Abstract: A system for detecting Denial-of-Service (DoS) attacks on one or more user profiles collects a number of invalid sign-on attempts on the one or more user profiles during every time interval. The system determines a number of invalid sign-on attempts on every user profile since the start of the first time interval.

The system detects a third DoS attack on multiple user profiles if the total number of invalid sign-on attempts detected during combined time intervals exceeds a third threshold number.

Abstract: In a corneal measurement system, an optical element focuses an excitation light to an area of corneal tissue at a selected depth. In response, a fluorescing agent applied to the cornea generates a fluorescence emission.

The system may include a scan mechanism that causes the optical element to scan the cornea at a plurality of depths, and the controller may determine a measurement of the fluorescing agent in the cornea as a function of depth.
