Publication number: 20130215433Abstract: It is a purpose of this invention to provide a Hover CMM to accurately measure an object. The Hover CMM comprises: a probe, an air vehicle and a localiser. The probe is mounted on the air vehicle. The air vehicle transports the probe around the surface of the object. The localiser tracks the position and orientation of the probe. The air vehicle is capable of hovering, slow and rapid movement. The measurements made by the probe are synchronised with the measurements made by the localiser. In a further embodiment, multiple probes, multiple air vehicles and multiple localisers can be provided in a system. In a further embodiment, the air vehicle has additional propulsion means for reducing wander. In another embodiment, the air vehicle is tethered. In a further embodiment, a gantry is provided for tethering the air vehicle. In another embodiment, a tilting means is provided to incline the probe relative to the air vehicle.Type: ApplicationFiled: October 12, 2010Publication date: August 22, 2013Inventor: Stephen James Crampton

Patent number: 7313264Abstract: A scanning apparatus and method for generating computer models of three-dimensional objects comprising means for scanning the object to capture data from a plurality of points on the surface of the object so that the scanning means may capture data from two or more points simultaneously, sensing the position of the scanning means, generating intermediate data structures from the data, combining intermediate data structures to provide the model; display, and manually operating the scanning apparatus. The signal generated is structured light in the form of a stripe or an area from illumination sources such as a laser diode or bulbs which enable data for the position and color of the surface to be determined. The object may be on a turntable and may be viewed in real time as rendered polygons on a monitor as the object is scanned.Type: GrantFiled: June 20, 2003Date of Patent: December 25, 2007Assignee: 3D Scanners LimitedInventor: Stephen James Crampton

Patent number: 7184047Abstract: Apparatus for generating computer models of individuals is provided comprising a booth (1) that is connected to a server (2) via the Internet (3). Image data of an individual is captured using the booth (1) and a computer model corresponding to the individual is then generated by comparing the captured image data relative to a stored generic model. Data representative of a generated model is then transmitted to the server (2) where it is stored. Stored data can then be retrieved via the Internet using a personal computer (4) having application software stored therein. The application software on the personal computer (4) can then utilise the data to create graphic representations of an individual in any one of a number of poses.Type: GrantFiled: June 27, 2000Date of Patent: February 27, 2007Inventor: Stephen James Crampton

Patent number: 5908305Abstract: The device comprises a layer of silicon separated from a substrate by a layer of insulating material. A rib having an upper surface and two side surfaces is formed in the layer of silicon to provide a waveguide for the transmission of optical signals. A lateral doped junction is formed between the side surfaces of the rib such that an electrical signal can be applied across the junction to control the density of charge carriers across a substantial part of the cross-sectional area of the rib thereby actively altering the effective refractive index of the waveguide.Type: GrantFiled: May 22, 1998Date of Patent: June 1, 1999Assignee: Bookham Technology LimitedInventors: Stephen James Crampton, Arnold Peter Roscoe Harpin, Andrew George Rickman
