The present disclosure relates to an ultrasound phantom for a focused ultrasound wave. More specifically, the present invention provides an ultrasound phantom which mimics a body so as to correspond to a speed of sound in the body, in which agarose, sucrose, polydiacetylene vesicle, and distilled water are mixed, and a specific part onto which an ultrasound wave is irradiated by a focused ultrasound transducer is gradually discolored in accordance with a temperature.

A method of forming a device having a compliant member includes providing an elastomeric layer in an uncured state. The elastomeric layer is pre-cured to increase its viscosity. Subsequently, a bobbin and housing, each having an end, can be positioned such that their ends extend at least partially into the elastomeric layer. The elastomeric layer is cured to secure it to the bobbin housing. Examples of pre-cure and cure operations include one or more of a thermal cure, evaporative cure and ultraviolet cure, and the application of moisture, microwave energy and chemical additive. Due to the increased viscosity after the pre-cure, the migration of elastomeric material is substantially reduced relative to an uncured elastomeric material. The reduction in elastomeric material migration results in smaller menisci formed along the walls of the housing and bobbin, and reduced thinning of the compliant member formed at their ends.

An echogenic organ replica and method of manufacture using an additive manufacturing system are provided. The echogenic organ replica includes at least one lower acoustic impedance material and a higher acoustic impedance material distributed within the at least one lower acoustic impedance material. The resulting echogenicity of the echogenic organ replica varies in three dimensions across each of the one or more locations to substantially replicate an echogenicity associated with corresponding locations of in vivo organ tissue.

Embodiments of golf club heads and methods to manufacture golf club heads are generally described herein. In one example, a golf club head may have a body portion having a toe portion, a heel portion, a top portion, a sole portion, a front portion, a lead edge portion, a back portion, and an interior cavity. The golf club head may also have a polymer material partially or entirely filling the interior cavity. Other examples and embodiments may be described and claimed.

An article at least comprising two components contacting with each other, in which at least part of a surface of at least one of the two components being plated, is provided, which is excellent in plating adhesion and impact resistance and thus is hard to be damaged on the plated surface and excellent in appearance even when one of the two components is brought into contact with the plated part of the other component, and is preferably suppressed in occurrence of unpleasant sounds such as squeaking noise. At least one of the two components of the article is formed of a thermoplastic resin composition (X) comprising a rubber-reinforced aromatic vinyl resin (A) in at least part of the portion that contacts the plated portion of the other component.

According to one implementation, a composite material molding jig includes a rigid portion and a convex portion for forming a groove for inserting an optical fiber sensor. The rigid portion has a surface for laminating prepreg sheets. The convex portion is formed in a surface side of the rigid portion. Further, according to one implementation, a composite material molding method is a method for molding a composite material, on which the groove for inserting the optical fiber sensor has been formed, by heating and curing a laminated body of the prepreg sheets laminated on the above-mentioned composite material molding jig.

An ultrasonic probe and methods of manufacture are provided. The method can include depositing a base layer on a platform. The method can also include depositing a first portion of a first functional layer on the base layer. The method can further include positioning a first surface of an ultrasonic transducer on the first portion of the first functional layer. The transducer can further include a second surface opposite the first surface and opposed first and second sides. The first and second sides can be transverse to the first and second surfaces. The method can additionally include depositing a second portion of the first functional layer on the first and second sides of the transducer. The method can further include depositing a second functional layer upon the second surface of the transducer. The transducer can be encapsulated by the first functional layer and the second functional layer.

Methods for creating nodal vibration patterns in a granular material on a metal sheet, capturing the patterns in a working material and using the working material with the captured shapes to provide an end product. A tone is applied to the metal sheet which, based on the properties of the sheet and the tone frequency, create a specific pattern of nodal lines of vibration in the sheet. A particulate material placed on the sheet takes the shape of the nodal lines. An adhesive-coated sheet of working material is applied to the metal sheet and captures the particles in the shape of the nodal lines. The sheet of working material with the captured nodal line patterns is then used to produce a structure with strength, stiffness and other properties based on the embedded wave patterns. Alternately, the particles can be directly fused into a skeleton in the nodal line pattern shape.

A membrane for an electro-acoustic transducer comprised of at least one elastomer layer made using spray coating of a liquid elastomer solution is provided. The at least one layer of elastomer is made by spraying a liquid elastomer solution, which may comprise a silicone, onto a mold having the desired membrane geometry, allowing the solution to cure and remove the membrane from the mold. The mold can be configured to hold other components of an electro-acoustic transducer that will be attached to the membrane after the curing step.

A method is provided for manufacturing during which a first duct section is formed with a tubular first sidewall. A first opening extends through the tubular first sidewall. The forming of the first duct section includes disposing a first woven fiber sleeve over a first mandrel and disposing a polymer material with the first woven fiber sleeve. A second duct section is disposed with a tubular second sidewall. The forming of the second duct section includes disposing a second woven fiber sleeve over a second mandrel and disposing the polymer material with the second woven fiber sleeve. The second duct section is arranged with the first duct section. The second duct section engages the tubular first sidewall. The tubular second sidewall is located at and extends circumferentially around the first opening. A duct structure is formed by attaching the second duct section to the first duct section.
