20130292146 | DUAL DRIVE FLOOR SCRUBBER - A floor cleaning or burnishing machine has at least one motor controller that is electrically connected to an analog joystick control, right and left potentiometers, an electrical power source, and right and left electrical drive motors. The right motor is mechanically connected to a right rear steering drive wheel and the left motor is mechanically connected to a left rear steering drive wheel. Rotational speed and direction of each rear wheel is independently controlled, by way of the joystick in cooperation with respective potentiometers, in either a forward or reverse direction. At any given time, each potentiometer controls a respective motor controller which individually controls the rotational speed and direction of a respective wheel, thereby each wheel is capable of rotating in an opposite direction at a different speed to the other wheel. To slow the floor cleaning or burnishing machine down, regenerative braking is utilized by operating the motors as generators. | 11-07-2013 |

20140369073 | LIGHTING ASSEMBLY - A lighting assembly includes a light engine and a light guide. The light engine edge lights the light guide and includes a control assembly that controls light output according to one or more parameters to produce light output from the lighting assembly with a desired characteristic. Lighting assemblies are combined to form a modular lighting assembly. | 12-18-2014 |
20150016143 | LIGHTING ASSEMBLY - A lighting assembly includes a light guide having opposed major surfaces between which light propagates by total internal reflection and a light input edge. The light assembly also includes a light engine. The light engine has a heat conductive armature having a receptacle for a portion of the light guide that includes the light input edge and a light source retained by and thermally coupled to the armature. The armature functions as a heat sink for dissipating heat generated by the light source. The light guide is mechanically retained in the receptacle, and the light guide and the armature cooperate to align the light input edge with the light source for inputting light from the light source into the light guide through the light input edge. | 01-15-2015 |
20150092439 | LIGHTING ASSEMBLY WITH ADJUSTABLE LIGHT OUTPUT - A lighting assembly includes a light guide having opposed major surfaces between which light propagates by total internal reflection, a light input edge, and two light output regions of different optical characteristics and at least one of which is associated with a corresponding one of the major surfaces. The lighting assembly also includes a light source located adjacent the light input edge. The light source and the light guide variably positionable relative to one another to vary a location on the light input edge at which the light is input to the light guide such that the light is emitted from the light guide selectively apportioned between the light output regions so that a characteristic of the light output from the lighting assembly is modified based on the optical characteristics associated with the light output regions and the relative positioning of the light source and the light guide. | 04-02-2015 |
20150131310 | LIGHTING ASSEMBLY WITH CONFIGURABLE ILLUMINATION PROFILE - A lighting assembly includes an edge-lit light guide and a light redirecting member.
