A temporary shaft-component connection for assembling a selected golf club shaft with a club head and / or hand grip segment, to facilitate custom club design and fitting to suit the needs and preferences of an individual golfer. The temporary shaft-component connection is particularly designed for use with nonmetallic club shafts formed from a graphite-based composite material or the like having a range of different lengths and stiffness (whip) characteristics. The temporary connection includes an adapter insert for slide-fit reception into an adapter socket, wherein the adapter insert and socket include interengaging flat surfaces such as splines to prevent relative rotation therebetween. The adapter insert is mechanically seated and secured relative to the adapter socket at a pair of axially spaced locations, with a resilient compressible anchor member disposed at one of these securement points for substantially eliminating undesired intercomponent movement.

The user can print a series of print object directly onto the permanent print surface coating of the coated print bed, without having to refresh or refurbish the print surface, such as by applying to the print bed surface a temporary coating such as painter's tape, or a liquid adhesive.

In representative embodiments, the present invention is directed to an at least partially in-the-canal module. The module may include a speaker module that generates audio signals from an electrical driving signal. The speaker module has a tubular body with a diameter that is smaller than the ear canal of the user. The speaker module also includes an arcuate raised ridge. A cushion tip of deformable material may be used to enclose the speaker module within a tubular portion that applies an elastic force to the arcuate raised ridge to prevent removal of the speaker from the cushion tip. Also, the tubular portion is longer than the speaker module to cause the cushion tip to deflect during navigation through the canal. Further, the tip portion of the cushion tip possesses sufficient structural rigidity to prevent the speaker from being pushed through the cushion tip during navigation through the canal.

Devices and methods are disclosed for the treatment or repair of regurgitant cardiac valves, such as a mitral valve. An illustrative annuloplasty device can be placed in the coronary sinus to reshape the mitral valve and reduce mitral valve regurgitation.

A catheter with basket-shaped electrode assembly with spines configured for hyper-flexing in a predetermined, predictable manner when a compressive force acts on the assembly from either its distal end or its proximal end. At least one spine has at least one region of greater (or hyper) flexibility that allows the electrode assembly to deform, for example, compress, for absorbing and dampening excessive force that may otherwise cause damage or injury to tissue wall in contact with the assembly, without compromising the structure and stiffness of the remaining regions of the spine, including its distal and proximal regions. The one or more regions of greater flexibility in the spine allow the spine to flex into a generally V-shape configuration or a generally U-shape configuration.

A wear member for attachment along the digging edge of excavating equipment that includes ridges formed along its front working end. As the front end wears away, the tips of the ridges along the front of the wear member project forward to define a serrated penetrating edge. A serrated front edge is able to more easily cut into and through the ground. The ridges may be arranged in a generally axial direction along the front working end to present a reduced surface area to contact the ground for easier penetration. The ridges provide the front working end with sufficient rigidity and strength without unduly enlarging the surface area of the penetrating edge that initiates contact with the ground.
