Abstract: A variable-pitch vertical axis wind turbine comprises a hub supported for rotation about a central axis and a blade pivotally mounted to the hub so as to permit relative rotation between the blade and the hub. The blade and the hub define a pitch angle therebetween. The wind turbine comprises a mechanism configured to produce reciprocating motion during rotation of the hub about the central axis. The wind turbine comprises a linkage configured to transfer the reciprocating motion produced by the mechanism to the blade so as to vary the pitch angle.

Abstract: A mounting mechanism for a computer interface device for use in a vehicle. The mounting mechanism provides for the interface device to be mounted onto a control panel of the vehicle so that it is accessible and visible to an occupant of the vehicle in an in-use position. The mounting mechanism provides for the interface device to be rotated between the in-use position and a folded position that mitigates interference with the accessibility and visibility of the control panel. The mounting mechanism comprises device brackets for attachment to the computer interface device, mounting brackets for attachment to the control panel, resistance elements for pivotally connecting the device brackets to the mounting brackets and for resisting the rotation of the device bracket relative to the mounting brackets, and up-stops and down-stops for limiting the rotation of the computer interface device to define the in-use and folded positions respectively.
