Abstract: Magnetic latching valves for a vehicle engine have a housing having a first port and a second port in controlled fluid communication with one another. The housing encloses a linearly translatable armature seated within a solenoid and connected to a primary poppet valve. The armature is movable between an open position and a closed position, respectively, after a pulse of voltage to the solenoid and is in an unpowered state thereafter. A permanent magnet is fixedly seated in a position to magnetically latch the armature in a fully open position. A spring is seated to bias the primary poppet valve closed when the armature is in the closed position. The spring has a spring rate that mechanically relieves pressure by opening the primary poppet valve a distance less than the fully open position when the spring force is exceeded, thereby also allowing flow in the primary flow direction.

Abstract: A system for verifying the authenticity of physical goods uses an NFC tag embedded in the product. An NFC reader positioned within range of the tag reads a unique identification number from the tag. The unique identification number may be used to generate an authentication code. During production, the manufacturer generates a blockchain record as a function of the authentication code. The blockchain record includes at least one additional identifier corresponding to the manufacturer. A consumer uses a mobile device to read the NFC tag and obtains the authentication code as a function of the unique identification number. Having the authentication code, the mobile device accesses the record in the blockchain and obtains the identifier corresponding to the manufacturer. Based upon scanning the NFC tag, the consumer is thereby able to obtain an identifier of the manufacturer to ensure authenticity of the product being purchased.

Abstract: A breach detection system for an internal combustion engine having a crankcase, an intake manifold, a positive crankcase ventilation valve, a crankcase ventilation tube with a flow control system therein, and a pressure sensor between the flow control system and the crankcase. The flow control system subdivides the crankcase ventilation tube into a plurality of parallel conduits—a first conduit having a normally closed check valve that opens under a first preselected pressure drop in a first direction from the air intake to the crankcase, and a second conduit having either a second check valve that opens under a second preselected pressure drop in a second direction opposite the first direction or a restriction profile having a third preselected pressure drop that is the same in both the first and second direction. When the pressure sensor detects no pressure drop there is a breach in the system.

Abstract: Check valve inserts define a valve seat for an open position of a check valve and have an outer support seatable in an internal chamber of the check valve and have an inner annular ring spaced radially inward from the outer support by a rib that angles axially toward a central longitudinal axis to position an upper surface of the inner annular ring a distance axially beyond an upper surface of the outer support. Check valves have a housing defining an inlet port, an outlet port, and a chamber in fluid communication with the inlet and outlet ports, have the check valve insert seated with the chamber, and have a seal disc moveable within the chamber between the open position defined by the inner annular ring of the check valve insert and a closed position. The seal disc is translatable in response to a pressure difference across the seal disc.

Abstract: Described herein are systems, devices, and methods for treating a thrombosis. In some embodiments, an apparatus may include a sleeve defining a first lumen, and an aspiration catheter defining a second lumen, the aspiration catheter slidably disposed within the first lumen. The aspiration catheter may include a proximal end coupleable to a vacuum source configured to apply a vacuum pressure within the second lumen to draw a thrombus into the second lumen, and an expandable tip configured to transition between a retracted configuration in which the expandable tip is constrained within the sleeve and an expanded configuration in which at least a portion of the expandable tip is disposed distal to the sleeve. The expandable tip in the expanded configuration can have a funnel-shaped profile that gradually increases in diameter from a proximal end of the expandable tip to a distal end of the expandable tip.

Abstract: A flipgrip system for a phone. The flipgrip includes two hinging legs that unfold into an X shape, and fold flat. A ring adheres to the rear of the phone and a base can snap onto the ring. The base can spin relative to the ring and also be removed from the back of the phone. The first and second legs hinge relative to the base, out into the X shaped position, or in to the folded flat position.

Abstract: Check valves have a housing defining an internal cavity and a first port and a second port both in fluid communication with the internal cavity and have a hemispherical poppet sealing member within the internal cavity and translatable between a closed position against an annular seat within the internal cavity of the housing and an open position. The annular seat, in a longitudinal cross-section through the check valve, defines a convex spherical radius and, in the closed position, a convex surface of the hemispherical poppet sealing member is sealing engaged with the convex spherical radius of the annular seat.

Abstract: Flow control devices herein have a housing defining a plurality of parallel conduits. The first conduit has a normally closed check valve defined to open under a first preselected pressure differential controlling flow through the first conduit in a first direction of flow. The second conduit has a normally neutral check valve defined to open under a second preselected pressure differential in a second direction of flow that is opposite the first direction of flow. The third conduit defines a restriction profile, i.e., has a restrictor, having a third preselected pressure differential. The flow control devices are included as part of an engine system, more specifically a crankcase ventilation breach detection system.
