Abstract: A device includes an interface and a processor. The interface receives information for a parameter indicative of a status of a battery. The processor calculates a remaining capacity of the battery, calculates a capacity ratio of the calculated remaining capacity to a capacity reference of the battery, compares the parameter with a parameter reference to generate a first comparison result, compares the capacity ratio with a ratio reference to generate a second comparison result, sets an amount according to the first and second comparison results, and changes the calculated remaining capacity by the amount.

Abstract: A detecting system includes a sense terminal and detecting circuitry coupled to the sense terminal. The sense terminal receives an indicative signal indicative of a supply current of a power source. The detecting circuitry calculates variation in the supply current based on the indicative signal, estimates power consumption of an application program residing on a computer-readable medium according to the variation, and detects whether an abnormal condition occurs by comparing the estimated power consumption with a reference.

Abstract: A multi-media system includes a display device and a controller. The display device receives a video signal indicating image content and displays the image content according to the video signal. The controller captures a user's information, identifies a user's sensory state according to captured user information, and generates a control signal according to the sensory state for controlling the display device. The user information includes image information. The sensory state includes eyeball movement.

Abstract: A credential provider component receives predetermined identity information (IDINF) from a portable device and controls an information database to provide a predetermined credential if the predetermined IDINF matches content in the information database. A log-on component allows the portable device to log on to a network device using the predetermined credential if the predetermined credential is valid.
