Patent number: 8907376Abstract: A stretchable electronic circuit that includes a stretchable base substrate having a plurality of stretchable conductors formed onto a surface thereof, with both the stretchable base substrate and conductors being bendable together about two orthogonal axes. The stretchable circuit also includes a stretchable sensor layer attached to the base substrate with a cavity formed therein which has a contact point exposing one of the plurality of stretchable conductors. The stretchable electronic circuit further includes a surface mount device (SMD) package with a conductor contact protrusion installed into the cavity, and wherein a substantially constant electrical connection is established between the conductor contact protrusion and the stretchable conductor at the contact point by tensile forces interacting between the stretchable base substrate and the stretchable sensor layer.Type: GrantFiled: November 8, 2012Date of Patent: December 9, 2014Assignee: University of Utah Research FoundationInventors: Stephen Mascaro, Debra Mascaro, Jumana Abu-Khalaf, Jungwoo Park

Publication number: 20080091121Abstract: A system for detecting an amount of force applied to a finger where the back upper portion of the finger is illuminated by light. The system includes intrasubject and intersubject registration. Another embodiment relates to using linear discriminant analysis to generate a fingertip force model and obtain a force measurement. In other embodiments, the system is used to mimic the input of a mouse, a track/touch pad, a keyboard device, or control a robot. In other embodiments, the system is used to assist in physical therapy, medical diagnosis, medical studies, or contact measurement.Type: ApplicationFiled: March 20, 2007Publication date: April 17, 2008Inventors: Yu Sun, John Hollerbach, Stephen Mascaro

Patent number: 6388247Abstract: A device for detecting the posture a finger or forces applied to a finger, the finger having a fingernail illuminated by light, comprises at least one photodetector for measuring a change in light reflected by an area of the finger beneath the fingernail in response to the posture of the finger or forces applied to the finger. The photodetector provides a signal corresponding to the change in light reflected. The device also includes a processor for receiving the signal and determining whether the change corresponds to a specified condition. The photodetector may be enclosed in a housing and coupled to the fingernail.Type: GrantFiled: March 9, 2001Date of Patent: May 14, 2002Assignee: Massachusetts Institute of TechnologyInventors: Haruhiko H. Asada, Stephen Mascaro

Patent number: 6135228Abstract: A hybrid personal vehicle capable of holonomic omni-directional self-locomotion. The vehicle may be programmed to navigate to a specified location in a crowded household environment. Additionally, sensors are provided for accurate docking and tight mating with fixtures such as a toilet or bed. A controller determines a docking trajectory to a specified fixture and behaves with arbitrary stiffness in each degree of freedom about a determined center of compliance.Type: GrantFiled: April 21, 1997Date of Patent: October 24, 2000Assignee: Massachusetts Institute of TechnologyInventors: Haruhiko H. Asada, Stephen Mascaro, Joseph Spano
