Abstract: A container has a sheet of one or more first flexible materials; a seam around a circumference of the sheet; a cinch tie enclosed within the seam and exposed at each of at least two notches in the seam on opposite sides of the sheet; and a barrier flap of a second flexible material secured to a first side of the sheet along a line that includes the center of the sheet, wherein the barrier flap is configured to divide an interior space of the container into a first compartment and a second compartment when the container is closed, and wherein the barrier flap is configured to be further secured at a location on the first side of the sheet proximal to the circumference; wherein the cinch tie is configured to close the container by drawing the seam shut when pulled out through the at least two notches.

Abstract: Methods are provided for of driving a bistable electro-optic display having at least first and second pixels separated by an inter-pixel gap. In one method, there is applied to the first pixel a drive pulse which drives the pixel to one extreme optical state, and there is applied to the second pixel, which is in this extreme optical state, a reinforcing pulse of the same polarity as the drive pulse. In a second method, a drive pulse applied to the first pixel drives that pixel away from one extreme optical state, and an inverse reinforcing pulse applied to the second pixel is of opposite polarity to the drive pulse. The drive methods reduce edge ghosting or blooming.

Abstract: A first electrophoretic medium comprises an electrically charged particle suspended in a suspending fluid, the particle having a polymeric shell having repeating units derived from at least one monomer the homopolymer of which is incompatible with the suspending fluid. A second, similar electrophoretic medium comprises a suspending fluid, and first and second types of electrically charged particle suspended in the suspending fluid, the two types of particle having differing optical characteristics but both having polymeric shells. The polymeric shells are arranged such that homoaggregation of the two types of particles is thermodynamically favored over heteroaggregation.

Abstract: An electrophoretic medium comprises discrete droplets of an electrophoretic internal phase comprising a fluid and carbon black particles in the fluid. The droplets are surrounded by a polyurethane binder formed by a diisocyanate and a polyether diol, at least 20 mole per cent of the diisocyanate being an aromatic diisocyanate.
