2. State of the Art
Safety of the user is a major concern in the design and manufacture of powered machines. Powered treadmills and like machines having exposed moving parts may injure a user who accidently or deliberately misuses the machine. The popular domestic use of such machines recommends use of means to prevent accidental activation by children, pets or others. In addition, the possibility of a user falling on or from a machine makes it desirable to have a mechanism by which the machine may be de-activated in such events. A mechanism to prevent or eliminate "surprise" activation is desirable. In addition, some means to automatically and immediately halt the machine in case of an accident is desirable.
