Abstract: A device for low-power bidirectional wireless data telemetry includes: a coil unit configured to perform forward telemetry and back telemetry; a full-wave rectifier unit configured to convert an AC voltage into a DC voltage; a current modulator configured to change a magnetic field by altering a path of the AC current generated, when the back telemetry is performed; an energy storage configured to generate a reuse power using the AC current; and a LDO unit configured to generate a source voltage using the power output from the full-wave rectifier unit and the reuse power generated by the energy storage. Accordingly, since the back telemetry and the forward telemetry may be performed simultaneously and the wasted current is reused, the power required for back telemetry may be reduced.

Abstract: Disclosed is a method for performing an adversarial attack by a computing device including one or more processors, which may include: generating a first conversion image by inputting an original image into a first neural network model; generating first object detection result data by inputting the first conversion image into a second neural network model; generating first noise based on a first loss value between the first object detection result data and a prestored ground-truth; generating a first adversarial image based on the first noise and the first conversion image; generating second noise based on a second loss value between the first adversarial image and the first conversion image; and generating a second adversarial image based on the second noise and the original image.
