Abstract: A sensor apparatus is provided. Multiple opposite and self-powered sensors are provided in another aspect of the present apparatus. A further aspect employs a sensor apparatus including a first pair of flexible piezoelectric sensors attached to opposite sides of an exterior surface of a workpiece and at least a second pair of flexible piezoelectric sensors attached to opposite sides of the exterior surface of the workpiece. Another aspect of the present apparatus uses pairs of thin film piezoelectric sensors which are configured to detect bending curvature of a workpiece in at least two dimensions by sending voltage output signals from both of the sensors of a first pair and/or both of the sensors of at least a second pair to a controller and/or electrical circuit.

Abstract: A method includes obtaining, by a processing device, data indicative of locations of defects of a substrate. The method further includes generating an image indicating the locations of the defects. The method further includes providing the image indicating the locations of the defects to a trained machine learning model. The method further includes obtaining, as output from the trained machine learning model, a classification of the locations of the defects. The method further includes performing a corrective action in view of the output from the trained machine learning model.

Abstract: A bean roasting system includes a roasting chamber, a blower, a variable diverter and a controller. The roasting chamber, the blower and the variable diverter each is disposed at least partially within a recirculating gas flow path. The blower is configured to provide a flow stream of gas through the recirculating gas flow path. The variable diverter is configured to split the gas flow path into at least two flow paths including a treated flow path and a bypass flow path. The treated flow path includes a series arrangement of a gas heater and a catalytic converter. The variable diverter is configured to control a percentage of a flow stream of gas that is diverted into the bypass flow path. The controller is configured to activate different predetermined operating modes for the bean roasting system by controlling a state of the variable diverter and a state of the heater.

Abstract: A touch sensor for a touch system includes a housing having a light sensing window, a light blocking section, and a reference window, the light sensing window and the reference window configured to allow light to pass therethrough, the light blocking section configured to prohibit light from passing therethrough, a rotating assembly disposed within the housing, and a light sensor. The rotating assembly is configured to transmit light received from the light sensing window and the reference window to the light sensor, and the light sensor is configured to output a signal that is utilized to identify an angular location of a touch. A touch system including such touch sensors is also described herein.

Abstract: A color correction filtering system filters color video data by compensating for non-linearities and color characteristics specific to a color monitor. Color video data is received by the system, for example through a web browser, and in an accelerated manner passed through a pre-calculated gamut-shifting array. The color correction filtering system gamma decompensates incoming color video data referenced to a non-linear color space through use of a linearization filter. The gamut-shifting array may contain pre-calculated compensation values stored in a plurality of look-up tables. A non-linearization filter is applied to the gamut-shifted color video data to produce color video data compensated for non-linearities specific to the color monitor.

Abstract: A computer system is disclosed for providing rapid access to preconfigured Internet sites. The system includes a keyboard or similar input device having switches which are closed to produce unique Internet access signals. A signal processing circuit places the computer system in communication with corresponding unique Internet sites in response to the Internet access signals. Application software is also launched as required by the particular access switch, such as for electronic commerce or electronic messaging. If the system is not yet logged onto the network, a log-on routine is executed in response to the access signals. A user may actuate the switches to rapidly access desired Internet sites and to perform operations at the sites without the need to navigate through a series of on-screen windows or menus.

Abstract: The invention relates to the art of corneal topography. More specifically, the invention provides many methods and apparatuses for advancing the ease and accuracy of corneal topography. In addition to a front-view camera, one embodiment provides a side (temporal) view camera for viewing the cornea or other reflective surface. The side-view camera may capture a true image of the cornea as well as a reflected placido pattern. The information contained in these images provides capability to automatically find the apex, location of the limbus, vertical profile and curvature out to the limbus. These abilities lead to improved methods for autocalibration and autopositioning as well as other advantages in the field of corneal mapping.
