Abstract: A screen intake has a central body with two screens attached on either end. Each of the screens has an interior that communicates with a hollow of the body via flow modifiers. These flow modifiers include one or more pipes disposed in the interior of the screens and through passages in ends of the body. A flow control support device disposed within the body supports the body's sidewall and divides the hollow into at least two portions—each communicating with flow from one of the flow modifiers. The device can include one or more plates disposed adjacent one another within the internal hollow with a peripheral edge attached to an inside of the body's sidewall. At least one of the one or more plates can be solid, or one or more of the plates can define openings therein allowing passage of at least some fluid therethrough.

Abstract: A batch centrifuge having a filter screen that can be expeditiously removed and replaced and that is more rigid and more durable than filter screens that are typically employed in current practice. The batch centrifuge may include a centrifuge basket and a cylindrical filter screen disposed within the centrifuge basket, wherein the filter screen is formed of a plurality of curved panels that fit together at adjoining edges. In some embodiments, each of the curved panels may be small enough to fit through an opening in the top of the centrifuge basket without being bent or otherwise deformed.

Abstract: A smart, movable closure system that allows access to the interior from the exterior of the cabinet, is disclosed. In some embodiments, the movable structure may be coupled with a cabinet interior that is adapted to be kept at a temperature cooler than the exterior cabinet ambient temperature, for example, to store perishable consumer goods in a retail setting. In particular, the smart, movable closure system may include electronic components that display graphical renderings corresponding to one or more products stored in the retail product container. In addition, the smart, movable closure system may include a controller that that determines an inventory status of products in the closure system, and based on the determined inventory status, controls the graphical renderings.

Abstract: An intelligent marketing and advertising platform which provides an innovative merchandising solution for retailers by effectively transforming the glass surface of retail product containers (such as cooler doors) into a non-transparent display of planograms. The merchandising solution provides for digital planograms and pricing management, real time promotional updates and sales data, etc. This is accomplished by converting/transforming the simple glass surface of a retail product container (such as cooler/freezer doors) into digital “smart” screens that provide for innovative advertising solutions. The cooler/freezer doors are configured to use at least one camera to capture images when the doors are opened, in order to effectively take inventory of what is inside the cooler/freezer.

Abstract: Systems and methods are provided herein for rapid detection, separation, purification, and quantification of viral particles in a sample. According to some embodiments, a microfluidic device is provided for receiving the sample which may contain viral particles. An electrode of the microfluidic device may be used to generate dielectrophoretic (DEP) and/or electroosmotic (EO) forces acting on the sample. The applied DEP and/or EO forces may immobilize components of the sample on the surface of the electrode, may aggregate viral particles of the sample in one region of the microfluidic device, and may separate other components of the sample from the viral particles. The techniques may be performed rapidly, for example, in eight hours or less, and may not affect infectivity of the viral particles. In some embodiments, the sample may be labeled to enhance a response of one or more of the sample components to the DEP and/or EO forces.

Abstract: An apparatus for separating an analyte from a test sample, such as bacteria from blood components, based on their dielectric properties, localizing or condensing the analyte, flushing substantially all remaining waste products from the test sample, and detecting low concentrations of the analyte. The module array includes a plurality of microfluidic channels with connecting microfluidic waste channels for directing undesired material away from the analyte. An electric field is applied causing a positive dielectrophoretic force to the analyte to capture the analyte. The electric field is applied to at least one electrode having a plurality of concentric rings or concentric arcs extending radially outwards from a center point, electrically connected to a voltage source such that when voltage is applied to the at least one electrode, the concentric rings or concentric arcs alternate in voltage potential.

Abstract: Methods and apparatus for detection and/or identification of analytes including bacteria using dielectrophoresis and electroosmotic traps. Switching between different frequencies of an applied electric field results in movement of the analyte between dieiectrophoresis and electroosmotic trapping states. The use of edge-based sensing techniques enables the use of electrodes with a larger form factor than nanowire sensors. Signal modulation based on analyte contact with the electrode edge is also described.

Abstract: A vibratory screen assembly includes a rigid frame having a pair of parallel side members that are spaced apart such that a space is provided between them. A tappet assembly extending horizontally across the space between the side members includes a horizontal member having opposing ends secured to the frame. A screen placed over the tappet assembly provides a screening medium having a mesh size. A vibrator motor is located at each of the opposing ends of the horizontal member to form a cooperative pair of vibrator motors that induce vibrations in the horizontal member and in the screen. As the screen vibrates, aggregate material that is smaller than the mesh size passes through the screening medium and aggregate material that is larger than the mesh size does not pass through the screening medium.
