  • Patent number: 10944891
    Abstract: A vision system camera, and associated methods of operation, having a multi-core processor, high-speed, high-resolution imager, FOVE, auto-focus lens and imager-connected pre-processor to pre-process image data provides the acquisition and processing speed, as well as the image resolution that are highly desirable in a wide range of applications. This arrangement effectively scans objects that require a wide field of view, vary in size and move relatively quickly with respect to the system field of view. This vision system provides a physical package with a wide variety of physical interconnections to support various options and control functions. The package effectively dissipates internally generated heat by arranging components to optimize heat transfer to the ambient environment and includes dissipating structure (e.g. fins) to facilitate such transfer. The system also enables a wide range of multi-core processes to optimize and load-balance both image processing and system operation (i.e.

  • Patent number: 10690816
    Abstract: Systems and methods reduce temperature induced drift effects on a liquid lens used in a vision system. A feedback loop receives a temperature value from a temperature sensor, and based on the received temperature value, controls a power to the heating element based on a difference between the measured temperature of the liquid lens and a predetermined control temperature to maintain the temperature value within a predetermined control temperature range to reduce the effects of drift. A processor can also control a bias signal applied to the lens or a lens actuator to control temperature variations and the associated induced drift effects. An image sharpness can also be determined over a series of images, alone or in combination with controlling the temperature of the liquid lens, to adjust a focal distance of the lens.

  • Patent number: 10482296
    Abstract: A code reader includes an image acquisition system to acquire a plurality of images. A sensor detects motion of the code reader, and a processor is operatively coupled to the image acquisition system and the sensor. The processor performs a plurality of steps including associating a first detected motion data with one of the plurality of acquired images; associating a second detected motion data with a subsequent one of the plurality of acquired images; attempting to decode the one of the plurality of acquired images; determining if the second detected motion data is preferred over the first detected motion data; and attempting to decode the subsequent one of the plurality of acquired images when the second detected motion data is preferred over the first detected motion data.
