Abstract: A battery boost apparatus is described. The battery boost apparatus monitors that amount of voltage in the vehicle battery and the current flowing to the vehicle battery to determine an existence of a fault condition. If a fault condition exists, a vehicle battery is cutoff from the boost battery and the charge of the boost battery is maintained until the fault condition is remedied.

Abstract: 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.

Abstract: A battery pack with a housing, at least one battery cell contained within the housing, a first terminal and a second terminal. The housing includes a substantially ovoidal surface which is substantially symmetric about a first axis of symmetry and a second axis of symmetry which is transverse to the first axis. The surface has first and second substantially linear terminal openings. The first opening extends substantially parallel to and is non-coincident with the first axis, while the second opening extends substantially parallel to the second axis. The first and second terminals are disposed within the housing adjacent to the surface. The first terminal is accessible through first opening and the second terminal is accessible through the second opening. A device for using the battery pack is also provided.

Abstract: 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.

Abstract: A cordless mower, including a start-up key that must be removed to charge a battery. The start-up key must be inserted to operate the motor, and can be moved to a different position or removed to interrupt the motor. The mower cannot be operated when the switch is not actuated. Some embodiments include a lockout relay that disables charging of the battery when a charge on the battery exceeds a predetermined threshold. Thus, the cordless mower can be safely charged by removing the start-up key and inserting a charge connector that cannot otherwise be inserted. The cordless mower can be safely powered by inserting the start-up key and moving it into an operation position, and then closing the switch to run the mower. The cordless mower can be safely shut off in an emergency by removing the start-up key or moving it to a safety position.

Abstract: A hand held steam vacuum is provided that is operated by way of a single switch device. The vacuum is generally comprised of a vacuum fan, a water pump, a heating element, and a fluid supply tank in fluid communication with a fluid discharge outlet. In operation, the vacuum fan is operable to suck debris into a collection bowl residing in the vacuum. In addition, the water pump is operable to drive fluid from the fluid supply tank via fluid transport tubes to the fluid discharge outlet, and the heating element is operable to heat the fluid prior to it being discharged from the fluid discharge outlet. A single switch device is configured to control operation of the vacuum fan, water pump and heating element.

Abstract: A housing assembly for a power edger that includes a housing, a door and a latching system. The door is coupled to the housing and movable between an open position and a closed position. The latching system includes a latch member that is coupled to one of the housing and the door and a ramp that is coupled to the other one of the housing and the door. Contact between the ramp and the latch member when the door is being closed against the housing causes the latch member to move to an unlatched condition so as to automatically align the latch member to a latch aperture. This permits the door to be fully closed without the need to manually operate the latch member.
