Title: Method for display time stamping and synchronization of multiple video object planes
Inventor: TAN THIOW KENG
IPC: H04N19/46
Filed: 2002-03-26
Abstract: PROBLEM TO BE SOLVED: To provide a method of encoding a local time base embedded in compressed data. SOLUTION: The local time base is encoded in two parts. The 1st part has a modulo time base that indicates the specific interval in the reference time base and the 2nd part has a time base increment relative to the reference time. Two forms of time base increment is used to allow for the possibility of different encoding order and displaying order. A mechanism for the synchronization of multiple compressed streams with local time base is also described. A time base offset mechanism is also used to allow finer granularity synchronization of the multiple compressed streams.

Abstract: <P>PROBLEM TO BE SOLVED: To provide a base isolation foundation structure of a structural body capable of effectively using an existing pile.  <P>SOLUTION: In a foundation beam 4, pile heads of a plurality of existing piles 2 are connected to pile heads of new piles 3. A new structural body 1 is constructed on the upper part thereof. A sliding device 5 is formed on the upper face and connected to the foundation beam 4 through the sliding device 5. The new pile 3 is rigidly connected to the foundation beam 4, but the sectional diameter is set small by a design in which a vertical support force is taken into consideration. Since the bending rigidity is made small by making the sectional diameter small, when a horizontal force larger than a specified force acts on the new pile 3 from the foundation beam 4 by an earthquake or the like, a deflection occurs at the pile head of the new pile 3. Thereby, the pile head displacement becomes large but the sectional area becomes small and the section of the foundation beam 4 can be greatly reduced.  <P>COPYRIGHT: (C)2004,JPO

Abstract: <P>PROBLEM TO BE SOLVED: To provide a laser control circuit that can control the output wavelength of a laser diode with accuracy.  <P>SOLUTION: This laser control circuit 3 is provided with a temperature control circuit 31 and a data processing circuit 302. The temperature control circuit 31 adjusts the temperature of the laser diode 21 by controlling a temperature controller 27.

The circuit 302 first adjusts the temperature of the diode 21 to the temperature value previously made to correspond to a target wavelength. Then the circuit 302 finely adjusts the temperature of the diode 21 in accordance with the output of the wavelength monitor 29. Since the temperature of the diode 21 is roughly adjusted first, it is not required to largely change the output wavelength of the diode 21 in accordance with the output of the monitor 29. Consequently, the periodic wavelength dependency of the output of the wavelength monitor 29 does not lower the control precision of the output wavelength of the diode 21.  <P>COPYRIGHT: (C)2004,JPO
