20130329237 | Cell-Based Compression of Digital Images - An m×n pixel cell may be obtained from an input image, each of the pixels having a respective color value. A characterization of the cell may be determined, including determining a lowest color value and a highest color value of the pixels cell. A difference between the highest color value and the lowest color value may be calculated. If the difference is less than or equal to a threshold difference, an output color value inclusively between the highest color value and the lowest color value may be selected, and a first representation of the output color value may be written to an output medium. If the difference is greater than the threshold difference, multiple output color values may be selected, and a second representation of the multiple output color values may be written to the output medium. | 12-12-2013 |

20090101559 | Microconcentrator/Microfilter - The present invention includes a microfluidic filter and concentrator that can separate a filtrate from a fluid containing components, e.g. a suspension of particles, to be removed from the fluid at least to some extent. The filter may employ principals of tangential flow filtration, also known as cross-flow filtration. In one aspect, a microfluidic filter described herein includes at least a first, main channel and one or more secondary, filtering channels that connect to the main channel. Filtration occurs when a fluid portion of a sample that is flowed through the main channel enters one or more of the filtering channels and at least some of the components in the sample do not enter or do not flow through the secondary, filtering channels. The secondary channels may be dimensioned to inhibit flow of components through them, and/or a porous material such as a layer may be positioned to inhibit flow of components through the secondary channels. | 04-23-2009 |
20120121676 | METHOD FOR MANUFACTURING CAPSULES, RESULTING CAPSULES, AND USE OF SAID CAPSULES - The invention relates to a one-step process for manufacturing capsules from 1 to 100 microns with a polydispersity index of less than 10%, to suspensions of capsules obtained via this process, and to the use of these suspensions of capsules. | 05-17-2012 |

20080213593 | Systems And Methods For Forming Fluidic Droplets Encapsulated In Particles Such As Colloidal Particles - The present invention generally relates to systems and methods for forming fluidic droplets comprising particles such as colloidal particles, which may be distributed on the surfaces of the fluidic droplets in some cases, thereby encapsulating the fluidic droplets. The particles at least partially surrounding the fluidic droplet may be colloidal particles in some cases, i.e., forming a “colloidal capsule.” In one set of embodiments, the particles may be positioned on the surface of a fluidic droplet such that the fluidic droplet is able to maintain a shape that, when left undisturbed, is not achievable by an undisturbed fluidic droplet free of discrete particles, for example, elongated or prolate ellipsoid fluidic droplets. Such fluidic droplets may also exhibit unusual properties, for example, plasticity, isolation from electromagnetic fields, certain electrical and/or magnetic properties, and/or mechanical resistance. In certain embodiments, multiple fluidic droplets may be prevented from fusing or coalescing into one droplet when coming into physical contact, due to the presence of particles on the fluidic droplets. However, the fluidic droplets may be induced into fusing or coalescing by initially deforming one or more of the fluidic droplets, e.g., mechanically. | 09-04-2008 |
