Abstract: Methods, systems, and apparatus, including computer-readable media, for authentication requests from third party interfaces. In some implementations, an information request is received to an information system from a computing system that provides a natural language interface, wherein the information request is associated with a user, and (ii) a token corresponding to the information request. In response to receiving the information request, a user data request and the token corresponding to the information request are sent for requesting user profile information for the user associated with the information request. A user identifier is extracted from user profile information received from the trusted profile provider system. A user identity is identified for the user based on a match between the extracted user identifier and a user identifier in a user registry associated with the information system. The information request is processed based on the identified user identity.

Abstract: A laser soldering device includes a laser source, a lens group, a temperature sensor, and a feedback controller. The laser source emits a laser beam, which is power-adjustable, according to a control signal. The temperature sensor receives infrared rays radiated when the laser beam is irradiated to the soldering point to detect the temperature of the soldering point, and correspondingly outputs a sensing signal according to the detected temperature. When the detected temperature falls into a first temperature range based on a target temperature, the feedback controller executes a PID algorithm to calculate a predicted error value according to an error value between the detected temperature and the target temperature. The feedback controller controls the laser source according to the predicted error value, and adjusts the power of the laser beam accordingly, so that the detected temperature can be substantially equal to the target temperature.
