    Abstract: A reader includes: a transmission device that repeatedly transmits, at a cycle corresponding to the code length of a prescribed code string, an electromagnetic wave that is phase-adjusted with the prescribed code string; a reception device that receives the reflected wave from the object to be identified, cyclically overlaps a reception signal relating to the reflected wave at the cycle of the code length, and calculates the correlation value of the overlapped result and the prescribed code string; and a control device that controls the transmission device and varies the transmission frequency of the electromagnetic wave in a steplike manner to perform a frequency sweep within a prescribed frequency band, controls the reception device, causing the reception device to calculate the correlation value for each transmission frequency, and specifies the attributes of the object to be identified on the basis of the correlation value for each transmission frequency.

    Abstract: A method of interrogating an acoustic wave sensor comprises transmitting, by an interrogator, an interrogation radiofrequency signal to the acoustic wave sensor by way of a transmission antenna, receiving, by the interrogator, a response radiofrequency signal from the acoustic wave sensor by way of a reception antenna, and processing by a processing means of the interrogator the received response radiofrequency signal to obtain in-phase and quadrature components both in the time domain and the frequency domain, determining by the processing means perturbations of the obtained in-phase and quadrature components both in the time domain and the frequency domain and determining by the processing means a value of a measurand based on the detected perturbations.

    Abstract: A capacitive sensing identification tag includes a substrate and a touch sensing layer disposed on one side of the substrate. The touch sensing layer includes high-sensing regions and low-sensing regions with different shapes. Both the high-sensing regions and the low-sensing regions have different stacked conductive layers and dielectric layers. A difference between the high-sensing regions and the low-sensing regions is that each of the high-sensing regions contains a dielectric layer, while each of the low-sensing regions does not. The capacitive sensing identification tag achieves an effect of sampling and identification of a touch panel by a capacitive sensing quantity that is different from a capacitive touch panel. And the capacitive sensing identification tag will not cause a difference in color or light transmittance between the high-sensing regions and the low-sensing regions, so there is no visible difference between the high-sensing regions and the low-sensing regions.

    Abstract: A computer-implemented method for digitization of papercraft folding for creation of a papercraft model may include monitoring, via an RFID reader, a sheet provided with an array of RFID tags. Based on the RFID reader output, the occurrence of a fold performed on the sheet is determined. The method further includes determining fold properties of the occurred fold and storing the fold properties as a fold dataset of the occurred fold.
