Title: Fibre channel credit extender and repeater
Inventor: GEORGE WILLIAM R
IPC: H04B10/299
Filed: 2000-12-11
Granted: 2010-06-22
Abstract: The Fibre Channel Credit Extender (FCCE) (600) is a network device that is disposed between and connected to an end node (210) and an optical repeater (220). The FCCE (600) contains as many buffer credits as necessary, to solve bandwidth problems in a network. In a situation where maximum bandwidth is required in both directions of a link, the FCCE (600) breaks a single logical link into three physically separated "linklets". The short-distance linklets attain maximum bandwidth by use of the existing buffer credits of the end nodes. The long-distance linklet attains maximum bandwidth by use of very high receive buffer credits in the FCCEs (600). In this way, only those links that need maximum bandwidth over distances not covered by end-node credit counts need be attached to an FCCE (600). The FCCE (600) contains the optical repeater to gain distance on that link, and contains high credit count receive buffers to gain bandwidth on the link. All other ports of the switch can have smaller and less expensive receive buffers.

Abstract: A method for measuring an optical system comprises transmitting an image with the optical system. Gradients of the optical system can be determined by separating the transmitted image with a lenslet array. An error-correcting change in the shape of the optical system can be mapped by integrating across the gradients (76). The change in elevation around the path (96) is related to the accuracy of the gradient array. A system for measuring a wavefront of an eye includes an image source for projecting an image into the eye, lenslets, a detector for measuring angles of light rays of an optical surface (34) of an eye, and a computer for mapping the errors of the eye. A tomographic wavefront map is made by deflecting the measurement path of the wavefront sensor.  Aberrations are selected for treatment in response to an order of the aberration and a tissue structure corresponding to the aberration.
