Abstract: A method executable by an autonomous mobile device includes moving in a work environment, obtaining environmental data acquired by a sensing device, and determining whether the sensing device is in a suspected ineffective state based on the environmental data. The method also includes based on a determination that the sensing device is in the suspected ineffective state, rotating at a same location for a first predetermined spin angle. The method also includes obtaining an estimated rotation angle based on one or more motion parameters acquired by a dead reckoning sensor, comparing the estimated rotation angle with the first predetermined spin angle, and based on a determination that a difference between the estimated rotation angle and the first predetermined spin angle is greater than a first predetermined threshold value, executing escape instructions to move backwardly for a first predetermined distance and move along a curve or a folded line.

Abstract: A surgical robot system includes a platform and at least one positioning arm. The at least one positioning arm each includes a first cross arm and a first rotary joint, the first rotary joint is arranged in the first cross arm or the platform, a proximal end of the first cross arm is rotatably connected to the platform via the first rotary joint, and the first cross arm is operable to rotate about a longitudinal axis relative to the platform. By overlapping first cross arms of a pair of positioning arms and coaxially connecting the first cross arms to the platform, the longitudinal space occupation of the positioning arms can be reduced, and the risk of interference and collision between the positioning arms is reduced.

Abstract: An integrated circuit is provided, which includes: a processor, a general interrupt controller, and a bus master. The bus master includes: a bus-control circuit and a polling circuit, which is configured to detect whether an interrupt signal of the sensing device is asserted. In response to the polling circuit detecting that the interrupt signal is asserted, the bus-control circuits fetches each task stored in a task queue of a memory in sequence, and performs one or more data-transfer operations corresponding to each task to obtain sensor data from the sensing device. In response to a task-completion signal of the tasks generated by the bus-control circuit, the general interrupt controller generates an interrupt request signal. In response to the interrupt request signal, the processor reports a sensor event using the sensor data obtained by the data-transfer operations corresponding to each task.

Abstract: A large aperture anamorphic lens includes a cylindrical lens group arranged in a direction from an object side to an image side. The cylindrical lens group includes a anamorphic group and together form an imaging group. The anamorphic group includes a first lens, a second lens, and a third lens arranged in a direction of an object side to an image side. The first lens and the second lens may be a negative optical power cylindrical lens, and the third lens may be a positive optical power cylindrical lens. Through the optical characteristics of the cylindrical lens in the anamorphic group, the entering horizontal light is compressed while the vertical light path maintains unchanged. The imaging group comprehensively corrects the light so that the horizontal field of view angle is increased by about 33% to achieve a magnification by 1.33 times for an anamorphic shooting.

Abstract: The present disclosure discloses a display method of a display panel, a display device and a display apparatus. A received high resolution (first resolution) image data is decomposed into multiple frames (n frames) of low resolution (second solution) image data, and for multiple frames (n frames) of low resolution image data corresponding to each frame of high resolution image data, various frames of image data in the multiple frames of second resolution image data are refreshed frame by frame at a predetermined frame refresh frequency. In this way, multiple frames of low resolution images which are presented in turn are observed by human eyes, and are combined into an original high resolution image by a brain, so as to achieve an effect of viewing an image with a high resolution. The present disclosure achieves the effect of viewing an image with a high resolution by increasing a refresh frequency of the low resolution image data.
