Abstract: Systems and methods for determining absolute position. A system includes a first bull gear and a second bull gear rigidly connected to the first bull gear. The system includes a first pinion gear rotationally engaged with the first bull gear. The system includes a second pinion gear rotationally engaged with the second bull gear. The system includes a first sensor that senses a first angular position of the first pinion gear. The system includes a second sensor that senses a second angular position of the second pinion gear.

Abstract: Anti-backlash gears and anti-backlash gear systems. A gear includes a plurality of compliant members extending outward to form at least a portion of the gear.

Abstract: A computer-implemented method for collaborative editing of an electronic model of a design object may include (1) identifying clients configured to submit design operations to be performed on a shared design model, (2) receiving, from a first client, a first design operation to be performed on the shared design model prior to receiving, from a second client, a second design operation to be performed on the shared design model, (3) performing the first design operation prior to attempting to perform the second design operation, (4) identifying a conflict between the two design operations, and (5) in response to identifying the conflict between the design operations, notifying the second client that the second design operation was not performed on the shared design model. Various other methods and systems are also disclosed herein.
