Abstract: An example device may include processing circuitry and a management controller. The processing circuitry may include a communications interface that includes a first register and a second register. The first register may include a freshness bit and a number of first data bits. The second register may include a number of second data bits that correspond, respectively, to the first data bits. The processing circuitry may write variously to the first data bits in response to detected events, set the freshness bit in response to the management controller reading the first data bits, and reset the freshness bit if any of the first data bits are written to. The management controller may read the first data bits, perform predetermined processing based thereon, write to the second data bits based on the predetermined processing, and request a register transfer.

Abstract: A printer fabricates an object from a build material based on a computerized model and a fused filament fabrication process. A nozzle for depositing the build material has an interior diameter approaching an outer diameter of build material fed to the nozzle in order to reduce extrusion and resistance forces imposed by the nozzle during deposition, while adequately constraining a planar position of the build material for accurate material deposition in a computer-controlled fabrication process.

Abstract: A printer fabricates an object from a computerized model using a fused filament fabrication process and a metallic build material. The Seebeck effect can be employed to monitor a temperature difference between a build material and a nozzle that is extruding the build material based on voltage. The temperature difference can, in turn, be used to control operation of the printer or to determine an absolute temperature based on direct measurement of a temperature of the nozzle.

Abstract: A printer fabricates an object from a computerized model using a fused filament fabrication process and a build material. One or more energy directors such as ridges are formed in an exposed surface of the deposited build material to provide regions of high, localized contact force that can improve interlayer bonding between successive layers of the build material. An ultrasonic vibrator can also usefully be incorporated into the printer to apply additional energy along these energy directors during deposition of a subsequent layer.

A plasma depassivation wash is applied during deposition to remove oxidation and improve interlayer bonding between successive layers of the metallic build material. Other techniques such as ultrasonic vibration, formation of energy directors, joule heating, and the like, may be used in combination to form a mechanically robust bond between layers.

Abstract: A stowable, collapsible floating waterproof fishing net that may be employed at the surface of a body of water to retain marine life, or any article in the water, adjacent and outside of a water craft, vessel or person. It has a flexible, upper floatable ring that forms a concave well below the surface with the attached fabric. The ring twistably contorts or coils and stacks upon itself going from a hoop to a stacked coil configuration, so as to reduce the volume of the net when collapsed, approximately 50 fold from its enclosable, opened volume and its surface area by more than 12 fold. It generally utilizes an opaque fabric flange extending from the floatable ring into the concave well to obstruct the entrapped marine life's vision and the diffracted surface light so as to drive the marine life to the bottom of the well, therein reducing their opportunity to escape by leaping over the ring.
