20140328999 | Dynamic and Switchable Slippery Surfaces - The present disclosure describes a strategy to create self-healing, slippery liquid-infused porous surfaces (SLIPS) that can be modified as desired. Roughened (e.g., porous) surfaces can be utilized to lock in place a lubricating fluid, referred to herein as Liquid B to repel a wide range of objects, referred to herein as Object A (Solid A or Liquid A). Use of an external stimuli or degradation of the Liquid B can be utilized to change the characteristics of SLIPS structures reversibly or irreversibly that may be desired in a number of different applications. Numerous characteristics, such as adhesion, optical, mechanical, and the like, can be dynamically changed. | 11-06-2014 |
20150152270 | SLIPPERY SELF-LUBRICATING POLYMER SURFACES - The present disclosure describes a strategy to create self-healing, slippery self-lubricating polymers. Lubricating liquids with affinities to polymers can be utilized to get absorbed within the polymer and form a lubricant layer (of the lubricating liquid) on the polymer. The lubricant layer can repel a wide range of materials, including simple and complex fluids (water, hydrocarbons, crude oil and bodily fluids), restore liquid-repellency after physical damage, and resist ice, microorganisms and insects adhesion. Some exemplary applications where self-lubricating polymers will be useful include energy-efficient, friction-reduction fluid handling and transportation, medical devices, anti-icing, optical sensing, and as self-cleaning, and anti-fouling materials operating in extreme environments. | 06-04-2015 |
20150209198 | Selective Wetting and Transport Surfaces - Methods and compositions disclosed herein relate to liquid repellant surfaces having selective wetting and transport properties. | 07-30-2015 |
20150210951 | MULTIFUNCTIONAL REPELLENT MATERIALS - Methods and compositions disclosed herein relate to liquid repellant surfaces having selective wetting and transport properties. An article having a repellant surface includes a substrate comprising fabric material and a lubricant wetting and adhering to the fabric material to form a stabilized liquid overlayer, wherein the stabilized liquid overlayer covers the fabric material at a thickness sufficient to form a liquid upper surface above the fabric material, wherein the fabric material is chemically functionalized to enhance chemical affinity with the lubricant such that the lubricant is substantially immobilized on the fabric material to form a repellant surface. | 07-30-2015 |
20150285454 | Dynamic Light Control System And Methods For Producing The Same - The present application describes dynamic light control system that, can dynamically adapt to different sun positions and interior lighting levels. The dynamic light control system, includes two or more confinement panes and one or more light redirecting elements positioned therebetween. The light redirecting elements are arranged to deform the light redirecting elements in response to a change in the position of the sun. In addition, one or more fluidic-channels are formed between the light redirecting elements and the confinement panels, that can be filled with any desired fluid to provide additional dynamic changes depending on the desired characteristics. | 10-08-2015 |

20160110575 | Dimensioning and Barcode Reading System - A system and method for calibrating a barcode scanning tunnel comprises providing a scanning tunnel having a moveable surface, a camera, and a dimensioning device. Orientations of the dimensioning device and camera are estimated. Instances of a calibration object on the moveable surface are acquired by the dimensioning device and the camera, and a relationship is defined between the two devices. A calibration object is moved along the moveable surface through the devices' fields of view, controlling the camera's focal distance according to the relationship, so that the dimensioning device and the camera acquire instances of the calibration object, and the relationship is revised. | 04-21-2016 |
