Abstract: A cutting tool and an attachment mechanism configured to removably securely couple the cutting tool and a cutting instrument together. The cutting tool comprises a tang end portion, a tip end portion, and a cutting edge on the tip end portion. The attachment mechanism comprises a first and second clamping members with first and second engagement surfaces, respectively. The second clamping member further comprises at least one alignment projections extending and a pair of laterally-spaced projections extending past the second engagement surface. The attachment mechanism further comprises an adjustment mechanism configured to selectively adjust the distance between the first and second engagement surfaces. The tang end portion comprises an axially extending coupling slot and a pair of elastically-deformable securement members at lateral sides that extend laterally outward as they extend axially from the tang end portion toward the tip end portion.

Abstract: Surgical robotic systems and methods that are configured to mitigate and withstand vibration forces. The robotic systems include an articulated arm comprising a plurality of arm segments, and adjustable joints coupled between adjacent arm segments. The robotic systems include an end effector rotatably coupled to an end arm segment comprising a powered drive portion. The end effector comprises a cutting tool attachment mechanism that is configured to couple with a cutting tool such that the cutting tool extends axially therefrom, and the powered drive portion translates the cutting tool along a cutting pathway along which the cutting tool is configured to effectuate cutting that is angled with respect to a longitudinal axis of the cutting tool. The end effector is oriented such that the longitudinal axis of the cutting tool, and that of the end effector itself, are angled with respect to the longitudinal axis of the end arm segment.

Abstract: A method for initiating a time- and geographic-based electronic transaction includes: storing, in a mobile computing device, payment details associated with a transaction account; receiving a payment zone notification upon entry of the mobile computing device into a predefined geographic area, the notification including payment terms; registering a first timestamp upon receipt of the notification; displaying the payment terms; receiving an indication of approval of the payment terms; receiving an exit notification upon exit of the mobile computing device from the predefined geographic area; registering a second timestamp upon receipt of the exit notification; calculating a transaction amount based on an elapsed amount of time between the first timestamp and the second timestamp and a payment rate; and transmitting the calculated transaction amount and payment details.

Abstract: A rotary internal combustion engine includes outer and inner housings defining an enclosure therebetween, and first and second side housings disposed on opposite sides of the outer housing. The inner housing is rotatable relative to the outer housing, at least one retractable barrier and at least one fixed barrier. The at least one retractable barrier and the at least one fixed barrier are disposed in the enclosure so as to divide the enclosure into a combustion chamber and an exhaust chamber. The at least one retractable barrier is mounted along a pivot axis and is pivotable between an extended position and a retracted position. An intake port, exhaust port, and ignition source are also provided. An exhaust duct extends from within the enclosure to outside the outer housing in a direction tangent to flow in the enclosure.
