Abstract: A system, e.g., a system on a chip (SoC) includes a first domain including a first processor configured to boot the system; a second domain including a processing subsystem having a second processor; and isolation circuitry between the first domain and the second domain During boot-up of the system, the first processor provides code to the second domain. When the code is executed by the second processor, it configures the processing subsystem as either a safety domain or as a general-purpose processing domain. The safety domain may an external safety domain or an internal safety domain.

Abstract: Technology is described for methods and systems for a diffractive optic device (525) for holographic projection. The diffractive optic device can include a lens (535) configured to convey a hologram. The lens (535) further comprises a patterned material (510) formed with an array of cells having a non-planar arrangement of cell heights extending from a surface of the patterned material. The lens further optionally comprises a filling material (530) to fill gaps on both surfaces of the patterned material.

Abstract: An imaging system that is translucent can be achieved by placing an image sensor (204) at one of more edges or periphery of a translucent window (202). A small fraction of light from the outside scene scatters off imperfections (218) in the translucent window (202) and reach the peripheral image sensor (204). Based on appropriate calibration of the response of point sources (206) from the outside scene, the full scene can be reconstructed computationally from the peripherally scattered light (210, 212). The technique can be extended to color, multi-spectral, light-field, 3D, and polarization selective imaging. Applications can include surveillance, imaging for autonomous agents, microscopy, etc.

The dispersed sensor image (215) can represent a spatial code of the intermediate image (235).

Abstract: A multi-modal imaging device can include a sensor array, a metamaterial filter, and a memory unit. The sensor array can be any suitable sensor which detects incoming light and is capable of recording a received image. The metamaterial filter can be oriented adjacent the sensor array and can be patterned with pixels having varied physical heights designed to diffract an incoming image to produce an engineered response which is sensitive to 2D spatial coordinates (x, y), time (t), and at least one of depth spatial coordinate (z), spectrum (?), and degree of polarization ({right arrow over (S)}). The memory unit can include instructions that, when executed by a processor, reconstruct the engineered response to produce a reconstructed image which includes the 2D spatial coordinates and at least one of z, ?, and {right arrow over (S)}.

A camera can capture emission such as fluorescence resulting from the optical stimulation. A cannula configured for implantation into a subject can be configured to direct the emission from the subject. A mating sleeve coupling the cannula to the optical fiber, and configured to support the camera, can include a dichroic mirror to allow the optical stimulation to pass from the optical fiber to the cannula and to redirect the emission from the cannula to the camera.

Abstract: A spectral distribution of incident light can be determined to increase collected spectral information. The spectral distribution of the incident light can be represented as a sum of spectral components after the incident light passes through a spectrum selective element. A signal at each color pixel of the spectrum selective element can be determined using, in part, the sum of the spectral components, where the spectral components are represented by a set of preliminary values. An error associated with the signal at each color pixel of the spectrum selective element is calculated. One or more perturbations are performed on each of the preliminary values and the error associated with the signal at each color pixel of the spectrum selective element is recalculated. The perturbations on each of the preliminary values is repeated until the error stabilizes within a predetermined range in order to assign the stabilized preliminary values as the spectral components in the incident light.
