Patent number: 11918331Abstract: A movement detection device includes a signal transmission device configured to transmit a radar signal transmission toward a target area and to receive reflected radar signals, and a signal analysis device configured to analyze the reflected radar signals to detect a movement in the target area that is indicative of micro-shivering. In response to detecting the micro-shivering, the movement detection device generates an alarm.Type: GrantFiled: November 24, 2020Date of Patent: March 5, 2024Assignee: Hill-Rom Services, Inc.Inventors: Steven D. Baker, Jennifer Bergstrom, Heinz-Hermann Dalbert, Brandon P. Fisk, Yongji Fu, Michael S. Hood, Charles A. Lachenbruch, John A. Lane, Kenzi L. Mudge, Matthew O'Neal, Frank E. Sauser, Douglas A. Seim, Gregory J. Shannon

Patent number: 6900510Abstract: A Microelectromechanical (MEMS) device and method of fabrication that can minimize derailing of an actuable element of the MEMS device during fabrication can include a MEMS actuator to selectively generate displacement forces to displace an actuable element along a path between sidewalls of a channel. The sidewalls can have stops formed therein that can interact with surfaces on the actuable element to limit displacement of the actuable element during fabrication. One of the sidewalls can be indented to form the stops and the actuable element can have an arm portion that extends between the stops. The sidewalls can be offset to form the stops on spaced apart faces on opposite sides of the channel and the actuable element can be offset between the spaced apart faces to form offset faces in an opposing relationship with the spaced apart faces on the sidewalls. In addition, the actuable element and the sidewalls may be so shaped as to maintain a generally constant width between them.Type: GrantFiled: December 4, 2002Date of Patent: May 31, 2005Assignees: Advanced Microsensors, Furukawa America, Inc.Inventors: Hirokazu Tamura, Matthew J. Neal, Alan L. Sidman, Jiang Zhe

Patent number: 6858911Abstract: A Microelectromechanical (MEMS) device that can minimize the effects of fabrication tolerances on the operation of the device can include a MEMS electromagnetic actuator to selectively generate displacement forces to displace an actuable element along a path. A cantilever can apply an opposing force to the actuable element to control the amount of displacement. Coil ends of the actuator can be shaped to vary a gap distance between the coil ends, and/or the magnetic portion of the actuable element may be shaped, so as to vary the force applied to the actuable element along the displacement axis. One or more pins located in the deflection path of the cantilever can contact the cantilever at one or more points so as to change the bending resistance of the cantilever. The cross-section of the cantilever can also be varied along its length so as to change the bending resistance of the cantilever.Type: GrantFiled: December 4, 2002Date of Patent: February 22, 2005Assignees: Advanced Micriosensors, Furukawa American, Inc.Inventors: Hirokazu Tamura, Matthew J.

Patent number: 6812055Abstract: Microelectromechanical (MEMS) devices that use MEMS electromagnetic actuators to selectively generate displacement forces are disclosed herein. According to one exemplary embodiment disclosed herein, a MEMS device may include a substrate having a surface, an actuable element at least partially formed from the substrate, and an electromagnetic actuator disposed on the substrate for selectively applying a first force to the actuable element to displace the actuable element along a path. The actuable element may have a base and an arm coupled to the base. The base may include a portion comprised of a magnetic material. The electromagnetic actuator may comprise an electrically conductive coil, and the path of the actuable element may pass through a coil gap in the coil. The electromagnetic actuator may also comprise a magnetic core about which the electrically conductive coil may be wound.Type: GrantFiled: December 18, 2003Date of Patent: November 2, 2004Assignees: Advanced Microsensors, Furukawa America, Inc.Inventors: Hirokazu Tamura, Matthew J.
