Abstract: Strip cladding heads having strip pressure limits and strip cladding systems with strip cladding heads having strip pressure limits are disclosed are disclosed. A disclosed example cladding head for a strip cladding system includes a first contact jaw comprising first and second contacts to deliver welding power to a cladding strip that is driven between the first and second contacts, a first contact pressure adjuster to set a first pressure applied by the first and second contacts to the cladding strip, and a first strip lock preventer to limit the first pressure applied by the first and second contacts to the cladding strip to less than a threshold pressure.

Abstract: Strip cladding heads having independent strip pressure adjustments and strip cladding systems with strip cladding heads having independent strip pressure adjustments are disclosed. A disclosed example cladding head for strip cladding system includes a first contact jaw, a second contact jaw, and a third contact jaw. The first contact jaw includes first and second contacts to deliver welding power to a cladding strip that is driven between the first and second contacts. The second contact jaw includes third and fourth contacts to deliver the welding power to the cladding strip that is driven between the third and fourth contacts.

Abstract: Cladding strip feeders having independent pressure rollers and strip cladding systems with cladding strip feeders having independent pressure rollers are disclosed.

Abstract: Granular welding flux delivery devices and strip cladding systems with granular welding flux delivery devices are disclosed. A disclosed example granular welding flux delivery device includes a hopper having: an intake opening to receive granular welding flux; a chute; and an output opening to output the granular welding flux to an electroslag strip cladding process, a submerged arc welding process, or a submerged arc strip cladding process. The example granular welding flux delivery device further includes a chute divider positioned within the chute to reduce an intake rate of granular material through the intake opening by reducing a cross-section of the chute based on a dimension of the chute divider. The disclosed example granular welding flux delivery device includes an adjustable output cover attached to the chute proximate to the output opening to extend or retract a length of the chute by adjusting a location of the output opening along the chute.

Abstract: An antenna-diversity receiver receives data units from a transmitter in a frequency-hopping communication system. The frequency-hopping system has a channel set comprising of multiple channels, each having its own frequency range. The channel set comprises a set of multiple advertising channels and a set of multiple data channels. The receiver comprises an antenna set of multiple antennas. The transmitter has an advertising mode in which the transmitter transmits an advertising signal and switches from one advertising channel to another advertising channel in accordance with a sequence of advertising intervals, each advertising interval comprising an advertising packet. The receiver has an antenna sampling mode in which the receiver receives, successively for each combination of antenna and advertising channel, advertising packets.

Abstract: In one aspect, the invention provides a device comprising a catheter. In another aspect, the invention provides a method of removing an agent from blood.

Abstract: The disclosed technology describes compositions and methods useful for providing cell based therapy. For example, one embodiment of cell based therapy involves the regeneration of injured tissue and/or promoting wound healing. Certain embodiments provide improved therapeutic compositions using microbubbles by delivering biological progenitor cells to the injured tissues. The administration of the microbubbles is directed by acoustic radiation forces that interact with embodiments of microbubbles comprising an acoustically active gas. As such, a high efficiency of progenitor cell delivery to injured tissue is realized. One advantage of this technique over targeted delivery of pharmaceutical compounds, is that the delivered progenitors cells may be derived from the patient (i.e., personalized therapy), thereby avoiding side effects, allergic reactions, and overall problems associated with refractive drug responses.

Abstract: The invention provides a system and a method for removal of contrast from blood. In one aspect, the invention provides a catheter for removal of contrast from the veins that drain the cerebral circulation. In a second aspect, the invention provides a method for removing contrast from blood by contacting the blood with a sorbent.
