Abstract: Disclosed are a crane and a control method therefor. The crane comprises a body, a boom, a luffing mechanism, a tension sensor, and a controller. One end of the boom is rotatably connected with the body. The luffing mechanism is respectively connected to the body and the boom. The tension sensor is disposed on the luffing mechanism, and the tension sensor is used for detecting a tension value of the luffing mechanism to the boom. The controller is electrically connected to the tension sensor and the luffing mechanism, and the controller is configured to determine that the arm length of the boom exceeds an arm length threshold if the tension value is greater than a tension threshold.

Abstract: A chassis of a movable platform is provided, including a chassis body and a wheel assembly, the chassis body is configured to support an actuator of the movable platform, the wheel assembly is movably connected to the chassis body to switch between a first state and a second state, in the first state, all or part of the wheel assembly is located in an outer area of a side surface of the chassis body, and in the second state, the wheel assembly is positioned to avoid the actuator, so as to allow the actuator to move to the outer area of the side surface of the chassis body to perform a corresponding operation. A movable platform including the chassis is also provided to enhance the operational flexibility of the movable platform and improve the overall operational stability of the platform.

Abstract: Techniques are described herein for using a smart device such as a standalone assistant-centric interactive speaker and/or a standalone assistant-centric interactive display with speaker(s) to send a message using a messaging application on a client device such as a smartphone. A method includes: receiving, by a first device, a request from a first user to send a message to a second user; determining that a messaging application corresponding to the request is unavailable on the first device; and in response to determining that the messaging application corresponding to the request is unavailable on the first device: selecting a second device on which the messaging application corresponding to the request is available; and sending, to the second device, a command that causes the second device to send the message from the first user to the second user using the messaging application on the second device.

Abstract: A mounting mechanism includes a base plate, a support arm, and a fixing frame. The support arm is mounted at the base plate. The fixing frame includes a connection end and a mounting end opposite to each other. The connection end is mounted at the support arm and configured to rotate relative to the support arm. The mounting end is configured to be selectively engaged with or separated from the base plate. The support arm is configured to be fixed relative to the base plate to clamp at a track when the mounting end is engaged with the base plate, and rotate relative to the base plate when the mounting end is separated from the base plate.

Abstract: The present disclosure provides a base robot. The robot includes a base; a multi-piece housing movably mounted on the base covering a part of the base when the housing is closed, and exposing the base when the housing is opened; and a driving assembly connecting the base and the housing, and driving the housing to move relative to the base, and opening or closing the housing.

Abstract: A device for processing and storing data is disclosed, which comprises a primary controller, a primary memory, a security element (SE), and at least one universal port, wherein the device for processing and storing data further includes a first additional port, via which the security element (SE) can directly interacts with a second external device to complete the processing and access of the data. The security element (SE) in the device for processing and storing data disclosed herein can work independently without being effected by the condition whether the primary memory is performing the data read/write process, and supports the single wire protocol (SWP).
