Publication number: 20230050270Abstract: Introduced here are containers designed to promote compliance with regimens for administering the medications stored therein. These containers can facilitate the conveyance of information related to a regimen through the use of a non-written medium. A container may include one or more display elements configured to emit/reflect light to indicate when medication stored in the container should be administered. An example of a display element is a light-emitting diode (LED). Emittance/reflectance of the light by the display element(s) may be governed by a different clock signal than the clock signal used to determine whether doses of medication are due to be administered.Type: ApplicationFiled: January 15, 2021Publication date: February 16, 2023Inventors: Jonathan Grossman, Jasper L. Steyn

Patent number: 9235046Abstract: This disclosure provides systems, methods and apparatus for providing relatively thinner and less stiff compliant beams for a shutter assembly. A protective coating is deposited and patterned over the shutter assembly before it is released from a sacrificial mold over which the shutter assembly is formed. Because some primary surfaces of the compliant beams are in contact with the sacrificial mold, these primary surfaces are not coated with the protective coating. Therefore, when the shutter assembly is finally released, the resulting compliant beams are relatively thinner and less stiff providing a reduction in an actuation voltage used to operate the shutter assembly. In some instances, the protective coating is patterned into discontinuous segments before release.Type: GrantFiled: January 30, 2013Date of Patent: January 12, 2016Assignee: Pixtronix, Inc.Inventors: Javier Villarreal, Timothy J. Brosnihan, Jasper L. Steyn, Richard S. Payne, Stephen R. Lewis

Patent number: 9202821Abstract: This disclosure provides systems, methods and apparatus for forming electromechanical systems (EMS) displays where the area of a substrate occupied by a pixel circuit can be reduced if portions of the pixel circuit can be built in three dimensions. In some aspects, certain EMS displays can incorporate structures that are substantially normal to the surface of a substrate. Incorporating circuit components, such as transistors, into such structures, can reduce the area they occupy within the plane of the substrate. In some aspects, the components of a transistor can be fabricated directly into a MEMS anchor that supports a light modulator or a portion of an actuator over the substrate. In some other aspects, the transistor can be fabricated on one or more sidewalls of any MEMS structure.Type: GrantFiled: October 23, 2013Date of Patent: December 1, 2015Assignee: Pixtronix, Inc.Inventors: Patrick F. Brinkley, Wilhelmus A. De Groot, Jasper L. Steyn, Elif Selin Mungan

Patent number: 9201236Abstract: A display apparatus includes a plurality of electromechanical systems (EMS) devices disposed on a first surface defined by a face of a substrate. Each EMS device includes a component which is movable in a plane that is substantially parallel to the first surface. The apparatus also includes a second surface positioned proximate to the substrate such that the plurality of EMS devices are located between the first surface and the second surface. In addition, each EMS device includes at least one anti-stiction projection positioned between the movable component and the second surface.Type: GrantFiled: November 27, 2012Date of Patent: December 1, 2015Assignee: Pixtronix, Inc.Inventors: Joyce H. Wu, Jasper L. Steyn, Eugene E. Fike, Cait Ni Chleirigh, Timothy Brosnihan, Richard S. Payne

Patent number: 7178767Abstract: A multi-leg equipment stand has a unitary user interface. All legs can be adjusted simultaneously, or, an individual leg can be adjusted, by distinct motions of the interface. A collar is near to an equipment support shoulder. Rotation around a vertical axis releases all legs. For a tripod, tilting the collar in one direction releases only one of three legs. The tilt may be toward the leg to be moved. The legs have adjacent, telescoping components. A control rod extends from the collar, through the hollow interior of the upper component, to a jam-plate, at the lower end of the upper component. The plate jams between an inside of the lower component, and an inside of the upper component. The rod passes through the jam-plate. Pushing the rod tilts the jam-plate, freeing it from jamming. A spring returns it to jamming if released. For each leg, the collar underside has a two level cam recess. The rods each have a cam follower surface at their shoulder end.Type: GrantFiled: May 9, 2002Date of Patent: February 20, 2007Assignee: Massachusetts Institute of TechnologyInventors: Jasper L. Steyn, Daniel K. Moon, Brian B. Conaty, Thomas A. Greenwood, Ingrid Shao-Ying Huang, Philip G. Kong, James I. Meyer, Prabhat K. Sinha
