Abstract: A golf club has a first shaft coupled to a club head, a second shaft configured to slidably engage a portion of the first shaft, a grip coupled to the second shaft, and an adjustable length shaft assembly received by the second shaft and configured to allow a portion of the first shaft to slide in relation to the second shaft in a first configuration, and to restrict a portion of the first shaft from sliding in relation to the second shaft in a second configuration. The grip is restricted from rotation about the first shaft or the second shaft as the first shaft slides in relation to the second shaft.

Abstract: A data processing station and a method of operating a data processing station for processing and transmitting data between first and second devices. The data processing station comprises first and second interface units. The first interface unit has a multitude of states including a remote terminal state to receive data from and to transmit data to the first device, and a bus controller state to transmit data to the second device. The first interface unit also includes a first processor to generate an interrupt signal and to transmit the interrupt signal to the second interface unit-in response to predetermined events. The second interface unit is provided to receive data from and to transmit data to the second device, and this interface unit includes a second processor adapted to generate control signals and to transmit the control signals to the first interface unit to change the state thereof at predetermined times.
