Abstract: An aspect of the invention provides a method of synchronising a first clock of a first device and a second clock of a second device comprising. The method includes transmitting 302 a dummy packet from the second device to the first device over a wireless network; determining 304 a time D2 on the second clock associated to a time that the second device initiates transmission of the dummy packet; determining 306 a time D1 on the first clock associated to the time that the first device receives transmission of the dummy packet; transmitting 308 a value of D2 from the second device to the first device; and applying 310 a correction to the first clock based at least partly on a difference between D1 and D2.

Abstract: A trampoline as a controller or an input device for playing games, including a frame having a flexible mat divided into input zones and one or more neutral zones, a sensor arrangement to detect activity on the flexible mat, a controller configured to determine the bounce location and bounce zone of the activity and provide this information to a feedback generator for playing games on the trampoline, such that a user uses the trampoline to play games by jumping on the input and neutral zones.

Abstract: A trampoline comprises multiple movement sensors associated with one or more parts of the trampoline which move when the trampoline is bounced on by a user such as the trampoline mat, and an electrical wiring loom which connects to the movement sensors to a controller or a common connector at another end of the wiring loom. Various sensor mount and wiring loom options are described.

Abstract: A method of interpreting an activity of a person on a flexible mat of a trampoline, the method comprising: at least one processor determining a bounce instruction for the person on the flexible mat; determining a first bounce location of the person on the flexible mat; determining a second bounce location of the person on the flexible mat; determining a lead time boundary interval; responsive to determining a time of display of the bounce instruction prior to the lead time boundary interval, the at least one processor comparing the second bounce location with the bounce instruction; and responsive to determining a time of display of the bounce instruction within the lead time boundary interval, the at least one processor determining a third bounce location of the person on the flexible mat and comparing the third bounce location with the bounce instruction.

Abstract: A method of measuring an activity of a person/object on a flexible mat of a trampoline, comprising: determining a mat deformation signal based at least on measurements from a sensor arrangement comprising at least one sensor and defining a coordinate space for the mat; the or each sensor being configured to measure a value corresponding to a deformation of the mat as the person/object moves on the mat; wherein, the value measured by die or each sensor corresponds to a proximity of the person/object to the sensor; determining a bounce coordinate in the coordinate spate based at least on the mat deformation signal; and determining a bounce location of the person/object on the mat based at least on the bounce coordinate in the coordinate space. Also provided is a trampoline configured to indicate an activity of a person/object on the mat and an interactive apparatus that includes the trampoline.
