Abstract: A battery diagnostic apparatus and a battery diagnostic method that are capable of accurately determining a deteriorated state of a battery and enabling use of the battery immediately before or near the end of the battery life are provided. The battery diagnostic apparatus includes a power supply monitoring unit 5 configured to detect that a power supply voltage has changed from less than a predetermined voltage to equal to or more than the predetermined voltage, and a controller 4 configured to measure a battery voltage in a predetermined period after the detection that the power supply voltage is equal to or more than the predetermined voltage, calculate electric power associated with a remaining capacity of the battery 1 based on the battery voltage, and perform deterioration determination of the battery 1 based on the electric power associated with the remaining capacity of the battery 1.

Abstract: Radio equipment includes a substrate on which a first antenna for near field communication is provided, a base portion on which the substrate is erected, and a cover portion configured to be attached to the base portion so as to cover the substrate. The cover portion includes an opposing portion configured to oppose the first antenna and a non-opposing portion disposed closer to the base portion than the opposing portion in a direction in which the substrate is erected. A distance from an outer surface of the cover portion to the substrate at the opposing portion is shorter than a distance from the outer surface of the cover portion to the substrate at the non-opposing portion.
