  • Patent number: 10346898
    Abstract: The computer-implemented purchased part order data management system employs a database management computer hosting a purchased part order database and an automated data collection and review computer communicating with the database management computer. The data collection and review computer has a purchased part order data (PPOD) repository and a messaging system that includes a message routing data structure. Through an interface, a user interacts with the data collection and review system to add PPOD information, which is then made available to other users for review. The data collection and review computer records the status of the PPOD as it undergoes the review process and mediates which party is next invited to review the PPOD information. Once finally reviewed, the automated data collection and review computer issues a prompt to the database management computer to ingest information based on the PPOD.

  • Patent number: 10161495
    Abstract: Mating bevel gears generally include a pinion gear having a body that rotates about an axis and a side gear having a body that rotates about an axis that intersects the axis of the pinion gear. Pinion gear teeth of the pinion gear have a side that defines a curvature with an involute section through which a pitch line extends and a parabolic shape between the pinion gear teeth. Side gear teeth of the side gear have a side that defines a curvature with an involute section through which a pitch line extends and a parabolic shape between the side gear teeth. The curvatures on the pinion and the side gear teeth cooperatively define a controlled relative radius of curvature section except where the involute sections are located. The controlled relative radius of curvature section defines a sum of values of radius of curvature at a point of contact between the curvatures of the pinion gear teeth and the side gear teeth. The sum has a constant or decreasing value.
