Abstract: A security tag (10) for use with an electronic article surveillance system comprises a flexible, substantially planar dielectric substrate (20) having first (22) and second (24) sides. A first conductive pattern (26) is positioned on the first side of the substrate, and a second conductive pattern (28) is positioned on the second side of the substrate. The first and second conductive patterns cooperate to establish a resonant circuit (12), including at least one inductive element (30) and at least one capacitive element (C1) having first (32) and second (34) generally separated plates. A static dissipation member (40), such as a frangible connection member, is provided for electrically connecting together the first and second plates of the at least one capacitive element for preventing the at least one capacitive element from charging and short circuiting to thereby provide electrostatic discharge protection for the security tag. In one embodiment, the frangible connection is formed by a conductive frame member (40) positioned on the substrate and extending around at least a portion of the second conductive pattern.

Patent CA-2125194-A1 (CA)
Inventor: MONCHALIN JEAN-PIERRE
IPC: G01H9/00
Filed: 1994-06-06
Abstract: The invention relates to method and apparatus for optically detecting transient motion from a scattering surface. A broad laser beam is directed on to an area of the scattering surface of an object to be imaged to thereby scatter the laser beam and produce a plurality of modulated signals. A demodulator simultaneously demodulates the modulated signals to provide a plurality of demodulated signals to an array or matrix of detectors. The detector array simultaneously converts the demodulated light signals into electrical signals representative of the transient motion. The optical detection technique according to the invention is particularly useful for detecting small deformations produced by ultrasound, in a timely manner by parallel processing information provided by a matrix of detectors.

Title: Medicament containing a 2-arylpropionic acid derivate as a nanosol and its preparation
Inventor: SCHICK URSULA
IPC: A61K9/51
Filed: 1992-12-04
Abstract: Immediate-effect medicaments containing a pharmacologically active 2-arylpropionic acid derivate as a pharmaceutically applicable nanosol have a considerably improved action start and bioavailability of the active substance. The 2-arylpropionic acid derivatives, for example ibuprofen, flurbiprofen and ketoprofen, that are scarcely soluble in an aqueous medium, are present in a gelatine-stabilised nanosol in a form that allows these active substances to be quickly and completely resorbed already in the stomach.  The disclosed colloidal disperse system composed of a 2-arylpropionic acid derivate is prepared by selecting a gelatine or gelatine derivate according to their isoelectric point (IEP), so that their IEP is adapted to the charge of the 2-arylpropionic acid derivate particles, leading to a neutral charge when the gelatine or its derivate is combined with the undissolved 2-arylpropionic acid derivate at a determined pH value. The gelatine or its derivate are converted into an aqueous sol form, their pH value is set according to the IEP of the gelatine at a value that stabilises the nanoparticles of 2-arylpropionic acid derivate at an approximately or totally neutral charge. Before or after said last step, the 2-arylpropionic acid derivate is dissolved in the aqueous gelatine sol or a solution of 2-arylpropionic acid derivate is blended with the aqueous gelatine sol.

Title: Procedure for recovering test data transmitted on a transmission line for data line for data flows with cellular structure
Inventor: WOLF ANDREAS
IPC: H04L12/70
Filed: 1993-01-22
Abstract: (57) Abstract The invention relates to a process for rec-overing transmitted test data in cellular digital streams at the receiving end in which the test data are coded by means of code words which, in self-correlation, generate a Dirac pulse and in which a cross-correlation is undertaken on the reception side for decoding.  In order to be able to transmit a larger number of test data in coded form, a binary zero word (stored at St=1) is added to the code words on the transmission side and the various test data (e.g. 11101) are allocated to the various code words and the zero word.  The sum of the digits of the code words received and the zero word is made in addition to the cross-correlation on the reception side.

Title: Synthesis of n-substituted oligomers
Inventor: ZUCKERMANN RONALD N
IPC: A61K48/00
Filed: 1993-09-24
Abstract: A solid phase method for the synthesis of N-substituted oligomers, such as poly (N-substituted glycines) (referred to herein as poly NSGs) is used to obtain oligomers, such as poly NSGs of potential therapeutic interest which poly NSGs can have a wide variety of side-chain substituents. Each N-substituted glycine monomer is assembled from two "sub-monomers" directly on the solid support. Each cycle of monomer addition consists of two steps: (1) acylation of a secondary amine bound to the support with an acylating agent comprising a leaving group capable of nucleophilic displacement by -NH2, such as a haloacetic acid, and (2) introduction of the side-chain by nucleophilic displacement of the leaving group, such as halogen (as a resin-bound .alpha.-haloacetamide) with a sufficient amount of a second sub-monomer comprising an -NH2 group, such as a primary amine, al-koxyamine, semicarbazide, acyl hydrazide, carbazate or the like. Repetition of the two step cycle of acylation and displace-ment gives the desired oligomers. The efficient synthesis of a wide variety of oligomeric NSGs using automated synthesis technology of the present method makes these oligomers attractive candidates for the generation and rapid screening of di-verse peptidomimetic libraries. The oligomers of the invention, such as N-substituted glycines (i.e. poly NSGs) disclosed here provide a new class of peptide-like compounds not found in nature, but which are synthetically accessible and have been shown to possess significant biological activity and proteolytic stability.
