摘要： The disclosed embodiments provide an apparatus that controls a current drawn from an adapter by a computer system. During operation, the apparatus senses the current drawn from the adapter using a first current sensor and a second current sensor, wherein a response time of the first current sensor is faster than a response time of the second current sensor. Then, when the current sensed using the first current sensor exceeds a predetermined high-current threshold, the apparatus limits the current drawn from the adapter to a first predetermined current limit. Additionally, when the current sensed using the second current sensor exceeds a predetermined thermal-limit current, the apparatus limits the current drawn from the adapter to the predetermined thermal-limit current.

摘要： A mobile terminal and a method of controlling an image display thereof are disclosed. A display module for a mobile terminal as disclosed herein may include a display for displaying an image that includes one or more objects, a user input interface to receive an input to change the image between a 2D display and a 3D display, and a controller configured to change the displayed image between the 2D display and the 3D display based on the received input. The controller may control the display to sequentially display one or more intermediate images in order to gradually change an extent in which at least one of the one or more objects is perceived to protrude or recede into the display during the change in the displayed image.
