Abstract: An intelligent digital television receiver for receiving a video signal, an audio signal and a digital data transmitted in a digital broadcast, and for executing an application based on the received digital data by itself or in connection with the received video and/or audio signal. The receiver has a controller for controlling executions of applications by generating events according to event start information bearing time information contained in a digital data stream as an object which comprises an element of the application and another controller for controlling executions of the application.

Abstract: A method and system for verifying the contents of a cargo container includes acquiring at least one image of the cargo container and of the contents of the cargo container, the image being one of a backscatter X-ray image of the cargo container, and a transmission X-ray image of the cargo container. The image is stored with a manifest associated with the cargo container. The manifest is sent to another location, and, at the other location, selectively, a second image of the contents of the cargo container is acquired; and compared with the image stored with the manifest associated with the cargo container.

Abstract: A wheel balance weight including a plurality of weight bodies of at least one kind and an adhesive double-coated tape. Each of the plurality of weight bodies is made from a metal other than lead and the side surfaces of adjacent weight body are tapered. The balance weight may include one or more weight bodies each having a predetermined weight of W and W/n. The balance weight may include one or more weight bodies each having a predetermined weight of W and a summation of W/n and W. A method of manufacturing a balance weight includes: producing a bar material having tapered surfaces at opposite sides, cutting the bar material into a plurality of weight bodies, and attaching the plurality of weight bodies to an adhesive double-coated tape.

Abstract: A method and mobile communication system for managing authentication keys, the system having at least one authentication center, base stations and mobile stations to which subscriber identity modules may be coupled and which communicate with the base stations. The authentication keys are managed by: generating authentication keys and identifiers corresponding thereto, each of which identifiers is independent of a mobile subscriber identity, which allow authentication keys corresponding to the identifiers to be found in the authentication center, storing the authentication keys in the authentication center so that the authentication keys may be found in the authentication center on the basis of the identifiers, and storing the authentication keys and the identifiers corresponding to the authentication keys to the subscriber identity modules.
