Abstract: The present invention relates to a process of bringing at least one subject data set into registration or conformity with a reference data set by electronic methods, each data set being a representation of a respective object.

Abstract: Interference in ultrasound imaging when used in connection with high intensity focused ultrasound (HIFU) is avoided by employing a synchronization signal to control the HIFU signal. Unless the timing of the HIFU transducer is controlled, its output will substantially overwhelm the signal produced by ultrasound imaging system and obscure the image it produces. The synchronization signal employed to control the HIFU transducer is obtained without requiring modification of the ultrasound imaging system. Signals corresponding to scattered ultrasound imaging waves are collected using either the HIFU transducer or a dedicated receiver. A synchronization processor manipulates the scattered ultrasound imaging signals to achieve the synchronization signal, which is then used to control the HIFU bursts so as to substantially reduce or eliminate HIFU interference in the ultrasound image. The synchronization processor can alternatively be implemented using a computing device or an application-specific circuit.

Abstract: A transfer system for use in transferring cryogen from a source to a point of use, comprising a flexible conduit for through flow of cryogenic fluid, heating means external of the flexible conduit arranged to provide heat to a wall of the conduit, and control means associated with said heating means for maintaining the temperature of said wall of the conduit at a level whereby cryogenic fluid flowing through the conduit in maintained in Leidenfrost flow.

Abstract: A process for producing a substantially dry, low dusting, free flowing granular pigment composition comprises (a) contacting a fluidized bed of pigment and a granulating assistant, (b) optionally contacting the granules so obtained with a surfactant and (c) removing the dry granules from the bed.
