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: A wearable illumination activity recording apparatus (1) includes a processing unit (11), a light sensing unit (12) and a motion sensing unit (13). The light sensing unit (12) is electrically connected to the processing unit (11) and outputs a light sensing signal (LS) to the processing unit (11). The motion sensing unit (13) is electrically connected to the processing unit (11) and outputs a motion sensing signal (MS) to the processing unit (11). The processing unit (11) determines whether the wearable illumination activity recording apparatus (1) is indoors or outdoors according to the light sensing signal (LS), and determines whether the wearable illumination activity recording apparatus (1) is in motion or not according to the motion sensing signal (MS). When the wearable illumination activity recording apparatus (1) is outdoors and in motion, the processing unit (11) records an illumination-receiving time.

Abstract: The present invention discloses a cover including a protecting layer, a decorative layer and a bottom layer. The decorative layer has a first surface, and a second surface on the opposite side of the first surface. The protecting layer integrally is formed on the first surface of the decorative layer by injection molding. The bottom layer integrally is formed on the second surface of the decorative layer by injection molding. The present invention also provides a method for manufacturing a cover. The present cover can tend give a various appearances whilst also having good performance.
