Patent EP-0423887-A2 (EP)
Inventor: KNAPP ALAN GEORGE C O PHILIPS
IPC: G02F1/1368
Filed: 1990-10-12
Abstract: An active matrix display device comprises a row and column array of liquid crystal display elements (12) driven by switching and data signals supplied via row and column conductors (R and C) from driver circuits (30 and 32), with at least most display elements each being addressed through two TFTs (TA, TB) connected to different row conductors (R) for fault tolerance purposes. At their ends remote from the driver circuit (30) the row conductors (R) are each connected to a supplementary TFT (40) to which a predetermined potential, around the off level applied to TFTs TA and TB, is supplied, this TFT being periodically switched in operation. In the event of a row conductor discontinuity, switching of the TFT (40) prevents any charge build up on the broken section and ensures that the display element TFTs connected thereto are maintained sufficiently off. The supplementary TFTs 40 may be respectively switched by a switching signal supplied to an adjacent row conductor by the circuit (30) using an interconnection (42) or, alternatively the TFTs (40) may be switched simultaneously through a common gate line (43) in intervals between successive switching signals from the circuit (30).

Abstract: A machine tool for machining a workpiece (11), the workpiece (11) being fastened to a support (9) which has its bearings in a frame (1) of the machine tool and is rotatable about an axis of rotation (13), while a tool (37) is movable relative to the workpiece (11) by means of a positioning device (35) provided on a carrier (17) of the machine tool. The carrier (17) is movably guided relative to the support 
(9) along a straight guide (23, 25) of the frame (1) in a direction parallel to the axis of rotation (13) by means of static fluid bearings (19, 21), so that a space easily accessible to an operator is created between the carrier (17) and the support (9) through displacement of the carrier (17). The carrier (17) can be coupled to the frame (1) by means of coupling members (51) provided with bolts (75), a head of each bolt (75) forming a piston (73) which can be moved in a cylinder (59), which is hinged to the carrier (17). In the operational condition of the machine tool, in which the workpiece (11) is machined with the tool (37), each bolt (75) is subjected to a tensile stress which is achieved through the supply of pressurized fluid to the cylinders (59), so that a particularly rigid coupling of the carrier (17) to the frame (1) is obtained. In particular, so-called masters for projection television screens in the form of circular Fresnel lenses of a comparatively large diameter are manufactured with these machine tools.

Abstract: An object-oriented query language apparatus and method provides data abstraction, seamlessness with respect to the host programming language, set support orthogonal to persistence and strong typing. Such apparatus for processing queries includes a preprocessor (144,148) to parse, optimize, and translate object query language statements into efficient host language statements, connected to a compiler (152) that compiles such host language statements into executable code (154). Therefore, by inputting a program containing statements using a host language's type system as well as employing the host language's expressions, object composition, and inheritance in the formulation of queries, and by combining the Select-From-Where style of Standard Query Language as a basic structure for query statements with the set-valued function of the host language as targets for those queries, an associative query capability is added to a host programming language, thereby improving its versatility and functionality.

Abstract: The present off/on delay circuit operates within the power supply of a microcomputer system to interrupt transfer of regulated DC voltage to the system microcomputer and attachments in respect to indications of power disturbance and system switch status produced in the supply. Upon termination of such indications, this circuit selectively delays reappearance of regulated DC voltage to the level required for system operation so that whenever the microcomputer resets, the attachments must also reset; thereby preventing lockout impasses in the system rebooting process. The circuit operates in response to a plurality of DC voltage indications in the power supply, including at least an indication distinguishing the state of AC source power as either good or bad, and an indication distinguishing the state of a manually operable system power switch as either on or off. In one embodiment, the delay in reappearance of regulated DC operating voltage is chosen to be either relatively fast or slow depending upon how long the system operating voltage has been deactivated. Thus, the slow delay is chosen so as to effectively lengthen the effects of short duration outages or disturbances sufficiently to preclude lockout.

Abstract: Registration signal channel overloads occurring due to overly numerous autonomous registration messages initiated by the mobile radiotelephones are averted by monitoring the number of autonomous registrations occurring or requested in a particular local cellular system and responding in the event of an impending overload by sending messages to specified mobile radiotelephones instructing them not to register at this time. 
     In one implementation disclosed herein the roamer mobile radiotelephones requesting registration within an area covered by a cellular system facing an impending overload are instructed, via an overhead message, not to register. Allowance of registration is not permitted until the overload condition is terminated. In another implementation the period between autonomous registrations is increased until the overload is cleared.

Abstract: A railway vehicle set (1), for use for example as a car transporter, comprises minor length vehicles (3) provided between major length vehicles (2) and (4). The minor length vehicles have radiussed ends which are in closely spaced nested relationship with substantially correspondingly radiussed ends of the first vehicles. The arrangement has the advantage that, when the vehicle set travels around a curve, the angle between the centre lines of two of the adjacent major length vehicles is less than would be the case if the intermediate, minor length vehicles were not present. This enables cars to be positioned across the gaps between adjacent vehicles without fear that the articulation of the vehicles will interfere with the car body-work and result in damage thereto.
