Patent TW-I245933-B (TW)
Title: Switchable color filter
Inventor: FUENFSCHILLING JUERG
IPC: G02F1/1347
Filed: 2001-11-16
Granted: 2005-12-21
Abstract: The liquid crystal switchable color filter switches between three color bands and is preferably used for time-sequential color devices, as for example projection devices, direct view displays and video cameras. The color filter employs circularly polarizing selective reflection bands of at least four cholesteric filters (89, 91, 93, 95) together with three liquid crystal switches (81, 83, 85) and related retarder layers. Between the first and the second as well as between the third and the fourth cholesteric filter an additional half-wave plate (111, 113) is provided, which makes it possible to use cholesteric filters having all the same handedness. Furthermore, for the blocking state of a color band the optic axis of the corresponding liquid crystal switch is parallel or perpendicular to the polarization direction. This concept simplifies production and still exhibits excellent properties for the color switch. Moreover, it advantageously allows overlapping color transmission bands thus improving the light efficiency.

Title: Method for testing integrated circuits
Inventor: FELBER NORBERT
IPC: G01R31/317
Filed: 2001-12-20
Granted: 2004-02-21
Abstract: The method according to the present invention relates to the detection of fabrication defects in static CMOS circuits. An integrated circuit, for instance, having a gate (12, 13) additionally includes two sleep transistors (14, 15) and two pull transistors (16, 17) of regular threshold and low leakage. The sleep transistors are used to break up the gate into two parts (12; 13) for allowing a pair of response sequences. The two responses are either checked for consistency or compared against a predetermined expected response sequence. The usage of the pull transistors is as passive loads such as to enable pseudo NMOS and pseudo PMOS operation. One of the advantages of the method according to the invention, is that it is insensitive to MOSFET leakage currents.

Granted: 2004-11-21
Abstract: A method and apparatus for reducing the slot number used for external connection of the equipment is disclosed in the present invention. The invention is suitable for use in the electronic information equipment that includes at least one interface insertion slot apparatus for providing the user to use a transmission line to connect each peripheral apparatus so as to conduct the operation of data transmission. The insertion slot apparatus has more than two applications, which include the input terminal of transmission line of peripheral equipment and the input terminal of conduction wire of the externally added power source, such that no extra insertion slot is required for the externally added power source. Thus, the number of insertion slots of the equipment and the volume equipment itself can be reduced. One pin of the plug of externally added power source input terminal is set as the signal detection pin, which transmits signal to notify the user of bus controller at the position where the equipment is connected that external power source is used to supply electric power, such that it is unnecessary to perform power-saving mode of automatic power-off operation onto the equipment. In addition, the internal circuit of the connected equipment is used to separate the external power source from the internal power source of the equipment itself so as to cut-off the power supply path of the battery power source and perform power supply onto the equipment from the external power source. The interface insertion slot can be connected with the computer transmission line to input the required power source of the computer so as to reach the design purpose of using one slot for multiple applications and reducing the number of external insertion slots of the equipment.
