Abstract: Monoclonal antibodies against human Mac-1 are provided. These antibodies can bind to different states of Mac-1 so as to alter the biofunctions of Mac-1. These antibodies can modulate Th1/Th2 cytokine secretions by TLR-activated immune cells and can be used for the treatments of diseases related to acute and chronic inflammatory disorders, such as infectious diseases, and cancers.

Abstract: An electronic bead string includes a main bead, a plurality of secondary beads, a displacement sensor, a memory, and a processor. The main bead and the secondary beads are strung together to form a bead string. The displacement sensor is fixed in the main bead to output two-dimensional displacement signals, the memory stores the two-dimensional displacement signals, and the processor determines whether a rotation cycle of the electronic bead string is an approved rotation cycle according to the two-dimensional displacement signals.

Abstract: A fan rotation rate control device and the method thereof for controlling the rotation rate of the fan are provided. The fan outputs actual rotation rates and the control device includes a fan, a control unit, a processing unit and a thermal sensing unit. The thermal sensing unit is used to sense the temperature inside the heat generating device or the temperature of the heat source therein and outputs thermal sensing signals accordingly; the processing unit is coupled to the thermal sensing unit and receives the thermal sensing signal on which the determination of the preset rotation rate is based. Of which, the control unit which is coupled to the processing unit and the fan receives the preset and the actual rotation rates, while the control unit outputs modulation signals to the fan according to the difference between the actual and the preset rotation rates to achieve a precise control of the fan.
