Abstract: Apparatus is provided for separating valuable material from unwanted material in a mixture, featuring engineered media made of synthetic material and formed by a body having a polymer surface with a coating functionalized to attract valuable material in a mixture, the polymer surface being made from a polymer having a filler addition added prior to curing in order to enhance coating adhesion and modify polymer surface energy. The filler addition includes hydrophilic or hydrophobic silica added to a pre-cured polymer, including a pre-cured urethane foam; or a hydroxyl, an amine, a carboxyl, a carbonyl or an ester, all having reactive functionality or surface energy properties to enhance the coating adhesion and modify the polymer surface energy. The engineered media is formed by a composite of a polyurethane foam and silica, including either a hydrophilic silica or a hydrophobic silica.

Abstract: A method of manufacturing an elevator of a medical device comprises using an additive manufacturing method, forming a pivot portion at a proximal end of the elevator. The pivot portion tapers proximally such that a proximalmost end of the elevator is thinner than more distal portions of the pivot portion. The method further comprises using the additive manufacturing method, forming a body of the elevator that is distal to the pivot portion. The elevator body includes a surface configured to contact an instrument inserted in a working channel of the medical device.

Abstract: One or more sensor devices are encapsulated on a top surface of a carrier substrate within an elastomer material. The carrier substrate includes one or more recessed channels adjacent to each sensor device which are filled by a portion of the elastomer material to create flanged areas that are level with the top surface of the carrier substrate. A cover which can include a liquid or gas input port or other related structures can be placed over each sensor device and bonded to the carrier substrate at the flanged areas, creating a seal between the cover and the carrier substrate that surrounds each sensor device.

Abstract: A database management engine provides a user interface that allows users to access and modify employee information in a database. The database includes entries for employees, and each database entry includes identifying information about the associated employee. A user can request to modify data within database entries, for instance in order to update information associated with an employee. Responsive to the request, the database management engine identifies liabilities associated with the database modification stemming from associated tax laws. Based on the identified tax liabilities, the engine computes the aggregate tax liability owed by the employer and/or employee. Before modifying a database entry, the engine modifies the user interface to include interface elements detailing the computed aggregate tax liability. The user explicitly can be required to confirm the database modification in view of the aggregate tax liability.

Abstract: Vibration isolation can be provided for a vibration sensitive component to be bonded to electronic circuit boards or other surfaces by an assembly that includes two substrates with rigid portions that are electrically coupled to each other via a flexible interconnect. The rigid portions of the two substrates are bonded together via an elastic structure in a stacked arrangement with the first substrate above the second substrate. The flexible interconnect electrically couples the first substrate to the second substrate and the second substrate is configured to be bonded and electrically coupled to an electronic circuit board or other larger substrate via contacts on a surface of the rigid portion of the second substrate. The vibration sensitive component can be bonded to the rigid portion of the first substrate and couped to the flexible interconnect via the first substrate, thereby coupling it to the second substrate and the larger substrate.

When a first addressing impulse have an electrical polarity is applied to the medium, the first species of particles move in one direction relative to the electric field, but when a second addressing impulse, larger than the first addressing impulse but having the same electrical polarity, is applied to the medium, the first species of particles move in the opposed direction relative to the electric field.

Abstract: Devices, systems, and methods for treating wounds in endoluminal spaces of a patient are disclosed. A device may include an elongate tube defining a proximal end, a distal end, and a lumen, an expandable component adjustably positioned at the distal end of the elongate tube, and a tether coupled to the expandable component and extending proximal from the expandable component through the lumen to a location exterior of the elongate tube. The expandable component may be adjustable between a delivery position within the elongate tube and a fully deployed position at least partially exterior of the elongate tube. The expandable member may be absorbent. A proximal end of the elongate tube may couple to a vacuum source to apply a negative pressure at or proximate the expandable component. An inner member may extend through the elongate tube and be configured to adjustably engage the expandable component.

Abstract: Alignment features formed on a cover substrate allow for a second substrate to be bonded to the cover substrate while ensuring that the second substrate is not titled with respect to a plane defined by the alignment features. Die attachment material is patterned such that it deforms or flows underneath the second substrate while allowing corners of the second substrate to rest on landing areas that are elevated above the top surface of the cover substrate. Some of the landing areas may include additional features that are elevated above the landing areas to form notches which constrain the rotational position of the second in addition to its tilt.

Abstract: An alignment recess formed in a cover substrate such as a cover for a MEMS device allows a second substrate to be bonded to the cover substrate. The alignment recess is larger than the second substrate and has two corner regions diagonally opposite each other where a wall of the recess protrudes to form a notch. The notch is dimensioned such that when the second substrate is disposed within the recess with two opposing corners surrounded by respective notches of the recess, the angular position of the second substrate relative to the cover substrate can be controlled to within a desired amount of rotation.

Abstract: Transaction scheduling is described for a user data cache by assessing update criteria. In one example an event records memory stores a list of events each corresponding to performance of a transaction at a remote resource for a user. The memory has criteria for each event and a criterion value for each criterion and event combination. An event manager assesses criteria for each event by performing an operation on the stored criterion value for each criterion and event combination, assigning a score for each criterion and event combination, and compiling the assigned scores to generate a composite score for each event. The events are ordered based on the respective composite scores and executed in the ordered sequence by performing a corresponding transaction at remote resource. Updated criterion values are stored for executed events.

The lower surface includes a first a set of electrical contacts and a recessed region with a second set of electrical contacts configured to allow a second die to be coupled to the lower surface and electrically coupled to the first die via the second set of contacts. The recessed region is sufficiently recessed to allow the package to be coupled to a mounting surface such as a printed circuit board via the first set of contacts while the second die remains suspended above the mounting surface.

Abstract: A substrate for use in an aqueous slurry has a polymeric coating to provide a compliant and sticky surface. The polymer coating has a chemical to render the surface hydrophobic so as to attract hydrophobic or hydrophobized mineral particles in the slurry. The substrate can take the form of a conveyor belt, a bead, a mesh, an impeller, a filter or a flat surface. The substrate can also be an open-cell foam. The polymeric coating can be modified with tackifiers; plasticizers; crosslinking agents; chain transfer agents; chain extenders; adhesion promoters; aryl or alky copolymers; fluorinated copolymers and/or additives; hydrophobizing agents such as hexamethyldisilazane; inorganic particles such as silica, hydrophobic silica, and/or fumed hydrophobic silica; MQ resin; and/or other additives to control and modify the properties of the polymer.
