Abstract: A physical object comprises one or more memory circuits adapted to be read wirelessly by a reader device attached to or incorporated within the physical object. Data in the memory circuit is protected from access by an unauthorised reader. Data in the memory circuit is also adapted to identify an authorised bearer of the physical object. Moreover, data in the memory circuit is adapted to allow access to a specified asset or assets by the authorised bearer.

Abstract: A data storage device includes a temperature sensor. The temperature sensor outputs a temperature signal corresponding to a detected temperature. An identification unit connected to the temperature sensor generates and outputs an identification signal based on the temperature signal. A plurality of such data storage devices can therefore be identified by their relative position to an interrogator which outputs heat.

Abstract: A method provides travel directions to facilitate travel to destination to a user having a mobile networkable device. Destination data is read with a reader device from a memory tag, the memory tag being a passive device comprising an electronic memory. The memory tag is attached to an article relating to said destination data. Destination data is thereby provided to the mobile networkable device. Travel directions are then derived from said destination data and presented to the user on the mobile networkable device.

Abstract: This invention provides a processor 900 for writing data contained in payload data 1006 of a data packet 1000 to memory, especially for use as the central processing unit of a memory tag 1200. The processor 900 does not include a write buffer. The processor 900 comprises a first register 910 adapted to latch first data corresponding to a segment of the payload data; and a second register 224 adapted to receive second data from the payload data 1006 to enable the validity of the data latched into the first register 910 to be established before data is written to memory. A memory device, a method for writing data contained in payload data 1006, a data packet 1000, a method of writing data into a non-volatile memory and a memory tag are also provided.

Abstract: This invention provides a processor 200, especially for use as the central processing unit of a memory tag 1200. The processor 200 has a minimal footprint in Silicon or other suitable material. It also is driven by the data that it receives. The processor includes a plurality 206, 212, 214, 224 of registers configured to receive in parallel data that are input to the processor, and to process in parallel the received data, and a micro sequencer and instruction decoder module 202 adapted to select two or more of the plurality of registers to receive the data that are input to the processor, and to control the processing of the received data by the end or more selected registers.

Abstract: A media product comprising an electronic tag, the tag comprising a memory, wherein the memory has data stored thereon representing preview material associated with the content of the product. A suitable tag and device for querying a memory of the tag are also described.

Abstract: A position sensor is disclosed with detector elements 11 coupled to a set of output lines 20 according to a connection pattern 30. An object 2 triggers a window subset of the detector elements 11, causing a logic output on the set of output lines 20. Some output lines 20a are coupled to more that one detector element 11. However, the connection pattern 30 is arranged such that for any window subset of the detector elements falling in a variable length range, a unique logic output is provided on the set of output lines 20 to identify the position of the object. A sensing method and search process for determining the connection pattern are also disclosed.

Abstract: A memory tag comprising a resonant circuit part and a non-volatile memory, the resonant circuit part being operable, in response to a reader signal received from a reader, to provide power to the memory, the tag being operable to read the memory and transmit data stored in the memory in response to the signal from the reader, wherein the data is stored in the memory in a plurality of data units, each data unit having an associated sequence number, the tag being operable to store the sequence number of the data unit to be transmitted in a register in the non-volatile memory, and when power is supplied to the memory, the data units are transmitted in sequence, the first data unit to be transmitted depending on the stored sequence number.
