Granted: 2001-07-01
Abstract: The present invention relates to a method for improving resolution of indicator's pointer movement by dividing on-screen display (OSD) blocks forming the display screen into several resolution blocks wherein each resolution block is corresponding with a resolution address interval.

Title: Bicycle
Inventor: FUJIWARA NOBUHIRO
IPC: B62M1/24
Filed: 1999-08-02
Granted: 2000-12-01
Abstract: This invention relates to a bicycle having a driving force transmitting mechanism with oscillating fulcrum point. A sliding part is provided with a dust cover or a brush to prevent dust and the like from being entered therein and to remove the dust, if entered, therefrom. When a rider steps on the pedals alternatively, force of the pedal levers generated by the oscillation of the pedal levers is transmitted to the sprocket through the crank lever. When the pedal levers oscillate, an oscillating fulcrum point of the pedal lever is moved in a lateral direction within the sliding part. The rotating force of the sprocket is transmitted to the rear wheel through a chain. Even if the locus Q of motion of the pedal is different in the first half period (a stepping-on period) and the second half period (a stepping-up period), a smooth movement of the pedal is assured. Such a smooth movement can be kept enough by the dust cover.

Title: Method for processing video pictures for display on a display device and apparatus for carrying out the method
Inventor: WEITBRUCH SEBASTIEN
IPC: G09G3/28
Filed: 2000-03-17
Granted: 2003-02-21
Abstract: With the new plasma display panel technology new kinds of artefacts can occur in video pictures due to the principle that brightness control is done with a modulation of small lighting pulses in a number of periods called sub-fields. These artefacts are commonly described as 'dynamic false contour effect'. A technique called bit line repeat coding has been developed for reducing the false contour effect. According to this technique sub-field coding is done with common (CSF) and normal sub-fields (SF) where for the common sub-fields (CSF) identical entries in the sub-field code words of two or more corresponding pixels on two or more pixel lines are used. In this specific sub-field coding method some cases will occur in which an error has to be made due to the reduced flexibility in encoding produced by the need to have the same code on common sub-fields (CSF). The general idea of the invention is now to put the coding failures on the higher video levels of the two or more pixels being grouped together. Further improvements concern picture content analysis and or motion detection for controlling the switching between different sub-field coding modes and a specific adapted dithering pattern for use with bit line repeat coding.
