Abstract: A handheld terminal that makes it easy to identify the position of a locator. Said handheld terminal (100) is provided with the following: a wireless unit (130) that receives a radio signal transmitted by the locator; an RSSI detection unit (150) that measures the strength of the received radio signal; a distance-information determination unit (211) that, on the basis of the measured received signal strength, determines distance information that indicates a distance level between the wireless unit (130) and the locator; and an annunciation unit (240) that outputs the determined distance information.

Abstract: When a subject is pressed by a plate and an acoustic wave is received by a probe via the plate, the acoustic wave is refracted because of the difference between a sound velocity in the subject and a sound velocity in the plate. When the refraction is not considered, a reduction in resolution occurs. A correction table or a correction formula for correcting image distortion associated with refraction is provided. After image information is acquired, new image information is acquired in accordance with the correction table or the correction formula, and is displayed.

Abstract: A radio communication apparatus and transmission power control method are disclosed, which can maintain communication with handsets while avoiding an increase in radio interference to another radio communication system as much as possible when radio communication is performed with one or more handsets. The handset transmits a communication start request signal to a base unit. Upon verifying the reception of the communication start request, the base unit measures the RSSI level of the communication start request signal transmitted from the handset, determines a transmission power value based on a power control table that has been updated with the measured RSSI level, and controls the transmission power of a control signal transmitted to the handset.

Abstract: Disclosed is a radio communication apparatus capable of stopping useless transmission of a calling signal to a locator. A calling apparatus transmits, using a near field radio communication apparatus, a calling signal to a locator attached to an item and outputting a notification sound, the calling signal being used for calling the locator. The calling apparatus periodically stands by for reception of a response signal from the locator using one slot when performing consecutive transmission of the calling signal to the locator using a plurality of slots. The calling apparatus stops the consecutive transmission of the calling signal by being triggered upon reception of the response signal from the locator.

Abstract: When a subject is pressed by a plate and an acoustic wave is received by a probe via the plate, the acoustic wave is refracted because of the difference between a sound velocity in the subject and a sound velocity in the plate. When the refraction is not considered, a reduction in resolution occurs. Weights for signals or virtual wavefronts corresponding to the signals to be added to one another are determined using a thickness of the plate, the sound velocity in the plate, the sound velocity in the subject, positions of image elements (pixels or voxels) for image information, and arrival times of the acoustic wave from an object that is a sound source. The signals or the virtual wavefronts corresponding to the signals are added to one another, thereby acquiring the image information.
