181 results about "Site location" patented technology

The site is the actual location of a settlement on the earth and is composed of the physical characteristics of the landscape specific to the area. Site factors include things like landforms, climate, vegetation types, availability of water, soil quality, minerals, and even wildlife.

Method and system for providing site independent real-time multimedia transport over packet-switched networks

Embodiments of the invention enable minimum latency site independent real-time video transport over packet switched networks. Some examples of real-time video transport are video conferencing and real-time or live video streaming. In one embodiment of the invention, a network node transmits live or real-tine audio and video signals, encapsulated as Internet Protocol (IP) data packets, to one or more nodes on the Internet or other IP network. One embodiment of the invention enables a user to move to different nodes or move nodes to different locations thereby providing site independence. Site independence is achieved by measuring and accounting for the jitter and delay between a transmitter and receiver based on the particular path between the transmitter and receiver independent of site location. The transmitter inserts timestamps and sequence numbers into packets and then transmits them. A receiver uses these timestamps to recover the transmitter's clock. The receiver stores the packets in a buffer that orders them by sequence number. The packets stay in the buffer for a fixed latency to compensate for possible network jitter and/or packet reordering. The combination of timestamp packet-processing, remote clock recovery and synchronization, fixed-latency receiver buffering, and error correction mechanisms help to preserve the quality of the received video, despite the significant network impairments generally encountered throughout the Internet and wireless networks.

Transmission project site and line selecting method based on GIS space information

Disclosed is a transmission project site and line selecting method based on GIS space information. According to coordinates of an area to be selected of a transformer substation and a line design end point, integrated optimization is carried out on the transformer substation and the line. The method comprises the steps of (1) meshing the area to be selected of the site location of the transformer substation, (2) removing the infeasible area of the site location of the transformer substation, (3) automatically generating an initial path of the line of a site location plot, (4) automatically sorting preliminary schemes of the transformer substation line based on the GIS, (5) performing scene investigation, and verifying and optimizing the line path, (6) performing statistic on to-be-compared schemes of the transformer substation line, and (7) performing technical skill comparing and result outputting. According to the site location selection and line path integrated optimizing method based on the GIS space information, the difficulty of manually selecting the site location and the line path at present is avoided, and the functions of automatic selection and sorting of the site location of the transformer substation, automatic generating of the path, statistic of path length and the number of corners, judgment of line complex terrain, technical skill comparing and the like can be achieved.
