Abstract: This disclosure is directed to a smart playable flying disc and methods for determining associated motion parameters. The playable device may capture and transmit sensor data including motion data to a computing device. Motion parameters can be determined based on the sensor data. For example, an initial velocity of the playable device can be determined based on a throw duration and a maximum acceleration. Machine learning algorithms can determine updated parameters based on learned parameters. The playable device can include rapid charging circuits to receive power from a remote charger. Sensor data may also be interpreted by the computing device as gestures for interacting with the computing device or for presentation during gameplay. The computing device can capture image data of the playable device and identify the playable device and annotate image data based on the sensor data from the playable device.

Abstract: A method and a device for exchanging data in messages between at least two stations connected by a bus system. The messages contain the data being transmitted by the stations over the bus system. Each message contains an identifier characterizing the data contained therein. Each station decides on the basis of the identifier whether to receive the message. The messages are controlled in time by a first station. The first station repeatedly transmits a reference message over the bus in at least one specifiable time interval. The time interval is subdivided into time windows of a specifiable length, the messages being transmitted in the time windows.

Abstract: A method for exchanging data in messages between at least two users connected by a bus system, where each of the at least two users includes a predefinable and/or ascertainable timing mark, includes causing the at least two users to transmit, via the bus system, messages including the data. The method also includes causing a first user, in a function as timer, to control the messages as a function of time in such a way that it repeatedly transmits a reference message, which contains time information of the first user, via the bus at a specifiable time interval. Further, if the timing mark of the second user is reached without a reference message of the first user reaching the second user, the second user is caused to take over the function of timer by transmitting its own reference message with its own time information via the bus system.

Abstract: A method for exchanging data in messages between at least two stations connected via a bus system. The messages contain the data being transmitted by the stations over the bus system, and the messages are controlled over time by a first station in such a manner that the first station repeatedly transmits a reference message containing time information of the first station over the bus system at least one specifiable time interval. The time interval is subdivided as a basic cycle into time windows of specifiable length, and the messages are transmitted in the time windows. When data is exchanged, a pause period of variable duration is provided at the end of at least one basic cycle, by which a time change of the beginning of the basic cycle is corrected by adaptation of the duration of the pause period.

Abstract: A bus system includes at least two data buses, the first data bus having a first number of users and the second data bus having a second number of users. At least two TTCAN buses, which are interlinked by users connected simultaneously to both TTCAN buses, are used as the data buses. Fewer users than the sum of the number of users of the first TTCAN bus and the number of users of the second TTCAN bus are connected to the two TTCAN buses at the same time. A generating arrangement is included to generate a scalable fault tolerance in the bus system as a function of the number of users connected to the at least two TTCAN buses at the same time.
