Abstract: A material feeding apparatus and method for providing a controlled feed of material. In particular, there is described a material feeding control apparatus and method comprising a feed rate measurement device capable of providing an online mass and/or volume flow measurement of material and a material sensing device capable of providing an online content (e.g. composition) measurement of the material. The material being fed may, for example, be any suitable bulk material including fuel for a combustion chamber (e.g. a furnace), mined materials such as iron ore and food in a food feeding system. A particular example of the present invention is the provision of a fuel feeding apparatus capable of providing substantially stable combustion in a combustion chamber (e.g. a furnace) which may be incorporated into a cement production line.

Abstract: The invention relates to a tool comprising a handle and a tip, which provides amplified tactile feedback to a user regarding the material with which the tip of the tool is in contact. In one embodiment, tactile feedback is provided to the user via the handle of the tool, in the form of movements which correspond at least partially to those experienced by the tip of the tool as it interacts with the material. The tool optionally provides audio and/or visual feedback regarding the material. In a preferred embodiment, the tool is a surgical instrument.

Abstract: The method includes the steps of obtaining atlas data in an atlas coordinate frame from a computer-readable atlas of anatomical information, obtaining patient data in a patient coordinate frame that corresponds to obtained atlas data in an atlas coordinate frame, and morphing atlas data using a first morphing transformation between obtained patient data in a patient coordinate frame and corresponding obtained atlas data in an atlas coordinate frame. The apparatus includes a tracking system for tracking physical objects; a computer for receiving information on tracked objects, a computer program on computer readable medium for operation on the computer.
