Publication number: 20020123152Abstract: A miniaturized integrated sensor (50) useful for indicating the presence of a sample analyte is disclosed. The sensor (50) has a platform (52) with an upper surface (53) and a detector (62), light source (60), waveguide (58), and reflective fixtures (60,62) embedded in the platform (52). The light source (60) is preferably a light emitting diode and sits in a cup-shaped dimple (68) that directs light from the light source (60) toward one of the reflective fixtures (64) to uniformly distribute light across the waveguide (58). The waveguide (58) is coupled to an upper surface (53) of the sensor platform (52) and is coated with a thin film of indicator chemistry (70) which interacts with the sample analyte to produce optic signal changes that are measurable by the detector (62). A lead frame (51) in the platform (52) has pins (54, 55, 56) which provide the interface to the outside world.Type: ApplicationFiled: December 4, 2001Publication date: September 5, 2002Inventors: Richard A.

Patent number: 6399000Abstract: A non-planar formed body of particulate thermal insulating material is made by a method in which particulate insulating material is introduced into a porous envelope (1) and the envelope with the particulate insulating material is located in a forming means (2, 3). The forming means is operated such that compaction of the particulate material in the envelope is effected into a body of desired non-planar form, accompanied by a downwardly-directed flow of the particulate material towards at least one edge (7, 8) of the body (4). In this way a required density distribution of compacted material in the body is achieved.Type: GrantFiled: May 9, 2000Date of Patent: June 4, 2002Assignee: Microtherm International LimitedInventor: Geoffrey John Richard Carr
