Abstract: A case for a powered toothbrush comprises a housing having an interior for receiving a powered toothbrush, and a cover, wherein the cover substantially obfuscates the interior but is sufficiently light-transmissive to communicate the presence of an indicator from within the interior. Also provided is a powered toothbrush and case system.

Abstract: An activity amount-related information display apparatus according to the present invention acquires value information indicating exercise intensity, activity amount, or expended calories of a measurement subject. On a display screen, a circle corresponding to one day is set, and time divisions each indicating elapse of a unit time in the one day are set clockwise around the circle. Value information is displayed as a graph composed of a collection of bars that extend outward in a radial direction around the circle and have lengths of multiple levels, the lengths each corresponding to a value indicated by the value information for a unit time.

Abstract: A gait posture meter evaluates a gait posture of a measurement subject, and includes an accelerometer affixed to a centerline of a measurement subject's waist area, an evaluation unit that repeatedly finds an evaluation amount quantitatively expressing a gait posture of the measurement subject based on an output of the accelerometer in each of predetermined unit periods within a predetermined continuous walking period of no greater than ten minutes, and a display processing unit that displays the repeatedly-found evaluation amounts in time series in the display screen.

Abstract: An activity meter includes a body movement detecting unit, a display unit, a target activity amount acquiring unit, an accumulated activity amount calculation unit, an excess activity amount calculation unit, a converted value calculation unit that calculates a converted value representing an excess amount of activity by dividing burned calories corresponding to the excess amount of activity by a unit calorie count, where a standard calorie count of a predetermined food is the unit calorie count, and a display operation control unit that controls a display operation of the display unit such that the display unit displays a measurement result using the converted value.
