Abstract: An isolated bispecific antibody or antigen-binding portion thereof includes a first chain which specifically binds to human PD-1(hPD-1) and blocks the interaction between hPD-1 and PD-L1, and a second chain which specifically binds to human CD47 and inhibits its interaction with SIRP-alpha, where the first chain and the second chain are coupled in a knob-in-hole format through their respective CH3 domain.

Abstract: A button mechanism includes a button, a module, and a thin sheet spring. The thin sheet spring is in physical communication with the button and with the module. The thin sheet spring exerts a tension force on the button and the module to bias the button toward a normal position. In response to a force greater than the tension force being exerted on the button, a portion of the thin sheet stretches to enable the button to be placed in a contact position. In response to the force being removed from the button, the tension force causes the thin sheet to snap back to an original position and biases the button toward the normal position.

Abstract: A power device with multiple electrifying modes is disclosed. The power device includes a casing, a power wire, a receptacle unit, a connecting port unit, a circuit unit and a wireless charging module. The power wire is coupled to an alternating current power source. The receptacle unit and the connecting port unit are disposed on the casing. The circuit unit is coupled to the power wire, the receptacle unit and the connecting port unit. The circuit unit rectifies the alternating current power source to a direct current power source and provides the connecting port unit with the direct current power source. The circuit unit further provides the receptacle unit with the alternating current power source. The wireless charging module is coupled to the circuit unit. The circuit unit drives the wireless charging module to generate an electromagnetic field, so as to induct an electric potential for power supply.

Abstract: A flow meter comprises a housing with a tube, a floater inside the tube, and a permanent magnet embracing the housing. The volume of a fluid being passed through the tube defines the height of the floater position in the tube. The floater is equipped with a rotation coil and bulb connected thereto. Rotating the floater in the magnetic field of the permanent magnet under the influence of a fluid induces a voltage in the coil, and the bulb is turned on making reading volume values easier and more convenient.
