摘要:
Method for streaming video content from a video server entity to a client entity via a core network and an aggregation network connected through an edge node. The server entity can be either the origin server or a serving node in a CDN that acts as a surrogate server. The video content is offered by the video server entity as a set of consecutive fragments (or chunks or segments), each fragment of this set of consecutive fragments being offered in a plurality of quality levels corresponding to respective encoded bit rates. The method comprises the steps of: transmitting via the network from said client entity to said video server entity via said edge node one or more requests for fragments with a target quality level of said video content to be displayed at said client entity; and receiving at said client entity via said network one or more replies to the requests containing fragments with said target quality levels. The method further comprises the steps of said edge node evaluating the available throughput for said client entity to transmit said fragments to said client entity over said aggregation network and said edge node informing said client entity about said available throughput.

A method of treating a solid matrix containing organic contaminants is provided. The method comprises the steps of a) injecting ozone into the solid matrix for a period of time known as the pulse duration; b) interrupting the injection of ozone into the solid matrix for a period of time known as the gap duration; and c) repeating step a) at least one additional time. Gap durations of from about 2 hours to about 48 hours are disclosed. Pulse durations of from about 0.25 hours to about 8 hours are also disclosed. Recalcitrant organic contaminants are treated.
摘要:
A system for calculating one or more dimensions of an animal. The system comprises at least three fiducial reference points, each having different X, Y, and Z coordinates in 3-dimensional space. In addition, the system further comprises at least two sensors for obtaining dimensional measurements of the fiducial reference points and the animal from at least two different fields of view. In one embodiment, the at least two different fields of view are at least a side view and a top view. The system also comprises a processing system configured to receive the dimensional measurements from the at least two sensors and calculate one or more dimensions of the animal by relating positions of animal features to known locations of the fiducial reference points. The system also may create and measure a 3-dimensional image of the animal.

摘要:
A telephone mouthpiece and earpiece cover system for helping protect a user from contact from germs on a telephone. The system includes an earpiece cover attachment and a mouthpiece cover attachment. The earpiece cover attachment comprises a base having a plurality of holes extending therethrough. The front surface of the base of the earpiece attachment has an annular lip extending around the outer perimeter of the base of the earpiece cover attachment. The back surface of the base of the earpiece cover attachment has a perimeter wall defining a space adapted for inserting the earpiece of a telephone therein. The mouthpiece cover attachment comprises a top with a plurality of apertures extending therethrough. The back surface of the top of the mouthpiece cover attachment has an annular wall, which defines a space adapted for inserting a mouthpiece of a telephone therein.
