Systems for distracting a facet joint and positioning a permanent implant in the joint are disclosed. The implants serve to retain a distracted position of the facet joint which is achieved with positioning of the leading end of a distraction tool in the facet joint and then distracting or enlarging the joint a desired amount. The permanent implant could be part of the distraction mechanism which can be separated from the delivery tool once the joint has been distracted or an auxiliary implant may be positioned before the distraction mechanism is removed from the distracted joint. The permanent implants can be solid, mechanical devices that may have fixation means thereon to hold them in place or injected fluids such as hydrogels or fluids confined within balloons.

A foot positioning aid is disclosed for guide proper positioning of a player's feet for a sport stance. The aid has two foot targets each with a top side, an underside, and a perimeter edge. The foot targets are separate from one another for independent positioning and placement on a playing surface. A securement device on the underside of each of the foot targets is configured to removably retain the foot targets in a selected location on the playing surface during use. The player places their feet on the top sides, one on each of the foot targets during use.

A golf training device for aiding a golfer in perfecting their grip on a golf club and their swing. The golf training device includes an elongated member made from a flexible plastic material and that is designed to frictionally engage the handle portion of the golf club. The device includes a gripping region with first and second positioning aids thereon for correct placement of the golfer's thumbs. The device further includes a pair of lasers that are mounted in a rest area that integrally formed with the gripping region. The lasers are mounted so as to emit a pair of divergent laser beams outwardly away from the lowermost end of the device and on either side of the golf club head. The lasers are used to correctly align the device on the golf club shaft and as an aid for the golfer to check his grip on the club and the position he assumes for addressing a golf ball. The device may further be provided with a third laser mounted on the uppermost end of the gripping region such that the third laser emits a beam of light outwardly from the uppermost end and aligned with the longitudinal axis of the device. The third laser beam is useful for the golfer to train himself to correctly swing the golf club.

A valve train for an internal combustion engine is provided, with the valve train having a switchable rocker arm assembly (1) with a plurality of rocker arms (6, 7, 8) for activating at least one gas exchange valve (2), and also having at least one camshaft (3) with differently contoured cams (4, 5) through which different adjusting displacements can be imparted to individual rocker arms of the rocker arm assembly (1). The assembly further includes a switching device (9) for selectively activating the rocker arms for driving the gas exchange valve (2) with a varying valve lift. To create a valve train in which individual gas exchange valves can be operated in different modes of operation with only a small amount of construction work and expense, the rocker arm assembly (1) has a stationary rocker arm shaft (10) on which at least two outer rocker arms (6, 7), that are in continuous contact with associated, differently contoured cams (4, 5), and a center rocker arm (8) with a lever arm extension (11) through which the gas exchange valve (2), in operative connection to one of the two outer rocker arms (6, 7), can be selectively actuated, are mounted for tilting movement. Actuatable locking pins (12, 13) are arranged on the outer rocker arms (6, 7) for sliding axially parallel to the rocker arm shaft (10), a locking pin receiver (14) is arranged on the center rocker arm (8) and positioning aids (15, 16, 17) are arranged on the outer and the center rocker arms (6, 7, 8), so that the center rocker arm (8) can be selectively force-locked to one of the two outer rocker arms (6, 7) or be deactivated.

The invention discloses a positioning method, device and system, a terminal, an LMF entity and a medium, which are used for solving the problem of low UE-based OTDOA positioning precision in the priorart. The method comprises the steps that a terminal sends a positioning assistance data requesting message to a local management function (LMF) entity, wherein the positioning assistance data requesting message comprises first identification information of a beam reference signal detected by the terminal; receiving positioning assistance data which is sent by the LMF entity and contains beam direction information of a beam reference signal of second identification information, wherein the second identification information is identification information of a beam reference signal sent by a neighboring base station that can be detected by the terminal determined by the LMF entity according to the first identification information; and determining each RSTD of the beam reference signals of thefirst identification information and the second identification information, and determining position information of the terminal according to each determined RSTD and the beam direction of each beamreference signal.

A local coil arrangement for magnetic resonance applications has a mechanically dimensionally stable support element that rests on a patient bed so as to transfer the weight of the local coil arrangement to the patient bed. The local coil arrangement has at least one local coil to excite and / or to receive magnetic resonance signals and a multipole, prefabricated electrical interface via which the local coil can be electrically contacted. The electrical interface is arranged so as to be dimensionally stable at the support element. Positioning aids for positioning of local coil arrangement are arranged on the support surface that also transfer the weight of the local coil arrangement is transferred to the patient bed as well as plugging the electrical interface into an electrical counter-interface.
