An ultrasonic transducer, an ultrasonic probe, and an image diagnosis apparatus perform an ultrasonic procedure. There is also included an illumination device, such as an LED or collection of LEDs which can illuminate the material. The preferred method linearly filters a received signal to form a first filtered signal, despreads and demodulates the first filtered signal and provides a plurality of symbol estimates for all corresponding code channels. The audible alert device may be programmed during a manufacturing step to exhibit a selected operation mode so that one circuit may be manufactured and programmed to operate in any of a number of operation modes or device configurations. The final step is pressing the metal board with different thickness to form a face with different thickness distribution. A solver optimizes product availability information in response to the material supply information, product supply rules and priorities.
