Title: Surge arrester
Inventor: BOBERT PETER
IPC: H01T1/14
Filed: 2002-07-15
Abstract: The invention relates to an overvoltage arrester comprising a central electrode (1) and at least one outer electrode (2), in which an electrically conductive spring band (3) is attached to the central electrode (1), and a spring force (F) is exerted onto the outer electrode (2). According to the invention, an electrical component (4) is placed between the spring band (3) and the outer electrode (2). Said component is non-conductive during the occurrence of the trigger voltage of the overvoltage arrester and generates heat during current conduction. The spring band (3) rests against an electrically conductive contact element (5), which is attached to a spacer element (7) by means of a meltable material (6) and located at distance from the outer electrode (2). When the material (6) is melted, the contact element (5) is pressed against the outer electrode (2) by the spring band (3). The triggering mechanism is advantageous in that it reacts quickly thereby reducing the formation of sparks and thus the fire hazard.

IPC: G01N37/00
Filed: 2002-06-26
Abstract: Compositions and methods of preparing functional thin films or surface coatings (100) with low non-specific binding are described. The thin films contain specified functional groups and non-specific binding repellant components. The thin films are either covalently bound to or passively adsorbed to various solid substrates (102). The specified functional group (110) provides specified activity for the thin film modified solid surfaces and non-specific binding repellant components (104) significantly reduce the non-specific binding to the thin film modified solid surfaces. Non-specific binding repellant components do not affect specified functional group's activity in the thin films. In these methods, specified functional groups ar e anchored to the solid substrates through a spacer (114). Surface coatings ar e also described having both non-specific protein binding properties combined with functional groups for specific binding activity thereby providing surfa ce coating that specifically recognize target proteins but limit binding to non - specific protein.

Abstract: The objective of the present invention is to identify compounds having an inhibitory effect on adipocyte differentiation, and to provide pharmaceutical compositions and food compositions for prevention, improvement, or treatment of obesity or obesity related diseases. By enthusiastically studying natural products that inhibit the differentiation induction of adipocyte precursors into adipocytes, sesquiterpenoid derivatives, which are extracts from a Compositae plant, Calea, growing in Central and South America, were demonstrated to have an excellent inhibitory effect on adipocyte differentiation induction. Calea extract or the sesquiterpenoid derivatives are expected to be used in pharmaceutical compositions and food compositions for prevention, improvement, or treatment of obesity or obesity related diseases.

IPC: H04N21/2365
Filed: 2002-09-11
Abstract: Transcoder multiplexers that transport digital packets, such as MPEG2 packets, between boards in a chassis using a serial differential protocol are disclosed. The disclosed multiplexers achieve data transfer rates at least twice as fast as conventional systems. Digital data packets are thereby efficiently communicated to target processing engines on other boards across the backplane. Prior art requirements for custom backplane designs, together with discrete hardware for sending data in parallel form between boards, are obviated. Instead, a backplane architecture designed specifically for IP data traffic from any slot to any slot is utilized. Also, an improved protocol is applied for transmitting data serially between boards to provide an inexpensive, upgradeable and flexible hardware solution. Preferred embodiments use LVDS transmitter/receiver pairs with high link speeds.

Inventor: TERASAWA DAISUKE
IPC: H04W48/16
Filed: 2002-09-19
Abstract: Techniques for searching in asynchronous systems are disclosed. In one aspect, a plurality of codes, such as SSCs, are correlated with a received signal at a plurality of offsets to produce a code/slot energy corresponding to each code/slot boundary pair. Unique subsets of the code/slot energies are summed to produce code sequence energies, the maximum of which indicates a located code sequence and slot boundary. In another aspect, the correlation is performed by sub-correlating the received signal with a common sequence, and performing a Fast Hadamard Transform (FHT) on the results. In yet another aspect, one sub-correlator can be used to search a plurality of peaks simultaneously. Various other aspects of the invention are also presented.  These aspects collectively have the benefit of circuit area and search-time efficiency which translate into reduced costs, increased standby time, increased acquisition speed, higher quality signal transmission, increased data throughput, decreased power, and improved overall system capacity.

Abstract: L'invention concerne une amélioration de procédé et de dispositif pour la récupération d'énergie et de particules durant l'élaboration de farine de maïs nixtamalisée, par précuisson avec une solution de chaux aux fins de cuisson partielle, en réduisant l'énergie utilisée pour la précuisson, et lavage par recyclage d'eau chaude. On stabilise ensuite la teneur en humidité, puis le maïs est broyé et séché dans un flux d'air ultra-chaud, avec réduction de l'énergie utilisée par recyclage des rejets d'air chaud. On piège la poussière sur une partie des rejets d'air chaud réutilisée pour le préchauffage de l'air de combustion. Un dépoussiérage humide des rejets d'air chaud restants intervient ensuite, avec réutilisation d'eau chaude et évacuation de rejets d'air. Le traitement consiste ensuite à refroidir puis à sécher plus avant les particules séchées-broyées, à séparer et récupérer une fine mouture de farine dans la mouture grossière que l'on aspire afin d'isoler les enveloppes de maïs sous forme de déchets, avec les particules qui résultent du piégeage et du dépoussiérage humide des rejets d'air chaud. Un nouveau broyage et un tamisage de la mouture grossière donnent enfin une farine de maïs susceptible d'être utilisée comme farine à tortilla et autres produits analogues.
