Abstract: A sensor 2 of a data collection system 2 is designed to make, in a predetermined environment, an operation of writing output data of a sensing circuit 24 into a non-volatile memory 22 as reference-value data, and, in a measurement environment, an operation of transmitting output data of the sensing circuit and reference-value data stored in the non-volatile memory, under the control of a memory control section 25, thereby selectively performing by itself the data-writing or data-transmitting operation without receiving instructions from a readout device.

Abstract: A sensor apparatus (2) has a coil (20) for receiving an electromagnetic wave energy applied from outside, a power supply section (21) for generating an internal power supply from the electromagnetic wave energy, and a sensing circuit (24) having a sensor device mounted thereon. The sensor apparatus receives and decodes a tolerance value intrinsic to the sensor apparatus and set by a configuration/read-out apparatus (1) based on the output of the sensing circuit of the sensor apparatus placed under a prescribed environment, and stores the tolerance value in a nonvolatile memory (23). The sensor apparatus placed under a measuring environment sends out the output of the sensing circuit and the tolerance value to the configuration/read-out apparatus.

Abstract: A non-contact temperature measuring apparatus is provided with spherical semiconductors mounted on a measurement object and a data collector disposed out of contact with the measurement object. Each spherical semiconductor has an electronic circuit which is operable using internal power created from electromagnetic energy supplied from the data collector, to thereby obtain temperature information. The data collector contactlessly determines a temperature of or a temperature distribution across the measurement object based on pieces of temperature information transmitted from the spherical semiconductors specified by pieces of identification information sequentially transmitted from the data collector.

Abstract: An integrated circuit device has a device main body 1 having a predetermined circuit function of providing an output corresponding to an input thereto, and is provided with a power supply section 4 for receiving through a coil 3 electromagnetic wave energy applied from outside to generate predetermined internal electric power required to operate the integrated circuit device. The integrated circuit device further includes a calibration data acquisition circuit (operation control section 5) for detecting the output of the device main body 1 operated in a predetermined operating environment to obtain calibration data on the device main body, and a nonvolatile memory 6 for storing the calibration data.

Abstract: A spherical semiconductor device 1a comprises three spherical semiconductors 10, 20 and 30, which are connected together. An electronic circuit is formed on the surface of the central spherical semiconductor 10, among the three spherical semiconductors, while a coil 21 and a capacitor 31 are formed on the respective surfaces of the other spherical semiconductors 20 and 30, respectively. Since the spherical semiconductors 20 and 30 at the opposite ends are independent of the central spherical semiconductor 10, an insulating film on the coil 21 never influences the properties of the electronic circuit of the central spherical semiconductor 10, and the capacitor 31 can secure a capacity large enough to maintain satisfactory operating power for the spherical semiconductor device 1a. Since the three spherical semiconductors 10, 20 and 30 are manufactured in different processes, moreover, the productivity of the spherical semiconductors cannot be lowered by differences between manufacturing processes.
