Abstract: Provided is a system for correcting the audio received by an audio sensor that has been distorted by the presence of water in a port associated with the audio sensor. More specifically. wearable computing devices can include audio sensors that can detect audio signals in the vicinity of the wearable computing devices. To enable the audio sensors to capture audio signal data more accurately, the wearable computing device can include a port (e.g., a microphone or “mic” port) that connects the audio sensor to the exterior of the wearable computing device. However, in some circumstances, the port can become partially or totally filled with water. For example, when a user is swimming while wearing the wearable computing device, the wearable computing device may be submerged and the port can become filled with water.

Abstract: Systems/techniques that facilitate de-identified search of part designs are provided. In various embodiments, a system can access a part design file provided by a client device, wherein the part design file can comprise a computer-aided design (CAD) geometry of a part. In various aspects, the system can search an historical database for a same or similar instance of the part, via performance of a multi-staged search. In various instances, the multi-staged search can be based on a cryptographic hash of the part design file, on a spatial hash of the CAD geometry, and on an anonymized feature vector extracted from the CAD geometry. In various cases, the system can return, to the client device and in response to the multi-staged search, an electronic notification indicating whether the same or similar instance of the part was identified.

Abstract: A flow passage (70) is shown in the form of two successively linked, substantially parallel, adjacent, open top channels (12A, 14A) to form part of an algae cultivation system. The forward flow of the water passes in sequence through the respective open top channels (12A) and (14A) of flow passage (70), in the direction of arrow ‘A’ and then is then recirculated back into to the channel (12A), and so on. The combination of added nutrients, sunlight and agitation of the fluid flow encourages the growth cultivation of the biological organisms which are continually suspended in the flowing water. Such a flow passage (70) can be used as a standalone passage used as part of a system for cultivation of biological organisms, or it can also form one basic unit of a modular system which is arranged in use to have several such flow passages linked together in use. Such a reconfigurable apparatus gives the user the flexibility to cultivate different algae products both separately and simultaneously.

Abstract: In an emergency run down unit for a superconductive magnet assembly, a quench in the magnet is induced by the release of stored mechanical energy or by direct manual actuation.

Abstract: The invention is a method of dehydrogenating a hydrocarbon, especially an alkane, to form an unsaturated compound, especially an alkene, by contacting the alkane with a catalyst comprising a form of carbon which is catalytically active for the dehydrogenation reaction. The catalyst may be formed by passing a hydrocarbon over a metal compound at a temperature greater than 650° C.

Abstract: A device for centering a work piece with respect to a centerline of a tool includes a radially-stationary component rigidly secured with respect to the tool such that the radially-stationary component and the tool are concentric. A biasing mechanism is biased away from the radially-stationary component to apply substantially equally-distributed radial force at a periphery of the work piece to thereby center the work piece with respect to the tool. A method of broaching a work piece having an inner and an outer diameter includes machining the outer diameter and then applying circumferentially-distributed radial force to the inner diameter or the outer diameter to thereby center the work piece with respect to a broach tool. After the applying step, the method includes broaching the inner diameter of the work piece using the broach tool.

Abstract: The invention provides a material for use in a wound dressing or wound implant, the material comprising a plurality of beads, wherein each bead comprises a porous core of a first bioabsorbable material and a substantially non-porous layer of a second bioabsorbable material around the core. The porous core is preferably a sponge formed by freeze-drying a liquid suspension of the first bioabsorbable material. The preferred diameter of the beads is 0.1-4.0 mm, and the beads are preferably dispersed in a liquid or solid matrix. The invention also provides a method of making beads for use in the materials of the invention.

The bag filling machine is capable of bottom filling and sealing both paper and plastic bags having gusseted or flat sides with little or no modification.

Abstract: Absorbable implant materials having controlled porosity are formed by a method comprising the steps of: providing a dispersion of a bioabsorbable polymer, such as collagen, in a first solvent, such as water; adding particles of a second material, e.g. frozen water droplets or ice particles to the dispersion; followed by freezing the dispersion to form a frozen dispersion having the particles embedded therein, and removing both the first solvent and the second material from the frozen dispersion by freeze-drying or solvent extraction to leave the porous implant material. The invention also encompasses the use of such implant materials for wound healing applications.

Abstract: An apparatus for shouldering and deaerating filled bags provides rapid expulsion of excess gas from flexible top-closure bags containing particulate material. The automated apparatus permits completely controlled handling of the filled bags from the filling station through their movement to a bag closing station. The filled bag is transported to the shouldering and deaerating station where a portion of its top edge is clamped and held by upwardly-biased bag grippers while the contents are settled, compacted and degasified by vibration. Pressure rollers mounted on the front and rear of the bag below the bag grippers compressively roll downward to collapse the bag top and expel gas upwardly therefrom. Downward movement of the rollers ceases when indirect contact with the bag contents activates a limit switch or servo mechanism.

The rear face of the post is formed with a horizontally extending notch having upper and lower surfaces. When an impact load is transmitted to the front face of the post, the post is caused to distort in a region including the notch so that the upper and lower surfaces of the notch close towards one another prior to any fracture at or adjacent the front face of the post or at or adjacent its lower end.

The invention also provides a method of making such a prosthesis, comprising the steps of: providing a laminate of a foraminous layer of bioabsorbable material and a bioabsorbable film; coating the laminate with a layer of an aqueous gel comprising a bioabsorbable polymer; rolling up the laminate and the gel layer into a spiral roll, followed by drying the gel to form a layer of bioabsorbable sponge. The foraminous layer (2) preferably comprises a synthetic bioabsorbable polymer having high tensile strength. The bioabsorbable film (3) and sponge layer (4) preferably comprise a chemotactic biopolymer such as collagen.
