A backpack-carried digital nose that sniffs out improvised explosive devices(IEDs) and other threats promises to ease checkpoint duty for troops stationed in hot spots around the world.

Developed by Scent Detection Technologies(SDT)，a small privately owned company based in Herzliya, Israel，the militarized mininose—trademarked MN- 2000-MIL—detects and identifies IEDs，rigged vehicles(伪装的车辆) and other hazards by the vapors or traces particles(微粒)left on skin，machinery and personal belongings.

Soon to enter mass production，the MN2000-MIL is a ruggedized(强化的) version of the firm’s MiniNose-2000 designed for use by law enforcement and security personnel.It is a second-generation version of the firm’s MN1000，which has been purchased by several Asian countries，including China，which introduced the system for the Beijing Olympics.

Like its former products，the system is based on company-patented High-Frequency Quartz Crystal Microbalance(HFQCM) technology that digitally imitates mammalian olfactory(嗅觉的) sense capable of learning to recognize new substance.

“It works like a supersensitive digital nose able to detect very low nanolevel(纳米级) amounts of any source substance，” SDT Chief Executive Officer Bengal said.“We then teach it to identify substances by matching them with a library of threats we’ve programmed into the machine.”

“The entire analysis process，” Bengal said，“takes 8 to 26 seconds，depending on the substances.”

Unlike other trace detection systems on the market，which are based on radioactive-source Ion Mobility Spectrometry technology，SDT’s QCM-based system contains no radioactive parts.

“Ion Mobility Spectrometry systems are essentially radioactive，” Bengal said.“You need special licensing to sell them and specially trained personnel to service them.But we’re using essentially green technology.You don’t need trained technicians to operate or even open our machines.”

In the two years since SDT began producing the MN2000 for the homeland security market，the system has demonstrated its ability to operate for months at a time without servicing or technical repairs.Bengal said the new military model will be much stronger，as it was designed to operate in dust，heavy fog and otherwise extreme field conditions.

One of the keys to successful time management is prioritizing tasks and distinguishing optional activities from the essential.Whether you are writing different “to-do’s”in different colors of ink or are giving each list item a priority ranking，your decisions about the importance of activities will have a huge impact on how you spend your day.

Most of those who run their own business tend to develop a deep and strong commitment to work and to the overall success of their endeavors.Long hours are a norm，sleep appears to be optional and almost every effort is poured into growing the business.

However，those who overemphasize work-related activities at the expense of truly essential projects may actually see their time management collapse.

That’s because neglect of essential projects will make life，overall，less meaningful and enjoyable.At some point，the mere process of chasing after money will no longer subconsciously justify the disregard of some very important things.

What are these essential tasks? They have nothing to do with record keeping，taxes，improving advertising copy or handling customer relations.Instead，they involve being a good father，a good wife and a good person.These chores are the ones that give us a reason to have our financial goals.We work in the first place for these things.

Your essential projects will be determined by your own personal preferences and lifestyle.Those with strong religious beliefs will consider worship essential.Those who feel the need

to exercise in order to relax will label physical activity as an essential activity.

It’s too easy to let these important things slide to the back burner when one is under pressure to produce or to grow their business.One invests a great deal of himself or herself in creating a successful project and it can feel as though spending every waking hour at work is more important than virtually anything else.

This perspective，however intuitive it may seem to one looking for ways to improve his or her time management skills，is actually a dead end.Over time，one will notice their motivation for work-related efforts slipping away.That inevitability arises from a subconscious recognition of life’s declining value，possible feelings of guilt，and a recognition that one is simply not meeting his or her most important responsibilities and commitments.

As you triage your activities as a part of your time management strategies，resist the temptation to elevate those tasks directly related to working above other truly essential responsibilities.By maintaining a proper balance you can invigorate(使有活力) your efforts and live a fuller，more meaningful life.

Work isn’t incompatible(矛盾的) with being a fulfilled person.On the contrary，a great work ethic and a successful business can lead to a great deal of fulfillment.However，when important non-work tasks are classified to the bottom of a “to-do”list，it surely results in negative consequences.

Looking back at my younger years，I am sometimes amazed at how life has turned out.Nothing is exactly what I had originally planned for.The only thing that stays the same is who I am，my values，and my interests.If I could go back in time and hang out with my younger self for a day，here’s what I would tell her.

1．Everything happens for a reason.

Without mistakes and failure，you would never have learned.Without pain，you would never have grown.So don’t stress or think that life is unfair because everything happens for a reason.And only time will tell what it will teach us.

2．Focus on one thing at a time.You can have it all but not all at once.

It is not surprising that many of us are doing too many things at once.We need to make ends meet.But if you are working three jobs at a time，it is not likely that you will succeed at any of them.You have to keep your eyes on the big picture.You have to ask yourself what exactly you want to achieve for the next 10 years.Focus on one thing at a time.Achieve your goals one by one.

3．You can plan in advance，but your plan will definitely change when the time comes.

You can plan in advance because sometimes planning in advance can give you a clearer direction of where you want to go.However，plans will almost always change，so be prepared!

4．Trust your instincts(直觉)．

Don’t worry too much about a decision you have to make.Just do what feels right.You know what you want.You might consult other people.But deep down, you know what you want.Do what makes you happy.Because at the end of the day，even if you follow logic，you will want to quit and follow your heart.

5．It’s okay to be unsure about your purpose in life.

You might be graduating or have hit a turning point with your career.You might feel a bit lost and unsure of where to go.It’s okay.Go out there and try as many different things as you can.Don’t ever feel like you’re wasting your time.Enjoy the journey.Don’t rush.Every little path will lead you somewhere.And looking back，you will be able to connect the dots.It will all make sense.

6．Don’t try too hard with people.

Don’t worry if you feel like it’s hard to make new friends.Just be yourself and be as open as you can.It might take a while until you find new best friends and a mate for life，but when you do，you will know it.It’s not hard work.So，just do your thing and be yourself.
