Abstract: A method of driving an electronic device includes displaying a plurality of fingerprint recognition icons on a display device configured to perform fingerprint recognition, and releasing a lock state of the display device through a fingerprint authentication process upon determining at least one first fingerprint recognition icon among the plurality of fingerprint recognition icons is touched. The plurality of fingerprint recognition icons include at least one first fingerprint recognition icon configured to support the fingerprint recognition and at least one second fingerprint recognition icon configured to not support the fingerprint recognition.

Abstract: Controlling a speed limit includes determining a virtual vehicle speed as being a lower one of a vehicle speed and a target limit speed, determining a virtual APS value as being a larger one of a first APS value and a second APS value, transitioning to a second mode at a point in time at which an actual APS value and the second APS value become different, when it is expected to transition to the second mode, among a first mode for sustaining a SOC of a battery at the target limit speed and the second mode for depleting the SOC, and determining a transmission gear position by applying the determined virtual vehicle speed and the determined virtual APS value to one of a first shifting pattern and a second shifting pattern.

Abstract: A coated cutting tool having excellent wear resistance and controlled brittleness is provided. An embodiment of the present disclosure provides a coated cutting tool including: a substrate; and a cutting layer disposed on the substrate, wherein: the cutting layer includes a brittleness suppressing layer and a wear-resistant layer disposed on the brittleness suppressing layer; the substrate includes a hard alloy body such as cemented carbide, cermet, ceramic, cubic boron nitride-based materials, or high-speed steel; the brittleness suppressing layer includes a first layer and a second layer disposed on the first layer; the first layer and the second layer each independently includes any one of (AlbTi1-b)X (where 0.6<b<0.8, and X is at least one selected from N, C, CN, NO, CO, and CNO) and (TicAl1-c)X (where 0.4<c?0.5, and X is at least one selected from N, C, CN, NO, CO, and CNO); and the first layer and the second layer include materials different from each other.

Abstract: A brake lamp control method of a vehicle is provided. The method includes determining whether a deceleration of the vehicle based on regenerative brake through the electric motor is present in a hysteresis period between an off threshold as a reference for turning off a brake lamp and an on threshold as a reference for turning on the brake lamp. When the deceleration of the vehicle is present in the hysteresis period, the method includes determining a state of the brake lamp before the deceleration of the vehicle enters the hysteresis period. In response to determining that the brake lamp is turned on or off for a reason except for the regenerative brake before the deceleration of the vehicle enters the hysteresis period, a request for turning on the brake lamp is set or reset based on the regenerative brake in response to the determined state of the brake lamp.

Abstract: An apparatus and method control regenerative braking torque of an electric vehicle on which an anti-lock brake system (ABS) is mounted. The apparatus and method can compensate the regenerative braking torque of the driving motor based on the behavior model of the electric vehicle, such that the ABS is prevented from entering an operating range to the maximum limit to maximize the energy recovery rate through regenerative braking. The apparatus includes a disturbance extractor that extracts a disturbance in a specific frequency band from a difference between a behavior model and an actual behavior of the electric vehicle. The apparatus includes a torque compensator that compensates for the regenerative braking torque based on the disturbance extracted by the disturbance extractor.
