  • Amide compounds for treatment of complement mediated disorders
    Patent number: 10428094
    Abstract: Compounds, methods of use, and processes for making inhibitors of complement factor D comprising Formula I, or a pharmaceutically acceptable salt or composition thereof, wherein R12 or R13 on the A group is an amide substituent (R32) are provided. The inhibitors described herein target factor D and inhibit or regulate the complement cascade at an early and essential point in the alternative complement pathway, and reduce factor D's ability to modulate the classical and lectin complement pathways. The inhibitors of factor D described herein are capable of reducing the excessive activation of complement, which has been linked to certain autoimmune, inflammatory, and neurodegenerative diseases, as well as ischemia-reperfusion injury and cancer.

  • Stabilization and rolling shutter correction for omnidirectional image content
    Patent number: 10397481
    Abstract: Techniques are described for addressing rolling shutter delay and in some cases rolling shutter delay and stabilization. Processing circuits may receive image content in overlapping portions of images, and may adjust the image content until there is overlap in the overlapping portions. Processing circuits may also receive information of deviation of the device from a common reference. Based on the overlapping image content, the deviation of the device from the common reference, and image content in non-overlapping portions, the processing circuits may determine mapping of coordinates to a rectangular mesh for generating an equirectangular image.

  • Memory interface for a Secure NOR Flash Memory
    Publication number: 20190129638
    Abstract: A flash memory controller is operative to receive serial commands and command arguments. A flash permissions table identifies each segment of flash memory as READ_ONLY, PRIVATE_R/W or OPEN_R/W. A memory interface is coupled to a flash memory and also the flash permissions table. When a flash memory write operation is received with an associated command argument corresponding to an address indicated as READ_ONLY in the flash permissions table and a DISABLE_WR_REG is true, the write operation is ignored or converted into a non-write command and issued to the flash memory.
