A device for directly electrically generating and detecting the current-generated spin polarization in topological insulators, comprising a first and fourth contact on a layer of BiSeand a second contact comprising a ferromagnet/oxide tunnel barrier contact as a detector, and a third contact comprising nonmagnetic metal as a reference contact, a current to the first and fourth contact to produce a net spin polarization, and the spin polarization manifesting as a voltage between the second (magnetic) and third (reference) contacts.

Direct electrical detection of current-induced spin polarization due to spin-momentum locking in topological insulators

In various embodiments, a color gamut mapper includes a gamut map selection generator configured to analyze color space signals and generate a gamut map selection signal in response thereto. A color gamut transformer is configured to process the color space signals via a selected one of a plurality of gamut maps to generate gamut mapped color space signals, wherein the selected one of the plurality of gamut maps is selected in response to the gamut map selection signal. Other embodiments are disclosed.

Color gamut mapper for dynamic range conversion and methods for use therewith

A method for directly electrically generating and detecting spin polarization in topological insulators comprising depositing a first and fourth contact on a layer of BiSeand applying a current between the contacts, which creates a net spin polarization due to spin-momentum locking. A second (comprising ferromagnet/tunnel barrier) and third contact are deposited for detecting the spin polarization. A device for directly electrically generating and detecting the current-generated spin polarization in topological insulators, comprising a first and fourth contact on a layer of BiSeand a second contact comprising a ferromagnet/oxide tunnel barrier contact as a detector, and a third contact comprising nonmagnetic metal as a reference contact, a current to the first and fourth contact to produce a net spin polarization, and the spin polarization manifesting as a voltage between the second (magnetic) and third (reference) contacts.

In various embodiments, a filtering tone mapper includes a two-dimensional filter. A tone mapper configured to apply tone mapping to a video frame in accordance with a tone mapping function to generate a processed video frame, wherein the tone mapper operates in conjunction with the two-dimensional filter to apply the tone mapping to pixels of the video frame based on a plurality of adjacent pixels of the video frame. Other embodiments are disclosed.

Tone mapper with filtering for dynamic range conversion and methods for use therewith

Encoding video data that includes a frame includes: generating a reconstructed frame from compressed data for the frame, partitioning at least some pixels of the reconstructed frame into a plurality of segments of one or more pixels, based at least in part on pattern information for individual pixels, and generating respective filter information for each of one or more of the plurality of segments. Encoded video data is generated that includes the compressed data for the frame and the generated filter information.
