    Abstract: Methods and apparatus for seamless system management mode (SMM) code injection. A code injection listener is installed in BIOS during booting of the computer system or platform. During operating system (OS) runtime operation a secure execution mode code injection image comprising injected code is received and delivered to the BIOS. The processor execution mode is switched to a secure execution mode such as SMM, and while in the secure execution mode the injected code is accessed and executed on the processor to effect one or more changes such as patching processor microcode, a profile or policy reconfiguration, and a security fix. The solution enables platform changes to be effected during OS runtime without having to reboot the system.

    Abstract: Methods and apparatus relating to encoding Light Detection And Ranging (LIDAR) signals to avoid interference are described. In an embodiment, encode logic encodes a plurality of light beam pulses prior to transmission of the plurality of light beam pulses from at least one light source towards an object. Memory stores encoding information indicative of a type of encoding to be applied to the plurality of light beam pulses. Each of the plurality of light beam pulses comprises one or more sub-pulses. The encode logic is able to cause a modification to at least one of the one or more sub-pulses to encode the plurality of light beam pulses. Other embodiments are also disclosed and claimed.
