Publication number: 20240110841Abstract: Provided are methods and associated apparatus for determining the integrity of a hermetically sealed electronic component. The method and associated apparatus includes the use of an evacuation chamber configured to placing the hermetically sealed electronic component within. The evacuation chamber is then evacuated of atmosphere to then determine an atmospheric pressure evacuation relationship or curve occurring inside the chamber that is, in turn, used to determine the integrity of the hermetically sealed electronic component. Further aspects may include evacuating the chamber through a mass spectrometer coupled to the evacuation chamber for chemical analysis of at least one of the evacuated atmosphere for making further determinations of the integrity of the hermetically sealed electronic component.Type: ApplicationFiled: October 4, 2023Publication date: April 4, 2024Applicant: The United States of America, as represented by the Secretary of the NavyInventors: Brandon Hirsch, Matthew Keller, Stephen Becker, Michael A.

Patent number: 9405124Abstract: In exemplary implementations of this invention, light from a light field projector is transmitted through an angle-expanding screen to create a glasses-free, 3D display. The display can be horizontal-only parallax or full parallax. In the former case, a vertical diffuser may positioned in the optical stack. The angle-expanding screen may comprise two planar arrays of optical elements (e.g., lenslets or lenticules) separated from each other by the sum of their focal distances. Alternatively, a light field projector may project light rays through a focusing lens onto a diffuse, transmissive screen. In this alternative approach, the light field projector may comprise two spatial light modulators (SLMs). A focused image of the first SLM, and a slightly blurred image of the second SLM, are optically combined on the diffuser, creating a combined image that has a higher spatial resolution and a higher dynamic range than either of two SLMs.Type: GrantFiled: April 9, 2014Date of Patent: August 2, 2016Assignee: Massachusetts Institute of TechnologyInventors: Matthew Hirsch, Gordon Wetzstein, Ramesh Raskar, Vincent Lee

Patent number: 9335553Abstract: In exemplary implementations of this invention, two LCD screens display a multi-view 3D image that has both horizontal and vertical parallax, and that does not require a viewer to wear any special glasses. Each pixel in the LCDs can take on any value: the pixel can be opaque, transparent, or any shade between. For regions of the image that are adjacent to a step function (e.g., a depth discontinuity) and not adjacent to a sharp corner, the screens display local parallax barriers comprising many small slits. The barriers and the slits tend to be oriented perpendicular to the local angular gradient of the target light field. In some implementations, the display is optimized to seek to minimize the Euclidian distance between the desired light field and the actual light field that is produced. Weighted, non-negative matrix factorization (NMF) is used for this optimization.Type: GrantFiled: August 26, 2015Date of Patent: May 10, 2016Assignee: Massachusetts Institute of TechnologyInventors: Douglas Lanman, Matthew Hirsch, Yun Hee Kim, Szymon Jakubczak, Ramesh Raskar

Patent number: 8848006Abstract: In exemplary implementations of this invention, an automultiscopic display device includes (1) one or more spatially addressable, light attenuating layers, and (2) a controller which is configured to perform calculations to control the device. In these calculations, tensors provide sparse, memory-efficient representations of a light field. The calculations include using weighted nonnegative tensor factorization (NTF) to solve an optimization problem. The NTF calculations can be sufficiently efficient to achieve interactive refresh rates. Either a directional backlight or a uniform backlight may be used. For example, the device may have (1) a high resolution LCD in front, and (2) a low resolution directional backlight. Or, for example, the device may have a uniform backlight and three or more LCD panels. In these examples, all of the LCDs and the directional backlight (if applicable) may be time-multiplexed.Type: GrantFiled: January 8, 2013Date of Patent: September 30, 2014Assignee: Massachusetts Institute of TechnologyInventors: Gordon Wetzstein, Douglas Lanman, Matthew Hirsch, Ramesh Raskar

Patent number: 8651678Abstract: In exemplary implementations of this invention, a flat screen device displays a 3D scene. The 3D display may be viewed by a person who is not wearing any special glasses. The flat screen device displays dynamically changing 3D imagery, with a refresh rate so fast that the device may be used for 3D movies or for interactive, 3D display. The flat screen device comprises a stack of LCD layers with two crossed polarization filters, one filter at each end of the stack. One or more processors control the voltage at each pixel of each LCD layer, in order to control the polarization state rotation induced in light at that pixel. The processor employs an algorithm that models each LCD layer as a spatially-controllable polarization rotator, rather than a conventional spatial light modulator that directly attenuates light. Color display is achieved using field sequential color illumination with monochromatic LCDs.Type: GrantFiled: November 29, 2012Date of Patent: February 18, 2014Assignee: Massachusetts Institute of TechnologyInventors: Douglas Lanman, Gordon Wetzstein, Matthew Hirsch, Wolfgang Heidrich, Ramesh Raskar

Patent number: 8654234Abstract: A bidirectional screen alternately switches between a display mode showing conventional graphics and a capture mode in which the LCD backlight is disabled and the LCD displays a pinhole array or a tiled-broadband code. A large-format image sensor is placed behind the liquid crystal layer. Together, the image sensor and LCD function as a mask-based light field camera, capturing an array of images equivalent to that produced by an array of cameras spanning the display surface. The recovered multi-view orthographic imagery is used to passively estimate the depth of scene points from focus.Type: GrantFiled: November 20, 2009Date of Patent: February 18, 2014Assignee: Massachusetts Institute of TechnologyInventors: Matthew Hirsch, Ramesh Raskar, Henry Holtzman, Douglas Lanman
