358 Understanding Smart SensorsManchester a digital signaling technique in which there is a transition inthe middle of each bit time. A1isencoded with a high level during the firsthalf of the bit time, and a0isencoded with a low level during the second halfof the bit time.maximum operating temperature the maximum body temperature atwhich the sensor will operate for an extended period of time with acceptablestability of its characteristics. This temperature is the result of the internal orexternal heating or both and should not exceed the maximum value specified.maximum power rating the maximum power that a sensor will dissipatefor an extended period of time with acceptable stability of its characteristicsmechatronics the synergistic combination of precision mechanical engineering,electronic control, and the systems approach for designing productsand manufacturing processesmedia means of data transmission in a network, for example, two-wire,twisted-pair, coaxial cable, power lines, single-wire (with common ground),infrared, RF, fiber optic; also, the material used to transfer a pressure signalmesoscalemachinesmicrocodea scale of machines that is between MEMS and conventionalmachine instructions built permanently into controller circuitrymicrocontroller a single integrated circuit that contains a CPU, memory, aclock oscillator, and I/O.
