| 20080244858 | HAND VACUUM WITH FILTER INDICATOR - A hand-held portable vacuum having a filter indicator that is coupled to an outlet housing and in fluid communication with a portion of the outlet housing between a fan inlet and an intake. The filter indicator includes a pressure differential indicator that is configured to indicate a pressure differential between air in the portion of the outlet housing and atmospheric air pressure. The filter indicator is employed to indicate to the user of the hand-held vacuum that replacement and/or cleaning of the filter is required. The vacuum may also be used in a blower mode with a set of inflator nozzles to permit a user to inflate an article. | 10-09-2008 |
| 20090144931 | Hand-Held Cordless Vacuum Cleaner - A hand-held vacuum cleaner with a container for the storage of dirt and debris therein. To provide improved efficiency and performance, the hand-held vacuum may employ a primary HEPA filter, a device for swirling a dirt and debris laden air flow and/or a mechanized filter cleaning device. Swirling may be employed to direct entrained dirt and debris in a desired direction relative to the container to slow the rate with which dirt and debris accumulates on the primary filter and/or to centrifugally remove dirt and debris from the air flow. Mechanized cleaning is employed to shake, scrape or otherwise remove accumulated dirt and debris from the primary filter. | 06-11-2009 |

| 20090266042 | MOWER - A battery-powered lawn mower includes a deck supported by wheels on a first side and a cutting mechanism having a first motor, including a first output member. A first cutting blade is driven by the first output member. A self-drive transmission has a second motor that selectively communicates an output to a drive axle. A force feedback controller measures a load on the first motor and changes an output voltage to the second motor based on the measured load. | 10-29-2009 |
| 20100051299 | TILLER WITH REMOVABLE BATTERY - A tiller can include a frame supported by at least one wheel. An upright assembly can extend from the frame. A drive mechanism can be supported by the frame and include a motor having an output member. A tilling implement can have a drive shaft that is driven by the output member. The tilling implement can comprise at least one tine plate. A slider assembly can communicate with the wheel and be movably coupled along the upright assembly. The slider assembly can be configured to securably locate in at least a first position wherein the wheel is located at a first elevation relative to the frame and a second position wherein the wheel is located at a second elevation relative to the frame. The first and second elevations can be distinct. | 03-04-2010 |
| 20100275564 | MOWER - A battery-powered lawn mower includes a deck, a latch assembly, a battery, a motor and a blade. The deck is supported by wheels and defines a pocket. The latch assembly is coupled to the deck and is movable between a locked position and a fully opened position. The battery is secured within the pocket by the latch assembly in a first configuration and is removable from the pocket in a second configuration. The motor is supported by the deck and electrically coupled to the battery in the first configuration. The blade is coupled to the deck and driven by the motor. During operation, the battery powers the motor to drive the blade. | 11-04-2010 |
