A method and apparatus for adjusting an adjustable retaining structure. The adjustable retaining structure may be rotated, passively, about a spherical interface as a panel applies a load to the adjustable retaining structure.

Intraocular implants and methods of making intraocular implants are provided. The intraocular implant can include a lens body having a lens material and a mask having a mask material. The lens body can be secured to the mask. The mask material can include a modulus of elasticity that is greater than or equal to a modulus of elasticity of the lens material.

The present disclosure relates to a method for manufacturing a microneedle containing a coating part on a needle tip and an apparatus used for the method. When a microneedle is manufactured using the coating method and apparatus according to the present disclosure, a coating part in which a target material is impregnated can be easily inserted into skin and effective dissolution is possible. Further, the target material is allowed to show excellent skin permeability with the dissolution of the coating part of the microneedle manufactured according to the present disclosure, thereby a quantitative amount of target material can be effectively delivered into the skin.

A mold for casting a micro-scale structure includes an upper surface including a first cavity having a first depth. A negative pattern for an array of micro-scale structures is defined in a surface of the first cavity. The mold includes at least one second cavity having a second depth defined in the cavity outside of the negative pattern for the array of micro-scale structures. The at least one second cavity defines a negative pattern for a standoff of the micro-scale structure. A fabric retaining frame is disposed in the first cavity.

A method and apparatus for installing a fastener. A reactive structural force is generated in a first direction during installation of the fastener. A new reactive structural force is generated in a second direction opposite to the first direction during the installation of the fastener.

A simulated abdominal wall model that is ideal for practicing laparoscopic first entry surgical techniques is provided. The model includes a simulated abdominal wall portion captured between two frame elements of a support. The support is connectable to a surgical trainer. When connected to the trainer, the model provides a penetrable abdominal tissue portion for accessing an internal cavity of the trainer. The simulated abdominal wall includes a plurality of layers including a skin layer, a fabric posterior rectus sheath layer, a simulated fat layer of low-resilience polyurethane foam and at least two layers that provide distinctive haptic feedback upon penetration of the simulated transversalis fascia and muscle layers. The simulated abdominal wall includes a simulated umbilicus across several layers of simulated tissue.

The disclosure discloses a bionic digestive tract as well as a preparation method and application thereof, belonging to the field of bionic technologies and the field of biological technologies. The bionic digestive tract of the disclosure is prepared by mixing a base material (one or more of silica gel, latex and hydrogel) and auxiliary materials (silicone oil and a curing agent) in a certain mass ratio (the mass ratio of the base material to the silicone oil to the curing agent is 100:(0.5 to 10):(0.5 to 3.5)). The simulation performance of the bionic digestive tract is excellent, has strong consistency with a true human digestive tract in terms of performance, structure and function, can simulate the true states of food, drugs and microorganisms in a digestive system, and has great application prospects in the research process of food and drugs.

A method for producing an acoustic absorption structure comprising an acoustically resistive structure, an alveolar structure, a reflective layer and a plurality of acoustic elements positioned in the alveolar structure, against the acoustically resistive structure, the method comprising forming a skin forming enclosures of the acoustic elements by depositing a resin on a mold having a base on which are positioned projecting forms shaped like the cavities delimited by the enclosures of the acoustic elements, placing the mold supporting the resin together with the alveolar structure, the resin being intercalated between the mold and the alveolar structure, polymerizing the resin to simultaneously obtain a hardening of the skin and also the joint between the skin and the alveolar structure, and fitting the acoustically resistive structure and the reflective layer.

A method and apparatus for distributing a number of utilities. The number of utilities may be coupled between a number of utility sources and a utility fixture. The number of utilities may be coupled between the utility fixture and a mobile system.
