Abstract: The present invention provides an improved RTSP protocol. Concepts and components similar to the SIP proxy server are introduced into conventional RTSP architecture. RTSP proxy server not only can assist RTSP media server under NAT firewall in positioning location and ensure that it can keep the RTSP channel connection but also provide the service about NAT port prediction. Furthermore, a brand new method about TCP traversal through NAT is applied in the improved RTSP in order to solve the peer to peer problem when the client and RTSP media server are both under NAT.

Abstract: A chromatic confocal microscope system and signal process method is provided to utilize a first optical fiber module for modulating a light into a detecting light passing through a chromatic dispersion objective and thereby forming a plurality of chromatic dispersion lights to project onto an object. A second optical fiber module conjugated with the first optical fiber module receives a reflected object light for forming a filtered light, which is split into two filtered lights detected by two color sensing units for generating two sets of RGB intensity signals, wherein one set of RGB intensity signals is adjusted relative to the other set of RGB intensity signals. Then two sets of RGB intensity signals are calculated for obtaining a maximum ratio factor. Finally, according to the maximum ratio factor and a depth relation curve, the surface profile of the object can be reconstructed.

Abstract: Rectangular-shape resonators as guard traces formed in a region between the victim and aggressor lines are disclosed. No shorting-vias or resistors are required. The rectangular resonators are found to have functions of improving far-end crosstalk (FEXT) and timing jitter in both frequency domain and time domain if the parameters are appropriated selected.
