Abstract: Woodworking machines are disclosed having a blade adapted to cut workpieces, and an actuating mechanism operable to move the blade toward the workpiece. The machines also include a detection system configured to detect one or more dangerous conditions between a user and the blade, and a reaction system configured to stop the movement of the blade toward the user upon detection of a dangerous condition by the detection system.

Abstract: A miter saw is disclosed having a base, a blade supported by the base, a detection system adapted to detect a dangerous condition between a person and the blade, and a reaction system associated with the detection system to cause a predetermined action to take place upon detection of the dangerous condition. The blade is rotatable, and moves into a cutting zone to cut a workpiece. The predetermined action may be to stop the blade from rotating, to create an impulse against movement of the blade into the cutting zone, or to cause the blade to move away from the cutting zone.

Abstract: Bone fixators for securing and/or repairing fractures and/or other defects of a distal radius and wrist. The bone fixators may include, among others, (1) a distal mounting element configured to be mounted in a metacarpal bone, or other hand bone, (2) a proximal mounting element configured to be mounted in the radius, the ulna, or other arm bone, (3) a distal member configured to be secured to the distal mounting element, (4) a proximal member configured to be secured to the proximal mounting element, and/or (5) a coupling, connecting the proximal member and the distal member, configured to allow immobilization, as well as adjustable flexion, rotation, and/or translation of the distal member relative to the proximal member.

Abstract: Systems, including apparatus, methods, and kits, for fusing two or more bones with a bone plate.

Abstract: Systems, including apparatus and methods, for repairing injured connective tissue. These systems may include, among others, a surgical stapler and staples for repairing partially or completely severed tendons and/or ligaments.

Abstract: Bone plates configured to be deformed after the bone plates have being secured to bone, apparatus including the bone plates, and methods of using the bone plates to fix bones.

Abstract: A system, including method, apparatus, components, and kits, for guiding a hole-forming tool and/or a fastener through a bone and then to a bone-repair device that is connected to the bone.

Abstract: Bone plates having an adjustable joint, and methods of using the bone plates to fix bones.

Abstract: Bone plates having slots configured to permit positioning of the bone plates on bone, and methods of using the bone plates for bone fixation.

Abstract: Bone plates having reference marks, and methods of using the bone plates to fix bones.

Abstract: A miter saw is disclosed having a base, a blade supported by the base, a detection system adapted to detect a dangerous condition between a person and the blade, and a reaction system associated with the detection system to cause a predetermined action to take place upon detection of the dangerous condition. The blade is rotatable, and moves into a cutting zone to cut a workpiece. The predetermined action may be to stop the blade from rotating, to create an impulse against movement of the blade into the cutting zone, or to cause the blade to move away from the cutting zone.

Abstract: A system and method for installing a shoulder prosthesis. The method includes removing the original humeral head and shaping the proximal end of the humerus with one or more implements to prepare the humerus to receive the shoulder prosthesis.

Abstract: A machine such as a saw, jointer, planer, etc. is disclosed. The machine has cutting tool, a direct drive mechanism configured to move the cutting tool, a detection system adapted to detect the occurrence of an unsafe condition between a person and the cutting tool, and a reaction system adapted to mitigate the unsafe condition upon the detection of the unsafe condition by the detection system. An electrical signal is imparted on the cuffing tool, and the signal is used to determine the occurrence of the unsafe condition. The direct drive mechanism is electrically isolated so that the electric signal may be imparted on the cutting tool. The electric isolation may be achieved through configurations such as insulated bearings, a substantially non-conductive housing, and a substantially non-conductive coupling joining two shaft portions.

Abstract: Band saws with high-speed safety systems are disclosed. The band saws include a detection system adapted to detect a dangerous condition between a blade and a person. A reaction system performs a specified action such as stopping the blade upon detection of the dangerous condition.

Abstract: A method of fusing a joint between two bones, comprising boring a hole through one of the bones across the joint therebetween and into the other bone, placing the leading end of a screw into the hole, where the screw has a threaded region having a pitch that is larger toward a leading end of the screw and smaller toward a trailing end of the screw, and driving the screw into the bone until the threaded region spans the joint.
