Abstract: An optical element 5 and associated methods for generating an optical element and apparatus comprising the optical element 5 comprising a first surface 10, a second surface 15, and a side wall structure 25 between the first and second surfaces. The side wall structure 25 has an internally reflecting profile such that optical radiation incident on the first surface at an angle less than or equal to an acceptance angle and then incident on the side wall structure is internally reflected to the second surface 15 by the side wall structure 25. A first cross section (1, figure 7) of the optical element side wall structure may have an internally reflecting profile which differs from that of a second cross section (3, figure 7) which is rotated with respect to the first cross section. The optical element may also have a plurality of subsequent cross sections which are rotated around a rotational axis relative to the first cross section, possessing differing internally reflecting profiles. The method of generating the optical element involves determining first and second internally reflecting profiles using ray tracing, preferably by means of a computer program product.

Title: Feeding member for a screw device for power generation or material handling
Inventor: FRANKLAND GORDON
IPC: F03B17/06
Filed: 2012-03-26
Abstract: An Archimedes screw device for power generation or material handling has a number of helical pipes supported around a central support structure. The helical pipes may be formed from pipe portions that are joined together and wound around the central cylinder. Attached to the upper end of each helical pipe are feeder members (scoops) that together form an annular aperture feeding the helical pipes. The number of feeder members and pipes is selected depending upon the design flow of the device. This enables a standard kit of central support and pipe portions to produce e.g. a water turbine with a fully annular inlet, regardless of the number of helical pipes selected for a particular installation, by providing different feeder members for respective numbers of helical pipes.

Title: Computer-aided design of vehicle rear-view mirrors
Inventor: GUPTA NIRAJ
IPC: G06F17/50
Filed: 2012-09-21
Abstract: A method for designing rear view mirrors 3,5 for a motor vehicle 1 comprises providing a virtual 3D model of the vehicle (vehicle model) and a virtual 3D model of the rear view mirror (mirror model), the mirror having a reflection surÂ­face E, whereupon the mirror model is arranged on the vehicle model. A virtual 3D model of an environment 7 (environment model) comprising at least one deÂ­fined field of view zone (e.g. F2, F4, F5) is generated. The vehicle model is merged with the environment model such that the field of view zone is adjacent to the model (as shown). The mirror model is checked and/or adjusted such that, when viewed from a virtual driverâ  s eye positions (OD,OE, figure 1), the field of view zone (e.g. F2) is visible in a virtual reflection image I upon the mirror model. CAD techniques use photo-rendering and/or ray-tracing to calculate the virtual reflection image. The payload of the vehicle may be taken into account when providing the vehicle model. Adjustment of the mirror model is achieved by modifying the mirror radius/radii of curvature or size of the reflection surface E. By using CAD techniques to simulate and predict the rear mirror field of view, the method may reduce the cost and time required with building and testing physical prototypes of mirrors, whilst ensuring the necessary mirror parameters to meet regulations are established.

A broadly equivalent decoding method is also proposed. Further methods are also disclosed that give variations in the manner in which the frame merit is determined.
