Title: Floating power generation system and support array thereof
Inventor: MA YAQING
IPC: H02S10/40
Filed: 2019-08-01
Abstract: A floating power generation system and a support array of the floating power generation system are provided. The support array has a grid shape, including multiple first coupling beams (1) spaced from each other and multiple second coupling beams (2) spaced from each other. The first coupling beam (1) is connected to the second coupling beam (2). The first coupling beam (1) includes multiple connected floating bodies (11), and the second coupling beam (2) includes multiple connected tubular beams (21). The tubular beams are mounted to the floating bodies (11). The support array of the floating power generation system descried above, has the advantages of both the pure floating body solution and the framework solution in the conventional art, and the support array can overcome the defects of the two solutions. With the above technical solution, high anti-surge capability and compatibility can be ensured, so that the support array has strong applicability in different reg10ns.  Fig. 2

Title: Method and apparatus for variable accuracy inter-picture timing specification for digital video encoding
Inventor: HASKELL BARIN G
IPC: H04N7/26
Filed: 2003-07-11
Abstract: A method and apparatus for variable accuracy inter-picture timing specification for digital video encoding is disclosed. Specifically the present invention discloses a system that allows the relative timing of nearby video pictures to be encoded in a very efficient manner. In one embodiment, the display time difference between a current video picture (105) and a nearby video picture is determined. The display time difference is then encoded (180) into a digital representation of the video picture. In a preferred embodiment, the nearby video picture is the most recently transmitted stored picture. For coding efficiency, the display time difference may be encoded using a variable length coding system or arithmetic coding. In an alternate embodiment, the display time difference is encoded as a power of two to reduce the number of bits transmitted.
