Patent number: 8888315Abstract: This invention provides a vapor-tight luminaire with a housing that defines a continuous and unbroken sealed tubular lens extending in a longitudinal direction. The housing includes a pair of end cap structures removably and sealably mounted on each of opposing respective housing ends. The housing removably supports a lamp assembly that can include various reflector arrangements. The lamp assembly can include fluorescent tubular lamps and can include electronics, such as a ballast circuit. Illustratively, a supporting rail suspended from each of the opposing housing ends by respective posts slidably supports the lamp assembly. In this manner each of the housing and the lamp assembly are constructed and arranged to allow the lamp assembly to be passed into and out of the housing along the supporting rail when at least one of the end cap structures is removed from the respective one of the housing ends.Type: GrantFiled: May 24, 2012Date of Patent: November 18, 2014Assignee: Greendot Technologies, LLCInventors: Richard D. Edwards, Stanley A. Katz

Patent number: 8616730Abstract: This invention provides a vapor-tight luminaire that maintains a moisture-proof, sealed lower housing for the light-producing lamps (fluorescent lights, LED arrays, etc.) while isolating the electronic components in a separate, upper housing that is spaced apart from, and largely thermally isolated from, the lamps. The lamp housing comprises a unitary non-penetrated tubular lens with one or more removable end caps, sealed by gaskets. The lamp assembly is slidably mounted within the lower housing so that it is readily removable and replaceable with another assembly of the same or different type. The electronics in the upper housing is readily accessible and replaceable by removing a top cover that encloses a three sided channel member. The upper housing is metal and desirably enhances heat exchange with the environment. The two housings are held together by a pair of opposing end cap structures that include a housing end and a removable end cap.Type: GrantFiled: March 7, 2011Date of Patent: December 31, 2013Assignee: Greendot Technologies, LLCInventors: Richard D.

Patent number: 7731609Abstract: A golf green repair tool with a depth limiting feature that has an earth engagement surface that has a forward slant to reposition the raised portion around a crater to the center region of the crater. A prong portion is adapted to be thrusted toward the center region of the crater and the repair tool is adapted to do minimal damage to the turf mat and provides a desirable method to repair craters left by impacting golf balls by properly repositioning of the displaced portions.Type: GrantFiled: April 25, 2007Date of Patent: June 8, 2010Assignee: Greenfix Golf, Inc.Inventors: Terry G.

Patent number: 7588347Abstract: This invention provides a lighting fixture for use in low-ceiling applications and/or outdoor environments, such as parking garages that allows for the use of more-efficient lighting sources, such as fluorescent lamps, with more-even distribution of light along the sides of the fixture so that the surrounding space is fully and efficiently illuminated. Two elongated light sources are mounted upon opposing sides, and surrounded by a pair of respective side reflectors. The side reflectors direct the light of the two light sources in a generally sideward and somewhat-downward direction. The lower portion of the side reflectors collectively define an overall wide angle and each lower portion completely overlies a respective one of the side light sources mounted above. A third light source can be located centrally, beneath the lower portions to provide downward light, which is further reflected generally downwardly by the wide angled lower portions.Type: GrantFiled: April 15, 2008Date of Patent: September 15, 2009Assignee: GreenDot Technologies, LLCInventor: Richard D. Edwards, Jr.

Patent number: 7131753Abstract: This invention provides a high-output industrial light fixture that employs a plurality of commercially available fluorescent light sources in an array of adjustable arm assemblies each housing one or more light sources (fluorescent bulbs) in an associated reflector box or other source housing structure. By adjusting the arm assemblies, a more-precise spread of light onto the target surface can be achieved. Arm mounting brackets can be provided with one or more locking positions to facilitate multi-position angular placement of each individual arm. A plurality of arm assemblies can be provided around a center housing or hub, each directed outwardly in a radial direction from a central point or axis of the center housing/hub. Each arm's source reflector box/source housing structure can be located to project light either downwardly or upwardly and can be angled at a plurality of angular adjustment positions with respect to the center housing in each of the upward and/or downward positions.Type: GrantFiled: May 10, 2004Date of Patent: November 7, 2006Assignee: Edwards Enterprises, LLCInventor: Richard D.

Patent number: 6815232Abstract: A method includes measuring a first overlay error between a first process layer and a second process layer using a first overlay target formed on the second process layer. A second overlay error between the first process layer and a third process layer is measured using a second overlay target formed on the third process layer. At least one parameter of an operating recipe for performing a photolithography process on the first process layer is determined based on the first and second overlay error measurements. A system includes a metrology tool and a controller. The metrology tool is configured to measure a first overlay error between a first process layer and a second process layer using a first overlay target formed on the second process layer and measure a second overlay error between the first process layer and a third process layer using a second overlay target formed on the third process layer.Type: GrantFiled: November 26, 2002Date of Patent: November 9, 2004Assignee: Advanced Micro Devices, Inc.Inventors: Gary K Jones, Christopher A Bode, Richard D Edwards
