摘要:
A print has a substrate and a plurality of memory tags coupled to the substrate. The print is an index print including a plurality of images and a memory tag is associated with each image for storage of data relating to that image. A print medium suitable for forming such a print has a substrate with a printable surface and a plurality of memory tags coupled thereto at locations spaced apart over the area of the substrate. Alternatively, memory tags may be applied to a printed print medium. Methods of providing printed images with associated stored data are described.
摘要:
A method of supplying information comprises providing a document having a memory tag. The document has a human-readable part presenting the information in human-readable form. The method further comprises storing change information identifying changes to the information on the memory tag.
摘要:
Access to a wireless data network to nodes located in a defined operational area is limited by transmitting a network signal within the defined operational area while transmitting a wave that can cause destructive interference with the network signal into a prohibited area adjacent to the defined operational area. The wave that can cause destructive interference is produced by phase and/or amplitude modulating the network signal. The modulation of the network signal includes sweeping the phase and/or amplitude.

A method of transferring high rate data between a first communications device (32) and a second communications device (1) is disclosed. The second communications device (1) has a first transceiver (4) for communication with the first communications device (32) at a first, low data rate over a long range, and a second transceiver (2) for communicating at a second, high data rate over a short range. The method comprises the steps of forming a coordinated short-range network (piconet) using the second communications device (1) and a plurality of other similar communications devices (11, 21), transferring a portion of said data to or from the first communications device (32) from or to each of said second communications device and said other communications devices using their first transceivers (2, 12, 22), and transferring said data portions between said other communications devices and the second communications device using their second transceivers (4, 14, 24).
摘要:
A distributed telemetry method is effected by coordinating the taking of readings of a parameter by mobile phone users, the parameter readings being then sent to a service system together with location information on the users. Collating the readings and location information enables a representation to be generated of the geographic variation of the measured parameter. Incentives can be offered to encourage cell phone users to participate in the telemetry method.
摘要:
Anti-counterfeit marking for a product, comprising: a tamper evident marker attached to or integrated with a product or packaging for a product and having a random mark; and an electronic memory element containing data about the random mark, the memory element being attached to or integrated with the product or packaging for the product in a tamper evident manner.
摘要:
A mobile telephone of an advertiser broadcasts an advertisement over a wireless short range piconet link to a mobile telephone of a consumer. The advertisement is broadcast with a predetermined set of classification tags. The consumer phone has a filter set to accept only certain advertisements. When an advertisement of interest is received by the consumer phone it requests further details automatically via the piconet link and the advertiser phone provides the further details automatically via the piconet link. The consumer phone replies to the advertisement by sending a reply message to a broker device that changes (i.e., modifies or augments the reply message text) and communicates the changed reply message to the advertiser.
摘要:
Methods are described for securing access to an electronic annotation provided on an object. The methods include the steps of providing the object with a plurality of memory tags, providing an electronic annotation on at least one of the memory tags, and defining a sequence in which the memory tags must be accessed in order to access the annotation. A corresponding object is also described.
摘要:
Location data about a mobile entity (20) is provided in encrypted form by a location server (79) to a recipient that is one of the mobile entity (20) or a service system (40) usable by the mobile entity. The location data (P) is encrypted such that it can only to be decrypted using a secret available to a decryption entity (80) that is not under the control of the recipient. This permits location data (P) to be provided in a confidential manner to service systems (40) and also protects billing relationships between participants. A mechanism is also described for limiting the accuracy of decrypted location data (L) made available to a service system (40).
摘要:
A wireless LAN comprises an access point with a data communicator for data communicated over different channels, each using a respective wireless technology, and at least one mobile communications device with a data communicator for data communicated over the channels and using the wireless technologies. A first of the channels uses a wireless technology operating at a first frequency bandwidth, and a second of the channels uses a different wireless technology operating at a second, non-overlapping frequency bandwidth. The wireless technology used for the downlink channel operates at a higher data rate than the wireless technology used for the uplink channel. The controller controls data communications over the downlink channel and the uplink channel to maximise the downlink data communication QoS.
