    摘要： The present invention provides a wireless identification system (100, 200) for identifying objects (150, 250), the wireless identification system (100, 200) comprising a uniquely structured pattern (101, 201, 301) comprising predefined dielectric properties and configured to be attached to the object (150, 250), a signal emitter (102, 202) configured to emit a wireless signal (103, 203) into an object space (104, 304) that is configured to accommodate the object (150, 250) with the uniquely structured pattern (101, 201, 301), a signal receiver (105, 205) configured to receive from different positions (106, 107, 206, 207) around the object (150, 250) a superimposed signal (108, 208, 215) caused by a superimposition of the emitted wireless signal (103, 203) and a scattered signal (109, 209) as scattered by the uniquely structured pattern (101, 201, 301), and a signal processor (110, 210) configured to reconstruct the structure of the uniquely structured pattern (101, 201, 301) based on the received superimposed signal (108, 208, 215).

    摘要： The present invention refers to a method for determining materials of a material composition (2). The inventive method comprises the steps: Providing a material composition (2); Biasing the material composition (2) with an electric field, wherein at least one parameter of the electric field is varied; Detecting values representing the dielectric property of at least one of the materials of the material composition (2) in dependency of the varied parameter; Transforming the detected values in representing values; Matching the representing values with data base values provided in a data base, wherein the data base values are representing specific materials; Outputting data or signals representing the material or materials matching with the data base values. The present invention further refers to a system or device for executing the before mentioned method.

    摘要： The present invention provides a hand-holdable electronic device (200) at least comprising at least two antennae (202a, 202b, 202c, 202d) and a signal processing unit (not visible in Fig. 2). During operation of the device, the antennae (202a, 202b, 202c, 202d) transmit and receive from each other electromagnetic waves in the microwave and/or radio frequency parts of the electromagnetic spectrum. The signal processing unit receives from each of the antennae a respective electrical signal, which represents the electromagnetic waves transmitted by the antennae and received by a respective one of the antennae, and analyses a scattering matrix of the transmitted and received electromagnetic waves to determine an electromagnetic environment near to the hand-holdable electronic device (200), i.e. within less than about one metre of the device. The electromagnetic environment near to the device can be used to determine a disposition of the device; for example, whether the device is being held in one hand or two by a user. This information about the disposition of the device can be used to adapt the operation of the device accordingly. For example, if the device (200) comprises a touch-sensitive display screen (203), the location and/or orientation of information displayed on the display screen may be varied according to the disposition of the device. The antennae are preferably disposed in a border (201) of the device (200), surrounding the touch-sensitive display screen (203), with members of a pair of antennae disposed on opposite sides of the device from each other. The sensitivity of the device to its electromagnetic environment and the spatial and/or temporal resolution thereof which the device can achieve can both be increased by increasing the number of antennae. The present invention also provides a corresponding method of determining an electromagnetic environment near to a hand-holdable electronic device.
