Patent number: 11933864Abstract: A system and method of effectively measuring a change in a gradient of a magnetic field. The systems include a first magnet and a second magnet mechanically coupled together and aligned along a polarization axis. The first magnet and the second magnet are positioned such that a pair of like magnetic poles of the first magnet and the second magnet face in opposite directions. Further, the first magnet and the second magnet are configured to move along the polarization axis in response to a magnetic field. A sensing system is configured to measure a change in a gradient of the magnetic field based on the movement of the first magnet and second magnet along the polarization axis in response to the magnetic field.Type: GrantFiled: May 18, 2023Date of Patent: March 19, 2024Assignee: Trustees of Boston UniversityInventors: Joshua Javor, David Bishop, David Campbell, Matthias Imboden

Patent number: 11932503Abstract: A proppant delivery assembly receives and supports a plurality of containers having proppant stored therein. A cradle has a top surface which receives and supports the plurality of containers when positioned thereon. The cradle enables the plurality of containers to dispense the proppant stored therein. A proppant mover is positioned to underlie and extend along the top surface of the cradle aligned with the plurality of containers to receive proppant from the plurality of containers. The proppant mover carries proppant away from the plurality of containers. A chute is coupled to the cradle for receiving proppant from the proppant mover and directing the proppant to a blender hopper. A hood assembly is disposed at an end of the chute opposite the proppant mover for directing a vacuum air flow that removes a volume of air containing proppant dust particles directed from the chute.Type: GrantFiled: August 15, 2022Date of Patent: March 19, 2024Assignee: SANDBOX ENTERPRISES, LLCInventors: Joshua Oren, Marty Boros, Pete Berveiler, Dave Hansen, Colin Campbell, Mike Edwards, Thomas Massalone

Patent number: 10639204Abstract: A navigation and monitoring system to track positions of surgical components during surgery of a patient. Some embodiments include a power source to emit a tracking signal during surgery of the patient, a first sensor mounted to a region of the patient to respond to the emitted tracking signal, and a control unit to track a position of the region relative to a fixed region of the patient as the region moves with respect to the fixed region, based on the response of the first sensor. The system can calibrate and register a movable reference point of the patient relative to a fixed reference point, and can maintain that reference point when the movable reference point moves in space during a surgical process.Type: GrantFiled: October 9, 2015Date of Patent: May 5, 2020Assignee: X-Nav Technologies, LLCInventors: Andrew Cheung, Joshua Campbell

Patent number: 10542071Abstract: Techniques are disclosed for monitoring the health of a computing application, system or service. A health monitoring service performs event driven health status checks for applications that use non-HTTP workloads. To do so, heath status messages (e.g., HTTP status requests) are directed to an API gateway at a specified frequency. In response to each health status message, the API gateway triggers at least a first event driven function to perform a health check of an application. Results of the health-status check performed by the first event driven function may be written to a status database. Further, results of the first event driven function can result in additional event driven functions being triggered (e.g., to remove an unhealthy application from production use).Type: GrantFiled: September 27, 2016Date of Patent: January 21, 2020Assignee: Amazon Technologies, Inc.Inventors: Nicholas Channing Matthews, Joshua Campbell

Patent number: 9579580Abstract: A simulated eye is provided for taxidermy, replica animals made by carving wood, modeling, and other replica animal or replica human construction. The simulated eye provides a more realistic appearance than previous simulated eyes. The eye includes a domed central portion resembling a cornea that is surrounded by a scleral band. The eye is made from one-piece construction using materials that simulate the refractive index of a natural eye. The interior of the eyes are painted to resemble the iris and pupil of a real eye. The configuration of the simulated eye, in conjunction with the refractive index of the material with which it is made, provides a realistic appearance as the angle at which the eye is viewed changes. The eye is structured for easy mounting.Type: GrantFiled: December 13, 2013Date of Patent: February 28, 2017Inventors: Joshua Campbell, Jason Campbell
