20090046246ELECTROMAGNETIC BEAM DETECTION SYSTEM - The present invention provides for a Line of Sight (LOS) electromagnetic beam (EM) detection system configured with an enclosure, a detection device, a processing device, a storage device, and a communication device. The enclosure may or may not be electromagnetically shielded from the surrounding environment. The enclosure may contain one or more detection devices and one or more portals configured for a user to look through. The detection devices may be a non-contacting, active-dry electroencephalogram (EEG) electrode or a high input impedance EEG electrode. The processing device may be a specifically programmed general purpose computer. The communication device may be auditory and/or visual. The storage device may store signals from the detection device for later analysis and statistical manipulation. In some embodiments, the LOS detection system may be used as a switch responding to interaction with a LOS beam emanating from an ocular cavity.02-19-2009
20090079935Method of Calculating the Required Power of a Toric Implant - A method for calculating the required power of a toric implant by using both the measured pre-operative corneal astigmatism and the predicted surgically-induced post-operative astigmatism. The surgically-induced post-operative astigmatism is predicted using power vector analysis of the surgical technique employed by the surgeon. Such a method provides a more accurate method of calculating the required post-operative refractive power of the implant. The method can be implemented manually, but preferably is automated by implementation on a computer through appropriate software.03-26-2009
