Abstract: Apparatus, system and method for providing pressurized infusion of liquids and, more particularly, providing a stable and pressurized flow of fluid to the eye during surgery. Aspiration fluid may be received via an aspiration line at a first peristaltic pump, where aspiration fluid is transferred to a Venturi tank reservoir coupled to a second peristaltic pump. Fluid from a fluid source is provided via a third peristaltic pump to a pressurized infusion tank. A determination is made if the pressure in the pressurized infusion tank is at a predetermined level, where fluid may be transferred from the pressurized infusion tank to an irrigation line when pressure in the pressurized infusion tank is determined to be at the predetermined level. Alternate activation of a plurality of aspiration and irrigation lines are also provided.

Abstract: This disclosure relates to a method in which points common to two or more of the images that appear to represent the same real world features are identified, and changes in the location of the points between respective images are used to deduce the motion of the camera and to find the position of the real world features in three dimensional space. In order to determine the scale of the three dimensional information, the position of a reference feature, whose actual distance from the camera is known, is found from the images. The reference feature is found by considering only candidate points selected from candidate points falling within a portion of the image corresponding to a part of the field of view of the camera. The scale is determined from the distance between the camera and the reference feature in the image and in real life.

Abstract: A method and system for identification of obstacles near railways and for providing alarm to an operator of a train if obstacles constitute threat to the train are disclosed. The system comprise IR sensor disposed at the front of the train facing the direction of travel. The IR sensor receives images of the rails in front of the train. The system comprises pre-stored vibration profile of the train's engine that is used to eliminate influence of the engine's vibrations on the accuracy of the received images. Presence of rails in the received frames is detected based on inherent differences of temperature between the rails and the substrate in the rails' background, such as the railway sleepers and the materials underneath it. The system may detect defects in an electric conductor system of a train.
