Efficient navigation of autonomous carriers
InactiveUS7206677B2Effective strategyMinimize energy consumptionSuction cleanersSpecial data processing applicationsComputation complexityEngineering
According to the invention, autonomous carriers or vehicles are efficiently navigated over a field of operation. The carriers are equipped to execute a selected procedure at more than one desired location on the field, and the navigation system of the invention directs the carrier to the location that is preferentially accessible to it, based on a defined criterion. After the carrier has executed the selected procedure at the location which is preferentially accessible to it, the navigation system directs the carrier to the location which is preferentially accessible to the carrier from the carrier's new position. This procedure is repeated until all the locations at which the procedure is to be executed have been reached. The task of determining a navigation route to a location that can be preferentially accessed is based on an efficient, structured search procedure of low computational complexity.

Handheld vacuum with accelerated cyclonic flow and air freshener
A hand held vacuum having a tapered centrifugal chamber as its primary filter. The tapering causes the air stream within the centrifugal chamber to accelerate as it moves toward the distal end. The air steam will be able to retain more debris at higher speeds, thereby improving the efficiency of the centrifugal chamber. This will also keep more of the debris in the vicinity of the distal end of the centrifugal chamber and away from its outflow aperture. An air freshener in a filter housing is also provided. The air freshener will sublimate into the passing air stream and be emitted with the exhaust from the vacuum and / or any odor causing particles that may be in the air stream will be absorbed by the air freshener. The filter will prevent any dust and debris in the airstream from adhering to the air freshener and impeding its effectiveness.

Obstacle sensing system for an autonomous cleaning apparatus
An obstacle-sensing system for carriers, particularly autonomous carriers such as robot vacuum cleaners, enables the carriers to disengage themselves from any obstacle or obstruction with which they come into physical contact and proceed past the obstacle or obstruction. The obstacle-sensing system is established by constructing a carrier to have front and rear sections which, normally, are in a neutral relationship with respect to one another but which move relative to one another when the front section physically engages an obstacle or obstruction. The relative movement activates a guidance and control system that maneuvers the carrier around the obstacle or obstruction.
