Patent number: 10459138Abstract: An embedded wire-grid polarizer (WGP) can include ribs 13 located over a surface of a transparent substrate 11, gaps 16 between the ribs 13, and a fill-layer 15 substantially filling the gaps 16. The fill-layer can have a relatively high index of refraction, such as greater than 1.4. At a wavelength of light incident upon the WGP, E? transmission can be greater than E? transmission. E? is a polarization of light with an electric field oscillation parallel to a length L of the ribs, and E? is a polarization of light with an electric field oscillation perpendicular to a length L of the ribs. This embedded, inverse WGP is especially useful for polarizing, with high WGP performance, small wavelength (high-energy) regions of the electromagnetic spectrum (e.g. UV) which are difficult to polarize with conventional WGPs (E? transmission >E? transmission).Type: GrantFiled: January 24, 2019Date of Patent: October 29, 2019Assignee: Moxtek, Inc.Inventors: Ted Wangensteen, Bin Wang, Matt George, Paul Steven Mills, Arash Farhang

Patent number: 9485133Abstract: DCMI functionality is extended to platforms of a datacenter by integrating a management controller in each of plural platforms and interfacing the management controllers with a management server through a network. End users interface with platforms of the datacenter using DCMI protocol communications. The management server supports communication with management controllers by receiving DCMI messages and translating the DCMI messages to a text-based protocol for communications with the management controllers. In one embodiment, the management controllers push sensor information for their associated platforms to a sensor cache of the management server so that the management sensor references the cache to respond to DCMI requests for sensor information.Type: GrantFiled: March 26, 2012Date of Patent: November 1, 2016Assignee: Dell Products L.P.Inventors: German Florez-Larrahondo, Jimmy D.

Patent number: 9144179Abstract: An immersion cooling tank comprises: a dielectric liquid disposed within a lower volume of the tank; at least one electronic equipment immersed within the dielectric liquid and which requires electrical power to operate; and at least one power distribution unit and/or a bus bar distribution system submerged beneath a surface of the dielectric liquid and providing electrical power to the at least one electronic equipment. The immersion cooling tank further includes a condenser located vertically above the dielectric fluid and the at least one electronic equipment, and through which is flowing a condensation fluid that has a lower density than the dielectric liquid. A leak of the condensation fluid into the tank volume results in the condensation fluid floating atop the dielectric liquid and prevents the condensation liquid from coming into contact with the power distribution unit. The bus bar distribution system enables blind mating of inserted electronic components.Type: GrantFiled: February 1, 2013Date of Patent: September 22, 2015Assignee: Dell Products, L.P.Inventors: Austin Michael Shelnutt, James D.
