A tool for unscrewing a stud has a body with cam surfaces in a bore. A recess extends through the cam surfaces. Jaws have outer sides in engagement with one of the cam surfaces and inner sides containing teeth. An outward protruding rib on the outer side of each of the jaws inserts into the recess. Rotation of the body in a first direction causes the cam surfaces to slide in the first direction along the outer sides of the jaws, pushing the jaws to a gripping position. Rotation of the body in a second direction causes the cam surfaces to slide in the second direction along the outer sides of the jaws, enabling the jaws to move to a retracted position.

A method may include receiving, by a first base station from a second base station, a handover request message comprising traffic pattern parameters of a traffic of a wireless device, the traffic pattern parameters comprising a first traffic periodicity, a first timing offset, and a first message size. The method may also include sending, to the second base station, a handover request acknowledge message indicating at least one periodic resource configuration parameter for the wireless device. The method may further include receiving, from the wireless device, a random access preamble associated with a handover of the wireless device. The method may additionally include transmitting, to the wireless device, a control command indicating activation of radio resources associated with the at least one periodic resource configuration parameter and indicating a resource block assignment for transmission of the traffic of the wireless device.

A screw magazine having a loading end for receiving a collated strip of screws. The magazine includes a pusher that urges screws of a collated strip toward a discharge end of the magazine. A bit opening at a top and at the discharge end of the magazine is configured to receive a drive bit for driving the at least one screw through a discharge opening at a bottom of the magazine body. Also provided is a collated scrip of screws including a plurality of screws coupled to a rigid support configured to be held in a hand of a single user to allow driving of the screws with the other hand.

The present disclosure relates to systems and methods for affixing and/or removing a fastener from a wafer-carrying pod. The system includes a robotic arm with a screw tool assembly disposed at the far end of the robotic arm. The screw tool assembly includes a lower sleeve configured to receive a fastener. A screwdriver is disposed within an upper sleeve of the screw tool assembly, and a motor is provided to rotate the screwdriver. In use, the screw tool assembly is positioned over the fastener so the lower sleeve surrounds the fastener and the screwdriver engages the fastener. The screwdriver unscrews the fastener from the pod, and the fastener head is received within the lower sleeve.

An adjustable socket assembly includes a collet having a first end, a second end, and a perimeter wall. The second end has a receiving aperture therein. The collet is divided into a plurality a plurality of sections. A sleeve has a bottom end that receives the collet. The sleeve has an interior surface that tapers inwardly and abuts the sections to move toward each other as the sleeve moves toward the second ends of the sections. A biasing member extends through a top end of the sleeve and engages each of the sections. The biasing member is actuated to bias the sleeve downward to close together the sections and engaged the valve actuator. An engagement head is attached to the upper end of the biasing member and engages a tool to rotate the collet.

A hand tool includes a handle, at least one driving head, at least one groove and at least one abutting element. The at least one driving head is connected with at least one end of the handle. The at least one groove is disposed on an inner edge of the at least one driving head, and includes an inner wall and at least one margin structure. The at least one margin structure extends from an end of the inner wall, and an angle is between the at least one margin structure and the inner wall. The at least one abutting element is disposed on the at least one groove.

A compression screw driver system including a drive member having a shaft extending from a proximal end to a distal end. A drive selection member is positioned about the shaft and is axially moveable along the shaft between an engagement position and a disengaged position. A distal portion of the drive selection member defines a first engagement structure. A compression sleeve is positioned over the distal end of the shaft. The proximal end of the compression sleeve defines a second engagement structure which complements the first engagement structure and the distal end of the compression sleeve defines a contact surface. In the engagement position the first and second engagement structures are engaged and the compression sleeve rotates with the drive member and in the disengaged position the first and second engagement structures are disengaged and the compression sleeve remains stationary while the drive member rotates.
