    摘要： One embodiment of the writing instrument described herein comprises a pen-like device containing three accelerometers and three gyroscopes. Data from these sensors are processed via an Euler transform. Prior to using the writing instrument, the user holds the writing instrument in multiple predefined positions and sensor readings are taken. The sensor readings are mapped to the corresponding predefined positions. In addition, the sensor readings are compared to expected sensor readings to compensate for environmental variations such as altitude or temperature as well as for the possible tilt of a writing surface. The sensor readings are interpolated to map sensor readings other than those at the predefined positions to other writing instrument positions. When the user writes with the writing instrument, sensor outputs are used to track the writing instrument to define strokes made by the user. The data describing the strokes may be stored or processed to accomplish a variety of tasks including faxing a message, recording information, etc.

    摘要： A method and apparatus to precisely track the position of the writing instrument, specifically the writing end, such as the tip, of a pen. One embodiment of the invention described herein includes a writing instrument containing acceleration sensors and angular velocity sensors. Data from these sensors are processed via an Euler transform to determine the strokes made with the writing instrument. Corrections may be made to improve upon the output of the Euler transform. The data describing the strokes may include graphical representations of the strokes actually made with the writing instrument. Data describing the strokes may be stored or processed to accomplish a variety of tasks such as recording information, faxing a message, recording an appointment, or other such tasks.

    摘要： Apparatus for stacking a plurality of laminate layers in registered superposed relation to enable the layers to be joined to form a composite board comprising a table having a surface on which a plurality of laminate layers can be successively stacked in aligned superposed relation on pins slidably received in respective apertures in the table. The pins rest on support members which are carried on a lower support table mounted beneath the surface of the table on which the laminate layers are stacked. The lower support table is raised relative to the stack of laminate layers after successive laminate layers have been placed on the pins so that a given projection of the pins from the laminate layers will be obtained.
