  • Publication number: 20140202628
    Abstract: A multi-layer, super-planar structure can be formed from distinctly patterned layers. The layers in the structure can include at least one rigid layer and at least one flexible layer; the rigid layer includes a plurality of rigid segments, and the flexible layer can extend between the rigid segments to serve as a joint. The layers are then stacked and bonded at selected locations to form a laminate structure with inter-layer bonds, and the laminate structure is flexed at the flexible layer between rigid segments to produce an expanded three-dimensional structure, wherein the layers are joined at the selected bonding locations and separated at other locations.

  • Publication number: 20120292438
    Abstract: A passively torque-balanced device includes (a) a frame; (b) a drivetrain including a drive actuator mounted to the frame and configured for reciprocating displacement, an input platform configured for displacement by the drive actuator, a plurality of rigid links, including a proximate link and remote links, wherein the rigid links are collectively mounted to the frame, and a plurality of joints joining the rigid links and providing a plurality of non-fully actuated degrees of freedom for displacement of the rigid links, the plurality of joints including a fulcrum joint that is joined both to the input platform and to the proximate rigid link; and (c) at least two end effectors respectively coupled with the remote links and configured for displacement without full actuation.

  • Publication number: 20110043788
    Abstract: A fully integrated portable screening system includes a main housing and a contact pad. The contact pad is removably positioned in the main housing and covered by at least one sample sheet. The contact pad is preferably constituted by a cylindrical baton which carries a roll of sample collection sheets. A test subject interacts with the contact pad, leaving a trace sample on the sample collection sheet. The contact pad is then placed within the main housing and the trace sample is exposed to a test medium designed to interact with a specific analyte of interest potentially present in the trace sample. After exposure to the test medium, the sample sheet is subjected to a testing mechanism which exposes any interaction between the test medium and the analyte of interest to produce a test result.
