摘要:
The invention relates to a method and apparatus for monitoring an object of interest (100). According to the invention, a cushion (104) is inflated such that the inflated cushion extends inwards to envelop the object of interest (100), whereupon the pressure exerted on the object of interest (1600) by the inflated cushion (104) is measured and a signal is output to stop inflating when the pressure reaches a predefined threshold. After that, the volume of the inflated cushion is measured and the size of the object of interest (100) is derived from the volume of the inflated cushion (104). In this way, the invention can keep the object of interest still during monitoring. Furthermore, the size of the object of interest can be used for imaging reconstruction to improve the quality of reconstructed images.

This invention relates to a method and device for calibrating the offset of an imaging system. The core idea of the invention is to place a reference object in the measurement chamber of the imaging system, measure the signals associated with the reference object at different points of time, calculate the merit function based on changes of the parameters representing the electromagnetic property of the reference object, and derive an optimal set of offset data that minimizes the value of the merit function for compensating the offset of the system in subsequent image reconstructions. In one embodiment, the invention uses a reference object comprising a non-conductive envelope and a cavity which can be filled with a conductive fluid and emptied, and in this way reduces the imaging interference caused by the reference object during monitoring.

The invention relates to a method and a system for magnetic induction tomography, the system comprising: at least one transmitting coil for generating a primary magnetic field to be applied to the object of interest; and at least one measurement coil arrangement for measuring electric signals induced by a secondary magnetic field which is generated by the object of interest in response to the primary magnetic field, wherein the at least one measurement coil arrangement comprises a plurality of measurement coils which are positioned in substantially the same plane. By using a plurality of independent measurement coils positioned in a plane so as to replace a conventional single measurement coil, the measurement coil across which the measured difference voltage is most sensitive to a change of the secondary magnetic field can be selected for calculating the change of conductivity distribution, resulting in an improved sensitivity of a MIT system.

A mechanism is provided in a data processing system for de-duplication in a Web services environment. Responsive to receiving a signature for a portion of a request message from a client, the mechanism performs a query in a bit stream repository to determine whether the portion of the request message has been previously received. Responsive to determining the portion of the message has been previously received, the mechanism retrieves the portion of the message from the bit stream repository. The mechanism notifies the client that the portion of the message has been previously received such that the client does not send the portion of the message.

The invention disclosed herein includes nanocomplexes that are designed include enzymes that have complementary functional attributes and methods for using these nanocomplexes. Illustrative examples include nanocomplexes that comprise both an alcohol oxidase enzyme as well as a catalase enzyme. These nanocomplexes can be used in methods designed to lower blood alcohol levels in vivo, and/or to break down the toxic byproducts of alcohol metabolism. Consequently these nanocomplexes can be used to treat a variety of conditions resulting from the consumption of alcohol, including for example, acute alcohol intoxication.

According to one embodiment of the present invention, a method for integrating client and server deduplication systems may be provided. In this method, a first hash set of a previous backup session may be received from a server. The first hash set may comprise a plurality of cryptographic values generated using a plurality of data blocks of a first data set of a client. A second hash set may be generated using a plurality of data blocks of a second data set of the client. A deduplicated data set may be generated by the client according to the first hash set and the second hash set and may comprise a plurality of non-redundant data blocks of the second data set. The second hash set and the deduplicated data set may be transmitted to the server.
