Abstract (en)

[origin: WO9841962A2] Various apparatus and methods for an actuator and display using one or more shape memory springs. A shape memory spring is heated and urges a pin to a first or extended position. The pin may be supported in the first position by a supporting mechanism. The shape memory spring is heated electrically, and in some embodiments under the control of a processor. The present invention may be used to display information provided in a user interface from a computer program, including text, numerical data, and graphical images.

[origin: WO9841962A2] A refreshable haptic display includes an actuator (35) using one or more shape memory springs (46). A shape memory spring (46) is heated and urges a pin (34) to a first or extended position. The pin (34) may be supported in the first position (34a) by a supporting mechanism. The shape memory spring (46) is heated electrically (48). The device may be used for haptic displays provided in a user interface from a software program and display controller.
