A poultry raising system includes: an imaging unit configured to capture an image of an inside of a poultry house; and a monitoring unit configured to determine a variation in density of chickens present in a particular region in the image captured by the imaging unit, and monitor the variation determined. The particular region is at least part of the image.

Poultry raising system, poultry raising method, and recording medium

The faucet includes a detector including: a frequency analyzer to convert a sensor signal into a frequency domain signal, and extract, by use of a group of individual filter banks with different frequency bands, signals of the individual filter banks from the frequency domain signal; a recognizer; and a database device, for storing sample data. The recognizer performs a recognition process of detecting a detection object based on detection data containing a frequency distribution of signals based on the signals of the individual filter banks. The recognizer performs the recognition process based on comparison between the detection data and the sample data.

A signal processing device () includes an amplifier (), an A/D converter () and a signal processor (). The amplifier () amplifies a sensor signal that is supplied from a radio wave sensor () and depends on a motion of an object. The A/D converter () converts the sensor signal amplified by the amplifier () into a digital sensor signal. The signal processor () converts the sensor signal output from the A/D converter () into a frequency-domain sensor signal by Discrete Cosine Transform processing, estimates a background signal contained in the frequency-domain sensor signal, based on an error signal obtained from the sensor signal and a reference signal which is white noise, and determines a filter coefficient according to the estimated background signal, thereby operating as an adaptive filter for removing the background signal from the sensor signal in the frequency domain.

Signal processing device

A radio receiving apparatus of the present invention is for receiving a radio signal having pulsating signals occurring at specific periods, wherein the radio receiving apparatus corrects signal levels received during communication in individual regions into which each of the aforementioned periods is divided based on signal levels received in the individual regions under conditions where the radio signal is not received. As a result of this correction, the radio receiving apparatus of the present invention can decrease the influence of noise having periodicity and improve reliability of communication.
