摘要:
A reference image of an area of a print media is captured at approximately a first time by an image acquisition system. A first application of ink is applied onto the print media area by a printing assembly at the first time. A comparison image of the print media area is captured at a second time by the image acquisition system subsequent to the first application of ink onto the print media area. The reference image and the comparison image are processed to determine a relative displacement of a feature pattern on the print media between approximately the first time and the second time. A second application of ink from the printing assembly onto the print media is adjusted based on the determination.

A first device has a micrometer-scale or smaller first structure and is flexibly coupled to a first substrate. A second device has a micrometer-scale or smaller second structure and is coupled to a second substrate. At least one actuator displaces at least one of the first and second devices relative to the other in response to a control signal. The control signal is generated by a controller to align the first and second structures and to control the at least one actuator to connect the displaced first and second devices.

In embodiments of a touch-scrolling pad for computer input devices, a touch sensor strip detects touch contacts on a touch-scrolling pad that is implemented for vertical scrolling input and horizontal scrolling input. A selectable button positioned proximate below the touch sensor strip can be selected by an actuation depress input to the touch-scrolling pad. The touch-scrolling pad includes programmed instructions in firmware implemented to determine that a touch contact is one of a vertical scrolling input, a horizontal scrolling input, or the actuation depress input to actuate the selectable button. The touch-scrolling pad also includes a haptic system that generates haptic feedback responsive to either of the vertical scrolling input or the horizontal scrolling input.

Using an imaging system in relation to a plurality of material layers is described, the material layers being separated by a distance greater than a depth of field of the imaging system. A focal plane of the imaging system and a first of the plurality of material layers are brought into correspondence. A first image including at least a portion of the first material layer having a first feature of interest thereon is stored. The focal plane of the imaging system and a second of the plurality of material layers are brought into correspondence. A second image including at least a portion of the second material layer having a second feature of interest thereon is acquired. The first and second images are processed for automatic computation of an alignment measurement between the first and second features of interest.

A displacement estimation system including a data acquisition system and a processing system is provided. The data acquisition system is configured to capture a first frame from a first substrate including a first pattern and a second substrate including a second pattern at a first time and capture a second frame from a third substrate including a third pattern and a fourth substrate including a fourth pattern at a second time subsequent to the first time. The first pattern and the third pattern are substantially identical, and the second pattern and the fourth pattern are substantially identical. The processing system is configured to calculate a first displacement between the first pattern and the third pattern using the first frame and the second frame and calculate a second displacement between the second pattern and the fourth pattern using the first frame and the second frame.

Determining a displacement of a substantially rigid item relative to a frame of reference between a first time and a second time is described. At the first time, a first set of pointwise measurements of a physical property of the item taken at a plurality of fixed locations relative to the frame of reference is acquired. At the second time, a second set of pointwise measurements of the physical property taken at the plurality of fixed locations is acquired. A first matrix derived from the first set of pointwise measurements is compared to a second matrix derived from the second set of pointwise measurements to determine the displacement.
摘要:
Determining a dimensional change in a surface of an object is described. At a first time, a first image of the surface is acquired at a first spatial window thereon having a first known position relative to a frame of reference. At a second time, a second image of the surface is acquired at a second spatial window thereon having a second known position relative to the frame of reference. The first image and the second image are processed according to an image displacement sensing algorithm to determine a relative translation of a first point on the surface between the first and second times. The relative translation of the first point, the first known position, and the second known position are used to determine the dimensional change in the surface between the first and second times.
摘要:
A contact lithography alignment system and method use nanoscale displacement sensing and estimation (nDSE) to maintain an alignment and compensate for a disturbance of one or more objects during contact lithography. A method of maintaining an alignment includes establishing an initial alignment of one or more objects and employing nDSE-based feedback control of relative positions of more or more of the objects to maintain the alignment during contact lithography. A method of disturbance compensation includes acquiring a first image, acquiring a second image, estimating an alignment error using nDSE applied to the first and second image, and adjusting a relative position to reduce the alignment error. A contact lithography system includes an optical sensor, a feedback processor providing nDSE and a position controller that adjusts relative positions of one or more objects to reduce an alignment error determined using the nDSE.
