Embodiments include measuring motion characteristics of the workpiece through the placement process. Since the component is placed on the workpiece with some force to ensure proper adhesion to the workpiece, some deflection of the workpiece is expected during the placement cycle. The placement force is adjusted to ensure that the component is safely placed into the solder paste or adhesive. Placement force is adjusted through a number of characteristics including: choice of spring tension in the nozzle; the length of the nozzle and the amount of over-travel into the board; the rigidity of the board and design; and the placement of the board support mechanisms. With proper adjustment of these characteristics and parameters, high quality placements onto the workpiece can be ensured.

A system for digital image recognition which combines sparse correlation with image pyramiding to reduce the number of pixels used in correlation provides effective recognition of a reference image template without exhaustive correlation of all pixels in the reference image template. An optimal sparse pixel set is selected from the pixels of the reference image template by correlating the reference image template against a search image scene which is to be searched. Such a sparse pixel set includes those pixels which are optimal in defining the correlation sensitive features of the reference image template. By terminating the accumulation of sparse pixels at an optimal point, performance is maximized without compromising accuracy of recognition. The resultant optimal sparse pixel set is then correlated against the pixels in the search image scene through a series of transformations to find a match of the reference image template within the search image scene.

A method for decoration of paper or plastic sheeting and other substrates, involving a novel technique for coating and embossing the substrate. The paper or plastic sheeting is supplied with a coating of thermosensitive material, as by extrusion. The coated sheet is heated to adequately soften the coating, such as by use of a heated cylinder, and remote heat sources such as infrared heaters. The softened sheet surface is then decorated using an embossing member, to provide a diffraction pattern or hologram. Use of an embossment pattern of lesser depth than the surface roughness of the sheet before embossing provides attractive decorative patterns.

An autonomous mobile robot includes a robot body, a drive system, a sensor system, and a controller. The drive system supports the robot body and maneuvers the robot over a floor surface. The sensor system includes an inertial measurement unit for measuring a pose of the robot and issues a sensor signal including data having information regarding a pose of the robot. The controller communicates with the drive and sensor systems and executes a behavior system. The behavior system receives the sensor signal from the sensor system and executes a behavior. The behavior system executes an anti-stasis behavior in response to sensor signals indicating that the robot is constrained to evaluate a state of constraint. In addition, the behavior system executes an anti-tilt behavior in response to sensor signals indicating that the robot is tilted with respect to a direction of gravity to evaluate a state of tilt.
