Methods and apparatus for compensating the effects of display signal propagation delay in a display panel are disclosed. The apparatus comprises circuitry in addition to conventional display driver circuitry for delaying display line timing signals by an amount approximating the delay found in corresponding display lines. By delaying display line timing signals, for example in a column driver, by an time approximately equal the delay experienced in a corresponding row enable signal line, capacitors associated with the display pixels charge more fully resulting in a more vivid display image. Methods for compensating the effects of display signal propagation delay involve generating a plurality of delayed display timing signals and activating display lines in response to those delayed timing signals.

A skin dressing, particularly a wound dressing, comprises oxidoreductase enzyme and, optionally, peroxidase enzyme, wherein the enzyme(s) are present in hydrated condition, e.g. being present in one or more hydrated hydrogels. The dressing is used by being located on the skin of a human or animal e.g. over a wound. The oxidoreductase enzyme catalyses a reaction that produces hydrogen peroxide from an appropriate substrate, the substrate either being naturally present in body fluids and/or being supplied separately and/or being incorporated into the dressing. The currently preferred oxidoreductase enzyme is glucose oxidase. The catalyses reaction of β-D-glucose substrate to give hydrogen peroxide and gluconic acid. A mixture of oxidoreductase enzyme can undergo reaction (optionally catalysed by the peroxidase enzyme) to produce a variety of species including reactive oxygen intermediates that have antimicrobial properties and that can therefore assist in promoting wound healing.

According to the present invention, a circuit and methods for enhancing the operation of SOI fabricated devices are disclosed. In a preferred embodiment of the present invention, a pulse discharge circuit is provided. Here, a circuit is designed to provide a pulse that will discharge the accumulated electrical charge on the body of the SOI devices in the memory subarray just prior to the first access cycle. As explained above, once the accumulated charge has been dissipated, the speed penalty for successive accesses to the memory subarray is eliminated or greatly reduced. With a proper control signal, timing and sizing, this can be a very effective method to solve the problem associated with the SOI loading effect. Alternatively, instead of connecting the bodies of all SOI devices in a memory circuit to ground, the bodies of the N-channel FET pull-down devices of the local word line drivers can be selectively connected to a reference ground. This would enable the circuit to retain most of the speed advantages associated with SOI devices while overcoming the loading problem described above. With this preferred embodiment of the present invention, the major delay caused by the bipolar loading effect is minimized while the speed advantage due to providing a lower, variable Vt effect is preserved. The overall body resistance of the individual devices has a minimal effect on the device body potential.

Methods and systems are provided for mitigating engine pre-ignition based on a feed-forward likelihood of pre-ignition and feedback from a pre-ignition event.

The enrichment may be followed by an enleanment to restore exhaust catalyst feed-gas oxygen levels. The mitigating steps may be adjusted based on engine operating conditions, a pre-ignition count, as well as the nature of the pre-ignition.

An electromagnetic fluid controller can prevent the action force of magnetic attraction between both abutting faces of an armature and a stator, and eliminate the necessity of a junction of the armature and a valve needle. Upon coil energization, the armature is attracted by an electromagnetic stator force, and the armature and the stator abut through a nonmagnetic material film. The nonmagnetic material film is formed of a material containing NiP on the end face of the stator with a thickness in a range from 30 to 100 micrometers. Thus, the action force of magnetic attraction between both the abutting faces upon deenergization of the coil can be prevented without providing an air gap, and delays in the timing of the separation of the armature from the stator can be decreased.

Methods of retarding the setting of a cement composition comprise including one or more secondary amines substituted with a carboxyl group or salts thereof (e.g., 3-hydroxy N,N′-iminodisuccinic acid) in the cement composition. The inclusion of such materials in cement compositions may be highly beneficial. In wellbores having BHCT's of less than or equal to about 250° F., the use of the secondary amine as the set retarder ensures that the thickening time of the cement composition is sufficient to allow the cement composition to be pumped to its desired downhole location. Further, the secondary amine may be used in combination with conventional set retarders to enhance the ability of those retarders to increase the thickening time of the cement composition at higher BHCT's, e.g., from about 250° F. to about 525° F.

The invention relates to a test specimen fixture for ultrasonic vibration assisted grinding/polishing, and belongs to the field of precision machining and ultra-precision machining. The test specimen fixture comprises an ultrasonic generator, a piezoelectric ceramic transducer, a conical amplitude-change pole, a workpiece clamping system and a trimming ring. Alternating current is converted into ultrasonic-frequency electric oscillation signals by the ultrasonic generator, and the ultrasonic-frequency electric oscillation signals are transmitted to the piezoelectric ceramic transducer by a collector ring. The ultrasonic-frequency electric oscillation signals are converted into ultrasonic-frequency mechanical vibration by the piezoelectric ceramic transducer. The small amplitude of the vibration outputted by the transducer is magnified by the conical amplitude-change pole, and the vibration with the magnified amplitude is transmitted to the workpiece clamping system, so that workpieces can ultrasonically vibrate in ultra-precision grinding/polishing procedures. The test specimen fixture has the advantages that the test specimen fixture is compact in structure, simple in operation and high in efficiency and applicability; the machining precision and the surface quality of each workpiece can be obviously improved; grinding/polishing conditions further can be improved, for example, cutting force and cutting heat can be reduced, and vibration can be eliminated or suppressed; the durability of a grinding disc and the durability of polishing cloth can be improved, and the like.
