Abstract: Disclosed herein is a torque detector. The torque includes a synchronous detector, a bridge circuit and a signal converter. The synchronous detector detects an AC voltage signal having a preset DC voltage level and a certain frequency, and generates a detection output signal. In the bridge circuit, a torque detection coil whose inductance varies with rotation of a steering wheel and a temperature compensation coil whose inductance varies with temperature variation are connected in series to each other. The detection output signal and the DC voltage are applied to both ends of the two connected coils, respectively. The bridge circuit allows a first detection voltage to be induced at a connecting point between the two coils by variation of the inductance of the two coils. The signal converter generates a torque detection signal having an amplitude corresponding to a difference between peak values of a preset reference voltage and the first detection voltage.

Abstract: A number label embedded with an antenna tag for measuring a runner's time record using wireless identification (ID) at a recording race such as a marathon or walking race, and a runner's recording measurement method and system using the same are provided. There was a number label having a bar code in the past. However, if a bar code is screened by the body of a person who is attached with a bar code number label or the other user's body when a bar code reader or bar code scanner recognizes the bar code number label, the bar code may not be decoded. To solve this defect of the bar code wireless identification, there has been a technology of measuring and managing runners' IDs and time records, in which an antenna tag having a predetermined ID is attached to runners' bodies, respectively, for example, a radio frequency (RF) chip is attached to each runner's body, and then the antenna tag communicates with an antenna array to thus perform a wireless identification.
