Abstract: In this method, a transformer (1) is protected by means of differential protection, the current flowing in each case being detected by means of sensors both at the input (E) and at the output (A). In this connection, internal faults in the transformer (1) are to be rapidly detected and disconnected. This is achieved by the fact that, in addition, the voltage is detected both at the input (E) and at the output (A) and that the detected current and voltage values both at the input (E) and at the output (A) are in each case logically combined in a processor (18, 25), forming a fault direction signal. <IMAGE>

Abstract: A vertical semiconductor device having a plurality of vertical active regions and a method for manufacturing such a vertical semiconductor device. In the preferred embodiment, a vertical multicollector pnp transistor is formed by disposing a plurality of n type epitaxial layers (20, 30) over a bottom p type substrate (10). Each epitaxial layer (20, 30) has a plurality of collector regions (27, 28) formed therein. The collector regions are connected using a single diffusion step to form vertical collectors (67, 68) for the pnp transistor. The base (55) is formed from the epitaxial layer (30) and the emitter (35, 36) is formed using a separate implant or diffusion step. Vertical isolation regions (51, 61, 52, 62, 53, 63) are formed contemporaneously with the vertical collectors. The resulting pnp transistor has vertical collectors and isolation regions formed with less silicon, fewer diffusion steps, and more precise and reduced dimensions.

Abstract: A typical fibre-optical cable has a central support element, optical fibres stranded thereupon, a strength member, a core winding and a cable jacket. The cable is severed at a cable branch and the optical fibres are directly spliced or connected to one another via coupling elements. The technology to date is complicated, particularly when signals are to be coupled in or out only in a few optical fibres on a fibre-optical cable. A simplification results when the optical fibres are applied to the surface of the support element (1) in such a way that one or more optical fibres (2) can be removed from parts of the fibre-optical cable with a sufficient excess length when the fibre-optical cable is removed in the respective region to such an extent that the optical fibres are accessible. <IMAGE>

Abstract: A device and method of separating the cellular components of whole blood from plasma or serum and assaying the plasma or serum for a soluble constituent. The device includes a filter pad, that separates the cellular components of whole blood from the serum or plasma, in releasable contact with a test pad, that assays the serum or plasma for a particular soluble constituent. The filter pad, contaminated with the cellular components, is detachable from the plasma or serum-saturated test pad, thereby eliminating assay interference by the cellular components of whole blood. The method includes contacting the whole blood with a test device including a filter pad comprising a suitable carrier matrix optionally incorporating a lectin, a thrombin, or a mixture thereof, such that the cellular components of the whole blood are separated from the plasma or serum as the blood permeates through the filter pad. The essentially cell-free plasma or serum then saturates a test pad that is in releasable contact with the filter pad. After the plasma or serum saturates the test pad, the filter pad is detached from the test pad, and the exposed test pad is examined for a qualitative or quantitative response to a particular soluble constituent of the whole blood.

Abstract: A public key cryptographic system is disclosed with enhanced digital signature certification which authenticates the identity of the public key holder. A hierarchy of nested certifications and signatures are employed which indicate the authority and responsibility levels of the individual whose signature is being certifified. The certifier in constructing a certificate generates a special message that includes fields identifying the public key which is being certified, and the name of the certifee. The certificate is constructed by the certifier to define the authority which is being granted and which may relate to wide range of authorizations, delegation responsibilities or restrictions given to, or placed on the certifiee. Methodology is also disclosed by which multiple objects such as, for example, a cover letter, an associated enclosed letter, an associated graphics file, etc., are signed together. Methodology is also disclosed for digitally signing documents in which a digital signature is generated for both computer verification and for reverification if a document needs to be reconfirmed by reentering from a paper rendition.

Abstract: In a first embodiment a number of stent segments (30) are connected together by hinges (32) welded in place to provide articulation between the stent segments. The hinges can be, among other shapes, either a straight wire or a coiled wire of biocompatable material. A second embodiment uses a stent made up of a number of wires welded together for the stent segments with connection between adjacent stents provided by having one of the wires of adjacent stents continue between these adjacent stents to provide a hinge action. In this embodiment the wire portion extending between the segments may be ground to a smaller diameter than the wire of the stent segment itself, to provide the necessary hinge flexibility. This articulated stent, made up of a number of individual stent segments, gives support for curved arteries, with the hinges between the segments providing both articulation and spacing between the stent segments. This articulated stent is tailored to match the curvature existing in the artery and is positioned at the site with the necessary preferred angular orientation using a known catheter system.

Abstract: Apparatus is provided for reproducing either M channels of digital audio signal recorded in longitudinal tracks on a record medium or an analogue audio signal recorded in one or two stereo tracks. M heads (1A...) are used to reproduce the M channels of digital audio signals and N of those heads (1A...) (N < M) are used to reproduce the analogue audio signal. The reproduced digital or analogue audio signals are multiplexed (3) and digitized (4). When digital audio signals are reproduced, the digitized multiplexed signals are digitally processed and then converted (16) to analogue form. When analogue audio signals are reproduced, the digitized multiplexed signals are summed such that signals reproduced by the N heads (1A) are combined to form a digital representation of the recorded analogue audio signal. The summed signals then are converted (16) to analogue form to recover the original analogue audio signal.

Abstract: The position and orientation of the mobile sensor (4) are determined by the computing means (1) as a function of the coupling coefficients measured between each of the windings of the sensor and each of the windings of the transmitter (3). These measurements are marred by errors due to the imperfections in the gain of the various elements of the transmission and reception channels: inaccuracies, non-linearities, drifts. In order to eliminate these errors, a fixed sensor (8) is used whose coupling coefficients with the windings of the transmitter are measured in order to serve as a reference for correcting the coupling coefficients between the windings of the transmitter and of the mobile sensor.

Abstract: The construction elements each consist of a central section (10) and two outer sections (20, 30). The central section (10) has six straight, plane surfaces, two parallel, relatively long walls (11) and four walls (13, 14, 15, 16) which intersect one another in pairs at right angles by means of extensions. The outer sections (20, 30) are of cylindrical design and the segment of the cylindrical wall (22, 32) which lies against the central section (10) intersects the four walls (13, 14, 15, 16) so that a concave recess is formed there. The outer sections (20, 30) are half the height of the central section (10). Thus, these elements can be placed together in a row with the outer sections (20, 30) overlapping one another so as to form a carriageway border which can readily be altered or removed at any time without the elements being lost in the process.
