20080198624 | LIGHT GUIDE ORIENTATION CONNECTOR - A light guide assembly and method of forming the assembly. The light guide assembly includes an elongate light guide having an optically smooth surface for propagating light along its length and a light emitting region extending along at least a portion of the light guide length. The light emitting region has light extraction structures extending into the elongate light guide to extract or reflect light radially from the light guide. The assembly also includes a light source connector coupled to the light input end of the light guide. The light input end has primary encoding orientation geometry. The light source connector has a first end with secondary encoding orientation geometry, configured to mate with the primary encoding orientation geometry, and an opposing second end configured to accept a light source. | 08-21-2008 |

20120170304 | CONNECTOR - A connector adapted for use in an illumination system comprising at least one optical element, such as an optical fibre. is disclosed. The connector comprises a housing dimensioned so that internally it retains at least one end portion of at least one optical element, and externally substantially follows the shape of the end portion(s) of the optical element(s). This forms a join between the ends of the optical element(s). A light source is also contained within the housing and positioned so as to illuminate the end portions of at least one optical element. Electrical connection means adapted to connect the light source to an external power supply are provided. The electrical connection means being moveable relative to the housing. The electrical connection means may be carried by a flexible substrate, or may be formed by slideable contacts within a light guide rail. | 07-05-2012 |

20130082630 | DETERMINING ROTOR POSITION IN SENSORLESS SWITCHED RELUCTANCE MOTORS - A method for determining the position of a moving rotor in a switched reluctance motor includes the steps of applying a voltage to a phase winding of the reluctance motor, sampling a signal representative of the current magnitude in this phase winding, detecting a feature of the second temporal derivative of the signal, and determining the position of the moving rotor taking into account the occurrence of this feature. Apparatus for carrying out the method is described. | 04-04-2013 |
