Abstract: Iron-type golf club heads are disclosed having a heel portion, a sole portion, a toe portion, a top-line portion, a front portion, a rear portion, and a striking face. The iron-type golf club heads include a localized stiffened region that is located on the striking face of the club head such that the localized stiffened region alters the launch conditions of golf balls struck by the club head in a way that wholly or partially compensates for, overcomes, or prevents the occurrence of a rightward deviation. In particular, the localized stiffened region is located on the striking face such that a golf ball struck under typical conditions will not impart a right-tending sidespin to the golf ball.

Abstract: Described herein is a golf club head that comprises a body and a strike plate. The body comprises a heel portion, a sole portion, a toe portion, and a top portion. The strike plate comprises an outer peripheral edge and at least a portion of a strike face. Furthermore, the strike plate is welded to the body via a peripheral weld between the outer peripheral edge of the strike plate and the body. The outer peripheral edge of the strike plate comprises at least one welded portion, welded to the body via the peripheral weld, and at least one non-welded portion, not welded to the body.

Abstract: A shim or badge is affixed to a golf cub body to produce a cap-back iron, giving the appearance of a hollow-body iron. In this way, the golf club can be manufactured with the performance benefits of a game improvement iron, while providing the appearance of a blade, player's iron, and/or a hollow-body iron. For example, by using a lightweight and rigid shim or badge to close a cavity opening and extend into the toe portion in the golf club body, the golf club head can provide increased stiffness in the topline, while lowering CG. Various shim or badge arrangements and materials can be used, and a filler material and/or damper can be included within the cavity to improve sound and feel, while minimizing loss in COR.

Abstract: Disclosed herein is an iron-type golf club head that comprises a strike plate, an enclosed internal cavity, and a rear aperture formed in a rear wall. The iron-type golf club head also comprises a stiffening plug, within the internal cavity and compressed between the back surface of the strike plate and the rear wall. The stiffening plug is insertable, through a rear aperture, into the internal cavity. The iron-type golf club head further comprises a rear fascia covering the rear aperture and at least a portion of the rear wall. A characteristic time (CT) at a geometric center of the strike face is at least 250 microseconds. A maximum thickness of the strike plate, at the strike face, is less than 3.5 millimeters, inclusive. The strike plate, excluding grooves, has a minimum thickness between 1.1 millimeters and 2.2 millimeters.

Abstract: A system for communicating with multiple vehicles or other electronic devices that share a common media access control (MAC) or other address is disclosed. Upon receiving a certificate signing request (CSR) from a connected device and determining that the device does not have a unique address, the system will generate a unique address for the device and embedding the unique addresses in a certificate, sign the certificate, and transfer the certificate to the device. Then, when the system communicates with the device, the system may use that unique address to identify the device.

Abstract: Described herein is a golf club head that comprises a body and a strike plate. The body comprises a heel portion, a sole portion, a toe portion, and a top portion. The strike plate comprises an outer peripheral edge and at least a portion of a strike face. Furthermore, the strike plate is welded to the body via a peripheral weld between the outer peripheral edge of the strike plate and the body.

Abstract: A damper is provided within the cavity of a golf club head and spans substantially the full length of the striking face from heel-to-toe of the golf club head. One or more cutouts and/or other relief is provided in the damper to reduce the surface area of the damper that contacts the rear surface of the striking face. By reducing the surface area that the damper contacts the rear surface of the striking face, the full length damper improves the sound and feel of the golf club head at impact and only minimally reduces performance of the golf club head. For example, the one or more cutouts and/or other relief maintains face flexibility, characteristic time (CT) and coefficient of restitution (COR) of the striking face.

Abstract: The present disclosure relates generally to bicycles. In particular, the present disclosure provides systems and devices for converting a standard bicycle into a cargo bicycle using various detachable components.

Abstract: Iron-type golf club heads can have a high-COR face portion with an optimized face thickness profile that maximizes selected performance characteristics, such as ball speed, ball spin or ball trajectory angle, while maintaining certain required constraint properties, such as keeping stresses low for durability. Such face portions can have certain regions that are significantly stiffer than other regions of the face portion. For example, a low region of the face portion can be significantly stiffer than a high region of the face, or one quadrant of the face can be significantly stiffer than other quadrants of the face. Disclosed face thickness profiles can feature irregularly shaped contours that maximize the distribution of material in the face for optimal performance characteristics within defined constraints.

Abstract: Disclosed herein are embodiments of iron-type golf club heads that comprise weight reducing features in the topline region of the club head that facilitate changing the Z-up location of the club head. In some exemplary embodiments, the body comprises a weight reducing feature in a topline weight reduction zone of the club head that extends over the entire face length from the par line to the toe portion ending at approximately the Z-up location of the iron type golf club head. The weight reducing feature results in a mass savings of about 2 g to about 20 g, and a Zup shift of about 0.5 mm to about 2.0 mm.

The iron-type golf club heads include a localized stiffened region that is located on the striking face of the club head such that the localized stiffened region alters the launch conditions of golf balls struck by the club head in a way that wholly or partially compensates for, overcomes, or prevents the occurrence of a rightward deviation.

Abstract: Clubheads for iron-type golf clubs include a damper positioned within a lower cavity and a weight coupled to the damper and positioned within the lower cavity, wherein the weight is spaced apart from the club head body, or “floating.” The floating weight can be fully supported by the damper and while not contacting any surface of the club head body. Such a floating weight and damper can beneficially affect mass properties of the clubhead, such as Zup, CG, and MOI, without unduly stiffening lower portions of the clubhead, thereby allowing the clubhead to have improved mass properties while maintaining desirable ball-striking properties, such as COR and CT, and also providing damping to improve sound and feel. Some clubheads can also include a dual undercut topline to reduce mass. Some clubheads can also include several raised flats on the rear of the face for improved face thickness measurements.
