Abstract: A display may include an array of pixels such as light-emitting diode pixels. The pixels may include multiple circuitry decks that each include one or more circuit components such as transistors, capacitors, and/or resistors. The circuitry decks may be vertically stacked. Each circuitry deck may include a planarization layer formed from a siloxane material that conforms to underlying components and provides a planar upper surface. In this way, circuitry components may be vertically stacked to mitigate the size of each pixel footprint. The circuitry components may include capacitors that include both a high-k dielectric layer and a low-k dielectric layer. The display pixel may include a via with a width of less than 1 micron.

Abstract: A semiconductor device includes first nanostructures vertically separated from one another, a first gate structure wrapping around each of the first nanostructures, and second nanostructures vertically separated from one another. The semiconductor device also includes a second gate structure wrapping around the second nanostructures, a first drain/source structure coupled to a first end of the first nanostructures, a second drain/source structure coupled to both of a second end of the first nanostructures and a first end of the second nanostructures, and a third drain/source structure coupled to a second end of the second nanostructures. The first drain/source structure has a first doping type, the second and third drain/source structures have a second doping type, and the first doping type is opposite to the second doping type.

Abstract: A method for configuring an interface device and a protection device in a digital communication system. The interface device has a first port for communicating with other devices, the first port being in a high-impedance state when the interface device fails. The protection device has a second port for replacing the communication of the interface device when the interface device fails, the second port being in a high-impedance state when the protection device is not in the replacing state. The primary winding of a first transformer is in series connection with the first port, and the primary winding of a second transformer is in series connection with the second port. The secondary winding of the first transformer and the secondary winding of the second transformer are connected in parallel. The resultant configuration makes the system simplified, compact, economic and easy for maintenance.

Abstract: A method of failure protection in a digital transmission system having a plurality of transmission elements connected in a ring configuration over metallic media, said ring configuration being formed by at least two paths, one path as a normal path for the transmission at the normal status, another path as a backup path which forms a closed loop and has no connection with said normal path at the normal status, said normal path and said backup path having opposite transmission directions, said method comprising the step of connecting said normal path and said backup path in said transmission element through hardware when a failure happens in said normal path so as to maintain the transmission. A digital transmission system with less expensive transmission elements and better failure protection can be obtained accordingly.

Abstract: A process for preparing an optically active (S)-&agr;-aryl propionic acid, by hydrolyzing a racemic thioester of &agr;-aryl propionic acid at various temperature in different aqueous organic solvents in the presence of an (S)-stereoselective lipase to form an (S)-&agr;-aryl propionic acid product, while the unreacted (R)-thioester of &agr;-aryl propionic acid can be converted to the corresponding (S)-thioester of &agr;-aryl propionic acid via a racemization reaction by adding a base as the catalyst in the solution and then hydrolyzing by the lipase described as above so that the (S)-&agr;-aryl propionic acid can be obtained theoretically at a conversion of 100% and with high optical purity.
