Tile-based camera mode switching
A method is executed at a camera operating in a night mode in which an IR filter is not interposed between a lens assembly and sensor arrays of the camera. In the night mode, the camera receives ambient light that is not filtered by the IR filter. For each image tile, the camera determines whether the ambient light received at the tile is due to an IR light source or a light source other than an IR light source and generates a respective mode change signal accordingly. A mode change parameter is then determined as a function of a total number of the mode change signals for image tiles of the camera. Based on the mode change parameter, the camera determines whether to continue the operation of the camera in the night mode or switch the operation of the camera from the night mode to a day mode. |

Mitigating automated attacks in a computer network environment
This disclosure describes a technique to slow down or block creation of automated attack scripts by configuring a detector to discriminate whether particular attack-like activity is a true attack, or simply a hacker “testing” his or her automated attack script, and then permitting any such test script to continue working (attacking) the site, albeit on a limited basis. In this manner, the hacker receives an indication that his or her automated attack script is already working. Thereafter, when the detector later detects a launch of an actual attack based on or otherwise associated with the automated attack script (previously under test), the attack fails either because the script was not a working script in the first instance, or because information learned about the script is used to adjust the site as necessary to then prepare adequately for a true attack. |

Display device having a reflecting area
A display device is provided. The display device includes a changeable reflective structure having a first changeable electrode, a changeable reflecting layer and a second changeable electrode, which are sequentially stacked on an upper substrate opposite a lower substrate. In the display device, the reflectance of the changeable reflecting layer may be adjusted by controlling a voltage applied to the first changeable electrode and the second changeable electrode according to a state of a light-emitting structure which is disposed on an emitting area of the lower substrate. Thus, in the display device, a decrease of the color sense by the reflection of external light in a display state may be prevented, and the reflective area may have sufficient reflectance for serving as a mirror in a non-display state. |
