Inventor: KONERMANN STEFAN
IPC: B29C48/10
Filed: 1990-06-19
Granted: 2000-09-12
Abstract: The invention relates to a process for the fine correction of the thickness profile of a blown portion (10) in the production of bubble film in which the flow of cooling air (6) is varied in individual peripheral regions of the film bubble. According to the invention, at least part of the cooling air is taken via an exit slot (20) which is divided into individual separately fed segments in the peripheral direction of the film bubble and the supply of additional cooling air (4) via the exit slot (20) is, for example, controlled per segment using radial blowers (7). In this manner it is possible accurately to regulate the cooling action and thus the film thickness in the individual peripheral regions of the film bubbles.

Title: Non-destructive materials testing apparatus and technique for use in the field
Inventor: SANSALONE MARY J
IPC: G01N3/06
Filed: 1991-12-13
Granted: 1995-03-14
Abstract: The apparatus of the invention comprises a portable, hand-held unit having a plurality of impactors disposed therein. The plu-rality of impactors comprise a number of differently weighted spheres that are each designed to impart a different impact energy into the structure to be tested. Each sphere is disposed on a distal end of a spring-steel rod. A particular weighted sphere is chosen by a selector disposed on the testing unit. The sphere is withdrawn from the rest position by a pair of jaws to a given height above the structure. At a predetermined released point, the sphere is released, causing it to impact the structure with a specific duration and im-part a given energy thereto. The impact produces stress waves that are reflected from the internal flaws and external surfaces of the structure. The reflected waves are detected by a transducer that con-verts the stress waves into an electrical signal (displacement wave-form). The waveform is then processed to provide an amplitude spectrum, and in the case of plates, a reflection spectrum. For plates, the reflection spectrum can be interpreted by a neural ne-twork which provides results that are indicative of either the thick-ness of the structure or of the defects disposed therein.

Title: Data security arrangement for semiconductor programmable logic devices
Inventor: AUSTIN KENNETH
IPC: G06F21/00
Filed: 1992-10-09
Granted: 2002-12-24
Abstract: A data security arrangement is provided to protect configuration data CDI to be stored in static random access memories SRAM in semiconductor programmable logic devices PLD. The configuration data, which is vulnerable to illegal duplication, is normally held in a read only memory ROM, typically an erasable programmable read only memory. A data coding means is provided to code the configuration data to be loaded to the PLD and a data decoding means is provided in the PLD to decode the coded configuration data.      The coding and decoding means each incorporate maximal length shift registers which generate a pseudo-random sequence of bits. A key value is input to the shift register in the coding means forcing it to start at a particular point in the sequence. The output (bits B28 and B31) of this register is combined in an EXCLUSIVE-OR gate with configuration data and coded data is written to the read only memory ROM. The decoding means in the PLD has a corresponding key value held in a non-volatile memory in the PLD. This is applied to the register of the decoding means, whose output (bits B28 and B31) are combined in an EXCLUSIVE-OR gate with coded configuration data CDIC read from the ROM to produce decoded configuration data CDOD to be stored in the memories.

Abstract: A circuit arrangement for evaluating the signal of a capacitive measuring sensor (Cs) in particular a humidity sensor comprises a multivibrator (MV) which is remotely adjustable with respect to its frequency in order to provide a frequency independent from the measuring value as well as a monoflop (MF) which is triggered by the trailing edge of the pulses of the multivibrator and where the pulse length is determined by the measured value of the capacitive measuring sensor (Cs) connected to it. The pulses formed by the monoflop (MF) are integrated (R1,C1) and fed to one input of an amplification - and offset subtraction-circuit. With the output signal of this circuit the supply voltage of the circuit components may be increased in order to compensate for a degressive characteristic of the sensor (Fig. 1).

Granted: 1997-12-30
Abstract: A method by which absolute static lock may be applied at media level,to files and directories in File Allocation Table (FAT)-based storage media,of single machine personal microcomputers running within the Disk Operating System (DOS) or equivalent environment is disclosed. To apply absolute static lock at media level on a target file or directory, the directory entry data field on disk for the target file or directory in the host machine is located and read into a convenient area of the host machine memory. The directory entry data field is restructured according to the procedure and in the non-DOS format of this invention.The original directory entry data field on the target media is replaced with the restructured non-DOS directory entry data field of this invention.The corresponding target file cluster data contained in the FAT is protected. Encryption of the target file contents may be incorporated into the absolute lock process if required. Target files or directories upon which the absolute static lock of this invention has been successfully applied cannot be accessed by DOS at media level,for the critical operations of read,copy, overwrite and erase.The reverse unlock process,by which the previously applied absolute static lock may be removed from a target file or directory,restoring it to the original unlocked DOS state,is also disclosed.In the special case where the target media is a floppy,the method of applying,or removing,absolute static lock to the floppy disk,is also disclosed.
