Abstract: A cleaning device has an elongated handle attached to a housing. The housing includes a stationary brush extending through the housing. Also, the housing includes a rotatable brush, as well as a debris collector. In a first position the cleaning device is used as a conventional broom. The handle is pivoted to a second position which enables the broom to be used as a debris collector.

Abstract: A line generating device may include a housing having a bottom surface, a top surface, a front surface connecting the top and bottom surfaces, a rear surface connecting the top and bottom surfaces, and a side surface connecting the top and bottom surfaces, a support assembly mounted within the housing. In addition, the device may include a light source mounted on the support assembly, and a lens for receiving light and projecting the light in the shape of a fan within a plane. The light plane exits through the front surface. The device is disposable on a reference surface on the bottom, rear and side surfaces.

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.
