Abstract: A heart rhythm detection method and system by using radar sensor is capable of collecting an original signal using a radar sensor toward at least one subject, and converting the original signal to a two dimensional image information (i.e., spectrogram) using the concept of image vision. Then, the neural network automatically learns which heartbeat frequency should be focused on and which heartbeat frequency should be filtered out in the two dimensional image information through deep learning, so that the heartbeat frequencies can be extracted effectively.

Abstract: A fatigue data generation method, comprising: obtaining, by the camera device, a target image; obtaining, by a processor, a target feature data from the target image, and inputting the target feature data to a fatigue analysis model which stored in a storage unit, wherein the fatigue analysis model comprises a plurality of reference physiological signals, a plurality of reference feature data, a plurality of reference fatigue data and a plurality of correlation parameters; and generating a target fatigue data according to the target feature data, the plurality of reference feature data and the plurality of correlation parameters.

Abstract: A magnetoresistive random access memory (MRAM) device includes a first array region and a second array region on a substrate, a first magnetic tunneling junction (MTJ) on the first array region, a first top electrode on the first MTJ, a second MTJ on the second array region, and a second top electrode on the second MTJ. Preferably, the first top electrode and the second top electrode include different nitrogen to titanium (N/Ti) ratios.

Abstract: One embodiment provides a system that prevents duplicate entries in a non-blocking TLB that supports multiple page sizes and speculative execution. During operation, after a request for translation of a virtual address misses in the non-blocking TLB, the system receives a TLB fill. Next, the system determines a page size associated with the TLB fill, and uses this page size to determine a set of bits in the virtual address that identify the virtual page associated with the TLB fill. The system then compares this set of bits with the corresponding bits of other virtual addresses associated with pending translation requests. If the system detects that a second virtual address for another pending translation request is also satisfied by the TLB fill, the system invalidates the duplicate translation request associated with the second virtual address.
