Abstract:

The present disclosure relates to a miniature precision clamping assembly driven by a shape memory alloy actuator wire (SMA wire) which may be employed within a braking or clutch system. The clamping assembly includes a first clamping element, a second clamping element and an SMA wire connected to the first and second clamping elements by being interwoven through a plurality of pressure amplifiers located on the exterior surfaces of the first and second clamping elements. Both the first and second clamping elements are configured to be positioned about a rotatable shaft and move in translation to the shaft via a transition action of the SMA wire between a clamping and releasing position. By energizing the SMA wire a contracting or compressing action is generated thereby causing the first and second clamping elements to move into engagement with the one shaft for inhibiting rotational movement.

Abstract:

A vehicle entertainment system is for use with wireless headphones, with each wireless headphone being operable via a respective paired wireless connection. The vehicle entertainment system may include video entertainment displays for a vehicle, and a controller for the vehicle. The controller may be configured to establish respective paired wireless connections with the wireless headphones, and provide selectable access to a plurality of different audio/video (A/V) entertainment content streams. Each of the A/V entertainment content streams may include a respective video entertainment stream and an associated audio entertainment stream. The controller may be further configured to send selected video entertainment content streams for viewing at the video entertainment displays, and send selected audio entertainment content streams over the respective paired wireless connections for hearing at the wireless headphones.
