Abstract: One aspect of the invention is a bistable cholesteric writing tablet on which an image is formed by applying a suitable voltage while applying writing pressure, which results in a focal conic texture in a reduced gap region of the active layer while not changing the texture of the unreduced gap region of the active layer (e.g., a written portion being in a focal conic texture on a background in the planar texture). Another aspect of the invention is a multi-color stacked writing tablet in which a color of an image is selected by applying a suitable voltage while applying writing pressure using an instrument such as an untethered stylus on the surface of the tablet. The writing tablet includes at least two or three stacked layers of bistable cholesteric liquid crystal material. Selected colors can be additively mixed to achieve intermediate colors as desired. The image can be erased and new images written on the tablet.
Abstract: A color wheel is provided with a balancing device. The balancing device encompasses an essentially circular track whose center point coincides with the axial center of rotation of the color wheel. The track is provided with at least two mutually independent, movable balancing weights. Moving the balancing weights along the track requires a force greater than the gravitational force of the balancing weight. To balance a color wheel, a determination is made of a position in which a balancing weight corresponding to the total weight of the balancing weight system would have to be placed in order to balance the color wheel. At least one of the balancing weights is then moved to the position, according to the determination, where one of the balancing weights corresponding to the total weight of the balancing weight system would have to be placed.

Abstract: Magnetic element with thermally-assisted magnetic-field writing or thermally-assisted spin-transfer writing, comprising: a reference magnetic layer having a fixed direction magnetization; a storage magnetic layer exchange-pinned with an antiferromagnetic layer, wherein the magnetization direction of the storage layer can vary when said element can be heated to a temperature at least higher than a critical temperature of the antiferromagnetic layer; a tunnel barrier, provided between the reference layer and the storage layer; wherein the magnetic reference layer, and/or the magnetic storage layer includes at least one electrically-resistive thin layer for heating the magnetic element. The magnetic element disclosed herein has a voltage gain of typically 10 to 50% compared to conventional magnetic elements and shows a reduction of the stress induced during a writing operation as well as a reduction of the aging.

Abstract: A method of measuring server performance includes recording a time of queuing a request by a client for primary resources managed by the server; recording an estimated wait time for responding to the request for primary resources; recording a time of service for the request for primary resources; and calculating a punctuality metric of the request for primary resources by subtracting the difference between the time of service and the time of queuing from the estimated wait time. The punctuality metric is representative of the performance of the server.
Abstract: The present disclosure concerns a magnetic random access memory-based ternary content addressable memory cell, comprising a first and second magnetic tunnel junction respectively connected to a first and second straps extending on each side of the first and second magnetic tunnel junctions, respectively; a first and second selection transistors, respectively connected to one extremity of the first and second straps; a first and second current lines; and a conductive line electrically connecting in series the first and second magnetic tunnel junctions at their ends opposed to the ones connecting the first and second straps. The cell disclosed herein has smaller size and can be advantageously used in memory devices having a high cell density array.
Abstract: This interrupter device includes a parallel branch (4) in which a vacuum switch chamber is connected for breaking current. The branch is inactive in normal operation, with current flowing in it only when the disconnector (2) has started its opening movement, by progressive transfer of the current from the main power line (1) to the branch (4). Since the vacuum switch (6) is generally at rest, it no longer needs to be dimensioned to satisfy stringent electrical and dielectric requirements for normal operation.

Abstract: Structurally stable and mechanically strong ceramic oxide aerogels are provided. The aerogels are cross-linked via organic polymer chains that are attached to and extend from surface-bound functional groups provided or present over the internal surfaces of a mesoporous ceramic oxide particle network via appropriate chemical reactions. The functional groups can be hydroxyl groups, which are native to ceramic oxides, or they can be non-hydroxyl functional groups that can be decorated over the internal surfaces of the ceramic oxide network. Methods of preparing such mechanically strong ceramic oxide aerogels also are provided.
