7. Safety apparatus for preventing injurious engagement of machinery with a user and clothing and accouterments thereof within a predetermined volume comprising:
-
a sensor having two modes of operation;
a reference sensing mode of operation for sensing the boundaries of the predetermined volume; and
an engagement prevention mode of operation for sensing the presence of a user and clothing and accouterments thereof within the predetermined volume; and
control apparatus responsive to outputs from said sensor in both of said modes of operation for preventing operation of said machinery when the presence of a user and clothing and accouterments thereof within the predetermined volume could cause injurious engagement. - View Dependent Claims (8, 9, 10, 11, 12, 13, 15, 16, 18, 19)
