    • A system and method to support platform firmware as a trusted process. Measurement of a trusted portion of original firmware are measured by a core root of trust measurement (CRTM). The measurement is stored in a secure manner during pre-boot. During operating system (OS)-runtime, requests are made to access an unqualified current version of firmware corresponding to a secure execution mode. A portion of the current firmware analogous to the trusted portion is measured. The measurements of the trusted original portion and unqualified current portion are compared to verify they match. If they match, it indicates that the current portion and the trusted portion are one in the same. Thus, the current portion of firmware is trustworthy. Accordingly, the firmware may be executed as a trusted process. Embodiments employ locality to enforce the trusted process. The use of locality prevents unqualified users (i.e., software) from accessing data stored by trusted firmware.
    • 将平台固件支持为可信过程的系统和方法。 原始固件的受信任部分的测量是通过信任测量(CRTM)的核心根来测量的。 在预引导期间,以安全的方式存储测量。 在操作系统(OS) - 运行时期间,请求访问对应于安全执行模式的不合格的当前版本的固件。 测量与可信部分类似的当前固件的一部分。 比较可信原始部分和不合格的当前部分的测量结果,以验证它们是否匹配。 如果它们匹配,则表示当前部分和可信部分是相同的。 因此,固件的当前部分是值得信赖的。 因此,固件可以作为可信过程来执行。 实施例采用本地来强制可信过程。 使用本地防止不合格用户(即,软件)访问由可信固件存储的数据。

    • A rotary steerable drilling tool with an electromagnetic steering system can include a drill collar, a bit shaft, an orientation control module, a mud tube, a mud tube coupler, a universal joint, a mud sealing device, and a drill bit. The bit shaft can be mechanically coupled to the drill collar through the universal joint and the orientation control module and rotate about the universal joint. The orientation and the inclination angle of the bit shaft against the drill collar can be controlled by the orientation control module with the electromagnetic steering system. The orientation control module can include an array of electromagnets, an array of permanent magnets, a rotor, and a set of bearings. The orientation control module can be coupled to the bit shaft through the rotor. The movement of the rotor can be driven by the interaction between the array of electromagnets and the array of permanent magnets.

    • The present invention provides an access method and a system for a Machine-Type Communication (MTC) device, and an MTC device. The method comprises the steps of: an MTC device sending, when performing channel request, a channel request cause value and a random reference value to a Base Station Subsystem (BSS) (100), and the BSS sending the received channel request cause value and random reference value back to the MTC device when completing channel allocation (101). The present invention distinguishes the MTC services from other non-MTC services through the channel request cause value, that is, when the cause values are different, the collision will not occur even if the random reference values are the same, thus reducing the probability of the random reference value collision, implementing the effective management for access operations of large numbers of MTC devices, and avoiding the influence of random reference value collision on the normal implementation of original services.
    • 本发明提供了一种用于机器类型通信(MTC)设备和MTC设备的访问方法和系统。 所述方法包括以下步骤:MTC设备在向基站子系统(BSS)(100)发送信道请求原因值和随机参考值时,发送所述接收的信道请求导致值,并且 随机参考值在完成信道分配时返回给MTC设备(101)。 本发明通过信道请求原因值来区分MTC服务与其他非MTC服务,即当原因值不同时,即使随机参考值相同也不会发生冲突,从而降低了 随机参考值碰撞,实现大量MTC设备接入操作的有效管理,避免随机参考值碰撞对原始业务正常实现的影响。
