An automatic focusing system comprises at least one micromirror array lens, an image sensor, and a signal processor. The micromirror array lens images an object and focuses the image on the image sensor. The image sensor receives the light and converts the photo energy of the light to electrical energy in the form of an electrical signal. The image sensor sends the electrical signal, which carries image data concerning the object, to the signal processor. The signal processor receives the electrical signal, compares the image quality of the image data to its focus criteria, and generates a control signal, which it sends to the micromirror array lens to adjust the focal length of the micromirror array lens. This iterative process is continued until the quality of the image data meets the focus criteria, and the process is completed within the afterimage speed of the human eye.

For traffic offload via a local network, a MME may obtain from a HSS, subscription data including SIPTO related permissions defined on APN basis that indicate SIPTO prohibited, indicate SIPTO allowed excluding SIPTO via Local Network (SIPTO@LN), and/or indicate SIPTO allowed including SIPTO@LN. Then, the MME may obtain information about one or more local Gateways (GWs) capable of offloading selected traffic, such information indicating which of the one or more local GWs provides access to which Packet Data Networks (PDNs), with each PDN being identified by its associated APN. Finally, the MME may process PDN connections and/or PDN disconnections in order to support offloading of the selected traffic. The counterpart UE includes the appropriate means of hardware and/or software that is configured to support and perform SIPTO@LN.

Television broadcasting systems of this invention comprise an imaging system, and transmission system, and a displaying system. The imaging system captures two-dimensional images of an object at different focal plane, and generates an all-in-focused image and depth profile. A data signal carrying the image data is generated and transmitted over a broadcasting system compatible with commercial two-dimensional television broadcasting, cable, and/or alternative systems. The depth profile is transmitted by using vacant space in video/audio signal within the allocated channel bandwidth. The data signal is received by the displaying system and the extracts the all-in-focused image and depth information from the data signal. The object is restored from all-in-focused image and depth profile and displayed on the displaying system as a three-dimensional spatial image. Viewers having conventional two-dimensional display device can watch enhanced two-dimensional images.
