Abstract: Methods of making a golf ball that includes a lattice reinforced layer, which is a layer made of at least two materials with different properties, includes various injection and compression molding steps. In some embodiments, the lattice reinforced layer is manufactured using a shutoff molding technique so that the entire lattice reinforced layer is molded in the same mold. In other embodiments, a grid for the lattice layer is formed first, then filled using an injection molding technique.

Abstract: A perfusion bioreactor includes at least one ultrasonic transducer that can acoustically generate a multi-dimensional standing wave. The standing wave can be used to retain cells in the bioreactor, and can also be utilized to dewater or further harvest product from the waste materials produced in a bioreactor.

Abstract: Methods and systems for separating a first biomaterial from a second biomaterial can use functionalized material retained in a liquid-filled chamber at locales within an acoustic standing wave field. A culture suspension containing the first biomaterial and the second biomaterial flows into the liquid-filled chamber and at least portions of the first biomaterial with features complementary to the functionalized material becomes bound to the functionalized material while other portions of the culture suspension containing the second material pass through the chamber. The portion of the first biomaterial bound to the functionalized material is subsequently released from the liquid filled chamber.

Abstract: An acoustophoretic device is disclosed. The acoustophoretic device includes an acoustic chamber, an ultrasonic transducer, and a reflector. The ultrasonic transducer includes a piezoelectric material driven by a voltage signal to create a multi-dimensional acoustic standing wave in the acoustic chamber emanating from a non-planar face of the piezoelectric material. A method for separating a second fluid or a particulate from a host fluid is also disclosed. The method includes flowing the mixture through an acoustophoretic device. A voltage signal is sent to drive the ultrasonic transducer to create the multi-dimensional acoustic standing wave in the acoustic chamber such that the second fluid or particulate is continuously trapped in the standing wave, and then agglomerates, aggregates, clumps, or coalesces together, and subsequently rises or settles out of the host fluid due to buoyancy or gravity forces, and exits the acoustic chamber.

Abstract: Golf balls having one or more structural components that include a highly neutralized acid polymer with a high acid content and a uniformly increased density. The core of the golf ball may be made up of the highly neutralized acid polymer. The highly neutralized acid polymer may have desired hardness and flexural modulus values. The highly neutralized acid polymer enables the golf ball to provide consistent play characteristics.

Abstract: A series of multi-dimensional acoustic standing waves is set up inside a growth volume of a bioreactor. The acoustic standing waves are used to hold a cell culture in place as a nutrient fluid stream flows through the cell culture. The nutrient fluid stream dislodges some cells from the cell culture, which can then be recovered for cell therapy applications. The cell culture continues to expand and reproduce, permitting continuous recovery of cells from the bioreactor.

Abstract: An article includes a hybrid nanocomposite product, which includes a nanostructure array and a resin matrix contained among and/or around the nanostructure array. The array/matrix is placed in between layers of dry or resin-infused fiber composite to permit formation of a composite structure. The nanostructure array and/or the resin matrix may be disposed in an abutting relationship with other layers of a composite. The array/matrix can provide reinforcement of the composite in the z-direction. Transfer of resin into dry fiber forms may be provided when the array/matrix acts as a resin transfer medium. Nanostructure arrays with a resin matrix can be prepared to form a resin film product. Methods are presented for infusing composites via resin-transfer molding (RTM), vacuum-assisted resin transfer molding (VARTM), resin film infusion (RFI), or injection molding wherein a resin matrix film substantially maintains alignment and position of the nanostructure array during the infusion process.

Abstract: Devices for separating materials from a host fluid are disclosed. The devices include a flow chamber, an ultrasonic transducer, and a reflector. The ultrasonic transducer and reflector create an angled acoustic standing wave oriented at an angle relative to the direction of mean flow through the flow chamber. The angled acoustic standing wave results in an acoustic radiation force having an axial force component that deflects the materials, so that the materials and the host fluid can thus be separated. The angled acoustic standing wave can be oriented at an angle of about 20° to about 70° relative to the direction of mean flow through the flow chamber to deflect, collect, differentiate, or fractionate the materials from the fluid flowing through the device at flow rates of about 400 mL/min up to about 700 mL/min.

Abstract: A golf ball including one or more configurable materials allows the attributes of the golf ball, including physical properties and play characteristics, to be changed by selective exposure of energy from an energy source to the golf ball. The exposure to the energy from the energy source causes certain configurable materials within the golf ball to undergo a physical change in structure, thereby changing the attributes of the modified golf ball. A method of post production modification of a golf ball allows the attributes of the golf ball to be changed to meet the desired attributes of a consumer. A customization system including multiple stock golf ball sets with different configurations is used with different energy sources to produce a variety of modified golf balls having different attributes. A distribution system processes stock golf balls using post production modification processes to produce different modified golf balls to consumers.

Abstract: A golf ball comprises a core, a cover formed from an ionomer resin and disposed on the core, and a cured coating layer disposed on and in direct contact with the cover. The cured coating layer is formed from a topcoat coating composition comprising a polymeric component and a halogenated component. The halogenated component is present in an amount of from about 0.5 parts by weight to about 50 parts by weight based on 100 parts by weight of the polymeric component. A method of coating a cover of a golf ball includes applying the topcoat coating composition directly onto the cover. The method also includes, after applying, curing the topcoat coating composition to form a cured coating layer disposed on and in direct contact with the cover to thereby coat the cover.

Abstract: A series of multi-dimensional acoustic standing waves is set up inside a growth volume of a bioreactor. The acoustic standing waves are used to hold a cell culture in place as a nutrient fluid stream flows through the cell culture. Biomolecules produced by the cell culture are collected by the nutrient fluid stream and separated downstream of the cell culture.

Abstract: Acoustic perfusion devices for separating biological cells from other material in a fluid mixture are disclosed. The devices include an inlet port, an outlet port, and a collection port that are connected to an acoustic chamber. An ultrasonic transducer creates an acoustic standing wave in the acoustic chamber that permits a continuous flow of fluid to be recovered through the collection port while keeping the biological cells within the acoustic chamber to be returned to the bioreactor from which the fluid mixture is being drawn.
