Abstract:
There is described an indicia reading terminal having an image sensor array including a plurality of pixels, a first optical assembly for focusing imaging light rays onto a first set of pixels of an image sensor array and a second optical assembly for focusing imaging light rays onto a second set of pixels of the image sensor array. The indicia reading terminal can be adapted to process image data corresponding to pixels of the image sensor array for attempting to decode a decodable indicia.
Abstract:
An imaging system for obtaining an image of a display of an electronic device presented by a presenter holding the electronic device includes a housing having an imaging subsystem disposed in the housing. The imaging subsystem comprising an image sensor array and an imaging assembly operative for focusing an image of the display on the electronic device onto the image sensor array. A support comprising a support surface is operable for allowing the presenter to hold the electronic device against the support surface so that the display on the electronic device is positioned towards the imaging system while the image of the display is obtained.

Abstract:
A method for obtaining non-water-soluble powders comprising antimicrobial activity and having quaternary ammonium salts adhered thereto. The invention also includes the powders thus obtained and the use thereof as antibacterial agents. The invention enables the production of non-soluble organic or inorganic powders having a particle size of 5 to 500 μm, having a quaternary ammonium salt adhered to the surface thereof and fixed on the surface. When deposited on textile materials, the powders enable bacterial and viral decontamination, by means of filtration, of polluted water or aqueous environments. Textile materials impregnated with powders according to the invention can be used in the production of breathing masks, protective garments or other items, in particular in a hospital environment. The antibacterial properties of the powders are at least twice as high as the antibacterial properties of the same quaternary ammonium salt used in isolation.

In Chemical Formulae 1 and 14, each substituent is the same as defined in the detailed description
Abstract:
The present invention relates to a communication method, system and signal, and in particular to a method and system for communicating information in a digital signal. It has particular application to satellite or terrestrial packet-based multi-user radio communication systems. A method for communicating information in a digital signal comprising data symbols is disclosed, wherein the information is encoded in a sequence characteristic of pilot symbols distributed amongst the data symbols, such that a receiver is able to determine the sequence characteristic and retrieve the transmitted information. The invention allows information to be encoded into a sequence characteristic of pilot symbols, rather than relying on modulating such information onto the pilot symbols themselves. This allows a significantly larger number of pieces of information to be transmitted than hitherto possible, and the technique is more resistant to large frequency errors than prior techniques.
Abstract:
Provided is a photosensitive resin composition that is developable with an aqueous alkaline solution and is suitable for the production of a color filter for an image sensor. The composition comprises an alkali-soluble resin, a photopolymerizable monomer, a photopolymerization initiator, colorants and a solvent. As the colorants, a pigment and a dye are used in combination. The use of the composition enables the formation of fine pixels that exhibit excellent color reproduction and contrast. Therefore, the composition can be used to produce a high-resolution color filter for an image sensor.
Abstract:
The present invention embraces an optical wavelength division multiplex (WDM) transmission system, especially a WDM passive optical network, typically including a central node having a first and a second WDM port and a remote node having a first and a second WDM port and a plurality of channel ports, the central node first WDM port being connected to the remote node first WDM port via a bidirectional single-fiber optical working path and the central node second WDM port being connected to the remote node second WDM port via a single-fiber bidirectional optical protection path, and a group of basic optical node units (ONU's) each of which is connected to a respective remote node channel port via a bidirectional optical ONU path, each ONU including an optical receiver for receiving a downstream optical channel signal and an optical tunable transmitter for creating an upstream channel signal.
