Abstract

One of the embodiment of present invention includes at least one transmitter-receiver set including a transmitter and a receiver opposed with an object to be measured therebetween; and a transmission device that estimates the amount of the object based on the attenuation of electromagnetic waves that are transferred between the transmitter and the receiver of the transmitter-receiver set, and transmits information on the estimated amount of the object to be measured.

Claims

1. An information provision system comprising:

at least one transmitter-receiver set including a transmitter and a receiver opposed with an object to be measured therebetween; and

a transmission device that estimates an amount of the object based on the attenuation of electromagnetic waves that the transmitter-receiver set transfers between the transmitter and the receiver, the attenuation of the waves occurring while being transmitted between the transmitter and receiver, and transmits the information on the estimated amount of the object to be measured.

2. The information provision system according to claim 1 affixed to a container that contains the object to be measured.

3. The information provision system according to claim 1, comprising

a plurality of transmitter-receiver sets, wherein

at least one of the transmitter-receiver sets is disposed such that a first line connecting the transmitter and the receiver thereof crosses a second line connecting the transmitter and the receiver of a second transmitter-receiver set.

4. An information provision system comprising:

at least one transmitter-receiver set including a transmitter and a receiver opposed with a space for an object to be measured therebetween; and

a controller that determines whether or not the object to be measured is placed on the space on the basis of the attenuation of electromagnetic waves that the transmitter-receiver set transfers between the transmitter and the receiver thereof, the attenuation of the waves occurring while being transmitted between the transmitter and receiver, and outputs the information on the determination result.
