Abstract
Official abstract text for this publication.
An electrically controlled switching device includes a support, a first contact coupled to the support, a second contact coupled to the support, an SMA element operably connected with the second contact, a sensor positioned on or adjacent to the SMA element, and a controller in communication with the sensor. The SMA element is configured to transform between a first shape and a different second shape responsive to an electrical pulse heating the SMA element to a transformation temperature. The sensor is configured to detect a detected temperature of the SMA element. The controller is configured to control the electrical pulse heating the SMA element. The controller receives signals from the sensor indicative of the detected temperature of the SMA element.
First claim
Opening claim text (preview).
The invention claimed is: 1. An electrically controlled switching device comprising: a support; a first contact coupled to the support; a second contact coupled to the support; a shape memory alloy (SMA) element operably connected with the second contact and configured to transform between a first shape and a different second shape responsive to an electrical pulse heating the SMA element to a transformation temperature; a sensor positioned on or adjacent to the SMA elemen…
