摘要： A monoscopic imaging system, for example a minimally invasive surgery imaging system, is provided which includes an image capture device for capturing images of a monoscopic, for example endoscopic, field of view, an auxiliary light source operable such that an object within the field of view casts a shadow, an image processor operatively connected to the image capture device and operable to detect shadow pixels in the images corresponding to the shadow and to enhance the shadow in the images. The system is of particular, although not exclusive, application to laparoscopic surgery.

摘要： Subchannel feedback is provided from a plurality of mobile devices to a base station in a communication system, in which a channel is divided into available subchannels. The base station first requests channel information from the mobile devices, and then receives the channel information, for example in the form of an average Effective Signal to Noise Ratio for the channel. Based on the received channel information, the base station selects a subset of the mobile devices, i.e. the best mobile devices. The base station then requests subchannel information relating to a subset of the available subchannels, from the selected subset of the mobile devices, and receives the subchannel information in the form of information identifying said subset of the available subchannels, without indicting a quality of said subset of the available subchannels.
