An information processing apparatus includes a communication interface and a controller. The communication interface receives, from a sensor container, information indicating an orientation of the sensor container. The controller, based on the information indicating the orientation of the sensor container, calculates a calculated value indicating a remaining amount of contents of the sensor container. The controller determines an estimated value of the remaining amount on the basis of the calculated value. The communication interface transmits the estimated value indicating the remaining amount to an external device. When the calculated value indicating the remaining amount decreases by a first predetermined value or more within a predetermined time period, the controller does not perform the determination of the estimated value on the basis of the calculated value.

A high-frequency module according to the present embodiment includes a substrate, a circuit board, and a waveguide. The substrate has an input-output portion for high-frequency signals on one surface thereof. The circuit board has a dielectric waveguide line with its end face exposed, and is placed on the one surface of the substrate such that a virtual plane extending beyond the end face is intersected by the one surface of the substrate. The waveguide has openings at ends thereof, in which one of the openings is connected to the end face of the dielectric waveguide line, and the other opening is connected to the input-output portion of the substrate.

High-frequency module and method of manufacturing the same, and transmitter, receiver, transceiver, and radar apparatus comprising the high-frequency module

A high-frequency module according to the present embodiment includes a substrate, a circuit board, and a resonator. The substrate has an input-output portion for high-frequency signals formed on one surface thereof. The circuit board includes a dielectric waveguide line with its end face exposed, and is placed on the one surface of the substrate such that a virtual plane extending beyond the end face is intersected by the one surface of the substrate. The resonator includes input-output end portions for high-frequency signals at ends thereof, in which one of the input-output end portions is connected to the end face of the dielectric waveguide line, and the other thereof is connected to the input-output portion of the substrate.

The invention relates to a small and low-voltage operable dielectric waveguide device. First and second electrode are embedded in a dielectric part and are formed to be thinner than a skin depth for a frequency of electromagnetic wave propagating along a first dielectric part included in the dielectric part. Thereby, even if the first and second electrodes are arranged to be in contact with the first dielectric part, the propagating electromagnetic wave can transmit the first and second electrodes, and therefore the electromagnetic wave can propagate without being cut off and there is no influence on waveguide modes of the electromagnetic wave. Further, in a state where a transmission loss due to the embedded of the electrode is suppressed, an electric field with large electric field strength can be applied to the first dielectric part by the first and second electrodes, and a small and low-voltage operable dielectric waveguide device can be achieved.
