Abstract: Systems, methods, and computer program products for image recognition in which instructions are executable by a processor to dynamically generate simulated documents and corresponding images, which are then used to train a fully convolutional neural network. A plurality of document components are provided, and the processor selects subsets of the document components. The document components in each subset are used to dynamically generate a corresponding simulated document and a simulated document image. The convolutional neural network processes the simulated document image to produce a recognition output. Information corresponding to the document components from which the image was generated is used as an expected output. The recognition output and expected output are compared, and weights of the convolutional neural network are adjusted based on the differences between them.

Abstract: An active display can be used in a theatre with reduced screen-door effect. For example, the active display can have a structure, such as a diffuser structure, or a diffuser and mask structure, that can have, or appear to have, transmissive areas and opaque areas to reduce the audience from detecting gaps or other non-light sources in the active display. The active display may additionally or alternatively have audio ports to allow sound to pass through the active display and appear to the audience as if the sound is coming from the active display.

Abstract: An active display (102) can be used in a theatre environment (100) in which content to be displayed by the active display (102) can be delivered wirelessly using emitters (118). The active display (102) can include tiles (104a-104d) with detectors (106a-106d) that can detect the wireless signals. The active display (102) can include circuitry that can interpret instructions from the wireless signals for controlling the output (108a-108d) of pixels on the tiles.

Abstract: Screen vibration systems are provided that can vibrate theatre screens while reducing the presence of image artifacts that may otherwise be visible as result of vibrating the screen. In one example of a screen vibration system, the system includes a screen, a permanent magnet mounted to the screen, and a magnetic source positioned with respect to the permanent magnet. The screen is moveable in response to a changing magnetic field from the magnetic source.

Abstract: A cinema screen can be vibrated by a screen vibrator assembly. A screen vibrator assembly can include a vibrator, a mount bracket, and an isolation device. The vibrator can be positioned to generate a vibration for vibrating a cinema screen. The mount bracket is configured to be coupled to a screen support structure of the cinema screen. The isolation device is configured to couple the vibrator to the mount bracket to isolate the mount bracket from the vibration.

Abstract: A screen can be vibrated by vibrators that are drivable by signals. Each vibrator can be adjacent in position to other vibrators that are drivable by different types of drive signals than a drive signal associated with the vibrator. The number of drive signals can be equal to or less than the number of vibrators. A vibrator assembly for a vibrator can include a baffle and a transducer that couples to the baffle. The transducer can vibrate at least a portion of the screen. The vibrating screen can be monitored by a sensor and an analyzer unit that can analyze image speckle and screen displacement artifacts in captured images of images projected onto the screen and output results of the analysis.

Abstract: Screen vibration systems are provided that can vibrate theatre screens using acoustical, electromagnetic, or another type of energy while reducing the presence of image artifacts that may otherwise be visible as result of vibrating the screen. In one example of a screen vibration system, the system includes a screen, a permanent magnet mounted to the screen, and a magnetic source positioned with respect to the permanent magnet and uncoupled from the screen. The screen is moveable in response to a changing magnetic field from the magnetic source.

Abstract: A loudspeaker cabinet having at least one side wall defining a side wall perimeter; a front wall mounted to the at least one side wall along the side wall perimeter, the front wall having a front surface; wherein a central area of the front surface is positioned within the side wall perimeter, an extended area of the front surface extends beyond the side wall perimeter, and a portion of the extended area is configured to provide a gradual transition to open free space.

Abstract: A shim for a compression mold for manufacturing a component from reinforced plastic, typically from SMC, comprising a fixed molding element, a mobile molding element, and a mobile shim that can be moved by an actuator. The mobile shim comprises a conventional part made of steel but also a part made of a high expansion material with a mean coefficient of expansion that is high enough that its own expansion at the molding temperature places the shim in compression against the molding element and seals against this element, thus eliminating flash on the molded part. This material is advantageously a polyetheretherketone, or PEEK. A mold comprising this shim and a compression molding method are also disclosed.
