Patent EP-0433782-A2 (EP)
Inventor: PRESTTUN KARE
IPC: H04M9/02

Abstract: This invention relates to a telecommunication system including a conference information system including a number of participants each equipped with a separate node (2, 4, 8), which conference nodes may be interconnected via a switching network (1) such as a public switched telephone network, and where each participant node (2, 4 , 8) is including means for receiving a sum conference information signal from the other participating nodes, means for adding the signal generated in each conference node to the sum signal, and means for controlling the conferencing functions. 
     According to this invention all of the nodes (2, 4, 8) in the conference connection are interconnected in a complete conference ring (11) by means of one single connection (12) in which the information signals are transmitted from node to node in one single direction (arrow 12). 
     Some of the advantages of this system are
     a conference may be established even if the possibly centrally arranged exchange is not provided with a conference facility.   The conference facility is introduced by equipment distributed in each node terminal.   The line requirement is reduced to the half, but still the same traffic capacity may be handled by the system.   all the nodes now get identical status in the ring, and therefore all of the nodes may be designed as quite identical circuits.

Abstract: A novel method and system for operation in combination with a laser printer (10) for expanding its character and typeface selection capability. The sequence and operation for this method and system include dividing (Figure 2) a list of characters to be printed into a plurality of character groupings or collections (32, 34, 36), storing these character groupings or collections in a plurality of different memories or memory sites (28), and providing an input command signal (37) to these memories or memory sites which corresponds to a selected character desired to be printed. The different memories (Figure 1) or memory sites (28) are addressed starting first with the memory or memory site (32) storing the largest character grouping or collection having the most frequently used characters therein and then addressing the different memories or memory sites (34, 36) in sequence to or toward the memory or memory site (36) storing the smallest number of less-frequently used characters therein. In this manner, the memory storage capability and computational speed of the laser printer (10) are maximized, and the price/performance figure of merit and reliability of the printer (10) are also maximized.

Abstract: Apparatus for examining a test object (4) with gamma- or X-ray radiation, having a primary X-ray source for generating at least one primary X-ray pencil beam (3) directed onto the test object (4), and having at least one slit diaphragm (8, 9), which is arranged between the test object (4) and a detector (6, 7) and through which scattered X-ray radiation (26, 27, 28, 29) formed in the test object (4) by the primary X-ray radiation (3) (Compton effect) is directed onto at least one detector (6, 7). The range of depth of the test object that can be covered by the detectors can be changed without changing the position of the test object or of the examining instrument due to the fact that the position of the slit diaphragm (8, 9) can be changed in relation to the detector (6, 7) by means of an adjusting device (18, 19).

Abstract: In most cases, optical test methods are used for image analysis, especially for grading circuit board modules in electronics. Laser triangulation can be used for recording three-dimensional elevation images in digitised form. During the processing of the grey-scale image, three-dimensional data are derived from two-dimensional grey-scale images which reproduce the brightness distribution. Since three-dimensional image analysis by means of triangulation has significant advantages, the inspection of soldered joints is also to be carried out by means of this method. For this purpose, three-dimensional elevation images and two-dimensional grey-scale images of an object under test are simultaneously recorded in digitised form and plausibility checks are carried out between the two different types of image information items (in each case at corresponding locations). Thus, an information item which cannot be identified due to measuring errors in the three-dimensional elevation image can be replaced by the corresponding information items of the two-dimensional grey-scale image. <IMAGE>

Abstract: The present invention allows image recording with plural light beams while eliminating alignment changes of light spots on the inner face of a drum. A light beam output unit 212 combines two circularly polarized light beams having opposite handedness to each other to produce a composite light beam CB. A polarization beam splitter 203 and mirrors 205 and 207 change the course of the light beam towards the inner face of a drum 120. A quarter-wave plate 202 and the polarization beam splitter 203 splits the composite light beam to two separate light beams as a function of the handedness of the circularly polarized light. The optical elements 202, 203, 205, and 207 are integrally rotated around the axis of the drum 120 by a main scanning motor 230, thus scanning a photosensitive material 110 held on the inner face of the drum 120 with the light beams.

Abstract: There is disclosed a linear block copolymer comprising at least one triblock I-B-I, wherein I is a block of a polymerized conjugated diene of at least 5 carbon atoms, such as isoprene, and B is a block of a polymer of a conjugated diene, different from that of formula (1), of at least 4 carbon atoms, such as 1,3-butadiene. The B block is selectively hydrogenated, while each of the I blocks retains a sufficient amount of its original unsaturation to vulcanize the copolymer. There is also disclosed an alternative linear block copolymer containing at least one triblock of the first polymer block made from an aryl-substituted olefin, such as styrene, and the conjugated diene used to polymerize the block I, the second middle polymer block of the diene used to polymerize the block B, and the third polymer block which is the same as the first polymer block. In this alternative copolymer, the middle block is also selectively hydrogenated, thereby leaving the terminal polymer blocks with a sufficient amount of double bonds to vulcanize the copolymer. The polymers can be crosslinked or functionalized through the terminal blocks containing the vinyl unsaturation. There are also disclosed random and star-branched block and random copolymers made from the same monomers as the linear block copolymers. 
     Also disclosed are methods of producing and selectively hydrogenating the polymers.

Abstract: A cartridge ribbon (2) for impact printing contains an endless ribbon (4) initially carrying ink having dye as its only coloring matter. The initial dye is in heavy enough quantity to permit infrared readability of bar codes printed by the ribbon (4). Re-inking reservoir (16) transfers ink through drive gear (10) only to the track (28) which is impacted during printing. The ink in the reservoir (16) is colored with carbon black. Bar code functioning is maintained by the carbon black added by re-inking. This limited presence of carbon black does not hamper ribbon (4) feed unacceptably, while a ribbon (4) with a full carbon-black ink would not feed well.

Abstract: A test apparatus and method is disclosed for determining the absolute noise figure of an optical amplifier. The apparatus comprises an optical receiver (22) and functions to measure the output power of a test noise source (12), such as a lamp or LED. A plot of input power versus output power yields a linear relationship, with a y-intercept at the test apparatus (first) noise floor (No). An optical amplifier (40) to be tested is then inserted in the signal path between the noise source and the receiver. A new plot is generated and a second system noise floor value is determined (N 1 ). The difference between the two noise floor values (N 1  - No) is then defined as the amplifier absolute noise figure (N A ). The inventive technique is equally applicable to semiconductor and fiber optical amplifiers.
