Abstract: A liquid dispensing module includes a dispenser body assembly, a flexible seal, a needle, and an actuator. The dispenser body assembly includes a liquid inlet, a discharge outlet, and a flow channel including a valve seat between the inlet and outlet. The flexible seal engages the dispenser body assembly and includes a downstream end. The needle includes an enlarged portion engaging and retaining the downstream end of the flexible seal to place the flexible seal in lengthwise compression between the enlarged portion and the dispenser body assembly. The needle also includes a valve element that moves between open and closed positions. The flexible seal prevents liquid from leaking out of the flow channel.

Abstract: A transseptal cannula assembly for directing blood from the heart of a patient and a minimally invasive method of implanting the same. The transseptal cannula assembly includes a flexible cannula body having proximal and distal portions with a lumen therebetween, a tip coupled to the distal portion of the flexible cannula body, and first and second anchors coupled to the tip. The anchors can be configured to be deployed from a contracted state to an expanded state and are configured to engage opposite sides of the heart tissue when in the expanded state. The anchors resist movement of the cannula assembly along a lengthwise central axis of the flexible cannula body.

Abstract: Methods for operating a material dispensing system. The method includes measuring numerical values of an operating parameter, such as line velocity, material pressure, or material temperature, of the dispensing system to predict a future numerical value of the operating parameter. The predicted numerical value of the operating parameter is used to accurately define a start time, which is measured from the detection of the presence of a workpiece being transported past an applicator of the dispensing system, at which to initiate dispensing of the material from the applicator. A calibration procedure is provided for deriving a mathematical relationship used to determine the predicted numerical value of the operating parameter.

The rotor includes first and second straps that respectively wrap around two diametrically-opposed ones of the bucket supports for restricting outward movement of the two bucket supports relative to the rotor core. The first and second straps intersect one another at a location through the axis of rotation of the rotor.

Abstract: A bedding foundation having a nestably stackable spring assembly, including a border wire having a generally rectangular cross-section. The foundation's spring assembly may be nestably stacked with numerous other such assemblies for transportation, thereby avoiding the need to compress and tie the assembly for shipping. Each foundation assembly includes a number of corrugated support wires having alternating peaks and valleys. The border wire is generally rectangular in cross-section to reduce wire costs without compromising beam strength of the border wire.

Abstract: The invention relates to an improved aircraft electronics cooling system for an aircraft having a liquid cooling system (2), the aircraft electronics cooling system providing a thermal coupling between an electronic device (40a, 40b, 40c, 40d, 42, 44) to be cooled and the liquid cooling system (2) of the aircraft. A coolant delivered by the liquid cooling system (2) may flow through a board of the electronic device (40a, 40b, 40c, 40d), through a heat sink on which the electronic device (42) is arranged and/or through a housing in which the electronic device (44) is arranged. The coolant may be permanently in the liquid state in a cooling circuit. The coolant may vaporize at least partially while cooling the electronic device.

Abstract: The invention relates to a method and device for the cross-referencing of identification (1) of tissue slice supports (2), for microtomised analytical samples still to be mounted thereon, with identification information (3) of a tissue sample holder (4) of a tissue sample (5) which is not yet microtomised. The conventional problem of cross-referencing is improved in a simple manner, whereby the identification information (3) for the tissue sample holder (4) is automatically detected when positioned in the microtome (6) and an identification (1) corresponding thereto is automatically transferred to at least one tissue slice support (2) and that tissue slice support (2), provided with the identification (1), is dispensed for application of the tissue sample slice at the moment when a tissue sample slice must be applied to a tissue slice support (2).

Abstract: A multithreaded rendering software pipeline architecture utilizes a rolling context data structure to store multiple contexts that are associated with different image elements that are being processed in the software pipeline. Each context stores state data for a particular image element, and the association of each image element with a context is maintained as the image element is passed from stage to stage of the software pipeline, thus ensuring that the state used by the different stages of the software pipeline when processing the image element remains coherent irrespective of state changes made for other image elements being processed by the software pipeline. Multiple image elements may therefore be processed concurrently by the software pipeline, and often without regard for synchronization or serialization of state changes that affect only certain image elements.

Abstract: A system for ventilating an aircraft cabin includes an air supply pipe connected to an air source, and a plurality of air distribution lines branching off from the air supply pipe. In a first operating state, the ventilating system is adapted to blow out the air, flowing through the air supply pipe, directly from the air distribution lines into the aircraft cabin. In contrast, in a second operating state of the ventilating system, at least some of the air distribution lines are connected to connecting lines which supply the air, flowing through the air supply pipe, to air outlets arranged in a distributed manner in the aircraft cabin.

Abstract: A circuit arrangement and method utilize a universal, standardized inter-layer interconnect in a multi-layer semiconductor stack to facilitate interconnection and communication between functional units disposed on a stack of semiconductor dies. Each circuit layer in the multi-layer semiconductor stack is required to include an inter-layer interface region that is disposed at substantially the same topographic location such that when the semiconductor dies upon which such circuit layers are disposed are arranged together in a stack, electrical conductors disposed within each semiconductor die are aligned with one another to provide an inter-layer bus that is oriented vertically, or transversely, with respect to the individual circuit layers.

The apparatus includes at least one concavity positioned and dimensioned to receive the feature such that the feature is shielded from the plasma. The apparatus further includes a window through which the plasma removes the extraneous material. The method generally includes removing the extraneous material while shielding the feature against plasma exposure.
