Abstract: A mechanism to render a lens module immune to trembling and jarring includes a carrier, a support element movably mounted on the carrier, and a driving element. The driving element includes a conductive structure arranged on the carrier, a plurality of positive pads on the carrier, and a plurality of shape memory alloy (SMA) wires. The SMA wires are electrically connected to the positive pads and the conductive structure. When currents flow into the SMA wires via the positive pads, the SMA wires deform upon heating and pull on the conductive structure, thus the conductive structure drives the support element to rotate in a plane parallel to the carrier. A lens module and an electronic device including the mechanism are also disclosed.

Abstract: A microphone module, including a substrate assembly, two sensing structures, and two housings, is provided. The substrate assembly has at least one through hole and at least one circuit structure electrically connected to at least one pad. The through hole includes two holes formed on opposite sides of the substrate assembly. The sensing structures are disposed on and cover the two holes. The two sensing structures and the through hole collectively form a communicating cavity. A size of the communicating cavity in an axial direction is greater than that in a radial direction. The two housings are respectively disposed on the opposite sides of the substrate assembly and respectively shield the two sensing structures. Each of the housings, the substrate assembly, and the corresponding sensing structure form an inner cavity. The housings each has a sound hole. The inner cavity communicates with the outside through the sound hole.

Abstract: The present disclosure provides a microphone apparatus. The microphone apparatus may include a microphone and a vibration sensor. The microphone may be configured to receive a first signal including a voice signal and a first vibration signal. The vibration sensor may be configured to receive a second vibration signal. And the microphone and the vibration sensor are configured such that the first vibration signal may be offset with the second vibration signal.

Abstract: Provided is a support arm, including a guide assembly configured to be connected to a gantry of a radiotherapy equipment; a support bracket movably connected to the guide assembly and configured to support a detector; and a drive assembly connected to the support bracket and configured to drive the support bracket to move on the guide assembly.

Abstract: A balancing vehicle includes a wheel, a bracket, a frame, a shock absorbing member, pedals, a control rod, and a handle. The bracket is fixed to an axle of the wheel. The frame is slidably connected to the bracket through a slider fixedly connected to the bracket, so as to allow the frame to slide relative to the bracket. The shock absorbing member is disposed between the frame and the bracket, and is configured to cushion relative movement between the frame and the bracket. The pedals are fixed to the frame. The control rod is configured to move back and forth in a direction of travel. The balancing vehicle accelerates when the control rod is pushed forward in the traveling direction, and the balancing vehicle decelerates or retreats when the control rod is pulled backward in the traveling direction. The handle is coupled to a top of the control rod.

Abstract: The present disclosure discloses a method and a system for generating a composite PET-CT image based on a non-attenuation-corrected PET image. The method includes: constructing a first generative adversarial network and a second generative adversarial network; obtaining a mapping relationship between a non-attenuation-corrected PET image and an attenuation-corrected PET image by training the first generative adversarial network; obtaining a mapping relationship between the attenuation-corrected PET image and a CT image by training the second generative adversarial network; and generating the composite PET-CT image by utilizing the obtained mapping relationships. According to the present disclosure, a high-quality PET-CT image can be directly composited from a non-attenuation-corrected PET image, and medical costs can be reduced for patients, and radiation doses applied to the patients in examination processes can be minimized.
