Patent CA-2303929-A1 (CA)
Title: Sulfo-n-hydroxy succinimide and method of preparation
Inventor: WILKES MARTY CAREY
IPC: C07C303/22
Filed: 1998-09-17
Abstract: The salt of a sulfonated succinic acid is cyclized, then converted to novel sulfonated hydroxamic acids by reaction with hydroxylamine (which is added or formed in situ), and the novel hydroxamic acid is then cyclized to the sulfo-N-hydroxysuccinimide salt. Novel sulfo-hydroxamic acid intermediates are formed during this procedure. A process of forming a sulfo-N-hydroxysuccinimide by cyclizing a sulfohydroxamic acid is also described. Alternatively, the present invention describes a novel method for the synthesis of sulfo-N-hydroxysuccinimide salts in which commercially available sulfosuccinic acid salt in an aqueous medium is heated in the presence of an alcohol to form a diester of the succinic acid sulfonate. The diester is then reacted with hydroxylamine (e.g., from the hydrochloride salt) (e.g., in an alkaline buffered aqueous environment, e.g., at room temperature) to form the sulfo-N-hydroxysuccinimide. This is an extremely simple and direct process that does not produce a significant level of irremovable impurities.

Patent CA-2305439-A1 (CA)
Inventor: KOLNES STEINAR
IPC: H04Q3/72
Filed: 1998-09-30
Abstract: A method for recording and storing received signals, e.g. sound signals, in connection with a telephone apparatus receiving said signals from a remote apparatus. The telephone apparatus also receives information about the telephone number of the remote apparatus, to which it is interconnected through a telephone network, with the purpose of being capable of playing back the stored signals at a later stage. It is intended to indicate a new method for simplified storing of information which, upon being played back, can identify the caller when the calling telephone number is received over the telephone line. The recording of e.g. sound signals (voice) from said remote apparatus and/or the telephone apparatus called, starts when a telephonic connection has been established with a remote apparatus, and stops after a predetermined time, whereupon the telephone number of the remote apparatus is stored searchably in the data storage medium.

Inventor: VAN ACKERE MICHEL DIANE CYRIEL
IPC: H04M1/724
Filed: 2000-05-29
Abstract: A telecommunication user terminal, such as a traditional telephone set or a mobile telephone, provided with a personal address book or internal database (PTD), e.g. located on a user's smart-card. The internal database has several memory locations (1A1,...,IA5, ...) each storing a call reference that may be selected as calling number by a search key entered by the user on a keyboard (KB) of the telephone. The internal database further has an extra memory location (XE) that stores an extra call reference to a second database (TDS) and that is used in case no matching is found with the other call references. The second database is an external directory service controlled by an operator or service provider. The internal and external database complement one another in a transparent way for the user owing to a fall- through selection circuit (FT) also forming part of the telephone.

Title: Carrier reproduction circuit
Inventor: SHINJO SOICHI
IPC: H04L7/00
Filed: 1998-12-25
Abstract: A carrier reproduction circuit that performs stabilized operation even when receiving low C/N signals. Carrier reproduction is carried out by a method, wherein the phase of a demodulated received signal of a known pattern is detected by a frame sync timing circuit (4); based on the detected phase of the received signal, a phase error table of either an absolute phase or the absolute phase shifted by 180 degrees is selected according to a phase convergence point in a phase error detector (8) for carrier reproduction; the output based on the difference in phase between the phase obtained from the arrangement of the received signal points and the phase convergence point is obtained from the selected table; and the frequency of the reproduction carrier is controlled by an AFC circuit (10) so that the phase obtained from the signal point arrangement may coincide with the phase convergence point.

Abstract: A fiber light source (3) having, for instance, a 980 nm pump laser (28) for pumping an erbium-doped optical fiber (15) via a 980/1550 nm WDM coupler (27).  The pumped fiber emits 1550 nm light. A portion of the 1550 nm light goes to a filter (33) via the WDM coupler (27). The filter (33) shapes the spectrum of the 1550 nm light. The filter (33) is a passive device that may be made from erbium-doped fiber. From the filter (33) the 1550 nm light goes through an isolator (21) or a circulator on to an optical device for which the light is specially made. Such device may be a fiber optic gyroscope. By adding a narrowband optical fiber grating at the output of the pump laser to tune its output, the fiber light source is further improved in stability under variations of ambient temperature and light source drive current.
