Abstract: The present disclosure relates to control systems, clock synchronization methods, controllers, node devices, and vehicles. In one example control system provided in this application, a primary controller directly sends a reference clock signal to at least one node device by using a ring network, so that the at least one node device can perform timing based on a frequency of the reference clock signal.
Abstract: An atomization device includes a housing, an oil storage tank provided within the housing to store oil, and a breath detector provided within the housing. The housing includes a suction part for suction by a user and a mist outlet pipeline provided in the suction part. The mist outlet pipeline has a mist outlet port exposed on a surface of the suction part. An atomization channel is formed within the oil storage tank and has a mist outlet end connected with a mist inlet end of the mist outlet pipeline. A first gas passage connected with the breath detector is formed within the housing. The suction part is provided with a first gas hole connected with the first gas passage. Each of the atomization channel, the oil storage tank and the mist outlet pipeline is isolated from the first gas passage.
Abstract: A frame structure of a dual screen extender includes a support body. Two clamping portions are slidably arranged on two sides of the support body. Sliding rods are arranged on the clamping portions. Sliding channels are formed on the support body. The sliding channels are matched with the sliding rods. An elastic tensioning piece is arranged in each of the sliding channels. Each elastic tensioning piece is configured to provide elastic tensioning force for a corresponding sliding rod. At least one of the two clamping portions is provided with a screen support. The screen support is rotatable. The screen support is stacked on the support body when the screen support is rotated to be fully folded. A state maintaining assembly is arranged on each of the clamping portions. Each state maintaining assembly is configured to position the screen support before and after rotation of the screen support.
Abstract: An image capture apparatus and a zoom lens are provided. The zoom lens in accordance with an exemplary embodiment of the invention includes a mount, a guide unit, a plurality of lens groups and a driving device. The guide unit is disposed in the mount in a first direction. The lens groups are disposed in the mount and include at least one movable lens group which can be moved along the guide unit. The driving device is configured for driving the movable lens group. The driving device includes magnets and coils. The magnets are fixed to one of the movable lens group and the mount, while the coils are fixed to the other of the movable lens group and the mount. The magnets and/or the coils are arranged in the first direction.

Abstract: An electronic device is provided. The electronic device comprises a housing component and a microphone disposed in the housing component. The housing component is provided with a sound pickup channel. The microphone is configured to pick up a sound transmitted through the sound pickup channel. The sound pickup channel includes a first channel section and a second channel section communicated with each other. The first channel section is closer to the microphone than the second channel section. A first central axis of the first channel section and a second central axis of the second channel section do not coincide. The first channel section and the second channel section of the sound pickup channel are staggered from each other, which helps avoid external droplets, or the like, from directly impacting the microphone, thereby extending the service life of the microphone.
