Title: Method and device for improving the voltage quality of a secondary supply unit
Inventor: WEINHOLD MICHAEL
IPC: H02J3/18
Filed: 1998-08-17
Abstract: The invention relates to a method and a device for improving the quality of voltage of a secondary supply unit (16) by means of a compensation device (2) with a pulsed converter (4). Said pulsed converter is serial-linked into a transmission line (12) by means of a coupling transformer (10). According to the invention, positive- and negative-sequence deviations (uD,1~) are determined and are used to produce a basic transmission ratio space vector (üb). This space vector (b) is then used to generate control signals (S) for the pulsed converter (4), using the intermediate circuit voltage (Vdc) of said pulsed converter (4), so that a compensator voltage (uK) can be serial-linked into the transmission line (12). The invention hereby provides a means of generating a supply voltage (uN) of an ideal supply system (14) from a distorted supply voltage (uN) for a secondary supply unit (16).

Abstract: An overload relay includes a base (22) with electrical contacts (162, 164) thereon. A lever (116) including a contact actuator (140) is in proximity to the contacts (162, 164) and a pivot (122) mounts the lever (116) on the base (22) for pivotal movement between first and second positions. A releasable latch (106) normally holds the lever (116) in a particular one of the positions and a spring (144) is interposed between the base (22) and the lever (116) at a location spaced from the pivot (122) to bias the lever (116) toward the other of the positions by applying a bias thereto in a generally predetermined direction. The direction and location are such that when the lever (116) is in a latched position, the bias will provide a relatively small force tending to move the lever (116) toward the unlatched position and further is such that as the lever (116) moves towards the first position, the bias produces an increasing force tending to move the lever (116) towards the unlatched position.

Inventor: JEONG DEOG-KYOON
IPC: G06F3/14
Filed: 1999-09-10
Abstract: A new scheme to transfer bidirectional data streams between a digital display and a computer is disclosed. This bidirectional data transfer can make several I/O devices attach to a display. Existing digital display interfaces are usually unidirectional from a computing to a display. Due to the nature of the existing clocking scheme, backward data transfer from the display side to the computer requires a backward clock. This invention discloses a scheme to send data bidirectionally without sending the additional backward clock. This invention also discloses a scheme to tolerate jitters from the clock source. With this approach, this new interface can make a digital display an I/O concentrator.
