Abstract: A cordless digitizer system (10) is disclosed which comprises a digitizer tablet (11) and a cordless pointing device (12) which cooperate to provide to the tablet information relating not only to the position of the pointing device relative to the tablet, but also relative to the status of any switches (37, 38) on the pointing device. The pointing device (12) generates and radiates to the tablet (11) first and second signals (23, 24) of different frequencies. The first and second signals are radiated from the pointing device (12) at a third frequency (30) which contains information of the status of the switch. For example, one of the signals may be radiated relatively continuously or both of the signals may be alternatingly radiated at the third frequency in dependence upon the status of the switches. The first and second signals induce corresponding signals in the tablet which are processed to provide respective signals at the third frequency. These signals are then processed to obtain the status of the pointing device switches. Switch status information can also be binary encoded as a particular sequence of alternations of the first and second signals.

Abstract: A digitizer tablet which employs low pass filtering (27) of raw coordinate data to reduce noise (31) and jitter. A weighted filtering (23) is employed, in which the new position data is averaged with a previous average or previous position data before being reported. The weighting factor applied to the new data is determined by the degree of monotonicity (20) represented by the data, with intentional movements of the pointing device indicating high monotonicity undergoing light filtering but noise indicating low monotonicity undergoing heavy filtering (21).

Abstract: A compliant skirt (26) is provided for use with a large plotter (10) and media (14) being plotted upon. The skirt (26) is attached to a platen means (18) of the plotter (10) and complies or flexes in response to the moving media (14) and follows the media (14)as it moves over the skirt (26). Such compliance of the skirt helps maintain close contact between the media (14) and compliant skirt (26) which prevents separation of the media (14) from the skirt (26) and thereby eliminates formation of media waves. In addition, compliance of the skirt (26) absorbs energy associated with excess motion of the media (14) which reduces tugging loads.

Abstract: A novel thermal "strip mode" printing method and apparatus are disclosed. Data representing the image (26) to be printed is arranged in a plurality of X-axis strips (34-38) each having a Y-axis width substantially less than the width of the medium (27) to be printed on, i.e., each strip is substantially less in width than the width of the medium (27) to be printed upon so that a number of strips are necessary to print across the full width of the medium. Each strip may have a Y-axis width of from about 1 inch to about 4 inches. The strip mode thermal print head (28) is moved to an X-axis strip, then the medium (27) is moved to print in the strip. The strip mode print head (28) remains stationary while the medium (27) is moved to print an entire strip. The strip mode print head is next moved to print in another strip and held stationary while that strip is printed. Also disclosed are a Y-axis drive system (64) for moving the print head (28) and accurately positioning it in the strips (34-38), a stationary platen (76) having a resilient contact surface (280) supported on a rigid base (282) which has excellent straightness, and support for the print head which rotates about a pitch axis parallel to the Y-axis and about a roll axis.

Abstract: A digitizer tablet (10) providing hysteresis compensation in which the X and Y coordinates of a pointing device (20) are measured at different times. In order to enable the tablet (10) to report X and Y coordinates that when displayed will more accurately reflect the pointing device (20) movements, a correction algorithm, built, for example, into the controlling software, estimates and reports what the first measured coordinate (69) would have been, measured when the second coordinate is measured, based upon the calculated velocity and acceleration of the pointing device (20). A similar technique can be used to correct the reported value of the second coordinate. In a preferred embodiment, constant coefficients of a linear equation having as variables three consecutive coordinate values or three consecutive preprocessed coordinate values are predetermined and used in the correction algorithm. The preferred embodiment integrates the velocity and acceleration hysteresis compensation into a three point recursive noise filter (83).

Abstract: Disclosed herein are position determining apparatus (130) and conductor structures (172) or grids therefor. The conductor structure (40) for each axis includes a number of conductors (50) which are run in a serpentine-type path each with uniform repeat increment. The repeat increment, which is the spacing or span between one run and the next of the same serpentine-type conductor, are uniform for each conductor (but may change from conductor to conductor) and is constrained by a maximum repeat increment, or a minimum repeat increment. In the preferred embodiments, there is at least a constraint on the maximum repeat increment to provide noise immunity. The conductors are arranged for each axis of the grid in a pattern such that signals obtained for that axis may be processed to provide binary numbers in a Gray-type code, each unique to a small region of the active area in which the coil center is located.

A multi-head printhead is also disclosed capable of producing different sized dots to replace pens of different tip size. Also disclosed is a structure for providing the constant printing distance, a mechanism for maximizing ribbon life and control arrangements for providing desirable line quality.
