Abstract: An apparatus for encouraging or instructing personal hygiene having a non-animated character figure of a substantially three-dimensional configuration and an audio producing means in combination with an electrically operated toothbrush. A toothbrush is supported by the character figure. Removal for use of the toothbrush activates the audio producing means for a defined period. The audio producing means recites a melody or message or combination thereof. The audio producing means will continue to operate when deactivated when the toothbrush is returned to the character figure or when the audio producing means is manually deactivated, however, when deactivated the audio producing means continue to the end of the message or melody then in progress.

Abstract: Apparatus for conducting Ordering Trials including a set of counters each incorporating an electrical circuit element which covertly identifies that counter and a box having locations for receipt of the counters. The counters and locations are fitted with plugs and sockets which are interengageable and permit the circuit element to be connected to electrical read-out circuitry which includes circuitry for identifying which counter is in which location. An arithmetic unit operating according to a predetermined algorithm is connected to the output of the interrogation circuitry to provide a measure of the result of a trial. The invention is concerned with a form of interrogation circuitry which permits a direct digital readout to be attained.
