  • Patent number: 11963750
    Abstract: A system for non-invasive hematological measurements includes a platform to receive a body portion of a user and an imaging device to acquire a set of images of a capillary bed in the body portion. For each image, a controller detects one or more capillaries in the body portion of the finger to identify a first set of capillaries by estimating one or more attributes of each capillary (e.g., structural attributes, flow attributes, imaging attributes, or combinations thereof), wherein at least one attribute of each capillary meets a predetermined criterion. The controller also identifies a second set of capillaries from the first set of capillaries such that each capillary of the second set of capillaries is visible in a predetermined number of images of the set of images.

  • Patent number: 11931956
    Abstract: This invention teaches a multi-sensor quality inference system for additive manufacturing. This invention still further teaches a quality system that is capable of discerning and addressing three quality issues: i) process anomalies, or extreme unpredictable events uncorrelated to process inputs; ii) process variations, or difference between desired process parameters and actual operating conditions; and iii) material structure and properties, or the quality of the resultant material created by the Additive Manufacturing process. This invention further teaches experimental observations of the Additive Manufacturing process made only in a Lagrangian frame of reference. This invention even further teaches the use of the gathered sensor data to evaluate and control additive manufacturing operations in real time.

  • Publication number: 20240085336
    Abstract: This disclosure describes various system and methods for monitoring photons emitted by a heat source of an additive manufacturing device. Sensor data recorded while monitoring the photons can be used to predict metallurgical, mechanical and geometrical properties of a part produced during an additive manufacturing operation. In some embodiments, a test pattern can be used to calibrate an additive manufacturing device.

  • Publication number: 20240087684
    Abstract: Methods and systems for designing phage therapy cocktails. A candidate phage selector module may be configured to predict lytic activity of phages using a first trained machine learning algorithm, and select candidate phages based at least in part on predicted lytic activity. A cocktail generator module may be configured to generate a set of phage cocktails using a second trained machine learning algorithm, based at least in part on predicted lytic activity. A feedback panel module may be configured to receive feedback information associated with phage cocktails, and use the feedback information to train the first and/or second trained machine learning algorithms.

  • Patent number: 11692876
    Abstract: An optical manufacturing process sensing and status indication system is taught that is able to utilize optical emissions from a manufacturing process to infer the state of the process. In one case, it is able to use these optical emissions to distinguish thermal phenomena on two timescales and to perform feature extraction and classification so that nominal process conditions may be uniquely distinguished from off-nominal process conditions at a given instant in time or over a sequential series of instants in time occurring over the duration of the manufacturing process. In other case, it is able to utilize these optical emissions to derive corresponding spectra and identify features within those spectra so that nominal process conditions may be uniquely distinguished from off-nominal process conditions at a given instant in time or over a sequential series of instants in time occurring over the duration of the manufacturing process.

  • Patent number: 11498498
    Abstract: A steering roll connector assembly includes a roll stator. The assembly also includes a roll rotor telescoped in and rotatably coupled to the roll stator to allow relative rotation between the roll rotor and roll stator. The assembly further includes a lock-pin operatively engaging the roll rotor, and the lock-pin is releasable from the operative engagement with the roll rotor. The assembly yet further includes an arm extending from the lock-pin and operatively engaging the roll stator when the lock-pin couples to the roll rotor to prevent relative rotation between the roll rotor and the roll stator.
