Abstract: An information notification device includes a longitudinal-data storage unit that accumulates, for a plurality of samples, longitudinal data indicating a temporal change in foot size of one sample, a user-data storage unit that stores user data containing a gender, an age, and a past foot size of a prediction target person, a foot-size prediction unit that predicts, based on a current foot size of the prediction target person and the longitudinal data, a change in foot size of the prediction target person in a period from a current point in time to a future point in time, and a notification processing unit that displays, on a display unit, the prediction of the change in foot size of the prediction target person in the period from the current point in time to the future point in time.

Abstract: A technique presents on a display a computer game character and a first scannable code (SC) scannable by a camera of at least a first user apparatus to cause a server to download to the first user apparatus a photo app operable to generate a photo of a first user and send the photo to the server, which alters the character in accordance with the photo. The character with the face altered is presented along with a second SC that can be scanned to cause the server to download to the first user apparatus a share app operable to select a second user apparatus to send an image of the character with the face altered in accordance with the photo such that the second user apparatus can display the character with the face altered in accordance with the photo. User options may be provided to alter the character or game.

Abstract: A floppy disk recording data regeneration system having a voltage-controlled delay circuit, voltage-controlled data phase shifting circuit and a loop filter made up of a first-stage low-pass filter with a first cut-off frequency, and a second-stage low-pass filter with a second cut-off frequency lower than the first cut-off frequency. The output voltage of the second-stage low-pass filter drives the voltage-controlled data phase shifting circuit, and the output voltage of the first-stage low-pass filter drives the voltage-controlled delay circuit. The amount of delay of the oscillation output pulse is adjusted by the voltage-controlled delay circuit to suppress the occurrence of read errors in the event of peak shifts. In the event of a wow and flutter fluctuation, the amount of shift in the phase of the read data signal pulse is finely adjusted to suppress the occurrence of read errors in subsequent stages.
