Publication number: 20140355101Abstract: A pixel device using optically active fluid contained within elastomeric materials and actuated through dielectric elastomer membrane is disclosed. The underlying mechanism of optical contrast in this display pixel is the spread and contraction of the fluid contained within a pre-stretched elastomer membrane and a substrate. The actuation mechanism for the fluid flow is a dielectric elastomer membrane coated with compliant electrodes on both sides. When both electrodes are connected to a voltage source, the oppositely charged electrodes attract each other, compressing the sandwiched elastomer membrane in the thickness direction but increasing its lateral dimension. Due to geometrical constraint, the change in the membrane lateral dimension results in the net volume change of the fluid reservoir, causing optically active fluid to move from the display cavity into the fluid reservoir or vice versa.Type: ApplicationFiled: January 23, 2013Publication date: December 4, 2014Applicant: President and Fellows of Harvard CollegeInventors: Samuel Shian, David Clarke, Roger Diebold

Patent number: 8471245Abstract: An implementation of a single qubit phase gate for use in a quantum information processing scheme based on the ?=5/2 fractional quantum Hall (FQH) state is disclosed. Using sack geometry, a qubit consisting of two ?-quasiparticles, which may be isolated on respective antidots, may be separated by a constriction from the bulk of a two-dimensional electron gas in the ?=5/2 FQH state. An edge quasiparticle may induce a phase gate on the qubit. The number of quasiparticles that are allowed to traverse the edge path defines which gate is induced. For example, if a certain number of quasiparticles are allowed to traverse the path, then a ?/8 gate may be effected.Type: GrantFiled: November 8, 2011Date of Patent: June 25, 2013Assignee: Microsoft CorporationInventors: Parsa Bonderson, Kirill Shtengel, David Clarke, Chetan Nayak

Publication number: 20120133025Abstract: An apparatus includes an electrostatic discharge (ESD) protection device configured to protect a circuit from ESD conditions. The protection device includes an emitter region having a first diffusion polarity; a collector region laterally spaced apart from the emitter region, and having the first diffusion polarity; and a barrier region interposed laterally between the emitter region and the collector region while contacting the emitter region. The barrier region has a second diffusion polarity opposite from the first diffusion polarity. The device can further include a base region having the second diffusion polarity, and laterally surrounding and underlying the emitter region and the barrier region. The barrier region can have a higher dopant concentration than the base region, and block a lateral current flow between the collector and emitter regions, thus forming a vertical ESD device having enhanced ESD performance.Type: ApplicationFiled: November 29, 2010Publication date: May 31, 2012Applicant: ANALOG DEVICES, INC.Inventors: David Clarke, Paul Daly, Patrick McGuinness, Bernard Stenson, Anne Deignan
