    • The invention relates to methods and apparatus for monitoring movement and breathing of two or more subjects occupying common bedding. Particularly, the invention relates to a method for monitoring movement of subjects located in a common bedding, the method comprising the steps of: —imaging the bedding by an optical sensor; —performing a motion estimation by producing motion vectors indicating the local displacement of corresponding image blocks between consecutive images, or images that are several frames apart, received from said optical sensor; —calculating motion clusters by measuring spatial and temporal correlations of the motion vectors; —segmenting the calculated motion clusters by assignment of each motion cluster to a corresponding subject, wherein the assignment of the motion clusters to the corresponding subject is based on the spatial and/or temporal similarity of the motion clusters among each other and on previous segmentation results.
    • 本发明涉及用于监测占用普通床上用品的两个或多个受试者的运动和呼吸的方法和装置。 特别地,本发明涉及一种用于监测位于普通床上的物体的运动的方法,所述方法包括以下步骤: - 通过光学传感器成像床上用品; - 通过产生指示在所述光学传感器中接收的连续图像之间的相应图像块的局部位移或相隔几帧的图像的运动矢量来执行运动估计; 通过测量运动矢量的空间和时间相关性来计算运动群; - 通过将每个运动簇分配给对应的对象来分割所计算的运动群集,其中运动群集对相应对象的分配基于彼此之间的运动群集的空间和/或时间相似性以及先前的分割结果 。

    • A light therapy device (1) comprises: at least one light source (2); a control device (10) for controlling the operation of the light source; a boundary memory (11) containing boundary information defining boundaries for the distance (D) and relative angle (f) of a user's head with respect to the light source; monitoring means (30) for monitoring the actual distance and actual relative angle of the user's head and generating an output signal indicating the measured distance and angle. The control device has an input coupled to the memory for receiving the boundary information, and has an input coupled to the monitoring means for receiving the output signal from the monitoring means. The control device compares the output signal from the monitoring means with the boundary information, and issues a warning signal when the actual position and/or orientation of the user's head and/or eyes is/are outside said boundaries.
    • 光疗装置(1)包括:至少一个光源(2); 用于控制光源的操作的控制装置(10); 边界存储器(11),其包含限定用户头部相对于光源的距离(D)和相对角度(f)的边界的边界信息; 监视装置(30),用于监视用户头部的实际距离和实际相对角度,并产生指示测量的距离和角度的输出信号。 控制装置具有耦合到存储器的用于接收边界信息的输入,并且具有耦合到监视装置的输入端,用于从监视装置接收输出信号。 控制装置将来自监视装置的输出信号与边界信息进行比较,并且当用户的头部和/或眼睛的实际位置和/或取向在/超出所述边界时发出警告信号。
