Abstract: A medicated module (4) for an injection system to co-deliver at least two medicaments is disclosed where a primary delivery device containing a primary medicament accepts a medicated module (4) containing a single dose of a secondary medicament and where both medicaments are delivered through a hollow needle (3). The medicated module (4) does not require the user to manually engage a reservoir (22) containing the secondary medicament. Instead, a biasing member (48) automatically activates the reservoir (22) when the needle guard (42) is retracted. The needle guard (42) prevents accidental needle sticks before and after an injection, and locks after dose delivery.

Abstract: Techniques are presented for performing maintenance operations, such as garbage collection, on non-volatile memory systems will still respecting the maximum latency, or time-out, requirements of a protocol. A safety guard band in the space available for storing host data, control data, or both, is provided. If, on an access of the memory, it is determined that the guard band space is exceeded, the system uses a recovery back to the base state by triggering and prioritizing clean-up operations to re-establish all safety guard bands without breaking the timing requirements. To respect these timing requirements, the operations are split into portions and done in a phased manner during allowed latency periods.

Abstract: A modified VOMAC mesh generation method for image data sampled from an actual object in which mesh resolution can vary locally within the mesh while permitting control of the distortion of cells in the mesh to maintain suitability for performing finite element (or finite volume) analysis on a representation of the object. The method includes computer-implemented instructions that calculate a variable sampling point distribution (SPD) in image data space, the variable SPD having localized variations in SPD within the image data space, and the distribution of sampling points having the same topology as a uniform SPD suitable for obtaining a regular structured is mesh. The method includes generating an indication of the magnitude of cell distortion between the generated mesh and the regular structured mesh Varying the mesh resolution may enable smaller elements to be located in regions of particular interest or activity when subsequently performing analysis using the mesh model.

Abstract: Disclosed is a safety needle assembly has a needle guard that prevents accidental needle sticks before and after an injection. A locking collar rotates during use as an inner protrusion follows three paths of a track located on the outer surface of a body housing. When the inner facing protrusion is in the third path, it encounters a hard stop and a rotational bias that locks the guard from further retraction and, thus, covers the sharp distal end of the needle.

Abstract: A medicated module for an injection system to co-deliver at least two medicaments is disclosed where a primary delivery device containing a primary medicament accepts a medicated module containing a single dose of a secondary medicament and where both medicaments are delivered through a hollow needle. The medicated module is user selectable so that it will deliver a priming dose of a primary medicament or both the primary and secondary medicaments. The module also contains a needle guard that locks after dose delivery. The needle guard prevents accidental needle sticks before and after an injection. A locking collar rotates during use as an inner protrusion follows three paths of a track located on the outer surface of a body housing. When the inner facing protrusion is in the third path, it encounters a hard stop and a rotational bias that locks the guard from further refraction and thus covers the sharp distal end of the needle.

Abstract: A non-volatile memory organized into flash erasable blocks sorts units of data according to a temperature assigned to each unit of data, where a higher temperature indicates a higher probability that the unit of data will suffer subsequent rewrites due to garbage collection operations. The units of data either come from a host write or from a relocation operation. Among the units more likely to suffer subsequent rewrites, a smaller subset of data super-hot is determined. These super-hot data are then maintained in a dedicated portion of the memory, such as a resident binary zone in a memory system with both binary and MLC portions.

Abstract: This invention relates to a transformer (1) for multi-output power supplies such as those commonly found in electronic equipment. The transformer comprises a magnetic core (3) and a plurality of windings (5, 7, 9) at least some of which are fractional windings, arranged about the magnetic core. The transformer comprises a dual transformer structure with a pair of transformers, a main transformer (11) and an auxiliary transformer (13). In a preferred embodiment, the main transformer and the auxiliary transformer are connected together. In this way, readily available magnetic components may be used in the construction of the transformer and the simple construction allows for a large cross-sectional area of transformer to be deployed so that reduced turn counts of windings may be used.

Abstract: A non-volatile memory system includes a memory section having a non-volatile cache portion storing data in a binary format, a primary user data storage section that stores user data in multi-state format, and an update memory area where the memory system stores data updating user data previously stored in the primary user data. The memory system allows a maximum number of blocks for use in the update memory area. When the memory system receives updated data corresponding to user data already written into the primary user data storage section, it determines whether a block of memory is available in the update memory area. In response to determining that a block of memory is not available in the update memory area, the system determines a block of the update memory to remove from the update memory; copies the data content of the determined update block into the cache portion of the memory section; and subsequently writes the updated data into the update memory.

Each image of the consecutive tissue sections is then analyzed and scored as appropriate. Using FACTS methods, pathologist time for annotation is reduced to a single slide. Optionally, multiple middle sections may be annotated for regions of interest and transferred accordingly.

Abstract: A power converter for delivering power to a load at a regulated voltage 11 includes a regulating stage receiving an unregulated supply 10 and having a main transformer 18. Switches 16a and 16b are arranged in a half-bridge connect the transformer primary 17 to the unregulated supply 10 to drive the load via a rectifying stage connected to the transformer secondary 19. The on-time of the switch is controlled by a controller 14 to effect the regulation over a range of values of the unregulated supply. An auxiliary transformer 103 has a secondary winding 104 connected in series with the main transformer primary 17 and a primary winding that is selectively driven via a switch 106. A comparator 107 detects a low voltage event within the regulating stage, such as a drop in the intermediate voltage at 10. The primary winding 105 of the auxiliary transformer 103 is driven during the low voltage event.

Abstract: A method for preparing image data for three-dimensional printing in which a digitised (e.g. voxelized) representation of a virtual three-dimensional object (e.g. CAD model) is eroded to create an internal volume for the object. Subsequently, a vector-based surface representation of this internal volume is generated and simply combined with a corresponding vector-based surface representation of the original virtual three-dimensional object to yield a hollowed out model in a format suitable for three-dimensional printing. A microstructure may be introduced into the interior of the hollowed out model, e.g. by extracting a volume corresponding to the inverse of that microstructure from the eroded digitised representation.

Abstract: The present invention relates to a power converter (90) and a method of operating same. There are numerous advantages to operating power converters using a series resonant converter (1, 21). This approach is particularly suitable for minimising switching losses in the power converter when it is operated at high frequency. However, there are problems with the known converters in that they are prone to generate noise in the acoustic spectrum due to the fact that the converter stages are often operating at different frequencies. The present invention relates to a power converter and a method of operating same that enables the operating frequency of the converter to be controlled by a control circuit over a predetermined range of the resonant frequency. This allows reduction in acoustic noise generation and facilitates frequency smearing that will in turn reduce spectral peaks. This is achieved whilst maintaining output ripple within acceptable ranges.
