A distance measuring device is disclosed that includes a controller operably coupled with a receiver to receive different amplification channels. The controller includes a time of flight core configured to determine time of flight information for the light pulse; and a decider block configured to determine a measurement correction value for the device based on a determination of a presence of a reflective background that is different than a measurement correction value selected for the device when there exists a diffuse background or an absence of a background into a reading field.

Safety laser scanner and related method for adjusting distance measurements to compensate for reflective backgrounds

A calibration process is started by a capacitive input variation when a capacitive button is pressed on a barcode reader. Or, the calibration process is started by the barcode reader scanning a configuration label or special label or barcode after the capacitive button on the barcode reader is inoperative. The calibration process realigns the input and the threshold to correctly configure the capacitive button.

Safety system

Various embodiments of the invention are implemented with a mobile camera and safety laser scanner. A mobile computer can be used to show a visible infrared beam on the display of the mobile computer. The mobile computer can function as a safety tool to identify regions or locations where a laser beam might penetrate. The mobile computer can determine if the laser beam has penetrated a safety region or zone. Sensors can be used to determine when a laser beam may become dangerously close to an operator, especially with the use of automated guided vehicle that is moving around and has a scanning laser.

The present invention relates to a distance sensor suitable for calculating a processed distance of a target object without contact, including: a contactless measuring circuit suitable for emitting an output signal proportional to the distance of said target object for a plurality of time intervals, so as to obtain a plurality of measurements of the distance of said target object without contact; a first processor circuit suitable for processing said output signals coming from said measuring circuit, so as to calculate a first average distance from said target object based on the average of N distance measurements in output coming from said measuring circuit, said N measurements being consecutive in time and including the last distance measurement emitted by said measuring circuit; a second processor circuit suitable for processing said output signals coming from said measuring circuit, so as to calculate a second average distance from said target object based on the average of M distance measurements in output coming from said measuring circuit, said M measurements being a subset of said N measurements with M&#x3c;N, consecutive in time and including the last distance measurement emitted by said measuring circuit; a first comparator circuit suitable for calculating a first difference between a value function of said first average distance and a value function of said second average distance; and a third processor circuit suitable for comparing said first difference with a first threshold and for emitting in output a processed distance value, said processed distance value being equal to a value function of said first average distance if said first difference is less than or equal to said first threshold, or being equal to a value function of said last distance measurement emitted by said measuring circuit otherwise. Furthermore, the invention relates to an operating method of said sensor.

Optical scanner

A clutter filter configuration tool for a safety laser scanner. The clutter filter configuration tool may first operate the safety laser scanner in an environment to learn the environmental clutter level and present the same to a user. Subsequent to this 'teach-in' phase, the configuration tool may provide a clutter filter selection process which presents the environmental clutter level to the user and allows the user to select a suitable configuration for a clutter filter. The configuration tool may also provide a clutter filter simulation process wherein the clutter filter chosen by the user is verified and a test is performed using the selected clutter filter. The results may be reported on a visualized graph. The configuration tool may also determine a real area to be monitored utilizing a floor projection area and an orientation of the laser scanner.

Clutter filter configuration for safety laser scanner

A laser scanner which includes a light source which emits a light beam and a scanning mirror rotatable about an axis which reflects the light beam through a tilted protective window toward a scanning area and which directs return light from objects toward receiving optics. The laser scanner may include a collecting mirror which receives the return light, and an interference filter disposed between the collecting mirror and the scanning mirror. The window may include an anti-reflective coating which reduces reflection of internally scattered light. The tilted window may direct the reflective component of internally scattered light into a zone where an energy light absorber is present. A bulkhead system which may include a separation baffle may be provided to prevent light incident on the interference filter at an angle which is below an acceptance angle of the interference filter.
