Abstract: A file creation method comprising: creating file content at a particular location and time using a portable device; and obtaining data from wireless communication devices detectable by the portable device at the particular location and time thereby to obtain a set of data. The set of data identifies or enables identification of the wireless communication devices. The method further comprises associating the set of data and time with the file content to enable subsequent analysis to determine the particular location using a time-dependent database.

Abstract: A method of determining the location of a portable device comprises obtaining identities of wireless communication devices detectable by the portable device at a particular location which is to be determined, thereby to obtain a set of identities. The set of identities is compared with the content of a database, which database stores a plurality of findings, to select one or more findings; each finding comprising a reference location and a set of identities of wireless communication devices sighted at that location. The location of the portable device is found based on processing the selected findings.

Abstract: A method of automatically configuring a device. The method comprises: obtaining an image of a scene comprising a machine-readable code containing configuration information for the device; processing the image to extract the configuration information; and using the configuration information to configure the device. The step of obtaining the image comprises at least one of: capturing the image using a camera; or receiving the image captured by a camera. The configuration information comprises date or time information.

Abstract: Apparatus for displaying an image comprises a liquid crystal display 12, a lenticular lens array 14 for directing different portions of the image in different directions and mirrors 16 for reflecting at least some of the directed image, to produce an effective image 18 larger than the original image. The apparatus can be a mobile phone 10 or a visual display unit.

Abstract: Buyer, vendor and third party computer systems are disclosed together with a related method for enabling a prospective Buyer to browse a Vendor's website to purchase goods or services. According to one aspect of the present invention, the Buyer's computer system automatically extracts purchase information from the Vendor's website from which the Vendor can identify the Buyer's purchase. According to a further aspect of the present invention, the Buyer's computer system transmits, under control of the Buyer, confirmation to the Vendor that a third party has been instructed to pay the Vendor for the Buyer's purchase. In a yet further aspect of the present invention, a third party's computer system transmits to the Vendor confirmation of receipt of an instruction from a Buyer to pay a Vendor for goods or services.

Abstract: Image recording apparatus such as a camera (2) stores data (8) representing still or moving image data on a data carrier (12). A rotation sensor (14) measures the angle of orientation of the camera The stored data is based both on the image data and the output angle data to allow the captured image to be rotated for display to have the true horizontal displayed as horizontal.

Abstract: A method of modelling a function call in a state machine comprises generating a model of a state machine which calls a function call. A function call mf1 is modelled in a second state machine which is independent of the first state machine. When the first state machine calls the function call, for example using a leafstate “calling”, the function call state machine mf1 is temporarily implanted over the “calling” state. Static recursion or infinite compile time recursion is avoided since the implantation is made only at the time of calling the function call, rather than at compiled time. After entering the state machine mf1, return is made to the first state machine after transition to a terminator state, which fires an event called $return (where $ indicates scoping back one level, and return indicates an event which fires the transition to state “after”). This can be described as a synchronous function call. An asynchronous function call is shown in FIG. 17.
