Injection Molding

Shapes: Simple and Complex solid bulk shapes

Design Notes:
Best way to mass-produce small, precise, polymer components with complex shapes.
The surface finish is good
texture and pattern can be easily altered in the tool
fine detail reproduces well.

The Economics:
Capital cost are medium to high

The Environment:
Thermoplastic spurs can be recycled.

Well... seem like a bit messy below ... I will fix it later..

Hopefully.....

Anyway, what i am going to do should be like a device for finding ur naughty baby.

Don't Rush When They Walk

Babies develop at their own pace and nothing you say or do is going to change what that pace is. In fact, you can do more harm than good if you try to rush the development. Walking is a baby's first major move towards independence from you and once they start walking - they don't stop. In fact, running quickly follows.
Your baby needs to develop muscle strength and coordination during his or her first few months of life. They will learn to crawl, roll over and sit up and hold themselves upright in the sitting position. The average baby is starting to pull themselves up on things around 8 months or so. Now before you start glancing at the calendar and thinking your 9 month old isn't doing that - let me say again: there is nothing wrong with your baby.
My daughter did not walk until she was 18 months old. She didn't bother pulling herself up on things until after she was a year. In fact, she walked before she could crawl. How, you may ask, did she do this? Because she bounced everywhere she went. She did what we called butt scooting across the floor. Once she was able to hold herself up right in a sitting position - rather than crawl or try to pull herself up, she just bounced along the floor and got some lift at times.

Receptive Language
Learning to Listen, and to Understand Language

Birth
Language learning starts at birth. Even new babies are aware of the sounds in the environment. They listen to the speech of those close to them, and startle or cry if there is an unexpected noise. Loud noises wake them, and they become "still" in response to new sounds.

0-3 months Astoundingly, between 0-3 months babies learn to turn to you when you speak, and smile when they hear your voice. In fact, they seem to recognise your familiar voice, and will quieten at the sound of it if they are crying. Tiny babies under three months will also stop their activity and attend closely to the sound of an unfamiliar voice. They will often respond to comforting tones whether the voice is familiar or not.

4-6 months Then, some time between 4 to 6 months babies respond to the word "no". They are also responsive to changes in your tone of voice, and to sounds other than speech. For example, they can be fascinated by toys that make sounds, enjoy music and rhythm, and look in an interested or apprehensive way for the source of all sorts of new sounds such as the toaster, birdsong, the clip-clop of horses' hooves or the whirr of machines.

7-12 months The 7 to 12 months period is exciting and fun as the baby now obviously listens when spoken to, turns and looks at your face when called by name, and discovers the fun of games like: "round and round the garden", "peep-oh", "I see" and "pat-a-cake" (These simple games and finger plays will have regional names and variants). It is in this period that you realise that he or she recognises the names of familiar objects ("Daddy", "car", "eyes", "phone", "key") and begins to respond to requests ("Give it to Granny") and questions ("More juice?").

1-2 years Now your child points to pictures in a book when you name them, and can point to a few body parts when asked. He or she can also follow simple commands ("Push the bus!") and understand simple questions ("Where's the bunny?"). Your toddler now likes listening to simple stories and enjoys it when you sing songs or say rhymes. This is a stage in which they will want the same story, rhyme or game repeated many times.

2-3 years By now your toddler will understand two stage commands ("Get your socks and put them in the basket") and understand contrasting concepts or meanings like hot / cold, stop / go, in / on and nice / yuccy. He or she notices sounds like the telephone or doorbell ringing and may point or become excited, get you to answer, or attempt to answer themselves.

3-4 years Your three or four year old understands simple "Who?", "What?" and "Where?" questions, and can hear you when you call from another room. This is an age where hearing difficulties may become evident. If you are in doubt about your child's hearing, see a clinical audiologist.

4-5 years Children in this age range enjoy stories and can answer simple questions about them. He or she hears and understands nearly everything that is said to them at home or at pre-school or day care. Your child's ability to hear properly all the time should not be in doubt. If you are in doubt about your child's hearing, see a clinical audiologist. If you are in doubt about language comprehension, see a speech-language pathologist.


Expressive LanguageLearning to Speak, and to Use Language
Birth Newborn babies make sounds that let others know that they are experiencing pleasure or pain.

0-3 Months Your baby smiles at you when you come into view. He or she repeats the same sound a lot and "coos and goos" when content. Cries "differentiate". That means, the baby uses a different cry for different situations. For example, one cry says "I'm hungry" and another says "I have a pain".

4-6 months Gurgling sounds or "vocal play" occur while you are playing with your baby or when they are occupying themselves happily. Babbling really gets going in this age range, and your baby will sometimes sound as though he or she is "talking". This "speech-like" babbling includes many sounds including the bilabial (two lip) sounds "p", "b" and "m". The baby can tell you, using sounds or gestures that they want something, or want you to do something. They can make very "urgent" noises to prompt you into action.

7-12 months The sound of your baby's babbling changes. This is because it now includes more consonants, as well as long and short vowels. He or she uses speech or other sounds (i.e., other than crying) in order to get your attention and hold on to it. And your baby's first words (probably not spoken very clearly) have appeared! ("MaMa", "Doggie", "Night Night", "Bye Bye")

1-2 years Now your baby is accumulating more words as each month passes. he or she will even ask 2-word questions like "Where ball?" "What's that?" "More chippies?" "What that?", and combine two words in other ways to make the Stage 1 Sentence Types ("Birdie go", "No doggie", "More push"). Words are becoming clearer as more initial consonants are used in words.

2-3 years Your two or three year old's vocabulary is exploding! He or she seems to have a word for almost everything. Utterances are usually one, two or three words long and family members can usually understand them. Your toddler may ask for, or draw your attention to something by naming it ("Elephant") or one of its attributes ("Big!") or by commenting ("Wow!").

3-4 years Sentences are becoming longer as your child can combine four or more words. They talk about things that have happened away from home, and are interested in talking about pre-school, friends, outings and interesting experiences. Speech is usually fluent and clear and "other people" can understand what your child is saying most of the time. If stuttering occurs, see a speech-language pathologist. Stuttering is not a normal part of learning to talk, and neither is persistent hoarseness.

4-5 years Your child speaks clearly and fluently in an easy-to-listen-to voice. He or she can construct long and detailed sentences ("We went to the zoo but we had to come home early because Josie wasn't feeling well"). He or she can tell a long and involved story sticking to the topic, and using "adult-like" grammar. Most sounds are pronounced correctly, though he or she may be lisping as a four year old, or, at five, still have difficulty with "r", "v" and "th". Your child can communicate easily with familiar adults and with other children. They may tell fantastic "tall stories" and engage strangers in conversation when you are out together.

Zoo tracks children with Bluetooth tags

Denmark's Aalborg Zoo is setting up a system that lets parents use their cell phones to keep tabs on their children's whereabouts.
BodyTags, developed by tracking specialists BlueTags, are small Bluetooth pods that clip to a child's clothing. Base stations scattered around a site detect nearby tags and relay their location to a central database via wireless LAN (local area network). Parents register their mobile phones with the system and can get an update on their progeny's position within 20 seconds of sending a query text message.
The zoo will deploy the system--the first of its kind--in July, with 200 tags and 50 access points covering the zoo's grounds.
"We are very excited about the possibilities that the BlueTags tracking system provides and we are proud to be the first," said Henning Julin, director of Aalborg Zoo. "I expect many of my international colleagues to receive this tracking solution for children with open arms."
Peter Lund, vice president of business development at BlueTags, said, "The system will spot when a child is near an exit from the park, and can alert the parents, the administrators and the park's security." Lund admitted that there was nothing stopping mischievous children from removing or swapping their tags, but he said "the next version will be a wristband that can't be taken off without signaling an alarm." Not only can parents relax and enjoy the attraction more with this system in place, he said, but it gives children more opportunities to freely explore at their own pace.
Other features include an optional automatic SMS sent every time a child moves from zone to zone. "Both tag and access point can be adjusted in range," Lund said. "Entrance points can be accurate down to two to three meters, but larger zones can be set and can overlap to improve precision."
Lund said pricing for the tags would be set by the location's owners, and could factor in a per-SMS charge if appropriate. "The software in the system can track up to 100,000 tags, but the current hardware is limited to around 2,000. We're also looking at other sorts of places, such as airports and hospitals," Lund said.
BlueTag expects the first deployment of the system in the United Kingdom to take place before the end of 2003.
