Abstract: A wavelength calibration method for a microring filter includes selecting N wavelengths from M wavelengths, and performing operations on the microring filter for each of the N wavelengths, thereby obtaining N sets of calibrated voltages, and obtaining, based on N sets of calibrated voltages, M?N sets of calibrated voltages corresponding to M?N wavelengths of the M wavelengths. The operating include adjusting thermal tuning power of the plurality of microrings in response to one set of voltages, and obtaining a plurality of sets of voltages that enable monitored optical power to have an extreme value, and using the plurality of sets of voltages as a reference, adjusting the thermal tuning power of the plurality of microrings in response to another set of voltages, and determining one of the N sets of calibrated voltages from the plurality of sets of voltages.

Abstract: A wavelength calibration method, apparatus, and system is disclosed. The method includes: selecting sonic wavelengths from a plurality of wavelengths, and performing the following operations on a microring filter for each of the some wavelengths, to obtain sets of calibrated voltages of the some wavelengths: (1) adjusting thermal tuning power of multiple microrings by using one set of voltages, and obtaining multiple sets of voltages that enable monitored optical power to have an extreme value, and (2) using the multiple of sets of voltages as a reference, adjusting the thermal tuning power of the multiple microrings by using another set of voltages, and determining one of the sets of calibrated voltages, which enables the monitored optical power to converge, from the multiple sets of voltages; and then, obtaining, through calculation based on the sets of calibrated voltages of the some wavelengths, sets of calibrated voltages of other wavelengths.

Abstract: The distribution and/or ratio of Thymine, Cytosine, Adenine and Guanine of a DNA sequence from a target organism are organized and analyzed. The result is then used to determine the possible impacts the target organism may have in a host such as a human body. The corresponding treatment and prevention strategies may also be determined. The goal is to provide an effective way to diagnose, treat and prevent diseases such as infectious diseases, to test the safety of food and drugs, and therefore to create natural and effective solutions for health care and food supply. For example, a DNA analysis method configured according to the invention receives a DNA sequence input and converts it into a reassembled sequence. A result based on the reassembled sequence may then be output. Determination of the analysis result, treatment and prevention strategies may also be output.

Abstract: A mechanical puppet show apparatus provides a base unit supporting on its upper surface (stage) one or more mechanical puppets. The puppets are interconnected with a circuit for motion actuation in accordance with a stage play that is programmed into a memory device and controlled by a digital control unit. Manual, remote control and verbal signals may be received for interactive action of the puppets with the audience. A method for use of materials downloaded by packet data transfer from the Internet may be employed in programming.
