Patent number: 9492824Abstract: A method of droplet manipulation utilizing a droplet manipulation device includes activating elements of the device to bring a first droplet into proximity of a second droplet, controlling the elements of the device to alter the shape of at least one of the first and second droplets, and further controlling the elements of the device to move at least one of the first or second droplets until the droplets are in contact about an aggregate area. The elements are controlled in a manner so as to control the area of contact and the degree of mixing of the fluid between the first and second droplets. The method may be employed to move particles of a particulate suspension from the first droplet to the second droplet. The droplet manipulation device may be an electrowetting on dielectric (EWOD) device, which includes shaping electrodes activated to shape droplets, and a bridging electrode activated to join the droplets to transfer fluid between the shaped droplets.Type: GrantFiled: January 16, 2013Date of Patent: November 15, 2016Assignee: Sharp Kabushiki KaishaInventors: Adrian Marc Simon Jacobs, Jason Roderick Hector, Hywel Morgan

Publication number: 20160187758Abstract: An electro-optic display comprising at least two separate layers of electro-optic material, with one of these layers being capable of displaying at least one optical state which cannot be displayed by the other layer. The display is driven by a single set of electrodes between which both layers are sandwiched, the two layers being controllable at least partially independently of one another. Another form of the invention uses three different types of particles within a single electrophoretic layer, with the three types of particles being arranged to shutter independently of one another.Type: ApplicationFiled: March 3, 2016Publication date: June 30, 2016Inventors: Stephen J.

Patent number: 9025152Abstract: An absorption cell for microfluidic chemical analysis made from tinted or colored polymers, for example polymethylmethacrylate (PMMA), in which microfluidic channels are cut. Light is coupled into the absorption cell via two windows (typically 200 um thick) that are retained at either end of the channel. Absorption is measured using a light source, such as a light emitting diode (LED) and a photodiode butted against the windows. Spurious scattered and/or reflected light is absorbed by the colored polymer over the length of the measurement cell, while very little light loss occurs at the coupling windows.Type: GrantFiled: February 4, 2011Date of Patent: May 5, 2015Assignee: University of SouthamptonInventors: Cedric Florian Aymeric Floquet, Hywel Morgan, Vincent Joseph Sieben, Iain Rodney George Ogilvie, Matthew Charles Mowlem
