摘要:
A golf ball is provided that has a hard sphere core or layer that exhibits a controlled vibrational response. The vibrational response may be controlled by tailoring the stiffness or damping of the sphere with at least one element, such as a groove(s) or any other type of indentation in the hard sphere core. The groove (or grooves) serves to locally reduce the wall thickness of the hollow metal sphere core, thereby reducing the stiffness of the core by allowing larger deformations under a load without significantly reducing the total mass of the core. This results in a golf ball that is legal for play and capable of drive distances essentially equivalent to those of currently available high performance golf balls, but that also maintains a high moment of inertia, allowing less hooks and slices during play.

A method for the manufacture of hollow metal spheres is provided. The method includes stamping appropriately-shaped hemispherical components and subsequently laser welding of the hemispheres. Metal spheres made by the method of the invention are substantially uniformly symmetrical in their mass distribution, and can provide superior performance in applications, such as golf ball cores and light-weight ball bearings.

A golf ball is provided. The golf ball includes a hollow metal core made from a work-hardened metal alloy. The golf also includes a mantle layer enveloping the metal core. The mantle layer may be made from a mixture of long-ball resin and soft-ball resin. The golf ball further includes a cover positioned about the mantle layer to protect the mantle layer. A method of manufacturing the golf ball is also provided.

A precipitation gauge for measuring liquid and frozen precipitation is provided according to the present invention that includes a support structure having at least one light sensor, or pair of electrodes, and at least one light source disposed thereon so that the light sensor may receive light that is emitted from the light source. The light sensor or light sensors and the light source or light sources generally extend a substantial height of the support structure. The light sensor or light sensors generate an output signal in response to the amount of light received from the light source. A microprocessor receives the output signal or output signals from the light sensor or light sensors and determines whether precipitation is present between the light sensor or light sensors and the light source or light sources. Based on the output signal or output signals, the microprocessor determines and displays the level of precipitation. The microprocessor may also determine the density of frozen precipitation.

The present invention is directed to a golf ball (1) having one or more nanostructured materials, i.e., materials with at least one dimension in the 1-100 nm range. The nanostructured materials are present within the hollow metal core (3), a surrounding polymer layer (4), or both. More particularly, the golf ball (1) may include a sphere comprising a nanostructured steel, a polymer comprising a nanoclay material, or both, which improve durability and performance. The present invention is also directed to a method for making the improved golf ball.

A clothing garment is constructed to include adjustable sections that allow for the convenient adjustment of length of sections of the garment so that the useful fitted lifetime of the outfit may be extended. Preferably the method of adjustment includes zippers, Velcro-type materials, buttons, snaps including metallic or plastic snaps, magnets, or any other mechanism that may be used to conveniently attach and detach sections of clothing from each other. The construction may be used on a wide variety of clothing articles, but is particularly useful for children's clothing.

A remotely controlled brake actuator system for use with a wheeled vehicle includes a remote wireless transmitter, a wireless receiving and control unit to receive signals from the wireless transmitter, a vehicle-mounted braking arrangement, and an electronic controller operative to process signals the wireless receiver receives and to deliver electrical signals to the braking arrangement. The system also may be configured to implement a method to set a security code in the transmitter and the receiver in order the signals generated are specific to a particular wheeled vehicle. The system may further include a braking force/pressure adjustment selector switch for setting a force/pressure of braking pressure or force applied to a vehicle's braking mechanism. The system also may include a mode selection switch for selecting any one of various forms of braking force/pressure, such as intermittent or continuous applications, and/or for selecting or setting audible and/or visual warnings that braking action is imminent or in progress.
