Inventor: LACROIX CHRISTOPHE
IPC: G01N33/50
Filed: 2002-05-15
Abstract: A system utilizing cell immobilization in anaerobic continuous-flow cultures for modelling the gastrointestinal system is described. Microbial cells derived from flora, e.g. in fresh faecal samples, are used as the source of inocula for immobilisation in a mixed gel of gellan and xanthan. The beads produced are then introduced in a single or multi-stage chemostat fed with a nutrient media, and the composition and metabolic activities of the flora are monitored over time in reactors operated with conditions simulating the characteristics of different segments of the gastrointestinal tract. The conditions of this intestinal fermentation model are more akin to that for the gastrointestinal system, in which cells are naturally in the immobilized state, entrapped in fibrous particles or forming biofilms on the intestine epithelium. A use of such a system for studying various aspects of the gastrointestinal tract is also described.

Title: Methods and apparatus for a spread spectrum modulated backscatter electronic shelf label system
Inventor: CLAESSEN ALBERTUS MARIA GERARD
IPC: B65G1/137
Filed: 2002-08-01
Abstract: Techniques for an electronic shelf label (ESL) system which uses a digital modulation technique for a modulated backscatter uplink from an ESL to a communication base station (CBS) which utilizes pseudo-random sequences instead of a single continuous wave frequency. The CBS transmits a message to an ESL using a Manchester coded amplitude modulated carrier. After receiving the message, the ESL responds by reflectively modulating a continuous wave (CW) signal with a pseudo-random code sequence. Multiple pseudo-random code sequences may be chosen, with each code sequence corresponding to a particular respons e. The code sequence is modulated onto a kHz carrier which is used to reflectively modulate the CW signal received from the CBS. The CBS then receives the reflectively modulated sign al and correlates the received signal to determine message transmitted.

Title: Automatic restacking tray side guide repositioning system providing sheet stacking scatter reduction
Inventor: LYON DONALD J
IPC: B65H31/20
Filed: 2003-03-11
Abstract: In a document feeder with a superposed sheet input tray and sheet output stacking tray for feeding and then restacking print media paper sheets of variable dimensions, the lateral setting (repositioning) of the at least one variable position side guide of the input tray to the sides of the input sheets automatically correspondingly resets the corresponding side guide of the underlying output stacking tray, to reduce sheet scattering in the sheet stacking, especially skewed sheets. This may be accomplished by a simple direct mechanical integration of these respective side guides into a single repositionable component with upper and lower extending sheet edge guide portions.
Patent CA-2421740-A1 (CA)
Title: Multifocal ophthalmic lens with induced aperture
Inventor: GRIFFIN RICHARD A
IPC: G02C7/02
Filed: 2001-09-06
Abstract: Multifocal lenses are defined by nonconical aspheric optical surfaces. Various alternative surface shapes provide a central distance vision region surrounded by an optical step. The optical step has repidly increasing power in the radial direction which creates an induced aperture through which the cortical elements of the vision system are induced to concentrate. The induced aperture results in increased clarity in distance vision. Nonconical aspheric optical surfaces are defined to produce the desired optical power distributions. These surface functions are also provided in form of polynomial series for simplicity of use in computer driven lathes for shaping contact lenses. To allow increased manipulation of the defining functions additional elements such as conic terms are added. To improve near vision correction in some configurations, an annular near vision region extends radially outward from the optical step. To improve low light distance vision, power is reduced in the lens region outside the mesopic pupillary dimension. In alternative embodiments, the distance vision region and optical step are formed by cyclic functions. These have benefits in ease of manipulation to fit various specific user geometry requirements. In some configurations, an extended near vision region is used outside the optical step to improve near vision correction. The invention includes contact lenses, scleral lenses, intraocular lenses, and lenses impressed or surgically shaped within the corneal tissue as well as methods of designing and fitting these lenses. Although nominally positive power lenses are also within the present invention, negative lenses gain particular benefit due to decreased lens thickness at the lens perimeter and consequent reduced spherical aberration.

Title: Method and device for accepting articles in the form of sheet-type material
Inventor: HOBMEIER RALF
IPC: G07D13/00
Filed: 2001-10-01
Abstract: The present invention relates to a method and apparatus for accepting sheet material, in particular papers of value such as bank notes, checks, etc., whereby different groups of sheet material are successively accepted and stored. In a known method and corresponding apparatus for accepting groups of sheet material such as bank notes, the bank notes coming from a deliverer are checked and stored in a storage container in the order of their input. Thus it is not always recognizable without doubt subsequently, e.g. in cases of malfunction, which deliverer certain bank notes come from.  The present invention starts out from the consideration that each group of sheet material is assigned at least one separation means and the separation means are stored at least partly together with the associated group of sheet material for separating the associated group of sheet material from other groups of sheet material.
