An angle-measuring system comprising at least one transmitter provided with a number of complementary signal-generating elements disposed in pairs and creating a pattern of signals. The machine has a first printing cylinder defining a first circumference and carrying a first number of rows of first image elements, each adjacent row of first image elements having a first circumferential separation. After measurement has begun, the hardness tester measures the value for the displacement, speed, or acceleration of the indenter during the process of approaching the sample. The TIP Bridge Bandages will be of considerable advantage over bandages used today in emergency services, clinics, operating and recovery procedures. The serial interface may interface at least one of the main controller and the data reading unit with the memory. The insulator pads have a stiffness modulus above 100 psi, preferably above 200 psi and most preferably above 300 psi.
