Beyond - Collapsible Input Device for 3D Direct Manipulation  view

What would it be like to reach into a screen and manipulate virtual objects as in real world. We present Beyond, a novel collapsible input device for direct 3D manipulation. When pressed against a screen, Beyond collapses in the physical world and extends into the digital space of the screen, such that users can have an illusion that they are inserting the tool into the virtual space. Beyond allows users to directly interact with 3D media, avoiding inconsistencies of input and output without having to wear special glasses. Users can select, draw, and sculpt in 3D virtual space and seam- lessly transition between 2D and 3D manipulation. We de- scribe detailed interaction techniques, implementation and application scenarios focused on geometric design and pro- totyping.

1960 - Metal Oxide Semiconductor (MOS) Transistor Demonstrated
John Atalla and Dawon Kahng fabricate working transistors and demonstrate the first successful MOS field-effect amplifier.

In 1959 M. M. (John) Atalla and Dawon Kahng at Bell Labs achieved the first successful insulated-gate field-effect transistor (FET), which had been long anticipated by Lilienfeld, Heil, Shockley and others (1926 Milestone) by overcoming the "surface states" that blocked electric fields from penetrating into the semiconductor material. Investigating thermally grown silicon-dioxide layers, they found these states could be markedly reduced at the interface between the silicon and its oxide in a sandwich comprising layers of metal (M - gate), oxide (O - insulation), and silicon (S – semiconductor) - thus the name MOSFET, popularly known as MOS. As their device was slow and addressed no pressing needs of the telephone system, it was not pursued further. In a 1961 memo, however, Kahng pointed out its potential "ease of fabrication and the possibility of application in integrated circuits." But researchers at Fairchild and RCA did recognize these advantages. In 1960 Karl Zaininger and Charles Meuller fabricated an MOS transistor at RCA and C.T. Sah of Fairchild built an MOS-controlled tetrode. Fred Heiman and Steven Hofstein followed in 1962 with an experimental 16-transistor integrated device at RCA.

The various electromagnetic based actuation(EMA) methods have been proposed for actuating microrobot. The advantage of EMA is that it can provide wireless driving to microrobot. In this reason a lot of researchers have been focusing on the EMA driven microrobot. This paper proposed a swimming microrobot driven by external alternating magnet field which is generated by two pairs of Helmholtz coils.

The microrobot has a fish-like shape and consists of a buoyant robot body, a permanent magnet, and a fin. The fin is directly linked to the permanent magnet and the magnet is swung by the alternating magnet field, which makes the propulsion and steering power of the robot. In this paper, firstly, we designed the locomotive mechanism of the microrobot boy EMA. Secondly, we set up the control system. Finally, we demonstrated the swimming robot and evaluated the performance of the microrobot by the experiments.
