IPC: E04H9/02
Filed: 1995-07-12
Abstract: A device for seismic isolation is invented to be placed under a superstructure, such as a building, a structure, or heavy equipment, so as to facilitate unhindered horizontal movements of the super-structure under earthquake, and thereby reduces the seismic forces transmittable to the superstructure.    The device is designed to operate within a pair of bearing plates placed under a base mat.  The flattened facets of the device provide control to the horizontal movements, help to reduce the bearing stresses to the bearing plates and to the base mat, and prevent unneeded movements under frequent or minor disturbances such as wind storms.   The stepwise rolling action bypasses the limitation posed by the high friction coefficients found among common material of construction that would hinder the required free motion.  The present invention replaces the need for expensive state-of-the-art seismic isolators, which rely on elaborate elasto-meric fixed-bearings, or elastomeric sliding assemblages involving special treated low-friction steel or alloys.          The invention enables seismic isolation to become a practical and affordable tool for millions of people dwelling in high-seismic areas of the world.

Title: Soft error correction in a tdma radio system
Inventor: MUSTEL PETER ALEXANDER
IPC: H03M13/03
Filed: 1994-12-01
Abstract: In a TDMA cellular telephone system, an error concealment method provides parameter interpolation based on soft quality measures that will enhance the speech quality under bad channel conditions compared to prior methods of repeating previous voice data frames. Specifically, the soft technique of the present invention uses a weighted combination of previous and present frame parameters, where the weighting reflects the probability of error. The present invention will improve the masking of errors compared to hard actions based on a binary detection, especially when the binary detection fails or when the received frame is declared as being "good". The method can also utilize parameter based soft information without increasing the bitrate.

IPC: C08L3/02
Filed: 1994-01-14
Abstract: The present invention provides a process for the manu-facture of a product essentially containing amylose from vegetable materials, in particular from peas. To this end, the flour is mixed with an alkaline decomposing agent, and then a separation into a liquid protein phase and a solid phase containing polysaccharide is performed. The solid phase is then re-suspended and subjected to several sifting steps, followed by at least one washing step and subse-quently a drying step. From such polysaccharide material, in particular from amylose, any kind of moisture-resistent, flexible, and in particular biodegradable articles can be procuded by means of conventional plastics technologies, in particular the injection molding technique. A particular advantage of the present invention resides in the fact that the thermoplastic polysaccharide material, which is pro-duced from renewable raw materials, can also be processed into sheets which in turn can then be worked with conven-tional plastics techniques.

Abstract: The error-correction coding function of an SD-VCR for recording and reproducing an ATV signal is modified to exclude trick-play data from outer error-correction coding in two-dimensional Reed-Solomon coding of normal play data, to improve error-correcting capability for the normal-play data.      The same error-correction coding used as inner error-correction coding in the two-dimensional.Reed-Solomon coding of normal play data is performed on the trick-play data as well as on the outer error-correction coded normal-play data.      The resulting inner codes are preferably diagonal-scan interleaved before recording, at least for the normal-play data. During reproduction, after de-interleaving when interleaving was performed during recording, the inner error-correction coded data are decoded and separated into trick-play data and outer error-correction coded normal-play data.      Outer error-correction coded normal-play data are decoded during normal play.
