  • Publication number: 20240117984
    Abstract: Provided is an air conditioner including an indoor unit provided with a microphone element for receiving voice instructions, such that a voice instruction spoken by an operator is acquired with high quality and control based on the voice instruction spoken by the operator is likely to be ensured. The air conditioner includes an indoor unit, a transmission unit, and a reception unit. The indoor unit has a main body and a microphone element. The main body has formed therein a blow-out port through which air-conditioned air is blown out toward a space to be air-conditioned. The microphone element accepts a voice instruction captured from a voice capturing portion arranged at a position that deviates from a ventilation space through which the air blown out from the blow-out port flows, in such a manner as to face the space to be air-conditioned. The transmission unit transmits the voice instruction accepted by the microphone element to an outside as a signal.

  • Patent number: 7694890
    Abstract: A passive ultrasonic tag is provided and an ultrasonic reading system is constructed more simply and records and/or reads information more reliably by using ultrasonic waves for transmission/reception. A passive ultrasonic tag according to a first embodiment of this invention includes a tag body. The tag body has two or more holes disposed extensively on a surface of the tag body. The holes have bottoms at predetermined depths from the surface of the tag body. The depths of at least two of the two or more holes are set to different values. As a result, when a three-dimensional range including surfaces and bottoms of the two holes is scanned using ultrasonic waves, the ultrasonic waves are reflected in different manners on the basis of the depths of the two holes. This allows information to be recorded and read.
