The weekly report summarizes progress of the Engineering Team working on a vacuum bottle product design. They discussed functions like including three temperature levels indicated by LED lights and a short circuit protection system. The team analyzed strengths like the easy to use vacuum bottle, and weaknesses like lacking some data and insufficient discussion with ID students. Their next steps are to calculate the circuit and consult more within the group.

Weekly Progress
On Thursday 22 Mar 2012 We’re met ID student talk about in the process of the companee. In
the morning dispute the function to require of the vacuum bottle. Someone think about
temperature it have three level is sixty degree eighty-five degree and onehundred degree. And
then have LED RGB for indicate temperature in the vacuum bottle and indicate mode of work. And
short circuit system.
Engineering knowledge
A light-emitting diode (LED) is a semiconductor light source. LEDs are used as indicator lamps in
many devices and are increasingly used for other lighting. Introduced as a practical electronic
component early LEDs emitted low-intensity red light, but modern versions are available across the
visible, ultraviolet, and infrared wavelengths, with very high brightness.When a light-emitting
diode is forward-biased (switched on), electrons are able to recombine with electron holes within
the device, releasing energy in the form of photons. This effect is called electroluminescence and
the color of the light (corresponding to the energy of the photon) is determined by the energy gap
of the semiconductor. LEDs are often small in area (less than 1 mm2).
Engineering Analysis
Strong Point
- The vacuum bottle have function easy to apply.
Week Point
- We are find a few the data cause have skill less.
- ID student a few talk about working process.
Next Week Job
- Calculate the circuit and consult in my group.
