A radiation device is wirelessly connected to a radiography device that generates dynamic image data and which controls sequential radiation. The radiation device includes a signal generator and a first determiner. The signal generator generates (i) first pulse signals emitted by the radiography device, (ii) second pulse signals synchronized with a first count value obtained by counting up the first pulse signals, and (iii) a second count value obtained by counting up the second pulse signals. The first determiner determines whether to start radiation based on a delay time which is a difference between a first time point count value and a second time point count value. The first time point count value indicates a time point at which a radiation permission signal is transmitted. The second time point count value indicates a time point at which the radiation permission signal is received.

An interactive object system includes an interactive object and a source of electromagnetic radiation, e.g., an external source. A power harvesting device of the interactive object receives and harvests power from the electromagnetic radiation to power a special effect system of the interactive object. In an embodiment, the interactive object includes a retroreflective material that reflects electromagnetic radiation, which may be of a same or different wavelength as the electromagnetic radiation from which power is harvested. The interactive object system detects the reflected electromagnetic radiation, which may be used to trigger one or more additional actions related to the interactive object.

The present disclosure relates to parameter optimization. A parameter optimization method may include acquiring an initial exposure parameter usable by the medical device for performing exposure; acquiring contour information of a test subject and initial relative position information of the test subject relative to the examination component; determining an estimated attenuation amount of rays passing through the test subject based on the initial relative position information, contour information of the test subject, and real-time position information of the examination component, the estimated attenuation amount representing the degree of attenuation of rays from the radiation source after passing through the test subject, and the real-time position information of the examination component being position information of the examination component acquired in real time; and updating the initial exposure parameter based on the estimated attenuation amount. The method can reduce the number of exposures and improve the operating procedure and efficiency.

Borehole radar systems send a radar pulse into the subterranean formation using a transmitter. The radar pulse is reflected back when it encounters a formation feature that has a different electromagnetic property. The receiver receives the reflected energy back. However, in a highly conductive rock or in the presence of highly conductive fluids in the borehole region, the radar pulse is not transmitted far enough with sufficient intensity to be detected by the receivers. This technology provides a design for a device which amplifies the radar transmitted power, using a metamaterial. The metamaterial enhanced device is designed for an electric source frequency ranging between 1-5 GHz. Further, a metamaterial based antenna design achieves a directivity over D=20. This provides high intensity far field radiation into the subterranean formation which can be detected by the receivers with high signal to noise ratio (SNR).
