Abstract: Training a predict model with network traffic and data change messages generated by an existing web application running in a production environment. The predict model being is trained to predict data changes resulted from API calls embodied in network traffic. A stream of network traffic of the existing web application is replayed with an upgraded version of the existing web application to generate real data changes. The stream of network traffic is applied to the predict model to generate predicted data change messages. The predicted data change messages are comparing with real data change messages representing the real data changes. One or more existing APIs is identified as being possibly functionally degraded based on any inconsistency of the predicted data change messages with the real data change messages.

Abstract: A touch sensor includes a substrate, sensing channels, and a protective layer. The sensing channels are disposed at intervals on a surface of the substrate, and any one of the sensing channels includes an electrode portion and a silver trace portion electrically connected to the electrode portion. The protective layer is disposed on the substrate and covers and encapsulates the sensing channels. After the touch sensor is subjected to a salt spray test with sodium chloride solution of a mass percentage concentration of 5% at a rate of 1 mL/H to 2 mL/H under an ambient temperature of 35° C. for 48 hours, a resistance change rate of any one of the sensing channels is less than or equal to 10%, and a resistance distribution difference between the sensing channels is less than or equal to 10%.

Abstract: An electronic billboard includes a base, bracket, a display and a touch device. The bracket is removable and mounted to the base. The display is removable and mounted to the bracket. The display includes a slot and a receiving portion configured to receive a host. The touch device is received in the slot.

Abstract: A supporting device is used to support a display. The supporting device includes two fixing parts, two supporting arms, and a base. The base can be made by bending a rod in a plane. The fixing parts are fixed with the display. Each supporting arm includes a connecting portion and an assembly portion. The connecting portion connects an end of the fixing part. The assembly portion is fixed with the base. An extending direction of the supporting arm is substantially perpendicular to the plane with the rod.

Abstract: An electronic device with supporting structure includes a connection member, a back shell, two first fixing portions, and two second fixing portions. The connection member is attached to the supporting structure and defines two connection holes. Each connection hole includes a first through hole and a second through hole. A diameter of the second through hole is greater than that of the first through hole. The two first fixing portions are protruding from the back shell and are slidable between the second through holes and the first through holes. The two second fixing portions are attached to the two first fixing portions and can pass through the two second through holes. The connection member can prevent the two second fixing portions passing through the first through holes when the first fixing portions slide to the first through holes.
