Abstract: Various embodiments are directed to processing and executing digital asset transfers between two users. An example method includes receiving a data object defining a digital asset transfer, and the data object may be a query from the first user to initiate an outbound transfer to a second user or an approval of a request for digital asset units from the second user. The method further includes retrieving account balance data objects associated with the digital asset accounts for the first and second users. The method further includes, responsive to determining that the digital asset transfer satisfies one or more transfer conditions, executing the digital asset transfer by executing a closed-loop debit from the first user and executing a closed-loop credit to the second user. The method further includes updating the account balance data object to reflect the resulting balances of each digital asset account.

Abstract: Various embodiments of the present disclosure are generally directed to processing conversions of digital assets to fiat currency. An example method includes obtaining a conversion rate for a digital asset via an API, providing the conversion rate via a client device, receiving a digital asset conversion request and executing a digital asset conversion within a configurable time period. Executing the digital asset conversion includes causing digital asset units to be debited from the digital asset user account and causing fiat currency units to be credited to a fiat currency user account. The method further includes dynamically providing a notification of execution of the digital asset conversion via the client device, updating account balance data objects associated with the digital asset user account and the fiat currency user account, and subsequent to executing the digital asset conversion, executing a fiat currency transaction (e.g., a settlement) with a digital asset exchange system.

Abstract: An atherectomy catheter having an inner drive shaft which rotates a distal rotary tissue borer with a helical cutting surface which enables the catheter to cut through and cross a CTO. Additionally, the atherectomy catheter has a distal cutting element rotated by an outer drive shaft configured to cut material from the wall of a vessel at a treatment site as the catheter is pushed distally through the treatment site. The atherectomy catheter includes a collection chamber positioned proximally of the cutting element and rotary tissue borer. The atherectomy catheter may include means to direct material cut from the treatment site into the collection chamber, means to break down larger portions of material that may block or clog the collection chamber and means of transporting the material collected from the treatment site to a proximal opening in the atherectomy catheter.

Abstract: A deployment mechanism of a tissue-removing catheter includes a socket member received in a catheter body that is capable of moving longitudinally therein, and a ball member extending distally from the distal end portion of the cutting element and operatively connected to the socket member. The ball member is constrained axially relative to the socket member and is capable of pivoting relative to the socket member for allowing pivoting of the cutting element relative to the socket when the cutting element is moved from a retracted position to a cutting position.

Abstract: Retrievable blood clot filter devices implantable within a blood vessel, including methods and apparatuses for retrieving such devices, are disclosed. The retrievable blood clot filter device can include an apical head, and a plurality of elongated filter legs configured to expand between a collapsed position and an expanded position within the blood vessel. A bendable anchoring member disposed on one or more filter support members can be used to secure the blood clot filter device along the inner wall of the blood vessel. The anchoring members can be configured to bend and retract into a number of filter tubes slidably disposed along the support members, allowing the blood clot filter device to be removed with a retrieval apparatus.

Abstract: A lead response system is provided comprising a customizable lead delivery rules engine and a customizable escalation rules engine for delivering leads to appropriate responders and re-routing undeveloped leads to different responders. Each delivery rule includes two or more criteria which may be met in order for the lead to be delivered to the responder specified in the particular rule. A lead that is not accepted by the responder to whom it was delivered within a user-defined time frame is re-routed for delivery to a new responder according to a set of escalation rules. The escalation rules may include delivery instructions specifying the new responder or may re-route the lead to the delivery rules engine for delivery to a new responder according to a re-application of the delivery rules.

The aerial dispersal unit also provides a glue substance, a pump, and a motor to drive the pump for transporting the glue substance from a storage container to the dispensing chamber for mixing with the insect control substance. The dispensing chamber is provided with a motor for forcing the insect control substance mixed with the glue substance out an exit portal for disbursement over the designated area.

Abstract: Substrate preparation systems comprising multi-zone cascade brush scrubbers having sonic assemblies disposed between one or more of the scrubber zones for cleaning of disk-shaped substrates, including silicon wafers and disks for data storage devices, such as hard disk drives (HDD), compact discs (CD) and digital video discs (DVD). The system method combines a sonic particle dislodgement/removal assembly into a cascade brush scrubber line comprising a longi-tudinal array of brush pairs in which the substrates process through preparation zones defined by each pair of brushes, the substrates being transited longitudinally through the zones while rotating on an axis normal to their faces. Piezoelectric transducer arrays transmit sound energy to one or both face(s) of the substrate to dislodge and/or remove particles, and the scrubber simultaneously or thereafter sweeps away the particulates.

Abstract: In accordance with the present invention, a lower body support device is shown herein. The lower leg of the user is positioned such that the knee of the user rests within the area defined by a knee frame, the shin of the user rests within the area defined by a bend frame, and the ankle of the use rests in the region of an ankle frame. A strap bar means connected to the knee frame allows for the securing of a knee pad, such knee pad is user chosen, worn by the user and strapped to the knee frame via the strap bar means. A seat insert is secured to the top of the ankle frame. The user wears one leg support device on each leg. While resting on a surface, the bottom of the knee frame and the bottom of the ankle frame, and possibly the knee pad worn by the user, contact said surface. Preferably, the buttocks of the user rests on the seat insert, which transfers a significant portion of the weight of the user to the surface via the frames.
