20080291979 | Method and Spread Spectrum Software Receiver for Satellite Navigation - A spread spectrum signal receiver includes a radio signal processing unit, which is at least partly implemented in software running on a processor. The processing unit is adapted to estimate a respective processing demand required to produce position/time related data based on each subset of a number of candidate subsets of signal sources among a group of potential signal sources. Each candidate subset contains at least a minimum number of signal sources, which is necessary to produce the position/time related data of a desired quality. The processing unit is adapted to select a set of preferred signal sources from the group of potential signal sources based on a candidate subset, which is associated with a lowest estimated processing demand during a subsequent receiver operating period. Then, the receiver receives spread spectrum signals from the selected set of signal sources, and based on the received signals produces position/time related data. | 11-27-2008 |
20090002234 | Spread Spectrum Software Receiver - A spread spectrum signal receiver comprises a radio signal processing unit, at least partly implemented in software running on a processor. The processing unit determines a candidate collection of subsets of signal sources from a group of potential sources, by the criterion that an anticipated processing intensity required to derive position/time related data from that subset is equal to or less than a maximum specified processing intensity. Each subset contains at least a minimum number of signal sources necessary to produce position/time related data. The processing unit also selects a set of preferred signal sources from a candidate subset, based on a highest estimated quality of the position/time related data attainable during a subsequent operating period for the receiver without exceeding the maximum specified processing intensity. During the subsequent operating period, the receiver receives spread spectrum signals from the selected set of signal sources and produces position/time related data therefrom. | 01-01-2009 |

A control module in the device controls execution of a processing job with respect to a stored data set by allocating individual processing tasks to at least one of the at least two processor units based on a current processing load on each processor unit. | 10-15-2009 |

20100102128 | Laser power control arrangements in electro-optical readers - A laser power control arrangement and method in an electro-optical reader for reading indicia includes an energizable laser for emitting a laser beam having an output power along a path. An internal light detector, e.g., a monitor photodiode, is mounted inside the laser for monitoring the output power of the laser. An external light detector, e.g., an auxiliary photodiode, is mounted outside the laser for monitoring the output power of the laser independently of the internal light detector. A guide, advantageously a light pipe or a diffuser, is positioned outside the laser in the path of the laser beam for guiding the laser beam from the laser to the external light detector. A controller is operatively connected to each light detector, for controlling a monitored output power of the laser beam by deenergizing the laser when the monitored output power of the laser beam exceeds a safe power level limit. | 04-29-2010 |
20110290885 | METHOD AND APPARATUS FOR INCREASING BRIGHTNESS OF AIMING PATTERN IN IMAGING SCANNER - A method and apparatus for using in a barcode reader. The apparatus includes an aiming lens assembly including an irregular-shape lens, an aiming light source positioned behind the aiming lens assembly, and an aperture with the desired aiming pattern shape placed in close proximity to the aiming source for generating a visible aiming light pattern towards the target object. The irregular-shape lens includes at least a recess for accommodating the imaging lens when the irregular-shaped lens is assembled into the apparatus with other components. | 12-01-2011 |
20120085824 | OBJECT PROXIMITY SENSOR RECESSED INTO IMAGING READER - An electro-optical imaging reader includes a chassis mounted in a housing, a window spaced from a rear wall of the chassis, an imaging module for capturing return light from a target through the window over an imaging field of view, a controller for operating the reader in a standby state in which no target is read, and for processing the captured return light to read the target during a reading state, and an object sensing assembly supported by the rear chassis wall and spaced from the window. The object sensing assembly senses the presence of an object bearing the target in front of the window by detecting return sensing light from the object through the window over a sensing field of view that at least partially overlaps the imaging field of view, and triggers the controller to change from the standby state to the reading state upon such detection. | 04-12-2012 |

The reflector is configured to redirect at least some of the second portion of the invisible light toward the target object. The photodetector is configured to detect returned invisible light from the target object to generate an electrical signal. | 02-28-2013 |

20140131596 | REDUCING PERCEIVED BRIGHTNESS OF ILLUMINATION LIGHT SOURCE IN ELECTRO-OPTICAL READERS THAT ILLUMINATE AND READ TARGETS BY IMAGE CAPTURE - Targets to be electro-optically read by image capture are illuminated with illumination light emitted from an illumination light source and directed along an illumination path through a window to the targets, and return light from the targets is captured through the window and projected along an imaging path to an array of light sensors of an imaging system. An optical element is located in both the illumination path and the imaging path, and has a light-reflecting, non-diffusing portion for directing the captured return light incident on the light-reflecting portion along a folded imaging path to the array, and a light-diffusing portion for diffusing the illumination light incident on the light-diffusing portion along a folded illumination path to scatter and blur an image of the illumination light source, to increase an apparent size of the illumination light source, and to reduce a perceived brightness of the illumination light source. | 05-15-2014 |
