20090017230 | Corrosion-resistant internal coating method using a germanium-containing precursor and hollow cathode techniques - Enhanced corrosion resistance is achieved in a coating by using a germanium-containing precursor and hollow cathode techniques to form a first layer directly on the surface of a workpiece, prior to forming an outer layer, such as a layer of diamond-like carbon (DLC). The use of a germanium or germanium-carbide precursor reduces film stress and enables an increase in the thickness of the subsequently formed DLC. Germanium incorporation also reduces the porosity of the layer. In one embodiment, a cap layer containing germanium is added after the DLC in order to further reduce the susceptibility of the coating to chemical penetration from the top. | 01-15-2009 |

20090035483 | APPARATUS FOR DIRECTING PLASMA FLOW TO COAT INTERNAL PASSAGEWAYS - An apparatus for coating surfaces of a workpiece configured to establish a pressure gradient within internal passageways through the workpiece, so that the coating within the internal passageways exhibits intended characteristics, such as those relating to smoothness or hardness. The coating apparatus may include any or all of a number of cooperative systems, including a plasma generation system, a manipulable workpiece support system, an ionization excitation system configured to increase ionization within or around the workpiece, a biasing system for applying a selected voltage pattern to the workpiece, and a two-chamber system that enables the plasma generation to take place at a first selected pressure and the deposition to occur at a second selected pressure. | 02-05-2009 |

20150276144 | Low-Profile Outdoor Lighting Module With Light Emitting Diodes - A low-profile lighting module with light-emitting diodes (LEDs) has a water-tight seal between a molded-plastic cover and a printed circuit board (PCB). A substrate with the LEDs fits up into an indentation in the lower surface of the PCB. Landing pads on the top of the substrate attach to contact pads in the indentation that are extensions of a conductor of the PCB which is electrically coupled through the landing pads to the LEDs. A lens with a curved optical portion surrounded by a flat lip fits into another indentation on the upper surface of the PCB. A highly reflective sheet is disposed between the planar lower surface of the lens and bottom of the indentation in the upper surface. A double-sided adhesive sheet is disposed under the inside surface of the molded-plastic cover and over both the upper surface of the PCB and the flat lip of the lens. | 10-01-2015 |

20110249437 | HIGHLY EFFICIENT LED ARRAY MODULE WITH PRE-CALCULATED NON-CIRCULAR ASYMMETRICAL LIGHT DISTRIBUTION - A light module includes a light emitting diode (LED) array and a double-reflective assembly coupled to the LED array. The double-reflective assembly includes a lower member having a frame. The frame has an opening corresponding to the LED array. The frame and LED array are located in the same plane. The light module further includes a left bottom reflector and a right bottom reflector. The light module further includes an upper member which includes a left top reflector; and a right top reflector, wherein the left top reflector is attached to the left bottom reflector, and right top reflector is attached to the right bottom reflector, each forming an arbitrary left and right double-reflective assembly. A shape geometry and profile of each double-reflective assembly provides a pre-calculated combined non-circular asymmetrical intensity distribution pattern. The intensity distribution pattern is a superposition of light reflected from the bottom reflectors, light reflected from the top reflectors, light doubly reflected from both the top and bottom reflectors, and light directed into the intensity distribution pattern directly from the LED array. | 10-13-2011 |
