Abstract: A Serial Peripheral Interface (SPI) master (110) and method therein for transferring data to a peripheral device in a data communication and processing system (100) are disclosed. The SPI master (110) comprises a memory (111) comprising a list of packets, each packet comprises data associated with a time parameter indicating at which time the data is to be transferred to the peripheral device. The time parameter is configurable. The SPI master further comprises a serial transmit and receive unit (112) to transfer the data in the list at a time according to the time parameter associated with the data.

Abstract: A method for producing an interference reduced radar image comprises receiving a measured sequence of beat signals; identifying one or more interference segments within the measured sequence of beat signals, an interference segment being a segment subject to an interference; doctoring the measured sequence of beat signals by creating a doctored representation of the measured sequence of beat signals in the form of a matrix Y; creating a doctoring mask representing the doctoring of the measured sequence of beat signals, the doctoring mask being a matrix M; and estimating a reconstructed range-doppler image {circumflex over (X)} from Y and M, wherein the reconstructed range-doppler image is a range-doppler image of Y which is deconvolved using M; such that doctoring the measured sequence of beat signals at least partially removes interference effects and estimating a reconstructed range-doppler image at least partially removes image artefacts created by the doctoring.

Abstract: The present application relates to methods and systems for including sensor data from a sensor unit (108) as an overlay (204) in a video stream from a camera (106) monitoring a scene (200). The overlay has overlay regions (206a-f) corresponding to scene regions (202a-f), and when the sensor unit detects motion in a scene region a graphical element (208) is added to the overlay in the overlay region corresponding to that scene region. Video analytics procedures, such as object feature detection or motion or change detection may then be used to determine if detection has been made in a specific scene region by both the camera and the sensor unit.
Abstract translation: 本申请涉及用于将来自传感器单元（108）的传感器数据作为监视场景（200）的相机（106）的视频流中的覆盖（204）的方法和系统。 覆盖层具有对应于场景区域（202a-f）的覆盖区域（206a-f），并且当传感器单元检测到场景区域中的运动时，图形元素（208）被添加到对应于该场景的覆盖区域中的覆盖层 地区。 然后可以使用诸如对象特征检测或运动或变化检测的视频分析程序来确定在相机和传感器单元两者中是否在特定场景区域中进行检测。
