Abstract: An electronic data input apparatus comprises a receptacle, a tube, a housing for electronic components, and a harness. The receptacle is operable for use in a user's mouth. The tube connects the receptacle to the housing, which is attached to the harness. A user wears the harness on the upper part of the torso, such that the receptacle is accessible to the mouth. A cable connects the electronic component housing to a computing element and establishes serial communication from the input apparatus to the computing element. The apparatus may provide the same function as a conventional mouse pointing device by allowing the user to control the motion of a pointer on an electronic display by breathing in to and out of the receptacle.

Abstract: An improved treadmill comprises a motor driven endless belt, sensors located below an upper run of the belt for sensing the position of a user, and a controller for controlling the speed of the belt in accordance with the position of the user relative to the sensors. The detection or lack of detection of the user by the sensors can cause the belt to accelerate, decelerate, remain at a constant speed, or stop. A proper sequence of user detections by the sensors permits the controller to initiate an automatic speed adjusting system. The controller also provides a safety system for stopping the belt. In one embodiment, the controller stops the belt upon a lack of the sensors detecting the user. In another embodiment, a safety sensor is mounted on an upper surface of a member located proximate the belt, and the controller stops the belt when the safety sensor senses the user.
