Wireless data network access architecture and methods enabling location-specific and/or user-specific provision of services or resources. In one embodiment, an end-user device makes a request for service within a wireless LAN (WLAN). A wireless access point (WAP) controller/policy server determines whether the user device meets criteria for a first user status or a second user status, and assigns the appropriate status to an identifier of the end-user device. When the user device is assigned the first user status, the user device is provided network access according to e.g., a first permissible bandwidth allocation. Otherwise, the user device is provided network access according to a second, different bandwidth allocation. The first and second user status may be assigned based on a location of the user device within e.g., a venue, a class of end-user device, end user application, an access pass associated with the user device, or yet other criteria.

An apparatus for manufacturing of 3D objects is provided. The apparatus includes a number of material deposition heads terminated by nozzles, of which one or two nozzles are configured to deposit a first material to form a first and second pattern layers. The pattern layers are laterally shifted from each other such that when the first and second pattern layers are deposited, a space (empty volume) with a varying cross section is formed. In some examples, two or more nozzles could be used to deposit the corresponding first and second pattern layers. The nozzles could move independent of each other.

The disclosed methods relate to forming microneedle arrays from a production mold that comprises a flexible mold material. The disclosed methods can be used to reproducibly manufacture undercut dissolvable and coated microneedle arrays with various shapes and structures.

A casting mould comprising: an inorganic or refractory mould, wherein the mould is configured to receive feedstock; wherein the feedstock is configured to be heated in situ. A reusable mould, reusable susceptor, and/or release agent may be incorporated. Method of manufacturing a mould, and casting a part employing 5 in situ heating, are also provided.

A method of designing a cooling circuit inside a mold that includes therein the cooling circuit that passes through an inlet and an outlet includes a control plane setting step, a reference plane setting step, an intersection line extraction step, and a circuit setting step. The control plane setting step sets a control plane that is perpendicular to the mold surface on the side which comes in contact with a material and that passes through the inlet and the outlet. The reference plane setting step sets a reference plane that is offset by a fixed distance from the mold surface to the inside of the mold. In the intersection line extraction step, an intersection line at which the control plane and the reference plane intersect is extracted. In the circuit setting step, the cooling circuit is set inside the mold along the intersection line.

Processes for forming orthodontic appliances and other dental inserts comprise scanning a patient's dental arch or a mould of a dental arch such as a traditional plaster mould, to form a digital dental arch file corresponding to the size and position of the patient's dental arch. The digital dental arch file contains data corresponding to a plurality of dimensions corresponding to portions of the patient's dental arch. The disclosed methods include the step of modifying the digital dental arch file to decrease at least one of said dimensions and then utilizing the modified digital dental arch file to form the desired orthodontic appliance and other dental insert.

A carrier having one or more non-planar surfaces may be embedded with one or more radioactive seeds. A spherical carrier may be substantially radially symmetrical around an axis or a spherical carrier may include a non-spherical portion, such as a tapered portion that extends from a spherical portion.

Custom radioactive seed carriers are fabricated pre-operatively and/or intra-operatively to more precisely match carrier specification of a radiation treatment plan for a particular patient. One or more carrier specification component, such as a 3D printer, injection molding system, machining component, or bioprinter, may be utilized to create the custom carrier.

This disclosure concerns a master model for the production of a mold, comprising: (a) a first part, a second part comprising a textured surface; wherein the first part and the second part are connected.

A method including: obtaining a part design file of a part; deriving, from the art design file, a central mold design; determining one or more fill points for the central mold design; and attaching one or more mating connectors to the determined one or more fill points to create a modular part mold file.
