    • A system and method to extract heat energy from underground heat sources, then transport that heat to the surface in the form of a high temperature liquid or gas, and deliver the contaminant-free heat energy to a surface user of heat. The heat captured in the working fluid of the system is gained by heat transfers and can be extracted from the in situ combustion of any oil sands, heavy oil, conventional or unconventional oil, bitumen, coal, conventional or unconventional natural gas, methane or oil shales, or from various other sources. The invention creates a closed circulation system, in which the working fluid and steam circulating in the system are protected from any direct contact with the hydrocarbon reservoir, and gases produced by the in situ combustion are sequestered in the reservoir by the overlying overburden.

    • A method is provided for determining optimum positions in a region for a plurality of sensors that are capable of detecting occurrence of a hazard in the region. The hazard may be a chemical, biological, and/or radiological hazard in solid, liquid or gas form. A “simulation cache” is provided that stores data representing interaction of the hazard with sensors at each of the plurality of candidate locations in the region for each of the plurality of sensor types. Data is then retrieved from the simulation cache as needed for evaluation a particular candidate sensor solution comprising one or more sensors of one or more sensor types at corresponding ones of the candidate locations. An optimization algorithm may be used to select a candidate sensor solution. The data that is retrieved from the simulation cache for a selected candidate sensor solution is evaluated with respect to certain performance criteria. The simulation cache greatly reduces the time required to generate an optimum sensor layout because it separates the hazard modeling and sensor performance modeling from the optimization algorithm. By capturing this data at one time for storage in the simulation cache, it is not necessary to re-run the hazard simulations for each candidate sensor location generated by the optimization algorithm.
    • 提供一种用于确定能够检测该区域中的危险的发生的多个传感器的区域中的最佳位置的方法。 危害可能是固体,液体或气体形式的化学,生物和/或放射危害。 提供了一个“模拟高速缓存”,其将针对多个传感器类型中的每个的多个候选位置中的每一个的传感器存储表示危险的相互作用的数据。 然后根据需要从仿真高速缓存中检索数据,以评估包括候选位置中相应一个的一个或多个传感器类型的一个或多个传感器的特定候选传感器解决方案。 可以使用优化算法来选择候选传感器解决方案。 根据某些性能标准评估从所选候选传感器解决方案的模拟高速缓存中检索的数据。 仿真缓存大大减少了生成最佳传感器布局所需的时间,因为它将危害建模和传感器性能建模与优化算法分开。 通过一次捕获该数据以存储在模拟高速缓存中,不需要重新运行由优化算法生成的每个候选传感器位置的危险模拟。

    • Systems, apparatuses, and methods are provided for whitening and managing data for storage in non-volatile memories, such as Flash memory. In some embodiments, an electronic device such as media player is provided, which may include a system-on-a-chip (SoC) and a non-volatile memory. The SoC may include SoC control circuitry and a memory interface that acts as an interface between the SoC control circuitry and the non-volatile memory. The SoC can also include an encryption module, such as a block cipher based on the Advanced Encryption Standard (AES). The memory interface can direct the encryption module to whiten all types of data prior to storage in the non-volatile memory, including sensitive data, non-sensitive data, and memory management data. This can, for example, prevent or reduce program-disturb problems or other read/write/erase reliability issues.

    • In an embodiment, a timer unit may be provided that may be programmed to a selected time interval, or wakeup interval. A processor may execute a wait for event instruction, and enter a low power state for the thread that includes the instruction. The timer unit may signal a timer event at the expiration of the wakeup interval, and the processor may exit the low power state in response to the timer event. The thread may continue executing with the instruction following the wait for event instruction. In an embodiment, the processor/timer unit may be used to implement a power-managed lock acquisition mechanism, in which the processor is awakened a number of times to check the lock and execute the wait for event instruction if the lock is not free, after which the thread may block until the lock is free.
    • 在一个实施例中,可以提供可以被编程到所选择的时间间隔或唤醒间隔的定时器单元。 处理器可以执行等待事件指令,并为包括指令的线程输入低功率状态。 定时器单元可以在唤醒间隔期满时发送定时器事件,并且处理器可以响应于定时器事件而退出低功率状态。 线程可以在等待事件指令之后的指令继续执行。 在一个实施例中,处理器/定时器单元可以用于实现功率管理的锁获取机制,其中处理器被唤醒多次以检查锁定并且如果锁不是空闲的则执行等待事件指令, 之后,线程可能会阻塞,直到锁定为空。
