We describe a capnometer for analysing respiratory system function of a patient, the capnometer comprising: a memory to store patient data which is specific to said patient; and a signal processor to analyse a COwaveform representing a variation over time in a COlevel of air inhaled and/or exhaled by said patient.

Capnometer

A method of forming an organic light emitting diode comprising the steps of: providing a substrate comprising a first electrode for injection of charge carriers of a first type; forming a charge transporting layer by depositing over the substrate a charge transporting material for transporting charge carriers of the first type, the charge transporting material being soluble in a solvent; treating the charge transporting layer to render it insoluble in the solvent; forming an electroluminescent layer by depositing onto the charge transporting layer a composition comprising the solvent, a phosphorescent material, and a host material; and depositing over the electroluminescent layer a second electrode for injection of charge carriers of a second type.

Optical device comprising a charge transport layer of insoluble organic material and method for the production thereof

An organic light emissive device, which comprises: an anode; a cathode; and an organic light emissive region between the anode and the cathode, which region comprises: a layer of blue light electroluminescent organic material which emits light having first CIE co-ordinates by exciton radiative decay; and a layer of longer wavelength electroluminescent organic material which intrinsically emits light having second CIE co-ordinates by exciton radiative decay; wherein the layers of blue light and longer wavelength materials are selected so that the organic light emissive region emits white light falling within a region having a CIE &#x3c7; coordinate equivalent to that emitted by a black body at 3000-9000K and CIE &#x3b3; co-ordinate of said light emitted by a black body.

Light emissive device

A semiconductive conjugated polymer comprising a first repeat unit comprising general formula I: 

Blue-shifted triarylamine polymer

A semiconductive polymer comprising a first repeat unit in the polymer backbone comprising general formula 1: 

Arylamine polymer

An optical device comprising an anode, a cathode comprising barium, strontium or calcium, and a layer of organic semiconducting material between the anode and the cathode wherein a layer of hole transporting and electron blocking material is located between the anode and the layer of organic semiconducting material.

Electroluminescent device

The invention relates to a method and apparatus for the application of material to form a layer of an organic electroluminescent device. The material is sputter deposited typically from at least one target of material held in respect to a magnetron in a coating chamber. The magnetrons used can be unbalanced magnetrons and/or are provided with other magnetrons and/or magnet arrays in a closed field configuration. The material is found to be deposited in a manner which prevents or minimises damage to the device and hence reduces or removes the need for a barrier layer to be applied.

Apparatus and method for the application of a material layer to display devices

A method of forming an optical device comprising the steps of: providing a substrate comprising a first electrode capable of injecting or accepting charge carriers of a first type; forming over the first electrode a first layer that is at least partially insoluble in a solvent by depositing a first semiconducting material that is free of cross-linkable vinyl or ethynyl groups and is, at the time of deposition, soluble in the solvent; forming a second layer in contact with the first layer and comprising a second semiconducting material by depositing a second semiconducting material from a solution in the solvent; and forming over the second layer a second electrode capable of injecting or accepting charge carriers of a second type wherein the first layer is rendered at least partially insoluble by one or more of heat, vacuum and ambient drying treatment following deposition of the first semiconducting material.

Optical device

A light-emitting device comprising: an anode; a cathode; and a light emitting region situated between the anode and the cathode, the light emitting region comprising an exciton generating layer and a phosphorescent layer, the exciton generating layer comprising an organic material, wherein the organic material of the exciton generating layer generates singlet and triplet excitons and emits light by fluorescent emission from the singlet excitons and the phosphorescent layer accepts the triplet excitons from the exciton generating layer and emits light by phosphorescent emission from the triplet excitons.

Light emitting device

A polymer for use in an optical device comprising a first, optionally substituted, repeat unit of formula and a second, optionally substituted, repeat unit of formula wherein each Ar and Ar' is the same or different and comprises an optionally substituted aryl or heteroaryl group and optionally a third, optionally substituted, repeat unit in a molar ratio of no greater than 5%, the third repeat unit having a formula &#x2014;Ar&#x2014;N(Ar)&#x2014;Ar&#x2014; and having a single nitrogen atom in its backbone.
