Abstract: An impression analysis system includes: an input obtainer that receives an evaluation target image; and a hardware processor, wherein the hardware processor: extracts a low-order image feature amount, and a high-order image feature amount, from the evaluation target image, and compares data obtained by extracting a low-order image feature amount and a high-order image feature amount from a reference image associated with an impression evaluation, with data of the image feature amounts extracted by a feature amount extractor, and calculates a similarity between the evaluation target image and the reference image.

Abstract: A saliency analysis system includes: an input receiver that receives an evaluation target image; and a hardware processor, wherein the hardware processor extracts low-order image feature amounts and high-order image feature amounts, from the evaluation target image, and calculates saliencies in the image, based on the low-order image feature amounts and the high-order image feature amounts.

Abstract: A design evaluation device (100) includes a sensitivity information acquisition unit (111) that acquires sensitivity information of an evaluator with respect to a design of an object, an attribute information acquisition unit (112) that acquires attribute information of the evaluator, and a purchase expectation degree prediction unit (115) that predicts a purchase expectation degree with respect to the design of the object on the basis of the sensitivity information and the attribute information.

Abstract: This tag reader can be applied to a chipless RFID tag having a plurality of resonance frequencies that are associated with identification information. The tag reader is provided with: a radiation unit that radiates electromagnetic waves within a predetermined millimeter wave or microwave frequency band so as to cause sweeping of the radiation frequency; and a detection unit that detects the plurality of resonance frequencies of a chipless RFID tag on the basis of the reflection characteristics of waves reflected from the chipless RFID tag when the electromagnetic waves are radiated.

Abstract: Disclosed is a fuel cell apparatus which can continue stable performance, can generate an electric power for a long period, and has a long service life. The fuel cell apparatus comprises: a fuel cell body comprising a power generation unit which can generate an electric power through the reaction between hydrogen and oxygen and a hydrogen generation member which can generate hydrogen through the reaction with water produced upon the generation of the electric power and can supply hydrogen generated to the power generation unit; and a reduction control unit which can control so as to reduce the hydrogen generation member that has been oxidized through the reaction with the produced water.

Abstract: The fuel cell device is provided with: an electricity-generating unit having a fuel electrode (102), an air electrode (103), and an electrolyte film (101) sandwiched between the fuel electrode (102) and the air electrode (103); a hydrogen-generating member (104) that, by means of an oxidation reaction with water, generates hydrogen for supplying to the fuel electrode (102) of the aforementioned electricity-generating unit; a heater (105) that heats the hydrogen-generating member (104); a temperature sensor (106) that detects the temperature of the hydrogen-generating member (104); and a temperature control unit (20) that controls the temperature of the hydrogen-generating member (104) in response to the detection results of the temperature sensor (106). The temperature control unit (20) stops the passage of electricity through the heater (105) when it has been determined that the temperature of the hydrogen-generating member (104) is at least a predetermined temperature.
