Before the technical, some general information. E-ink display are found in a lot of e-readers, some mobile phones and similar devices and the intent is to provide a reading experience closer to that of ink on paper than conventional LCD displays deliver. E-ink screens are not backlit and require light falling on them in the same was as reading a book does; reducing eye strain during long reading sessions. An e-ink page is also persistent (does not need power to maintain the text) and power is only required for changing text on the page. The persistent nature of the pages leads to longer times between charging.

Estimating maximum demand is a topic frequently discussed. Working out how much power to allow for a building can be very subjective . Allowing too much power results in additional equipment, increased space requirements, greater system losses and extra cost. On the other side, no enough power results in operational problems. Trying to find the right amount of power is like gazing into a crystal ball and everyone will see something different.

These lifts were first built in 1884 by J. E. Hall and called a paternoster ("Our Father", the first two words of the Lord's Prayer in Latin) due to its resemblance of a loop of rosary beads. The are not built anymore, apparently due to safety concerns (have to say I was always slightly worried about somehow becoming squashed).

GE's latest thinking on product manufacturing is he Shingijutsu philosophy or Lean production system. They have started applying this at the Louisville Appliance Park manufacturing facility. The first application of the system is for GE's GeoSrping hybrid water heater for which they plan to transfer manufacturing from China to Louisville.

Three phase systems are derived from three separate windings, either connected in delta or star (wye). Each winding can be treated separately, leading to the idea that the load in each winding can be viewed independently. I'm not going into any math's, but if you did you can prove this.

The mobile phone was born in 1973. They were the size of a brick and weighed a couple of kg, making them difficult to fit into your pocket. At a few thousand pounds each not may could afford them. Battery life was around 20 minutes, which was probably good given the weight of the phone.

The inventor of the first visible light-emitting diode makes history again this year as it begins to show customers a 40-watt replacement GE Energy Smart® LED bulb available later this year or early 2011. GE Lighting's new LED bulb is expected to consume just 9 watts, provide a 77 percent energy savings and produce nearly the same light output as a 40-watt incandescent bulb, while lasting more than 25 times as long.
