Abstract: A first device can send a first message comprising a device identifier. A second device can receive the first message. The second device can send the device identifier and first metadata to a server, wherein the first metadata is associated with the second device. The server can receive the device identifier and the first metadata. The server can further send the device identifier and first metadata to a third device.

Abstract: A first computing system can receive a proximity message from a source device, the proximity message comprising a device identifier and a network address. The first computing system can further determine that the first computing system is within a particular distance of the source device based, at least in part, on the proximity message. In response, the first computing system can send a proximity notification to a second computing system. The proximity notification can comprise the device identifier and a user identifier. The second computing system can receive the proximity notification. The second computing system can further determine user metadata associated with the user identifier. The second computing system can further determine a third computing system based, at least in part, on a mapping between the device identifier and a computing system identifier. The second computing system can further send the user metadata to the third computing system.

Abstract: A device can receive a proximity message comprising a base station identifier and a network address. The device can determine that the device is within a particular distance of a base station associated with the base station identifier based, at least in part, on the proximity message. In response to a determination that the device is within the particular distance of the base station, the device can display an actionable notification. The device can further determine that an action associated with the actionable notification has been performed. In response to a determination that the action has been performed, the device can send a proximity notification to a server identified by the network address, wherein the proximity notification comprises the base station identifier.

Abstract: Magnetic resonance tomography apparatus has a device whose spatial orientation can be modified in order to define a spatial orientation of a tomogram, and whose spatial position can be modified in order to define a spatial position of the tomogram, these definitions taking place before the exposure of a tomogram or acting on an existing three-dimensional image data set. The device has a planar stamped part in the form of a plate, or a display surface or has an oblong stamped part, the device is not fastened to the apparatus or at least, is not fastened to it fixedly, or is fastened to it via a carrier device, and the orientation and position of the device is acquired by position sensors.
