The object of the present invention is to realize a virtual image distance changing device and so on capable of presenting a target, an object to be viewed by a user, at a virtual image distance that corresponds to an actual depth of the target. The virtual image distance changing device includes a display panel, optics, depth information acquisition means, and distance changing means. The display panel displays an image that corresponds to image information. The optics guides the image displayed on the display panel to user's eyes and causes the user to view a virtual image that corresponds to the image. The depth information acquisition means acquires depth information that represents the depth of the target to be viewed, the object displayed on the display panel to be viewed by the user. The distance changing means changes a virtual image distance that represents a distance at which the virtual image is viewed by the user corresponding to the depth information.

Methods and apparatus are disclosed to determine a power state of a device. An example apparatus includes a chart generator to determine respective counts for a plurality of measurements during a calibration period, the measurements indicative of an amount of power drawn by the device, a calculator to determine a first threshold and a second threshold based on at least one of the counts, the first threshold determined using most frequently logged measurement values, the most frequently logged measurement values based on counts performed after expiration of the calibration period, and a comparator to compare a measurement to the first threshold and to the second threshold.
