摘要:
The present leverages data hierarchies to provide a systematic means to determine data differences between equivalent data. This allows disparate data storage systems to efficiently determine divergent data locations by utilizing, for example, data signatures representative of varying degrees of data granularity. Comparative analysis can then be performed between the databases by employing an iterative approach until the desired level of data granularity is obtained. This allows, in one instance of the present invention, discrepant data to be determined without the transfer of large amounts of data and without requiring homogeneous data storage systems. Another instance of the present invention utilizes equivalent logical data views from non-identical data sets to determine data discrepancies. Yet another instance of the present invention determines discrepancies of a federated and/or integrated data system by employing reversible data statistical signatures, providing a simplistic transfer protocol and sheltering each data system from the other's complexities.

A power converter circuit can be operated in a constant-current mode when a monitored output current exceeds a specified over-current threshold. A value representing an output voltage of the power converter circuit can be compared to a soft-start voltage reference value. The soft-start voltage reference value can be set (or reset) to a value representing the output voltage of the power converter when the difference between the soft-start voltage reference value and the value representing the output voltage of the power converter is greater than a specified threshold. The output voltage of the power converter can be regulated using the soft-start voltage reference value as a target voltage including ramping the soft-start voltage reference value at specified rate to maintain the soft-start voltage reference value within a specified range of a specified regulated output voltage value, such as to constrain a slew rate of the regulated output voltage.

The present invention relates to a needle-like probe (1) for use in electrical potential sensing and RF ablation of tissue, a method of making such probes (1), and a probe array comprising a number of such probes (1). The probe (1) has an elongated body (2, 22) with one end (9,29) adapted for penetration of tissue. The body (2, 22) has sufficient rigidity to be inserted into the tissue. The elongated body (2, 22) also comprises two or more electrodes (7, 27) separated and spaced apart from each other along the elongated body (2, 22) by insulative material (8, 28). Each electrode (7, 27) has at least one electrical conductor (10, 11) coupled to the electrode (7, 27). The electrode (7, 27) is capable of delivering RF energy to the tissue surrounding the electrode (7, 27) and sensing the electrical potential of the tissue. Preferably, the two or more electrodes (7, 27) each comprises a metal band incorporated in the elongated body (2, 22) and optionally include a thermal sensing means for measuring the temperature at the interface between the electrode (7, 27) and the tissue. Still further, the elongated body (2, 22) can internally incorporate an elongated rigid member (14) for providing structural stiffening of the probe (1). The elongated rigid member (14) can be comprised of metal and is rigidly fixed to at least the one end (9,29) adapted for penetration of the tissue. Preferably, the two or more electrodes (7, 27) and the insulative material (8, 28) form a tubular structure and the interior cavity of the tubular structure is filled with matrix material (16). Preferably, the probe (1) comprises at least four electrodes (7, 27) and at least three insulative portions (8, 28) interleaved therewith. Optionally, the elongated body (2, 22) has a substantially arcuate or curved form.

Systems and methods for purchasing credits are described. The system includes a plurality of electronic transaction terminals, an activity table, a computing device, a financial account server, and a credit system. The electronic transaction terminals include a handheld device that receives patron input and are located at an activity table. The electronic transaction terminals are in electronic communication with the computing device and provide an electronic transaction request instruction. The system generates from the electronic transaction request instruction, an electronic transaction request that is communicated from the computing device to the financial account server. The computing device then receives an electronic transaction approval from the financial account server and generates an authorization to dispense credits to a patron. The computing device then communicates the authorization to dispense credits to the credit system associated with the activity table so that the patron receives the credits at the activity table.

A client device, a system and a method for enabling financial transactions for an electronic gaming machine is described. The client device includes an electronic gaming machine processor, a printer, a printer sharing module and a controller. The printer sharing module is electrically coupled to the printer and the electronic gaming machine processor. The controller is electrically coupled to the printer sharing module. The controller reroutes the communications between the electronic gaming machine processor and the printer and allows the controller to communicate with the printer so that the controller instructs the printer to print a voucher. The system also includes a wireless communications module that enables communications with at least one other wireless communication module over short distances using point to point or broadcast packets that allow for bi-directional data transmission between each client device located on a casino gaming floor.

A method, computer program product and processor for quantitatively registering a 2D endoscopic ROI in a 3D volumetric imaging dataset. An endoscopic dataset and a volumetric imaging are registered to a common coordinate system. A 2D endoscopic ROI is generated within the endoscopic imaging dataset. A 3D surface ROI is generated within the volumetric imaging dataset corresponding to the 2D endoscopic ROI, based on a projection of the 2D endoscopic ROI to the registered common coordinate system.
