Abstract: A method and apparatus for stitching the edges of adjacent strips (12) or swaths printed by a strip or swath printer in a manner which reduces the effects of visual artifacts caused by a difference in print quality, density or shape between pixels at or near the edge of the adjacent strips and other pixels in the strips. Two adjacent strips, each having a number of lines, are printed such that a portion (16) of one or more lines in one of the strips (12a) overlaps a portion (16) of a corresponding number of lines in the other strip (12b), with the pixels in corresponding overlapping line portions being superposed. When the strips are printed, certain predetermined pixels in all or some of the line portions in each of the two strips (12a, 12b) which will overlap are not printed. The pixels not to be printed may be selected such that the border or boundary between the adjacent edges of the two overlapping strips forms a nonlinear, predetermined pattern, such as a regular, repeating pattern, e.g., triangular, or a random or pseudo-random pattern. As a result of this process, overlapping line portions contain a mixture of pixels of higher and lower density or quality, thus reducing the effects of the visual artifacts caused by the clear contrast between such higher and lower density pixels when strips are not overlapped.

Abstract: This invention provides apparatus and a method which will self-adjust the pressure response of a digitizer pointing device (12) or other device incorporating a pressure transducer (34) according to the characteristics of the particular device and/or particular user of the device. For example, a simulated paint brush and in simulated chalk, or, the user may use the stylus device (12) entirely differently when using it in a game or in a graphic arts application, or different users may use the same stylus device (12) differently for the same application. Certain pressure parameters of the device are not set on a fixed basis, which would provide for an average, typical or generic pressure range and/or sensitivity of the device are automatically, or semi-automatically adjusted to provide a suitable pressure range and maximum resolution for the particular user.

Abstract: A stylus (20) for use with a digitizer tablet (21) has a tip element (32) that includes a front portion with a tip (32a) for engaging the surface of the tablet (61), and a back portion of the tip element (32b) within the stylus housing (30). The back portion of the tip element (32b) is adapted to apply pressure to a pressure sensitive resistance element (41). The front and back portions of the tip element (32) are coupled together by a spring (35), in order that the tip element (32) be resiliently compressible in the axial direction of the stylus.

Abstract: A ribbon cassette (10) for a thermal printer (14) is disclosed. The cassette (10) shown in the figure is configured to be stably mounted to a print carriage (16) of a thermal printer (14), or to a storage turret (34) mounted to the printer (14) for storing a number of cassettes (10), and to be transferred by a passive transfer system between the print carriage (16) and the storage turret (34) simply in response to movement of the print carriage (16). A smooth, low friction path is provided for the ribbon (12) within the cassette (10) with no acute angle changes in the path when the cassette (10) is in a printing position and being acted upon by the printer's print head (24). The cassette (10) is provided with a brake mechanism (120), which automatically engages the supply and take-up reels in the cassette when the cassette is removed from the print carriage, and automatically disengages the brake mechanism (120), when the cassette (10) is mounted to the print carriage (16).

Abstract: Motor-driven cutting apparatus for cutting sheet media are disclosed, particularly for use with plotter and printer apparatus. The cutting apparatus of one embodiment comprises two cutting members (26, 27) in which at least one of the cutting members (26) is moved both angularly and linearly, e.g., pivoted and reciprocated, relative to the other to cut media placed between the two cutting members. In another embodiment, the cutting members (126, 127) are both simultaneously pivoted relative to each other. Rotary motion of a driving member, e.g. a motor shaft (16) or a shaft coupled to a motor shaft, is converted to combine angular and straight line motion or only angular motion at one or both cutting members by a simplified coupling arrangement which may comprise simple sleeves with eccentric structure (39, 90) and pivot-type joints. Cutting apparatus according to the invention may be used for X-axis and/or Y-axis cutting.

Abstract: An electromagnetic digitizer tablet having an active region (110) comprising an array of conductors (1-15) having plural, spaced, similar active portions (111, 112) regularly and uniformly distributed throughout the active tablet region, together with additional structure to distinguish pointing device (130) positions over the similar active portions. This arrangement reduces the number of individual conductors required. In a preferred arrangement, the active portions have a block S shape. As a further feature, novel algorithms are used to calculate the fine location of the pointing device.
