摘要： A magnetic differential pressure valve is provided, having an indicator showing when the valve has moved into one of the open and closed positions, comprising a housing including a valve seat; valve means reciprocably mounted in the housing for movement towards and away from the valve seat between open and closed positions; first magnetic means movable with the valve means toward and away from the valve seat; first bias means urging the valve means and first magnetic means in one direction and normally retaining the valve means and first magnetic means in one of the closed and open positions; second magnetic means movable toward and away from the first magnetic means and normally retained in a first nonindicating position, reacting with the first magnetic means whenever the two means are within their mutually reactive magnetic fields of force, and the valve means is in one of the closed and open positions; and second bias means urging the second magnetic means into one of the nonindicating and indicating positions when the first magnetic means has moved to a predetermined distance from the second magnetic means, the second magnetic means in its indicating position indicating that the valve means has either opened or closed fluid flow communication between the first and second fluid duct means.

摘要： The present invention relates to a method and apparatus for determining visually noticeable differences between two input images. A first contrast image is generated from the first input image and a second contrast image is generated from the second input image. A contrast difference image is then formed from the two contrast images. A mean absolute difference is calculated between blocks of pixels of the first and second input image. Pixels in the contrast difference image which exceed a first threshold produce a first threshold signal and if the mean absolute difference exceeds a second threshold so a second threshold signal is produced. A detection signal is produced from the threshold signals.
摘要翻译：本发明涉及用于确定两个输入图像之间视觉上可见的差异的方法和装置。从第一输入图像生成第一对比图像，并且从第二输入图像生成第二对比图像。然后从两个对比度图像形成对比度差异图像。在第一和第二输入图像的像素块之间计算出平均绝对差。超过第一阈值的对比度差分图像中的像素产生第一阈值信号，如果平均绝对差超过第二阈值，则产生第二阈值信号。从阈值信号产生检测信号。

摘要： A video on demand system has a video server (200) for outputting video streams requested by users, via a core network (620) and access networks (630, 640, 650). A resource manager (600) determines occupation information concerning how much of the previously allocated capacity is occupied by previously authorized video streams is determined before authorizing transmitting a new requested video stream. By checking there is sufficient core network capacity, a risk of disrupting existing video streams or causing other problems by overloading the allocated capacity, is reduced or avoided. Thus less capacity in the core network is needed, and so costs of such capacity can be reduced and there is increased confidence that demand peaks will be handled more gracefully. By checking without obtaining occupation information from the core network, the system can be more independent of the core network, to reduce costs of a real time interface to the core network.

摘要： There is provided a method of removing or replacing advert slots in linear broadcast television programming when replayed as a time-shifted television asset, comprising capturing an input linear broadcast video stream to form a time-shifted television asset, detecting advert cue signals indicative of advert slot timings within the time-shifted television asset, generating metadata indicative of the advert slot timings from the detected advert cue signals, and packaging the time-shifted television asset together with the metadata, for use by a downstream system to replace or remove adverts from the time-shifted television asset. There is also provided a time-shifted television asset capture device, comprising a linear broadcast video stream input, an advert cue signal detector to detect advert cue signals, a metadata generator adapted to generate metadata from the detected advert cue signals, and a metadata and time-shifted television asset packager adapted to package the metadata and time-shifted television asset together for delivery to a downstream system.
