Weight adjustable golf club head

A weight adjustable golf club head is provided. The club head has a trough at a lower part of the club head's back and a weight positioned inside the trough. The trough is arranged to follow the curvature of the club head's bottom. The trough has a tapered mouth along the surface of the club head and a base. There is an insertion hole at a position along the trough. The weight could be inserted into the trough through the insertion hole, and then slid along the trough. The weight contains a seat, a bolt, and a loading ring. The seat has a locking rim and the positioning rim which are inside the trough's base and mouth respectively when the weight is slid into the trough. The seat's body and the locking rim have a number of breaks so that the locking rim could be stretched. When the bolt is screwed into or out of the seat, the locking rim would be stretched or retracted, so that the weight could be locked or un-locked in the trough. The loading ring is put around the seat and could be made of various types of material. By adjusting the position of the weight along the trough and changing the loading ring, the club head's center of gravity could be adjusted to suit a golfer's specific stance, habit, and the specific trajectory required.

Golf club head with high center of gravity

A golf club head is formed of a hollow metal body having a center of gravity that is above the geometric center of the club face. The hollow metal body of the club head has a sole plate that is smoothly contoured and devoid of any inefficient structures such as weight pads or other mass concentrations. By avoiding the use of inefficient structures such as weight pads, more material is available for the structural walls of the club head body while maintaining the club head within acceptable weight limitations. Moreover, placement of the center of gravity above the center line of the face ensures that sufficient backspin will be imparted to the golf ball when struck by the club.

Nasal cannula assembly

A nasal cannula assembly designed for contact with the nasalabidial area of a patient's face comprising a nasal cannula, a pair of oxygen supply tubes connected to opposite ends of the nasal cannula and a main oxygen supply line. The nasal cannula is made of a flexible plastic material molded into a light-weight hollow tubular member having a main body portion formed at an acute angle in the center and having a pair of spaced exterior orifices projecting from the body at an angle and curved upwardly and inwardly for directing gas flow into a patient's nostrils. Attachment points for oxygen supply tubes are above center of gravity of the nasal cannula to make it self-righting thus eliminating need for stiff supply tubing to orient cannula. Oxygen supply tubes made from ultra-high molecular weight PVC possess superior flexibility and low compression set so that little tension on the tubing is required to hold cannula in proper position. A main oxygen supply line made from ultra-high molecular weight PVC resists the formation of twisted loops that tend to block oxygen flow.

Golf club head

A golf club head comprising an outer shell and a strike plate having a strike face. The outer shell and the strike face define a club head volume. A heel / toe axis extends through the center of gravity of the club head. The heel / toe axis is generally parallel to the strike face and generally horizontal relative to a ground plane when the club head is at an address position. The rotational moment of inertia about the heel / toe axis is related to the club head volume by the equation Ixx ≧,46*HV+77, where Ixx is the rotational moment of inertia about the heel / toe axis in units of kg-mm2 and HV is the club head volume in units of cm3.

Post patch assembly for mounting devices in a tire interior

A modular electronic assembly for integration with a pneumatic tire includes a mounting patch, a power source, and at least one electronic device supported by a substrate. The mounting patch is preferably adapted for positioning on the inner liner of a pneumatic tire, and the power source is at least partially embedded in the mounting patch. Such embedded positioning of the battery results in an overall structure with a lower center of gravity than previous tire electronics assemblies, thus having increased mechanical stability and survivability in a tire environment. Electronic device(s) supported on the substrate may receive power from the power source, which in some embodiments corresponds to one or more batteries. The substrate supporting the at least one electronic device may be attached to the mounting patch by a variety of fashions. Exemplary attachment configurations may correspond to an adhesive layer, a hook and loop tape combination, or physical interconnection via terminals extending from the power source through the support substrate. Exemplary electronic devices may include such components as condition-responsive devices including transducers, acoustic devices, sensors, etc. for sensing certain environmental conditions such as temperature and / or pressure, tire revolution counters, vehicle speed sensors, sidewall deflection sensors, tire displacement sensors, microprocessors, memory modules, RFID transponders, light assemblies, data transmitters and / or receivers, and power, supply components. Selected of the electronic devices (including one or more antennas associated with any RF devices) may be encapsulated by a non-conductive rubber or elastic material to facilitate effective transmission characteristics. Conductive springs, flexible conductive elastomer or fatigue-resistance metal may be used to interconnect various electronic components (such as an RF device to an antenna).

Transitioning hollow golf clubs

The present invention relates to a set of golf club irons in which some of the club heads have a hollow space, and some of the club heads do not have a hollow space. The hollow space is preferably defined by a lower portion of the front face, a portion of the sole, and a rear wall. The presence of the hollow space moves the club head center of gravity back (away from the face) and down (toward the sole), making it easier to get a golf ball airborne. The volumes of the hollow spaces generally transition or get progressively smaller with an increase in the club loft angle, thus altering the center of gravity location and moments of inertia by different amounts for different clubs. The hollow spaces may be empty or filled, in whole or part.

Adjustable weight golf clubs

The present invention relates to golf clubs having a movable weight which may be used to adjust the center of gravity of the golf club head. The golf club may include a slidable weight movable to various positions along a slot between the heel and the toe of the club. The head may include a cavity shaped to receive an insert. In one embodiment, a slidable weight consisting of a screw and a weight which may engage with each other may be configured to move along the length of the insert. During assembly, the weight may be inserted into an opening in the end of the insert and slid along a close fitting channel running the length of the insert. The weight's position along the channel may be secured by engaging the screw and tightening down the screw with a portion of the insert secured between the screw head and the weight. The assembled insert and slidable weight may then be press fit into the cavity in the head. By adjusting the position of the weight and screw within the insert, the center of gravity of the golf club may be adjusted.

The sensor measures the direction and rate of shift of the center of gravity and mass shift of the human and creates a representative input signal. The controller determines the appropriate outputs in response to the relative center of gravity shift data received. The dynamically adjustable vehicle system receives the controller output and performs the expected action.
