摘要： An energy harvester system (EHS) for converting a multiple degree of freedom (MDF) pendulum motion into a rotational motion is provided. The EHS includes a pendulum, a pointing element, and motion control slots (MCSs) enclosed in an external housing. Ambient motion from the external housing generates a MDF pendulum motion in the pendulum. The pointing element is slidably positioned on a rod of the pendulum. The MCSs receive a connector that connects the pointing element to the rod of the pendulum and allow the connector to traverse the MCSs, thereby controlling slidable movement of the pointing element along with the pendulum. When the pendulum moves to first ends of the MCSs, the pointing element slides on the rod to allow a pointer of the pointing element to contact and rotate a gear, thereby converting the MDF pendulum motion into a rotational motion of the gear, which drives an electric generator.

摘要： Small and power-efficient buffer/mini-cache sources and sinks selected DMA accesses directed to a memory space included in a coherency domain of a microprocessor when cached data in the microprocessor is inaccessible due to any or all of the microprocessor being in a low-power state not supporting snooping. Satisfying the selected DMA accesses via the buffer/mini-cache enables reduced power consumption by allowing the microprocessor (or portion thereof) to remain in the low-power state. The buffer/mini-cache may be operated (temporarily) incoherently with respect to the cached data in the microprocessor and flushed before deactivation to synchronize with the cached data when the microprocessor (or portion thereof) transitions to a high-power state that enables snooping. Alternatively the buffer/mini-cache may be operated in a manner (incrementally) coherent with the cached data. The microprocessor implements one or more processors having associated cache systems (such as various arrangements of first-, second-, and higher-level caches).

摘要： Power conservation via DRAM access reduction is provided by a buffer/mini-cache selectively operable in a normal mode and a buffer mode. In the buffer mode, entered when CPUs begin operating in low-power states, non-cacheable accesses (such as generated by a DMA device) matching specified physical address ranges are processed by the buffer/mini-cache, instead of by a memory controller and DRAM. The buffer/mini-cache processing includes allocating lines when references miss, and returning cached data from the buffer/mini-cache when references hit. Lines are replaced in the buffer/mini-cache according to one of a plurality of replacement policies, including ceasing replacement when there are no available free lines. In the normal mode, entered when CPUs begin operating in high-power states, the buffer/mini-cache operates akin to a conventional cache and non-cacheable accesses are not processed therein. In one usage scenario, data retained in the buffer/mini-cache is graphics refresh data maintained in a compressed format.

摘要： Embodiments of the present disclosure provide techniques for identifying a display when a graphics processing unit (GPU) connected to the display via a display control bus is in a low power state. By providing a separate microcontroller with a parallel connection to the display control bus, the microcontroller may detect the presence of a display device even when the GPU is in the low power state. In response to detecting the display device, the microcontroller may notify a motherboard chipset (e.g., via an interrupt) prompting the motherboard chipset to initiate a sequence to bring the GPU out of the low power state.

摘要： In a diffusion tensor magnetic resonance imaging method for imaging a myocardial fiber structure, the diaphragm position of a subject is detected and a determination is made as to whether the diaphragm position of the subject falls into the acceptance region or not. If it does not, continue the diaphragm position of the examination subject is continued to be detected. If and when the diaphragm position is in the acceptance region, an echo planar imaging sequence with stimulated echo is executed with two electrocardiogram triggers, so as to acquire diffusion tensor image data of the myocardial fiber structure. The cardiac DTI image data thus can be obtained under free respiration of the subject, and the influence of respiratory movement is reduced and the scanning time is shortened.
