Abstract: A data processing apparatus having a memory configured to store tables having virtual to physical address translations, a cache configured to store a subset of the virtual to physical address translations and cache management circuitry configured to control transactions received from the processor requesting virtual address to physical address translations. The data processing apparatus identifies where a faulting transaction has occurred during execution of a context and whether the faulting transaction has a transaction stall or transaction terminate fault. The cache management circuitry is responsive to identification of the faulting transaction having a transaction terminate fault to invalidate all address translations in the cache that relate to the context of the faulting transaction such that a valid bit associated with each entry in the cache is set to invalid for the address translations.

Abstract: A cleaning appliance comprising a body that is connectable to a separating apparatus at an interface that defines an axis. The interface includes a first interface portion and a second interface portion that are connected to one another by a connector, wherein the connector includes at least one radially interlocking region extending about at least a portion of the interface.

Abstract: An apparatus and method for correcting errors in data accessed from a memory device. A plurality of read symbols are read from a memory device. Syndrome information is then determined from the n data symbols and associated m error correction code symbols. Error correction circuitry uses the syndrome information in order to attempt to locate each read symbol containing an error and to correct the errors in each of those located read symbols. Error tracking circuitry tracks which memory regions the located read symbols containing an error originate from, and, on detecting an error threshold condition, sets at least one memory region as an erasure memory region. The correction circuitry treats each read symbol as a located read symbol containing an error, such that the read symbols to be located are not all randomly distributed and more than PMAX read symbols containing errors can be corrected.

Abstract: A cleaner head comprising a main body rotatably coupled to a neck, and a locking arrangement operable to permit rotation of the main body relative to the neck when the cleaner head is positioned on a surface and to prevent rotation of the body relative to the next when the cleaner head is lifted off a surface. The locking arrangement therefore stops the cleaner head from rotating undesirably when the cleaner head is lifted away from a cleaning surface.

Abstract: The invention relates to substituted phenoxyacetic acids of formula (I), where the variables are as defined in claim 1, as useful pharmaceutical compounds for treating respiratory disorders, pharmaceutical compositions containing them, and processes for their preparation.

Abstract: A wand for an appliance includes first and second tubes and a support mechanism, in which the second tube slides telescopically within the first tube along a common axis. The first and second tubes are arranged to be selectively secured to one another in an extended position or to allow movement therebetween and the support mechanism is located between overlapping portions of the tubes. The support mechanism includes tapered portions arranged to provide support between the tubes at separate points along the common axis of the tubes. By supporting adjacent tubes at a plurality of points along the common axis, the tubes are held more firmly with respect to one another. One tapered portion is able to move with respect to the tubes along the common axis, which reduces play between the tubes.

Abstract: A contact cover for a notification appliance mounting plate is disclosed. In one embodiment, the contact cover includes a plastic body, wherein the plastic body is sized to cover less than an entire surface area of the notification appliance mounting plate, at least one piece of metal, a means for coupling said at least one piece of metal to said plastic body and one or more polarized tabs.

Abstract: A fan includes a nozzle and a device for creating a primary air flow through the nozzle. The nozzle includes a mouth for emitting the primary air flow, and defines a bore through which a secondary air flow from outside the fan is drawn by the primary air flow emitted from the mouth and which combines with the primary air flow to produce a combined air flow. To allow a user to adjust at least one parameter, for example at least one of the profile, orientation and the direction, of the combined air flow, the fan comprises an insert which is locatable at least partially within the bore of the nozzle. The fan may be provided with a set of such inserts.

Abstract: A fan assembly includes a nozzle and a device for creating an air flow through the nozzle. The nozzle includes an interior passage, a mouth for receiving the air flow from the interior passage, and a Coanda surface located adjacent the mouth and over which the mouth is arranged to direct the air flow. The mouth and the Coanda surface extend about an axis. The Coanda surface comprises a diffuser portion, the angle subtended between the axis and the diffuser portion of the Coanda surface varying about the axis.

Abstract: A method, including receiving a turbine filter unit in a plasma treatment system, wherein the turbine filter unit comprises a filter media assembled with a framework, and applying at least one plasma treatment coating to the turbine filter unit via the plasma treatment system.

Abstract: A control for an automatic washer to operate the washer through a wash cycle determined based upon various soils and stains in the substrate load to be washed with a wash liquor in a wash zone of the washer. The control has a plurality of stain/soil type entrées, which can be at least one of selected and detected, and cleaned with a particular wash cycle. The control has dispensing control over at least one wash liquor additive. The control has a user input to permit the user to customize the operation of the control with regard to the dispensing of the various wash liquor additive and a timing mechanism. The control has operational control over the particular wash cycles using the dispensing control to dispense additives to the wash liquor at selected times during the wash cycle.

Abstract: A black level control apparatus and method, particularly for a high-speed video camera (8). The apparatus (10,100) comprises an image signal channel (30,130) for receiving an image signal having a black level from an image sensing device (22,122); a black level sensing device (24,124) for generating a black level signal; a black level signal channel (40,140), independent from the image signal channel, for receiving the black level signal from the black level sensing device; a black level controller (60,160) for receiving an input signal based on the black level signal, measuring a difference between the input signal and a reference signal, generating a control signal based on the difference, outputting the control signal to the image signal channel to adjust the black level of the image signal, and feeding the control signal to the black level signal channel, such that the input signal is based on the black level signal and the control signal.

Abstract: A cyclonic separating apparatus for a cleaning appliance includes a plurality of cyclonic separators arranged in series for separating particles from a dirt- and dust-laden airflow, at least three collectors for collecting separated dirt and dust, and a closure member movable between a closed position in which the closure member closes an end of each collector and an open position in which separated dirt and dust can be emptied from the collectors. The ends of the collectors are separated by dividing walls. A seal is provided to seal between the closure member and the dividing walls when the closure member is in the closed position. This common seal between the dividing walls and the closure member is able to seal effectively even if the closure member is misaligned or incorrectly fitted.
