    Considers using inverse solutions for determining source locations. Dipole source localization using EEGs recorded from the scalp is widely used to make estimates of the locations of sources of electrical activity in the brain. Such information can be very useful for both clinical and research applications. For example, in clinical applications, accurate information about the location of an epilep... View full abstract»

  • The perils of picking a trademark

    Publication Year: 1998

    As anyone who has done it knows, picking a trademark is hard to do. First, there are the marketing considerations-a good mark can make a good product or service sell even better. Then there are the legal issues. Some marks are not entitled to legal protection (e.g., generic marks) and others are not available because they are already being used by others. One common procedure to determine the avai... View full abstract»

    This article summarizes the theoretical underpinnings of both the forward and inverse problems of electrocardiography. Space limitations prohibit describing all of the research work done in these areas, and the author apologizes in advance for any omissions on this account or due to oversight. The article should enable one to gain a better qualitative and quantitative understanding of the heart's ... View full abstract»
