Abstract: A fabrication device includes a build surface to receive layers of material for production of a 3-dimensional solid representation of a digital model and an imaging component to bind respective portions of the build material into cross sections representative of portions of data contained in the digital model. The device can include a system to recirculate and/or homogenize material prior to use in the fabrication process. The device can include a system for controlling the density of the printed part. An exemplary object made by the fabrication device can include a powder composite component using any of a variety of powder materials. The exemplary object can be further post-processed to produce a high precision metal or ceramic component. The fabrication device can include a selective deposition unit for selectively depositing a supplemental build material at high resolution. The fabrication device can include an imaging unit with extended usage life.

Abstract: In some embodiments, a negative pressure wound therapy device includes a negative pressure source and a controller configured to, in response to determining that the negative pressure source is directly fluidically connected to a wound dressing without a canister between the two, operate the negative pressure source in a first mode; otherwise, operate the negative pressure source in a second, different mode. The controller can be further configured to, in response to determining that a level of activity of the negative pressure source over a first time duration satisfies at least one of a leak or blockage condition, provide an indication of at least one of a leak or blockage and, in response to determining that the level of activity does not satisfy the at least one of the leak or blockage condition over a second time duration subsequent to the first time duration, discontinue providing the indication.

Abstract: Embodiments of negative pressure wound therapy systems and methods for operating the systems are disclosed. In some embodiments, a system includes a negative pressure source, a wound dressing configured to be positioned over a wound, and optionally a canister configured to store fluid aspirated from the wound. The negative pressure source, wound dressing, and canister (when present) can be fluidically connected to facilitate delivery of negative pressure to the wound. The system can be configured to automatically detect whether the canister is positioned in the fluid flow path between the negative pressure source and the dressing while negative pressure source provides negative pressure to the wound dressing. Operation of the system can be adjusted based on whether presence of the canister has been detected. For example, a value of an operational parameter can be set to indicate that the canister is present.
