Title: Pivotal sheet support mechanism for inkjet printer
Inventor: KELLY KIERAN B
IPC: B41J13/14
Filed: 1998-03-12
Abstract: The pivot mechanism 86 (Fig.11) is coupled to a feed roller 66 and supports a sheet fed thereto by a first feed roller 64. The mechanism which includes a support surface and arms 100 (Fig.14), is intermittently movable between a first position 94 (Fig.13) and a second position 96 (Fig.11). During printing the lead edge 88 (Fig.13) of the sheet moves from the support surface onto rails 74 above an output tray 72. This motion continues until the trailing edge 108 (Fig.13) of the sheet is detected by a sensor 170. At this point, the pivot moves from the first position to an intermediate position 136 (Fig.14). Consequently, the pivot arms 100 extend to a first height above the support surface and the rails retract upwards. The sheet drops from the rails and is pushed by the arms from the support surface towards the tray. The motion of the pivot, rails and arms may be interrupted (e.g. paused and/or reversed) at this position. Subsequently, the pivot moves to the second position which causes the rails to retract fully and the arms to extend fully to a second height above the surface to push the sheet onto the tray.

Title: Image serialisation for image object persistence
Inventor: CLARK DAVID
IPC: G06F9/44
Filed: 1998-03-18
Abstract: Java (RTM) development Toolkit version 1.1x (JDK) does not support the serialisation of images, but does allow primitive data types to be serialised, that is, primitive data type objects, including objects comprising primitive data type components, can be written to a file or another area of memory, before an application closes; when the application reopens, the primitive data types can be de-serialised and so recovered. According to this invention, an image object is converted into a primitive data type object and then serialised so that the image object can also be made persistent. In a preferred embodiment, the image object is converted to an array of integers representing the image pixels; a colour table of unique integers is created from the integer array; each integer in the integer array is converted into an index in the colour table; and the combined colour table and array of indices are compressed before serialisation.
