There is provided a method and a system for documenting a transfer of authority of control for a container from a first entity of a transportation chain to a second entity of the transportation chain. The first entity transfers an electronic container control certificate to an electronic seal of the respective container, which electronic container control certificate comprises a cryptographic key associated to the second entity, and which container control certificate is digitally signed by the first entity. The container control certificate is stored in a log of the electronic seal.

Scheme and apparatus (10) for distinguishing services offered by a service-providing device in adjacency of the apparatus (10) from services offered by a service-providing device not being in the apparatus' adjacency. All devices—including the apparatus—are part of a wireless local network. The apparatus (10) maintains a record with information about services and associated identifiers as well as a list of identifiers about the service-providing devices. The associated identifiers and the list of identifiers are compared to determine an associated service as being in adjacency of the apparatus if it is rendered by a service-providing device being listed in the list of identifiers. An associated service is determined as not being in adjacency of the apparatus if it is rendered by a service-providing device not being listed in the list of identifiers. The apparatus (10) comprises a network interface (25) for wireless communication with the service-providing devices, and a service discovery module (11) which maintains the record with information services and associated identifiers.

Displaying information related to a physical parameter of an individual. An individual being any living form including a human being and an animal. An example system includes a sensor for measuring a physical parameter of an individual, a database remote from the sensor for storing data assigned to an individual, and a display remote from the database for displaying the information which information is based on a value measured and provided by the sensor for this individual and based on the data assigned to this individual and provided by the database.

Methods, system and apparatus are provided for advertising service offerings in a communication system. An example embodiment comprises at least one device. A first device broadcasts a message of a first type, chooses a value for a time limit and listens for a message sent by a second device. If no message has been received before time limit, elapse, it again broadcasts a message of a first type. Otherwise, the message received from said second device is analyzed and if said message includes valid information about said first device chooses a value for the time limit. However, if said message received does not include valid service description about said first device, a message of a second type is broadcast. This reduces useless broadcast of a complete service list. Broadcast may be initiated more often and, service discovery for new devices coming into proximity takes less time.

A system is provided for transmitting generally static media. The system (10) comprising an electronic device (12) and a digital audio transmitter (14). The electronic device (12) has a CPU (16), a storage medium (18), a display (20), a user interface (22), and a digital audio broadcast receiver (26). The digital audio transmitter (14) has a specialized broadcast server (30). The digital audio broadcast receiver (26) receives and decodes the digital audio signal transmitted by the digital audio transmitter (14).

Methods for providing a receiver subsystem with access via a clearing house subsystem to a content item broadcast from a content provider subsystem. A method includes generating the request for access in the receiver subsystem, and employs a content key, a blocking nonce, a public key of a public-private key pair, a public key encrypted content key, and a double encrypted content key. The method may also include, in the receiver subsystem, encrypting the request for access based on the private key of the public-private key pair. Provides apparatus for providing access to a broadcast content item. A receiver subsystem is arranged to generate the request for access. In an example embodiment the receiver subsystem is arranged to encrypt the request for access based on the private key of the public-private key pair. Provides a receiver subsystem, a content provider subsystem, and a clearing house subsystem.
摘要:
A device and method for advertising service offerings in a communications network. A service offering includes information about the device making the advertisement, including what functions the device may serve. The advertisement also includes information about other devices in the network, when that information is available. Each device in the network determines a time value, at the end of which the device will send an advertisement. Each device listens for advertisements from other devices up to the time previously determined. If a device receives an advertisement that contains information about itself then the device will determine a new time value, at the end of which the device will send an advertisement. If a device receives an advertisement that does not contain information about itself then the device will send its own advertisement.
