Abstract: An electronic device includes a monitor stand, a hinge mechanism, and an operation element. The hinge mechanism includes a back plate, a speed reduction assembly, and a friction assembly. The back plate is fixed to the monitor stand. The speed reduction assembly includes an input plate and a speed reduction member. The speed reduction member is arranged on the input plate. The friction assembly is arranged between the back plate and the input plate. The operation element is connected to the speed reduction member. A rotation center of the operation element coincides with an axis of the back plate and the speed reduction member are coaxially arranged.

Abstract: A radar signal processing system with a self-interference cancelling function includes an analog front end (AFE) processor, an analog to digital converter (ADC), an adaptive interference canceller (AIC), and a digital to analog converter (DAC). The AFE processor receives an original input signal and generates an analog input signal. The ADC converts the analog input signal to a digital input signal. The AIC generates a digital interference signal digital interference signal by performing an adaptive interference cancellation process according to the digital input signal. The DAC converts the digital interference signal to an analog interference signal. Finally, the analog interference signal is fed back to the AFE and cancelled from the original input signal in the AFE processor while performing the front end process, reducing the interference of the static interference from the leaking of a close-by transmitter during the front end process.

Abstract: A magnetoresistive random access memory (MRAM) structure, including a substrate and multiple MRAM cells on the substrate, wherein the MRAM cells are arranged in a memory region adjacent to a logic region. An ultra low-k (ULK) layer covers the MRAM cells, wherein the surface portion of ultra low-k layer is doped with fluorine, and dents are formed on the surface of ultra low-k layer at the boundaries between the memory region and the logic region.

Abstract: A laser scanning projection apparatus includes an illumination unit, a projection surface, a scanning mirror, a projection window, an optical sensor, and a controlling unit. The projection window includes a transmissible part and a blocking part. A reflection-differential pattern is formed on the blocking part. When the laser beam reflected by the scanning mirror is projected on the transmissible part, the laser beam is transmitted through the transmissible part and projected on the projection surface. When the laser beam reflected by the scanning mirror is projected on the reflection-differential pattern, a reflective beam with different intensities is reflected by the reflection-differential pattern. The controlling unit calculates a phase difference between an actual projection position and a predetermined projection position of the laser beam according to the sensing signal, and compensating a subsequent image frame according to the phase difference.

Abstract: A microprobe array structure with self-stabilization capability and a method for manufacturing the same are proposed. The microprobe array structure is used to sense various biopotential signals, and is characterized in that the etching parameters are controlled during etching to manufacture a microprobe structure with a reduced bottom cross section so that the microprobe can be firmly stabilized in the skin tissue. Moreover, a conducting layer is formed on the microprobe to sense signals. A design of electric isolation between microprobes is also proposed. The microprobe array can therefore be used for the measurement of various biopotential signals, and can also be used as a stimulus.
