Abstract: A display device including a first electrode, a liquid crystal layer positioned under and connected to the first electrode, a second electrode and a switchable optical layer. The switchable optical layer includes either a transparent state or a non-transparent state and is electrically switchable between the transparent state and the non-transparent state. The non-transparent state is selectively emissive state. The switchable optical layer is positioned above and connected to the second electrode. A third electrode is positioned between the liquid crystal layer and the switchable optical layer.

Abstract: A pneumatic control valve assembly for a sample conditioning system used to condition one or more fluid streams to be analyzed. A pneumatic valve control assembly comprises a housing being attachable to an enclosure of the sample conditioning system at a first interface. The assembly includes at least one electrically operated pneumatic solenoid valve located in the housing and adapted to controllably supply pressurized air through a flow passage extending through the first interface to a respective pneumatically controlled valve located in the conditioning system enclosure to operate the pneumatically controlled valve. The assembly includes electronic circuitry located in the housing and having at least one relatively high voltage control circuit for controlling power supplied to the solenoid valve.

Abstract: The present invention relates to an optical encoder for measuring movement. The optical encoder includes at least one light source for outputting light. Furthermore, the optical encoder includes a movable pattern. Furthermore, the optical encoder includes at least one photodetector for detecting the light reflected off the movable pattern, the movable pattern including regions of varying reflectivity for modulating the light from the at least one light source onto the at least one photodetector in response to movement of the pattern, wherein the at least one photodetector is configured to detect the light in detection instants in regular intervals. The light source may be a pulsed light source outputting light in pulses. Furthermore, user equipment including such an optical encoder and a method for measuring movement are disclosed.

Abstract: An electronic display such as a liquid crystal display (LCD) is disclosed. The display includes a substrate layer, a light source and a lightguide for directing light emitted from the light source into the display, wherein the lightguide is integrally formed with the substrate layer. A mobile telecommunications device incorporating the display according to the invention is also disclosed. As the lightguide and substrate layer are formed together, the display is thinner than known displays so the telecommunications device can be made smaller or more space provided for other components.

Abstract: A stream selector for a process analyzer prevents contamination of one sample from previous samples without requiring a common outlet header. The stream selector includes a valve manifold having a base plate and a series of valve modules individually removeably attached to the base plate. The base plate includes all the process connections for the fluid lines. Each valve module includes a module body with a pair of valve assemblies. The valve assemblies in each module are operated simultaneously through a common actuation passage. A poppet valve in each valve assembly has a valve head with a double-seated seal. The double seated seal controls the flow of fluid through a vent passage in the valve body; and between inlet and outlet passages in the valve body. The outlet passage from one valve assembly is fluidly-connected to the inlet passage of an adjacent valve assembly to create a double-block and bleed configuration. The downstream valve assembly is then connected to the process analyzer.

Abstract: A software architecture for use in program controlled telecommunications switching exchanges in which application modules are employed to provide services to users of a particular communications application. Resource modules provide specific functional elements of communications services to the application modules by having access to and control over the exchange hardware. Network protocols provide communication between the application modules within the exchange and interfaces provide communications between the resource modules and between application modules and resource modules within the exchange.

Abstract: An ultrasonic fuel-gauging system has a tank with several ultrasonic probes having reflectors spaced along their length. A vibrating cylinder densitometer is located at the bottom of the tank and provides an output to a control unit representative of fuel density at that location. The control unit calculates the speed of sound reflected from the reflector closest to the densitometer and uses this and the density measurement to calculate a fuel constant. The control unit calculates the density of fuel at different heights from the fuel constant and speed of sound measurements from other reflectors. From these density measurements the control unit calculates mean density and fuel mass.
