Abstract: A method for transmitting a message by ambient scattering. The method is implemented by a transmitting device in response to the transmitting device changing from a first state in which the transmitting device is deprived from illumination to a second state in which the transmitting device is illuminated by at least one light source. The method includes: obtaining an amount of electrical energy stored from light energy; comparing the amount of electrical energy stored with a given threshold, the threshold representing an electrical energy quantity sufficient to allow transmission of a message by ambient scattering; and in response to the threshold being overrun, transmitting a message called “information message”, representative of the threshold overrun, the transmission being implemented by using the stored electrical energy.

Abstract: A boot process for a computer comprising, in a client environment, a) generating, using a non-volatile data storage medium, a boot image request, b) passing the boot image request to a boot image repository, c) receiving, from the boot image repository, the requested boot image and d) booting the computer using the received boot image, characterised in that e) the boot image request is passed using an Internet Protocol and is sent to a predetermined location.

Abstract: A connection device for a computer comprising an optical connection part and an input/output controller, the optical connection part comprising a plurality of optical fibres embedded in a substrate, each fibre extending from a coupling end associated with an operative surface of the substrate and a connection end, the input/output controller comprising a plurality of light detectors and a plurality of light emitters, wherein the connection end of each optical fibre is associated with at least one light emitter and/or at least one light detector, characterised in that the input/output controller is operable to receive a message from a peripheral device located adjacent the operative surface, the message being transmitted via the optical connection part, the message comprising an identifier associated with the peripheral device.

Abstract: A software image transition aid is described for acting on a software image that is transferred from a source computer to a target computer, the aid comprising: a bootable storage media with stored thereon one or more operating systems arranged to load when the target computer is booted from the storage media and program code elements arranged to modify the cloned disk image under the control of the operating system or systems, so that when the target computer is rebooted from the transferred image the target computer will reach an operational state. The tool can be used in the following way. First the user transfers the complete operational software image from the target PC onto a source PC. Then, before being booted from the cloned image, the target computer is booted from the image transition aid. The image transition aid acts on the software image stored on the hard disk in the target computer.
