Abstract: A system for foreign object detection (FOD) in wireless power transfer is proposed. The system may include a balanced coil which is disposed between a transmitter coil and a receiver coil and which includes a Maxwell bridge circuit. The system may also include a temperature sensor configured to measure a temperature of the transmitter coil. The system may further include a processor configured to determine whether an FO is present between the transmitter coil and the receiver coil on the basis of voltage values detected at both ends of the bridge circuit. The FOD system can recognize the FO by finding a maximum resonant frequency at which a metal reacts using resonant frequency sweeping in a bridge circuit.

Abstract: This application relates to an apparatus and method for providing a wrap-around view based on three-dimensional (3D) distance information. The apparatus may include a camera module, a sensor module, and a controller. The camera module acquires image information in all directions, and the sensor module measures 3D spatial information in all directions. The controller is configured to generate 3D distance information by projecting the measured 3D spatial information onto a two-dimensional (2D) plane, to generate a 3D model in a 3D space by using the generated 3D distance information, and to generate a wrap-around view by mapping the acquired image information to the generated 3D model.

Abstract: Proposed is an apparatus, system, and method for conducting a company-customized work evaluation of employees based on work sincerity and work concentration to induce employees toward the ideal talent pursued by the company. The apparatus may receive an input of setting values for work sincerity and work concentration each including a plurality of evaluation items, setting values for weights for the respective evaluation items, and setting values for satisfaction/violation conditions from a manager terminal. Additionally, the apparatus may receive data on work sincerity and work concentration obtained by collecting and counting event information on satisfaction/violation for each evaluation item according to an employee's work from a plurality of employee terminals. Also, the apparatus may perform work evaluation on a plurality of employees via a work evaluation algorithm that uses the work sincerity and work concentration data and the weights as input values.
