Abstract: A sense amplifier circuit includes a sense amplifier, a switch and a temperature compensation circuit. The temperature compensation circuit provides a control signal having a positive temperature coefficient, based on which the switch provides reference impedance for temperature compensation. The sense amplifier includes a first input end coupled to a target bit and a second input end coupled to the switch. The sense amplifier outputs a sense amplifier signal based on the reference impedance and the impedance of the target bit.

Abstract: A calibration apparatus includes a processor, an alignment device, and an arm. The alignment device captures images in a three-dimensional space, and a tool is arranged on a flange of the arm. The processor records a first matrix of transformation between an end-effector coordinate-system and a robot coordinate-system, and performs a tool calibration procedure according to the images captured by the alignment device for obtaining a second matrix of transformation between a tool coordinate-system and the end-effector coordinate-system. The processor calculates relative position of a tool center point of the tool in the robot coordinate-system based on the first and second matrixes, and controls the TCP to move in the three-dimensional space for performing a positioning procedure so as to regard points in an alignment device coordinate-system as points of the TCP, and calculates the relative positions of points in the alignment device coordinate-system and in the robot coordinate-system.

Abstract: A bottom-pinned spin-orbit torque magnetic random access memory (SOT-MRAM) is provided in the present invention, including a substrate, a bottom electrode layer on the substrate, a magnetic tunnel junction (MTJ) on the bottom electrode layer, a spin-orbit torque (SOT) layer on the MTJ, a capping layer on the SOT layer, and an injection layer on the capping layer, wherein the injection layer is divided into individual first part and second part, and the first part and the second part are connected respectively with two ends of the capping layer.

Abstract: A climate management system for a power supply system including a plurality of cabinets is disclosed. The climate management system comprises a plurality of climate control units connected and in communication with each other, wherein each climate control unit is disposed in a corresponding cabinet to monitor, manage and control the corresponding cabinet, wherein one of the climate control units is defined as a master climate control unit and the other of the climate control units are defined as slave climate control units; and a control system unit connected and in communication with the master climate control unit. The master climate control unit is configured to collect, process and integrate the information transmitted from the slave climate control units and report the collected, processed and integrated information to the control system unit.

Abstract: A seedlings transplanting machine, which includes a machine base having a platform at the top and a rail transversely disposed above platform and reciprocated longitudinally, a sliding frame placed on the platform and reciprocated along the rail to carry a seedling tray, a first transmission mechanism controlled to move the sliding frame along the rail, a second transmission mechanism controlled to reciprocate the rail longitudinally, a seedling drop unit controlled to draw seedlings away from the tray and then to plant the seedlings in the soil.
