Abstract: In an electronic cash implementing method, a user makes a bank apply a blind signature to user information Vi produced, by a one-way function, from secret information Si containing identification information, thereby obtaining signed user information. Further, the user makes the bank apply a blind signature to information containing authentication information Xi produced, by a one-way function, from random information Ri, thereby obtaining signed authentication information. The user (200) uses an information group containing the signed user information, the signed authentication information, the user information and the authentication information, as electronic cash for payment to a shop. The shop (300) verifies the validity of the signed user information and the signed authentication information, and produces and sends to the user an inquiry. In response to the inquiry the user produces a response Yi by using secret information and random information and sends it to the shop.

Abstract: Impact resistant and flame retardant polymer composition, slab-like rectangular solid made of said composition, and composite laminate article having at least one layer of said composition. Composition is preferentially compression molded using a blended particulate feed of relatively high bulk. The polymer composition comprises a maximum of 86 volume percent of ultra high molecular weight polyethylene (UHMWPE), a minimum of 8 volume percent of a flame retardant additive or mixture thereof, and a minimum of 6 volume percent of chopped reinforcing fibers, all volumes referring to the densified (molded) state. In addition the bulk volume of the chopped reinforcing fibers, as measured by a tapped density test, must be a minimum of 27 percent of the final molded volume of the composition (BVPF equal to or greater than 27). The maximum volume % loading of the additives is limited by the requirement that the notched Izod impact strength is a minimum of 7 ft.-lb per inch width. The preferred flame retardant additive is essentially a water insoluble form of ammonium polyphosphate having a water solubility not exceeding 1 gram per 100 grams of water, and the preferred reinforcing fibers are chopped glass fibers about 1/8 to 1/4" inch in length. A significant flame retardant improvement without sacrifice in impact strength is achieved if a thin compressible non-woven fiberglass veil is applied to the top of the particulate feed prior to molding the slab-like solid. The composite layer has first and third layers of essentially rigid compounded high molecular polymers above described, and a second or middle elastomer layer, which is also preferentially flame retarded.

Abstract: An infrared CCD sensor device by means of which picture elements of an IR scene are scanned in the line direction, charge signals are integrated, added in the correct phase and are read out in multiplex method, and which is composed of m detector elements in the column direction with m << n and n < 1, corresponding to many integration storage structures Ci1 ... Cin, allocated to the detector elements, so-called TDI CCD structures for charge displacement, each two adjacent line detector elements being allocated p CCD cells each and at least one CCD multiplexer structure for reading out the signal. This arrangement is to be improved in such a manner that, using a special operating mode, a p-times lower readout frequency is possible at the detector outputs than without this operating mode. A special storage location and a signal adaptation structure are used for this purpose. The transfer clock frequency corresponds to the reciprocal time interval which is necessary, with a predetermined scanning speed, to move a picture element from the centre of a detector element to the centre of an adjacent detector element; the charge displacement clock frequency is equal to the reciprocal value of the p-th part of this time interval within the TDI-CCD structure. <IMAGE>

Filed: 1990-06-15
Abstract: An electrooptic measuring apparatus having both high voltage sensitivity and femtosecond time resolution comprises coplanar transmission lines fabricated on a semi-insulating multiple quantum well structure. An electrical signal, such as from a high speed electronic device, injected onto the transmission lines creates an electrical field parallel to the layer planes of the multiple quantum well structure. Excitonic electroabsorption by the multiple quantum well structure, in response to the parallel field, changes the transmissivity of the multiple quantum well structure. An external light beam directed through the multiple quantum well structure is modulated by the changes in transmissivity. By detecting this modulation, a sampling of the electrical signal is achieved.

Abstract: At a receiver in a digital communications system, an arriving analog signal is sampled using a local clock. To correct for asynchronous timing between the local receiver clock and the remote transmitter clock, the sample values obtained using the local clock are processed by a timing adjuster. The timing adjuster corrects the sample values obtained by the local clock by evaluating at a particular time a convolution of a plurality of the samples obtained by the local clock with a raised cosine function. The particular time at which the convolution is evaluated is determined by filtering the output samples of the timing adjuster with a narrow bandpass filter. A timing difference detector is utilized to evaluate certain samples output by the filter to adaptively adjust the time at which the timing adjuster evaluates the convolution.

Abstract: A system and method for improving the quality of the output of a full-color image on a reproduction device, such as a display on a monitor or printout from a printer, that only consists of a small number of colors in comparison to the number of colors represented by the input signals. The disclosure involves specifying a new quantization method for multi-color images, rendered with orthogonal or separable color image palettes, that takes advantage of the calculations done by error diffusion. Accordingly, the image input signals are processed using the quantization error generated by one color component of a given pixel to influence the quantization of subsequent color components of the same pixel, and in such a way that the color image, so rendered, appears less grainy.
