摘要： A system for coordinated laser marking of mid-conveyance food includes a controller, multiple lasers, and one or more industrial components. The lasers are in network communication with the controller. The controller can send a first instruction set, having a first language, to a first laser, and a second instruction set, having a second language different from the first language, to a second laser, the first laser associated with a first conveyor of multiple conveyors, and the second laser associated with a second conveyor different from the first conveyor. During operation, the first laser applies a marking to a first product as the first product is conveyed along the first conveyor, based on the first instruction set. Also during operation, the second laser applies the marking to a second product as the second product is conveyed along the second conveyor, based on the second instruction set.

摘要： An article includes a ceramic material and features a machined surface that is characteristic of cold ablation laser machining, and the machined surface exhibits no visible oxidation. A laser machining apparatus and technique is based on cold-ablation, but is modified or augmented with an inert assist gas, to minimize deleterious surface modifications and mitigate the oxide formation associated with laser machining.

摘要： A pulsed laser printing module for a contact lens, comprises a steel mold, a pulsed laser device and a forming case. The steel mold is configured for transferring pigment. The pulsed laser device is configured for transmitting ultrashort laser pulses having pulse time widths less than 10−9 seconds. The ultrashort laser pulses etch the surface of the steel mold to remove a coating of the steel mold to form an etched layer. The forming case has a lower member and an upper member. The lower member is a concavity, and an inner surface of the lower member is provided with a lower curved surface. The upper member is provided with a protrusion corresponding to the lower member, and an outer surface of the protrusion is provided with an upper curved surface corresponding to the lower curved surface. The protrusion is capable of being placed in a concavity of the lower member to form a gap between the lower curved surface and the upper curved surface.

摘要： A dental appliance having an integrally formed reservoir and/or an ornamental design integrated thereon. The ornamental design can be selected or customized by a patient. The design can be created by directing energy to the dental appliance to alter a material property of at least a portion of the appliance to create the design. Alternatively, a groove or recess can be formed on a surface of the appliance to either mechanically retain an ornamental design or the groove or recess can be filled with ink to form the design. The appliance, including the integrally formed reservoir, can be formed using direct fabrication techniques.

摘要： A mount system and method of manufacture for e.g. a machine vision camera is disclosed. The mount system comprises a rectangular base, a lower clamp disc, an upper clamp disc, a tilting plate, an expansion clamp, and an O-ring. The expansion clamp comprises a tapered head screw and an expandable mandrel, both typically made of stainless steel. The mount system facilitates improved machine vision by enabling effective mounting of machine vision cameras in smaller spaces and/or spaces requiring unusual angles and intricate positioning. The mount system is also advantageous in inhospitable environments having harsh environmental factors. The mount system is also easier for machine vision personnel to learn and understand.

摘要： The invention relates to a layer structure containing: (A) a first transparent radiation-engravable layer (A) with a first surface a1) and a second surface a2) which runs substantially parallel to the surface a1), said first layer (A) having a colorful or black part-engraving, said engraving being generated by means of nonionizing electromagnetic radiation (E), on the first surface a1) which forms a first outer surface of the layer structure; (B) optionally an additional transparent radiation-engravable layer (B) with a first surface b1) facing towards the first layer (A) and another surface b2) facing away from the first layer (A) and running substantially parallel to the surface b1); and (C) optionally at least one additional transparent plastic layer (C), wherein the additional layer (C) is selectively provided in one of a group of options consisting of: on the face of the first surface a1) of the layer (A), on the face of the additional surface b2) of the additional layer (B), between the two layers (A) and (B), or, in the event of additional layers (C), a combination of at least two of said options, and an image of the colorful or black part-engraving is located on the surface of the layer structure in the form of a nontransparent structural modification forming an additional outer surface of the layer structure and lying opposite the first surface a1). The invention likewise relates to the production of the layer structure as well as to a security document containing the layer structure according to the invention.

摘要： 2D code patterns, such as digital watermark patterns, are formed on plastic objects by injection molding. In some implementations, a marked cell of the code pattern is not formed by a single mark on the mold surface, but by multiple discrete marks. Such marks can be exceedingly small (e.g., 50 microns or less—smaller than the width of a human hair), yet the resulting code pattern on the molded object is still readable from a distance. The small scale of the marks assures that the code pattern does not detract from object aesthetics, while also speeding the mold-marking process. Style transfer networks are employed in some implementations. The detailed technologies facilitate digital marking and identification of a great number of consumer plastic objects, thereby aiding recovery of such objects for recycling. Many other features and arrangements are also detailed.
