Abstract: A control mechanism and method using RGB (red-green-blue) light emitting diodes (LEDs) are disclosed. A particular embodiment includes: a red-green-blue (RGB) light emitting diode (LED) having a plurality of color components, each color component being either active or inactive; and an input controller coupled to each of the plurality of color components to determine a voltage level thereon, the input controller being configured to detect a voltage change in an inactive color component when light from an active color component is reflected off of a proximate object.

Abstract: A drinking straw for transferring fluids is provided with a body shaped as a cylindrical tube and one aperture. The body includes a first end, a second end, and an outer surface. Furthermore, the aperture extends from the first end of the body to the second end of the body and the aperture defines an inner surface. Additionally, the straw includes an angle point where the upper region of the straw is displaced at a fixed angle with respect to the lower region. Both the outer surface of the straw and the inner surface have the same non-circular shape.
