In the field of opto-electronic technology, a three-dimensional light-emitting diode light-emitting plate is described. An upper sleeve assembly includes an upper and lower ball bearing press fitted therein and a lower sleeve assembly includes an upper ball bearing press fitted therein, the first and second sleeve assemblies being press fitted to a shaft having a ball bearing press fitted at the base of the shaft. Development Events occur within Project Development Phases, which Phases may vary in number and kind depending on the end product. Also, at the first transmit power setting and then at the second transmit power setting, a spectrum analyzer may measure actual power of the signal transmitted by the wireless terminal. The relative displacement of the tissue is determined by the instantaneous tissue velocity of the sample volume.
