Title: Coding method of interlace scanned digital video signal
Inventor: LUCAS FUI YOU WAI
IPC: H04N19/50
Filed: 2002-03-28
Abstract: PROBLEM TO BE SOLVED: To efficiently code an interlace scanned video sequence. SOLUTION: An input image (1) is divided into small blocks of pixel data (2), and two fields in each block are inspected in terms of correlation (3). When the difference between the two fields in the block is small (high correlation), the block is coded by using the frame-coding method for successively scanning all lines in the blocks, hence the inter-frame movement compensation method for efficient design, and color data intra-frame sub sampling method (6). Conversely, when the difference between the two fields in the block is large (namely, low correlation) the block is coded by a field-coding process for intensifying the investigation of the (intra-field) correlation in each field, and the (inter-field) correlation between each field and the adjacent field (5).

Title: Fuel cell system and control method for the system
Inventor: NAKANISHI HARUMICHI
IPC: H01M8/04
Filed: 2002-04-19
Abstract: <P>PROBLEM TO BE SOLVED: To prevent a cross leak when the connection of the output terminals of a stack to a load is disconnected.  <P>SOLUTION: The control device of this fuel cell system disconnects the connection of both output terminals of the FC stack to the load when a load requirement is zero (step S110). The area of a fuel gas passage near an inlet is closed (step S120), and the blow of oxidized gas is stopped (step S130). By this, the hydrogen gas remaining in the FC stack at the time of OCV becomes an amount generally equal to the volume of the fuel gas passage. Then, both output terminals of the FC stack are shortcircuited (step S140). Since the remaining hydrogen gas is consumed, cross leaking is not produced after the short- circuiting. Though a heat is produced at the time of the short-circuiting, since the residual amount of hydrogen gas is less than before, a heating amount is less to provide no adverse effect.  <P>COPYRIGHT: (C)2004,JPO
