摘要： The present disclosure relates to the generation of an activated platelet product in which one or more of the presence or absence of clots, the timing of clot formation (if present), and/or the mechanical strength of clots (if present) is controlled by the presence or concentration of calcium ions during the activation process. In certain embodiments, the calcium ion concentration is controlled in the presence of pulsed electric fields or a chemical activator (e.g., thrombin) as part of the activation process.

摘要： A sensor system includes a sensor network comprising at least one optical fiber having one or more optical sensors. At least one of the optical sensors is arranged to sense vibration of an electrical device and to produce a time variation in light output in response to the vibration. A detector generates an electrical time domain signal in response to the time variation in light output. An analyzer acquires a snapshot frequency component signal which comprises one or more time varying signals of frequency components of the time domain signal over a data acquisition time period. The analyzer detects a condition of the electrical device based on the snapshot frequency component signal.

摘要： A system for use in maintaining a pipe having a sidewall is provided. The system includes a motorized apparatus sized to fit within the pipe and configured to travel along the pipe through an interior cavity. The motorized apparatus includes a plurality of leg assemblies each including a first leg portion, a second leg portion, and a joint rotatably coupling the first leg portion to the second leg portion. A drive mechanism coupled to the joint is configured to interact with the sidewall. The system also includes an actuator assembly configured to independently position each leg assembly relative to a body assembly to adjust a radial position of the joint of the associated leg assembly relative to the body assembly. The system also includes a controller configured to send instructions to the actuator assembly based at least in part on at least one of a dimension of the interior cavity and a desired force on the sidewall.

摘要： The disclosure relates to an apparatus for manufacturing a metallic component, and corresponding methods. The apparatus may include a build plate with a build surface and an aperture. The apparatus may also include an actuator operable to translate a metallic component such that an end portion of the metallic component is positioned within the aperture of the build plate and below the build surface. The apparatus may further include a seal coupled within the aperture of the build plate and configured to engage the end portion of the metallic component. The aperture of the build plate, the seal, and the end portion of the metallic component may cooperate to form a powder bed to hold metallic powder therein. The apparatus may also include an external heat control mechanism operable to form a predetermined temperature profile of the end portion of the component to prevent cracking of the component.
