Title: Method for coding an analog signal having a repetitive nature and a device for coding by said method
Inventor: VAN DER KROGT ADRIANUS ALPHONS
IPC: G10L19/08
Filed: 1991-09-09
Granted: 1996-05-21
Abstract: Method and device for coding a signal segment of a sampled analog signal having a repetitive nature according to the principle of long-term prediction (LTP), in which an accuracy is achieved in the coding which is comparable to that of high-resolution LTP          (HLTP) without the complexity appreciably increasing with respect to that of LTP. According to the method, after determining the number of samples D between the beginning of the segment to be coded and the beginning of the most similar segment determined according to the LTP principle, the number of samples in the segment to be coded is increased by a predetermined factor Ob by always placing (Ob - 1) samples having a value equal to 0 between two consecutive samples, and the number of samples in the preceding segment is also increased by the factor Ob; in the preceding segment, partial segments Cd are determined for which it is the case that the number of samples Dd, expressed in the numbers of samples after oversampling, between the initial time instant of the segment to be coded and the initial time instant of a partial segment Cd fulfils:          Dd = (D * Ob)/d, in which d = 1, 2, 3, 4 ...n, where n is a positive integer and where Ob and n are chosen in a manner such that Dd is always an integer, after which, in the segments Cd, the sample values are determined, by means of an interpolation technique, at predetermined positions which are situated at a spacing Dd from the original samples in the segment to be coded; of the segments Cd, that segment Cd is chosen as the most similar segment which has a correlation value Rd with the samples of the segment to be coded for which it is the case that Rd  q * Rmax, where q < 1 and Rmax is the maximum correlation value which has been found in correlating the segments Cd and the segment to be coded, and is that segment which yields the smallest associated value of Dd.

Title: Speed match ductor assembly
Inventor: GUARALDI GLENN A
IPC: B41F31/30
Filed: 1991-09-16
Granted: 1994-07-26
Abstract: In a printing press, a ductor assembly for transferring ink from a slowly rotating fountain roll to a rapidly rotating ink receiving roll includes a carriage and first and second idler rolls supported in counterrotating engagement on the carriage.  In one embodiment, the ductor assembly moves between a first position in which the first idler roll contacts and picks up ink from the fountain roll, and a second position in which the second idler roll contacts and transfers ink to the ink receiving roll.  The ductor assembly is driven to rotate at a speed intermediate the speeds of the fountain roll and the ink receiving roll, in a direction the same as the direction of rotation of the second idler roll about its own axis, and opposite to the direction of rotation of the first idler roll about its axis.  When the ductor assembly moves to the second position, the surface of the second idler roll which contacts the ink receiving roll is moving in the same direction as the surface of the ink receiving roll, and is moving with a speed about equal to the speed of the ink receiving roll.  This minimizes speed mismatch.  In another embodiment, the rotating ductor assembly is fixed in position and the ink receiving roll moves into and out of contact with the ductor assembly.

Title: Processing waste materials for anaerobic digestion of the biogenic-organic constituents of the garbage, particularly of the source separated organic waste, the non-recycable fraction of the domestic waste, the residual waste and the commercial wastes
Inventor: WILJAN HARRY
IPC: C05F9/02
Filed: 1992-03-23
Granted: 1995-06-20
Abstract: In a process of treating waste materials  for an anaerobic digestion of the biogenic organic constituents of the garbage, particularly of the source separated organic waste, the non-recycable fraction of the domestic waste, the residual waste and the commercial wastes, an easily dewaterable suspension of the biogenic organic substances is formed in a pretreating stage by a mechanical treatment including a selective dissolution and defibration of the biogenic organic substances. In dependence on the adjusted solids concentration the action of flow-dynamical forces  is  so  controlled  that  the  not  biogenic  organic substances, are not subjected to an appreciable disintegration before they are removed at the end of the pretreatment. Non-digestable substances are removed. The suspension is converted to biogas by an anaerobic digestion and to a compost-like residue. In the apparatus in accordance with the invention a gentle treatment of adhering solids in the crude waste is ensured in the pretreating stage in that the speed of the impeller 14 in the pulping vessel 13 is controlled in dependence on the solids concentration. This will also result in a distinct saving of energy and in a high efficiency.

Title: Insertion and tunneling tool for a subcutaneous wire patch electrode
Inventor: DAHL ROGER W
IPC: A61N1/05
Filed: 1992-06-04
Granted: 1998-09-15
Abstract: A tool  for subcutaneously  implanting a subcutaneous electrode comprising several wire patch electrode segments by way of a single surgical incision.   The tunneling tool comprises a stylet and a peel-away sheath.  The tunneling tool is inserted into an incision,  in a direction which corresponds to the desired placement of an electrode segment.  Once the tunneling tool reaches a desired position, the stylet is withdrawn, thereby revealing the interior of the peel-away sheath and a resulting subcutaneous tunnel.  The corresponding electrode segment is then inserted into this  subcutaneous  tunnel,  and  subsequently  implanted  in  the patient.  The implantation procedure is then repeated as many times as is necessary, using the same incision, until all the electrode segments  for the particular electrode configuration have been implanted.   In addition, the tunneling tool can be adapted to conform to varying electrode segment sizes, which thereby allows the tool to conform to the varying needs of each individual patient.  As an even further feature, the tunneling tool can be constructed in a curved configuration to facilitate electrode implantation in the lateral thoracic region of the body.

Title: Light source unit and optical head equipped therewith
Inventor: OGATA NOBUO
IPC: G11B7/1353
Filed: 1993-02-09
Granted: 1996-03-19
Abstract: A diffraction element is positionally adjusted on a calibrating optical head arrangement while an objective lens is positionally adjusted so as to maximize a total signal   calculated   in   a   photodetector,   whereby  a predetermined focusing error signal and tracking error signal are obtained. The thus adjusted diffraction element is adhesively secured on a package housing a light source and a photodetector to form a light source unit.  The thus prepared light source unit is positioned on and assembled into an optical head by angularly adjusting the light source unit and an objective lens on the optical head individually so that both the optical axis of the light emitted  from the  light  source unit  to  incident  on  a recording medium and the axis of the objective lens are aligned normal to the recording medium and by aligning the optical axis of the objective lens with the center of intensity  distribution  of  the  incident  light  on  the objective  lens.     This  configuration  eliminates  the necessity of mechanical parts  in the optical head for adjusting the diffraction element and the necessity of a space for the adjustment, so that it is possible to promote a small and light weight optical head.   In addition, by effecting the optical adjustment when the light source unit is assembled into the optical head, error signals can be adjusted.  Therefore, the adjustment step can be omitted.

Abstract: Automatic rain gauges (P00-POn) are disposed in the land area (ZT). A meteorological radar (R1) supplies, at a given radar periodicity, a radar image showing rainfall cells affecting the land area. By analysis of the series of radar images, the principal rainfall cells are dynamically monitored with regard to their shape and their movement. Then, a radar rain map is established, by cumulation in each pixel of the land area, of the precipitations due, during a second chosen interval of time, to these principal rainfall cells, with interpolation of their shapes and positions. There is selected at least one sub-system (PA, PB) of four rain gauges, separated from each other by about 2 to 4 kilometres and touched by at least one principal rainfall cell. Finally, the rain map is corrected at least partially as a function of the relationship between the cumulated real rain gauge data and the data of the said map at the locations of the rain gauges of the sub-system. This allows an excellent estimation of precipitations in each square kilometre of the land area. <IMAGE>
