Multi-spectral method for detection of anomalies during powder bed fusion additive manufacturing
Embodiments of the systems can be configured to receive electromagnetic emissions of a substrate (e.g., a build material of a part being made via additive manufacturing) by a detector (e.g., a multi-spectral sensor) and generate a ratio of the electromagnetic emissions to perform spectral analysis with a reduced dependence on location and orientation of a surface of the substrate relative to the multi-spectral sensor. The additive manufacturing process can involve use of a laser to generate a laser beam for fusion of the build material into the part. The system can be configured to set the multi-spectral sensor off-axis with respect to the laser (e.g., an optical path of the multi-spectral sensor is at an angle that is different than the angle of incidence of the laser beam). This can allow the multi-spectral sensor to collect spectral data simultaneously as the laser is used to build the part. |

SOTERIA: smart and safe add-on for firearms
Centuries back, guns were means of hunting. Today, these guns fall into the hands of mentally unstable people, causing random acts of violence such as school shootings. There is no meaningful legislation from the government, despite shootings like Sandy Hook and Uvalde. The proposed apparatus will alert the responsible parties when a firearm is in the vicinity of schools and then produce a loud broadcast to deter the perpetrator. The apparatus uses a GPS module that can track the geolocation of the firearm concerning sensitive areas such as schools. The apparatus configures a safety zone, which if breached activates the alert mechanism. These early alerts will provide all the information to schools and local law enforcement to take immediate action and prevent the incident. Tracking, detection, early alerts, and deterrence are the key elements of my apparatus. Hopefully, these safety features can also drive improvement in design of new guns. |

Autonomous auxiliary DEF supply system with purge control
An auxiliary system with purge control automatically supplies diesel exhaust fluid (DEF) to an onboard DEF tank of a diesel engine to enable prolonged unattended operation. The system includes an auxiliary DEF tank, an auxiliary DEF supply line, a controller, a pump, an air inlet, and a three-way valve configured to switch the pump inlet between the auxiliary DEF tank and air. In response to low-level DEF, the pump delivers DEF through the supply line to replenish the onboard DEF tank. The controller may automatically calculate onboard DEF tank volume based on the delivered volume of DEF, and DEF level data received from an ECM, to enable replenishment control regardless of engine make and model. In response to high-level DEF, engine stoppage, or other system fault, the controller switches the valve to air and runs the pump for a predetermined time to purge DEF from the supply line. |

Systems and methods include a computer-implemented method for determining well pressure. Units of pressure-responsive smart polymers are inserted into drilling fluid pumped into a well during a drilling operation. An insertion timestamp associated with each unit is stored indicating times that each unit was inserted.
