The invention relates to the field of the Internet of Things, and in particular, to an OTA differential upgrade method and system of a master-slave architecture. The method comprises: Step S1, obtaining an upgrade scheme, and determining a master-slave connection relationship and an upgrade manner according to the upgrade scheme; Step S2, downloading a differential upgrading file; Step S3, determining a processing mode of a master node according to the upgrading manner of a slave node; if the upgrading manner of the slave node is a first manner, the node flashes and restores the differential upgrading file and sends the differential upgrading file to the slave node, so that the slave node completes upgrading; if the upgrading manner of the slave node is a second manner, the master node flashes and restores the differential upgrading file and sends the differential upgrading file to the slave node for upgrading.

OTA differential upgrade method and system of master-slave architecture

According to one embodiment, a method, computer system, and computer program product for webpage replay is provided. The embodiment may include acquiring one or more commands each indicating changes of at least one virtual Document Object Model (DOM) node of a virtual DOM of a webpage corresponding to a timestamp for a session. The embodiment may include determining one or more virtual DOM differentials corresponding to respective timestamps for the session based on the one or more commands and a first data dictionary. The first data dictionary is created based on a base virtual DOM of the webpage including a plurality of virtual DOM nodes. The embodiment may include generating one or more patched virtual DOMs of the webpage corresponding to respective timestamps for the session. The embodiment may include replaying the webpage for the session based on the base virtual DOM and the patched virtual DOMs.

Replaying a webpage based on virtual document object model

A method includes receiving, by a device, a request to input information through a virtual canvas, the device includes a projector and a camera, the virtual canvas providing an input space to a user of the device, the virtual canvas includes a region of a blank surface illuminated by the projector, based on the received request, enabling the projector and the camera, detecting a distance between the device and the virtual canvas, based on the detected distance, adjusting the projector and the camera to focus on the virtual canvas, capturing a movement made by an object on the virtual canvas, the movement is associated with the information being input, converting the movement into a plurality of frames, each frame is associated with the movement, processing the plurality of frames to obtain the input information, and projecting the input information on the virtual canvas.

Inputting information using a virtual canvas

A computer-implemented method includes receiving, by one or more sensors, data for one or more cycles, each of the one or more cycles including one or more slots. The computer-implemented method further includes combining the one or more slots from each of the one or more cycles into a combined slot group. The computer-implemented method further includes converting the combined slot group into a converted slot group. The computer-implemented method further includes monitoring the converted slot group for an anomaly. The computer-implemented method further includes, responsive to the anomaly: Comparing the anomaly to one or more known anomalies to determine a correlation between the anomaly and the one or more known anomalies, and determining the anomaly location. The computer-implemented method further includes reporting a problem condition based on at least one of the correlation and the anomaly location. A corresponding computer system and computer program product are also disclosed.
