Abstract: A modular electronic gaming machine is provided. The modular electronic gaming machine includes a structural core including a gaming controller and a plurality of coupling mechanisms including a first coupling mechanism. The first coupling mechanism comprises an electrical connector. The first coupling mechanism is configured to couple to a first peripheral device to provide electrical power and structural support to the first peripheral device. The first coupling mechanism is configured to releasably couple to the first peripheral device.

Abstract: In some examples, an electronic device can classify patches of touch data obtained by a touch screen as corresponding to intentional user inputs or not corresponding to intentional user inputs. The device can include a touch screen on a first side of housing of the device and a drive electrode on a second side of the housing of the device in some examples. In some examples, the drive electrode on the second side of the housing of the device can apply a signal to the body of the user and the device can classify patches of touch data including characteristics of this signal as corresponding to intentional touches provided by the user. The device can perform subsequent operations in response to intentional touches provided by the user and forgo performing operations in response to patches of touch data that do not correspond to intentional touches provided by the user.

Abstract: Systems and techniques for reducing distortions in magnetic resonance images. In one aspect, machine-implemented method for reducing image distortion in magnetic resonance imaging (MRI) includes receiving a first MRI image and a second MRI image, estimating displacements of voxels between the first MRI image and the second MRI image by minimizing a cost function expressing a cost of the displacements, reducing distortion in an MRI image using the estimated displacements, and making the MRI image having reduced distortion available. The first MRI image and the second MRI image were acquired using different gradient fields.

Abstract: Devices, systems, and techniques relate to detecting volumetric changes in imaged structures over time, including devices, systems and techniques that enable precise registration of structures (e.g., brain areas) after large or subtle deformations, allowing precise registration at small spatial scales with a low boundary contrast.
