    摘要： Systems and techniques for privacy protected input-output port control are described herein. In an example, an indication may be obtained that a protected port is disabled. A set of application attributes stored in a secure memory location may be compared to a set of attested application attributes to create a verification flag. At least one port attribute of the protected port may be obtained based on the verification flag. The protected port may be enabled using the at least one port attribute. Other examples, for controlling an input-output port using computer firmware and trusted execution techniques are further disclosed.

    摘要： The architecture and techniques described herein can improve system performance with respect to the following. Communication between two interdependent hardware engines, that are part of pipeline, such that the engines are synchronized to consume resources when the engines are done with the work. Reduction of the role of software/firmware from feeding each stage of the hardware pipeline when the previous stage of the pipeline has completed. Reduction in the memory allocation for software-initialized hardware descriptors to improve performance by reducing pipeline stalls due to software interaction.

    摘要： An apparatus for secured playback is presented. In one embodiment, the apparatus includes a controller that includes a key derivation module to manage authentication and key derivation. In one embodiment, the apparatus provides a video decryption key to a graphics engine if video data portions in a data stream are retrievable without having to decrypt the data stream. In one embodiment, the apparatus also includes a decryption module to decrypt a part of data in conjunction with an encryption key to generate video information and video data. The controller then writes an encrypted version of the video data to a video buffer of a graphics engine.

    摘要： A medical attachment device position detection system for use during medical training including a processor and a medical attachment device communicatively coupled to the processor, a first magnetometer coupled to the medical attachment device and configured to detect a first angle, and a second magnetometer configured to detect a second angle. The second magnetometer is communicatively coupled to the processor. The processor is operably configured to compare a relationship of the first angle relative to the second angle to determine a position of the medical attachment device relative to a subject.

    摘要： A tracking system and method for tracking a medical attachment device relative to a subject including at least a first reflector defining a first tracking region. The tracking system includes a medical attachment device having at least one reflector sensor operable to integrate the first reflector. A processor is communicatively coupled to the medical attachment device. The processor is operable to determine a distance between the medical attachment device and the first tracking region to determine a location of the medical attachment device relative to a subject.
