Abstract: L'invention concerne un modèle (1) de surface variable sur le plan optique, comprenant au moins une représentation d'une configuration graphique. Des portions (3, 4, 5) de surface d'un type déterminé sont associées à chaque représentation. Lorsqu'on illumine ces représentations à l'aide d'une lumière visible, celles-ci sont visibles sous la forme d'images comprenant des points comparativement clairs et sombres, au niveau de différentes directions de vision. Les portions (3, 4) de surface associées aux points clairs d'au moins une des représentations présentent des structures de réseau possédant un nombre de lignes inférieur à 250 lignes par millimètres, de sorte que plusieurs ordres de diffraction se produisent dans la gamme visible. Les formes du profil des structures de réseau sont choisies de façon à ce qu'une proportion maximum possible de la lumière diffractée le soit dans des ordres de diffraction supérieurs, ce qui permet que la représentation correspondante apparaisse de manière achromatique. En outre, afin que le rapport entre la lumière diffractée dans des ordres de diffraction positifs et celle diffractée dans des ordres de diffraction négatifs soit le plus élevé possible, on utilise des structures de réseau présentant une forme de profil asymétrique et notamment une forme en dents de scie.

Title: Method for controlling non-volatile semiconductor memory system
Inventor: KAWAMOTO KAZUYA
IPC: G11C11/00
Filed: 1998-08-07
Granted: 2002-01-01
Abstract: In a memory system using a storage medium, which is inserted into an electronic apparatus via a connector to add a memory function thereto, the storage medium has a GROUND terminal, a power supply terminal, a control terminal and a data input/output terminal, and the connector has a function of being sequentially connected to each of the terminals. When the storage medium is inserted into the connector, the GROUND terminal and control terminal of the storage medium are connected to corresponding terminals of the connector before the power supply terminal and data input/output terminal of the storage medium are connected to corresponding terminals of the connector. Thus, it is possible to improve the stability when a memory card is inserted into or ejected from the memory system.

Abstract: A intermediate range/short range laser defense system (10) for use against chemical and biological submunitions (36). The system includes a source (12) of a high power laser beam (14) which is directed by a beam steering device (16). The beam steering device (16) is controlled by a processor (20) which generates control signals (22) for orienting the beam steering device (16) to the control the laser beam (18). The processor (20) operates in a LACROSST mode which enables detection of the submunitions (36). The processor (20) receives tracking information from a detector (26) and tracker (24). The processor directs the laser beam ( 18) towards a centroid (40) of a dispersion pattern or cloud (38). The laser beam (18) is then directed in an outward, spiral path (42) from centroid (40). When the laser beam (18) encounters a submunition (36), the laser beam locks onto the submunition (36) in order to heat the submunition (36), thereby denaturing or destroying the submunition (36).

Abstract: A method and apparatus for providing a soft finish on a fabric such as a suede tone, raised loops, broken loops or fleeced and for providing a faded effect such as a washed or faded denim. A fillet having a plurality of wires extending therefrom is wound on a cylinder of a finishing machine. The outer ends of the wires extending from the fillet are angled at approximately 80° from vertical. The wires are covered with an abrasive coating which is applied by an arc spray system. The coating extends around the perimeter of the wire from at least just below the bend of the wires and extending to the outer tip of the wires. The fabric is driven over a nip roll that is adjusted to bring the fabric in closer contact with the wires on the cylinder which is rotating.      An alternative embodiment of accomplishing the same type of soft finish such as suede or washed or faded denim finish is accomplished with multi rolls (or kiss rolls) finish machinery using the coated wire fillet on each roll. The wires of fillets for napping machines are similarly covered with the abrasive coating for achieving a more efficient operation on a napper finishing machine.

Abstract: Lampholders to be used with cold cathode fluorescent lamps of the type that do not require heated internal filaments. A lamp pin contact to engage one of the two pins at each end of the lamp provides the electrical circuit between a high voltage ballast and the gas within the lamp. A lamp retainer device engages the surface of the lamp envelope and cooperates with one lamp pin contact to support the lamp. The device may take the form of one or more cantilever mounted insulating or conductive arms, a flat or spring wire form or may be made of compressible material. A further form of lampholder uses a spring loaded contact to engage the contact pins of a fluorescent lamp and to make contact with a single power conductor.

Abstract: This invention is a medical device and a method of using it. The device is a foldable stent or stent- graft which may be delivered with (or on) a catheter or via surgical or other suitable techniques. The device is then expanded or unfolded. The expandable stent structure preferably utilizes at least one torsional member generally aligned with the longitudinal axis of the stent. The stent preferably has an undulating shape It may be helically deployed to form the generally cylindrical shape eventually deployed as the stent or it may be formed of one or more rings. The structure desirably is aligned to allow those undulating shapes in adjacent rings or turns of the helix to be in phase. The adjacent undulating shapes may be held in that phased relationship using a flexible linkage, often made of a polymeric material. The stent's configuration allows it to be folded or otherwise compressed to a very small diameter prior to deployment without changing the length of the stent. The stent is self-expanding, kink- resistant, easily bent along its longitudinal axis, does not change its length during that expansion, and is able to provide collapsible support for otherwise frangible graft material. The graft component cooperating with the stent is tubular and may be a biocompatible polymeric or collagenous material or combinations of the two which may, if desired, be reinforced with fibers. The invention involves procedures for deploying stem s or stent-grafts which have been folded, bound, or otherwise collapsed to significantly smaller diameters for insertion into a human or animal body. The deployment procedures may involve the use of an outer sleeve to maintain the stent or stent-graft at a reduced diameter or may involve a "slip-line" to hold and then to release the device.

Abstract: A telephone technician's remote assist apparatus connects into a telephone line to be tested by the technician from a remote location. Control signals are sent from the remote location to the remote assist apparatus over the same pair of wires of the telephone line under test. A particular control signal encoding includes two consecutive leading star (**) dual-tone multi-frequency tones. The remote assist apparatus opens the telephone line in response to at least one control signal, and the apparatus preferably automatically restores the line after a predetermined time so that the subscriber is not left disconnected. The particular control signal encoding and the automatic restoring features can be implemented without using the same pair of wires under test. Thus a method for use in testing a telephone line can include controlling by using the same pair of wires under test, but a method can also include using the particular type of encoded control signal and/or the automatic restoring features without using the same pair of wires under test.
