Buoyant matter, and particularly biomass such as seaweed, is sequestered deep in a body of water, fey causing the matter to lose it buoyancy and sink and remain sunk for an extended period. In some examples, the matter is pumped to below a depth at which is loses its natural buoyancy as a result of the ambient water pressure resulting in it naturally sinking to the bottom.

The housing can define a cavity having a first end and a second end. The shuttle can be located within the cavity and define a plurality of indentations. The pinion can be located proximate the shuttle and have a plurality of protrusions sized to mesh with the plurality of indentations during rotation of the pinion. The first and second springs can be mechanically coupled to the housing and the shuttle. Rotation of the pinion in a first direction can translate the shuttle in a first direction towards the first end of the housing and rotation of the pinion in a second direction can translate the shuttle in a second direction towards the second end of the housing.

A method for high resolution projection micro stereolithography for 3-D printing comprising: generating a 3D digital model of the sample to be printed in a computer, slicing the digital model into a sequence of images, wherein each of the images of the sequence represents a layer of the 3D digital model, positioning a transparent printing head relative to a resin vat containing a photo-sensitive resin, moving the transparent printing head into position for selectively exposing the photosensitive resin, sending an image from the sequence of images to a LCD or DLP chip, and together with a light source projecting the image through a lens onto the flat tip of the transparent printing head to initiate cure of the photosensitive resin in areas where the projected image allows light from the light source to reach the photosensitive resin.

An instrument port for introducing instruments into a surgical site, including a port body having a channel running therethrough from a proximal end to a distal end, an instrument sleeve in slidable contact with the channel, creating a gap therebetween, and fluid flow for removing emboli efficiently from the instrument port, wherein the fluid flow includes the gap is provided. A fluid flow system for use in an instrument port is provided. A method of removably securing an instrument sleeve to a port body by anchoring the instrument port to heart tissue, making at least one flood line in a channel, flushing out emboli, and performing surgery with the instrument port.

An apparatus for forming a box or bag that is made of a substrate strip which includes a winder having a mandrel and posts that extend from the mandrel in a direction parallel to a winding and translation axis that rotate together as a unit around the translation axis. The apparatus also has a feeder that includes precursors and a gathering head used for forming the precursors into the strip and feeding the strip to the winder. A motor adjusts the feeder's angle relative to the winder in response to instructions from the controller based on the dimensions of the box or bag. This causes controlled overlap between adjacent windings of the strip on the posts. As the mandrel rotates, the posts draw the strip and wind the strip along a spiral having a length in excess of the depth. Zero waste of precursors is made possible by cutting the substrate perpendicular to its length and folding over the box or bag ends to form an angled seam with respect to the sides of the box.

Electrically conductive columns of intertwined carbon nanotubes embedded in a mass of material flexible, resilient electrically insulating material can be used as electrically conductive contact probes. The columns can extend between opposing sides of the mass of material. Terminals of a wiring substrate can extend into the columns and be electrically connected to an electrical interface to a tester that controls testing of a device under test. A pair of physically interlocked structures can coupling the mass of material to the wiring substrate. The pair can include a receptacle and a protrusion.

A technique facilitates conveyance of equipment along a wellbore or other tubular structure. A tractor is provided with a plurality of wheels oriented to engage a surrounding wall. Rotation of the wheels drives the tractor and causes longitudinal movement of the tractor with respect to the surrounding wall via a tangential force created between each wheel and the surrounding wall. Each wheel comprises teeth having a wheel tooth geometry which enhances cooperation with the surrounding wall. For example, the wheel tooth geometry may be designed to cooperate with the tangential force to push debris out of the teeth of each wheel during rotation of the wheel along the surrounding wall. In some applications, the wheel tooth geometry is designed to present a plurality of raised, rounded surfaces which engage the surrounding wall with a low stress impact.

System and method for conveying

An apparatus provides feedback regarding the material in which tip of the apparatus is located as the tip is advance into matter of varying resistances. The apparatus responds to a change in pressure, force, or other parameter such that when the tip reaches matter of a certain resistance, a change in the parameter is sensed. The apparatus provides a driving force to a penetrating medical device, such as a needle, when the apparatus tip encounters material of high resistance. When the apparatus tip encounters a low resistance material, no further driving force is applied to the apparatus. An inner core may be advanced into the low resistance material for deployment of a gas or a liquid as desired.
