Patent number: 6555201Abstract: An electromechanical device includes a first frame having a first aperture therein, a second frame suspended in the first frame wherein the second frame has a second aperture therein, and a plate suspended in the second aperture. A first pair of beams support the second frame along a first axis relative to the first frame so that the second frame rotates about the first axis. A second pair of beams supports the plate along a second axis relative to the second frame so that the plate rotates about the second axis relative to the frame. The first and second axes preferably intersect at a 90° angle. A first actuator provides mechanical force for rotating the second frame relative to the first frame about the first axis. A second actuator provides mechanical force for rotating the plate relative to the second frame about the second axis. Accordingly, the plate can be independently rotated relative to the first axis and the second axis. Related methods are also disclosed.Type: GrantFiled: May 15, 2000Date of Patent: April 29, 2003Assignee: MCNCInventors: Vijayakumar R. Dhuler, David A. Koester, Mark D. Walters, Karen W. Markus

Patent number: 6406781Abstract: An adhesive article adapted for removable adhesive bonding on a support surface, such as a wall, includes a base member and a stretch release adhesive tape strip. The adhesive tape strip is a sequential release-type adhesive strip having a non-adhesive end portion which allows the base member to release from the adhesive strip during the removal process while the adhesive strip remains adhered to the support surface, therefore reducing the incidence of unwanted catapulting. To prevent relative movement between the base member and the adhesive strip during the removal process and therefore increase the likelihood of successful controlled sequential release of the base member, the base member includes a stabilizer arranged to abut the adhesive strip if the base member shifts as the adhesive strip is stretched during removal. The stabilizer can be a generally rigid projection or a compressible stop member which extends outwardly from the end of the base member adjacent the end of the adhesive strip.Type: GrantFiled: June 23, 1998Date of Patent: June 18, 2002Assignee: 3M Innovative Properties CompanyInventor: Michael D. Hamerski
