Abstract: A processing device is provided for processing an image obtained by imaging the inside of the oral cavity for use in diagnosis of the inside of the oral cavity. The processing device includes at least one processor. The at least one processor performs processing for acquiring one or more determination images of a subject through a camera for capturing an image of the subject including at least a part of a user's oral cavity, determining a possibility of contracting a predetermined disease based on a trained determination model stored in a memory to determine the possibility of contracting the predetermined disease and the one or more acquired determination images, and outputting information indicating the determined possibility of contracting the predetermined disease.

Abstract: A spread spectrum demodulating device applicable to a spread spectrum communications system for demodulating a spread spectrum signal by inverse spread. A spread clock is directly recovered from a received spread spectrum signal to thereby generate a predetermined PN (Pseudo Noise) signal.

Abstract: A device for adjusting the orientation of an antenna for an earth station. A received signal from the antenna is delivered from an outdoor unit to a demodulator of an indoor unit to be demodulated thereby. In the indoor unit, a converter receives an automatic gain controlled voltage signal from the demodulator and converts it into a digital signal, and a controller converts the digital signal into a predetermined control signal to feed it to the outdoor unit over the cable. In the outdoor unit, a display responsive to the control signal indicates a particular level which corresponds to the automatic gain controlled voltage. A person, therefore, can adjust the antenna to an optimum orientation unassisted, i.e., while observing the display.

Abstract: A PSK demodulator uses a sweep controller to broaden a range in which synchronism may be captured. The invention uses a decision circuit jointly based on a received PSK signal and a recovered carrier wave for making a soft decision as to the correction required for synchronism. An error voltage is developed responsive to a phase error for causing the sweep controller to sweep when there is no synchronism and to remain fixed when there is synchronism. The resulting circuit eliminates false synchronism indications.

Abstract: An AFC/AGC circuit utilized in a receiving apparatus of a ground station for the satellite communication system comprising a digital AFC/AGC controller functioning such that;when the pilot signal is not received, the gain control voltage and the frequency control voltage are respectively set to appropriate values based on the predetermined data;when the pilot signal starts to be received, the gain and frequency control voltages are switched from the set values to the values obtained from the digital AFC and AGC processings, respectively;so long as the pilot signal is being received, the signal generated in the digital AFC and AGC processings are sampled by respective sampling clock signals and the gain and frequency control voltages are determined in accordance with the sampled data; andwhen the pilot signal stops being received, each of the gain and frequency control voltages is held at the value sampled by a last pulse of the sampling clock signal immediately before the stopping, respectively.
