  • Patent number: 10411646
    Abstract: A method for inspecting a solar cell and configured to inspect a peeling state of a three-dimensional pattern of the solar cell includes obliquely illuminating the three-dimensional pattern of the solar cell using a light beam. An image of the solar cell is normally captured. An intensity of the light beam is increased to increase a contrast between the three-dimensional pattern and a shadow of the three-dimensional pattern in the image and increase a contrast between an ink pattern of the solar cell and the shadow in the image to overexpose the ink pattern in the image. Determine if the three-dimensional pattern is peeling according to the shadow of the three-dimensional pattern in the image.

  • Patent number: 10086515
    Abstract: The invention is an in-process calibration system. It is not an open loop system or a closed loop system, but a hybrid system that retains both the low propensity for error of the closed loop system and the simplicity of the open loop system. The invention comprises a housing, one or more robots that move in up to three axes mounted to the housing, at least one sensor for each axis of the robots' movement, and a microcontroller. The sensors are fixed to the housing at known locations, and the microcontroller instructs end effectors of the robots through a sequence of moves that intermittently trigger the sensors. When the sensors are triggered, the microcontroller corrects the idealized location of the end effectors in the microcontroller's calculations to the actual location of the end effectors, which is, at the moment that the sensors are triggered, the known location of the sensors.

    Abstract: An agricultural communication system is provided that enables sensor-to-sensor link communications of peripheral farming devices (planters, fertilizer or pesticide applicators, etc.) so as to enhance diagnostics for locating system faults and blockages. The system also provides a means to operate with single-faults present with real-time diagnostics to the operator. The point-to-point communications also facilitates simplified installation by automatically determining the sensor addressing based on the physical connection of the sensors. Since the sensor-to-sensor daisy chain bus system is self-configuring there is no dependency on the sensor manufacturing data or sequential installation procedure to define the sensor address as required in other prior art systems. A dual power supply from each end of the looped bus with independent switching provides operation in the presence of single-faults, and a diagnostic mode combined with sensor power supply voltage measurements provides fault location.

    Abstract: An apparatus and method of operation for a high power broad band elongated thin beam laser annealing light source, which may comprise a gas discharge seed laser oscillator having a resonance cavity, providing a seed laser output pulse; a gas discharge amplifier laser amplifying the seed laser output pulse to provide an amplified seed laser pulse output; a divergence correcting multi-optical element optical assembly intermediate the seed laser and the amplifier laser. The divergence correcting optical assembly may adjust the size and/or shape of the seed laser output pulse within a discharge region of the amplifier laser in order to adjust an output parameter of the amplified seed laser pulse output. The divergence correcting optical assembly may comprise a telescope with an adjustable focus. The adjustable telescope may comprise an active feedback-controlled actuator based upon a sensed parameter of the amplified seed laser output from the amplifier laser.

  • Publication number: 20150083891
    Abstract: A touch-sensitive apparatus is configured to define a touch surface on a panel by propagating diverging energy beams (e.g. of radiation) across the touch surface inside the panel. Two rows (20A, 20B) of components (2, 3) of a first type that emits energy as a diverging beam and a second type that detects energy are functionally connected to the panel at opposite ends of the touch surface. The rows (20A, 20B) are defined by consecutive component blocks (B) that each contain only components (2, 3) of one type and are defined by type and number of included components. Each row (20A, 20B) comprises a respective sequence (S) of two component blocks (B) of different types and is defined by systematically repeating the sequence (S) along the respective opposite end.

    Abstract: A sensor comprises a detector defining a zone axis and adapted to receive a signal from within a zone around the zone axis and to generate an electrical signal, and a display module defining a display plane and adapted to display a pattern in the display plane based on the electrical signal, the display being oriented along an axis forming an angle with the zone axis such that the pattern is visible both from a direction parallel to the zone axis and from a direction perpendicular to the zone axis. In certain examples, the angle is about 45°, 40°-50°, 35°-55° or 25°-65°.

  • Patent number: 8975567
    Abstract: A coordinate detector includes a light output part, a light detection part, a first guide part, and a second guide part. The light output part emits light. The light detection part outputs a detection signal according to the amount of entering light. The light output part and the light detection part are provided in an area around a display part on a side closer to a first surface of the display part than to its second surface facing away from the first surface. The first guide part guides light emitted from the light output part toward a direction along the first surface. The second guide part guides, toward the light detection part, light exiting from the first guide part and passing over the first surface.

  • Publication number: 20150060641
    Abstract: An optical touch device defining a sensing area includes two scanning modules and a light detecting element. The scanning modules respectively disposed on terminals of a first side of the sensing area include light-emitting elements and reflective elements. The light-emitting element is used for emitting a detective light along a first pathway and the reflective element has a reflective surface for reflecting the detective light such that the detective light is emitted along a second pathway. There is an angle forming between the first side and the second pathway and the reflective surface changes a direction of the second pathway such that the detective light scans in the sensing area. The detective light has a first intensity and a second intensity, in which the first intensity is less than the second intensity. The light detecting element is used for receiving a detective light reflected by an object.

  • Patent number: 8921752
    Abstract: Moving-objects movable in a workspace, each includes an imaging unit with a two-dimensional light receiving surface; and a decoding processing unit. If light received by an imaging surface of the imaging unit is brightness-modulated information, the decoding processing unit decodes the received light to the information. If the information decoded by the decoding processing unit contains spatial position information of moving-objects other than a self-moving-object, the self-moving-object receives the light from light sources, has the decoding processing unit decode the light to acquire pieces of position information of the other moving-objects, thereby acquiring position information of the self-moving-object in the workspace from these pieces of position information.

    Abstract: A system for determining a location of an object on a planar surface includes a time-of-flight sensor having sensing elements that provide a field of view for the time-of-flight sensor. The system also includes a mirror attached to the shaft of a motor for reflecting the field of view of the time-of-flight sensor across the planar surface. The system also includes electrical circuitry configured to receive range images from the time-of-flight sensor as the field of view is swept across the planar surface and process the range images to identify the object in at least one of the range images. The electrical circuitry is also configured to calculate a location of the object on the planar surface relative to the motor based on an angle of the shaft associated with the at least one range image and based on a distance of the object from time-of-flight sensor.
