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.

Abstract: This invention provides a module for a handheld device. The module includes an imager with optics and image acquisition/processing processors that provide high speed acquisition and handling of acquired image data—such as IDs. The acquired image data is processed by the device processor using a module application that resides within the device. The module includes indicators and/or alarms that can indicate success in reading an ID. A removable retaining component mounts within the module's base portion and carries the device. The retaining component (either a top cover and gasket or subframe) varies to accommodate different devices. The base portion includes appropriate ports to enable optical transmission to, for example, cameras and illuminators so that various native functions of the device can be employed as desired. The base portion also houses a battery and charging assembly e.g. and inductive charging unit. A grip handle/trigger is optionally provided to the base portion.

The acquired image data is processed by the device processor using a module application that resides within the device. The module includes indicators and/or alarms that can indicate success in reading an ID. A subframe removably mounts within the module's main body/frame and carries the device. The subframe can vary to accommodate different devices within a single main body/frame geometry. The main body/frame includes appropriate structures (ports) to enable optical transmission to, for example, cameras and illuminators so that various native functions of the device can be employed as desired. The main body/frame can also house a battery and charging assembly that supplies power to the device and allows charging through-for example and inductive charging unit.

Abstract: This invention provides 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.
