Patent number: 10551610Abstract: Gravitational Janus microparticle having, a center-of-mass, a center-of-volume, and a non¬uniform density, wherein: the center-of-mass and the center-of-volume are distinct. When suspended in a fluid, the microparticle substantially aligns with either: i) the gravitational field; or ii) the direction of an acceleration, such that the Janus microparticle is in substantial rotation equilibrium. After perturbation from substantial rotational equilibrium, the Janus microparticle reversibly rotates to return to substantial rotational equilibrium. The gravitational Janus microparticle may comprise at least two portions, each having distinct physical and/or chemical characteristics, wherein at least one portion provides a detectable effect following rotation and alignment of the microparticle.Type: GrantFiled: December 23, 2015Date of Patent: February 4, 2020Assignees: National Research Council of Canada, Bank of CanadaInventors: Daniel Brassard, Lidija Malic, Keith J.

Patent number: 6697554Abstract: An adaptive optical waveguide router in which routing paths may be dynamically created by the use of a scanning system. The optical router interconnects at least one optical input to a at least optical output. The optical waveguide layer employed is substantially comprised of a photosensitive material which has a change in index of refraction at one optical wavelength when exposed to a different optical wavelength and which, in some way, may be restored to it's original state. One such material is Bacteriorhodopsin which shows a photocycle in the visible region of the optical spectrum. The scanning system, in response to routing information, traces a routing path(s) between an input(s) and a selected output(s) which alters the index of refraction in the path(s) traced in the photorefractive material. An optical input signal then propagates along the traced path between the selected input(s) and the selected output(s).Type: GrantFiled: May 20, 2002Date of Patent: February 24, 2004Assignee: Nortel Networks LimitedInventors: Steven P.
