## Title
Vibration cancelling platform for use with laptops or table computers used in moving vehicles

## Abstract

Use of a laptop, tablet or other electronic device within a vehicle or other mode of transportation is often made difficult due to vibration, bumps and sudden turns. A vibration cancelling platform provides stabilization to an electronic device used during transportation. A platform may be comprised of a top housing and a bottom housing which may slide laterally relative to each other in order to stabilize a user's electronic device resting upon the top housing. Low friction sliding components such as rollers, bearing or other components help to reduce or prevent the environmental movement experienced by the bottom housing from being transmitted to the upper housing. Spring elements secured between the top and bottom housings further assist in reducing vibration and act to stabilize the top housing in a centralized position. Optional mouse pads extend from the platform by use of specially configured low friction sliding mechanisms.

BRIEF SUMMARY OF THE INVENTION
Using a laptop computer or other device while traveling may be challenging due to vibrations, shaking, turns and bumps that are typically encountered while riding in cars, buses, RVs, trains, airplanes and other modes of transportation. More specifically, a table mounted to a moving vehicle may act as a cantilever and amplify vibrations to laptop computer sitting upon the table. Whether resting upon a table or a user's lap, a laptop computer is typically subjected to unpleasant movement that hinders the use of the computer and concentration of the user. In many modes of transportation it is nearly impossible to view a laptop screen and use a keyboard and mouse due to the abrupt accelerations, decelerations, vibrations and other movements.
The presently disclosed embodiments solve long felt shortfalls in the art by presenting an unobvious and unique combination, configuration and use of components to provide a portable vibration canceling platform for use with laptop computers and other devices used in mobile environments. Disclosed embodiments mitigate and/or cancel vibrations or shaking that typically occurs to computers used upon tables mounted to a vehicle.
The presently disclosed embodiments overcome shortfalls in the art by presenting a new platform or device that comprises a bottom housing artfully connected to a top housing such that the two housings enjoy nearly unrestricted lateral motion with respect to one another. Shortfalls in the art are further overcome by use of centering components, such as springs and elastic members that gently return the top housing to a neutral position and absorb movement transmitted to the bottom housing. Optional extendable mouse pads further add to the utility of the disclosed embodiments.
Embodiments include the use of rollers, roller support journals, bumpers, springs or elastic members and other components advantageously configured.
An alternative embodiment roller journals are replaced by rollers, with the rollers in direct rolling contact with the underside of a top housing and top side of a bottom housing. An especially compact design is achieved by use of guide plate that guides and separates the rollers in lieu of a cage and race configuration.
