| 20110279808 | FOLDED PATH LASER RANGEFINDER ARCHITECTURE AND TECHNIQUE INCORPORATING A SINGLE CIRCUIT BOARD FOR MOUNTING OF BOTH LASER EMITTING AND DETECTING ELEMENTS - A handheld, folded-path, laser rangefinder architecture and technique incorporating a single circuit board for mounting of both the laser emitting and detecting elements is disclosed. The architecture disclosed provides an efficient and low cost design for a laser rangefinder, and by eliminating the conventional provision of separate circuit boards for the laser transmitting and receiving elements, reduces the overall size of the unit and its cost of manufacture by concomitantly eliminating unnecessary interconnecting cables and the like. | 11-17-2011 |
| 20110221606 | SYSTEM AND METHOD FOR DETECTING A MOVING OBJECT IN AN IMAGE ZONE - A system and method for detection of a moving object in an image zone for possible use in the field of road and traffic safety related and/or gate monitoring systems includes an image sensor for imaging a field, a user interface for defining at least one detection zone within the field, a processor coupled to the user interface and the image sensor for detecting if a moving object has entered the at least one detection zone and an alarm providing a signal in response to detection of a moving object within the at least one detection zone. | 09-15-2011 |
| 20110187854 | INTEGRATED STILL IMAGE, MOTION VIDEO AND SPEED MEASUREMENT SYSTEM - Devices capable of capturing still and motion imagery are integrated with an accurate distance and speed measuring apparatus. By measuring the changing distance of the target over that time, a target's speed can be determined. At substantially the same time as the target's speed is determined, imagery of the target is captured in both a still and moving format. Using a queuing mechanism for both distance and imagery data along with time stamps associated with each, a target's image, both in motion and still, can be integrated with its speed. In situations in which a still image is unavailable, a target's speed can be associated with a portion of a continuous stream of motion imagery to a point where a positive identification can be captured with a still image. | 08-04-2011 |
| 20100202662 | VEHICLE CLASSIFICATION BY IMAGE PROCESSING WITH LASER RANGE FINDER - An image capture device captures a plurality of sequential images of a vehicle in motion. At substantially the same time a collocated rangefinder determines the distance between the vehicle and the image capture device. Each of the plurality of images may be segmented based on the rangefinder point of reference. The portion of each image representing the vehicle is extracted based on its motion with respect to a stationary background. Knowing the size of the vehicle with respect to the image and the distance that the vehicle is from the image capture device, the image data is converted to real world dimensions. Using these real world dimensions a vehicle classification is determined. | 08-12-2010 |
| 20100103004 | CORRELATED NOISE AND SPURIOUS SIGNAL REDUCTION - Error introduced by analog to digital conversion of a set of laser pulses can be reduced by shifting the clock reference time associated with the firing of the laser pulse. A timing offset module shifts the timing reference of each laser pulse. Digital codes generated by the ADC from the received signals are realigned and summed eliminating systematic error introduced by clock driven operations of the ADC. A comparison of the total ADC output of detected laser pulses over a select number of clock intervals enables a return signal to be distinguishable over the systematic error. | 04-29-2010 |
