摘要： An identification tag (1) has at least one molecule of a first type (3) and at least one molecule of a second type (4). The molecules (3, 4) are capable of energy transfer according to Förster Resonance Energy Transfer, with one of the types being donor molecules and the other type being acceptor molecules. The tag (1) has a substrate (5) which has a plurality of locations (6) at which molecules of the second type (4) may be located. The light intensity emitted by the acceptor molecule(s) (4) as the molecule of the first type (3) is moved across the locations (6) varies in dependence on whether a molecule of the second type (4) is or is not located in the locations (6).

摘要： The present invention provides a device at least comprising a laminated heterostructure (10) and a data modulating and energy harvesting control unit (6) electrically connected to the laminated heterostructure. The laminated heterostructure (10) comprises a graphene layer (2) and a dielectric-metal compound layer (4). The dielectric-metal compound layer (4) may, for example, comprise doped silicon or doped aluminium. The control unit (6) is configured to alter the relative proportions in which the laminated heterostructure (10) can reflect and absorb incident radiation by altering the optoelectronic properties of the laminated heterostructure, and to select whether the laminated heterostructure (10) transmits data by optical modulation of incident radiation, harvests energy from incident radiation, reflects incident radiation, or a combination of all three. Thus, the invention also provides a method of operating a device comprising a laminated heterostructure (10) of a graphene layer (2) and a dielectric-metal compound layer (4). The control unit (6) may set the relative proportions in which the laminated heterostructure (10) can reflect and absorb incident radiation to be different at different wavelengths, and to absorb or reflect substantially all of the incident radiation in a particular waveband. Furthermore, the invention provides an apparatus comprising a plurality of devices, each comprising such a laminated heterostructure (10), which can be arranged in a cellular pattern on a surface (12), such as by inkjet printing or by being integrated into a flexible membrane. The surface may, for example, be a wall of a building or an outer surface of a domestic appliance or of an electronic device. Thus the apparatus is able to provide the surface of whatever object it is applied to with a "smart" coating, the optoelectronic properties of which can be altered as desired to give the surface a variety of different functions.

摘要： There is an implantable medical device (20) comprising an acousto-optic transducer (200), a photodetector (300), and an optical communication channel (400) connecting an output of the acousto-optic transducer (200) to an input of the photodetector (300). The components of the implantable medical device (20) can be made sufficiently small that they can be implanted into a living subject with ease and require no external power supply. Since the acousto-optic transducer (200) can receive acoustic signals, which are transmissible through bone, the device (20) can be implanted into a living bone and can be communicated with transdermally. There is also a wireless communication system comprising such an implantable medical device (20) and an electro-acoustic transducer (30a, 30b, ... 30n) able to transmit information to the implantable medical device (20) by transdermal transmission of an acoustic signal. Such a system is particularly suited to the repair of spinal injuries. A method of transdermal wireless communication is also provided, comprising transmitting an acoustic signal from outside a human or animal subject, receiving the acoustic signal within the human or animal subject, and converting the acoustic signal into an optical signal, as well as a method of in vivo communication, comprising transmitting an acoustic signal within a human or animal subject, and converting the acoustic signal into an optical signal. Preferably, the acoustic signal is converted into an optical signal using Förster resonance energy transfer (FRET) from a donor molecule to a receptor molecule within the acousto-optic transducer (200).

摘要： The present invention provides a communications transmitter (8), which is suitable for wireless communication. The transmitter (8) at least comprises a transmitting electrode (10), a modulator for modulating an electrical charge to apply to the transmitting electrode (10) with an information-bearing signal, a charger for applying the modulated charge to the transmitting electrode, a source (18) of ionising radiation for at least partially ionising a body of ionisable gas (12, 12') in contact with the transmitting electrode (10), and a gas pressure pump for imparting a velocity, v, to the body of gas (12, 12') to direct it away from the transmitting electrode (10) more rapidly than a natural diffusion velocity of the body of gas. This transmitter (8) can be incorporated into a wireless communications apparatus, along with a receiving electrode (16), a channel disposed between the transmitting electrode (10) and the receiving electrode (16) for transporting the body of ionisable gas (12, 12') from the transmitting electrode to the receiving electrode, an electrical charge-measuring device for measuring an electrical charge on the receiving electrode (16), and a demodulator for demodulating the electrical charge measured on the receiving electrode (16), in order to recover the information-bearing signal. The present invention also provides a corresponding method of wireless communication using an at least partially ionised body of gas (12) ( i.e. a plasma) as the communication medium, which is substantially immune to external radio-frequency sources of electromagnetic radiation, thereby rendering it invulnerable to jamming or interference. Moreover, since the plasma is electrically charged, it can also be used to transmit electrical power along with information, in simultaneous wireless information and power transfer (SWIPT).

摘要： An arrangement (1) in a washing machine (99) for determining optimal wash scheme for a load (90) received into a drum (3) of the washing machine (99) is presented. The arrangement (1) includes a micromachine (10), one or more sensors (20), and a microcontroller (30). The micromachine (10) has a hearth (12) for receiving a part (91) of the load (90) from the drum (3) and is configured to wash the part (91) prior to washing of the load (90) present in the drum (3). The sensors (20) are positioned around the hearth (12) and are configured to determine one or more parameters relating to characteristics of water used in the washing machine (99), characteristics of detergent solution formed in the washing machine (99), and/or characteristics of the part (91) of the load (90). The microcontroller (30) receives, from the sensors (20), one or more signals indicative of the parameters so determined by the sensors (20), and subsequently determines a wash scheme for the load (90) based on the parameters so determined by the sensors (20).

摘要： Wireless information and power is transferred simultaneously from a first device (304) as the first device (304) moves. A set (100) of first coils (102) for fitting to a first device (304) interacts with a set (200) of second coils (202). At least some of the coils (102) in the set (100) of first coils (102) have magnetic cores (104) to enable power transfer by magnetic induction as the magnetic cores (104) of the set (100) of first coils (102) move relative to a said set (200) of second coils (202). A controller is configured to enable each coil (102) in the set (100) of first coils (102) to be selectively powered as the set (100) of first coils (102) move relative to a said set (200) of second coils (202) in order to enable transmission of information to a said set (200) of second coils (202).
