Abstract: A miniature mass spectrometer that may be coupled to an atmospheric pressure ionisation source is described. Ions pass through a small orifice from a region at atmospheric pressure or low vacuum, and undergo efficient collisional cooling as they transit a very short, differentially pumped ion guide. A narrow beam of low energy ions is passed through a small aperture and into a separate chamber containing the mass analyser.

Abstract: A hoist spooling assembly for spooling a cable about a drum while preventing relative movement between the cable and the drum. The hoist spooling assembly evenly delivers force from a roller to the cable while reducing the incidence of spooling problems, including mechanical wear of the cable and formation of loops and kinks in the cable.

Abstract: A logical framebuffer may identify pixels areas or blocks of an image that have changed between successive frames. The pixel values of these identified areas may be copied and/or scaled from more recent frames and merged into older frames stored in scanout buffers of an image display system to update older buffers. The logical framebuffer may compare image data at a resolution that is greater than or equal to the resolution of the scanout buffers. Scaling may be used to downscale changed pixel areas frames stored at the higher resolution of logical framebuffer that are to be copied into older frames at the lower resolution of the scanout buffers to update the older frames. Changed pixel areas may also be copied from a newer frame buffered at the lower resolution after the older frame. Latency may be reduced. Image processors, display systems, and methods are provided.

Abstract: A shape may be virtually generated from a formula specifying a scalable property of the shape that determines the appearance of the shape as the size of the shape is changed. Once the shape is generated, a reflection and/or shadow may be generated according to one or more customizable parameters specifying different properties of the reflection and/or shadow. Reflections and shadows may be regenerated with shapes each time the shapes are resized. Each generated shape, reflection, and/or shadow may then be outputted to a display. Systems, methods, and computer readable media are provided.

Abstract: Components such as turbine shafts are maintained coaxial with each other by a coupling ring. The coupling ring includes a body which is cylindrical when unstressed, and which has two arrays of projections each array engaging a respective cylindrical surface of recesses in the components. The body is flexible, and so is resiliently deformed by contact between the projections and the respective cylindrical surface. The projections of the two arrays are angularly out of phase with each other.

Abstract: Protective covers for pillows and mattress are wholly or partly made of layered polyolefin fabrics. The layered polyolefin fabrics used for the protective covers are sheets of material bonded together with an adhesive or other bonding methods. One of the layers of the laminated fabric is a nonwoven polyolefin fabric and another layer is a polyolefin film. The protective covers stop migration of dust mites and are also reusable. The covers are cleaned and sanitized using a washer and a dryer.

The upper wing-like element is larger than the lower wing-like element and the trailing edge of the lower wing-like element is adjacent the trailing edge of the upper wing-like element at the intersection. An included angle between the upper and lower wing-like elements at the intersection is less than, or equal to, 160 degrees.

Abstract: An elastic composite is provided in a disposable absorbent garment such as a diaper or training pants. The elastic composite has a base layer, a top layer, and an elastic construction disposed therebetween. The elastic construction includes a plurality of spaced apart (e.g. generally equally spaced apart) elastic elements (e.g. strands or threads) that are aligned in a generally cross machine direction and in generally parallel relation. Further, the top and base layers define a first longitudinally extending side edge and a second longitudinally extending side edge between which, the elastic construction is disposed. The elastic composite further includes an elasticized region, wherein the elastic construction is disposed, a first non-elasticized region disposed between the first side edge and the elasticized region, and a second non-elasticized region disposed between the second side edge and the elasticized region.

Abstract: An aircraft having a lift/propulsion unit which includes a power unit such as a turboshaft engine which drives a fan through a transmission mechanism. The fan discharges to vectoring nozzles which can be independently swivelled to provide lift or propulsion thrust. An output shaft of the transmission mechanism serves as the main shaft of a motor/generator of modular form. The motor/generator can act as a generator to charge an electrical storage device such as a battery, or as a motor to drive the fan, either alone or to supplement the output of engine. Reaction control nozzles are provided at extremities of the aircraft to provide stabilizing thrust. The aircraft is capable of vertical take off and hovering, with the vectoring nozzles swivelled to a lift position, and forward thrust with the vectoring nozzles swivelled to a propulsion position.

Abstract: A novel waterborne cultivator, which provides the benefits of known systems for culture of photosynthetic micro-organisms in a novel configuration, incorporating a simplified, two-phase rotary mixing and gas injection system, the two phases being liquid and gas (CO2). The mixing system provides optimum growth conditions through increased turbulent vertical mixing and increased levels of dissolved CO2 throughout the cultivator via injection of flue gas or other CO2-bearing gas stream. The system thus provides efficient capture and sequestration or reuse of CO2 while producing valuable biomass for food, feed, and fuel use. The waterborne configuration provides further benefits of passive temperature control and automatic leveling for consistent culture depth. Additional benefit is provided by an enclosed design which reduces contamination and evaporative loss by isolating the photosynthetic culture from the outside environment.

Abstract: A system and method for applying motion blur to an application window. Motion blur may be applied to pixel in a window by calculating a velocity vector for each pixel in the window with reference to velocity vectors calculated for each corner of the window. Motion blur may be implemented by placing a number of blur samples in a frame along the pixel velocity vector according to the size of the pixel vector, or by directionally downsampling then re-upsampling the content of the window. For a frame having multiple windows, the motion blur for each window may be determined independent of the motion of other windows or as a composite for windows moving together. According to an embodiment, for each pixel in the frame, the associated application window may be identified and the pixel blurred with reference to the corner velocities of the associated application window.

Abstract: A gap 6 between a stationary component 2 and a rotating component 4 is sealed by means of a leaf seal comprising an array of leaves 8, 9. The leaves 8, 9 are disposed in pairs, comprising a higher curvature leaf 8 and a lower curvature leaf 9 which contact each other resiliently at their tips 12. The contact at the tips 12 provides a damping effect. As a result, the tips 12 of the leaves 8, 9 are relatively stable when subjected to an air flow F, enabling damaging flutter to be suppressed.
