Patent number: 10349940Abstract: An apparatus includes a housing, a platform, a buttress assembly, at least one retainer member, and an indicator. A portion of the platform is exposed in a gap defined by the housing. The buttress assembly is exposed in the gap defined by the housing. The retainer member is configured to selectively retain the buttress assembly against the platform. The retainer member is further configured to release the buttress assembly from the platform in response to a clamping action of an end effector positioned in the gap defined by the housing. The indicator is configured to provide indication of a state of one or both of the buttress assembly or the at least one retainer member. The indicator is further configured to change state in response to a change of state of one or both of the buttress assembly or the at least one retainer member.Type: GrantFiled: October 29, 2015Date of Patent: July 16, 2019Assignee: Ethicon LLCInventors: Mark S.

Patent number: 10322501Abstract: A fastening tool and method of operating a fastening tool can include a driver, a motor, a flywheel driven by the motor, an actuator, and a controller. The actuator can cause the driver to engage with the flywheel to cause the driver to move along an axis. The controller can selectively operate the motor and selectively operate the actuator. In a first state, the controller will not operate the actuator unless the contact trip switch and the trigger switch are both actuated, the contact trip switch being actuated prior to actuation of the trigger switch, and the flywheel is rotating at a first predetermined speed. When the controller is in the first state, the controller can operate the motor to rotate the flywheel at a second predetermined speed until the earlier of a second predetermined period of time after operation of the actuator, or a subsequent operation of the actuator.Type: GrantFiled: January 13, 2016Date of Patent: June 18, 2019Assignee: Black & Decker Inc.Inventors: Stuart E. Garber, Dean R. Edwards
