Some embodiments of the invention are directed to electrochemical fabrication methods for forming structures or devices (e.g. microprobes for use in die level testing of semiconductor devices) from a core material and a shell or coating material that partially coats the surface of the structure. Other embodiments are directed to electrochemical fabrication methods for producing structures or devices (e.g. microprobes) from a core material and a shell or coating material that completely coats the surface of each layer from which the probe is formed including interlayer regions. Additional embodiments of the invention are directed to electrochemical fabrication methods for forming structures or devices (e.g. microprobes) from a core material and a shell or coating material wherein the coating material is located around each layer of the structure without locating the coating material in inter-layer regions.

Multi-layer, multi-material micro-scale and millimeter-scale devices with enhanced electrical and/or mechanical properties

Methods and apparatus for automatically preparing food for consumption in which preparation comprises dispensing, manipulation, heating, and other operations using a wide variety of ingredients. The methods and apparatus described use ingredients efficiently and maintain their quality, while avoiding contact between ingredients and apparatus to minimize the risk of system contamination.

Embodiments are directed to forming reentrant multi-layer micro-scale or millimeter scale three dimensional structures, parts, components, or devices where each layer is formed from a plurality of deposited materials and more specifically where each layer is formed from at least one metal structural material and at least one organic sacrificial material (e.g. polymer) that are co-planarized and a portion of the sacrificial material located on a plurality of layers is removed after formation of the plurality of layers via one or more plasma etching operations or one or more neutral radical etching operations.

Neutral radical etching of dielectric sacrificial material from reentrant multi-layer metal structures

RF and microwave radiation directing or controlling components are provided that may be monolithic, that may be formed from a plurality of electrodeposition operations and/or from a plurality of deposited layers of material, that may include switches, inductors, antennae, transmission lines, filters, hybrid couplers, antenna arrays and/or other active or passive components. Components may include non-radiation-entry and non-radiation-exit channels that are useful in separating sacrificial materials from structural materials. Preferred formation processes use electrochemical fabrication techniques (e.g. including selective depositions, bulk depositions, etching operations and planarization operations) and post-deposition processes (e.g. selective etching operations and/or back filling operations).

Miniature RF and microwave components and methods for fabricating such components

The present invention is a Distally Assembled Steerable Cannula (DASC), a robotically-manipulated device that can be deployed and extended within a patient's body by growing from its distal end, or can be used in non-medical applications. In some embodiments, growth occurs by sequentially assembling segments that interlock to form a rigid tube with a complex 3-D shape. The segments are individually transported through the growing cannula, and then assembled at the distal end. A segment can be wedge-shaped in profile, allowing adjustment of the local radius and plane of curvature of the cannula to be controlled by relative segment orientation.

Steerable extendable devices

The present disclosure relates generally to the field of tissue removal and more particularly to methods and devices for use in medical applications involving selective tissue removal. One exemplary method includes the steps of providing a tissue cutting instrument capable of distinguishing between target tissue to be removed and non-target tissue, urging the instrument against the target tissue and the non-target tissue, and allowing the instrument to cut the target tissue while automatically avoiding cutting of non-target tissue. Various tools for carrying out this method are also described.

A counterfeiting deterrent device according to one implementation of the disclosure includes a plurality of layers formed by an additive process. Each of the layers may have a thickness of less than 100 microns. At least one of the layers has a series of indentations formed in an outer edge of the layer such that the indentations can be observed to verify that the device originated from a predetermined source. According to another implementation, a counterfeiting deterrent device includes at least one raised layer having outer edges in the shape of a logo. A light source is configured and arranged to shine a light through a slit in a substrate layer of the device and past an intermediate layer to light up the outer edge of the raised layer. The layers of the device are formed by an additive process and have a thickness of less than 100 microns each.

Counterfeiting deterrent and security devices, systems, and methods

Some embodiments are directed to techniques for building single layer or multi-layer structures on dielectric or partially dielectric substrates. Certain embodiments deposit seed layer material directly onto substrate materials while others use an intervening adhesion layer material. Some embodiments use different seed layer and/or adhesion layer materials for sacrificial and structural conductive building materials. Some embodiments apply seed layer and/or adhesion layer materials in what are effectively selective manners while others apply the materials in blanket fashion. Some embodiments remove extraneous material via planarization operations while other embodiments remove the extraneous material via etching operations. Other embodiments are directed to the electrochemical fabrication of multilayer mesoscale or microscale structures which are formed using at least one conductive structural material, at least one conductive sacrificial material, and at least one dielectric material. In some embodiments the dielectric material is a UV-curable photopolymer.

Embodiments of invention are directed to tissue approximation instruments that may be delivered to the body of a patient during minimally invasive or other surgical procedures. In one group of embodiments, the instrument has an elongated configuration with two sets of expandable wings that each have spreadable wings that can be made to expand when located on opposite sides of a distal tissue region and a proximal tissue region and can then be made to move toward one another to bring the two tissue regions into a more proximate position. The instrument is delivered through a needle or catheter and is controlled by relative movement of a push tube and control wire wherein the control wire can be released from the instrument via rotation in a first direction and can cause release of the approximation device from tissue that it is holding by rotation in the opposite direction.

Additive manufacturing methods and apparatus are described for the direct, automated, tooling-less fabrication of composite parts with complex shapes such as fiber-reinforced composite parts with isotropic properties. In some embodiments, fibers parallel to one axis (e.g. Z) are provided initially (e.g., as a preform) and layers are fabricated by selectively curing a resin around these fibers while adding other fibers with other orientations. In some embodiments, fibers are rendered substantially transparent by immersing them in a refractive index matching liquid, thus allowing selective curing of a resin in the presence of the fibers.
