Abstract: An electric bicycle theft prevention system for preventing theft of an electric bicycle according to an embodiment of the present disclosure includes a motor unit, a sensor unit, a controller, and an alarm unit. The motor unit is a permanent magnet synchronous motor (PMSM), and is configured to rotate wheels of the electric bicycle by receiving power from an electric storage unit. The sensor unit is configured to detect a position of a rotation shaft or a rotor of the motor unit. The controller is configured to control the motor unit and the sensor unit. The alarm unit is configured to generate an alarm by an electrical signal of the control unit. In addition, when a theft prevention function is activated in an unused state of the electric bicycle, the controller monitors a sensor value of the sensor unit to detect a movement of the electric bicycle.

Abstract: According to an embodiment of the present invention, An electric bicycle theft detection system includes: a pedal; a pedal rotation speed detector configured to measure a rotation speed of the pedal; a driving wheel configured to rotate by receiving power; a motor configured to rotate the driving wheel; a driving wheel rotation speed detector configured to measure the rotation speed of the driving wheel; a control device configured to detect theft based on the rotation speed of the pedal, a torque of the motor, and the rotation speed of the driving wheel; and a user interface device configured to generate a warning signal when the control device detects the theft.

Abstract: An electric module for a bicycle according to an example embodiment of the present disclosure is equipped on the bicycle including a pedal configured to generate rotational energy and a driving wheel configured to rotate by receiving power, and the electric module includes a pedal rotation speed detector configured to measure a rotation speed of the pedal, a motor configured to rotate the driving wheel, a driving wheel rotation speed detector configured to measure a rotation speed of the driving wheel, a control device configured to determine whether a tire is abnormal based on the rotation speed of the pedal, a torque of the motor, and the rotation speed of the driving wheel, and a user interface device configured to display condition information of the tire provided by the control device.

Abstract: A transgenic cloned piglet expressing human proinsulin and a method of preparing the same, and more particularly, to a recombinant vector for human proinsulin expression, a genetically modified cell line into which the recombinant vector is introduced, a transgenic cloned piglet expressing human proinsulin, and a method of producing the same.

Abstract: The present invention relates to a transgenic pig in which an immune rejection response is suppressed during xenotransplantation, wherein a gene coding for heme oxygenase-1 (HO-1) and a gene coding for tumor necrosis factor receptor 1-Fc (TNFR1-Fc) are simultaneously expressed and a gene coding for ?-1,3-galactosyltransferase (GGTA1) is knocked out; and a method for producing the same.
