Abstract: Disclosed herein are a mode switching system and an exercise bike comprising the same that switches a non-freewheel mode and a freewheel mode automatically, ensuring improvement in user convenience. The exercise bike comprise a step motor, a first limit sensor sensing a first part of the face gear and outputting a first sensing signal, a second limit sensor sensing a second part of the face gear and outputting a second sensing signal, and a controller determining a current power transfer mode by using the first sensing signal and the second sensing signal, and rotating the step motor forward or reversely, based on the current power transfer mode, to switch the power transfer mode to the non-freewheel mode or the freewheel mode, in a case where a mode switching signal is input.

Abstract: A neural network accelerator includes a control circuit configured to control a learning operation for a neural network by performing a plurality of learning steps; an operation processor configured to perform the learning operation under the control of the control circuit; and an operation memory storing the embedding table that has a plurality of embedding entries and coupled to the operation processor, wherein the operation processor performs a first embedding operation using an embedding entry required for a current learning step, and performs a second embedding operation using an embedding entry that is required for a next learning step and is not affected by the current learning step.

Abstract: The present disclosure relates to a smart stroller and a method of controlling the same. The smart stroller includes a sensor part for sensing various information regarding a space in which a baby is seated and information regarding the surrounding environment in which the smart stroller is traveling. The sensed information is transmitted to a controller so as to be calculated as information for controlling operation of the smart stroller or information for informing to a user. This may enable the smart stroller to travel in a stable manner. This may also allow the user to check the state of the baby in real time and take necessary action.

Abstract: The present disclosure relates to a cart unit and a method of controlling the same. The cart unit includes a touch sensor that is mounted inside a handle to sense an object such as a user's hand approaching the handle, and a controller that calculates operation information according to information sensed by the touch sensor. The cart unit can be operated according to the calculated operation information. This can result in improving user convenience.

Abstract: A stroller can include a body having a pair of driving wheels mounted to left and right sides thereof; a motor configured to rotate the pair of driving wheels; a frame comprising a lower part connected to the body, the frame extending upwards from the lower part; a handle connected to the frame; a sensor unit including a force detection sensor configured to detect force applied to the handle, a touch sensor configured to detect whether the handle is being grasped, and a wheel sensor configured to detect rotation of the pair of driving wheels; and a controller configured to calibrate the force detection sensor based on data detected by the touch sensor and the wheel sensor.

Abstract: A cart can include a body having driving wheels mounted to left and right sides thereof; a motor configured to rotate the driving wheels; a frame comprising a lower part connected to the body, the frame extending upwards from the lower part; a handle connected to the frame; a sensor unit including a tilt sensor configured to detect a tilt of the body, and a touch sensor configured to detect whether the handle is grasped; and a controller configured to in response to determining that the handle is not grasped based on data detected by the touch sensor, determine whether the cart is located on a slope based on data detected by the tilt sensor, change a control parameter of the motor based on whether the cart is located on the slope and perform a braking operation in different ways based on whether the motor is rotating.
