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 first base station receives from a second base station, a handover request message comprising traffic pattern parameters of a wireless device. The traffic pattern parameters comprise a first traffic periodicity, a first timing offset, and a first message size. A handover request acknowledge message indicating at least one periodic resource configuration parameter determined based on the first traffic periodicity is sent to the second base station. A random access preamble associated with a handover of the wireless device is received from the wireless device. The first base station determines a resource block assignment based on the first message size. A control command is transmitted to the wireless device. The control command indicates: activation of radio resources associated with the at least one periodic resource configuration parameter; and the resource block assignment.

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.

A drive element is described for transmitting a torque to a threaded insert sleeve. A holder has a drive profile in which along a longitudinal axis of the drive element a drive tool for transmitting a torque from the drive tool to the drive element can be received. The longitudinal axis passes through the center of the drive profile and corresponds to a rotation axis of the drive element about which the drive element rotates when transmitting the torque from the drive tool to the drive element. An axial connecting section has an outer surface for forming a connection to the threaded insert sleeve that is one or more of a materially bonded, form-fitting and force-fitting connection. Via the outer surface, when a connection to a threaded insert sleeve is formed, a torque can be transmitted from the drive element to the threaded insert sleeve.

In one embodiment, a handheld stud remover and in a second embodiment, a modified hex nut metal stud remover. In addition, there is a method of removing metal studs or bolts from threaded openings using the handheld stud remover and a method of removing metal studs or bolts from threaded openings using a modified hex nut metal stud remover.

A screwdriver assembly includes a screwdriver shaft and an insert. The screwdriver shaft extends longitudinally from a proximal end to a distal end and having a longitudinal channel extending therethrough. The insert has a longitudinal shaft received within the longitudinal channel and a distal end extending distally relative to the distal end of the screwdriver shaft. The insert shaft is rotatable relative to the screwdriver shaft. The distal end of the insert is sized and shaped to engage a head of a screw. The distal end of the insert is disengaged from the screw head by rotating the insert relative to the screwdriver shaft.

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.
