Abstract: An apparatus, method, system for 3-D printing that includes a nozzle and a movable platform, wherein the platform provides for a constant distance configuration of the platform relative to the extrusion emitter or nozzle thereby precluding the need to level the printer. The apparatus includes motion vectors associated with each direction of motion of the movable platform. A central point of origin is further provided for establishing the directions of movement of the movable cantilevered platform. The direction of motion of the motion vectors each pass through the central point of origin thereby providing a movable platform that stays a constant distance relative to the nozzle when moved in any planar direction within each layer.

Abstract: A variety of methods and arrangements for facilitating communication between an electronic device and a toy are described. In one aspect, the toy communicates with the electronic device using audio signals and/or conductive touch elements. Some embodiments involve an electronic device that is arranged to use light-based control signals to communicate with a toy. In various implementations, the toy includes a light/motion sensor that allows a user to interact with the toy.

Abstract: A system, apparatus, and method for 3D scanning and printing that includes a 3D printer device with a rotatable platform that can be controlled by an associated 3D image scanning device. The scanning device can be a smart phone or the like and can generate commands to move the rotatable platform of the printer in association with scanning operation. The smart phone can be detachably coupled to the 3D printer and perform the scan through an aligned aperture. The touch screen of the phone can serve as a control and status interface for the scanning operation. The resulting scan can be stored in a cloud based service where 3D processing can be further applied. The processed 3D printer file can be accessed by other devices connected to the cloud service. An object can thereby be scanned at one 3D printer location and sent to another 3D printer location via the cloud connection or a peer-to-peer network.

Abstract: In one aspect of the present invention, a toy arrangement involving a flickering, animated and/or luminescent toy object will be described. The toy arrangement includes a toy object having a light sensitive layer. A light source is arranged to illuminate the light sensitive layer with a pattern revealing light. The light sensitive layer is arranged to emit colored light in response to exposure to the pattern revealing light. In some implementations, the light source is arranged to vary the intensity of the pattern revealing light, which in turn can cause the colored light emitted from the toy object to fade, brighten and flicker. The toy arrangement may also include a speaker that emits sounds that are synchronized with changes in the colored light.

Abstract: In one aspect of the present invention, a toy arrangement involving a flickering, animated and/or luminescent toy object will be described. The toy arrangement includes a toy object having an ultraviolet sensitive layer. A light source is arranged to illuminate the ultraviolet sensitive layer with ultraviolet light. The ultraviolet sensitive layer is arranged to emit colored light in response to exposure to the ultraviolet light. In some implementations, the light source is arranged to vary the intensity of the ultraviolet light, which in turn can cause the colored light emitted from the toy object to fade, brighten and flicker. The toy arrangement may also include a speaker that emits sounds that are synchronized with changes in the colored light.

Abstract: A light source, a convex mirror and an optical sensor are disposed within a housing which is transparent to the range of wavelengths from the light source and of a low distortion scratch-resistant material. A game board is used with retro-reflective elements, such as moveable playing markers or game tokens, cards or regions affixed to and integrated into the game board. A data store stores the locations of the reflective elements and other game-related data, such as data needed to measure a player's score or position in a game or data to provide guided play. The convex mirror is disposed inside the housing such that light reflects from the light source, off the convex mirror, through the housing, and onto the game board.

Abstract: A game apparatus and a method using a light source, a convex mirror and an optical sensor, all disposed within a housing, are described. The housing is transparent to the range of wavelengths from the light source and is composed of a low distortion scratch-resistant material. A game board is also used along with retro-reflective elements, such as moveable playing markers or game tokens, cards or regions affixed to and integrated into the game board. A data store stores the locations of the reflective elements and other game-related data, such as data needed to measure a player's score or position in a game or data to provide guided play. The convex mirror is disposed inside the housing such that light reflects from the light source, off the convex mirror, through the housing, and onto the game board. The one or more retro-reflective elements, when placed on the game board, receive light emanated from the light source.

Abstract: A device (10) for the electrically assisted delivery of a therapeutic agent is described. The device (10) has rigid zones or regions (12, 14) which are physically connected by a flexible means (16) such as a web. The flexible means (16) permits the rigid zones (12, 14) to move independently with respect to each other while remaining physically connected or coupled. In a preferred embodiment, the rigid zones are physically and electronically coupled by the flexible means. In another embodiment, the device (500) comprises one or more rigid zones, the skin side of the rigid zone having a radius of curvature (520) which approximates that of the body site to which the device (500) is to be attached. A method of increasing the body surface conformability of an electrotransport device (50, 150, 170) is described. The method involves the step of intentionally placing rigid subcomponents (58, 36, 37) of the device in physically separate zones (52, 54; 152, 154, 156, 158; 172, 174, 176, 178) within the device.
