Abstract: A marking device is disclosed. In at least one embodiment, a marking device having a refillable, washable marking composition for use on food containers, and the like, that is food-safe and non-toxic includes: a housing, elongated and generally cylindrical in form and having a hollow interior channel; a marking composition disposed within the hollow interior channel of the housing, the marking composition consisting of a natural wax; a fatty acid; and a toner; and a marker tip removably coupled to the housing to receive the marking composition within the housing as it is extended outwardly for use.

Abstract: A plurality of organic light emitting diode (OLED) devices can be spatially distributed to form various lighting systems and luminaires. The lighting systems can be configured to readily replace conventional light bulbs or tubular fluorescent lamps. A networked lighting system including a plurality of OLED devices can have a variable light field based on a feedback.

Abstract: An organic light emitting diode (OLED) device includes a substrate, an anode, a cathode, an active region including an organic material, wherein the active region is electrically coupled to the anode and the cathode, at least one coupler configured to electrically couple at least one of the anode or the cathode to a power supply, and an encapsulation that isolates the active region from an ambient environment. A lighting system can be made including a plurality of OLED devices. A lighting system can be assembled using the OLED devices from a kit. The OLED devices may be polymer light emitting diode (PLED) devices or small molecule light emitting diode (SMOLED) devices. The OLED devices can use regio-regular poly-thiophene.

Abstract: A lighting system includes a plurality of organic light emitting diode (OLED) devices. By selecting the plurality of OLED devices, or by selectively controlling the plurality of OLED devices, the color characteristics of the lighting system can be tuned. The lifetime of the lighting system can be improved.
