Abstract: An appliance warning system comprises a floor pad for location on or adjacent a device such that a user must stand on the floor pad in order to normally use the device. The floor pad has at least one switch movable between an open position when no weight pressure is detected on the floor pad and a closed position when the switch is activated by weight pressure detected on the floor pad. A control circuit is connected operational between a ready state before the switch is activated to the closed position and a monitoring state after the switch is activated to the closed position. A warning device connected to the control circuit is activated when the control circuit determines that the switch has been in the open position for a preselected period of time after having been in the closed position.

Abstract: A medical diagnostic and communications apparatus with audio output comprises an electronic processor for processing stethoscope signals and secondary audio signals. An electronic stethoscope sensor is contained within a housing for transducing body sounds to electronic signals, and is operatively connected to the electronic processor. One or more secondary audio signal sources operatively connects to the electronic processor. A common audio output is connected to electronic processor to convert electronic stethoscope signals or secondary audio signals to acoustic output. These sounds may be produced separately or mixed.
