measurements, for example, from display data lines of a display device proximate to the touch sensor panel. In some examples, rows or columns of touch electrodes can be split and a first portion of the touch sensor panel can be stimulated to measure capacitance and noise and a second portion of the touch sensor panel can be unstimulated and measure noise. In some examples, both the first and the second portions of the touch sensor panel can be stimulated using orthogonal stimulation codes. In some examples, measurements from the first and/or second portions of the touch sensor panel can be subtracted from measurements from the other portion of the touch sensor panel to eliminate or reduce common mode noise.
