20080217410 | METHOD FOR WAKING UP IN-COUNTER FIXED SCANNERS - A method of waking up an in-counter bar code scanner from its standby mode comprises providing a sensor assembly attached to a touch plate. The sensor assembly comprises an oscillating magnet member affixed at one end and a permanent magnet attached at an opposite free end at the end of a flexible member. When a user touches the touch plate, the impact force exerted on the touch plate is transmitted to the oscillating magnet member causing the magnet to oscillate inducing an electrical signal in a pick-up coil provided near the magnet and wakes up the bar code scanner. | 09-11-2008 |
20080290170 | SCANNER SWITCHED TO ACTIVE STATE BY SENSED MOVEMENT IN QUIESCENT SCANNING MECHANISM - The disclosure generally relates to a method and apparatus for determining if an optical scanner is moving. In one embodiment the method for sensing movement of an optical scanner comprises the steps of providing an oscillating system comprising a flexible member, a magnet coupled to the flexible member, a coil disposed within a magnetically effective distance from the magnet, and sense circuitry coupled to the coil; generating a first electrical signal from the oscillations of the flexible member; amplifying the generated electrical signal; analyzing the first electrical signal to determine if the generated signal is indicative of movement of the optical scanner. | 11-27-2008 |
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 |
20100163624 | Bar Code Scanner With Environmental Sensing - A bar code scanner is disclosed which may include a scanner gun; and at least one sensor in communication with the scanner gun, wherein the at least one sensor is operable to detect at least one operating condition of the bar code scanner. | 07-01-2010 |
20120018517 | MULTIPLE RANGE INDICIA READER WITH SINGLE TRIGGER ACTUATION - A method of operating an indicia reader for reading information bearing indicia (IBI) positioned in a field of view of the reader includes: transmitting a first laser light beam adapted for scanning an IBI on a target located a first distance from the indicia reader; transmitting a second laser light beam adapted for scanning an IBI on a target located a second distance greater than the first distance from the indicia reader; activating at least one of the first and second laser light beams; scanning at least one of the laser light beams with a flat unitary scan mirror to generate at least one of a first laser light beam pattern and a second laser light beam pattern; directing light reflected from the target from either the first or second laser light beams patterns through a common receive path; the common receive path including being reflected with the flat unitary scan mirror onto a focusing mirror; the focusing mirror directing reflected light along a directed reflected light path; the directed reflected light path including an optical filter outputting directed reflected light; converting the directed reflected light into an output signal with a photodetector; decoding IBI information derived from the output signal, wherein the operating steps are completed by devices supported in a hand held indicia reader housing and wherein an operator selectively activates the first laser light beam and/or the second laser light beam with a single action trigger. | 01-26-2012 |
20130306731 | INDICIA READING TERMINAL OPERABLE FOR DATA INPUT ON TWO SIDES - Embodiments of an indicia reading terminal have a housing on which is disposed input/output devices on opposing sides of the housing The terminals are configured in one example to distinguish between the input/output devices, to activate one of the input/output devices for use by an end user, and to deactivate another of the input/output devices. | 11-21-2013 |

20090108070 | Enhanced monitoring of laser output power in electro-optical readers - Laser power monitoring arrangements interrupt power to a laser used in electro-optical readers upon detection of operating conditions not conforming to preestablished standards. An auxiliary light detector independently monitors the output power of a laser beam, and directly receives a portion of the laser beam reflected from an optical assembly operative for optically modifying the laser beam. | 04-30-2009 |
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 |
20120175421 | Optical-Information-Reading Apparatus and Control Method Thereof - In a non-reading mode, a bar code is detected by irradiating it with a laser beam from a laser source, power consumption of which is reduced, and it is determined whether or not the detected bar code is correct. The mode is changed from the non-reading mode to a reading mode in which the laser source operates at substantially full power if it is determined that the code symbol is correct. The non-reading mode continues if it is determined that the code symbol is not correct. This enables an auto-trigger function that triggers reading of the bar code automatically. Therefore, it is possible to eliminate conventional parts and/or special-purpose circuits for realizing the auto-trigger function so that the optical-information-reading apparatus can be downsized. | 07-12-2012 |
20140191039 | METHOD OF DECODING BARCODE WITH IMAGING SCANNER HAVING MULTIPLE OBJECT SENSORS - A method of decoding using an imaging scanner having multiple object sensors each associated with an object field of view. The method includes determining a moving direction of the object using at least two of the multiple object sensors. The moving direction of the object points from a first side to a second side of the imaging scanner. The method includes detecting whether a new object is presence with the object sensor located on the first side of the imaging scanner, and upon detecting the presence of the new object within the object field of view of the object sensor located on the first side of the imaging scanner, capturing an image of the new object in memory with the solid-state imager. | 07-10-2014 |
