    Abstract: The invention provides novel equipment packages, principally for portable equipment such as laptop computers, which provide decoupling, damping and shock isolation of acceleration sensitive components within the packages. Two principal embodiments are disclosed. In the flexible shell embodiment, a plurality of flexible fillers are attached to a flexible shell and a plurality of objects or components are attached to the fillers. In the flexible chassis embodiment, a plurality of objects or components are mounted to the flexible chassis to form an assembly and a plurality of flexible fillers are attached to the chassis to form the complete package. One design methodology employs a decoupled simple harmonic oscillator (SHO) model to optimize the shock response behavior. A second design methodology uses a deterministic method (finite element method) to establish the parameters for the filler and shell materials.

    Abstract: A stylus and tablet X-Y data input system for a video display system. The pen comprises an optical stylus having suitable pickup means and the tablet is passive in nature and provides direct digitized data readout. Absolute positional information is encoded in binary form in the tablet in such a fashion that the pen position upon the tablet is automatically determinable by illuminating a particular area of the tablet and reading off the digitized X-Y coordinate data stored therein. The pen and supporting hardware/software are rotationally insensitive so that the pen may be held in any desired position comfortable to a user. The system provides greatly improved resolution, sampling rate accuracy and general robustness particularly for such applications as text recognition as well as a wide variety of other graphical input uses.

    Abstract: THE INVENTION PROVIDES NOVEL EQUIPMENT PACKAGES, PRINCIPALLY FOR PORTABLE EQUIPMENT SUCH AS LAPTOP COMPUTERS(800), WHICH PROVIDE DECOUPLING, DAMPING AND SHOCK ISOLATION OF ACCELERATION SENSITIVE COMPONENTS WITHIN THE PACKAGES. TWO PRINCIPAL EMBODIMENTS ARE DISCLOSED. IN THE FLEXIBLE SHELL EMBODIMENT, A PLURALITY OF FLEXIBLE FILLERS(108, 112) ARE ATTACHED TO A FLEXIBLE SHELL(101) AND A PLURALITY OF OBJECTS OR COMPONENTS(102-106) ARE ATTACHED TO THE FILLERS. IN THE FLEXIBLE CHASSIS EMBODIMENT, A PLURALITY OF OBJECTS OR COMPONENTS(802-812) ARE MOUNTED TO THE FLEXIBLE CHASSIS(801) TO FORM AN ASSEMBLY AND A PLURALITY OF FLEXIBLE FILLERS(814-822) ARE ATTACHED TO THE CHASSIS TO FORM THE COMPLETE PACKAGE. ONE DESIGN METHODOLOGY EMPLOYS A DECOUPLED SIMPLE HARMONIC OSCILLATOR (SHO) MODEL TO OPTIMIZE THE SHOCK RESPONSE BEHAVIOR. A SECOND DESIGN METHODOLOGY USES A DETERMINISTIC METHOD (FINITE ELEMENT METHOD) TO ESTABLISH THE PARAMETERS FOR THE FILLER AND SHELL MATERIALS.
