摘要:
A data reading system, and associated methods of operation, for locating and tracking a position of tagged items on a conveyor system. The system includes a data reader and a conveyor system operable to transport the tagged items through a read region of the data reader. A processor, in operative communication with the data reader, obtains data from an item tag being passed through the read region at a first time, at a second time, at a subsequent third time, and so forth. Based on the readings, the processor estimates an initial position of each item tag and determines an order at which each item reaches a reference position on the conveyor system.

The device for the acquisition and automatic processing of data obtained from optical codes comprises a CMOS optical sensor; an analog processing unit connected to the optical sensor; an analog/digital conversion unit connected to the analog processing unit; a logic control unit connected to the CMOS optical sensor, the analog processing unit and the analog/digital conversion unit; and a data-processing unit connected to the logic control unit and the analog/digital conversion unit. The CMOS optical sensor and at least one of the analog processing, analog/digital conversion, logic control and data processing units are integrated in a single chip. The data processing unit processes the digital signals corresponding to the image acquired by the CMOS sensor and extracts the optically coded data.
摘要:
An optical information acquisition device that comprises a main body and a connector assembly associated with said main body and comprising three connectors. The connector assembly can be rotated with respect to said main body between a first operating position wherein said connectors extend substantially perpendicularly to a first side of said main body and a second operating position in which said connectors extend substantially perpendicularly to a second side of said main body. The three connectors are positioned at the vertices of an acute-angled triangle, more preferably at the vertices of an equilateral triangle.

A reading apparatus (5) for reading optical information (I) comprises a body (6) provided with a frontal face (7); optical information (I) acquisition means, which is arranged at a distance from the frontal face comprised between a minimum significant work distance, in particular 50 mm, and a maximum work distance, in particular 350 mm, defining a significant work range; illuminating means for emitting an illuminating pattern (2) such as to enable the optical information to be acquired; aiming means for emitting an aiming pattern (3) such as to indicate to a user a field of view of the apparatus; indicating means for emitting a reading apparatus outcome pattern (4) such as to supply indications to a user relating to the acquisition of the optical information (1). The illuminating means, the aiming means and the indicating means comprise respective non-coherent light sources. At least the illuminating means and/or the aiming means and/or the indicating means of the apparatus (5) are configurable by a plurality of operating parameters, for each of which respective permissible values are selectable that are able to influence the behaviour reading apparatus (5) with an effect that is detectable by said user during operation of the reading apparatus (5), The plurality of operating parameters comprises the wavelength of each of the light sources, the permissible values of the wavelength of the source of the aiming means are comprised in a range from 430 to 470 nm, the permissible values of the wavelength of the source of said illuminating means are comprised in a range from 590 to 650 nm; the permissible values of the wavelength of the source of the indicating means are comprised in a range from 530 to 560 nm. The permissible values of said wavelengths are such that the perception of the illuminating pattern (2), of the aiming pattern (3) and of the reading outcome pattern (4) is optimum to the human eye in consideration of the physiological properties thereof and this perception occurs with reduced visual fatigue to the user over the entire significant work range.
