Abstract: A laser level disposable on a reference surface includes a housing, a laser diode disposed within the housing for emitting a laser beam along a path, a lens disposed in the path for converting the laser beam into a planar beam. The planar beam thus forms a line on the reference surface. The laser level also includes an electronic distance measurement circuit disposed within the housing for measuring distance. The distance measurement circuit including a display for showing the measured distance.

Abstract: A tape measure includes a housing, a rule blade coilable within the housing, and a light plane generator disposed on the housing. The light plane generator may include a laser source for emitting a laser beam and a line lens in the path of the laser beam for converting the laser beam into a laser plane. Preferably, the laser plane intersects both the rule blade and a workpiece. The light plane generator may be pivoted about a horizontal axis and/or a vertical axis.

Abstract: An improved laser level has a housing and a first shaft connected to the housing. Two bearings are disposed on the first shaft. A gimbal body is disposed on the two bearings. A second shaft is connected to the gimbal body. A third bearing is disposed on the second shaft. A pendulum is disposed on the third bearing. A laser diode is disposed on the pendulum.

Abstract: A line generating device may include a housing, a support assembly mounted within the housing, a light source mounted on the support assembly, a lens mounted on at least one of the support assembly and the light source, the lens receiving light and projecting the light in the shape of a fan within a plane, and a first level vial mounted on the support assembly, wherein the first level vial is coplanar or perpendicular to the plane. The device may also include a magnet mounted on the support assembly.

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.

Abstract: A vacuum cleaner system having an electric powerhead with a first switch actuator component which can be actuated with a user's thumb, to turn on and off the powerhead, and a second switch actuator component which can be actuated with the user's foot, to also turn on and off the powerhead. The first switch actuator component is used when the powerhead is being used in a handheld cleaning mode. The second switch actuator component is used when the powerhead is being used in a floor cleaning mode along with an upright handle attached to the powerhead. An anti-tip over lockout system is incorporated for preventing the powerhead from being accidentally turned on when it is being held in an upside down orientation, such as during cleaning of a beater brush thereof.
