"E.coli Time Manager" from CHIBA team is delayed switch system by using AHL concentration. Futher application of this system is now under planning as follows.
1. "security-preset message manager"
When we compose a set of delay switch with different timing, the time-sequencial gene expression takes place automatically. This system is utilized for time-sequential appearance and erasure of message written by E. coli ink, like GFP.

It is very useful for security-certified message document.

2.　"Expiration date messanger"
Food is getting worse when it is contaminated by bacteria. The bacteria activity is influenced by temperature. When our time manager package is located near the food, the manager can tell us the GFP expression by the accumulation of AHL produced by senders which experience with the food-cultured bacterium.
This is a novel expiration date messenger!
Not only the temperature, but also other input stimuli can be involved to our bacteria system for constucting the accumulation messenger.

3. "Sequencial timer"
When we use the delayed switch with different timing, we can preset the sequence of the switchrs. It will be "Automation of bacteria factory"!

-今までの賞味期限は規定された保存状態でどれだけの時間、食品の安全が保証されるのかというものだった。食品がある一定温度にどれだけ放置されたかを計ることで、それに対する菌の活性の経緯知ることが出来る。これが出来ればより本質に近い賞味期限を提示することができるだろう。

-'''セキュリティーシステム'''
-GFPなどの目で確認できる文字（情報）を浮き上がらせてから、時間をおいて周りの菌にGFPを発現させる。<br>
-そうすとことによって、最初の文字（情報）を塗りつぶす。<br><br>
-'''賞味期限装置'''
-食品が傷む原因は細菌の活動が影響している。細菌の活動は温度に依存するので、温度変化を入力とする。<br>
-食品が傷む前にGFPを発現して私たちに知らせてくれる。<br>
-どれだけ時間変化が長くとも、短くとも私たちに知らせてくれる。<br>
-'''積分装置'''
-消えてしまう入力（たとえばUV被ばく、汚染物質）をセンダーがAHLを出すことによって入力を記憶しておく。<br>
-AHLがたまり、危険量に達したことを知らせてくれる。<br>
-'''順番スイッチ'''
-発現時間の異なるdelayed　switchを組み合わせることで、決められた順序が変わることなく順々にスイッチが入っていく自動的なシステムが作れる。
