摘要:
A display system and a method of displaying an image are hereby presented. The display system is arranged to display an image on a screen which has at least one useful screen area which is intended to be seen by a user and at least one non-useful screen area which the user cannot see. The display device comprises a bandwidth saver unit arranged to determine a location on the screen of a current pixel to be displayed. If the pixel is located in a non-useful screen area of the screen, then the fetching from a data memory of a pixel value is inhibited by the bandwidth saver unit with respect to this pixel, and a replacement, fixed pixel value is passed to a data processing unit for further processing.

The wireless subscriber device that is operable in a communique system for cellular communication networks operates with existing cellular communication networks to provide communique communication services to subscribers. The Communique can be unidirectional (broadcast) or bidirectional (interactive) in nature and the extent of the Communique can be network-wide broadcast or narrowcast, where cells and/or cell sectors are grouped to cover a predetermined geographic area or demographic population or subscriber interest group to transmit information to subscribers who populate the target audience for the narrowcast transmissions. The wireless subscriber devices used to communicate with the communique system for cellular communication networks are typically full function communication devices that include: WAP enabled cellular telephones, personal digital assistants, Palm Pilots, personal computers, and the like or special communique only communication devices that are specific to communique reception; or MP3 audio players (essentially a radio receiver or communique radio); or an MPEG4 video receiver (communique TV); or other such specialized communication device. The wireless subscriber devices can either be mobile wireless communication devices in the traditional mobile subscriber paradigm, or the fixed wireless communication devices in the more recent wireless product offerings. Furthermore, these communique communication services can be free services, subscription based services, or toll based services, while the data propagation can be based on push, pull and combinations of push/pull information distribution modes.

The present self-configuring emergency event alarm network uses a decentralized (ad hoc or mesh) architecture that does not have a centralized “master” node. In this ad hoc network, any node is capable of behaving as if it were the “master node” by autonomously reporting the alarm event directly to all other nodes in the ad hoc network independent of where the alarm event occurred. The network of alarm devices, therefore, can spread the alarm indication to the entirety of the area covered by the network of alarm devices and can also differentiate between a general alarm indication and the locus of the alarm event.

The communique system for cellular communication networks operates with existing cellular communication networks to provide communique communication services to subscribers. The communique can be unidirectional (broadcast) or bidirectional (interactive) in nature and the extent of the communique can be network-wide broadcast or narrowcast, where one or more cells and/or cell sectors are grouped to cover a predetermined geographic area or demographic population or subscriber interest group to transmit information to subscribers who populate the target audience for the narrowcast transmissions. The communique system for cellular communication networks can dynamically allocate the available bandwidth to thereby serve subscribers with more control channel(s) and/or control channel bandwidth and/or communication channels and/or communication channels of greater bandwidth as the need presents itself. The dynamic bandwidth allocation can simultaneously occur in multiple domains: time, code, frequency to thereby serve the needs of the subscribers to receive Communiques. The content of these transmissions can be multi-media in nature and comprising a combination of various forms of media: audio, video, graphics, text, data and the like. The subscriber terminal devices used to communicate with the communique system for cellular communication networks are typically full function communication devices that include: WAP enabled cellular telephones, personal digital assistants, Palm Pilots, personal computers, and the like or special communique only communication devices that are specific to communique reception; or MP3 audio players (essentially a radio receiver or communique radio); or an MPEG4 video receiver (communique TV); or other such specialized communication device.
摘要:
A controlled color light source including a lamp for projecting a beam of light, a power supply for energizing the lamp and a light conduit for sampling a portion of the light emitted from the lamp. A beam splitter is arranged to split the light from the conduit into two channels, and a pair of photo detectors, one for each channel are arranged to receive the light from the conduit via the beam splitter. A divider circuit has a pair of inputs and an output, the inputs being connected to the two photo detectors and an output circuit is connected to the output of the divider circuit for providing an output signal which is proportional to the color of light captured by the conduit.

摘要:
The present non-terrestrial feature transparency system spoofs the Air-to-Ground Network and the ground-based cellular communication network into thinking that the wireless subscriber devices have no special considerations associated with their operation, even though the wireless subscriber devices are located on an aircraft in flight. This architecture requires that the non-terrestrial feature transparency system on board the aircraft replicate the full functionality of a given wireless subscriber device, that has a certain predetermined feature set from a ground-based wireless service provider, at another wireless subscriber device located within the aircraft. This mirroring of wireless subscriber device attributes enables a localized cell for in-cabin communication yet retains the same wireless subscriber device attributes for the air-to-ground link. The Air-to-Ground Network transmits both the subscriber data (comprising voice and/or other data) as well as feature set data between the Aircraft in-Cabin Network and the ground-based cellular communication network to thereby enable the wireless subscriber devices that are located in the aircraft to receive consistent wireless communication services in both the terrestrial (ground-based) and non-terrestrial regions.
摘要:
An apparatus and method for providing a communique constituting program content concurrently delivered to a plurality of subscribers is described. Subscriber confirmation for each of a plurality of subscribers is stored. The subscribers whose wireless devices are active in a cell are identified. Data that identifies a plurality of subscribers is automatically generated. One or more cell are selected to provide communique to subscribers who are members of at least one community of subscribers and who are served by other cells of the cellular communication network. Data constituting said communique from a selected program source is routed, concurrently, to authorized wireless subscriber devices.
