Abstract: Electronic Ink is new display device offering excellent resolution and high contrast under a wide range of viewing angles, requiring no external power to retain its image. However, designing electronic ink display device always posts a challenge to achieve high resolutions, flexible functionality, and low cost manufacturability. Since the number of controls to each individual pixel on a display increases with resolutions and display's functions, the display design becomes more complicated and drives to higher manufacture cost. Here, we propose to apply the threshold property of the electronic ink in response to applied electrical fields to design simplified displays with good resolutions, flexible functionality, and low cost manufacturability.

Abstract: A device for stabilizing the rotating speed of a record player has a passive element fitted on the same shaft of a rotating, disk, which activates a record to rotate together. The passive element is formed with a surface expanding outward from a center portion fitted with a shaft and having its outer annular portion engraved with annular minute net holes. A sensor facing the positions of the net holes is provided under a printed circuit board for detecting the change of the shifting speed of the net holes. The signal data detected by the sensor is fed to a micro-processor to carry on operation, and after that, the value of the signal data is transmitted back and automatically modulates the voltage supplied to the rotating disk to let the rotating disk and the record rotate steadily.

The outer pot body is provided with plural support members and a socket on its bottom base having a. micro-switch fixed under to connect the socket. The socket has two notches and an inserting groove on top and a sliding cover inside, a ring electric-heating tube fixed at the bottom of the inner pot, having two thirds embedded therein and two pins protruding at two opposite ends, with an actuating rod longer then the pins fixed between. Thus, when the inner pot is placed in the outer pot body, the actuating rod pushes the sliding cover to move away to let the actuating rod and the pins respectively inserting in the inserting grooves and the notches, synchronously with the bottom of the inner pot pressing the lug of the micro-switch to turn on power.

Abstract: A performance monitoring system for an all-optical network utilizes a multi-port optical switch and measuring instruments, such as an optical spectrum analyzer and a combination of a tunable optical filter and a quality factor calculator, to provide various signal quality parameters for each optical channel in the network. Quality factor calculations for the optical channels are based upon probability density distribution parameters. Performance monitoring is conducted for an all-optical network during normal operations without having to disconnect any of the optical components from the network.

Abstract: An anti-dust cover driving device for a CD player includes a base body, a laser head base unit mounted on the base body and having a laser head. An anti-dust cover is provided above the base body, moved to hide the laser head or not by a driving device consisting of a gear, a shaft, an activating means, and a power device for rotating the gear and the shaft. The anti-dust cover does not hide the laser head when a CD player cover is closed, but is moved to hide the laser head when the CD player cover is opened by means of the driving device. Therefore, the laser head is always hidden and prevented from having dust fall on it whether the CD player is closed or opened. And the anti-dust cover is moved within a short distance, not moving out of the dimensions of the CD player.
